摘要：

为了得到少无切削的爪极锻件，在对爪极零件传统成形工艺和零件结构分析的基础上，提出了爪极闭式热锻一步成形工艺及对应的模具。建立了关于该成形工艺的三维热力耦合有限元分析模型，并通过Deform-3D对其进行了热模拟，得到了变形过程的坯料变形、材料流动情况和载荷行程曲线，结果证明了爪极闭式热锻一步成形的可行性。

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.
