Description

【0001】
【発明の属する技術分野】
本発明は、糸はんだをリング状に成形加工するはんだ成形機に関するものである。
【0002】
【従来の技術】
大小の異径パイプの嵌合部をリング状の糸はんだでロー付けする工程は図5で示すように、予め成形したリング状の糸はんだ4aを小径パイプ7の端部外周面に装着する工程(A)と、小径パイプ7を大径パイプ6に嵌合する工程(B)及び(C)と、リング状の糸はんだ4aの周囲に高周波コイル8を配置させリング状の糸はんだ4aを溶解する工程(D)からなる。この(D)工程で溶解したリング状の糸はんだ4aは、大径パイプ6と小径パイプ7との嵌合外部に肉盛りされ、大径パイプ6と小径パイプ7のクリアランスに毛細現象で溶けたはんだが滲透して(E)で示すように、ロー付け4bを完了する。
【0003】
従来、前記リング状の糸はんだ4aの製造は図6で示すように、ボビン3に巻き取られている糸はんだ4をモータ1によって回転する軸2によってスパイラル状に巻回し、軸2に沿ってトラバースするカッター5により軸2の1回転毎に切断していた。
【0004】
【発明が解決しようとする課題】
上記従来の製造では、スパイラル状の糸はんだを切断するため、図7で示すように切断後の両端末5が食い違った形態となり、両端末が一致したリングが得られない。両端末5が食い違った形態ではパイプへの嵌合に影響し、また、大径パイプ6と小径パイプ7との嵌合部のロー付けの均等性に影響する。
【0005】
そこで、従来では前記切断後に成形型で両端末5が一致するよう修正加工を施していた。従って、コスト高になっていると共に、修正加工したリング状の糸はんだ4aを手作業でパイプに嵌装するため、作業の能率性にも問題があった。
【0006】
本発明の目的は、糸はんだを直接被加工物の外形に倣って巻回成形するようにしたはんだ成形機を提供することである。
【0007】
【課題を解決するための手段】
上記の目的を達成するための本発明の要旨は、糸はんだの送り装置と、上面に糸はんだの受け面を有し、対向する面に凹溝による曲げ型が形成され、アクチュエータによって前記対向する面が接近及び所定の間隔で離間する左右一対の駒と、前記送り装置によって送られてくる糸はんだの端末を規制するストッパと、前記ストッパで規制された糸はんだを所定の長さで切断するカッターと、被加工物を前記糸はんだの軸線と直交してクランプし、前記駒の対向する面の間において切断した糸はんだの上方から前記被加工物を前記曲げ型位置に昇降動するクランプ装置とを備え、前記被加工物の下降により前記切断した糸はんだを被加工物で引っ掛けて前記曲げ型位置に下降させ、駒の接近作動によって糸はんだを曲げ型により被加工物の外周面に巻回成形するようにしたものである。
【0008】
【発明の実施の形態】
以下本発明の実施の形態を図面に基づいて説明する。図1及び図2において、10はベース、11は前記ベース10上に直立している竪壁である。この竪壁11には糸はんだ4を巻き取ったボビン3が回転可能に軸支され、このボビン3から捲戻した糸はんだ4を一定の方向に送る送り装置12が設けられている。前記送り装置12はモータ12aによって回転する一対のローラ12bである。
【0009】
前記ボビン3の軸支位置とは反対のベース10上には支持台13が固設されており、この支持台13上に左右一対の駒15a,15bが設けられている。この左右一対の駒15a,15bは、上面に糸はんだ4の受け面28を有し、対向する面に凹溝による曲げ型21a,21bが形成され、アクチュエータ14によって前記対向する面が接近及び所定の間隔で離間するようになっている。
【0010】
前記一方の駒15aには前記送り装置12で送られる糸はんだ4のガイド18と後述するカッター16の進入隙間19とが設けられている。また、他方の駒15bには送り装置12によって送られてくる糸はんだ4の端末を規制するストッパボルト20が設けられている。
【0011】
前記一方の駒15aの上方にはアクチュエータ17によって昇降動するカッター16が配置されている。このカッター16は、前記ストッパボルト20で規制された糸はんだ4を所定の長さで切断するものである。
【0012】
さらに、クランプ装置23が前記駒15a,15bに併設されている。このクランプ装置23は糸はんだ4を装着する被加工物22をクランプして昇降動するものである。その構造は図3で示すように、シリンダ24で昇降動するテーブル25と、シリンダ26で前記テーブル25に対し昇降動するクランパ27とから構成されており、テーブル25上に載置した被加工物22をクランパ27によって押え込むものである。
【0013】
前記テーブル25上の被加工物22は、前記駒15a,15b上に送られてくる糸はんだ4の軸線と直交する軸線方向でクランプされ、クランプ装置23は、前記駒15a,15bの対向する面の間において前記被加工物22を駒15a,15b上の糸はんだ4の上方から前記曲げ型21a,21bに位置させるよう昇降動する。
【0014】
図例では被加工物22は円形のパイプであり、駒15a,15bの対向する面に設けられている曲げ型21a,21bは前記パイプの外形に対応した半円の凹溝によるものであるが、楕円形、三角、四角その他の外形でもよく、曲げ型21a,21bは、被加工物の外形に対応した形状とする。
【0015】
上記の構成による本発明の動作について説明する。ボビン3から巻き戻された糸はんだ4は送り装置12のローラ12bによって駒15a,15bの方向に送られ、左右に離間している一方の駒15aのガイド18を貫通して他方の駒15bのストッパボルト20に糸はんだ4の端末が当接規制され駒15a,15bの間の糸はんだ4は駒15a,15bのそれぞれに設けられている受け面28に支持される。このときクランプ装置23にクランプした被加工物22は、前記駒15a,15b上に送られてくる糸はんだ4の上方に上昇位置している。
【0016】
前記糸はんだ4の端末がストッパボルト20に当接規制された後には送り装置12のモータ12aが停止し、アクチュエータ17によってカッター16が作動して駒15a,15bの受け面28に支持されている糸はんだ4を切断する。
