また、前記補助部材の端面を通り前記ベース部材及び前記蓋板に直交する線を基準線とした場合に、前記摩擦攪拌工程では、摩擦攪拌を行った後に、前記回転ツールの片側のみに前記補助部材が残存する程度に、前記回転ツールの回転中心軸を前記基準線よりもわずかに前記補助部材の中央側に偏移させて、前記攪拌ピンを相対移動させるとともに、残存する前記補助部材にバリが形成されるように接合条件を設定することが好ましい。   Further, when a line passing through the end face of the auxiliary member and orthogonal to the base member and the cover plate is used as a reference line, in the friction stirring step, after the friction stirring is performed, the auxiliary tool is applied only to one side of the rotating tool. To the extent that the member remains, the rotation center axis of the rotary tool is shifted slightly to the center side of the auxiliary member with respect to the reference line, the agitating pin is relatively moved, and the remaining auxiliary member is It is preferable to set the joining conditions so that.

かかる伝熱板の製造方法によれば、バリを除去する作業をより容易に行うことができる。また、回転ツールの回転中心軸を補助部材の端面よりもわずかに中央側に偏移させることで、接合部の金属不足をより確実に防ぐことができる。   According to such a method of manufacturing a heat transfer plate, the work of removing burrs can be performed more easily. Moreover, the metal shortage of a junction part can be prevented more reliably by shifting the rotation center axis of the rotary tool to the center side slightly from the end face of the auxiliary member.

本発明に係る伝熱板の製造方法によれば、接合部の金属不足を防ぐことができ、水密性及び気密性に優れた伝熱板を形成することができる。   According to the method for manufacturing a heat transfer plate according to the present invention, it is possible to prevent a metal shortage at the joint and to form a heat transfer plate excellent in water tightness and air tightness.

[第一実施形態]
本発明の第一実施形態に係る伝熱板の製造方法について図面を参照して詳細に説明する。第一実施形態に係る接合方法では、閉塞工程と、配置工程と、摩擦攪拌工程と、除去工程とを行う。なお、以下の説明における「表面」とは、「裏面」の反対側の面という意味である。
[First embodiment]
The manufacturing method of the heat exchanger plate which concerns on 1st embodiment of this invention is demonstrated in detail with reference to drawings. In the joining method according to the first embodiment, a closing process, an arranging process, a friction stirring process, and a removing process are performed. In the following description, “front surface” means a surface opposite to the “back surface”.

第一実施形態に係る伝熱板1は、図5に示すように、ベース部材2と蓋板3とで構成されている。ベース部材2と蓋板3とは摩擦攪拌接合により一体化されている。   As shown in FIG. 5, the heat transfer plate 1 according to the first embodiment includes a base member 2 and a lid plate 3. The base member 2 and the cover plate 3 are integrated by friction stir welding.

ベース部材2は、図1及び図3に示すように、直方体を呈する金属部材である。ベース部材2は、例えば、アルミニウム、アルミニウム合金、銅、銅合金、チタン、チタン合金、マグネシウム、マグネシウム合金等の摩擦攪拌可能な金属で形成されている。ベース部材2の表面2aには、凹溝12及び蓋溝13が形成されている。
蓋溝13は、側断面視矩形を呈する直線状の溝であり、図1の手前側から奥側に向けて延びている。蓋溝13は、底面13aと、底面13aから立ち上る側面13bとによって構成されている。
凹溝12は、蓋溝13の底面13a形成された直線状の溝であり、蓋溝13に沿って延びている。凹溝12は、流体を流通させるための流路となる溝である。この凹溝12に流体を流通させて熱交換を行うことができる。凹溝12の底面は、下方に向けて凸形状となるように円弧状に湾曲している。
As shown in FIGS. 1 and 3, the base member 2 is a metal member that has a rectangular parallelepiped shape. The base member 2 is made of a metal capable of friction stirring such as aluminum, aluminum alloy, copper, copper alloy, titanium, titanium alloy, magnesium, magnesium alloy, and the like. A concave groove 12 and a lid groove 13 are formed on the surface 2 a of the base member 2.
The lid groove 13 is a linear groove having a rectangular shape in a side sectional view, and extends from the near side to the far side in FIG. The lid groove 13 includes a bottom surface 13a and a side surface 13b that rises from the bottom surface 13a.
The concave groove 12 is a linear groove formed on the bottom surface 13 a of the lid groove 13, and extends along the lid groove 13. The concave groove 12 is a groove serving as a flow path for circulating a fluid. Heat can be exchanged by circulating a fluid through the concave groove 12. The bottom surface of the concave groove 12 is curved in an arc shape so as to protrude downward.

蓋板3は、平面形状の板状部材である。蓋板3は、摩擦攪拌可能な金属から適宜選択すればよいが、第一実施形態では、ベース部材2と同じ材料で形成されている。
蓋板3の板厚寸法は、蓋溝13の側面13bの高さ寸法と同一である。蓋板3は、蓋溝13にほぼ隙間なく挿入される形状になっている。
The lid plate 3 is a planar plate-shaped member. The lid plate 3 may be appropriately selected from metals that can be frictionally stirred. In the first embodiment, the lid plate 3 is formed of the same material as the base member 2.
The plate thickness dimension of the lid plate 3 is the same as the height dimension of the side surface 13 b of the lid groove 13. The lid plate 3 is shaped to be inserted into the lid groove 13 with almost no gap.

蓋溝13内に蓋板3を配置することにより、蓋溝13の側面13bと蓋板3の側面3cとの突合せ部J1が形成されている。突合せ部J1は、蓋板3の両側部に形成されている。突合せ部J1は、図5に示すように、摩擦攪拌接合によって接合されており、突合せ部J1に沿って塑性化領域W1が形成されている(図3参照)。   By disposing the lid plate 3 in the lid groove 13, a butted portion J <b> 1 between the side surface 13 b of the lid groove 13 and the side surface 3 c of the lid plate 3 is formed. The abutting portion J1 is formed on both sides of the lid plate 3. As shown in FIG. 5, the butt portion J1 is joined by friction stir welding, and a plasticized region W1 is formed along the butt portion J1 (see FIG. 3).

次に、本発明の伝熱板の製造方法について説明する。第一実施形態の伝熱板の製造方法では、閉塞工程と、配置工程と、摩擦攪拌工程と、除去工程とを行う。   Next, the manufacturing method of the heat exchanger plate of this invention is demonstrated. In the manufacturing method of the heat exchanger plate of the first embodiment, a closing process, an arranging process, a friction stirring process, and a removing process are performed.

閉塞工程は、図1に示すように、蓋溝13に蓋板3を挿入する工程である。閉塞工程では、蓋板3の裏面3bを蓋溝13の底面13aに重ねつつ、蓋板3の側面3cと蓋溝13の側面13bとを突き合わせる。
これにより、蓋板3の両側部に突合せ部J1が形成される。蓋板3の表面3aと、ベース部材2の表面2aとは面一になる。
The closing step is a step of inserting the lid plate 3 into the lid groove 13 as shown in FIG. In the closing step, the side surface 3 c of the lid plate 3 and the side surface 13 b of the lid groove 13 are abutted while overlapping the back surface 3 b of the lid plate 3 with the bottom surface 13 a of the lid groove 13.
Thereby, the butt | matching part J1 is formed in the both sides of the cover board 3. FIG. The surface 3a of the cover plate 3 and the surface 2a of the base member 2 are flush with each other.

配置工程は、ベース部材2の表面2aに補助部材4の裏面4bを重ね合わせて配置する工程である。つまり、配置工程では、補助部材4をベース部材2のみに配置する。
補助部材4は、蓋板3と同じ平面形状の板状部材である。補助部材4は、摩擦攪拌可能な金属であれば特に制限されないが、第一実施形態ではベース部材2及び蓋板3と同じ材料になっている。
The arranging step is a step of arranging the back surface 4 b of the auxiliary member 4 so as to overlap the front surface 2 a of the base member 2. That is, in the arrangement step, the auxiliary member 4 is arranged only on the base member 2.
The auxiliary member 4 is a plate-like member having the same planar shape as the lid plate 3. The auxiliary member 4 is not particularly limited as long as it is a metal capable of friction stirring, but in the first embodiment, the auxiliary member 4 is made of the same material as the base member 2 and the cover plate 3.

