Abstract
Description
本発明は部材の接合装置及び接合方法並びに接合体の製造方法に関し、特に摩擦熱を利用した接合に係る。 The present invention relates to a joining apparatus and joining method for members, and a method for producing a joined body, and particularly relates to joining using frictional heat.
金属材料の接合にはアーク溶接に代表されるようにアーク放電等の熱源を利用し、接合部を溶接接合する溶接が一般的であり、樹脂材料の接合には接着剤を用いる接着の他に熱風等の熱源を利用した溶着等が一般的である。
しかし、これらは外部からの熱源を利用したものでありエネルギー消費量が大きく、またアーク溶接においては溶接棒、フラックス、シールドガス等が必要であったり、ヒューム等の環境対策も必要であった。
For joining metal materials, it is common to use a heat source such as arc discharge as represented by arc welding, and welding to join the joints by welding. Generally, welding using a heat source such as hot air is used.
However, these use an external heat source, which consumes a large amount of energy, and arc welding requires welding rods, flux, shielding gas, etc., and environmental measures such as fume.
そこで、自己発熱を利用した摩擦圧接や摩擦撹拌接合が提案されている。
摩擦圧接は接合する部材の接合面同士を高速で擦り合せることで摩擦熱を発生させ、擦り合せの急停止とほぼ同時にアプセット圧を加えるものである。
よって、従来の摩擦圧接は被接合材間の少なくとも一方を高速で擦り合せる手段、それを急停止する手段、アプセット加圧する手段等、装置の構造が複雑で品質管理が難しかった。
また、摩擦圧接は被接合材が棒材等の回転可能な材料に適するものの板材の接合には不向きであった。
また、異なる材料からなる被接合材の接合も、材料の特性の相違により困難であった。
摩擦撹拌接合は、回転する工具の突起部を用いて被接合材の接合部を加熱し、材料内部に生ずる塑性流動により接合するものであるが、塑性流動の不均一による内部欠陥が発生しやすい課題があった。
Therefore, friction welding and friction stir welding using self-heating have been proposed.
In friction welding, frictional heat is generated by rubbing the joining surfaces of members to be joined at high speed, and an upset pressure is applied almost simultaneously with the sudden stop of rubbing.
Therefore, in the conventional friction welding, the structure of the apparatus is complicated and quality control is difficult, such as a means for rubbing at least one of the materials to be joined at high speed, a means for suddenly stopping it, and a means for upsetting.
Further, the friction welding is not suitable for joining plate materials although the material to be joined is suitable for a rotatable material such as a bar material.
Also, joining of materials to be joined made of different materials has been difficult due to the difference in material characteristics.
Friction stir welding is a method in which a joint of a material to be joined is heated by using a protrusion of a rotating tool and joined by plastic flow generated inside the material. However, internal defects due to non-uniform plastic flow are likely to occur. There was a problem.
特許文献１には、同公報図２に示すように、棒材Ｂ１、Ｂ２の断面より大きいディスクの中心部から離れた部分を、このＢ１、Ｂ２の間に挟み込み回転させることで摩擦熱を発生させ、その後にこのディスクを抽出し、棒材Ｂ１、Ｂ２を圧接する技術を開示する。
しかし、同公報に開示する技術は、ディスクを抽出後に棒材Ｂ１、Ｂ２を圧接する２工程からなるバッチ処理であるだけでなく、棒材の接合面全体にディスクが接触していなければならず、棒材の接合に適していても板材には不向きである。
In Patent Document 1, as shown in FIG. 2, friction heat is generated by sandwiching and rotating a portion of the disc larger than the cross section of the bars B1 and B2 from the center of the disc between B1 and B2. Then, this disk is extracted, and a technique for press-contacting the bars B1 and B2 is disclosed.
However, the technique disclosed in the publication is not only a batch process consisting of two steps of pressing the bars B1 and B2 after extracting the disk, but the disk must be in contact with the entire joining surface of the bars. Even though it is suitable for joining bars, it is not suitable for plate materials.
本発明は、構造が簡単で摩擦熱により連続的に接合でき、且つ接合品質に優れる接合装置及びそれを用いた接合方法の提供を目的とする。 An object of the present invention is to provide a joining device that has a simple structure, can be joined continuously by frictional heat, and has excellent joining quality, and a joining method using the joining device.
