五、旋压工艺 1、旋压加工的分类旋压加工的过程可以归纳为:利用一个或多个成形滚轮(或者滚珠、或者赶棒),在相对旋转和彼此进给两种运动复合作用下,通过滚轮的轧压,使被加工毛坯逐点产生塑性变形,或改变形状(壁厚基本不变),或减小壁厚,或两者兼而有之。大多数情况下,旋压加工要采用一个芯模,以便把毛坯加工成与之相应的形状和尺寸。这个过程在国外有许多种名称,尚未统一。如剪切旋压(Shear spinning和しごき V. Spinning Process 1. Classification of Spinning Process The process of spinning process can be summed up as follows: the use of one or more forming rollers (or ball, or catch rod), in the relative rotation and feeding each other under the action of two kinds of sports , By rolling the roller, so that the processed blank by plastic deformation point by point, or change the shape (the same wall thickness), or reduce the wall thickness, or both. In most cases, a mandrel is used in the spinning process to machine the blank into the shape and size corresponding to it. This process has many kinds of names in foreign countries, not yet unified. Such as shear spinning (Shear spinning and し ご ki
