椭圆截面轴类零件的楔横轧轧制理论

Rolling Theory of Ellipse Profiles Shaft on Cross Wedge Rolling

非回转体零件在机械工业中有广泛应用,迫切需要一种新技术、新工艺来实现其轧制生产。因此,利用非回转体的节曲线封闭条件理论、瞬时传动理论等原理。推导了以极坐标表示的椭圆轧件楔横轧轧制曲线方程,为轧件成形提供了理论依据,扩展了非回转轧件轧制的范围。

Non-circular parts have been used extensively in mechanical industrial field. Thus, it is very urgent to apply new technology and new process to produce these kinds of components by cross wedge rolling. This topic mainly makes full use of the theory of node curve in closed condition and theory of instantaneous transmission to ratiocinate the rolling curve equation of the ellipse in polar coordinates format. This equation gives the theory basis for the parts in using polar coordination format and enlarges the rolling range for non-circular parts.
