辊锻是近几十年发展起来的一种锻造新工艺,其原理是使坯料在一对旋转的轧辊中通过,借助装在轧辊上的圆弧形模具型槽,产生塑性变形,得到我们所需要的锻件。根据坯料送进方向可分为逆辊和正辊(如图1)。这种方法目前国內外多用于模锻前的制坯,或制造零件精度要求不高,形状较简单,如锄头、钉耙类的工件。用于要求高精度、形状复杂的零件较少。

Roll forging is a newly developed forging technology developed in recent decades. Its principle is that the blank passes through a pair of rotating rolls, plastic deformation is generated by the arc-shaped die-shaped groove on the roll, Required forgings. According to the feed into the blank can be divided into reverse roll and positive roll (Figure 1). This method at home and abroad are mostly used for pre-die billet, or less precision parts manufacturing requirements, the shape is relatively simple, such as hoe, nail rake class workpieces. Used to require high precision, less complex parts.
