We are no stranger to the torque wrench. It is a tool for detecting the tightening torque value of the connecting rod of the reinforcing steel and the connecting wire of the steel bar. For users who do not understand the use of the torque wrench and the matters needing attention, they must come here. If you don't understand the use of torque wrenches and precautions, then using torque wrenches is very easy to fail.
Today, we will introduce the Shanghai torque wrench Xiaobian, “How to use torque wrenches and precautionsâ€.
Torque Wrench Profile
Torque wrench range of application: This product is suitable for the test of the tightening torque value of the steel bar connection with a diameter of Φ12-Φ40MM.
Torque Wrench technical indicators: The daily error/indicator repeat error is less than or equal to 0.5%.
Torque wrench specifications: wrench arm length 600mm. Torque value setting range 70~370N.M.
How to Use the Torque Wrench: The new torque wrench has passed the inspection at the factory and has product certification. The torque value is set at the lowest position. Before use, according to the tightening torque required to connect the steel bar joint with the steel bar connecting sleeve, set the scale value of the moving scale on the wrench to the corresponding position, that is, use a special torque wrench to twist the screw to make it on the swimming scale. The steel bar calibration mark is aligned on the handle of the wrench and then the jaws are clamped on the steel bar or the sleeve. Hold the handle of the wrench firmly and increase the force clockwise. When you hear a “click†sound, you can stop it. After the force is applied, the tightening torque of the steel joint has reached the specified requirement.
Adjust the accuracy of the torque wrench: insert the special key into the face of the tail end clockwise to increase the torque value, and counterclockwise to reduce the torque value.
Using a torque wrench Note:
1. Pay attention to waterproof, mud, sand and other debris into the handle of the wrench, torque wrench is strictly prohibited when using the hammer.
2. When using the torque wrench, the clamp head should be flat and the force should be uniform. Do not use excessive force or impact force.
3. When you hear the sound of the torque wrench issuing a "click", immediately stop pulling the torque wrench to avoid damage to the force measuring part of the torque wrench.
4. When the torque wrench is not suitable for a long time, the scale value of the torque wrench should be set at the zero position so as to avoid fatigue misalignment of the original force measuring element.
5. The torque wrench is strictly prohibited to be used when the set position is zero, because in this state, the booster silent sound signal is issued, and it is easy to overload and damage the torque wrench.
6. In use, if the torque wrench does not emit a signal, it should be immediately stopped for maintenance. After the maintenance of the wrench needs calibration, calibration can be used only.
