Description

本発明は、機械的接合による異種金属接合方法に関する。 The present invention relates to a method for joining dissimilar metals by mechanical joining.

従来から、機械的接合により、異種金属同士を接合する方法としては、特許文献1に示す方法が知られている。この異種金属接合体は、電池の端子部品として用いられるもので、アルミニウム材で成る板状体に凹部を設け、この凹部に銅材で成る軸部を圧入することにより両部材が接合されている。 Conventionally, as a method of joining dissimilar metals by mechanical joining, the method shown in Patent Document 1 is known. This dissimilar metal joint is used as a terminal component of a battery, and both members are joined by providing a recess in a plate-shaped body made of an aluminum material and press-fitting a shaft portion made of a copper material into the recess. ..

しかしながら、上記接合方法による異種金属接合体は、圧入により接合されているので、圧入される側の部品(板状体)には圧入代として、所定の厚みが必要になるため、厚みに制限があった。 However, since the dissimilar metal joints obtained by the above joining method are joined by press fitting, the thickness of the part (plate-shaped body) to be press-fitted is limited because a predetermined thickness is required as a press-fitting allowance. there were.

本発明は、上記問題に鑑みて創成されたものであり、厚みの薄い第1金属部と第2金属部材とを機械的接合により接合可能な異種金属接合方法を提供することを目的とする。 The present invention has been created in view of the above problems, and an object of the present invention is to provide a dissimilar metal joining method capable of joining a thin first metal portion and a second metal member by mechanical joining.

上記課題は、第1金属部材と第2金属部材とを接合する異種金属部材の接合方法において、第1金属部材は、頭付き部品であって、平板状の頭部と、この頭部に一体成形される軸部とから成り、第2金属部材は、棒状部品であって、第1金属部材の凹部に嵌合可能な凸部を一端に有し、これら第1金属部材および第2金属部材を、第1金属部材の頭部が露出するように受け型で保持し、第1金属部材の頭部を上方から圧縮することにより、頭部を扁平させるとともに、第1金属部材の凹部と第2金属部材の凸部とが圧着することにより両部材を接合する異種金属接合方法によって解決できる。 The above problem is in a method of joining dissimilar metal members for joining a first metal member and a second metal member. The first metal member is a headed part, and is integrated with a flat head and the head. The second metal member is a rod-shaped part, which is composed of a shaft portion to be molded, and has a convex portion that can be fitted into a concave portion of the first metal member at one end, and these first metal member and second metal member. Is held in a receiving mold so that the head of the first metal member is exposed, and the head of the first metal member is compressed from above to flatten the head, and the recess and the first of the first metal member. 2 It can be solved by a dissimilar metal joining method in which both members are joined by crimping with the convex portion of the metal member.

なお、第2金属部材の凸部は、圧縮に伴ってその端面が外方に扁平することによりアンダーカット部が成形されることが好ましい。 It is preferable that the convex portion of the second metal member is formed with an undercut portion by flattening its end face outward with compression.

本発明によれば、第1金属部材の厚みが薄いため、第1金属部材および第2金属部材の接合において接合部に圧入代をとれない構造であっても、両部材を機械的接合により強固に接合することができる。 According to the present invention, since the thickness of the first metal member is thin, even if the structure is such that a press-fitting allowance cannot be taken in the joint portion when joining the first metal member and the second metal member, both members are strengthened by mechanical joining. Can be joined to.

以下、本発明である異種金属部材の接合方法を実施するための形態を図面に基づいて説明する。図1において、10はアルミニウム材料でなる第1金属部材、20は銅でなる第2金属部材である。これら第1金属部材10および第2金属部材20は、予め別個に成形され準備されるものである。 Hereinafter, a mode for carrying out the method for joining dissimilar metal members according to the present invention will be described with reference to the drawings. In FIG. 1, 10 is a first metal member made of an aluminum material, and 20 is a second metal member made of copper. The first metal member 10 and the second metal member 20 are separately molded and prepared in advance.

第1金属部材10は、頭付き部品であり、平板状の頭部11と、この頭部11に一体成形される軸部12とから成る。また、第1金属部材10の軸部12の端部には、凹部13が設けられている。 The first metal member 10 is a headed part, and includes a flat plate-shaped head portion 11 and a shaft portion 12 integrally formed with the head portion 11. Further, a recess 13 is provided at the end of the shaft portion 12 of the first metal member 10.

