挤齿代替剃齿的工艺近年来在国外逐渐得到推广采用。这里介绍西德最近发展的一种单轮挤齿工艺。文中所介绍的单轮冷挤机主要特点是轧轮轴与工件轴的相对高度保持不变,工件依轧轮的切线方向作进给;有利于提高定位精度,增强机床刚性和简化机床结构。单轮冷挤法对于齿轮的精整无切削加工工艺具有一定的参考价值。这种方法与我国现有冷挤工艺相比较,其技术经济效果如何,还有待于研究。
In recent years, the technology of extruding teeth instead of shaving has been gradually popularized in foreign countries. Here introduced a recent development of West Germany, a single wheel extrusion process. The main features of the single-wheel cold extrusion machine introduced in this article are that the relative height of the spindle and the workpiece axis remains unchanged, and the workpiece is fed according to the tangential direction of the rolling wheel; it is beneficial to improve the positioning accuracy, enhance the rigidity of the machine tool and simplify the structure of the machine tool. One-wheel cold extrusion method for the gear finishing without cutting process has a certain reference value. This method compared with the existing cold extrusion process in our country, its technical and economic effects, yet to be studied.
