The reason why the industrial grade pneumatic torque wrench makes a catch-sound.

Industrial grade pneumatic torque wrench is also known as torque meter, torque screw driver. It is designed according to the bending principle of the beam, the bending principle of the torsion bar and the compression principle of the helical spring, and can measure the torque acting on the nut. The torque wrench has a long elastic rod, one end is equipped with a handle, the other end is equipped with a square or hexagonal head, the square or hexagonal head is set with a replaceable sleeve, and the steel ball is stuck. There is also a long pointer at the top. The scale plate is fixed on the handle seat, and the scale value of each cell is 1N (or kg/m). Before use, first adjust the indicator installed on the wrench to the required torque, and then turn the wrench, when the predetermined torque is reached, the pointer on the indicator will turn to the pin side, the pointer and the pin collision, through the sound box signal or sensing signal to inform the operator.
The correct use of industrial grade pneumatic torque wrench:
(1) The user can not arbitrarily remove the parts of the wrench and operate, in addition to affecting the safety of the operator will also cause damage to the wrench.
(2) If the wrench is slightly faulty or cannot reach the original function after use, it can no longer be used, and it should be checked immediately.
(3) Be sure to follow all safety regulations and instructions.
(4) To choose the appropriate wrench to work, the torque range is too large or too small will affect the assembly quality.
The principle of the sound produced by the industrial pneumatic torque wrench is very simple, and can be divided into the following steps to understand:
1, the torque wrench in the "kata" sound is to indicate that you have reached the required torque value;
2, the torque wrench issued by the "tower" is generated by its own internal torque release structure, its structure is divided into pressure spring, torque release joint, torque rod three structures.
3. First set the required torque value on the torque wrench (the spring is set on the top rod to release the pressure on the torque joint), lock the torque wrench, and start tightening the bolts. When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), it will produce an instant disconnection effect. The "katta" sound produced by the metal shell of the wrench is produced at the moment of the disconnection effect. This is to confirm the reminder effect of reaching the torque value (in fact, it is just like the principle that our arm joints are bent at 15 degrees and will touch the steel pipe after being stretched straight in the iron pipe for a moment).