補助部材4の板厚は、後記する摩擦攪拌工程後の塑性化領域W1(図5参照)が金属不足にならないように適宜設定する。配置工程では、補助部材4の端面4cと突合せ部J1とが重なるように補助部材4を配置する。
補助部材4の大きさは、少なくとも突合せ部J1に沿って補助部材4が配置されるようにすればよい(図3参照)。補助部材4の大きさは、摩擦攪拌工程後の塑性化領域W1(図5参照)が金属不足にならないように、かつ、摩擦攪拌工程後の蓋板3の表面3aに補助部材4が残存しない程度に設定することが好ましい。
The plate | board thickness of the auxiliary member 4 is suitably set so that the plasticization area | region W1 (refer FIG. 5) after the friction stirring process mentioned later may not run short of a metal. In the arranging step, the auxiliary member 4 is arranged so that the end surface 4c of the auxiliary member 4 and the butting portion J1 overlap each other.
The size of the auxiliary member 4 may be such that the auxiliary member 4 is disposed at least along the butted portion J1 (see FIG. 3). The size of the auxiliary member 4 is such that the plasticized region W1 (see FIG. 5) after the friction stirring step does not run out of metal and the auxiliary member 4 does not remain on the surface 3a of the lid plate 3 after the friction stirring step. It is preferable to set the degree.

摩擦攪拌工程は、図2に示すように、接合用回転ツールFを用いて突合せ部J1を摩擦攪拌によって接合する工程である。接合用回転ツールFは、連結部F1と、攪拌ピンF2とで構成されている。接合用回転ツールFは、特許請求の範囲の「回転ツール」に相当する。接合用回転ツールFは、例えば工具鋼で形成されている。連結部F1は、摩擦攪拌装置の回転軸(図示省略)に連結される部位である。連結部F1は円柱状を呈している。   As shown in FIG. 2, the friction stirring step is a step of joining the butt joint J <b> 1 by friction stirring using the rotating tool F for joining. The joining rotary tool F includes a connecting portion F1 and a stirring pin F2. The joining rotary tool F corresponds to a “rotary tool” in the claims. The joining rotary tool F is made of, for example, tool steel. The connecting part F1 is a part connected to a rotating shaft (not shown) of the friction stirrer. The connecting portion F1 has a cylindrical shape.

攪拌ピンF2は、連結部F1から垂下しており、連結部F1と同軸になっている。攪拌ピンF2は連結部F1から離間するにつれて先細りになっている。攪拌ピンF2の長さは、補助部材4および蓋板3の板厚よりも大きくなっている。
攪拌ピンF2の外周面には螺旋溝が刻設されている。第一実施形態では、接合用回転ツールFを右回転させるため、螺旋溝は、基端から先端に向かうにつれて左回りに形成されている。言い換えると、螺旋溝は、螺旋溝を基端から先端に向けてなぞると上から見て左回りに形成されている。
The stirring pin F2 hangs down from the connecting portion F1 and is coaxial with the connecting portion F1. The stirring pin F2 is tapered as it is separated from the connecting portion F1. The length of the stirring pin F <b> 2 is larger than the thickness of the auxiliary member 4 and the cover plate 3.
A spiral groove is formed on the outer peripheral surface of the stirring pin F2. In the first embodiment, in order to rotate the joining rotary tool F to the right, the spiral groove is formed counterclockwise as it goes from the proximal end to the distal end. In other words, the spiral groove is formed counterclockwise as viewed from above when the spiral groove is traced from the proximal end to the distal end.

なお、接合用回転ツールFを左回転させる場合は、螺旋溝を基端から先端に向かうにつれて右回りに形成することが好ましい。言い換えると、この場合の螺旋溝は、螺旋溝を基端から先端に向けてなぞると上から見て右回りに形成されている。螺旋溝をこのように設定することで、摩擦攪拌の際に塑性流動化した金属が螺旋溝によって攪拌ピンF2の先端側に導かれる。これにより、被接合金属部材(ベース部材2、蓋板3及び補助部材4)の外部に溢れ出る金属の量を少なくすることができる。螺旋溝は省略してもよい。   In addition, when rotating the rotation tool F for joining counterclockwise, it is preferable to form a spiral groove clockwise as it goes to a front-end | tip from a base end. In other words, the spiral groove in this case is formed clockwise when viewed from above when the spiral groove is traced from the proximal end to the distal end. By setting the spiral groove in this way, the metal plastically fluidized during friction stirring is guided to the tip side of the stirring pin F2 by the spiral groove. Thereby, the quantity of the metal which overflows to the exterior of a to-be-joined metal member (base member 2, cover plate 3, and auxiliary member 4) can be decreased. The spiral groove may be omitted.

接合用回転ツールFは、マシニングセンタ等の摩擦攪拌装置に取り付けてもよいが、例えば、先端にスピンドルユニット等の回転手段を備えたアームロボットに取り付けてもよい。   The joining rotary tool F may be attached to a friction stirrer such as a machining center, but may be attached to, for example, an arm robot having a rotating means such as a spindle unit at the tip.

摩擦攪拌工程では、補助部材4の表面4aから突合せ部J1に右回転させた攪拌ピンF2のみを挿入し、被接合金属部材と連結部F1とは離間させつつ相対移動させる。言い換えると、攪拌ピンF2の基端部は露出させた状態で摩擦攪拌接合を行う。
そして、ベース部材2、蓋板3及び補助部材4と攪拌ピンF2とを接触させた状態で、突合せ部J1に沿って接合用回転ツールFを相対移動させる。
In the friction stirring step, only the stirring pin F2 rotated clockwise from the surface 4a of the auxiliary member 4 is inserted into the butting portion J1, and the metal member to be joined and the connecting portion F1 are moved relative to each other while being separated. In other words, the friction stir welding is performed with the base end portion of the stirring pin F2 exposed.
Then, with the base member 2, the cover plate 3, the auxiliary member 4 and the stirring pin F <b> 2 in contact with each other, the joining rotary tool F is relatively moved along the abutting portion J <b> 1.

第一実施形態では、図3に示すように、接合用回転ツールFの進行方向右側に補助部材4が位置するように接合用回転ツールFの進行方向を設定する。つまり、図2において右側の突合せ部J1では、接合用回転ツールFを図2の手前側から奥側に向けて相対移動させる。また、図2において左側の突合せ部J1では、接合用回転ツールFを図2の奥側から手前側に向けて相対移動させる。
第一実施形態では、一つの接合用回転ツールFを図2の手前側と奥側との間で往復移動させることで、左右の突合せ部J1を摩擦攪拌接合している。このとき、接合用回転ツールFの回転方向を反転させる必要がないため、作業効率を向上させることができる。
In the first embodiment, as shown in FIG. 3, the traveling direction of the joining rotary tool F is set so that the auxiliary member 4 is positioned on the right side in the traveling direction of the joining rotary tool F. That is, in the right abutting portion J1 in FIG. 2, the welding rotary tool F is relatively moved from the near side to the far side in FIG. Further, in FIG. 2, the joining rotary tool F is relatively moved from the back side to the near side in FIG.
In the first embodiment, the left and right abutting portions J1 are friction stir welded by reciprocally moving one joining rotary tool F between the near side and the far side in FIG. At this time, since it is not necessary to reverse the rotation direction of the joining rotary tool F, work efficiency can be improved.

接合用回転ツールFの回転方向及び進行方向は前記したものに限定されるものではなく適宜設定すればよい。例えば、接合用回転ツールFの進行方向右側に補助部材4を配置しつつ、接合用回転ツールFを左回転させてもよい。もしくは、接合用回転ツールFの進行方向左側に補助部材4を配置しつつ、接合用回転ツールFを左右いずれかに回転させてもよい。接合用回転ツールFの回転方向等の条件と補助部材4の好ましい位置関係については後記する。   The rotation direction and the traveling direction of the joining rotary tool F are not limited to those described above, and may be set as appropriate. For example, the joining rotary tool F may be rotated counterclockwise while the auxiliary member 4 is disposed on the right side in the traveling direction of the joining rotary tool F. Alternatively, the joining rotary tool F may be rotated to the left or right while the auxiliary member 4 is disposed on the left side in the traveling direction of the joining rotary tool F. The conditions such as the rotation direction of the joining rotary tool F and the preferred positional relationship of the auxiliary member 4 will be described later.

攪拌ピンF2の挿入深さは適宜設定すればよいが、第一実施形態では、図2に示すように、攪拌ピンF2が蓋溝13の底面13aに達するように設定する。これにより、蓋溝13の底面13aと蓋板3の裏面3bとの重合部も接合される。
摩擦攪拌工程では、被接合金属部材と連結部F1とは離間させつつ相対移動させる。言い換えると、攪拌ピンF2の基端部は露出させた状態で摩擦攪拌接合を行う。接合用回転ツールFの移動軌跡には摩擦攪拌された金属が硬化することにより塑性化領域W1が形成される(図3参照)。摩擦攪拌工程後は、図4に示すように、補助部材4の端部にバリVが形成される。
The insertion depth of the stirring pin F2 may be set as appropriate, but in the first embodiment, the stirring pin F2 is set so as to reach the bottom surface 13a of the lid groove 13 as shown in FIG. Thereby, the overlapping portion of the bottom surface 13a of the cover groove 13 and the back surface 3b of the cover plate 3 is also joined.
In the friction stirring step, the metal member to be joined and the connecting portion F1 are moved relative to each other while being separated from each other. In other words, the friction stir welding is performed with the base end portion of the stirring pin F2 exposed. A plasticized region W1 is formed in the movement locus of the welding rotary tool F by hardening of the friction-stirred metal (see FIG. 3). After the friction stirring step, burrs V are formed at the end of the auxiliary member 4 as shown in FIG.

