用滚压法使零件表面塑性形变,从而强化零件,目前正广泛应用于机器制造业中。传统的塑性形变方法,是滚压应力集中的表面(例如:齿根、孔、齿间等),从而使得许多情况下的劳动量非常繁重,而且需要专用的设备和工具。这里推荐的表面塑性形变方法,将用于只有角柱形状的零件(例如吊耳、盘板等),或者具有正圆柱形状 With the rolling method of plastic deformation of the surface of the parts, which strengthen the parts, is now widely used in machinery manufacturing. The traditional plastic deformation method is to roll stress concentrated surfaces (eg, root, hole, interdental, etc.), which makes the work in many cases very heavy, and requires special equipment and tools. The recommended method of plastic deformation of the surface is to be used for only prismatic-shaped parts (such as lifting lugs, disk plates, etc.) or having a regular cylindrical shape
