Vibration grinding steel rail grinding method

Abstract

The invention discloses a vibration grinding steel rail grinding method, and belongs to the technical field of grinding. The method comprises the following steps that a, vibration is generated when a grinding wheel grinds a steel rail to form vibration grinding; b, a vibration generator is arranged at any position of a grinding wheel-main shaft system, and the vibration form, the vibration power, the amplitude frequency and the like are adjusted according to the grinding process requirements; and c, the vibration direction can be any direction such as the longitudinal direction, the transverse direction, the vertical direction and the inclined direction of the steel rail or the composite disordered vibration direction. According to the vibration grinding method, vibration is provided for the grinding wheel, the grinding efficiency and the feeding speed of the steel rail are improved, and the grinding depth is increased, so that the grinding efficiency is improved, the maintenance time is shortened, the grinding vibration effect is achieved, the grinding force is reduced, meanwhile, the residual stress of the grinding surface is reduced, grinding burn is avoided, the surface quality of the steel rail is improved, and the service life of the steel rail is prolonged.

Description

technical field [0001] The invention belongs to the technical field of grinding, and in particular relates to a vibration grinding method for grinding steel rails. Background technique [0002] Rail transportation is an important component of my country's transportation system and one of the main modes of transportation. Rails provide guidance and transfer loads for running trains. During the operation of trains, they will be impacted by alternating loads from multiple directions. After long-term repeated rolling, the rail surface has various damages, which not only increases the operating cost of the railway, but also affects the safety of the train. [0003] At present, my country's rail transportation is developing in the direction of "high speed" and "heavy load", urban rail transit, etc. The efficiency and quality requirements of track grinding and maintenance are increasing day by day, and the maintenance workload is also increasing. Therefore, the efficiency and qualit...

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the problem in the prior art that the ordinary rail grinding method is inefficient, the surface roughness after grinding is poor, new grinding cracks and grinding burns are easy to occur, which seriously affects the service life of the rail, and the corresponding grinding The cost of equipment development is high, the structure is complex, and the maintenance of equipment is inconvenient. However, the vibration grinding technology can make the grinding wheel not easy to block, easier to threshing naturally, maintain the self-sharpening of the grinding wheel, reduce the grinding force, residual stress and grinding temperature, and avoid Or reduce grinding burns, greatly improve grinding efficiency, improve the surface quality of track processing, and prolong the life of rails. The vibration grinding rail grinding method is an effective method to solve the above problems, and a vibration grinding rail grinding method is proposed.
