| 摘 要： | 本文对钛合金半环的超塑成形技术进行了工艺研究。采用正反胀形方法来控制成形后半环的壁厚,并通过数值模拟手段,对壁厚控制的关键即正反胀形模具型面进行了优化设计,同时进行了试验验证。结果表明数值模拟数据较好的预测了超塑成形后的半环壁厚分布,利用优化后的正反胀模具实现了半环试验件的壁厚均匀化。该方法能够明显提高材料利用率和后续车加工效率,并降低制造成本。

| Abstract: | SPF process for titanium semi-annular part had been researched in this article. A direct-reverse SPF process was intended for controlling the thickness of the semi-annular part after forming,and the SPF forming die which is the key for the thickness control had been designed and optimized by numerical simulation method.Verification experiment was preceeded for a TC4 semi-annular part,the results show that the actual thickness distribution of the part can be well predicted by the numerical simulation,the thickness of the part was homogenized by using optimized SPF forming die.This process can not only improve material utilization ratio and efficiency of subsequent processing,but also reduce total manufactuting costs. |