除去工程は、図5に示すように、補助部材4をベース部材2から除去する工程である。除去工程では、例えば手作業により、補助部材4をベース部材2から離間する方向に折り曲げてベース部材2から除去する。これにより、ベース部材2と蓋板3とが接合される。   The removal step is a step of removing the auxiliary member 4 from the base member 2 as shown in FIG. In the removing step, the auxiliary member 4 is bent away from the base member 2 by, for example, manual work and removed from the base member 2. Thereby, the base member 2 and the cover plate 3 are joined.

以上説明した第一実施形態に係る伝熱板1の製造方法によれば、図4に示すように、ベース部材2と蓋板3とが接合されるとともに、ベース部材2及び蓋板3に加え、補助部材4も同時に摩擦攪拌接合することにより、接合部(塑性化領域W1)の金属不足を防ぐことができる。また、第一実施形態によれば、ベース部材2及び蓋板3の両方ではなく、ベース部材2のみに補助部材4を配置するだけで金属不足を防ぐことができる。
これにより、第一実施形態に係る伝熱板1の製造方法によれば、ベース部材2の表面2a及び蓋板3の表面3aに接合部の金属不足による窪みができるのを防ぐことができるとともに、伝熱板1の水密性及び気密性を向上させることができる。
According to the method for manufacturing the heat transfer plate 1 according to the first embodiment described above, the base member 2 and the lid plate 3 are joined together as shown in FIG. 4, and in addition to the base member 2 and the lid plate 3. The auxiliary member 4 is also subjected to friction stir welding at the same time, so that a metal shortage at the joint (plasticized region W1) can be prevented. Further, according to the first embodiment, it is possible to prevent metal shortage only by arranging the auxiliary member 4 only on the base member 2, not on both the base member 2 and the cover plate 3.
Thereby, according to the manufacturing method of the heat exchanger plate 1 which concerns on 1st embodiment, while the surface 2a of the base member 2 and the surface 3a of the cover plate 3 can prevent the hollow by the metal shortage of a junction part being made. The water tightness and air tightness of the heat transfer plate 1 can be improved.

また、第一実施形態では、摩擦攪拌工程によって補助部材4にバリVが形成されるが、除去工程においてバリVを補助部材4ごと取り除くことができる。これにより、バリVを除去する作業を容易に行うことができる。なお、補助部材4は除去装置等を用いてもよいが、第一実施形態では手作業で容易に補助部材4を取り除くことができる。   In the first embodiment, the burrs V are formed on the auxiliary member 4 by the friction stirring process. However, the burrs V can be removed together with the auxiliary member 4 in the removing process. Thereby, the operation | work which removes the burr | flash V can be performed easily. Although the auxiliary member 4 may use a removing device or the like, in the first embodiment, the auxiliary member 4 can be easily removed manually.

ここで、第一実施形態に係る伝熱板1の製造方法において、従来のようにショルダ部を金属部材に押し込みながら摩擦攪拌を行うと、ショルダ部と補助部材4との接触により補助部材4が外部に飛ばされてしまい接合部の金属不足を補うことができない。
しかし、第一実施形態では、図2に示すように、接合用回転ツールFの攪拌ピンF2のみをベース部材2、蓋板3及び補助部材4に接触させつつ摩擦攪拌を行うため、補助部材4が外部に飛ばされることなく接合部の金属不足を補うことができる。また、ショルダ部を接触させる場合に比べて摩擦攪拌装置に作用する負荷を低減することができる。
Here, in the method for manufacturing the heat transfer plate 1 according to the first embodiment, when frictional stirring is performed while pushing the shoulder portion into the metal member as in the conventional case, the auxiliary member 4 is brought into contact with the shoulder portion and the auxiliary member 4. It will be blown out and the metal shortage at the joint cannot be compensated.
However, in the first embodiment, as shown in FIG. 2, the frictional stirring is performed while only the stirring pin F <b> 2 of the rotating tool F for joining is brought into contact with the base member 2, the cover plate 3, and the auxiliary member 4. Can compensate for the lack of metal in the joint without being blown to the outside. Moreover, the load which acts on a friction stirrer can be reduced compared with the case where a shoulder part is made to contact.

第一実施形態では、図2に示すように、接合用回転ツールFのフロー側(retreating side:回転ツールの外周における接線速度から回転ツールの移動速度が減算される側)がベース部材2側(接合中心の基準線Xよりも左側)となるように接合用回転ツールFの移動方向と回転方向を設定している。接合用回転ツールFの回転方向及び進行方向は前記したものに限定されるものではなく適宜設定すればよい。   In the first embodiment, as shown in FIG. 2, the flow side (retreating side: the side on which the moving speed of the rotating tool is subtracted from the tangential speed on the outer periphery of the rotating tool) is the base member 2 side (as shown in FIG. The moving direction and the rotating direction of the welding rotary tool F are set so as to be on the left side of the reference line X at the welding center. The rotation direction and the traveling direction of the joining rotary tool F are not limited to those described above, and may be set as appropriate.

例えば、接合用回転ツールFの回転速度が遅い場合では、フロー側に比べてシアー側(advancing side:回転ツールの外周における接線速度に回転ツールの移動速度が加算される側)の方が塑性流動材の温度が上昇しやすくなるため、塑性化領域W1外のシアー側にバリVが多く発生する傾向にある。
一方、例えば、接合用回転ツールFの回転速度が速い場合、シアー側の方が塑性流動材の温度が上昇するものの、回転速度が速い分、塑性化領域W1外のフロー側にバリVが多く発生する傾向にある。
For example, when the rotation speed of the rotating tool F for welding is slower, the shear side (advancing side: the side where the moving speed of the rotating tool is added to the tangential speed on the outer periphery of the rotating tool) is more plastic flow than the flow side. Since the temperature of the material is likely to rise, many burrs V tend to be generated on the shear side outside the plasticized region W1.
On the other hand, for example, when the rotational speed of the rotating tool F for joining is high, the temperature of the plastic fluidized material increases on the shear side, but there are more burrs V on the flow side outside the plasticizing region W1 due to the higher rotational speed. Tend to occur.

第一実施形態では、接合用回転ツールFの回転速度を速く設定しているため、図4に示すように、塑性化領域W1外のフロー側にバリVが多く発生する傾向にある。つまり、補助部材4側にバリVを集約させることができる。また、接合用回転ツールFの回転速度を速く設定することにより、接合用回転ツールFの移動速度(送り速度)を高めることができる。これにより、接合サイクルを短くすることができる。   In the first embodiment, since the rotation speed of the joining rotary tool F is set high, as shown in FIG. 4, there is a tendency that many burrs V are generated on the flow side outside the plasticizing region W1. That is, the burrs V can be concentrated on the auxiliary member 4 side. Moreover, the moving speed (feeding speed) of the joining rotary tool F can be increased by setting the rotational speed of the joining rotary tool F faster. Thereby, a joining cycle can be shortened.

摩擦攪拌工程の際に、図2に示すように、接合用回転ツールFの進行方向のどちら側にバリVが発生するかは接合条件によって異なる。当該接合条件とは、接合用回転ツールFの回転速度、回転方向、移動方向、移動速度(送り速度)、攪拌ピンF2の傾斜角度(テーパー角度)、ベース部材2、蓋板3及び補助部材4の材質、補助部材4の厚さ等の各要素とこれらの要素の組合せで決定される。接合条件に応じて、バリVが多く発生する側が接合中心の基準線Xに対して補助部材4側となるように設定すれば、バリを除去する作業を容易に行うことができるため好ましい。   In the friction stirring process, as shown in FIG. 2, which side of the traveling direction of the welding rotary tool F generates the burr V varies depending on the joining conditions. The joining conditions include the rotational speed, rotational direction, moving direction, moving speed (feeding speed) of the rotating tool F for joining, the inclination angle (taper angle) of the stirring pin F2, the base member 2, the cover plate 3, and the auxiliary member 4. The material, the thickness of the auxiliary member 4 and the like and the combination of these elements. It is preferable to set the side where a large amount of burrs V are generated to be on the auxiliary member 4 side with respect to the reference line X at the center of bonding, depending on the bonding conditions, because it is possible to easily remove the burrs.

(第一実施形態の変形例)
次に、第一実施形態に係る伝熱板1の製造方法の変形例について説明する。
第一実施形態の変形例では、図6に示すように、蓋板3に接触するように補助部材4を配置している。また、接合用回転ツールFの回転方向も第一実施形態と相違する。
(Modification of the first embodiment)
Next, the modification of the manufacturing method of the heat exchanger plate 1 which concerns on 1st embodiment is demonstrated.
In the modification of the first embodiment, as shown in FIG. 6, the auxiliary member 4 is disposed so as to contact the cover plate 3. Further, the rotating direction of the joining rotary tool F is also different from that of the first embodiment.

