What if the piston rod breaks during machining

The piston rod is processed by rolling, so as to enhance the corrosion resistance of the surface and delay the generation or expansion of fatigue cracks, so as to enhance the fatigue strength of the oil cylinder rod. Through rolling forming, a cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, so as to enhance the wear resistance of the cylinder rod surface and avoid the burn caused by grinding.

After rolling, the reduction of surface roughness can enhance its matching properties. At the same time, the friction damage to the seal ring or seal during the movement of the oil cylinder rod piston is reduced, and the overall service life of the oil cylinder is prolonged. Rolling process is a process measure with high efficiency and quality.

How to deal with the fracture of piston rod during machining?

1. Adjust the moving speed between the product and the induction switch to avoid the occurrence of heat treatment soft belt.

2. Appropriately expand the output power of electromagnetic induction heating, so that the surface strength and reasonable hard bottom layer deeply consider the commodity requirements.

3. After the quenching and tempering treatment, the internal stress of the product workpiece to be straightened shall not hinder the subsequent processing, manufacturing and application of the piston rod, and the in-situ stress solution shall be carried out when necessary.
