Research on Warm-Cold Precision Forging Process and Numerical Simulation for Spherical Housing
The warm-cold forming process is researched for complex-DOJ-type spherical housing by means of numerical simulation. Each step of the process is simulated, especially for the reverse extrusion process. Focusing on analysis of the material flow, temperature distribution as well as the load curve, a reasonable process for DOJ-type spherical housing is obtained. The reasonable forming process for DOJ-typed spherical housing offers favorable basis for forming and mold design.
