The function and characteristics of the hydraulic piston rod

What is a piston rod? The piston rod is actually a connecting part that is usually used in cylinders, cylinders, and hydraulic cylinders to support the work of the piston. It is a widely used part in industrial machinery. It can mainly transmit torque and bear loads. effect.
Features of the piston rod:
1. Under normal circumstances, the piston rod will be designed as a cylinder. If the diameter is large, you can directly choose a hollow piston rod.
2. Normally, the piston rod is made of 45 steel. If there is a large impact force and heavy load transmission, in order to ensure that the piston rod has sufficient working strength, it should be made of 40Cr steel first.
3. After the surface layer of the piston rod is chrome-plated, it will have excellent physical properties, such as good friction resistance and corrosion resistance.
4. When manufacturing the piston rod, the blank should be forged, rough machined and then quenched and tempered. The hardness is HB=230~250. The purpose of quenching and tempering is to improve the machining performance and increase the working strength of the material.
