How are Air Springs Used in Stamping Machines?
The application of air springs in stamping machines is mainly for shock absorption, vibration isolation, load balancing and improving stamping accuracy, especially in high-speed stamping or precision stamping processes.

Vibration problems in stamping machines
When stamping at high speed (such as hundreds of strokes per minute), the stamping machine will produce strong mechanical vibration and impact, resulting in:

• Loosening of equipment foundation, affecting stability.
• Shortening of mold life (vibration aggravates wear).
• Degradation of product accuracy (vibration causes positioning deviation).
• Noise pollution (vibration is transmitted to the ground or surrounding equipment).

Vibration isolation of stamping machine base
Installation location: between the stamping machine and the foundation (replacing traditional rubber pads or steel springs).

Function:
Absorb vertical impact force during stamping and reduce vibration transmitted to the ground (vibration isolation efficiency can reach more than 90%).
Adapt to load changes of stamping machines of different tonnages by adjusting air pressure.

Advantages:
Lower natural frequency than metal springs, suitable for high-frequency impact isolation.
No plastic deformation after long-term use (rubber pads are prone to aging and collapse).
