摘　　要：针对某规格无相位角四拐曲轴的"平衡块难以成形"的特点,提出了一套制坯后直接终锻的生产工艺流程。利用数值模拟软件,通过优化制坯与优化模具结构相结合,实现了省略预锻工序的目的。分析看出,常规飞边槽结构的成形效果很差,直线型阻力墙不能解决充填问题,而采用随形阻力墙结构则具有很好的成形效果。According to the shape character of some one none-phase angle crankshaft, a production process characterized by direct final forging after making process was brought forward. Based on simulations the pre-form step was skipped through optimizing making process and mould structure. The results show that the forming impression of mould with common flash gutter works out badly, while linear pattern resistance wall could not solve filling problems. Whereas, the resistance wall following part achieves good simulation result.