第一実施形態の変形例における配置工程は、図6に示すように、蓋板3の表面3aと補助部材4の裏面4bとを面接触させる工程である。第一実施形態の変形例における配置工程では、左右の突合せ部J1に沿って二枚の補助部材4を配置する。また、補助部材4の端面4cと突合せ部J1とが重なるように補助部材4を配置する。つまり、配置工程では、補助部材4を蓋板3のみに配置する。   The arrangement process in the modification of the first embodiment is a process of bringing the front surface 3a of the cover plate 3 and the back surface 4b of the auxiliary member 4 into surface contact as shown in FIG. In the arrangement step in the modification of the first embodiment, two auxiliary members 4 are arranged along the left and right abutting portions J1. Moreover, the auxiliary member 4 is arrange | positioned so that the end surface 4c of the auxiliary member 4 and the butt | matching part J1 may overlap. That is, in the placement step, the auxiliary member 4 is placed only on the lid plate 3.

第一実施形態の変形例における配摩擦攪拌工程では、図7に示すように、接合用回転ツールFを左回転させるため、攪拌ピンF2の螺旋溝は基端から先端に向かうにつれて右回りに形成されている。   In the friction distribution stirring step in the modification of the first embodiment, as shown in FIG. 7, the spiral groove of the stirring pin F2 is formed clockwise as it goes from the proximal end to the distal end in order to rotate the welding rotary tool F counterclockwise. Has been.

第一実施形態の変形例では、突合せ部J1に左回転させた攪拌ピンF2のみを挿入し、被接合金属部材と連結部F1とは離間させつつ移動させる。これにより、突合せ部J1が摩擦攪拌接合される。   In the modified example of the first embodiment, only the stirring pin F2 rotated counterclockwise is inserted into the butting portion J1, and the metal member to be joined and the connecting portion F1 are moved while being separated from each other. Thereby, the butt portion J1 is friction stir welded.

なお、第一実施形態の変形例では、接合用回転ツールFを高速回転しているため、バリVはシアー側に比べてフロー側の方に多く発生する傾向にある。つまり、補助部材4側にバリVを集約させることができる。これにより、除去工程では、バリVを補助部材4ごと蓋板3から除去することができる。   In the modification of the first embodiment, since the joining rotary tool F is rotated at a high speed, more burrs V tend to be generated on the flow side than on the shear side. That is, the burrs V can be concentrated on the auxiliary member 4 side. Thereby, the burr | flash V can be removed from the cover plate 3 with the auxiliary member 4 at a removal process.

以上、本発明に係る第一実施形態について説明したが、これに限定されるものではなく本発明の趣旨を逸脱しない範囲において、適宜変更が可能である。例えば、第一実施形態では、図2に示すように、攪拌ピンF2が蓋溝13の底面13aに達しているが、攪拌ピンF2が蓋溝13の底面13aに到達しないように、攪拌ピンF2の挿入深さを設定してもよい。   The first embodiment according to the present invention has been described above. However, the present invention is not limited to this and can be modified as appropriate without departing from the spirit of the present invention. For example, in the first embodiment, as shown in FIG. 2, the stirring pin F2 reaches the bottom surface 13a of the lid groove 13, but the stirring pin F2 prevents the stirring pin F2 from reaching the bottom surface 13a of the lid groove 13. The insertion depth may be set.

[第二実施形態]
次に、本発明の第二実施形態に係る伝熱板1の製造方法について説明する。
第二実施形態に係る伝熱板1の製造方法は、図8に示すように、ベース部材2及び蓋板3の両方と接触するように補助部材4を配置する点で第一実施形態と相違する。第二実施形態に係る伝熱板1の製造方法では、第一実施形態と相違する部分を中心に説明する。
[Second Embodiment]
Next, the manufacturing method of the heat exchanger plate 1 which concerns on 2nd embodiment of this invention is demonstrated.
The manufacturing method of the heat transfer plate 1 according to the second embodiment is different from the first embodiment in that the auxiliary member 4 is disposed so as to be in contact with both the base member 2 and the cover plate 3 as shown in FIG. To do. The manufacturing method of the heat transfer plate 1 according to the second embodiment will be described with a focus on portions that are different from the first embodiment.

第二実施形態に係る伝熱板1の製造方法は、閉塞工程と、配置工程と、摩擦攪拌工程と、除去工程とを行う。第二実施形態の閉塞工程は、第一実施形態と同じであるため説明を省略する。   The manufacturing method of the heat exchanger plate 1 which concerns on 2nd embodiment performs the obstruction | occlusion process, an arrangement | positioning process, a friction stirring process, and a removal process. Since the closing process of the second embodiment is the same as that of the first embodiment, the description thereof is omitted.

第二実施形態における配置工程は、図8に示すように、ベース部材2の表面2a及び蓋板3の表面3aの両方と、補助部材4の裏面4bとを面接触させる工程である。第二実施形態における配置工程では、左右の突合せ部J1にそれぞれ重なるように二枚の補助部材4を配置する。また、補助部材4の中央部に突合せ部J1が重なるように補助部材4を配置する。   As shown in FIG. 8, the disposing step in the second embodiment is a step of bringing both the surface 2 a of the base member 2 and the surface 3 a of the cover plate 3 into surface contact with the back surface 4 b of the auxiliary member 4. In the arranging step in the second embodiment, the two auxiliary members 4 are arranged so as to overlap the left and right butting portions J1, respectively. Further, the auxiliary member 4 is arranged so that the butting portion J1 overlaps the central portion of the auxiliary member 4.

第二実施形態における摩擦攪拌工程は、図9に示すように、接合用回転ツールFを用いてベース部材2と蓋板3との突合せ部J1を摩擦攪拌によって接合する工程である。
第二実施形態では、接合用回転ツールFを右回転させるため、攪拌ピンF2の螺旋溝は基端から先端に向かうにつれて左回りに形成されている。
As shown in FIG. 9, the friction stirring step in the second embodiment is a step of joining the abutting portion J <b> 1 between the base member 2 and the lid plate 3 by friction stirring using the welding rotary tool F.
In the second embodiment, in order to rotate the welding rotary tool F to the right, the spiral groove of the stirring pin F2 is formed counterclockwise as it goes from the proximal end to the distal end.

第二実施形態における摩擦攪拌工程では、右回転させた攪拌ピンF2を補助部材4の表面4aから挿入する。第二実施形態では、補助部材4の幅方向の中央部に攪拌ピンF2を挿入する。また、第二実施形態では、突合せ部J1に達するように攪拌ピンF2の挿入深さを設定する。
第二実施形態では、突合せ部J1に右回転させた攪拌ピンF2のみを挿入し、被接合金属部材と連結部F1とは離間させつつ移動させる。
そして、ベース部材2、蓋板3及び補助部材4と攪拌ピンF2とを接触させた状態で、突合せ部J1に沿って接合用回転ツールFを相対移動させる。これにより、突合せ部J1が摩擦攪拌接合される。
なお、第二実施形態の接合用回転ツールFの進行方向は第一実施形態と同じである。また、第二実施形態では、接合用回転ツールFを高速回転しているため、バリVはシアー側に比べてフロー側の方に多く発生する傾向にある。
In the friction stirring step in the second embodiment, the stirring pin F <b> 2 rotated to the right is inserted from the surface 4 a of the auxiliary member 4. In the second embodiment, the agitation pin F <b> 2 is inserted into the central portion of the auxiliary member 4 in the width direction. In the second embodiment, the insertion depth of the stirring pin F2 is set so as to reach the abutting portion J1.
In the second embodiment, only the stirring pin F2 rotated to the right is inserted into the abutting portion J1, and the bonded metal member and the connecting portion F1 are moved while being separated from each other.
Then, with the base member 2, the cover plate 3, the auxiliary member 4 and the stirring pin F <b> 2 in contact with each other, the joining rotary tool F is relatively moved along the abutting portion J <b> 1. Thereby, the butt portion J1 is friction stir welded.
In addition, the advancing direction of the rotating tool F for joining of 2nd embodiment is the same as 1st embodiment. In the second embodiment, since the bonding rotary tool F is rotated at a high speed, more burrs V tend to be generated on the flow side than on the shear side.

第二実施形態における除去工程は、補助部材4をベース部材2及び蓋板3から除去する工程である。第二実施形態における除去工程では、第一実施形態の除去工程と同様に、手作業により、補助部材4をベース部材2及び蓋板3から離間する方向に折り曲げて蓋板3から除去する。   The removing step in the second embodiment is a step of removing the auxiliary member 4 from the base member 2 and the cover plate 3. In the removing step in the second embodiment, the auxiliary member 4 is bent from the base member 2 and the lid plate 3 by manual work and removed from the lid plate 3 by manual operation, as in the removing step of the first embodiment.

