摘要
目的解决由回弹引起的机械式胀形桥壳形状尺寸不精确的问题。方法采用Marc软件平台和物理实验相结合的方法展开研究,运用补偿法对模具进行修正,补偿回弹量。结果机械式胀形过程中,桥壳回弹量较大,单侧回弹量达到6.06 mm,严重影响其形状尺寸精度。结论通过对模具进行适当修正,桥壳回弹量得到了很好补偿,成形效果较好,得到了符合要求的桥壳零件,进一步完善了该工艺的理论基础。
Objective To solve the inaccuracies in shapes and sizes of mechanical bulging axle caused by springback.Methods The research was conducted by the combined method of Marc software platform and physical experiments,using a compensation method to repair the mould to compensate the springback. Results The axle housing had a large springback,and the unilateral value reached 6. 06 mm which would seriously affect the accuracy in the shape and size of the axle housing. Conclusion The numerical simulation and experimental results showed that the forming effect was much better,and the springback was better compensated,which met the requirements of the axle housing parts. Meanwhile,the theoretical foundation of this process was further improved.
