本文讨论了普通旋压中罗拉道次的确定问题.通过合理的轧辊道次制度来控制坯料的变形方式，以避免板料起皱或断裂。首先，作者尝试了四种基本类型的模板，即线性形状模板（旋转和内移型）和圆形形状模板（外移和内移型）在钣金件中的绘制。根据实验结果，提出了一种渐开线型面样板。试验结果表明，这种新型渐开线样板可以通过改变工作条件自由控制旋压杯的高度，提高极限拉深比。当t0/d=1.25时，拉伸倍数为2.5。
This paper deals with the decision of pass schedule of roller in conventional simple spinning. It is important to control the deformation mode of blank by an excellent pass schedule of roller, lest the sheet metal should be wrinkling or fracturing. At first, the authors attempt to draw in sheet metal by four fundamental types of template, namely-linear shape template (revolved and inside shifted type) and circular shape template (outside and inside shifted type). From the experimental results of these types, an involute curve is proposed for the profile of template. According to the test result of the new involute template, it is evident that the height of spun cups can be controlled freely by the alteration of working conditions, and the limit drawing ratio is best improved. The authors obtain the drawing ratio of 2.5 when t0/d=1.25.