以上説明した第二実施形態に係る伝熱板1の製造方法によれば、図9に示すように、ベース部材2及び蓋板3に加え、補助部材4も同時に摩擦攪拌接合することにより、接合部の金属不足を防ぐことができる。これにより、ベース部材2の表面2a及び蓋板3の表面3aに窪みができるのを防ぐことができるとともに、伝熱板1の水密性及び気密性を向上させることができる。
また、第二実施形態では、攪拌ピンF2を補助部材4の中央部に対して容易に挿入することができるとともに、突合せ部J1の両側に補助部材4を配置する分、接合部の金属不足をより確実に防ぐことができる。
According to the manufacturing method of the heat transfer plate 1 according to the second embodiment described above, as shown in FIG. 9, in addition to the base member 2 and the cover plate 3, the auxiliary member 4 is also joined by friction stir welding at the same time. It is possible to prevent a shortage of metal in the part. Thereby, while being able to prevent the surface 2a of the base member 2 and the surface 3a of the cover plate 3 from being depressed, the water-tightness and airtightness of the heat transfer plate 1 can be improved.
In the second embodiment, the stirring pin F2 can be easily inserted into the central portion of the auxiliary member 4, and the auxiliary member 4 is disposed on both sides of the abutting portion J1, thereby reducing the metal shortage of the joint portion. This can be prevented more reliably.

また、第二実施形態では、摩擦攪拌工程によって補助部材4にバリVが形成されるが、除去工程においてバリVを補助部材4ごと取り除くことができる。これにより、バリVを除去する作業を容易に行うことができる。   In the second embodiment, the burrs V are formed on the auxiliary member 4 by the friction stirring process. However, the burrs V can be removed together with the auxiliary member 4 in the removing process. Thereby, the operation | work which removes the burr | flash V can be performed easily.

(第二実施形態の第一変形例)
次に、第二実施形態に係る伝熱板1の製造方法の第一変形例について説明する。
第二実施形態の第一変形例では、図10に示すように、補助部材4をベース部材2に配置しつつ、突合せ部J1を挟んで蓋板3側にわずかに突出するように配置している。つまり、補助部材4をベース部材2及び蓋板3の両方に配置しつつ、補助部材4に対するベース部材2と蓋板3との接触割合を変更している。
(First modification of the second embodiment)
Next, the 1st modification of the manufacturing method of the heat exchanger plate 1 which concerns on 2nd embodiment is demonstrated.
In the first modification of the second embodiment, as shown in FIG. 10, the auxiliary member 4 is disposed on the base member 2, and is disposed so as to slightly protrude toward the lid plate 3 with the butting portion J <b> 1 interposed therebetween. Yes. That is, the contact ratio between the base member 2 and the cover plate 3 with respect to the auxiliary member 4 is changed while the auxiliary member 4 is disposed on both the base member 2 and the cover plate 3.

第二実施形態の第一変形例における配置工程では、補助部材4の9割程度をベース部材2に配置し、残りの1割程度を蓋板3に配置する。つまり、突合せ部J1に対して補助部材4がわずかに蓋板3側に突出するように配置する。
第二実施形態の第一変形例では、摩擦攪拌工程後に蓋板3側(補助部材4との接触面積が少ない側)に補助部材4が残存しないように調節している。
In the arrangement step in the first modification of the second embodiment, about 90% of the auxiliary member 4 is arranged on the base member 2 and the remaining 10% is arranged on the cover plate 3. That is, the auxiliary member 4 is arranged so as to slightly protrude toward the lid plate 3 with respect to the abutting portion J1.
In the first modification of the second embodiment, the auxiliary member 4 is adjusted so as not to remain on the lid plate 3 side (side with a small contact area with the auxiliary member 4) after the friction stirring step.

第二実施形態の第一変形例における摩擦攪拌工程では、図11に示すように、接合用回転ツールFを右回転させるため、攪拌ピンF2の螺旋溝は基端から先端に向かうにつれて左回りに形成されている。なお、第二実施形態の第一変形例における攪拌ピンF2の移動方向は、第一実施形態における攪拌ピンF2の移動方向と同じである(図3参照)。摩擦攪拌工程では、接合用回転ツールFの回転中心軸が、突合せ部J1と重なるように相対移動させる。   In the friction stirring step in the first modification of the second embodiment, as shown in FIG. 11, the spiral groove of the stirring pin F2 rotates counterclockwise as it goes from the proximal end to the distal end in order to rotate the welding rotary tool F to the right. Is formed. In addition, the moving direction of the stirring pin F2 in the 1st modification of 2nd embodiment is the same as the moving direction of the stirring pin F2 in 1st embodiment (refer FIG. 3). In the friction stirring step, the rotation center axis of the welding rotary tool F is relatively moved so as to overlap the butting portion J1.

第二実施形態の第一変形例における摩擦攪拌工程では、突合せ部J1に右回転させた攪拌ピンF2のみを挿入し、被接合金属部材と連結部F1とは離間させつつ移動させる。これにより、突合せ部J1が摩擦攪拌接合される。
第二実施形態の第一変形例では、突合せ部J1を挟んで蓋板3側にわずかに補助部材4を突出させる分、接合部の金属不足をより確実に防ぐことができる。
In the friction stirring step in the first modification of the second embodiment, only the stirring pin F2 rotated to the right is inserted into the abutting portion J1, and the bonded metal member and the connecting portion F1 are moved while being separated from each other. Thereby, the butt portion J1 is friction stir welded.
In the first modified example of the second embodiment, the shortage of the auxiliary member 4 on the side of the lid plate 3 with the butting portion J1 interposed therebetween can prevent the shortage of the metal at the joining portion more reliably.

なお、第二実施形態の第一変形例では、接合用回転ツールFを高速回転しているため、バリVはシアー側に比べてフロー側の方に多く発生する傾向にある。つまり、補助部材4側にバリVを集約させることができる。これにより、除去工程においてバリVを補助部材4ごとベース部材2から除去することができる。   In the first modification of the second embodiment, since the joining rotary tool F is rotated at a high speed, more burrs V tend to be generated on the flow side than on the shear side. That is, the burrs V can be concentrated on the auxiliary member 4 side. Thereby, the burr | flash V can be removed from the base member 2 with the auxiliary member 4 in a removal process.

(第二実施形態の第二変形例)
次に、第二実施形態に係る伝熱板1の製造方法の第二変形例について説明する。
第二実施形態の第二変形例では、図12に示すように、補助部材4を蓋板3に配置しつつ、突合せ部J1を挟んでベース部材2側にわずかに突出するように配置している。つまり、補助部材4をベース部材2及び蓋板3の両方に配置しつつ、補助部材4に対するベース部材2と蓋板3との接触割合を変更している。また、接合用回転ツールFの回転方向も第二実施形態と相違する。
(Second modification of the second embodiment)
Next, the 2nd modification of the manufacturing method of the heat exchanger plate 1 which concerns on 2nd embodiment is demonstrated.
In the second modification of the second embodiment, as shown in FIG. 12, the auxiliary member 4 is arranged on the lid plate 3 and is arranged so as to slightly protrude toward the base member 2 with the butting portion J1 interposed therebetween. Yes. That is, the contact ratio between the base member 2 and the cover plate 3 with respect to the auxiliary member 4 is changed while the auxiliary member 4 is disposed on both the base member 2 and the cover plate 3. Further, the rotation direction of the joining rotary tool F is also different from that of the second embodiment.

第二実施形態の第二変形例における配置工程では、補助部材4の9割程度を蓋板3に配置し、残りの1割程度をベース部材2に配置する。つまり、突合せ部J1に対して補助部材4がわずかにベース部材2側に突出するように配置する。第二実施形態の第二変形例では、摩擦攪拌工程後にベース部材2側(補助部材4との接触面積が少ない側)に補助部材4が残存しないように調節している。   In the arrangement step in the second modification of the second embodiment, about 90% of the auxiliary member 4 is arranged on the cover plate 3 and the remaining 10% is arranged on the base member 2. That is, the auxiliary member 4 is arranged so as to slightly protrude toward the base member 2 with respect to the abutting portion J1. In the second modified example of the second embodiment, the auxiliary member 4 is adjusted so as not to remain on the base member 2 side (side with a small contact area with the auxiliary member 4) after the friction stirring step.

第二実施形態の第二変形例における摩擦攪拌工程では、図13に示すように、接合用回転ツールFを左回転させるため、攪拌ピンF2の螺旋溝は基端から先端に向かうにつれて右回りに形成されている。なお、第二実施形態の第二変形例における攪拌ピンF2の移動方向は、第一実施形態における攪拌ピンF2の移動方向と同じである(図3参照)。   In the friction stirring process in the second modification of the second embodiment, as shown in FIG. 13, the spiral groove of the stirring pin F2 rotates clockwise as it goes from the proximal end to the distal end in order to rotate the welding rotary tool F counterclockwise. Is formed. In addition, the moving direction of the stirring pin F2 in the 2nd modification of 2nd embodiment is the same as the moving direction of the stirring pin F2 in 1st embodiment (refer FIG. 3).

