| 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.

| 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 alterna... |
