Abstract：

The auto semi-axles are formed by two steps in an auto parts factory in our country,they are preforged on a press and finished on a rotary forging machine,and the semi-axle blanks need to be heated twice,which brings great consumption of raw materials and high production cost.For this situation,a new precedure called combined forming of upsetting and rotary forging for auto semi-axle formation was introduced,the forging force as well as other technical parameters for forming EQ153 semi-axle were calculated,and a 250 t upsetting and rotary forging machine with special feeding slide structure was designed,which could accomplish the part formation by one step.
