Abstract：

A reliable three-dimensional rigid-plastic finite element model for rotational fine blanking of helical gear was developed by the Deform-3D platform. Based on the Archard wear module, the wear analysis of die in the fine blanking process was carried out, and the wear distribution of points in the die working surface was obtained. Then, the maximum die wear range was determined, and the die wear characteristics of fine blanking of spur gears and helical gears were compared. Furthermore, the influences of ejector force, blank holder force, blanking speed, blanking clearance, fillet radius of bottom die, hardness of bottom die on die wear were studied. The results show that the relationship between die wear and process parameters are predicted by the above die wear model, and the solution that reducing die wear based on the process design is put forward.
