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

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.

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

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

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

3. After quenching and tempering treatment, the internal stress caused by straightening should be ensured not to hinder the subsequent processing, manufacturing, and application of the piston rod. If necessary, stress relief should be carried out.
