Abstract

A finite element analysis has been performed to investigate the effect of v-ring indenter on the sheared surface in the fine blanking of a pawl which is a part of the automotive safety belt and is made of S45C sheet. In the present analysis the Cockcroft and latham fracture criterion and the element kill method are used in order to simulate the blanking operation successfully. The simulation results are obtained for various positions and heights of the v-ring indenter. And the theoretical results are compared with available experimental results. It is shown that this FEM simulation result can be useful for predicting the optimal fine blanking condition of real products.
