The socket wrench is specially used to detect the tightening torque value of the connection between the steel connecting sleeve and the steel connecting wire.
Scope of application of steel bar connection socket torque wrench: This product is suitable for testing the tightening torque value of steel bar connection with a diameter of Φ12-Φ40MM. Technical indicators of steel bar connection socket torque wrench: daily error of indication / repetition error of indication is less than or equal to 0.5%.
Specification of torque wrench for steel bar connection socket: the length of the wrench arm is 600mm. The setting range of torque value is 70~370N.M.
Operation method of torque wrench: The new wrench has been verified when it leaves the factory, has the product qualification certificate, and the torque value is set at a relatively low position.
Before use, according to the tightening torque required for the connection between the steel bar joint and 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 wrench to twist the lead screw to make the steel bar on the moving scale. The specification scale is aligned with the engraved line on the handle of the wrench, and then the jaws firmly bite the steel bar or sleeve to be connected, firmly hold the handle of the wrench, and apply force evenly clockwise. When you hear a "click" sound, you can stop adding force. At this time, the tightening torque value of the steel bar joint has reached the specified requirements.
The method for adjusting the accuracy of the wrench: insert the special key into the end hole of the tail and turn it clockwise to increase the torque value, and counterclockwise to decrease the torque value. Precautions for using torque wrench:
Note that water, mud, sand and other debris enter the handle of the wrench, and the torque wrench is strictly prohibited to be used as a hammer.
When using the wrench, the head of the wrench should be flat, and the afterburner should be uniform. Do not use excessive force or apply impact force.
When you hear a "click" sound from the torque wrench, stop pulling the wrench immediately to avoid damage to the force measuring part of the wrench.
It is strictly forbidden to use the wrench when the set position is zero, because in this state, no sound signal is sent after afterburning, and it is easy to overload and damage the wrench.
When the wrench is not used for a long time, the scale value of the wrench should be set at the zero position to avoid fatigue and misalignment of the force measuring element.
During use, if the wrench has no sound signal, stop using it immediately and carry out maintenance. The repaired wrench needs to be calibrated and can be used only after the calibration is qualified.
