Abstract
In this paper, a finite element analysis model including Archard wear model of the rotary forging process for auto semi-axle is presented. Based on the software of Deform-3D, this analysis investigates the temperature and wear changing rule during forging. Different initial die hardness and friction factor were selected respectively to simulate rotary forging processes, which initial die hardness from 40 HRC to 65 HRC that the equal increase is 5, and friction factor from 0.15 to 0.5 that the equal increase is 0.5.The results show that the maximum temperature are appeared on the transition fillet of the die and punch, and the peak temperature was 599℃. The die wears decreased rapidly with the hardness raised and the friction factor declined. The highest temperature and seriously wear position are in the transitional zone of the flange.
