摘　　要：利用Deform软件,对不同的飞边槽结构对曲轴预锻成形中坯料的充填情况及成形载荷的影响进行了分析.通过在飞边槽桥部合理增设阻力沟或阻力墙,使得曲轴预锻模膛W1平衡块未充满的高度由8.33 mm减少到1.33 mm,对曲轴平衡块的充填性有了很大程度的改善,且优化了毛坯尺寸.Based on Deform software, the influences of different types of flash slots on the blank filling and the forging load of crankshaft were studied. By adding reasonable resistance ditch and wall on the bridge of flash slot, empty height of the crankshaft balance blocker W1 was finally reduced from 8.33 mm to 1.33 mm,which had greatly improved the filling of crankshaft balance block and optimized dimensions of the blank.
