摘　　要：采用旋压成型T250马氏体时效钢双台阶筒形件,分析了材料特殊性和产品结构特点,确定采用错距正向旋压加工。通过合理设计旋压工装和旋压毛坯,经过旋压工艺试验,生产出满足要求的产品,得出T250马氏体时效钢多旋程旋压筒体最终道次缩径量比一次旋压成型筒体的缩径量小,为使用相同材料的同类件的旋压提供参考。Stagger forward spinning technology is adopted for the double-step tube of T250 maraging steel by analyzing the material characteristic and the corresponding product structure particularity.Through the reasonable design of spinning tooling and spinning roughcast as well as spinning technology experiment,the requirements of final production are met.It is concluded that reduction of the final pass of T250 maraging steel tube during muti-rotary spinning is smaller than that of one-step spinning forming tube.All these works provide a reference for spinning technology study of the same part with the same material.