第二実施形態の第二変形例における摩擦攪拌工程では、突合せ部J1に左回転させた攪拌ピンF2のみを挿入し、被接合金属部材と連結部F1とは離間させつつ移動させる。これにより、突合せ部J1が摩擦攪拌接合される。
第二実施形態の第二変形例では、突合せ部J1を挟んでベース部材2側にわずかに補助部材4を突出させる分、接合部の金属不足をより確実に防ぐことができる。
In the friction stirring step in the second modification of the second embodiment, only the stirring pin F2 rotated counterclockwise is inserted into the butt portion J1, and the bonded metal member and the connecting portion F1 are moved while being separated from each other. Thereby, the butt portion J1 is friction stir welded.
In the second modified example of the second embodiment, the shortage of the auxiliary member 4 to the base member 2 side with the butting portion J1 interposed therebetween can be more reliably prevented from lacking the metal at the joint portion.

なお、第二実施形態の第二変形例では、接合用回転ツールFを高速回転しているため、バリVはシアー側に比べてフロー側の方に多く発生する傾向にある。つまり、補助部材4側にバリVを集約させることができる。これにより、除去工程においてバリVを補助部材4ごと蓋板3から除去することができる。   In the second modification of the second embodiment, since the joining rotary tool F is rotated at a high speed, more burrs V tend to be generated on the flow side than on the shear side. That is, the burrs V can be concentrated on the auxiliary member 4 side. Thereby, the burr | flash V can be removed from the cover plate 3 with the auxiliary member 4 in a removal process.

以上、本発明に係る第二実施形態について説明したが、これに限定されるものではなく、本発明の趣旨を逸脱しない範囲において、適宜変更が可能である。   The second embodiment according to the present invention has been described above. However, the present invention is not limited to this, and can be changed as appropriate without departing from the spirit of the present invention.

[第三実施形態]
次に、本発明の第三実施形態に係る伝熱板1の製造方法について説明する。
第三実施形態に係る伝熱板1の製造方法は、図14に示すように、ベース部材2の凹溝12に熱媒体用管15を挿入する点で第一実施形態と相違する。第三実施形態に係る伝熱板1の製造方法では、第一実施形態と相違する部分を中心に説明する。
[Third embodiment]
Next, the manufacturing method of the heat exchanger plate 1 which concerns on 3rd embodiment of this invention is demonstrated.
As shown in FIG. 14, the method for manufacturing the heat transfer plate 1 according to the third embodiment is different from the first embodiment in that the heat medium pipe 15 is inserted into the concave groove 12 of the base member 2. In the method for manufacturing the heat transfer plate 1 according to the third embodiment, a description will be given focusing on portions that are different from the first embodiment.

第三実施形態に係る伝熱板1の製造方法は、熱媒体用管挿入工程と、閉塞工程と、配置工程と、摩擦攪拌工程と、除去工程とを行う。第三実施形態では、熱媒体用管挿入工程以外の各工程は、第一実施形態と同じであるため説明を省略する。   The manufacturing method of the heat exchanger plate 1 which concerns on 3rd embodiment performs the pipe | tube insertion process for heat media, a blockade process, an arrangement process, a friction stirring process, and a removal process. In 3rd embodiment, since each process other than the pipe insertion process for heat media is the same as 1st embodiment, description is abbreviate | omitted.

第三実施形態の熱媒体用管15は、図14に示すように、断面視円形の円筒管である。また、熱媒体用管15の外径は、凹溝12の幅と略同等に形成されており、熱媒体用管15の下半部と凹溝12の底面とが面接触している。また、熱媒体用管15の上端は、蓋板3の裏面3bと線接触している。
熱媒体用管15は、例えば、冷却水、冷却ガス、高温液、あるいは高温ガスなどの熱媒体を循環させて、ベース部材2に熱を伝達させる部材である。
なお、第三実施形態の熱媒体用管15は、断面視円形としたが、断面視角形であってもよい。また、熱媒体用管15は、第三実施形態においては、銅管を用いたが、他の材料の管を用いてもよい。
As shown in FIG. 14, the heat medium pipe 15 of the third embodiment is a cylindrical pipe having a circular cross-sectional view. Further, the outer diameter of the heat medium pipe 15 is formed substantially equal to the width of the groove 12, and the lower half of the heat medium pipe 15 and the bottom surface of the groove 12 are in surface contact. Further, the upper end of the heat medium pipe 15 is in line contact with the back surface 3 b of the cover plate 3.
The heat medium pipe 15 is a member that circulates a heat medium such as cooling water, cooling gas, high-temperature liquid, or high-temperature gas, and transmits heat to the base member 2.
The heat medium pipe 15 of the third embodiment is circular in cross section, but may be square in cross section. In addition, although the copper pipe is used as the heat medium pipe 15 in the third embodiment, a pipe made of another material may be used.

第三実施形態における熱媒体用管挿入工程では、凹溝12内に熱媒体用管15を挿入する。
第三実施形態における配置工程は、ベース部材2の表面2aと補助部材4の裏面4bとを面接触させる工程である。第三実施形態における配置工程では、補助部材4の端面4cと突合せ部J1とが重なるように補助部材4を配置する。
In the heat medium tube insertion step in the third embodiment, the heat medium tube 15 is inserted into the groove 12.
The disposing step in the third embodiment is a step of bringing the surface 2a of the base member 2 and the back surface 4b of the auxiliary member 4 into surface contact. In the arrangement step in the third embodiment, the auxiliary member 4 is arranged so that the end surface 4c of the auxiliary member 4 and the butted portion J1 overlap each other.

第三実施形態における摩擦攪拌工程では、図15に示すように、接合用回転ツールFを右回転させるため、攪拌ピンF2の螺旋溝は基端から先端に向かうにつれて左回りに形成されている。なお、第三実施形態における攪拌ピンF2の移動方向は、第一実施形態における攪拌ピンF2の移動方向と同じである(図3参照)。
そして、右回転させた攪拌ピンF2のみを補助部材4の表面4aから突合せ部J1に挿入し、接合用回転ツールFの回転中心軸と突合せ部J1とを重ね合わせつつ、被接合金属部材と連結部F1とは離間させて移動させる。これにより、突合せ部J1が摩擦攪拌接合される。
In the friction stirring step in the third embodiment, as shown in FIG. 15, the spiral groove of the stirring pin F <b> 2 is formed counterclockwise from the proximal end toward the distal end in order to rotate the welding rotary tool F to the right. In addition, the moving direction of the stirring pin F2 in 3rd embodiment is the same as the moving direction of the stirring pin F2 in 1st embodiment (refer FIG. 3).
Then, only the stirring pin F2 rotated to the right is inserted from the surface 4a of the auxiliary member 4 into the abutting portion J1, and the rotation center axis of the welding rotary tool F and the abutting portion J1 are overlapped with each other to be joined to the metal member to be joined. It is moved away from the part F1. Thereby, the butt portion J1 is friction stir welded.

なお、第三実施形態では、接合用回転ツールFを高速回転しているため、バリVはシアー側に比べてフロー側の方に多く発生する傾向にある。つまり、補助部材4側にバリVを集約させることができる。これにより、除去工程では、バリVを補助部材4ごとベース部材2から除去することができる。   In the third embodiment, since the joining rotary tool F is rotated at a high speed, more burrs V tend to be generated on the flow side than on the shear side. That is, the burrs V can be concentrated on the auxiliary member 4 side. Thereby, the burr | flash V can be removed from the base member 2 with the auxiliary member 4 at a removal process.

以上説明した第三実施形態に係る伝熱板1の製造方法によれば、図15に示すように、ベース部材2及び蓋板3に加え、補助部材4も同時に摩擦攪拌接合することにより、接合部の金属不足を防ぐことができる。これにより、ベース部材2の表面2a及び蓋板3の表面3aに窪みができるのを防ぐことができるとともに、伝熱板1の水密性及び気密性を向上させることができる。   According to the manufacturing method of the heat transfer plate 1 according to the third embodiment described above, as shown in FIG. 15, in addition to the base member 2 and the cover plate 3, the auxiliary member 4 is also joined by friction stir welding at the same time. It is possible to prevent a shortage of metal in the part.

In the fourth embodiment, as shown in FIG. 20, the concave groove 12 is formed on the surface 2 a of the base member 2.
In the closing process in the fourth embodiment, a single cover plate 3 is overlaid on the surface 2 a of the base member 2 so as to cover the concave groove 12. Thereby, the superposition | polymerization part J2 is formed.
The disposing step in the fourth embodiment is a step of bringing the front surface 3a of the cover plate 3 and the back surface 4b of the auxiliary member 4 into surface contact. In the arranging step in the fourth embodiment, two auxiliary members 4 are arranged on both sides of the central portion in the width direction of the groove 12.

