Abstract
PURPOSE: To perform simultaneously two processes, hole-punching and press-fitting, by employing a punched hole of a raw material as a die, and punching out a different kind of material which is press-fit into a punched hole simultaneously.
CONSTITUTION: A main raw material plate 6 of hoop shape intermittently fed in a direction of an arrow (a) is successively punched hole by a metallic mold 1 and a hole-punch 2 in each intermittent feeding. Meanwhile, a blanking punch 3 is made confronting with a product hole 6a on said plate 7 at a stopped position in each intermittent feeding, performing a punching operation simultaneously with said hole punching operation, wherein a bottom dead center of the punch 3 is arranged coming just on the plate 6. Namely, in each descending of punches 2, 3, the product hole 6a is punched out by the punch 2, discharging a waste from a die 5 of the metallic mold 1. At the same time, the punch 3 punches an auxiliary plate 7 by the hole 6a used as a die in this position, press-fitting a blanked piece 7a into the hole 6a, and then ascends together with the punch 2 from its dead center of a press- fitted state.
