Basic requirements and roll forming of piston rod
Jun 23, 2022
The piston rod is rolled and formed, and its rolled surface will form a cold-work hardened layer, which can reduce the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the surface of the cylinder rod, and avoiding the wear and tear of the cylinder rod. burns caused by cutting.
After the piston rod is rolled, its surface roughness value is reduced, which can effectively improve the matching properties, and at the same time, reduce the friction damage to the seal ring or seal when the cylinder rod and piston move, and improve the overall service life of the cylinder. The rolling process is an efficient and high-quality process method.
Basic requirements for piston rods
1. The piston rod requires sufficient strength, stiffness and stability to a certain extent.
2. The piston rod has good wear resistance and requires high machining accuracy and surface roughness.
3. Minimize the influence of stress concentration on the structure.
4. Make sure the connection is firm and avoid loosening.
5. The design of the piston rod structure should facilitate the disassembly and assembly of the piston.
