There is. However, such conventional devices have a large number of cams for mounting punches, so the structure of the cam driver for driving the cams becomes complicated, resulting in problems such as a decrease in the strength of the cam driver and an increase in cost. There is. Furthermore, when attaching the punch to the cam, there is a problem in that it takes time and effort to position the punch. Furthermore, there is a problem in that it takes time and effort to remove the shell from the die after processing is completed. The present invention solves the above-mentioned conventional problems, and it uses four cam drivers to drive a large number of cams, and only one cam driver needs to be provided with a cam guide groove. The main feature is that it has been designed as follows, which is explained using the drawings. In FIG. 1, which is a vertical cross-sectional view, the shell 1 is supported in substantially close contact with the upper surface of an annular die 3 with the annular concave surface 2 facing upward.

い。By the way, in the conventional product, as shown in Fig. 5 (first cam driver 4
In addition to 1a, the second, third, and fourth cam drivers 42a
, 43a, 44a (second and fourth cam drivers 42a,
44a is integral) Vc is also cam guide groove 49b, 49c, 49
d, so the cam drivers 42a, 43a, 4
The strength of 4a is reduced, and the processing becomes complicated, causing an increase in cost. Furthermore, in the conventional product, it is necessary to accurately set the position of the third cam driver 43a in the circumferential direction in order to align the groove 49c with the other grooves 49a, 49b, and 49d.
A are connected by a vertical guide pin 80, but the attachment of the pin 80 also complicates processing and assembly, leading to an increase in cost. In contrast, in the present invention shown in FIG. 1, the third cam driver 43 has a tapered lower surface 59.
Since the cam 36 is guided by the third cam driver 43, there is no limit to the position of the third cam driver 43 in the circumferential direction, and there is no need to provide a positioning pin between the third cam driver 43 and the punch holder 25.

The fact that 4 is a separate product also contributes to the simplification of processing and cost reduction. As shown in Figure 2〈Punch 3
1 has a rectangular cross section, the punch 31 can be easily positioned with respect to the cam 36 shown in FIG.