【0017】
この切断長さは、前記ストッパボルト20で規制されている糸はんだ4の端末からカッター16による切断長さであり、この長さは被加工物22の円周長と略等長である。
【0018】
前記糸はんだ4の切断後にはクランプ装置23が下降作動する。このクランプ装置23の下降作動によりクランプされている被加工物22は切断された糸はんだ4の上方から下降し、図4で示すように、駒15a,15b上の切断されている糸はんだ4を引っ掛けて曲げ型21a,21bに位置させる。
【0019】
前記被加工物22により引っ掛けて下降する際に糸はんだ4は左右に離間している駒15a,15bの対向する面間GでU字状の予備曲げされる。従って、前記駒15a,15bの対向する面間Gの間隔は被加工物22の直径と糸はんだ4の直径の2倍相当の寸法とすることが望ましい。
【0020】
前記糸はんだ4を被加工物22で引っ掛けて曲げ型21a,21bに位置した後は、アクチュエータ14によって駒15a,15bを、その対向する面が互いに接近するよう作動させる。
【0021】
前記駒15a,15bの対向する面が互いに接近することにより、被加工物22に引っ掛けられ、既に被加工物22の外周の半周をU字状に予備曲げされている糸はんだ4は曲げ型21a,21bによって被加工物22の外周面に沿って外周面の一周で巻回される。
【0022】
前記被加工物22の外周面の一周で巻回された糸はんだ4の両端末は、前記切断長さと曲げ型21a,21bとによってずれのない一致した突き合わせで成形される。
【0023】
例えば、被加工物22の端末の位置と糸はんだ4を巻回する位置が合うように被加工物22の端末の位置を調整することにより、このようにして成形された糸はんだ4は、被加工物22に装着された状態となり、クランプ装置23から取り外した被加工物22は、これと接合する他の被加工物と嵌合した後、高周波コイルによりロー付けを可能とする。このようにすることにより、糸はんだ4を被加工物22に装着する作業が省略できる。
【0024】
また、この実施の形態においては被加工物22に糸はんだ4を巻回するようにしたが、被加工物22と同形の物材に糸はんだ4を巻回して、リング状の糸はんだを成形するようにしてもよい。
【0025】
【発明の効果】
以上のように本発明によると、糸はんだを被加工物の外周形状に倣ったリングを、その両端末がずれのない一致した突き合わせで成形することができ、両端末のずれを修正する工程が省略できる。

In the above-mentioned conventional manufacturing, since the spiral thread solder is cut, as shown in FIG. 7, the two terminals 5 after cutting have a different shape, and a ring in which both terminals coincide with each other cannot be obtained. The form in which the two terminals 5 are different from each other affects the fitting to the pipe, and also affects the uniformity of the brazing of the fitting portion between the large-diameter pipe 6 and the small-diameter pipe 7.
[0005]
Therefore, conventionally, correction processing has been performed so that both ends 5 coincide with each other in the molding die after the cutting. Therefore, the cost is high, and the modified ring-shaped thread solder 4a is manually fitted into the pipe, which causes a problem in work efficiency.

A bobbin 3 on which the wire solder 4 has been wound is rotatably supported on the vertical wall 11, and a feed device 12 for feeding the wire solder 4 unwound from the bobbin 3 in a predetermined direction is provided. The feed device 12 is a pair of rollers 12b rotated by a motor 12a.
[0009]
A support base 13 is fixedly mounted on a base 10 opposite to the position where the bobbin 3 is pivotally supported, and a pair of left and right pieces 15a and 15b is provided on the support base 13. The pair of left and right pieces 15a, 15b has a receiving surface 28 for the thread solder 4 on the upper surface, and bending dies 21a, 21b formed by concave grooves are formed on the opposing surfaces. At intervals of.
