Tightening operation of twisting and shearing bolts for special wrenches of torsional shear type
Tightening operation of twisting and shearing bolts for special wrenches of torsional shear type
1. Twist the bolt to install the reaction support and tighten the screws. Start the main engine, make the square head pin hole correspond to the counterforce bracket hole, then install the wrench sleeve, insert the pin and fix it with rubber ring.
2, the torque knob of the controller is adjusted to the required torque value. The torsional shear bolt sets the main engine positive and negative switch to the positive rotation position, and sets the wrench sleeve on the Six Party of the threaded connector.
3, twist shear bolt press power switch, wrench start. When the counterforce support arm is supported by the support (the supporting point can be a nearby bolt or other supporting position) the bolt is started to tighten. When the bolt torque reaches the predetermined torque, the wrench stops automatically and tightens, and the power switch is loosened to tighten the next bolt.
4. After the torsion shear bolt wrench stops automatically, the force arm of the support is automatically detached from the fulcrum and the wrench is removed by the elastic deformation force of the reaction support. If the force arm can not be detached from the fulcrum, the positive and negative switch can be activated, and the wrench of the power switch can be moved down.
