摘　　要：针对传统锻造方法加工出的锻件尺寸散差、椭圆度、锥度大的情况,设计出整径工装及模具,提高了锻件尺寸精度和材料利用率,满足轴承市场需求。Aiming at the big dispersion error, ellipticity and conicity of the forgings produced by traditional forging method, the tooling for finishing hole and outer circle shape and die is designed. By this new method, the dimensional accuracy and stock utilization is increased so as to meet the need of bearing market.
