摘要：

根据一种变速器行星架的结构特点，提出一种新的多向精密成形工艺，可一次性成形出带4个侧面方孔的行星架锻件。利用有限元模拟软件Deform-3D，对变速器行星架的多向精密成形工艺进行了数值模拟。分析了成形过程中的载荷-时间曲线、等效应力分布等，根据模拟结果设计了行星架多向精密成形模具结构，分析了关键模具部件的强度，最后进行了工艺试验。研究结果表明，提出的行星架多向精密成形工艺是可行的，模具结构合理可靠，试验得到的行星架锻件充填饱满、尺寸符合设计要求。对该类零件及其他相似零件的生产具有一定的指导意义。

According to the structural characteristics of a transmission planetary frame, a new multi-directional precision forming process was proposed. The planetary frame forgings with four side square holes could be formed at one time. The multi-directional precision forming process of transmission planetary frame was simulated by using finite element simulation software Deform-3D.The load-time curve and the equivalent stress distribution in the forming process were analyzed. Based on the simulation results, the multi-directional precision forming die structure of planetary frame was designed, and the strength of key die components was analyzed. Finally, the process experiment was carried out. The results show that the multi-directional precision forming process of planetary frame proposed is feasible, the die structure is reasonable and reliable, and the forgings of planetary frame obtained by the experiment are full filled and the size meets the design requirements. It has certain guiding significance for the production of this kind of parts and other similar parts.
