Torque wrench operating instructions
Mar 15, 2020
Torque wrench-also called torque wrench or torque wrench,torque is the product of force and distance.When tightening screw bolts,nuts and other threaded fasteners,you need to control the amount of torque applied to ensure that the threads are tightened and not over torque Big damage to the thread,so use a torque wrench to operate.First set an upper limit of the required torque value.When the applied torque reaches the set value,the wrench will make a "catta" sound or the joint of the wrench is bent at an angle,which means that it has been tightened and no more force is applied.
The principle that the torque wrench makes a kata sound is simple,and can be divided into the following steps to understand.
1.The torque wrench is prompted after the sound of "Kata" to reach the torque value you require.
2.The "cat" issued by the torque wrench is generated by the internal torque release structure,which is composed of a pressure spring,a torque release joint,and a torque jack.
3.First set the required torque value on the torque wrench (the spring sleeve is placed on the top rod to apply pressure to the torque release joint),lock the torque wrench and start to tighten the bolt,when the bolt reaches the torque value (when used When the torsion force is greater than the pressure of the spring),there will be an instantaneous disconnection effect.At the moment when the disjoint effect occurs,the "kata" sound emitted by the joint hitting the metal shell of the wrench is emitted.This confirms the reminder effect of reaching the torque value.(In fact,it's like the principle that our arm joints are bent at 15 degrees and placed in an iron pipe,and they will hit the steel pipe after being straightened.)
