在生产中经常会遇到如图1所示一类的带凸缘环形件,采用锻造—机械加工的方法是能够加工出合格环形件的,但任务难度大、生产效率低、生产周期长、材料利用率低、成本高。东安发动机公司航发厂采用如图2所示的焊接—旋压工艺来加工环形件,工装数量少而简单、材料利用率高、对设备要求不高、成本低。 Often encountered in the production of a class shown in Figure 1 with a flange ring, the use of forging - machining method is able to process qualified ring, but the task is difficult, the production efficiency is low, the production cycle is long, Low material utilization and high cost. Dongan Engine Company Aerospace Factory uses the welding - spinning process shown in Figure 2 to process the ring, a small number of tooling and simple, high material utilization, less demanding on the equipment, low cost.
