| 摘 要： | 精锻方法成形螺伞齿轮与机加工齿轮相比具有力学性能好、寿命长、材料利用率高等优点.本文开发了一种采用“镦粗—预锻—冲孔—终锻”流程成形从动螺伞齿轮的热精锻工艺方案,针对该工艺方案设计了中心分流的闭式精锻模具,利用有限元分析软件Deform-3D进行工艺流程数值模拟,得出填充情况、成形载荷、齿廓纤维流向等重要信息.在1000 t离合器式螺旋压力机上试制出直径为165mm的螺伞齿轮锻件,验证了工艺方案的可行性及有限元模拟的正确性,为螺伞齿轮精锻成形批量生产提供了借鉴. |

| Abstract: | Compared to traditional machined spiral bevel gear,the hot precision forged one has better mechanical property,longer service life,less material consumption and other advantages.A hot precision forging process consist of upsetting,pre-forging,wed punching and finish-forging was developed,and a set of closed precision hot forging die with a pothole in the middle to divide metal flow was designed.The FEM software Deform-3D was applied to predict some important information during the forging process,such as material flow,forging load,grain flow orientation etc..Spiral bevel gear with diameter of 165 mm was successfully forged on 1000t clutch operated screw press,thus the feasibility of the process and the validity of numerical simulation were proved.This may provide useful guidelines and reference for further research and mass production. |
