扭剪型电动扳手就是紧固扭剪型高强螺栓的吗?

终紧扭剪型高强螺栓需要用到扭剪型电动扳手。

The final tightening of torsional shear high-strength bolts requires the use of torsional shear electric wrench.
现在高强螺栓的分类分为大六角高强螺栓和扭剪型高强螺栓,每种高强螺栓的紧固都必须先初紧再终紧。
At present, high-strength bolts are classified into large hexagon high-strength bolts and torsional shear high-strength bolts. Each kind of high-strength bolt must be tightened first and then finally.
扭剪型高强螺栓的初紧可以选择冲击电动扳手、定扭矩电动扳手或扭剪型电动初紧扳手,一般达到终紧扭矩的50-60%就可以了。而扭剪型高强螺栓的终紧一定要用扭剪型电动扳手,因为扭剪型高强螺栓的终紧需要把它的梅花头打断。 
The initial tightening of torsional shear high-strength bolts can choose impact electric wrench, constant torque electric wrench or torsional shear electric initial tightening wrench, which generally reaches 50-60% of the final tightening torque. The final tightening of torsional shear high-strength bolt must use torsional shear electric wrench, because the final tightening of torsional shear high-strength bolt needs to break its plum blossom head.  
电动扭剪扳手是装配螺纹件及螺栓的机械化施工工具,具有自动控制扭矩功能。广泛应用于栓焊结构桥梁的架设,厂房、塔架及化工、冶、发电设备的安装。大型机械、起重设备和车辆装配作业,以及对螺纹紧固件的扭矩及轴向拉力有严格要求的场合。
Electric torsional shear wrench is a mechanized construction tool for assembling threaded parts and bolts, which has the function of automatic torque control. It is widely used in the erection of bolted and welded bridges, and the installation of plants, towers and chemical, metallurgical and power generation equipment. Large machinery, lifting equipment and vehicle assembly operations, as well as occasions with strict requirements on the torque and axial tension of threaded fasteners.
电动扭剪扳手螺栓的拧紧操作方法
Tightening operation method of electric torsion shear wrench bolt
1、装上反力支架,并紧固螺钉。开动主机,使方头销孔与反力支架孔相对应,然后装入扳手套筒,插上销钉,并用橡胶圈固定。
1. Install the reaction support and tighten the screws. Start the main engine so that the square head pin hole corresponds to the reaction support hole, then install the wrench socket, insert the pin and fix it with a rubber ring.
2、将控制仪的扭矩旋钮调到所需扭矩值,将主机正反开关拨到正转位置,把扳手套筒套在螺纹连接件的六方上。
2. Adjust the torque knob of the controller to the required torque value, turn the forward and reverse switch of the host to the forward position, and put the wrench socket on the hexagon of the threaded connector.
3、按下电源开关,扳手启动。当反力支架力臂靠牢支架时(支点可以是邻近的一只螺栓或其他可作支点的位置)螺栓开始拧紧。当螺栓扭矩达到预定扭矩时,扳手自动停止,紧固完成,松开电源开关,进行下一只螺栓的拧紧工作。
3. Press the power switch and the wrench starts. When the force arm of the reaction support is firmly against the support (the fulcrum can be an adjacent bolt or other position that can be used as the fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop, the tightening is completed, loosen the power switch and tighten the next bolt.
4、扳手自动停止后,靠反力支架的弹性形变力,使支架力臂自动脱离支点,取下扳手。如力臂不能脱离支点时,可拨动正反开关,点动电源开关扳手即可取下。
4. After the wrench stops automatically, the elastic deformation force of the reaction support makes the support force arm automatically separate from the fulcrum and remove the wrench. If the force arm cannot be separated from the fulcrum, turn the positive and negative switch and click the power switch wrench to remove it.
