The FEM Simulation of the Pressure and Fine-Blanking Quality
A numerical model research of fine-blanking has been built up. The fine-blanking process of parts with pressure is 0KN20 KN40 KN60 KN respectively , thickness of plate 2.9mm and diameter 16mm,of steel 45, has been simulated. Through simulation, the study gets the material distribution situation of mean-stress fields in the progress of fine-blanking, and analyzes the relation between mean-stress fields and the crack of shearing zone. And get the pressure optimization value.
