[0002] Hydraulic cylinder is a kind of pressure finishing process, which uses the cold plasticity of metal at room temperature and uses rolling tools to apply a certain pressure on the workpiece surface, so that the surface metal of the workpiece produces plastic flow and fills into the original residual concave trough, thereby reducing the surface roughness of the workpiece. Due to the plastic deformation of the rolled surface metal, the surface organization is cold hardened and the grains are refined, forming a dense fiber shape, and a residual stress layer is formed, the hardness and strength are improved, thereby improving the wear resistance, corrosion resistance and compatibility of the workpiece surface.

[0003] The prior art discloses a polishing device for oil cylinder processing with the publication number of CN211760269U, which includes a workbench, a hydraulic cylinder and a polishing motor, the surface of the support plate is provided with a lubricating liquid sponge; the polishing motor is fixedly mounted on the top of the support frame, the output end of the polishing motor is fixedly mounted with a polishing plate through a telescopic bracket corresponding to the top of the support plate, and the support frame is fixedly mounted with an exhaust plate through an exhaust fan corresponding to the side of the polishing plate; the support frame is respectively provided with a rotating motor and a hydraulic rod on the opposite sides of the support plate, the output end of the rotating motor is provided with a resistance plate, and the end of the hydraulic rod is provided with a resistance plate 2 corresponding to the resistance plate. The polishing device for oil cylinder processing greatly improves the efficiency of oil cylinder polishing, reduces the workload of workers for oil cylinder polishing, and improves the effect of oil cylinder polishing by applying lubricating liquid to the polishing position while polishing the oil cylinder.

[0004] The above-mentioned surface polishing device for hydraulic cylinder processing improves the polishing effect of the cylinder by applying lubricating liquid to the polishing position while grinding and polishing the cylinder.
