Introduction to processing and heat treatment of hydraulic cylinder piston rod

Feb 10, 2024

Hydraulic cylinder is an important actuator in the hydraulic system of engineering machinery. It is used to perform reciprocating motion and drive engineering machinery to complete various functions.
The piston rod is a key force transmission part with high technical requirements for connecting the piston and the working parts in the hydraulic cylinder. It needs to withstand large tensile stress during the working process. Therefore, the piston rod must have sufficient strength, stiffness, and toughness. At the same time, due to the It is easily abraded by abrasive particles and must have high wear resistance.
The long cylinder piston rod is made of 45 steel, and its processing route is: forged material (rolled material) - blanking - quenching and tempering - straightening - mechanical processing - surface quenching, tempering - straightening - rod head welding - machining - Grinding - stress relief annealing - polishing - hard chromium plating - polishing - cleaning - assembly.
When processing high-quality hydraulic cylinders, look for feed machinery and professional quality assurance. The heat treatment of the piston rod is a key process to ensure the intrinsic quality and mechanical properties of the piston rod. The quality of the heat treatment is directly related to the life and reliability of the entire hydraulic system. If the heat treatment is improper , causing the piston rod to break early during use, which may cause damage to other parts in mild cases, and may cause damage to the entire equipment and casualties in severe cases.
