Principle of Pneumatic Impact Wrench

Pneumatic impact wrench is a tool that uses the high-speed rotational force generated by compressed air to apply impact force to tighten or loosen screws and bolts. Its working principle is as follows:

Compressed air enters the cylinder of the pneumatic wrench and pushes the piston to move.

The piston moves quickly in the cylinder and transfers energy to the wrench head connected to the piston.

When the wrench head contacts the workpiece, it generates rotation and impact force.

This rotation and impact force can help quickly tighten or loosen screws and bolts.

The pneumatic impact wrench achieves efficient tightening and loosening of screws and bolts by converting the kinetic energy of compressed air into force.
