The piston rod is processed by rolling, which enhances the corrosion resistance of the surface and delays the generation or expansion of fatigue cracks, thereby enhancing the fatigue strength of the cylinder rod. Through rolling forming, a cold work hardening layer is formed on the rolling surface, reducing the elastic and plastic deformation of the contact surface of the grinding pair, thereby enhancing the wear resistance of the surface of the cylinder rod, while avoiding burns caused by grinding.

1. Check the integrity of the equipment, whether accessories are missing, and all tools and accessories should be placed and stored neatly.

There are two main functions, namely guidance and support. The former is to guide the upper mold and the lower mold to align in the correct position. The common problem is that there is no guide pillar guide sleeve. In addition, there can also be some support for the upper membrane column. Considering that the sliding fit between the guide pillar and the guide sleeve is relatively frequent, it is necessary to provide better lubrication performance and open a lubricating oil groove. In order to ensure the working strength of the guide pillar, the diameter of the fixed position should be about twice the diameter of its working position.

Introduce methods to enhance the corrosion resistance of the piston rod surface.

Piston rods can be used in hydraulic and pneumatic systems, and their processing requirements are relatively high. Therefore, the quality of hydraulic cylinders is mostly affected by the quality of the piston rods.
