以下、図面を参照して本発明の実施形態について説明する。図１は、本発明の一実施形態に係るリード線成形装置の概略的な構成を示す斜視図である。本実施形態に係るリード線成形装置１は、コイルＣの一端から延出されたリード線Ｌを成形するものである。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a schematic configuration of a lead wire forming apparatus according to an embodiment of the present invention. The lead wire forming apparatus 1 according to the present embodiment forms a lead wire L extending from one end of a coil C.

コイルＣは、例えば、電動機用ステータに用いられるものであり、ロータと共に、電気自動車やハイブリッド自動車の走行駆動源あるいは発電機として用いられる３相交流電動機を構成するものである。コイルＣは、例えば、矩形断面を有する平角材を複数回にわたって巻回することにより形成され、その一端からは長尺のリード線Ｌが延出される。本実施形態に係るリード線成形装置１は、コイルＣから延出されたこのリード線Ｌを所定形状に成形するものである。   The coil C is used, for example, for a stator for an electric motor, and constitutes a three-phase AC motor used as a driving source or a generator for an electric vehicle or a hybrid vehicle together with a rotor. The coil C is formed, for example, by winding a rectangular material having a rectangular cross section a plurality of times, and a long lead wire L is extended from one end thereof. The lead wire forming apparatus 1 according to the present embodiment forms the lead wire L extended from the coil C into a predetermined shape.

リード線成形装置１は、例えば、図１に示す如く、リード線Ｌをエッジワイズ方向（断面の短辺と略直交する方向、ＥＷ方向）及びフラットワイズ方向（断面の長辺と略直交する方向、ＦＷ方向）に複数回曲げることで、リード線Ｌを成形する。これは、リード線Ｌ同士の干渉を抑えつつコイルＣをコンパクト化するため行われる。コイルＣは、例えば、熱硬化性樹脂あるいは熱可塑性樹脂などのモールド樹脂により被覆されている。   For example, as shown in FIG. 1, the lead wire forming apparatus 1 moves the lead wire L in an edgewise direction (a direction substantially orthogonal to the short side of the cross section, the EW direction) and a flatwise direction (a direction substantially orthogonal to the long side of the cross section). , The lead wire L is formed by bending a plurality of times in the FW direction. This is performed to make the coil C compact while suppressing interference between the lead wires L. The coil C is covered with a mold resin such as a thermosetting resin or a thermoplastic resin.

本実施形態に係るリード線成形装置１は、リード線Ｌの始端部を固定する第１成形型１１と、第１成形型１１に隣接し、該第１成形型１１に対して第１方向へ相対移動する第２成形型１２と、第１成形型１１に隣接し、第１成形型１１に対して第１方向に相対移動する第３成形型１３と、を備えている。   The lead wire forming apparatus 1 according to the present embodiment is adjacent to the first forming die 11 for fixing the leading end portion of the lead wire L and the first forming die 11, and in the first direction with respect to the first forming die 11. A second molding die 12 that moves relative to the first molding die 11 and a third molding die 13 that moves relative to the first molding die 11 in the first direction are provided.

第１成形型１１は、リード線成形装置１の設置箇所に対して固定される固定型である。第１成形型１１は、コイルＣのリード線Ｌの中間部Ｌ１をエッジワイズ方向及びフラットワイズ方向に複数回曲げて、所定形状を成形するための成形面を有している。   The first mold 11 is a fixed mold that is fixed to the installation location of the lead wire forming apparatus 1. The first forming die 11 has a forming surface for forming a predetermined shape by bending the intermediate portion L1 of the lead wire L of the coil C a plurality of times in the edgewise direction and the flatwise direction.

