Core Functions and Roles: F-120-3 Rubber Air Spring

When a punch press is in operation, the slide (upper die) impacts downward at extremely high speeds, completing processes such as stamping, stretching, and bending. Air springs play a crucial role in this process, primarily in the following areas:

Balance and Support (The Most Important Function):

The slide and upper die of a punch press are extremely heavy. Without a balancing device, the slide would accelerate due to its own weight during downward movement, causing significant shock and vibration. The upward movement would require the motor to expend enormous energy.

The upward force of the air spring perfectly balances the weight of the slide and die. This results in:

• Smooth Operation: The slide moves more smoothly, reducing shock and vibration.
• Equipment Protection: Wear on related transmission components such as the screw, gears, and clutch is significantly reduced, extending equipment life.
• Energy Savings: When moving upward, the motor only needs to provide enough force to overcome the pressure of the air spring, rather than lifting the entire weight, resulting in significant energy savings.
• Preventing the Slide from Falling: In the event of an unexpected power outage or malfunction, the supporting force of the air spring prevents the slide from suddenly falling due to its own weight, providing safety protection.

Cushioning and Shock Absorption:

At the moment of the punch stroke ending, air springs absorb and cushion the enormous impact energy, much like shock absorbers in a car, protecting the press body and die from damage while also reducing noise.

Providing a Pressure Source (Serving as an Air Cushion):

During the drawing process, the die typically requires a "blank holder" to hold the sheet edge down and prevent wrinkling. Air springs act as a cushion, providing adjustable, stable pressure to the blank holder, which is crucial for achieving high-quality drawn parts.

Punch press air springs are an essential component of modern stamping equipment. Like an "air spring," they use the force generated by compressed air to balance the weight of the punch press's moving parts, reduce shock and vibration, protect the equipment, save energy, and can serve as a pressure source for certain processes. They are key to the efficient, smooth, and safe operation of punch presses.
