Twist shear bolt torque wrench, high-strength bolt electric torque wrench

Twist shear bolt torque wrench, high-strength bolt electric torque wrench

SGNJ produced by Shanghai FoundryTwist shear bolt torque wrenchIt consists of two parts: the host and the controller. This twist shear typeBolt torque wrenchThe host adopts a dual edge single-phase series excited motor and a reduction mechanism, with a novel structure, small size, light weight, and safety. 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.

SGNJTwist shear bolt torque wrenchOperation precautions

1. The size of the bolt diameter has a certain impact on the control accuracy. During construction, the same type of bolt connection should be used to calibrate the torque value, and after a period of use, it should also be inspected and calibrated.

2. Before starting work, the machine should be turned on and idle for 3-5 minutes. If there is a large spark, abnormal sound, or unstable torque in the motor during operation, the machine should be stopped immediately for inspection. Do not work with a problem.

3. Regularly clean and replace grease. Generally, after 5000 cycles of operation, cleaning and oiling should be carried out to extend the service life.

4. The power switch, carbon brush, and fuse on the controller on the host are all vulnerable parts that can easily cause malfunctions. They should be checked regularly and replaced in a timely manner.

5. If the screws on the tool are found to be loose during use, they should be tightened in a timely manner.

6. When transporting tools, do not lift the cables and handle them gently to prevent vibration and impact. When not in use, it should be placed in a ventilated and dry place. If moisture is found, it should be dried in a timely manner. Do not come into contact with or store together with harmful substances such as acids, alkalis, etc.

SGDD type of cast balanceFixed torque electric wrenchIt is a mechanized construction tool for assembling threaded parts and bolts, with automatic torque control function. This fixed torque electric wrench is used for the installation of bolted welded structural bridges, as well as for the installation of factories, towers, and chemical, metallurgical, and power generation equipment. My torque electric wrench is also used in large-scale machinery, lifting equipment, and vehicle assembly operations, as well as in situations where there are strict requirements for the torque and axial tension of threaded fasteners.

Specification and model of fixed torque electric wrench

Selection and adjustment of torque for fixed torque electric wrench

1. Users can freely 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 coarse adjustment and coarse adjustment, in order to control the accuracy of torque. (See next page)

3. Adjustment method: Chinese products come with torque test data cards 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, and measure the actual torque value of the bolt with a force wrench or other force measuring instrument. 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 gear, and repeated several times to obtain the required torque value.

Tightening operation of bolts with fixed torque electric wrench

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.
