摘　　要：介绍了O型环的结构特点,分析了常规工艺方法在产品成型过程中存在的不足,提出了采用拉弯成型工艺制造O型环,并由此制订了拉弯成形工艺方案。产品试制结果表明,制订的拉弯成型工艺方案可行,产品生产效率高,精度好,性能优良。The design feature of O ring was introduced. The shortage of conventional technique used in forming O ring was analyzed. The stretch bending technique used in forming 0 ring was presented. The process program of stretch bending forming was determined because of that. The results of trial manufacture showed that the process program of stretch ben- ding forming is feasible, the production efficiency is high, the products have good quality.
