Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber production and processing, in particular to special shock absorber production equipment. Background Art

[0002] Shock absorbers are used to reduce the impact of the reaction force of the spring after absorbing the vibration on the vehicle. It slows down and disperses the vibration energy through the elastic deformation of the internal damping material, thereby improving the comfort and handling stability of the vehicle. The outer shell of the shock absorber is usually formed by shrinking and grooving the pipe. This processing method can ensure that the shock absorber shell has sufficient strength and rigidity to withstand the rebound force of the spring and the impact from the road. In addition, the shrinking and grooving processing can also make the shock absorber more compact, convenient for installation and use.
