Precision piston rod is a connecting component that supports the piston to perform work, and is mostly used in oil cylinders and cylinder motion execution components. It is a moving component with frequent movement and high technical requirements. Taking hydraulic oil cylinder as an example, it consists of several parts: cylinder barrel, piston rod (cylinder rod), piston, and end cover.
1. The purpose of this product is the workpiece conditions.
2. The structural characteristics, load situation, required speed, size and stroke, and action requirements of the working mechanism.
3. The working pressure of the selected hydraulic system.
4. The current status of materials, accessories, and processing technology.
5. Precision piston rods should comply with relevant standards and technical specifications.
6. We should try our best to make the product withstand a large load in a multi tension state and have good longitudinal stability in a multi pressure state.
The above are the design considerations for precision piston rods.
