许多研究者对剪切旋压过程的分析做了一些工作。但他们的作品在一定程度上是有限的。本文通过对铝合金剪切旋压过程的实验研究，详细了解了铝合金剪切旋压的基本特征。讨论了轧辊位置角、轧辊与芯模间隙、轧辊进给量、圆锥角、芯模转速、轧辊圆角半径、轧辊直径、坯料厚度和坯料直径等工艺条件对成形的影响。此外，还对由实验观测所得的简单剪切变形理论进行了切向力Pθ的检验。指出存在一个最佳毛坯厚度ts，其计算值与实验值吻合较好，当毛坯厚度小于ts时，理论值偏高，反之则偏低。
Many researchers have done some work on the analysis of shear spinning process. But their works are limited to a certain extent. This paper deals with the experiment on the shear spinning process of aluminium to find out the fundamental characters in detail. The influence of the following working conditions is discussed ; roller position angle, clearance between roller and mandrel, feed of roller, cone angle, speed of rotation of mandrel, roller corner radius, roller diameter, blank thickness and blank diameter. In addition, the deformation theory of simple shear which is derived from the observation of the experiments, is checked about tangential force Pθ. It is said that there is an optimum blank thickness ts, of which the calculated values agree with the experiments, and if the blank thickness is smaller than ts, the theoretical value is overestimated, but underestimated, if it is the other way round.
