落下していた。(Prior Art) Conventionally, in order to make a rivet-type electric contact, a base material 1 and a contact material 2 shown in FIG. 2a, a leg die 4 having a knockout pin 3 as shown in FIG. Forming punch 5
Rivet type electrical contact 6 which is pressed by the head and is granular as a head group
Then, the head portion 6a of the rivet-type electrical contact 6 is finished into a trapezoidal head 8 by a finishing forming punch 7 having a circular trapezoidal recess 7a as shown in FIG. 2c. It was molded to obtain a rivet-type electrical contact 9. Then, the rivet type electrical contact 9 was knocked out by the knockout pin 3 as shown in FIG. 3D and discharged and dropped from the hole 4a of the leg die 4.
（発明が解決しようとする問題点） ところで、上記リベット型電気接点９の脚部10を成形

えりが発生するという問題点があった。(Problems to be Solved by the Invention) By the way, the hole 4a of the leg die 4 for molding the leg 10 of the rivet-type electrical contact 9 is generally a straight hole 4a as shown in FIG. As shown in FIG. 3, it is divided into two holes 4b. The straight hole 4a shown in FIG. 2d has the advantage that the length of the leg portion 10 of the rivet-type electrical contact 9 can be freely changed. Since the contact area of the leg portion 10 is large, the load at the time of knocking out the rivet-type electrical contact 9 is large, and there is a problem that the knockout pin 3 is broken or the bottom surface of the leg portion 10 is burred or burred.

Pre-formed into a rivet-type electrical contact with a head group granule,
Then, in the processing method of the rivet-type electrical contact in which the aggregated head of the rivet-type electrical contact is finish-molded with a finish-forming punch, in the leg die, the opening diameter of the hole is It is characterized by using a leg die having a tapered hole larger than the diameter.

Since the friction resistance between the tapered hole and the leg is small and the load is small, you can easily knock out the rivet type electrical contact from the leg die, break the knockout pin, or flash on the bottom of the leg of the rivet type electrical contact. It does not cause burr.
