Continuous stamping simulation and wear analysis of die considering milling surface topography

In this study, we analyzed the internal influence of the number of stamping on die wear through equivalent continuous stamping simulation and explored the wear state of the die at different stages before the die loses dimensional accuracy. First, the largest wear part of the mold was studied through simulation and experiment. The results showed that the maximum wear value appeared at the fillet of the bottow die. Second, according to the surface topography of the milling mold, the residual height of the topography under the conventional milling parameters was determined, and the residual height is accurately divided according to the difference in the shape of the contact surface. Finally, an equivalent continuous stamping simulation was performed on the mold with surface topography, and the internal influence of stamping times on mold wear was found. This work provides a theoretical method for analyzing the wear resistance of the mold and the production of the mold.
