The piston rod is an important part of the gas-liquid pressurized cylinder equipment, and it will directly affect the use of the entire equipment. The processing quality of the piston rod will have a very important impact on the stability of the hydraulic pneumatic cylinder.
The process requirements of the piston rod are as follows:
1. Selection of materials and quenching and tempering treatment: to ensure the toughness of the piston rod and its wear resistance;
2. Machining precision: separate rough turning and fine turning, rough grinding and fine grinding, use center frame and follower tool post;
3. Coaxiality tolerance and equal position accuracy accuracy: the positioning of the two central holes conforms to the unified standard;
4. Stability of processing accuracy: manual straightening is not allowed.
