電動扭剪扳手主要用于鋼結(jié)構(gòu)安裝行業(yè)，專門安裝鋼結(jié)構(gòu)高強度螺栓。高強度螺栓用于連接鋼結(jié)構(gòu)的節(jié)點，通常采用螺栓組的形式。
The electric torsional shear wrench is mainly used in the steel structure installation industry, specially for the installation of high-strength bolts of steel structure. High strength bolts are used to connect the joints of steel structures, usually in the form of bolt groups.
按照施工工藝，高強螺栓分為扭剪型高強螺栓和大六角高強螺栓。它的連接性能和自身的機械性能是一樣的，只是形狀不同，螺栓的軸向力由扭矩決定。
According to the construction process, high-strength bolts are divided into torsional shear high-strength bolts and large hexagon high-strength bolts. Its connection performance is the same as its own mechanical performance, but its shape is different. The axial force of the bolt is determined by the torque.
先擰緊高強度螺栓再擰緊，初緊一般為大擰緊力矩的一半，終緊一定要擰緊到大力矩值。大六角高強度螺栓在外觀上與普通螺釘相似。沖擊扳手可用于初緊，而具有恒定扭矩的電動扳手用于終緊。但是扭剪型高強度螺栓前面有一個梅花頭，初緊可以用沖擊扳手，終緊需要用電動扭剪扳手。電動扭剪扳手可以更準(zhǔn)的控制擰緊扭矩，扭矩可以通過螺栓固定，當(dāng)扳手達到一定扭矩時，就可以切斷螺栓的梅花頭部分。恒扭矩螺栓的V型缺口保證了扭矩精度和軸向張力。
First tighten the high-strength bolts and then tighten them. The initial tightening is generally half of the large tightening torque, and the final tightening must be tightened to the strong torque value. Large hexagon high-strength bolt is similar to ordinary screw in appearance. Impact wrenches can be used for initial tightening, while electric wrenches with constant torque are used for final tightening. However, there is a plum blossom head in front of the torsion shear high-strength bolt. The impact wrench can be used for initial tightening, and the electric torsion shear wrench needs to be used for final tightening. The electric torsion shear wrench can more accurately control the tightening torque. The torque can be fixed by bolts. When the wrench reaches a certain torque, the plum blossom head of the bolt can be cut off. The V-notch of constant torque bolt ensures torque accuracy and axial tension.
電動扭剪扳手配有內(nèi)外套筒、外套筒螺母，外套筒螺母向螺栓施加扭矩，內(nèi)套筒向方向轉(zhuǎn)動梅花頭。兩個扭矩大小相等，方向相反，直到尾部的梅花頭擰下來，讀出預(yù)拉力值。
The electric torsion shear wrench is equipped with inner and outer sleeves and outer sleeve nuts. The outer sleeve nuts apply torque to the bolts, and the inner sleeve rotates the Torx head in the direction. The two torques are equal in size and opposite in direction until the plum blossom head at the tail is screwed off and the pre tension value is read out.
電動扭剪扳手體積小，重量輕，適合狹小空間作業(yè)。速度快，扭矩大，剛性強，適用于高摩擦系數(shù)、超高強度的螺栓緊固。
The electric torsional shear wrench has small volume and light weight, and is suitable for working in a narrow space. Fast speed, large torque and strong rigidity. It is suitable for bolt fastening with high friction coefficient and ultra-high strength.

應(yīng)用：越來越多的鋼結(jié)構(gòu)需要扭剪型高強度螺栓，需要使用電動扭剪扳手緊固扭剪型高強度螺栓。
Application: more and more steel structures need torsional shear high-strength bolts, and electric torsional shear wrenches need to be used to fasten torsional shear high-strength bolts.
電動扭剪扳手是鋼結(jié)構(gòu)中安裝高強度螺栓的專用電動扳手，專門用于擰緊扭轉(zhuǎn)剪切高強度螺栓。產(chǎn)品廣泛應(yīng)用于電力建設(shè)、高層建筑、橋梁建設(shè)、化工、廠房、冶金、鐵路建設(shè)等鋼結(jié)構(gòu)安裝工程。
Electric torsional shear wrench is a special electric wrench for installing high-strength bolts in steel structure, which is specially used to tighten torsional shear high-strength bolts. Products are widely used in power construction, high-rise buildings, bridge construction, chemical industry, plant, metallurgy, railway construction and other steel structure installation projects.
電動扭剪扳手的使用：
Use of electric torsion shear wrench:
工作時，將扳手的套筒頭對準(zhǔn)螺栓頭，拉動開關(guān)開始工作。幾秒鐘后，螺栓的梅花頭將被擰掉。這時，拔出扳手，扣動扳機，彈出梅花頭，即結(jié)束工作。
When working, align the socket head of the wrench with the bolt head, and pull the switch to start working. After a few seconds, the plum blossom head of the bolt will be screwed off. At this time, pull out the wrench, pull the trigger and pop up the plum blossom head, that is to end the work.
更換套筒：
Replace the sleeve:
1.先松開外套管的定位頂緊螺釘，取出內(nèi)套和外套管。
1. First loosen the positioning jacking screw of the outer sleeve and take out the inner sleeve and outer sleeve.
2.先安裝內(nèi)套(按壓頂芯并將其平穩(wěn)安裝到內(nèi)套中)，然后安裝相應(yīng)的外套。
2. First install the inner sleeve (press the top core and install it into the inner sleeve smoothly), and then install the corresponding outer sleeve.
3.將內(nèi)外套筒安裝到末端，并擰緊兩個定位螺釘。
3. Install the inner and outer sleeves to the end and tighten the two set screws.
定期檢查和維護：
Regular inspection and maintenance:
1.定期檢查電源線。
1. Check the power cord regularly.
2.定期檢查各部分螺絲，注意電機聲音。
2. Regularly check the screws of each part and pay attention to the sound of the motor.
3.確保內(nèi)外套筒和機器內(nèi)部沒有雜物進入。
3. Make sure that there are no sundries in the inner and outer sleeves and inside the machine.
