本文给出了纵向突变截面辊锻的基本方程,从理论上阐明了其精度不高及重复精度低的原因。指出了辊锻不同于锤或压力机模锻以及轧制的变形特点。
In this paper, the basic equation of roll forging with longitudinal section is given, and the reasons of low accuracy and low repetition accuracy are clarified theoretically. It is pointed out that the roll forging is different from the forging of the hammer or the press and the deformation characteristics of the rolling.
