Study on new rotary rolling technology and die life of auto semi-axle

The principles and features of auto semi-axle pendulum rolling technology are introduced. It has made a comparison with the mould forge technology on the aspects of the production process, cost, the labour intensity, the quality of parts, the production efficiency and the working environment. The weakness of the fomer technological process for manufacturing the BJ130 automobile semi axle is analysed. A new process of pendulum rolling for the semi axle is proposed. The selection of the manufacturing equipment and the key points of the design of the die are introduced.
