た。 In other words, according to the conventional method, when the clad wire 1 is cut with the cutting punch 3 as shown in FIG. 4, the cut surfaces become sloping 1a and burrs 1b, and the thickness dimensions of the contact layers are different, and when looking at each cross section, one side is the base material. 1″
The contact layer 1' bites into the contact layer 1', and the other contact layer 1' bites into the base material 1''. When the thus cut piece is used as a contact as shown in Fig. 5, the base material becomes a contact. It digs into the layer, shortening the product life and causing contact welding accidents. Therefore, in the process leading up to the present invention, a cut was made in advance in the clad wire 1 with a punch whose cutting edge was formed at an acute angle, and then the cutting process was performed. However, as shown in Fig. 6a and b, if the feed rate of the clad wire 1 is small or large, burrs 1c that cause chips will be generated at the cut section, resulting in failure. There was a problem that it caused non-defective products and mold breakage accidents.
本発明の目的は複合材を切断して接点を形成す

The present invention provides a composite material cutting method for cutting a composite material made by laminating dissimilar metals, in which a flat part is cut at the bottom at a depth approximately equal to the thickness of the surface member at the cutting position before the composite material cutting step. The method is characterized in that a notch is formed by performing a notch process, and then the notch is cut. Further, the present invention includes a first punch provided to form a notch in the upper surface member of the composite material, and a second punch provided to cut the composite material at the notch. In the composite material cutting mold, the first punch has a wedge-shaped cutting edge with a flat portion at the tip thereof.