本発明に係る接合装置は、可動接合工具と、前記可動接合工具の両側にそれぞれ被接合材を保持固定するための一対の第１固定具及び第２固定具を備え、前記可動接合工具が前記両側の被接合材の間に沿って移動するための移動機構を有し、前記第１固定具及び第２固定具は、それぞれ保持固定した被接合材が前記可動接合工具に向けて加圧及び相互に押圧接触制御する加圧制御機構を有することを特徴とする。 A joining apparatus according to the present invention includes a movable joining tool and a pair of first and second fixing tools for holding and fixing a material to be joined to both sides of the movable joining tool. The first fixing tool and the second fixing tool each have a moving mechanism for moving between the materials to be joined on both sides, and the materials to be joined held and fixed are pressed against the movable joining tool. It has a pressurizing control mechanism for controlling the pressing contact with each other.
ここで可動接合工具は、被接合材の接合面と擦り合せ摩擦熱を発生させるための工具をいい、回転運動する回転体や往復運動する帯状体等が例として挙げられる。
当該可動接合工具と被接合材の接合面との擦り合せにより発生した摩擦熱により、当該被接合材の接合面が部分的に溶融、又は、溶融しないまでも当該摩擦熱により固相拡散が促進され、当該接合面を介して当該被接合材を接合することができる。
Here, the movable joining tool refers to a tool for generating frictional heat by rubbing with the joining surface of the materials to be joined, and examples thereof include a rotating body that rotates and a belt-like body that reciprocates.
Friction heat generated by rubbing the movable joining tool and the joining surface of the material to be joined causes the solid surface diffusion to be accelerated by the frictional heat even if the joining surface of the material to be joined is partially melted or not melted. And the said to-be-joined material can be joined via the said joint surface.
ここで加圧制御機構は、それぞれ保持固定した被接合材が前記可動接合工具に向けて加圧及び相互に押圧接触制御される機構である。
加圧制御機構の加圧原理は限定されるものではない。
例えば、液体又は気体を圧力媒体としてシリンダーにより加圧する機構であっても、モーター等を利用した電動によって加圧する機構であってもよい。
加圧制御機構は、この加圧機構に加圧力を制御する機能を付加したものである。
第１固定具及び第２固定具にシリンダーを接続して加圧することもできるし、スライド機構を介して加圧することもできる。
Here, the pressurization control mechanism is a mechanism in which the materials to be joined that are held and fixed are pressed and controlled to be pressed against each other toward the movable joining tool.
The pressurization principle of the pressurization control mechanism is not limited.
For example, it may be a mechanism that pressurizes a liquid or gas using a cylinder as a pressure medium, or a mechanism that pressurizes by electric power using a motor or the like.
The pressurization control mechanism is obtained by adding a function of controlling the pressurizing force to the pressurization mechanism.
A cylinder can be connected to the first fixture and the second fixture to pressurize them, or pressure can be applied via a slide mechanism.
本発明に係る接合方法は、前記加圧制御機構によりそれぞれ第１被接合材及び第２被接合材を可動接合具の両側に圧接させた状態で前記可動接合工具を前記被接合材に対して相対可動させることで、前記第１及び第２被接合材の端面を摩擦加熱しながら、又はその後に、前記可動接合工具を前記第１及び第２被接合材の間に沿って前記移動機構にて通過させることで、前記可動接合工具が通過した部分の前記第１及び第２被接合材が接合されることを特徴する。
これにより、第１被接合材と第２被接合材とが接合された接合体が製造される。
例えば、板材を接合する場合に接合長さが比較的短い板材であれば、摩擦加熱により接合面を溶融し、その後に可動接合工具を移動通過させて相互に接触加圧してもよい。
板材の接合長さが相対的に長い場合は接合材の端面を摩擦加熱しながら可動接合工具を移動させることで、この可動接合工具にて順次接合面を加熱しつつ、通過した部位を連続的に接合することができる。
本発明において、第１被接合材と第２被接合材は同じ材質の場合のみならず、前記第１被接合材と第２被接合材とは異なる材質からなる材料であってもよい。
第１被接合材と第２被接合材とが異なる材料の場合は、それぞれ最適な摩擦加熱が得られるように可動接合工具の両面の摩擦係数が相互に異なるようにすることができる。
In the joining method according to the present invention, the movable joining tool is brought into contact with the material to be joined in a state in which the first material to be joined and the second material to be joined are brought into pressure contact with both sides of the movable joint by the pressure control mechanism. By relatively moving the end surfaces of the first and second workpieces to be frictionally heated, or after that, the movable joining tool is moved between the first and second workpieces to the moving mechanism. The first and second materials to be joined in the portion through which the movable joining tool has passed are joined.
Thereby, the joined body by which the 1st to-be-joined material and the 2nd to-be-joined material were joined is manufactured.
