摘　　要：根据小直径超薄壁柱形筒体的结构特点,采用错距、正向旋压加工方法,制定出三种旋压毛坯工艺方案并列试验,经过旋压工艺验证,优选出采用5mm厚旋压毛坯两道次旋压成型的工艺为最佳方案,与其它两种方案相比,其优点为工序少、产品精度高、经济效益好。The stagger forward spinning technology is adopted according to the structural characteristic of a small diameter super-thin cylindrical tube. Three kinds of the spinning forming processes of roughcast are simultaneously tested. By the spinning forming process validation, the optimal scheme is the processing of 5mm roughcast two-pass spinning forming. Contrast to the other two schemes, its advantages are simple working procedure, high precision and low cost.
