The Optimum of Clearance for Mold in the Piercing Process with Finite Element Method

Abstract:

Present work describes a piercing process in order to investigate the clearance of mold parameters and to obtain optimal clearance values for a given sheet material and thickness to be pierced, using the finite element method. The clearance was studied by simulating the piercing operation of a Q235-B sheet. The results of the present paper showed that clearance was the most influential factor for piercing, and numerical experiments was an effectiveness method to get optimal parameters of mold parameters, and the numerical experiment results showed that the best clearance could be got when the ratio of clearance and thickness of material was 0.11.
