摘要 常用的滚轮毛刷钝化设备在抛光钝化硬质合金刀片切削刃时存在切削刃圆弧半径及大小不均匀问题。文章基于滚轮毛刷钝化设备的工作原理,从毛刷运动及毛刷磨损两个方面分析造成硬质合金刀片切削刃钝化圆弧半径及大小不一致的原因,通过对设备运动方式进行数学建模,计算得知:产品进入毛刷和离开毛刷期间,产品自转的圈数不是整数,则会造成产品某一个角或者某一条切削刃加工时间更长;同时毛刷磨损的不确定性也会造成实际加工时间的差异,造成切削刃圆弧半径及大小不一致乃设备设计的缺陷,不可避免。 In this paper,the problems of uneven arc radius and size in polishing and passivating the cutting edge of the cemented carbide blade by commonly used roller brush passivation equipment were analyzed.Based on the working principle of roller brush passivation equipment,this paper analyzed the reasons for the inconsistent arc radius and size in passivating the cutting edge of cemented carbide blades from two aspects of brush motion and brush wear.Through the mathematical modeling of the equipment movement mode,it is found that when the product enters the brush and leaves the brush,the number of product rotations is not an integer,which will result in a longer processing time for a certain corner or a certain cutting edge of the product.At the same time,the uncertainty of brush wear will cause a difference in the actual processing time,which causes the inconsistency of the arc radius and size of the cutting edge.This is the inevitable defect of the equipment design.
