After the piston rod is formed by rolling, its rolling surface will form a layer of cold work hardening, which can reduce the elastic and plastic deformation of the grinding pair contacting the surface, and then improve the wear resistance of the cylinder rod surface, and at the same time avoid the occurrence of wear. Burns caused by shaving.
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 piston moves, and improve the overall service life of the cylinder. The rolling process is an efficient and high-quality process method.
The basic requirements of the piston rod
1. The piston rod requires sufficient strength, rigidity and stability to a certain extent.
2. The piston rod has good wear resistance and has higher processing accuracy and surface roughness requirements.
3. Minimize the influence of stress concentration on the structure.
4. Ensure that the connection is firm and avoid loosening.
5. The design of the piston rod structure should facilitate the disassembly and assembly of the piston.
