摘　　要：介绍了一种材料为合金结构钢30Cr Mn Si A的双台阶固体火箭助推器壳体强力旋压工艺方法。通过分析零件的结构特点,确定出采用正向旋压方法,设计相应的旋压毛坯和旋压工装。通过工艺试验过程检测与数据分析,确定出合理的旋压工艺流程,经过生产验证旋压工艺流程的合理性和可行性,旋出满足设计要求的产品,为同类结构壳体旋压提供技术参考。This paper introduces a kind of double-step rocket booster whose case is made from structual alloy steel 30 Cr Mn Si A and formed by means of shear spinning. By analysing the structual character of the component, forward stroke spinning has been chosen and corresponding blank and auxiliary assembly have been designed. By analysing the data and testing the process, rational spinning process has been ascertained. the rationality and practicability have been tested by producing, and the products can satisfy the demands. This can provide technological reference for case spinning of similar construction.
