In the hydraulic system, a hydraulic cylinder is used to drive a mechanism with a certain quality. When the hydraulic cylinder moves to the end of the stroke, it has a large kinetic energy. If it is not decelerated, the piston of the hydraulic cylinder and the cylinder head will mechanically collide, causing impact and noise. Destructive. In order to alleviate and prevent this hazard, a deceleration device can be installed in the hydraulic circuit or a buffer device in the cylinder. Rolling processing has a wide range of applications, and can be used in all large, medium and small factories; after the surface of the metal workpiece is rolled, the surface is strengthened, the ultimate strength and yield point are increased, and the use performance, fatigue strength, and wear resistance of the workpiece Both performance and corrosion resistance have been significantly improved.
