The piston rod of the oil cylinder is a connecting component used to support the piston rod to do work. It will repeatedly perform events under some conditions such as low temperature, high speed, dry defense, and corrosion. Therefore, in order to allow the piston rod to be able to perform different changes in different conditions or under the condition of insufficient safety, so that the piston rod may have ample strength and surface hardness, and anti-erosion, anti-conflict, anti-shrinking, and anti-seizure methods must be correct. Piston rods are subject to related workmanship treatment and punishment, which is analogous to the workmanship of rolling and high-frequency quenching. The following editor will share with me the high-frequency quenching skills of cylinder piston rod processing:
High-frequency quenching is a metal heat treatment method that generates a certain sense current on the surface of the piston rod, then quickly heats the surface of the whole machine, and then quenches it quickly at the end.
the goal:
The surface of the piston rod suffers from the martensite structure in the bound depth range, while the core part still maintains the microstructure before surface quenching (tempered or normalized condition) to obtain a hard and wear-resistant surface layer. It has abundant shaping and toughness.
