Abstract

PURPOSE: To prevent generation of burrs or whiskerlike projections on the back of a plate by installing a mechanism that pushes up momentarily the blanked part of a plate blanked by an upper die punch with a lower die punch.
CONSTITUTION: A plate A is inserted into a lower die plate 14. An upper die is lowered and the plate A is blanked by an upper die punch 10, and a part of blanked part A1 is pushed out in the lower die plate 14. When the upper die goes down further, the lower die plate 14 is pushed down by an upper die plate 9 and goes down. At the same time, the tip of a lower punch 15 that penetrates to the lower die plate 14 starts to project to the upper face of the lower die plate, and the blanked part A1 of the plate A pushed to the lower die plate 14 is pushed upwards. When the upper die starts ascending by further operation of the press machine, the descending lower die plate 14 starts ascending while following the upper die plate 9, and the blanked part A1 is pressed into the body of the plate A.
