Hydraulic Cylinder Description

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

Shock Absorber

The hydraulic cylinder is used in the hydraulic system to drive the mechanism with a certain mass. When the hydraulic cylinder moves to the end of the stroke, it has a large kinetic energy. If it is not decelerated, the hydraulic cylinder piston and the cylinder head will have a mechanical collision, resulting in impact, noise and destructive. In order to mitigate and prevent this hazard, a decelerating device can be set up in the hydraulic circuit or a buffer device can be set up in the cylinder block.

Cylinder Processing

As the main parts of hydraulic cylinder, single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel.

Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved. 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, thereby 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 value can improve the matching property.
