Abstract：

Based on the analysis of the structural features and difficulties in forming for alternator claw poles, the warm and cold precision forming process was put forward. A finite element model was created for the critical bending process by the software Deform-3D. The results show that corner cutting, two direction corner cutting and rectangular billet experience the same two-stage process of bending and reverse extrusion during the blending process; the forming load of corner cutting billet is moderate and the tooth is well filled. At last, a well tooth filling forging without overlap defects was obtained by the forming experiment, which verifies the feasibility of warm and cold precision forming.
