摘要：

主要对外径Ф300 mm、带3处外台阶的C250马氏体时效钢薄壁壳体旋压加工进行工艺研究。针对马氏体时效钢时效处理后会产生收缩的特性，通过实验统计出Ф300 mm、壁厚2～3 mm旋压壳体时效后的收径量。因此在旋压壳体加工时，预留出时效后的收径量，待时效处理后达到最终设计技术指标。结合C250马氏体时效钢的材料性能与零件结构特点进行分析，确定采用多道次正旋压方案。验证了Ф300 mm壳体在不进行中间热处理加工和80%总变形率的条件下，直径公差0.32 mm与壁厚公差0.1 mm的高精度壳体成形的可行性。

The spinning process of thin-walled C250 maraging steel shell with 300 mm outside diameter and three outer steps was investigated. Aiming at the shrinking characteristic of maraging steel after aging treatment, the amount of reduced diameter of spinning shell with 300 mm diameter and 2-3 mm wall thickness was calculated by experiments. Therefore, the amount of reduced diameter of spinning shell after aging treatment which achieves the ultimate designed technical requirements was reserved during spinning. The multi-pass spinning program was determined by C250 maraging steel material properties combining with structural characteristics of parts. The feasibility of forming Ф300 mm high-precision shell with 0.32 mm diameter tolerance and 0.1 mm thickness tolerance was verified under the condition of without intermediate heat treatment and with the total deformation rate of 80%.
