Technological Reform and Practice of Rail Weld Grinding Equipment
The quality of seamless rail welding joints directly affects the safety of high-speed train operation.At present,the sudden change point between the welding joint reinforcement and the base metal in the welding process of long steel rails cannot be smoothly transitioned through mechanized means,and the welding reinforcement wave cannot be completely eliminated.Only manual assisted grinding can be used for processing,which not only leads to unstable processing quality,but also goes against the requirements of accelerating the realization of railway equipment intelligence in the"Transportation Power"strategy.Based on this,research is carried out on the structural characteristics of the full section of the welded joint after rail welding,comprehensively applying robot intelligent vision,intelligent force control technology,and human like operation technology.An innovative set of automatic polishing equipment for the full section of the rail welded joint robot is developed to achieve automatic grinding of the full section welded bars,solving the problems of stress concentration and welding bar waves caused by sudden changes in the appearance size of the welded joint section.