For example, in the case of joining plate materials, if the plate length is relatively short, the joining surface may be melted by friction heating, and then the movable joining tool may be moved and passed to contact and press each other.
When the joining length of the plate is relatively long, the movable joining tool is moved while frictionally heating the end face of the joining material, so that the joining surface is continuously heated by this movable joining tool and the passing part is continuously Can be joined.
In the present invention, the first material to be joined and the second material to be joined are not limited to the same material, and the first material to be joined and the second material to be joined may be made of different materials.
When the first material to be joined and the second material to be joined are different materials, the friction coefficients on both surfaces of the movable joining tool can be made different from each other so that optimum frictional heating can be obtained.
本発明に係る接合方法は上記のように可動接合工具の両面に向けて第１被接合材と第２被接合材を押圧し、可動接合工具の被接合材との擦り合せにより摩擦熱を発生させながら、あるいはその後に、この第１及び第２被接合材の間に沿って可動接合工具を移動させると、この可動接合工具が通過した部分の第１及び第２被接合材は相互に加圧接触し、連続的に接合される。
可動接合工具は、被接合材の接合面全体に摩擦接触し、この接合面の不活性膜を除去するドレッシング作用を有するのが好ましい。
また、連続的な接合を考慮すると可動接合工具は厚みが薄い方が好ましいが、擦り合せ可動時の剛性が要求される。
即ち、可動接合工具は両側の表面が平行な厚みの薄い円盤形状の回転体や、移動方向とは直交方向に往復運動する厚みの薄いプレート体にできると接合面全体にドレッシング作用を付与しやすく好ましいが現実的に剛性を確保しつつ、可動接合工具の通過により連続的に接合を可能にするには、可動接合工具の被接合材との接触部の厚みが１０ｍｍ以下の範囲にて、ある程度の厚みを持たせつつ、周縁部を先端部に向けて徐々に薄くさせるのがよい。
この場合に両面が徐々に薄くなる両面の交差角θが３０°以下、好ましくは１０°以下の範囲であるのがよい。
このようにすると接合面の均一な摩擦加熱と、その後の連続的な接合が容易となる。
As described above, the joining method according to the present invention presses the first material to be joined and the second material to be joined toward both surfaces of the movable joining tool, and generates frictional heat by rubbing with the material to be joined of the movable joining tool. Or after that, when the movable joining tool is moved between the first and second workpieces, the first and second workpieces through which the movable joining tool passes are mutually added. Pressure contact and continuous joining.
The movable joining tool preferably has a dressing action that makes frictional contact with the entire joining surface of the material to be joined and removes the inactive film on the joining surface.
In consideration of continuous joining, it is preferable that the movable joining tool is thin. However, rigidity when moving by rubbing is required.
In other words, if the movable joining tool can be made into a thin disk-shaped rotating body whose surfaces on both sides are parallel or a thin plate body that reciprocates in the direction perpendicular to the moving direction, it is easy to give a dressing action to the entire joining surface. In order to enable continuous joining by passing through the movable joining tool while preferably securing rigidity, it is preferable that the thickness of the contact portion of the movable joining tool with the material to be joined is within a range of 10 mm or less. It is preferable that the peripheral edge part is gradually made thinner toward the tip part while keeping the thickness of.
In this case, the crossing angle θ between the two surfaces where the both surfaces gradually become thin is 30 ° or less, preferably 10 ° or less.
If it does in this way, uniform friction heating of a joint surface and subsequent continuous joining will become easy.
本発明に係る接合装置を用いると、接合に必要な熱エネルギーを可動接合工具とその両側に配した２枚の被接合材との間の摩擦熱により得るとともに、この可動接合工具を通過させ、接合界面に垂直な荷重を負荷して、摩擦熱により一部軟化した被接合材同士を密着させて接合することができる。
本発明による接合法は摩擦現象を利用した自己発熱型であるため、アーク溶接法に比べて、接合に要するエネルギーが少ない。
また、スパッタやヒュームといった有害物質の発生がない。
さらには、異なる材質の材料を接合する場合には、両材料の融点や高温変形挙動などの相違などに基づいて、可動接合工具の両面の摩擦係数が異なるように材料を貼り合せたり相互に異なる表面処理を施すことにより、両材料にそれぞれ適切な摩擦熱を加え、それぞれの材料にとって好ましい条件で接触、加圧することによって接合を可能にすることもできる。
When using the joining apparatus according to the present invention, the thermal energy necessary for joining is obtained by frictional heat between the movable joining tool and the two materials to be joined disposed on both sides thereof, and this movable joining tool is passed through, By applying a load perpendicular to the joining interface, the materials to be joined partially softened by frictional heat can be brought into close contact and joined.
