Abstract

In order to improve the surface quality of the cold roll-beating workpiece and explain the surface hardening behavior of the workpiece, an experiment on the microhardness and scanning electron microscopy of a cold roll-beating workpiece was carried out by using involute spline as the subject. The changes of the hardness of the splines at different positions under the same process parameters were analyzed, and the changes of the surface hardening degree and the microstructure of the splines under different process parameters were discussed. The results show that the surface hardness of the tooth top, index circle and tooth root under different process parameters decreases with the increase of the distance from the tooth surface. The degree of hardening of the spline surface, at the same rotate speed, increases as the feed rate increases and at the same feed rate, it decreases as the rotate speed increases.
