Abstract：

For the automobile aluminum alloy protective cover, the mold wear problem in the forming process was studied. Firstly, based on the Archard modified model, the hot forging process was modeled and simulated by software Deform-3D, the wear conditions of punch and die were analyzed, and the wear of die was much greater than that of punch. Secondly, taking billet temperature, mold temperature, die hardness, forging speed and friction factor as the research factors, the orthogonal test simulation was carried out. Furthermore, taking the wear depth of die and the load on the die as the optimization objectives, the optimal combination of forging process parameters was obtained by the weighted analysis method combining with range analysis method. The results show that the service life of the optimized die is increased by 50.9%, and the simulation results are verified by production tests, showing the actual life of the die is close to the simulation results. Thus, the finite element simulation can be applied to study the life of mold.
