Causes of overheating in piston rod machining

(1) The piston rod and the ferrule joint are tilted during installation, causing some parts to rub against each other, and adjustment should be carried out immediately;

Piston rod is a connecting component suitable for piston rod work, most of which are used in hydraulic cylinders and cylinder fitness exercise components. It is a fitness exercise component with frequent fitness exercises and high technical standards. Taking the oil pressure cylinder as an example, it is composed of several parts: cylinder liner, piston rod, piston rod, and bearing end cap.

1. Use of machinery and equipment Product workpiece standards.

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.
