Abstract
PURPOSE: A simple blanking die which is obtained by simultaneously blanking two or more sheets of metal plates laminated on a base die by a punch and which is easy to manufacture and permits precision shearing without requiring any skill.
CONSTITUTION: A base die 4 has a punch 1 and a large clearance of about 0.6mm, and does not require high accuracy of contour sizes and does not require any heat treatment either. A hard metal plate 2 and an auxiliary laminated plate 3 of the same quality as this or softer than this which are fixed to each other by means of screws or the like are placed on this. When the die 2 and the plate 3 are simultaneously blanked by the punch 1 and the base die 4, the blanking force from the punch 1 and the reaction force from the plate 3 act upon the die 2, causing the die 2 to be compressed in the plate thickness direction. As a result, the occurrence of cracking near the punch biting part of the die is suppressed. On the other hand, the resistance against the deformation at the blanking becomes high because the plates 2, 3 are superposed and blanked. Accordingly, a blanked face of small deformation, good sectional characteristic and of the same contour size as that of the punch 1 is formed in the die 2 and this is used as a die cutting blade.
