摘要：金属旋压是一种适用于生产薄壁回转体工件的成形工艺，采用旋压的方法加工维体盒形件的成形工艺一直是研究的重点和难点。为了拓宽视野，采用定初始角度步长无模空心能压旋轮路径设计的方法进行旋压工艺的设计。通过维体盒形件的几何关系分析推导出旋压路径，并将旋压路径转化成数控机床程序代码，从而完成锥体盒形异形件的加工，得到了符合加工要求的零件，并且表面没有起皮、波纹、鼓包、裂纹等常见缺陷。

Sehool of Mechanical Engineering, Northwestem Polytechnical University, Xi'an 710072, China) Abstract: Metal spinning is a kind of forming process which is suitable for forming thin wall revolving body. The forming process of conc box shaped parts by spinning has been the focus and the dificult point in research. In order to broaden the horizon of research, the spin ning process was designed by the step-length method with fixed initial angle to produce a roller path of the hollow spinning without die Then, the roller path was deduced by analyzing the geometry relationship of the cone box shaped parts and tumed it into NC code to finish foming, Thus, the part made by this method meets the requirements without other eommon surface defects such as skin, ripple, bulging, and cracks.
Key words: asymmetrical part; cone box shaped parts; step-length method with fixed initial angle; hollow spinning without die; roller path