Since the joining method according to the present invention is a self-heating type utilizing a friction phenomenon, the energy required for joining is less than that of the arc welding method.
In addition, no harmful substances such as spatter and fumes are generated.
Furthermore, when materials of different materials are to be joined, the materials are bonded to each other or different from each other so that the friction coefficients on both sides of the movable joining tool are different based on differences in the melting point and high temperature deformation behavior of both materials. By applying a surface treatment, it is possible to apply a suitable frictional heat to both materials, and to make the bonding possible by contact and pressurization under conditions favorable for the respective materials.
本発明に係る接合方法は、模式図を図１に示すように接合に必要な熱エネルギーを可動接合工具Ｔとその両側に配した２枚の被接合材Ｗ１、Ｗ２との間の擦り合せによる摩擦熱にて得るとともに、この可動接合工具を被接合材Ｗ１、Ｗ２の間に沿って移動させることで連続的に接合界面に垂直な荷重を負荷して、摩擦熱により一部軟化した被接合材同士を密着させて接合するものである。
２枚の被接合材Ｗ１、Ｗ２は便宜上、第１被接合材、第２被接合材とそれぞれ称する。
図１に示した実施例は、可動接合工具が回転する円盤であり、材料が接触する部分の円盤の厚さｔが１０ｍｍ以下であり、さらに円盤の縁に近づくにしたがって厚さが薄くなっている。
理想的には薄くて両面が平行な円盤であるが現実的に材料の剛性を確保するには、このような形状がよい。
この形状によって形成される二枚の面の交差する交差角度θは、３０°以下であることが好ましい。
より好ましくは、１０°以下の１〜１０°の範囲である。
ここでいう交差角度とは、被接合材と接触する円盤の面における平均的な角度を意味する。
したがって、最先端まで真に鋭利な角度を有する必要はない。
たとえば、極先端は丸みを帯びた断面形状であってもよい。
可動接合工具は、このような円盤形状以外に、一定方向に連続して移動する、又は、往復運動する帯状の形態であってもよい。
帯状の可動接合工具であっても、円盤形状と同様の理由により、材料が接触する部分の厚さが１０ｍｍ以下であり、さらに片側の縁に近づくにしたがって厚さが薄くなる形状が好ましく、交差角度θは３０°以下である。
可動接合工具の材質は、被接合材を考慮して任意に選択することができる。
一般には、ある程度の硬度と靭性を兼ね備えた材質が好ましい。
必要に応じて、可動接合工具の表面に処理を施してもよい。
表面処理方法は、問わない。
表面に摩擦係数の異なる材料を貼り合せてもよい。
In the joining method according to the present invention, as shown in a schematic diagram of FIG. 1, the thermal energy necessary for joining is rubbed between the movable joining tool T and the two workpieces W 1 and W 2 arranged on both sides thereof. In addition to the frictional heat generated by the alignment, this movable joining tool is moved along the workpieces W 1 and W 2 so that a load perpendicular to the joining interface is continuously applied, and the frictional heat partially The softened materials to be joined are brought into close contact with each other and joined.
The two materials to be bonded W1 and W2 are referred to as a first material to be bonded and a second material to be bonded for convenience.
The embodiment shown in FIG. 1 is a disk in which the movable joining tool rotates, and the thickness t of the disk in contact with the material is 10 mm or less, and the thickness becomes thinner as it approaches the edge of the disk. Yes.
The disk is ideally thin and parallel on both sides, but such a shape is good for practically securing the rigidity of the material.
The intersecting angle θ between two surfaces formed by this shape is preferably 30 ° or less.
More preferably, it is the range of 1-10 degrees of 10 degrees or less.
The crossing angle here means an average angle on the surface of the disk in contact with the material to be joined.
Therefore, it is not necessary to have a truly sharp angle to the forefront.
For example, the pole tip may have a rounded cross-sectional shape.
In addition to such a disk shape, the movable joining tool may be in the form of a band that continuously moves in a certain direction or reciprocates.
Even in the case of a strip-shaped movable joining tool, for the same reason as the disk shape, the thickness of the portion in contact with the material is preferably 10 mm or less, and further the shape becomes thinner as it approaches the edge on one side, The angle θ is 30 ° or less.
The material of the movable joining tool can be arbitrarily selected in consideration of the material to be joined.
In general, a material having a certain degree of hardness and toughness is preferable.
You may process to the surface of a movable joining tool as needed.