[0010]
The one piece 15a is provided with a guide 18 for the thread solder 4 sent by the feed device 12 and an entry gap 19 for a cutter 16 described later. The other piece 15b is provided with a stopper bolt 20 for regulating the end of the thread solder 4 sent by the feed device 12.
[0011]
A cutter 16 that is moved up and down by an actuator 17 is disposed above the one piece 15a. The cutter 16 cuts the thread solder 4 regulated by the stopper bolt 20 at a predetermined length.
[0012]
Further, a clamp device 23 is provided alongside the pieces 15a and 15b. The clamp device 23 clamps the workpiece 22 to which the thread solder 4 is mounted and moves up and down. As shown in FIG. 3, the structure includes a table 25 which moves up and down by a cylinder 24, and a clamper 27 which moves up and down with respect to the table 25 by a cylinder 26. 22 is held down by a clamper 27.
[0013]
The workpiece 22 on the table 25 is clamped in an axial direction orthogonal to the axis of the thread solder 4 sent onto the pieces 15a and 15b, and a clamping device 23 is provided on the opposite surface of the pieces 15a and 15b. The workpiece 22 is moved up and down from above the thread solder 4 on the blocks 15a and 15b so as to be positioned on the bending dies 21a and 21b.
[0014]
In the illustrated example, the workpiece 22 is a circular pipe, and the bending dies 21a and 21b provided on the opposing surfaces of the pieces 15a and 15b are formed by semicircular concave grooves corresponding to the outer shape of the pipe. , An ellipse, a triangle, a square, or any other external shape, and the bending dies 21a, 21b have shapes corresponding to the external shape of the workpiece.
[0015]
The operation of the present invention with the above configuration will be described. The thread solder 4 unwound from the bobbin 3 is sent in the direction of the pieces 15a, 15b by the rollers 12b of the feeder 12, and passes through the guide 18 of one piece 15a which is separated to the left and right, and the other piece 15b The ends of the thread solder 4 are restricted from coming into contact with the stopper bolts 20, and the thread solder 4 between the pieces 15a and 15b is supported by receiving surfaces 28 provided on the pieces 15a and 15b, respectively. At this time, the workpiece 22 clamped by the clamp device 23 is located above the thread solder 4 sent onto the pieces 15a and 15b.
[0016]
After the end of the thread solder 4 is restricted from coming into contact with the stopper bolt 20, the motor 12a of the feeding device 12 is stopped, and the cutter 16 is operated by the actuator 17 to be supported on the receiving surfaces 28 of the pieces 15a, 15b. The thread solder 4 is cut.
[0017]
This cutting length is a cutting length of the thread solder 4 controlled by the stopper bolt 20 from the end of the thread solder 4 by the cutter 16, and this length is substantially equal to the circumferential length of the workpiece 22.
[0018]
After the cutting of the thread solder 4, the clamp device 23 operates to descend. The workpiece 22 being clamped by the lowering operation of the clamp device 23 descends from above the cut thread solder 4 and removes the cut thread solder 4 on the pieces 15a and 15b as shown in FIG. It is hooked and positioned on the bending dies 21a and 21b.
[0019]
When the wire solder 4 is hooked and lowered by the workpiece 22, the thread solder 4 is preliminarily bent in a U-shape between the opposing surfaces G of the pieces 15a and 15b which are separated from each other. Therefore, it is desirable that the interval between the opposing surfaces G of the pieces 15a and 15b is set to a size equivalent to twice the diameter of the workpiece 22 and the diameter of the thread solder 4.
[0020]
After the thread solder 4 is hooked on the workpiece 22 and positioned on the bending dies 21a and 21b, the pieces 15a and 15b are actuated by the actuator 14 so that their opposing surfaces approach each other.
[0021]
When the opposing surfaces of the pieces 15a and 15b approach each other, the thread solder 4 which has been hooked on the workpiece 22 and has already been preliminarily bent in a U-shape around the outer periphery of the workpiece 22 is formed into a bending mold 21a. , 21b around the outer peripheral surface of the workpiece 22 around the outer peripheral surface.
[0022]
Both ends of the thread solder 4 wound around the outer peripheral surface of the workpiece 22 are formed by butting with the cut length and the bending dies 21a and 21b so as to be consistent with each other without displacement.
[0023]
For example, by adjusting the position of the terminal of the workpiece 22 so that the position of the terminal of the workpiece 22 and the position of winding the thread solder 4 match, the thread solder 4 thus formed can The workpiece 22 detached from the clamp device 23 in a state of being mounted on the workpiece 22 can be brazed by a high-frequency coil after being fitted with another workpiece to be joined thereto. By doing so, the operation of attaching the thread solder 4 to the workpiece 22 can be omitted.
[0024]
In this embodiment, the thread solder 4 is wound around the workpiece 22. However, the thread solder 4 is wound around a material having the same shape as the workpiece 22 to form a ring-shaped thread solder. You may make it.
[0025]
【The invention's effect】
