Hydraulic Cylinder Barrel

Due to the residual compressive stress in the surface layer, the rolling machining is conducive to the sealing of micro-cracks and the propagation of erosion is hindered. Thus, the surface corrosion resistance can be improved, and the fatigue crack generation or expansion can be delayed, so as to improve the cylinder fatigue strength. 

Hydraulic Cylinder Barrel processing method

Due to the residual compressive stress in the surface layer, the rolling machining is conducive to the sealing of micro-cracks and the propagation of erosion is hindered. Thus, the surface corrosion resistance can be improved, and the fatigue crack generation or expansion can be delayed, so as to improve the cylinder fatigue strength. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the inner wall of the cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness can improve the fit property.

Hydraulic Cylinder Barrel description

Hydraulic cylinder is the executive component of hydraulic transmission system, it is the energy conversion of hydraulic energy into mechanical energy. The hydraulic motor is to achieve continuous rotary motion, and the hydraulic cylinder is to achieve reciprocating motion. Hydraulic cylinder structure type has piston cylinder, plunger cylinder, swing cylinder three categories, piston cylinder and plunger cylinder reciprocating linear motion, output speed and thrust, swing cylinder reciprocating swing, output angular speed (speed) and torque. In addition to the single use of hydraulic cylinders, but also two or more combined or combined with other mechanisms used. To fulfill a particular function. Hydraulic cylinder is simple in structure and reliable in operation. It has been widely used in hydraulic system of machine tools.