図１に示す如く、第１成形型１１は、コイルＣのリード線Ｌの中間部Ｌ１をエッジワイズ方向に成形するためのエッジワイズ成形面（不図示）と、リード線Ｌの中間部Ｌ１をフラットワイズ方向に成形するためのフラットワイズ成形面１４とを有している。エッジワイズ成形面は、フラットワイズ成形面１４に沿って延在し、リード線Ｌの中間部Ｌ１をエッジワイズ方向に所定形状に曲げるように曲面が形成されている。   As shown in FIG. 1, the first mold 11 includes an edgewise molding surface (not shown) for molding the intermediate portion L1 of the lead wire L of the coil C in the edgewise direction, and an intermediate portion L1 of the lead wire L. And a flatwise molding surface 14 for molding in the flatwise direction. The edgewise molding surface extends along the flatwise molding surface 14, and a curved surface is formed so that the intermediate portion L1 of the lead wire L is bent into a predetermined shape in the edgewise direction.

フラットワイズ成形面１４は、リード線Ｌの中間部Ｌ１をフラットワイズ方向に所定形状に曲げるように曲面が形成されている。フラットワイズ成形面１４には、例えば、後述する、第２成形型１２によるリード線Ｌの中間部Ｌ１の引き摺られを防止するための突起部１５が形成されていてもよい。第２成形型１２が第１成形型１１から離脱する際に、リード線Ｌの中間部Ｌ１が第２成形型１２に引き摺られ、変位しようとする。しかし、リード線Ｌの中間部Ｌ１がこの突起部１５に引っ掛るため、中間部Ｌ１が第２成形型１２に引き摺られ、第２成形型１２の離間方向へ変位するのを抑制できる。   The flatwise molding surface 14 is formed with a curved surface so that the intermediate portion L1 of the lead wire L is bent into a predetermined shape in the flatwise direction. On the flatwise molding surface 14, for example, a protrusion 15 for preventing the intermediate portion L1 of the lead wire L from being dragged by the second molding die 12, which will be described later, may be formed. When the second mold 12 is detached from the first mold 11, the intermediate portion L1 of the lead wire L is dragged by the second mold 12 and tends to be displaced. However, since the intermediate portion L1 of the lead wire L is hooked on the protruding portion 15, it is possible to suppress the intermediate portion L1 from being dragged by the second molding die 12 and being displaced in the separating direction of the second molding die 12.

第２成形型１２は、電動モータあるいは流体圧シリンダ等を含む駆動ユニット１６により駆動される移動型である。第２成形型１２は、第１成形型１１に対して第１方向へ相対移動して、第１成形型１１との間でリード線Ｌを挟み込むことでリード線Ｌの中間部Ｌ１を成形する。   The second mold 12 is a movable mold that is driven by a drive unit 16 including an electric motor or a fluid pressure cylinder. The second mold 12 is moved relative to the first mold 11 in the first direction, and the lead wire L is sandwiched between the second mold 12 and the intermediate portion L1 of the lead wire L. .

第２成形型１２は、図１に示す如く、第１方向に相対移動して固定型である第１成形型１１に接近すると共に、第１方向に移動して第１成形型１１から離間することができる。   As shown in FIG. 1, the second mold 12 moves relative to the first direction to approach the first mold 11 that is a fixed mold, and moves in the first direction to move away from the first mold 11. be able to.

第２成形型１２は、第１成形型１１のエッジワイズ成形面に対応した、コイルＣのリード線Ｌの中間部Ｌ１をエッジワイズ方向に成形するためのエッジワイズ成形面（不図示）と、第１成形型１１のフラットワイズ成形面１４に対応した、リード線Ｌの中間部Ｌ１をフラットワイズ方向に成形するためのフラットワイズ成形面（不図示）と、を有している。第２成形型１２のエッジワイズ成形面は、第１成形型１１のエッジワイズ成形面と平行に延在するように形成されている。   The second molding die 12 corresponds to the edgewise molding surface of the first molding die 11, an edgewise molding surface (not shown) for molding the intermediate portion L1 of the lead wire L of the coil C in the edgewise direction, It has a flatwise molding surface (not shown) corresponding to the flatwise molding surface 14 of the first mold 11 for molding the intermediate portion L1 of the lead wire L in the flatwise direction. The edgewise molding surface of the second molding die 12 is formed so as to extend in parallel with the edgewise molding surface of the first molding die 11.

