摘　　要：分析了某汽车半轴的摆辗成形工艺,提出了工艺优化设计方法。结合零件的特点,设计了鼓形毛坯,保证了零件的顺利填充;设计了组合式凹模结构,并就凹模寿命进行了分析。结果表明,合理设计、制造及使用模具可以有效提高摆辗模具寿命。The swing forging process of the auto semi-axle was analyzed. The optimization design method was put forward. Combined with the characteristics of parts, the drum shaped blank was designed to ensure the favorably filling parts; the combination die sa＇ucture was designed and the combination die life was analyzed. The results show that the reasonable design, manufacture and application of the die can effectively improve the swing forging die life.
