The Optimal Design of Cold Extrusion Die and its Realization

Abstract

According to the structure optimization of combined extrusion die, using finite element method to establish parametric model and optimize the combination die, compare the results with the result of Lame formula to prove the correctnesss of finite element method; and adjust the structure of concave of die basing the optimal result, so as to reduce the stress concentration and the maximum equivalent stress value on the concave mould, and thus the life-span of the die is prolonged.