第２成形型１２が第１成形型１１に接近することで、第２成形型１２のエッジワイズ成形面は、第１成形型１１のエッジワイズ成形面とでリード線Ｌの中間部Ｌ１を挟み込み加圧することで、その中間部Ｌ１を第１成形型１１のエッジワイズ成形面の曲面に沿った所定形状に成形する。同時に、第２成形型１２のフラットワイズ成形面は、第１成形型１１のフラットワイズ成形面１４とでリード線Ｌの中間部Ｌ１を挟み込み加圧することで、その中間部Ｌ１を第１成形型１１のフラットワイズ成形面の曲面に沿った所定形状に成形する。   When the second molding die 12 approaches the first molding die 11, the edgewise molding surface of the second molding die 12 sandwiches the intermediate portion L1 of the lead wire L with the edgewise molding surface of the first molding die 11. By pressurizing, the intermediate portion L1 is molded into a predetermined shape along the curved surface of the edgewise molding surface of the first molding die 11. At the same time, the flat part molding surface of the second mold 12 is sandwiched and pressed between the flat part molding surface 14 of the first mold 11 and the intermediate part L1 of the lead wire L, so that the intermediate part L1 becomes the first mold. 11 is molded into a predetermined shape along the curved surface of the flatwise molding surface.

第３成形型１３は、第２成形型１２と同様に、駆動ユニット１６により駆動される移動型である。第３成形型１３は、固定型である第１成形型１１に対して上記第２成形型１２の移動方向と平行に第１方向に移動可能な移動型である。第３成形型１３は、第１成形型１１に対して第１方向に相対移動することで、リード線Ｌの先端部Ｌ２を押圧し、先端部Ｌ２を第１方向（エッジワイズ方向）へ変形させる。   Similar to the second mold 12, the third mold 13 is a movable mold that is driven by the drive unit 16. The third mold 13 is a movable mold that can move in the first direction parallel to the movement direction of the second mold 12 with respect to the first mold 11 that is a fixed mold. The third mold 13 moves relative to the first mold 11 in the first direction, thereby pressing the tip L2 of the lead wire L and deforming the tip L2 in the first direction (edgewise direction). Let

第３成形型１３は、図１に示す如く、第１方向に相対移動して固定型である第１成形型１１に接近すると共に、第１方向に移動して第１成形型１１から離間することができる。第３成形型１３は、第２成形型１２と協働してリード線Ｌの先端部Ｌ２をエッジワイズ方向に成形可能なものである。第３成形型１３は、リード線Ｌの先端部Ｌ２にエッジワイズ方向に成形するための曲面を含むエッジワイズ成形面を有する。図２は、第１乃至第３成形型でリード線を挟み込んだ状態を示す断面図である。図３は、図２に示すＡ部分を拡大した拡大図である。   As shown in FIG. 1, the third mold 13 moves relatively in the first direction to approach the first mold 11 that is a fixed mold, and moves in the first direction to move away from the first mold 11. be able to. The third mold 13 is capable of forming the leading end L2 of the lead wire L in the edgewise direction in cooperation with the second mold 12. The 3rd shaping | molding die 13 has an edgewise shaping | molding surface containing the curved surface for shape | molding in the edgewise direction at the front-end | tip part L2 of the lead wire L. As shown in FIG. FIG. 2 is a cross-sectional view showing a state in which the lead wire is sandwiched between the first to third molds. FIG. 3 is an enlarged view of an A portion shown in FIG.