The surface treatment method does not matter.
Materials having different friction coefficients may be bonded to the surface.
図２に本発明に係る接合装置の構成例を示す。
モーター３０等の駆動源の主軸３１にディスク状の可動接合工具Ｔを装着してある。
この可動接合工具Ｔの両側に第１及び第２被接合材Ｗ１、Ｗ２を配置するために、第１固定具１１、第２固定具２１を有する。
このそれぞれの固定具は第１加圧制御機構１２、第２加圧制御機構２２により加圧制御されている。
本実施例は、加圧制御機構としてスライド制御機構を用いた例である。
スライダー１２ａ、２２ａをシリンダー１２ｂ、２２ｂに連結してあり、このスライダーに第１及び第２固定具をそれぞれ取り付けた。
また、モーター３０はベース部３２を介して紙面前後方向に移動可能な移動機構４０を有する。
図２に示した実施例では、回転盤４２に連結したおねじ杵４１をハンドル４３にて回動すると、それによりおねじ杵４１に螺合したベース部３２が第１及び第２被接合材Ｗ１、Ｗ２の間に沿って移動する。
図２に示した接合装置は、実験機として製作した例である。
第１、第２固定具１１、２１及び第１、第２加圧制御機構１２、２２の構造は、可動接合工具Ｔの両側に一対の被接合材を保持でき、この可動接合工具Ｔの両側に向けてそれぞれ押圧でき、且つ第１及び第２被接合材の間を、この可動接合工具Ｔが通過すると、そのまま連続的に第１及び第２被接合材の接合面を相互に圧接できれば、装置の構造そのものに制限はない。
ここで、接合面に摩擦熱を発生させるための摩擦押圧力と、第１及び第２被接合材を相互に圧接する接合押圧力を、一体的に制御しても、それぞれ制御できるようにしてもよい。
本発明に係る接合方法は板材の接合に限定されないが、板材に好適である。
接合長さが比較的短い板材にあっては、上記摩擦押圧力を付加後に可動接合工具を移動及び被接合材を通過させた後に接合押圧力を付加してもよいが、接合長さが長くなる程、摩擦加熱時間と接合時間に時間差が生ずることから摩擦押圧力と接合押圧力とをそれぞれ制御できるようにすると、摩擦加熱と接合とを連続的に実施制御しやすい。
移動機構４０についても本実施例に限定されず移動量を自動制御できるようにしてもよい。
接合面は可動接合工具Ｔによりドレッシングされるが、その活性面を維持しやすいように可動接合工具Ｔの接触面に不活性ガスをシールドガスとして吹き付けてもよく、装置全体を不活性雰囲下に設定してもよい。
（実施例１）
FIG. 2 shows a configuration example of the joining apparatus according to the present invention.
A disc-shaped movable joining tool T is mounted on a
In order to arrange the first and second workpieces W 1 and W 2 on both sides of the movable joining tool T, a first fixture 11 and a second fixture 21 are provided.
The respective fixtures are pressure controlled by the first pressure control mechanism 12 and the second pressure control mechanism 22.
In the present embodiment, a slide control mechanism is used as the pressurization control mechanism.
Further, the
In the embodiment shown in FIG. 2, when the
The joining apparatus shown in FIG. 2 is an example manufactured as an experimental machine.
The structures of the first and second fixtures 11 and 21 and the first and second pressure control mechanisms 12 and 22 can hold a pair of workpieces on both sides of the movable joining tool T, and both sides of the movable joining tool T. If the movable joining tool T passes between the first and second workpieces and can continuously press the joint surfaces of the first and second workpieces as they are, There is no limit to the structure of the device itself.
Here, the frictional pressing force for generating frictional heat on the bonding surface and the bonding pressing force for pressing the first and second workpieces together can be controlled even if they are integrally controlled. Also good.
The joining method according to the present invention is not limited to joining plate members, but is suitable for plate members.
For plate materials having a relatively short joining length, the joining pressing force may be applied after moving the movable joining tool after passing the frictional pressing force and passing the material to be joined, but the joining length is long. As shown, since there is a time difference between the friction heating time and the joining time, if the friction pressing force and the joining pressing force can be controlled, it is easy to continuously control the friction heating and the joining.
The movement mechanism 40 is not limited to this embodiment, and the movement amount may be automatically controlled.
Although the joining surface is dressed by the movable joining tool T, an inert gas may be sprayed as a shielding gas on the contact surface of the movable joining tool T so that the active surface can be easily maintained, and the entire apparatus is in an inert atmosphere. May be set.
