摘　　要：针对数控旋压成形加工过程中的常见旋压缺陷及旋轮的常见失效形式,提出了一种蠕动式进给旋压加工的新工艺方法。在此基础上,对筒形旋压件进行了常规数控旋压成形加工和蠕动进给旋压成形加工对比试验。实验结果表明:新工艺显著提高了旋轮的使用寿命,减小了工艺系统的变形,提高了旋压件的加工质量;新工艺更适合硬度及变形抗力较低的材料的高精度旋压成形加工。Based on analyzing problems about several common forming defect and failure modes of roller in NC spinning,a novel precision spinning technique,creep-feed spinning process was put forward.On this basis,comparative experiments of spinning tube with/without creep feed were carried out.The experimental results show that the novel precision spinning technique can extend life of roller,reduce deformation of spinning process and achieve higher spinning precision;it is suggested that the technique is an optimum option for spinning workpiece with lower hardness and deformation resistance.
