Hydraulic cylinder is a kind of pressure actuator which can transform hydraulic pressure into mechanical energy and do linear reciprocating motion. Its structure is simple and its work is reliable. When it is used to realize reciprocating motion, there is no reduction device, and there is no transmission clearance, so it is widely used in various mechanical hydraulic systems.
Advantages of hydraulic cylinder:
1. According to the processing nature, it can be divided into intensive processing and finish processing.
2. According to the processing method of external force transfer to rolling tool, it can be divided into three types: rolling type, mechanization and spring type.
3. The surface roughness can be increased from ra6.3 to ra2.4-ra0.2 by rolling. And has high production efficiency, some workpieces can be completed in a few seconds.
4. Rolling processing can solve some key problems that cannot be realized by some technological methods.
5. After the surface rolling of the metal workpiece, the ultimate strength and yield point of the surface layer are increased, and the service performance, wear resistance, fatigue strength and corrosion resistance of the workpiece are significantly improved. After the rolling, the hardness can be increased by 15-30%, and the wear resistance is increased by 15%.
6. Rolling is widely used in various large, medium and small factories. No matter from the aspects of processing quality, production cost and production efficiency, rolling is a better processing method. In some aspects, it can completely replace grinding, fine grinding and other finishing.
