Tips: The Working Principle of Air Impact Wrench
As the development of technology and industry, the use of air torque wrenches is becoming more common. The working principle of air impact wrench is as follows:Set the required torque value on the air torque wrench (release the joint pressure from the air impact wrench by the spring sleeve), lock the wrench and start to tighten the bolts. When the bolts reach the torque value (when the torque force is greater than the spring pressure), it will occur an instant disjointed effect. The "cata" sound produced by the joint hitting the metal shell of the wrench at the moment of the disjunction effect. This confirms the reminder to reach the torsional value. The “cata” issued by the air impact wrench is generated by its internal torsion release structure, which is composed of three structures: the pressure spring, the torsion release joint, and the torsion push rod. When the air impact wrench makes the “cata” sound, it indicates that the torque value you requested has been reached.
