基于Deform-3D的齿轮箱输出轴锻造成形研究

Research on Forging Process for Gearbox Output Shaft Based on Deform-3D

大型齿轮箱输出轴属于大型轴类锻件。针对某齿轮箱输出轴锻造质量不高的问题,提出了两次镦拔成形工艺,并运用有限元软件Deform-3D对其锻造工艺进行了数值模拟。结果表明,采用两次镦拔工艺,可以得到质量更佳的输出轴锻件。

The gearbox output shaft belongs to heavy axial forging. Aiming at problem of the bad quality of the forging for the gearbox output shaft, the two times upsetting and stretching were proposed, and the forging process was simulated by Deform-3D. The simulated results show that two times upsetting and stretching can obtain output shaft forging with good quality.
