Abstract

Aiming at the problem of short service life of a rivet nut die for an automobile, this paper analyzes the problems existing in the existing production scheme and puts forward an optimized cold heading forming scheme, that is, to reduce the die stress at the corresponding station by transferring the deformation of important stations. The optimum combination of forming process parameters was obtained by orthogonal test design method. By means of numerical simulation and experiment, the cold heading scheme and process parameters were verified. The results show that the optimized scheme and process parameters can effectively reduce the die stress and prolong the die life.
