In the recent visit statistics of the website of our company, users are looking for instructions on the use of electric torque wrenches . For this reason, Xiao Bian has collated the instructions of the electric torque wrench for the user. The electric torque wrench is a mechanized construction tool for assembling screw parts and bolts. It has the function of automatic control of torque and is widely used in the erection of bridges with bolted structures. The installation of power plants, towers, and chemical, metallurgical and power generation equipment and large machinery and lifting equipment. And vehicle assembly operations and places where stringent torque and axial tension on threaded fasteners are critical.
Electric torque wrench instructions
Tighten the electric torque wrench bolts.
1. Install a counter force bracket and tighten the screws. Turn on the main unit so that the square pin hole corresponds to the reaction bracket hole, then install the wrench sleeve, insert the pin, and fix it with the rubber ring.
2. Adjust the torque knob of the controller to the required torque value, turn the positive/negative switch of the main unit to the forward rotation position, and put the wrench sleeve on the six sides of the threaded connection.
3, press the power switch, wrench start. When the force arm of the reaction force stand is placed on the stand (the fulcrum can be a nearby bolt or other fulcrum), the bolt is tightened. When the torque of the bolt reaches the predetermined torque, the wrench is automatically stopped and the tightening is completed. The power switch is released and the next bolt is tightened.
4. After the wrench is automatically stopped, rely on the elastic deformation force of the reaction force support to automatically disengage the force arm of the support from the fulcrum and remove the wrench. If the arm can not be separated from the fulcrum, you can toggle the positive and negative switch, click the power switch wrench can be removed.
Electric torque wrench precautions operation
1. Before connecting the power supply, check whether the power supply voltage matches the nameplate of the product. Is there a grounding device? When the power supply voltage exceeds +10%, the voltage regulator should be used, otherwise it will affect the control accuracy. Poor grounding can cause accidents.
2. The ambient temperature of the tool is -10°C-40°C. If the temperature is too high or too low, it will affect the control accuracy.
3. The initial torque of the screwed bolt shall not be greater than 70% of the rated torque of the tool. Do not re-tighten bolts after reaching the rated torque.
4. When the tool is used to remove the bolt, its torque must not exceed the rated torque value. Under normal circumstances, this wrench is not a bolt that is tightened or has severe corrosion. Do not remove it with this wrench to avoid damage to the tool.
5. When changing the rotation direction, it must be done after the motor stops rotating. It is forbidden to toggle the positive and negative switches during operation. 6. When the wrench is automatically stopped, the switch can be released (if the switch is not turned off, the wrench will start automatically after 5 seconds) Wait 4-5 seconds before starting the wrench, or the wrench will not start.
