Abstract：

For the die wear of phosphorus bronze C5210R-EH sheet metal with thickness of 0.2 mm during blanking process, the contact friction in the process of blanking deformation was analyzed, and the punch wear was evaluated by the variation of Co element based on the skeleton theory and the compound strengthening theory. Then, the punch wear in the blanking process was simulated by DEFORM2D, and the change trend between the blanking process parameters and the variation of Co element as well as punch wear was studied. The results show that the wear amount at the end face of punch is much less than that of the side wall, and the wear depth of punch and variation of Co element decrease with the increase of die clearance depth, while they increase with the increase of stamping speed, as well as they decrease first and then increase with the increase of die fillet radius. Therefore, research results provide an evaluation method to predict the wear of stamping die.