第2金属部材20は、棒状部品であって、第1金属部材10の凹部13に嵌合可能な凸部21を一端に有する。 The second metal member 20 is a rod-shaped part and has a convex portion 21 at one end that can be fitted into the concave portion 13 of the first metal member 10.

第1金属部材10の凹部13の内径および第2金属部材20の凸部21の外径は嵌合可能な程度に同一寸法に設定されている。 The inner diameter of the concave portion 13 of the first metal member 10 and the outer diameter of the convex portion 21 of the second metal member 20 are set to the same dimensions so that they can be fitted.

これら第1金属部材10および第2金属部材20を接合する方法として、まずは、第1工程として、図1に示すように、両部材10,20の凹凸13,21を嵌合させた状態のものを受け型1で保持する。受け型1は、第1金属部材10の軸部12および第2金属部材20が挿通可能な挿入孔2を有しており、第1金属部材10の頭部11の座面14を受け型の上面に着座させ、当該第1金属部材10の頭部11を露出させて保持するように構成されている。このとき、受け型1の挿入孔2の内部には、ノックアウトピン3が配置されており、第2金属部材20の他端を下方から支持するように構成されている。 As a method of joining the first metal member 10 and the second metal member 20, first, as a first step, as shown in FIG. 1, a state in which the irregularities 13 and 21 of both members 10 and 20 are fitted. Hold in the receiving mold 1. The receiving mold 1 has an insertion hole 2 through which the shaft portion 12 of the first metal member 10 and the second metal member 20 can be inserted, and the receiving mold 1 has a seating surface 14 of the head portion 11 of the first metal member 10. It is configured to be seated on the upper surface and to expose and hold the head 11 of the first metal member 10. At this time, a knockout pin 3 is arranged inside the insertion hole 2 of the receiving mold 1, and is configured to support the other end of the second metal member 20 from below.

続いて、第2工程として、図2に示すように、プレス金型4で第1金属部材10の頭部11を上方から圧縮する。これにより、第1金属部材10の頭部11は、外方へ扁平し、厚みが薄くなる。これに伴い、第1金属部材10の凹部13と第2金属部材20の凸部21とが圧着することにより両部材10,20が接合される。 Subsequently, as a second step, as shown in FIG. 2, the head portion 11 of the first metal member 10 is compressed from above by the press die 4. As a result, the head portion 11 of the first metal member 10 is flattened outward and thinned. Along with this, both members 10 and 20 are joined by crimping the concave portion 13 of the first metal member 10 and the convex portion 21 of the second metal member 20.

さらに、圧縮を継続することにより、第2金属部材20の凸部21は、その端面が外方に扁平するに塑性変形することによりアンダーカット部22が成形される。アンダーカット部22の成形に伴い、第1金属部材10の凹部13は塑性変形し、アンダーカット部22の背面へ流動する。これにより、第1金属部材10と、第2金属部材20とを軸方向に係合させて強固な抜け止め効果を発揮する。 Further, by continuing the compression, the convex portion 21 of the second metal member 20 is plastically deformed so that its end face is flattened outward, so that the undercut portion 22 is formed. Along with the molding of the undercut portion 22, the recess 13 of the first metal member 10 is plastically deformed and flows to the back surface of the undercut portion 22. As a result, the first metal member 10 and the second metal member 20 are engaged in the axial direction to exert a strong retaining effect.

最後に、第3工程として、図3に示すように、ノックアウトピン3を上方へ前進させることにより、第1金属部材10と第2金属部材20の接合体が受け型1から排出される。 Finally, as a third step, as shown in FIG. 3, by advancing the knockout pin 3 upward, the joint body of the first metal member 10 and the second metal member 20 is discharged from the receiving mold 1.

なお、排出された接合体については、第1金属部材10の頭部11の外周を打ち抜き加工することにより、所望の寸法にすることも可能である。その他にも、本発明は上記の実施形態に限定されることなく、本発明の趣旨を逸脱しない範囲で種々の変形が可能である。 The discharged joint can be made into a desired size by punching the outer periphery of the head 11 of the first metal member 10. In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
