擰緊扭剪型高強(qiáng)螺栓是否一定要使用扭剪型電動(dòng)扳手？
Is it necessary to use a torsional shear electric wrench to tighten torsional shear high-strength bolts?
扭剪型高強(qiáng)螺栓需要使用扭剪扳手，因?yàn)榕ぜ袈菟〝Q緊需要折斷其梅花頭 ，只有扭剪電動(dòng)扳手才能剪斷梅花頭，在擰緊之前，先擰緊高強(qiáng)度螺栓，扭剪螺栓的初擰可以選沖擊電動(dòng)扳手，定扭矩電動(dòng)扳手或扭剪初緊扳手，一般達(dá)到擰緊的50-60%的扭矩就足夠了。
Torsional shear type high-strength bolts need to use a torsional shear wrench, because the torsional shear bolt needs to break its plum blossom head. Only the torsional shear electric wrench can cut the plum blossom head. Before tightening, tighten the high-strength bolt first. For the initial tightening of torsional shear bolts, impact electric wrench, constant torque electric wrench or torsional shear initial tightening wrench can be selected. Generally, 50-60% of the tightening torque is enough.
很多工廠在進(jìn)行日常工業(yè)生產(chǎn)時(shí)都會(huì)用到各種各樣的電子設(shè)備，其中比較常見的就是電動(dòng)扭剪扳手，這種設(shè)備的主要功能就是利用電能通過高速運(yùn)轉(zhuǎn)的驅(qū)動(dòng)裝置使螺絲得到擰緊，那么應(yīng)該如何利用電動(dòng)扭剪扳手進(jìn)行擰緊？有哪些注意事項(xiàng)呢？
Many factories will use a variety of electronic equipment in daily industrial production, among which the more common is the electric torsional shear wrench. The main function of this equipment is to use electric energy to tighten the screws through the high-speed driving device. So how should we use the electric torsional shear wrench to tighten? What are the precautions?
電動(dòng)扭剪扳手的擰緊操作
Tightening operation of electric torsion shear wrench
1.安裝反作用力支架并擰緊螺釘。起動(dòng)主機(jī)，使方頭銷孔與反作用力支撐孔相對應(yīng)，然后安裝扳手套筒，插入銷并用橡膠圈固定。
1. Install the reaction support and tighten the screws. Start the main engine so that the square head pin hole corresponds to the reaction force support hole, then install the wrench socket, insert the pin and fix it with a rubber ring.
2.將控制器的扭矩旋鈕調(diào)整到所需的扭矩值，將主機(jī)的前進(jìn)和后退開關(guān)轉(zhuǎn)到前進(jìn)位置，將扳手套筒放在螺紋接頭的六角上。
2. Adjust the torque knob of the controller to the required torque value, turn the forward and backward switches of the host to the forward position, and place the wrench socket on the hexagon of the threaded joint.
3.按下電源開關(guān)，電動(dòng)扭剪扳手啟動(dòng)。當(dāng)反作用力支架的力臂牢固地靠在支架上時(shí)（支點(diǎn)可以是相鄰的螺栓或可用作支點(diǎn)的其他位置），螺栓開始擰緊。當(dāng)螺栓扭矩達(dá)到預(yù)定扭矩時(shí)，扳手將自動(dòng)停止，擰緊完成，松開電源開關(guān)并擰緊下一個(gè)螺栓。
3. Press the power switch to start the electric torsion shear wrench. When the force arm of the reaction support rests firmly on the support (the fulcrum can be an adjacent bolt or other position that can be used as a 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. 電動(dòng)扭剪扳手自動(dòng)停止后，反作用支架的彈性變形力使支撐力臂自動(dòng)與支點(diǎn)分離，并拆下扳手。如果力臂無法與支點(diǎn)分離，則轉(zhuǎn)動(dòng)正極和負(fù)極開關(guān)，然后單擊電源開關(guān)扳手將其拆下。
4. After the electric torsion shear wrench stops automatically, the elastic deformation force of the reaction support will automatically separate the support arm from the fulcrum, and remove the wrench. If the force arm cannot be separated from the fulcrum, turn the positive and negative switches, and then click the power switch wrench to remove them.
電動(dòng)扭剪扳手使用注意事項(xiàng)
Precautions for use of electric torsion shear wrench
1.螺栓直徑的大小對控制精度有一定影響。在施工過程中，應(yīng)使用相同類型的螺栓連接副校準(zhǔn)扭矩值，并在使用一段時(shí)間后進(jìn)行檢查和校準(zhǔn)。
1. The bolt diameter has a certain impact on the control accuracy. During construction, the same type of bolt connection pair shall be used to calibrate the torque value, and shall be checked and calibrated after use for a period of time.
2.工作前啟動(dòng)并空轉(zhuǎn)3-5分鐘。運(yùn)行中如發(fā)現(xiàn)電機(jī)火花大、異響、扭矩不穩(wěn)定，應(yīng)立即停機(jī)檢查，不得帶病工作，必要時(shí)還需要對線路進(jìn)行檢查，避免線路出現(xiàn)短路的情況。
2. Start and idle for 3-5 minutes before operation. In case of large spark, abnormal noise and unstable torque of the motor during operation, it shall be shut down immediately for inspection. It is not allowed to work with diseases. If necessary, it is also necessary to check the line to avoid short circuit.
3.定期清潔和更換潤滑脂。一般情況下，在運(yùn)行5000次后，清潔并加油一次，以延長使用壽命，同時(shí)也要對設(shè)備的內(nèi)部線路進(jìn)行檢查，如果發(fā)現(xiàn)內(nèi)部線路有破損的情況應(yīng)當(dāng)及時(shí)進(jìn)行零部件的更換。
3. Clean and replace lubricating grease regularly. Generally, after 5000 times of operation, clean and refuel once to prolong the service life. At the same time, check the internal circuit of the equipment. If the internal circuit is damaged, replace the parts in time.
4.主機(jī)控制儀表上的電源開關(guān)、碳刷、保險(xiǎn)絲等為易損件，容易引起故障，應(yīng)經(jīng)常檢查并及時(shí)更換，尤其是保險(xiǎn)絲，一定要在檢查時(shí)做到萬無一失。
4. The power switch, carbon brush and fuse on the host control instrument are vulnerable parts, which are easy to cause faults. They should be checked frequently and replaced in time, especially the fuse, which must be safe during inspection.
5.搬運(yùn)工具時(shí)，不要提起電纜，注意輕放，防止振動(dòng)和墜落。不使用電動(dòng)扭剪扳時(shí)，應(yīng)把它放在通風(fēng)干燥的地方。如果發(fā)現(xiàn)設(shè)備存在水分，應(yīng)及時(shí)對其進(jìn)行干燥處理。不要接觸或儲(chǔ)存酸、堿和其他有害物質(zhì)和氣體。
5. When handling tools, do not lift the cable, and pay attention to handle it gently to prevent vibration and falling. When the electric torsion shear wrench is not used, it should be placed in a ventilated and dry place. If moisture is found in the equipment, it shall be dried in time. Do not store in contact with acids, alkalis and other harmful substances.
