Abstract
PURPOSE: To prevent the bending deformation of a punch and make possible long- hole working by guiding the punch to a die by way of a bushing.
CONSTITUTION: A stock material 16 is supplied into a die 10. When a male die descends, a piston 19 abuts on a stripper plate 5, and a bushing 4 is lowered by way of a stripper plate 5, by which the lower outside circumferential part of the bushing 4 is fitted into the hole of the die 10. When the male die descends further, the punch 1 backward extrudes the blank material and blanks the same. The blanked scrap is removed through a ring die 8, a die plate 15, a chute 11 and the hole in the upper part of the means of knock-out. Next, when the male die ascends, the punch 1 goes out from the product 17, and the stripper plate 5 etc. are moved upward by the effect of a spring 14, and the product 17 is pushed upward by a knock-out 12 by way of the ring die 8 and the pin 7, and is taken out from the die 10.
