Abstract：

Based on the software of Deform, the technology of hot rotary rolling for auto semi-axle was studied, and the distribution and change regulations of equivalent stress were mainly analyzed. The results show that the maximum deformation appears in the area of flange and transfers to the bottom of the part, and the maximum effective stress increases from 193 MPa at the initial stage to 302 MPa at the end stage. When the friction coefficient increases from 0.1 to 0.5, the maximum effective stress increases from 235 MPa to 304 MPa, and the deformation extent can be reduced effectively by wiping lubricants such as MoS2 or oil on the lower surface of the die during the forming process.
