Abstract：

Aimed at present domestic problems in the forging process of claw pole,such as insufficient corner filling,excessive forming force and short life of dies and on the basis of analyzing the claw pole,a new process named as closed hot die forging direct extrusion process for claw pole was constituted.The numerical simulation using DEFORM-3D and the special mould were used in the forging experiment in order to check the new process.The results show that new technology has greatly reduced the forming force and thereby the production procedure is reduced and the die life is improved for the mass production.
