School of Metallurgical Engineering, Xipan University of Architecture and Technology , Xipan 10055, China) Abstr ct: In order t o get alternator poles forgings w ith less cutt ing w ork, based on the analysis of traditional forming technology and the structure of alternator poles, a single stage closed die hot forging process and forming t ool-set of al- ternat or poles were put forward. A 3-D coupled thermo-mechanical finite element model w as created, w hich was ana- lyzed by the software Deform-3D. The billet deformation, metal flow and forming load were obtained. T he result s show that the single closed die hot forging process of alternator poles is practicable.
