High precision electric torque wrench with a torque range of 200-700N. m

※Usage and characteristics:

　　High precision electric torque wrench with a torque range of 200-700N. m‍The upgraded product is a mechanized construction tool for assembling threaded parts and bolts, with automatic torque control function. Widely used in the installation of bolted and welded structure bridges, as well as in the installation of factories, towers, chemical, metallurgical, and power generation equipment. Large machinery, lifting equipment, and vehicle assembly operations, as well as situations with strict requirements for torque and axial tension of threaded fasteners.

This series of products is formed by integrating the host and controller. The host adopts a dual insulated single-phase series excited motor and reduction mechanism, with a novel structure, small size, light weight, and safe and reliable performance. Due to the use of a static torsion structure, the operation is smooth, without vibration or impact, with low noise, and the operator is not affected by the reaction torque, resulting in low labor intensity.

Electric digital torque wrench※Instructions for use

　　oneConnection of power supply

First, connect the power cord of the host to the power grid.

　　twoTightening operation of bolts

1. Install the reaction bracket and tighten the screws. Start the host, align the square pin hole with the reaction bracket hole, then install the wrench socket, insert the pin, and fix it with a rubber ring.

2. Adjust the torque knob of the controller to the desired torque value, turn the positive and negative switches of the host to the positive rotation position, and insert the wrench socket onto the hexagonal threaded connector.

3. Press the power switch to activate the wrench. When the force arm of the reaction bracket is firmly attached to the bracket (the fulcrum can be an adjacent bolt or other position that can serve as a fulcrum), the bolt begins 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 tightening work is carried out.

4. After the wrench stops automatically, the elastic deformation force of the reaction bracket causes the bracket arm to automatically detach from the fulcrum and remove the wrench. If the lever arm cannot detach from the pivot point, the forward and reverse switches can be turned, and the power switch wrench can be used to remove it.

3、 Dismantling operation of bolts

When dismantling bolts (reversing) with a wrench, the operation method is the same as tightening, except that the forward and reverse switches are turned to the reverse position, the bolts are loosened, and the power switch is released.

　　4、 Selection and adjustment of torque

1. Users can access 200-50Choose any electric wrench of the corresponding specification within the range of 00Nm.

2. There is a "torque adjustment knob" on the control panel. The function of the fine adjustment knob is to adjust and compensate between the coarse adjustment and coarse adjustment levels, in order to improve the accuracy of torque control.

3. Adjustment method: The product comes with a torque test data card at the factory for users to refer to during calibration. Users can select a certain scale value based on the required torque, tighten the bolt according to the operation method of tightening the bolt, and use a force wrench or other force measuring instrument to measure 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, coarse adjustment can be adjusted up or down by one level, and repeated several times to obtain the required torque value.
