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-rotating parts in the machinery industry has a wide range of applications, an urgent need for a new technology, new technology to achieve its rolling production. Therefore, the non-revolving body section curve closed condition theory, instantaneous transmission theory and other principles. The curve equation of cross wedge rolling of elliptical rolling in polar coordinates is deduced, which provides a theoretical basis for the forming of rolling stock and extends the rolling range of non-rolling rolling.
