Quick-edging rail-burning-free steel rail grinding wheel
The invention discloses a quick-edging rail-burning-free steel rail grinding wheel which comprises an aluminum alloy base body and a grinding body, the grinding body is sleeved with a glass fiber reinforcement layer, and the grinding end face of the grinding body is provided with protrusions and chip containing heat dissipation grooves. According to the grinding wheel, the structure of the grinding end face of the grinding wheel is designed, and the protrusions and the chip containing heat dissipation grooves are formed in the grinding end face of the grinding wheel, so that heat dissipation can be accelerated through the chip containing heat dissipation grooves in the grinding end face even if the grinding end face of the grinding wheel is not edged in the steel rail grinding initial stage of a new grinding wheel, the bluing phenomenon of a steel rail is solved; meanwhile, heat generated in the grinding process can be reduced through the protrusions on the grinding end face; and under the same grinding pressure, the protrusions structure is adopted on the grinding end face of the grinding wheel, so that the stress area can be effectively reduced, a binding agent on the surface layer of the protrusion structure can bear higher pressure intensity, and therefore, abrasive particles can rapidly fall off and be exposed, and rapid edging of the new grinding wheel is realized.
本发明公开了一种快速开刃不烧轨钢轨打磨砂轮，包括铝合金基体和磨削体，在磨削体外套设有玻璃纤维增强层，所述磨削体的打磨端面具有凸起和容屑散热槽。与现有技术相比，本发明的积极效果是：本发明通过对砂轮打磨端面的结构进行设计，在砂轮打磨端面设置凸起和容屑散热槽，使得在新砂轮钢轨打磨初始阶段，即使砂轮打磨端面未开刃，也可通过打磨端面的容屑散热槽加快散热，解决钢轨发蓝现象；同时通过打磨端面的凸起，可以减少打磨过程中的热量产生；且在同等打磨压力下，本发明通过在砂轮打磨端面采用凸起结构，能够有效减少受力面积，使凸起表层结合剂承受更大压强，从而快速脱落露出磨粒，实现新砂轮快速开刃。
