Article Preview

An optimum process for a two-step press forging of stepped holes in a metal sheet was proposed .Numerical simulation on the two-step process was carried out by using DEFORM-3D. Distributions of effective strain and effective stress were obtained. The study showed that the process not only can form the stepped, but also can increase the surface quality and strength of stepped holes in sheet metal parts, According to the numerical simulation’s process parameter , an experimental die was designed, the simulation results were in good agreement with the experimental data
