第六章 锉削与光球 一、加工原理及加工规范 1.锉削加工 将有环带的冷镦球坯或除去环带后的热镦球坯放在两块带有锉齿的锉盘之间加工,称锉削,如图6-1所示。锉削时,下锉盘转动,上锉盘不转动;球坯一方面受到下锉盘旋转离心力的作用,向外径方向移动,另一方面在工作压力P以及下锉盘的转动作用下,既滚动又作微量自转,从而使其表面反复受到锉齿的挤压和锉削。锉削过程大致如下:首先,在球坯表面上挤压出错综复杂的锉齿牙痕,接
The sixth chapter filing and light ball First, the processing principle and processing specifications 1 file processing will have ring cold heading ball blanks or remove the ring after the hot upset ball billet with two file rasp gear Between the processing, said file cut, as shown in Figure 6-1. When the file is cut, the file tray is rotated and the upper file tray is not rotated; on the one hand, the blank is moved to the outer diameter by the centrifugal force of the lower file tray, on the other hand, under the action of the working pressure P and the rotation of the lower file tray, Both rolling and trace rotation, so that the surface repeatedly by the file extrusion and filing. File cutting process is as follows: First, squeeze the surface of the ball blank intricate filing teeth trace, then
