DIE OF NUMERICALLY CONTROLLED PRESS DEVICE

摘要

PURPOSE:To prevent the generation of the surface roughness on the abutting surface with the material to be worked on the die of die, etc., or the cut flaw and scratch generated with the build-up edge top generated at the cutting edge of die blade by making the material to be worked in contact with the die cutting edge face with the stripper member at the working time of the material to be worked. CONSTITUTION:A spherical rotary body 10 and an elastic body 12 are set on a stripper 5, this stripper 5 floats up with the opening force of the elastic body 12 from the material to be worked 6 before the punch 3 reaches to the top dead center at the pressurizing ram elavating time and just after the top end of cutting edge of the punch 3 is pulled out from the material 6 to be worked 6, and it can be transferred to the next punching work without flow by rolling of the spherical rotary body 10 on the moving case of the material 6 to be worked.
