Abstract：

In order to get alternator poles forgings with less cutting work, based on the analysis of traditional forming technology and the structure of alternator poles, a single stage closed die hot forging process and forming tool-set of alternator poles were put forward. A 3-D coupled thermo-mechanical finite element model was created, which was analyzed by the software Deform-3D. The billet deformation, metal flow and forming load were obtained.The results show that the single closed die hot forging process of alternator poles is practicable.