第四実施形態における摩擦攪拌工程では、図21に示すように、右回転させた攪拌ピンF2を補助部材4の表面4aから挿入する。第四実施形態では、補助部材4の幅方向の中央部に攪拌ピンF2を挿入する。また、第四実施形態では、攪拌ピンF2がベース部材2の表面2a(重合部J2)に達するように、攪拌ピンF2の挿入深さを設定する。   In the friction stirring process in the fourth embodiment, as shown in FIG. 21, the stirring pin F <b> 2 rotated clockwise is inserted from the surface 4 a of the auxiliary member 4. In the fourth embodiment, the stirring pin F <b> 2 is inserted into the central portion of the auxiliary member 4 in the width direction. In the fourth embodiment, the insertion depth of the stirring pin F2 is set so that the stirring pin F2 reaches the surface 2a (the overlapping portion J2) of the base member 2.

第四実施形態では、ベース部材2、蓋板3及び補助部材4に攪拌ピンF2のみを挿入し、被接合金属部材と連結部F1とは離間させつつ移動させる。なお、第四実施形態における攪拌ピンF2の移動方向は、第一実施形態における攪拌ピンF2の移動方向と同じである(図3参照)。
そして、ベース部材2、蓋板3及び補助部材4と攪拌ピンF2とを接触させた状態で、凹溝12に沿って接合用回転ツールFを相対移動させる。これにより、ベース部材2、蓋板3及び補助部材4(重合部J2)は、凹溝12に沿って摩擦攪拌接合される。
In the fourth embodiment, only the stirring pin F2 is inserted into the base member 2, the lid plate 3, and the auxiliary member 4, and the metal member to be joined and the connecting portion F1 are moved while being separated from each other. In addition, the moving direction of the stirring pin F2 in 4th embodiment is the same as the moving direction of the stirring pin F2 in 1st embodiment (refer FIG. 3).
Then, with the base member 2, the cover plate 3, the auxiliary member 4, and the stirring pin F <b> 2 in contact, the bonding rotary tool F is relatively moved along the concave groove 12. As a result, the base member 2, the cover plate 3, and the auxiliary member 4 (overlapping portion J <b> 2) are friction stir welded along the concave groove 12.

第四実施形態における除去工程では、補助部材4を蓋板3から離間する方向に折り曲げて蓋板3から除去する。   In the removing step in the fourth embodiment, the auxiliary member 4 is bent away from the cover plate 3 and removed from the cover plate 3.

以上説明した第四実施形態に係る伝熱板1の製造方法によれば、図21に示すように、ベース部材2及び蓋板3に加え、補助部材4も同時に摩擦攪拌接合することにより、接合部の金属不足を防ぐことができる。これにより、蓋板3の表面3aに窪みができるのを防ぐことができるとともに、伝熱板1の水密性及び気密性を向上させることができる。
また、第四実施形態では、攪拌ピンF2を補助部材4の中央部に対して容易に挿入することができるとともに、攪拌ピンF2の両側に補助部材4を配置する分、接合部の金属不足をより確実に防ぐことができる。
According to the manufacturing method of the heat transfer plate 1 according to the fourth embodiment described above, as shown in FIG. 21, in addition to the base member 2 and the cover plate 3, the auxiliary member 4 is also joined by friction stir welding at the same time. It is possible to prevent a shortage of metal in the part. Thereby, while being able to prevent the surface 3a of the cover plate 3 from forming a dent, the water-tightness and airtightness of the heat exchanger plate 1 can be improved.
Further, in the fourth embodiment, the stirring pin F2 can be easily inserted into the central portion of the auxiliary member 4, and the auxiliary member 4 is disposed on both sides of the stirring pin F2. This can be prevented more reliably.

また、第四実施形態では、摩擦攪拌工程によって補助部材4にバリVが形成されるが、除去工程においてバリVを補助部材4ごと取り除くことができる。これにより、バリVを除去する作業を容易に行うことができる。   In the fourth embodiment, the burrs V are formed on the auxiliary member 4 by the friction stirring process. However, the burrs V can be removed together with the auxiliary member 4 in the removing process. Thereby, the operation | work which removes the burr | flash V can be performed easily.

(第四実施形態の第一変形例)
次に、第四実施形態に係る伝熱板1の製造方法の第一変形例について説明する。
第四実施形態の第一変形例では、図22に示すように、摩擦攪拌工程において、補助部材4の端面4cを通り、ベース部材2の表面2a及び蓋板3の表面3aに直交する基準線Xと、接合用回転ツールFの回転中心軸Cとが重なるように、攪拌ピンF2を相対移動させる。
また、第四実施形態の第一変形例では、摩擦攪拌接合で発生するバリVが補助部材4に形成されるように接合条件を設定する。このように、補助部材4側にバリVを集約させると、除去工程においてバリVを補助部材4ごと蓋板3から除去することができる。
(First modification of the fourth embodiment)
Next, the 1st modification of the manufacturing method of the heat exchanger plate 1 which concerns on 4th embodiment is demonstrated.
In the first modification of the fourth embodiment, as shown in FIG. 22, in the friction stirring step, the reference line passes through the end surface 4 c of the auxiliary member 4 and is orthogonal to the surface 2 a of the base member 2 and the surface 3 a of the lid plate 3. The stirring pin F2 is relatively moved so that X and the rotation center axis C of the welding rotary tool F overlap.
In the first modification of the fourth embodiment, the joining conditions are set so that the burrs V generated in the friction stir welding are formed on the auxiliary member 4. As described above, when the burrs V are gathered on the auxiliary member 4 side, the burrs V can be removed from the cover plate 3 together with the auxiliary members 4 in the removing step.

(第四実施形態の第二変形例)
次に、第四実施形態に係る伝熱板1の製造方法の第二変形例について説明する。
第四実施形態の第二変形例では、図23に示すように、摩擦攪拌工程において、摩擦攪拌後に、接合用回転ツールFの片側のみに補助部材4が残存する程度に、接合用回転ツールFの回転中心軸Cを基準線Xよりもわずかに補助部材4の中央側に偏移させて、攪拌ピンF2を相対移動させる。
このように、接合用回転ツールFの回転中心軸Cを補助部材4の端面4cよりもわずかに中央側に偏移させることで、接合部の金属不足をより確実に防ぐことができる。
また、第四実施形態の第二変形例では、摩擦攪拌接合で発生するバリVが補助部材4に形成されるように接合条件を設定する。このように、補助部材4側にバリVを集約させると、除去工程においてバリVを補助部材4ごと蓋板3から除去することができる。
(Second modification of the fourth embodiment)
Next, the 2nd modification of the manufacturing method of the heat exchanger plate 1 which concerns on 4th embodiment is demonstrated.
In the second modification of the fourth embodiment, as shown in FIG. 23, in the friction stirring step, after the friction stirring, the auxiliary rotating member F remains so that the auxiliary member 4 remains only on one side of the welding rotary tool F. The rotation center axis C is slightly shifted to the center side of the auxiliary member 4 with respect to the reference line X, and the stirring pin F2 is relatively moved.
In this manner, by shifting the rotation center axis C of the bonding rotary tool F slightly toward the center side from the end surface 4c of the auxiliary member 4, it is possible to more reliably prevent the metal shortage at the bonded portion.
In the second modification of the fourth embodiment, the joining conditions are set so that the burrs V generated in the friction stir welding are formed in the auxiliary member 4. As described above, when the burrs V are gathered on the auxiliary member 4 side, the burrs V can be removed from the cover plate 3 together with the auxiliary members 4 in the removing step.

以上、本発明に係る第四実施形態について説明したが、これに限定されるものではなく、第一実施形態と同様に、本発明の趣旨を逸脱しない範囲において、適宜変更が可能である。
例えば、第四実施形態では、図20に示すように、ベース部材2の凹溝12を覆うように蓋板3を配置しているが、ベース部材2の表面2aに窪んだ凹部を形成し、凹部を覆うように蓋板3を配置してもよい。この場合には、凹部を囲むように攪拌ピンを移動させ、凹部の周囲においてベース部材2、蓋板3及び補助部材4を摩擦攪拌接合する。
The fourth embodiment according to the present invention has been described above. However, the present invention is not limited to this, and can be modified as appropriate without departing from the spirit of the present invention, as in the first embodiment.
For example, in the fourth embodiment, as shown in FIG. 20, the cover plate 3 is disposed so as to cover the recessed groove 12 of the base member 2, but a recessed portion is formed in the surface 2 a of the base member 2, You may arrange | position the cover plate 3 so that a recessed part may be covered. In this case, the stirring pin is moved so as to surround the recess, and the base member 2, the cover plate 3 and the auxiliary member 4 are friction-stir welded around the recess.

