Chrome hardened bars in the work and production requirements according to different situations need to go through different processing techniques, quenching and plating and plating methods are two very important ways in the production of piston rods.
Their purpose is actually very simple. It is to use the piston rod as much as possible to avoid frequent problems due to conventional use problems. Such as wear, cracks and so on.
Tempering and tempering can help to close the cracks on the surface of the piston rod and improve the corrosion resistance. Simply plating can improve surface wear resistance and the piston rod slows down wear during use.
There is also a surface nitriding treatment to increase the hardness of the piston rod at one time, which is often used in combination with the single-column hydraulic press to achieve the overall hardness of the surface. The hardness and surface condition are improved by quenching and tempering, and the wear resistance of the surface is improved by plating to have excellent performance of the piston rod.
And its processing technology can improve the surface corrosion resistance, and can delay the generation or expansion of fatigue cracks, thus improving the fatigue strength of the cylinder rod. By rolling forming, the rolling surface forms a cold hardening layer, which reduces the elastic and plastic deformation of the grinding contact surface, thereby improving the wear resistance of the cylinder rod surface and avoiding burns caused by grinding. After rolling, the surface roughness value is reduced to improve the compounding property. At the same time, the friction damage to the sealing ring or the sealing member during the movement of the cylinder rod piston is reduced, and the overall service life of the oil cylinder is improved. The rolling process is an efficient and high quality process.