ところで、第２及び第３成形型１２、１３が第１成形型１１に接近し、リード線Ｌの中間部Ｌ１及び先端部Ｌ２が所定形状に成形されると、続いて、第３成形型１３が第１成形型１１から離間し、離脱する。このとき、第１成形型１１及び第３成形型１３でリード線Ｌの先端部Ｌ２をエッジワイズ方向に成形した際に先端部Ｌ２の断面の厚さがフラットワイズ方向に増加している。このため、第３成形型１３とリード線Ｌの先端部Ｌ２との摩擦力が増加し、この摩擦力により、先端部Ｌ２は第３成形型１３に引き摺られ変位しようとする。しかし、第１及び第２成形型１１、１２によりリード線Ｌの中間部Ｌ１が固定されているため、先端部Ｌ２は第３成形型１３に引き摺られず、変位しない。   By the way, when the second and third molds 12 and 13 approach the first mold 11 and the intermediate portion L1 and the tip portion L2 of the lead wire L are molded into a predetermined shape, then, the third mold 13 Is separated from the first mold 11 and detached. At this time, when the tip portion L2 of the lead wire L is molded in the edgewise direction with the first molding die 11 and the third molding die 13, the thickness of the cross section of the tip portion L2 increases in the flatwise direction. For this reason, the frictional force between the third mold 13 and the tip L2 of the lead wire L increases, and the tip L2 is dragged by the third mold 13 and tends to be displaced by this frictional force. However, since the intermediate portion L1 of the lead wire L is fixed by the first and second molds 11 and 12, the leading end L2 is not dragged by the third mold 13 and is not displaced.

一方、第２成形型が第１成形型から離間し、離脱する際、第３成形型と同様に、リード線Ｌの中間部は、十分に固定さていないため、第２成形型に引き摺られ変位しようとする。上述のフラットワイズ成形面に突起部が形成されている場合でも、リード線Ｌの中間部がこの突起部に引っ掛るが、リード線の先端部と離れた位置に突起部が設けられているため、第２成形型の引き摺りを抑えきれず、中間部の先端部側が引き摺られ第２成形型の離間方向へ変形する。   On the other hand, when the second mold is separated from and separated from the first mold, the intermediate portion of the lead wire L is not sufficiently fixed as in the case of the third mold, so that the second mold is dragged and displaced by the second mold. try to. Even when a protrusion is formed on the flatwise molding surface described above, the intermediate portion of the lead wire L is caught by this protrusion, but the protrusion is provided at a position away from the tip of the lead wire. The drag of the second mold cannot be suppressed, and the tip end side of the intermediate part is dragged and deformed in the separating direction of the second mold.

これに対し、本実施形態においては、第１成形型１１と第２成形型１２との間でリード線Ｌを挟み込んだ状態で、第２成形型１２とリード線Ｌとの間に所定の隙間Ｄが形成されるように、第１及び第２成形型１２が構成されている。この第２成形型１２とリード線Ｌとの間に所定の隙間Ｄによって、リード線Ｌは第２成形型１２により引き摺られず、第２成形型１２の離間方向へ変形することがない。   On the other hand, in the present embodiment, a predetermined gap is provided between the second mold 12 and the lead wire L in a state where the lead wire L is sandwiched between the first mold 11 and the second mold 12. The first and second molding dies 12 are configured so that D is formed. Due to the predetermined gap D between the second mold 12 and the lead wire L, the lead wire L is not dragged by the second mold 12 and is not deformed in the separating direction of the second mold 12.

図４は、リード線Ｌの中間部Ｌ１が第１及び第２成形型１２により挟み込まれた状態における中間部Ｌ１の断面図である。図４に示す如く、第２成形型１２とリード線Ｌとの間に所定の隙間Ｄが形成されている。この所定の隙間Ｄは、上述の如く、第１成形型１１及び第３成形型１３でリード線Ｌの先端部Ｌ２をエッジワイズ方向に成形した際にリード線Ｌの中間部Ｌ１の断面の厚さがフラットワイズ方向に増加するのを考慮して、例えば、０．２ｍｍ以上（リード線Ｌの被膜厚さ程度）に形成されている。上記の所定の隙間Ｄが形成されるように、例えば、第１及び第２成形型１２の間隔、形状などが設定される。   FIG. 4 is a cross-sectional view of the intermediate portion L1 in a state where the intermediate portion L1 of the lead wire L is sandwiched between the first and second molding dies 12. As shown in FIG. 4, a predetermined gap D is formed between the second mold 12 and the lead wire L. As described above, the predetermined gap D is the thickness of the cross section of the intermediate portion L1 of the lead wire L when the tip portion L2 of the lead wire L is formed in the edgewise direction by the first molding die 11 and the third molding die 13. For example, the thickness is formed to be 0.2 mm or more (about the film thickness of the lead wire L). For example, the interval and shape of the first and second molds 12 are set so that the predetermined gap D is formed.

