The utility model discloses a grinding and polishing brush with a high-strength grinding wire bundle, which is characterized in that a grinding wire bundle fixing plate matching the shape of the brush holder is arranged on the brush holder, the edge of one end face of the grinding wire bundle fixing plate extends axially, the grinding wire bundle fixing plate is evenly provided with a grinding wire bundle perforation, and the grinding wire bundle is worn. One end of the hole is chamfered, the grinding tow is pierced in the hole, the resin glue is filled between the grinding tow at the chamfered end, and the brush holder is fixed between the grinding tow fixed plate. The resin adhesive has a larger contact area between the fixed plate of the grinding tow and the grinding tow after being cured in the perforation hole of the large chamfered grinding tow. The bonding between the fixed plate of the grinding tow and the grinding tow is stronger. The tensile strength of the brush wire is increased at least twice, the weight of the product is reduced by more than 35%, and the utilization ratio of the grinding brush wire is increased. The product cost is effectively reduced. The smoothness of the brush wire is increased to 95%. After the brush wire is worn out, the fixed plate of the grinding tow can be separated from the base and the base can be reused.

一种具有高牢固度研磨丝束的研磨抛光刷
本专利技术涉及研磨磨具。
技术介绍
研磨刷是与机械设备配合使用的研磨器具,它是由底座和研磨丝两部分组成,底座和研磨丝间通过卡子、码钉或胶水将两者接合在一起。研磨丝是在尼龙基体内混入金刚石或碳化硅等高硬度粉末磨料制成。这种研磨刷广泛用于石材、金属板材、太阳能等行业领域的产品表面研磨加工。传统的研磨刷是在底座上开设若干安装凹槽,在各凹槽内固定研磨丝,这种研磨刷在研磨加工时,研磨丝端部通过对材料表面进行磨蚀而研磨出需要的表面效果。传统工艺固定研磨丝的方式分为卡子、码钉或在凹槽中挤入胶水将研磨丝固定,通过卡子、马钉固定研磨丝的研磨刷,凹槽深度需达到8mm以上才可起到固定研磨丝的作用;而通过胶水固定研磨丝的研磨刷,其凹槽深度需达到10mm以上才可起到固定研磨丝的作用。这两种传统结构的研磨刷都存在下述不足:1、刷丝牢固度不够,植毛强度不易控制;2、植丝孔需达一定深度,且孔深必须要大于或等于孔径,否则会严重影响刷丝的牢固度;3、由于传统钉制的研磨刷刷托易变形,从而影响与刷丝间的连接及研磨刷外形;4、植丝完成后要将参差不齐的刷丝进行平毛;5、研磨加工废弃后的研磨刷因刷丝无法从刷托上取出而使得刷托不能得到回收利用。
