[0002] The piston rod is a connecting component that supports the piston to do work. It is mostly used in oil cylinders and cylinder motion actuators. It is a moving component that moves frequently and has high technical requirements. Taking the hydraulic cylinder as an example, it is composed of a cylinder barrel, a piston rod, a piston, and an end cover. The quality of its processing directly affects the life and reliability of the entire product. The processing requirements for the piston rod are high, and the piston rod needs to be quenched during processing.

[0003] In the prior art, such as the quenching device for piston rod processing disclosed in patent CN202122513974.8, the quenching device for piston rod processing generally uses a clamp to place the piston rod into a quenching box. Since the temperature of the piston rod is relatively high at this time, its reaction is relatively strong when it is placed in the quenching box. Operators who are too close are easily affected and in danger. At the same time, when quenching, the piston rods are stacked together, which will cause uneven quenching and reduce the quenching quality of the piston rod. For this reason, we propose a quenching device for piston rod processing. Utility Model Content