また、第四実施形態では、図23に示すように、摩擦攪拌工程において、攪拌ピンF2がベース部材2の表面2a(重合部J2)に達するように設定しているが、攪拌ピンF2がベース部材2の表面2aに達していなくてもよい。つまり、蓋板3及び補助部材4のみに攪拌ピンF2を挿入して摩擦攪拌接合を行ってもよい。この場合には、攪拌ピンF2と蓋板3との摩擦熱により、重合部J2が塑性流動化して接合される。   Further, in the fourth embodiment, as shown in FIG. 23, in the friction stirring step, the stirring pin F2 is set so as to reach the surface 2a (the overlapping portion J2) of the base member 2, but the stirring pin F2 is the base. The surface 2a of the member 2 may not be reached. That is, the friction stir welding may be performed by inserting the stirring pin F2 only into the cover plate 3 and the auxiliary member 4. In this case, the overlapping portion J2 is plastically fluidized and joined by frictional heat between the stirring pin F2 and the cover plate 3.

[第五実施形態]
次に、本発明の第五実施形態に係る伝熱板1の製造方法について説明する。
第五実施形態に係る伝熱板1の製造方法は、図26に示すように、ベース部材2の裏面2bに面接触するように補助部材4を配置し、接合用回転ツールFの攪拌ピンF2を補助部材4の裏面4b側から挿入する点で第四実施形態と相違する。第五実施形態に係る伝熱板1の製造方法では、第四実施形態と相違する部分を中心に説明する。
[Fifth embodiment]
Next, the manufacturing method of the heat exchanger plate 1 which concerns on 5th embodiment of this invention is demonstrated.
As shown in FIG. 26, in the method of manufacturing the heat transfer plate 1 according to the fifth embodiment, the auxiliary member 4 is disposed so as to be in surface contact with the back surface 2b of the base member 2, and the stirring pin F2 of the rotating tool F for joining is used. Is different from the fourth embodiment in that it is inserted from the back surface 4b side of the auxiliary member 4. In the method for manufacturing the heat transfer plate 1 according to the fifth embodiment, a description will be given focusing on portions that are different from the fourth embodiment.

第五実施形態における閉塞工程では、図24に示すように、凹溝12を覆うように、ベース部材2の表面2aに一枚の蓋板3を重ね合わせる。これにより、重合部J2が形成される。
第五実施形態における配置工程では、図25に示すように、閉塞工程後のベース部材2及び蓋板3を上下方向にひっくり返す。このように、ベース部材2及び蓋板3を上下反転させることで、ベース部材2の裏面2bが上側に配置される。
そして、ベース部材2の裏面2bに面接触するように補助部材4を配置し、ベース部材2の裏面2bに補助部材4の表面4aを重ね合わせる。第五実施形態では、凹溝12の幅方向の中央部の両側に二枚の補助部材4を配置する。
In the closing process in the fifth embodiment, as shown in FIG. 24, a single cover plate 3 is overlaid on the surface 2 a of the base member 2 so as to cover the concave groove 12. Thereby, the superposition | polymerization part J2 is formed.
In the arrangement process in the fifth embodiment, as shown in FIG. 25, the base member 2 and the cover plate 3 after the closing process are turned upside down. Thus, the back surface 2b of the base member 2 is arranged on the upper side by turning the base member 2 and the cover plate 3 upside down.
Then, the auxiliary member 4 is disposed so as to be in surface contact with the back surface 2 b of the base member 2, and the front surface 4 a of the auxiliary member 4 is overlapped with the back surface 2 b of the base member 2. In the fifth embodiment, two auxiliary members 4 are arranged on both sides of the central portion in the width direction of the groove 12.

第五実施形態における摩擦攪拌工程では、図26に示すように、ベース部材2の裏面2b側から接合用回転ツールFによってベース部材2及び蓋板3を摩擦攪拌によって接合する。
第五実施形態では、接合用回転ツールFを左回転させており、攪拌ピンF2の螺旋溝は基端から先端に向かうにつれて右回りに形成されている。
In the friction stirring step in the fifth embodiment, as shown in FIG. 26, the base member 2 and the cover plate 3 are joined by friction stirring from the back surface 2b side of the base member 2 by the joining rotary tool F.
In the fifth embodiment, the joining rotary tool F is rotated counterclockwise, and the spiral groove of the stirring pin F2 is formed clockwise as it goes from the proximal end to the distal end.

第五実施形態における摩擦攪拌工程では、左回転させた攪拌ピンF2を補助部材4の裏面2bから挿入する。攪拌ピンF2は、凹溝12の側方で補助部材4の中央部に挿入する。また、攪拌ピンF2がベース部材2を貫通して蓋板3の裏面3b(重合部J2)に達するように攪拌ピンF2の挿入深さを設定する。
第五実施形態では、被接合金属部材(ベース部材2、蓋板3及び補助部材4)に攪拌ピンF2のみを挿入し、被接合金属部材と連結部F1とは離間させつつ移動させる。言い換えると、攪拌ピンF2の基端部は露出させた状態で摩擦攪拌接合を行う。なお、第五実施形態における攪拌ピンF2の移動方向は、第一実施形態における攪拌ピンF2の移動方向と同じである(図3参照)。
In the friction stirring step in the fifth embodiment, the stirring pin F2 rotated counterclockwise is inserted from the back surface 2b of the auxiliary member 4. The stirring pin F <b> 2 is inserted into the central portion of the auxiliary member 4 on the side of the concave groove 12. Further, the insertion depth of the stirring pin F2 is set so that the stirring pin F2 passes through the base member 2 and reaches the back surface 3b (overlapping portion J2) of the lid plate 3.
In the fifth embodiment, only the stirring pin F2 is inserted into the metal member to be bonded (base member 2, lid plate 3 and auxiliary member 4), and the metal member to be bonded and the connecting portion F1 are moved while being separated from each other. In other words, the friction stir welding is performed with the base end portion of the stirring pin F2 exposed. In addition, the moving direction of the stirring pin F2 in 5th embodiment is the same as the moving direction of the stirring pin F2 in 1st embodiment (refer FIG. 3).

そして、ベース部材2、蓋板3及び補助部材4と攪拌ピンF2とを接触させた状態で、凹溝12に沿って接合用回転ツールFを相対移動させる。これにより、ベース部材2、蓋板3及び補助部材4が摩擦攪拌接合される。   Then, with the base member 2, the cover plate 3, the auxiliary member 4, and the stirring pin F <b> 2 in contact, the bonding rotary tool F is relatively moved along the concave groove 12. Thereby, the base member 2, the cover plate 3, and the auxiliary member 4 are friction stir welded.

なお、第五実施形態では、被接合金属部材に対する攪拌ピンF2の挿入深さが大きく、接合用回転ツールFの回転速度を高めることが難しい。したがって、第五実施形態では、接合用回転ツールFが低速回転しているため、バリVはフロー側に比べてシアー側の方に多く発生する傾向にある。
第五実施形態における除去工程では、バリVを補助部材4ごとベース部材2の裏面2bから除去することができる。
In the fifth embodiment, the insertion depth of the stirring pin F2 with respect to the metal member to be joined is large, and it is difficult to increase the rotational speed of the joining rotary tool F. Therefore, in the fifth embodiment, since the joining rotary tool F rotates at a low speed, the burrs V tend to be generated more on the shear side than on the flow side.
In the removing step in the fifth embodiment, the burr V can be removed together with the auxiliary member 4 from the back surface 2b of the base member 2.

以上説明した第五実施形態に係る伝熱板1の製造方法によれば、図26に示すように、ベース部材2及び蓋板3に加え、補助部材4も同時に摩擦攪拌接合することにより、接合部の金属不足を防ぐことができる。これにより、伝熱板1の水密性及び気密性を向上させることができる。
第五実施形態における摩擦攪拌工程では、ベース部材2の裏面2b側から攪拌ピンF2を挿入しており、蓋板3の表面3aに塑性化領域が露出しないため、伝熱板1の外観を良くすることができる。
第五実施形態における摩擦攪拌工程では、補助部材4の中央部に対して攪拌ピンF2を容易に挿入することができるとともに、攪拌ピンF2の両側に補助部材4を配置する分、接合部の金属不足をより確実に防ぐことができる。
According to the manufacturing method of the heat transfer plate 1 according to the fifth embodiment described above, as shown in FIG. 26, in addition to the base member 2 and the cover plate 3, the auxiliary member 4 is also joined by friction stir welding at the same time. It is possible to prevent a shortage of metal in the part. Thereby, the watertightness and airtightness of the heat exchanger plate 1 can be improved.
In the friction stirring step in the fifth embodiment, the stirring pin F2 is inserted from the back surface 2b side of the base member 2, and the plasticized region is not exposed on the surface 3a of the cover plate 3, so that the appearance of the heat transfer plate 1 is improved. can do.
