Abstract

The flat blank is placed on a die ring supported by pins in the press table over a cylindrical former, this having a chamfer. The press slide descends and a draw ring makes the first draw. This is placed on a die ring having a similar chamfer (10) and a bottom flange (12) supported on the table pins (13). The former (16) has a shaped nose (17) and the draw ring (19) on the slide (20, 21) a chamfered entry (22). This second draw form is finally placed over a cylindrical former of identical shape and the sides drawn to the final dimension by a double angle draw ring.
