Electric torque wrenchIntroduction:

The SGDD series produced by the foundry manufacturerElectric torque wrenchIt is a mechanized construction tool for assembling threaded parts and bolts, with automatic torque control function. This model200-700 NmElectric torque wrenchSuitable for the installation of bolted welded structure bridges, as well as 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.Electric torque wrenchIt consists of two parts: the host and the controller. The host adopts a dual insulated single-phase series excited motor and a reduction mechanism, with a novel structure, small size, light weight, and no harm. 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. rated voltage220V50/60Hzprecision±5%.

Electric torque wrenchIt consists of two parts: the host and the controller. The host adopts a dual insulated single-phase series excited motor and a reduction mechanism, with a novel structure, small size, light weight, and no harm. 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. rated voltage220V50/60Hzprecision±5%.

Electric torque wrenchTightening 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.

Electric torque wrenchSelection and adjustment of torque

1. Users can50-3500N. mChoose any corresponding specification within the scopeElectric torque wrench.

2. There is a "torque adjustment knob" on the control panel. engraved with0-10A scale value. 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. (See next page)

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.

Electric torque wrenchPrecautions for operation

(Special attention should be paid)

1. Before connecting the power supply, check whether the power supply voltage matches the nameplate of this product and whether there is a grounding device. When the power supply voltage exceeds+10%Voltage stabilization measures should be taken at this time, otherwise it will affect the control accuracy. Poor grounding can easily cause accidents.

2. The ambient temperature for tool use is-10℃-40Both high and low temperatures can affect control accuracy.

3. The initial torque of the tightened bolt shall not exceed the rated torque of the tool70%After the bolt reaches the rated torque, it shall not be re tightened.

4. When the tool is used to disassemble bolts, its torque must not exceed the rated torque value. Generally, bolts that are not tightened with this wrench or severely corroded should not be disassembled with this wrench to avoid tool damage.

5. When changing the direction of rotation, it must be done after the motor has stopped rotating, and it is strictly prohibited to toggle the positive and negative switches during operation.

6. After the wrench stops automatically, the switch can be released (if the switch is not turned on5The wrench will start automatically in seconds4-5Wait for seconds before starting the wrench, otherwise the wrench cannot be started.
