对某种柔性的薄壁TC2钛合金异型环,传统的制造工艺由下料、拼焊、成形、机械加工、表面处理等工序组成。针对该工艺流程繁复、制造成本高的问题,提出一种不用成形的快速制造方法。该方法利用异形环平直母线可精确展开的特征,对其不同半径的锥面逐步展开后合理叠加成精确的展开图形,依图形下料并对焊成环。此方法仅需下料和焊接,无需成形和机械加工,流程简单,为该类零件的低成本、快速制造提供了新途径。
For a flexible thin-walled TC2 titanium alloy shaped ring, the traditional manufacturing process consists of cutting, welding, forming, machining, surface treatment processes. In view of the complicated process and high manufacturing cost, a rapid manufacturing method without forming is proposed. The method utilizes the characteristic that the straight bus bar of the shaped ring can be accurately expanded. The tapered surfaces with different radii are gradually unfolded and then formed into a precise unfolding pattern. This method requires only blanking and welding, without forming and machining, simple process, and provides a new way for low-cost, rapid manufacturing of such parts.
