Abstract：

For the mold wear problem of pin shaft during warm upsetting, the forming process of non-standard pin shaft was simulated by finite element software Deform-3D based on revised Archard wear theory, and the forming effect and die wear were simulated and analyzed from multiple aspects such as stress distribution and forming load, etc. Then, aiming at extending the service life of mold, the key process parameters in the forming process were optimized by response surface method, and the influence rules of each parameter on the die wear were obtained, and the optimal process parameters were the stamping speed of 5 mm·s-1, the billet heating temperature of 600 ℃, the mold preheating temperature of 280 ℃. Furthermore, the actual mold trial was conducted by the optimized process parameters combination, and the part forming effect was good. At the same time, the wear morphology distribution on the mold surface was obtained by scanning electron microscope, and the actual wear of die was basically the same as the simulation result, which verified the correctness of the simulation and optimization results.
