High frequency induction heating equipment applied to piston rod quenching and tempering production line

Piston rod is an important part of motion executive components such as cylinders and oil cylinders. It is mainly connected to pistons for frequent movements, and its technical requirements are very high. When working, the piston rod is required not only to have sufficient strength, toughness and stability, but also to have good wear resistance and high precision, so its processing quality directly affects the life and reliability of the entire machine. The long-term working environment and strength cause the surface of the piston rod to corrode, the friction is severe and even break, and the service time is short. After many experiments, it has been shown that in addition to selecting 45 steel with better performance as a material, quenching and tempering treatment (piston rod quenching and tempering production line) is required to further stimulate its internal structure advantages and improve the surface corrosion resistance of the piston rod. Delay the occurrence or expansion of fatigue cracks and enhance its fatigue resistance.

The piston rod quenching and tempering production line is professionally developed and produced by Zhengzhou Gou's. Its main components are composed of: high-frequency induction heating equipment, induction heating system, quenching, tempering and other induction heat treatment systems. The whole set of equipment adopts intelligent control, real-time monitoring of the entire quenching and tempering state through the power supply, remote control operation, no need for many people, greatly saving labor. The internal programming system can set suitable process parameters according to the length and shape of the workpiece to be heated. The equipment also has a fault self-diagnosis function. During the heating process, if problems such as overwater and overpressure occur, it can judge by itself and activate the protection device to avoid the paralysis of the entire production line. Each step is a modular layout of independent units, the structure is optimized very well, and the maintenance rate is reduced.

The high-frequency induction heating equipment of the power supply adopts the imported IGBT protection technology, and the DSP digital control components improve the reliability and stability of the equipment. The power factor is high, and there will be no loud noise and unpleasant gas during tempering, which can save energy and protect the environment to a large extent.
