The utility model discloses a pressure plate balancing device for a cutting end, relates to the technical field of cutting machine elements, and aims to solve the problems that the existing balancing structure outside the cutting end of a cutting machine only needs to be adjusted during maintenance, and the sudden inclination of a pressure plate in the use process cannot be known in time. The connecting blocks are installed on the lower side of the inner wall of the side blocking mechanism, the two connecting blocks and the lower side of the inner wall of the side blocking mechanism are integrally formed, stress induction pieces are arranged on the upper end faces of the two connecting blocks, one sides of the stress induction pieces are fixedly connected with the upper end faces of the connecting blocks, and the other sides of the stress induction pieces are fixedly connected with the lower end faces of the connecting blocks. And rotating wheels are arranged on the two sides of the inner wall of the side blocking mechanism, the two rotating wheels are rotationally connected with the side blocking mechanism through connecting rotating shafts, and the two connecting rotating shafts are arranged.

The application discloses a method for improving the contact wear resistance of a rail by refining the pearlite lamellar spacing to 260-320 nm through a staged temperature control isothermal heat treatment process combined with micro stress induction, thereby significantly improving the wear resistance and fatigue resistance while ensuring high strength. The rolling contact wear test results under a load of 20-40 N show that the Brinell hardness of the rail sample prepared by the process is increased by about 16%, the average friction coefficient is reduced by 9.8%, the wear volume is reduced by about 24.5%, and the crack initiation life is increased by about 1.4 times. The method has stable process, accurate control, is suitable for batch manufacturing of U75V heavy load and high speed rail, and has a wide industrial application prospect.
