　　Adjustable torque electric wrench

　　Introduction of adjustable torque electric wrench

　　This adjustable torque electric wrench is suitable for tightening and loosening bolts, nuts and tightening bolts. Adjustable torque electric wrenches should be used in the erection of bolt-welded structural bridges, the installation of workshops, towers, and chemical and power generation equipment.

　　Features of adjustable torque electric wrench:

　　The adjustable torque electric wrench is composed of two parts: the main engine and the control instrument. The main engine adopts a dual, single-phase series motor and a deceleration mechanism. It has a novel structure, small size, and light weight. Due to the static torsion structure, the operation is stable, there is no vibration, no impact, and low noise. The operator is not affected by the reverse moment, so the labor intensity is low. Rated voltage 220V50/60Hz, accuracy ±5%.

　　Selection and Adjustment of Torque of Adjustable Torque Electric Wrench

　　1. The user can arbitrarily choose the corresponding specifications within the range of 50-3500N.m

　　Fixed torque electric wrench.

　　2. There is a "torque adjustment knob" on the control panel. Engraved with 0-10 scale values. The function of the fine adjustment knob is to adjust and compensate between the two coarse adjustments, and to control the accuracy with torque. (See next page)

　　3. Adjustment method: The domestic product comes with a torque test data card when it leaves the factory for the user to refer to when calibrating. The user can select a certain scale value according to the required torque. According to the operation method of tightening the bolt, tighten the bolt, use a force measuring wrench or other The force measuring instrument measures the actual torque value of the bolt. If the torque difference is small, fine adjustment can be used to compensate. If the difference is large, the coarse adjustment can be adjusted up or down by one gear, and the required torque value can be obtained by repeating several times.

　　Tightening operation of bolts of adjustable torque electric wrench

　　1. Install the anti-bracket and tighten the screws. Start the main engine, make the square head pin hole correspond to the anti-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 and negative switch of the host to the forward position, and put the wrench sleeve on the six sides of the threaded connection.

　　3. Press the power switch to start the wrench. When the anti-support arm is firmly against the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum) the bolts begin to tighten. When the bolt torque reaches the predetermined torque, the wrench automatically stops, the tightening is completed, the power switch is released, and the next bolt is tightened.

　　4. After the wrench stops automatically, rely on the elastic deformation of the bracket to automatically disengage the bracket arm from the fulcrum, and then remove the wrench. If the arm cannot be separated from the fulcrum, you can flip the positive and negative switch, and then the power switch wrench can be removed.
