| 摘 要： | 为改善直齿内齿轮零件采用常规闭式镦挤成形时载荷大、型腔充满困难、模具磨损严重等情况，本文在分流锻造法的基础上，采用二次分流的方法，提出了直齿内齿轮的两段成形的精密锻造成形新工艺，即缩挤和镦挤相结合的成形工艺。并用有限元软件对直齿内齿轮的两段成形工艺进行数值模拟，分析、验证了该工艺的可行性。

| Abstract: | Based on the forging principle of divided-flow and with the method of secondary divided-flow, the two-stage forming technology of cylindricalstraight inner gear was put forward.The technology combinedthe extrusion forming andthe upsetforming. Then the numerical simulation with FEM simulation software proves the feasibility of the new technology. |
