What is a Punch Air Spring

1. Basic functions
Buffering and shock absorption: When the punch press works at high speed, it absorbs the impact force when the slider and the mold come into contact, reducing vibration and noise.

Pressure control: By adjusting the air pressure, it provides stable pressure output to meet the needs of different stamping processes (such as punching, stretching, etc.).

Protect the mold: Reduce the damage to the mold caused by impact and extend the life of the mold.

Precise control: Cooperate with the CNC system to achieve precise adjustment of stroke and pressure to improve processing quality.

2. Structure and working principle
Structure: It is mainly composed of cylinder, piston, seal, air pressure regulating valve, etc., and is filled with compressed air.

Working principle:

Compression stage: When the punch press slider moves downward, the air spring is compressed, the air pressure increases, and energy is stored.

Release stage: When the slider returns, the compressed air expands, pushing the piston to reset, assisting the slider to return quickly and buffering vibration.

3. Core advantages
Adjustability: The elastic force can be changed by adjusting the air pressure to meet the needs of different materials and processes.

Fast response: more sensitive than mechanical springs or hydraulic systems, suitable for high-speed stamping.

Easy maintenance: no complex mechanical structure, low failure rate, can be repaired by replacing seals.

Energy saving and environmental protection: compared with hydraulic systems, no oil is required to avoid pollution and energy consumption.

4. Application scenarios
Stamping industry: used for precision stamping of automotive sheet metal, electrical housing, hardware, etc.

Continuous punching: ensure stability in high-speed punching machines (such as progressive die stamping).

Stretch forming: provide uniform blanking force to prevent material wrinkling.

5. Selection points
Load requirements: select the load capacity of the air spring according to the punching force.

Stroke length: match the movement stroke of the punch slide.

Air pressure range: ensure that the air source pressure is compatible with the rated pressure of the spring.

Installation size: needs to be compatible with the punch structure.
