Punch air spring is an elastic element used in punching machines (such as mechanical punches, hydraulic punches, etc.), which uses the characteristics of compressed air to achieve functions such as buffering, shock absorption, support or force balance.
1. Core functions
Buffering and shock absorption: absorb the impact force and vibration generated during the punching process to protect the mold and equipment structure.
Force balance: balance the weight of the slider or mold and reduce the load of the drive mechanism.
Height/pressure adjustment: change the stiffness and support height of the spring by adjusting the air pressure to adapt to different working conditions.
2. Working principle
By filling the airbag with compressed air, the compressibility of the gas is used to provide elastic force. When the punch slider is pressed down, the air spring is compressed and absorbs energy; when returning, the stored energy is released to assist in resetting. The greater the air pressure, the higher the spring stiffness.
3. Application scenarios
Mechanical punch: balance the weight of the slider and reduce the motor load.
Precision stamping: reduce vibration and improve the forming accuracy of the workpiece.
Continuous stamping production line: stabilize the feeding mechanism to avoid material deviation.
Mold protection: Prevent mold damage caused by overload.