次に、図５（ａ）乃至（ｄ）を用いて、リード線成形方法について説明する。
図５（ａ）に示す如く、まず、駆動ユニット１６は、第２成形型１２を第１方向に相対移動させて第１成形型１１に接近させる。これにより、第２成形型１２は、第１成形型１１とでリード線Ｌの中間部Ｌ１を挟み込み加圧する。この状態では、上記第２成形型１２とリード線Ｌとの間に所定の隙間Ｄが形成されていることから、リード線Ｌの中間部Ｌ１は、フラットワイズ方向にはゆるく曲げられた状態となっている。 Next, the lead wire forming method will be described with reference to FIGS.
As shown in FIG. 5A, first, the drive unit 16 relatively moves the second mold 12 in the first direction so as to approach the first mold 11. Thereby, the second mold 12 sandwiches and pressurizes the intermediate portion L1 of the lead wire L with the first mold 11. In this state, since the predetermined gap D is formed between the second mold 12 and the lead wire L, the intermediate portion L1 of the lead wire L is loosely bent in the flatwise direction. It has become.

続いて、図５（ｂ）に示す如く、駆動ユニット１６は、第３成形型１３を第１方向に相対移動させて第１成形型１１に接近させる。これにより、第３成形型１３は、第１成形型１１と協働して、リード線Ｌの先端部Ｌ２を押圧し、先端部Ｌ２を第１方向へ変形させる。この状態では、リード線Ｌの先端部Ｌ２はフラットワイズ方向に矯正されながら、エッジワイズ方向（第１方向）に曲げられた状態である。   Subsequently, as shown in FIG. 5B, the drive unit 16 moves the third molding die 13 in the first direction to approach the first molding die 11. Thereby, the 3rd shaping | molding die 13 cooperates with the 1st shaping | molding die 11, presses the front-end | tip part L2 of the lead wire L, and deform | transforms the front-end | tip part L2 to a 1st direction. In this state, the leading end L2 of the lead wire L is bent in the edgewise direction (first direction) while being corrected in the flatwise direction.

さらに、図５（ｃ）に示す如く、駆動ユニット１６は、第３成形型１３を第１成形型１１から離間し、離脱させる。このとき、リード線Ｌの先端部Ｌ２は第３成形型１３に引き摺られ変位しようとする。しかし、第１及び第２成形型１２によりリード線Ｌの中間部Ｌ１が固定されているため、先端部Ｌ２は第３成形型１３に引き摺られず、変位しない。   Furthermore, as shown in FIG. 5C, the drive unit 16 separates the third mold 13 from the first mold 11 and separates it. At this time, the leading end L2 of the lead wire L is dragged by the third mold 13 and tends to be displaced. However, since the intermediate portion L1 of the lead wire L is fixed by the first and second molding dies 12, the tip end portion L2 is not dragged by the third molding die 13 and is not displaced.

最後に、図５（ｄ）に示す如く、駆動ユニット１６は、、第２成形型１２を第１成形型１１から離間し、離脱させる。このとき、この第２成形型１２とリード線Ｌとの間に所定の隙間Ｄが形成されてるため、リード線Ｌは第２成形型１２により引き摺られず、第２成形型１２の離間方向へ変形することがない。   Finally, as shown in FIG. 5D, the drive unit 16 separates the second mold 12 from the first mold 11 and separates it. At this time, since a predetermined gap D is formed between the second mold 12 and the lead wire L, the lead wire L is not dragged by the second mold 12 and is deformed in the separating direction of the second mold 12. There is nothing to do.

なお、本発明は上記実施の形態に限られたものではなく、趣旨を逸脱しない範囲で適宜変更することが可能である。   Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
