本產品是扭剪型螺栓擰緊作業的必備工具，利用螺栓定扭矩V型切口，當扳手達到一定扭矩時即可剪斷螺栓的梅花頭是靠螺栓的定扭矩V型切口來保證的。廣泛應用于鋼結構橋梁、廠房、發電設備等設施的施工作業。
This product is a necessary tool for tightening the torsion-shear bolt. It uses the V-shaped notch with fixed torque of the bolt. When the wrench reaches a certain torque, the Torx head of the bolt can be cut. It is guaranteed by the V-shaped notch with fixed torque of the bolt. It is widely used in the construction of steel structure bridges, workshops, power generation equipment and other facilities.
扭剪型電動扳手螺栓的擰緊操作
Tightening operation of torsion shear type electric wrench bolt
1、裝上反力支架，并緊固螺釘。開動主機，使方頭銷孔與反力支架孔相對應，然后裝入扳手套筒，插上銷釘，并用橡膠圈固定。
1. Install the reaction support and tighten the screws. Start the main engine, make the square head pin hole correspond to the reaction support hole, then install the wrench socket, insert the pin, and fix it with a rubber ring.
2、將控制儀的扭矩旋鈕調到所需扭矩值，將主機正反開關撥到正轉位置，把扳手套筒套在螺紋連接件的六方上。
2. Adjust the torque knob of the controller to the required torque value, turn the forward and reverse switches of the host machine to the forward rotation position, and put the wrench socket on the hexagon of the threaded connection.
3、按下電源開關，扳手啟動。當反力支架力臂靠牢支架時（支點可以是鄰近的一只螺栓或-可作支點的位置）螺栓開始擰緊。當螺栓扭矩達到預定扭矩時，扳手自動停止，緊固完成，松開電源開關，進行下一只螺栓的擰緊工作。
3. Press the power switch and the wrench will start. When the force arm of the reaction support is close to the support (the fulcrum can be an adjacent bolt or the fulcrum position), the bolt starts to tighten. When the bolt torque reaches the predetermined torque, the wrench will stop automatically, and the tightening is completed. Loosen the power switch to tighten the next bolt.
4、扳手自動停止后，靠反力支架的彈性形變力，使支架力臂自動脫離支點，取下扳手。如力臂不能脫離支點時，可撥動正反開關，點動電源開關扳手即可取下。
4. After the wrench stops automatically, the force arm of the support will automatically disengage from the fulcrum by the elastic deformation force of the reaction support, and the wrench will be removed. If the lever arm cannot be separated from the fulcrum, you can toggle the forward and reverse switches, and then jog the power switch wrench to remove it.
扭剪型電動扳手操作注意事項
Precautions for operation of torsion shear type electric wrench
1、螺栓直徑的大小對控制精度有一定的影響，施工中應用相同型號的螺栓連接付來標定扭矩值，而且使用一段時間后還應進行檢驗校定。
1. The size of the bolt diameter has a certain impact on the control accuracy. The same type of bolt connection pair shall be used to calibrate the torque value during construction, and the torque value shall also be checked and calibrated after use for a period of time.
2、工作前應開機空轉3-5分鐘。操作中如發現電機火花大，聲音異常，扭矩不穩定時，應立即停機檢查，切勿帶病工作。
2. Start and idle for 3-5 minutes before work. If the motor is found to have large sparks, abnormal sound and unstable torque during operation, it should be stopped immediately for inspection, and it is not allowed to work with diseases.

3、定期清洗和更換油脂，一般在工作5000次后，應進行一次清洗加油，以延長使用壽命。
3. Clean and replace the grease regularly. Generally, after 5000 times of operation, clean and refuel once to extend the service life.
4、主機上的電源開關，碳刷，控制儀上的保險絲等均屬易損件，容易引起故障，應經常檢查，及時更換。
4. The power switch, carbon brush and fuse on the control instrument on the main machine are all vulnerable parts, which are easy to cause faults. They should be checked frequently and replaced in time.
5、使用中如發現工具上的螺釘松動，應及時緊固。
5. If the screw on the tool is loose during use, it should be fastened in time.
6、搬運工具時不可提拉電纜線，并注意輕拿輕放，防止震動和摔碰。不用時應放在通風干燥處。如發現受潮應及時進行干燥處理。不可與酸、堿等有害物質氣體接觸或存放在一起。
6. When carrying tools, do not pull the cable, and pay attention to handle it gently to prevent vibration and falling. It should be placed in a ventilated and dry place when not in use. In case of moisture, it shall be dried in time. Do not contact or store with acid, alkali and other harmful substances and gases.
扭剪型電動扳手扭矩的選擇與調節
Selection and adjustment of torque of electric wrench with torsion shear
1、用戶可在50-3500Nm的范圍內任意選擇相應規格的扭剪型電動扳手。
1. The user can choose the electric wrench of corresponding specifications in the range of 50-3500Nm.
2、控制儀面板上有“扭矩調解旋鈕”。刻有0-10個刻度值。細調旋鈕的作用是在粗調兩檔之間進行調節補償，以提高扭矩控制精度。
2. There is a "torque adjustment knob" on the control panel. There are 0-10 scale values. The function of fine adjustment knob is to adjust and compensate between the two gears of coarse adjustment to improve the torque control accuracy.
3、調節方法：產品出廠時帶有扭矩測試數據卡片，供用戶標定時參考，用戶可根據所需扭矩選擇某一刻度值，按擰緊螺栓的操作方法，擰緊螺栓，用測力扳手或其它測力儀器測出螺栓的實際扭矩值，若扭矩相差較小，可用細調加以補償，若相差較大，可將粗調向上或向下調一檔，反復幾次即可獲得所需扭矩值。
3. Adjustment method: The product is delivered with a torque test data card for the user's reference during calibration. The user can select a certain scale value according to the required torque, tighten the bolt according to the operation method of tightening the bolt, and measure the actual torque value of the bolt with a force measuring wrench or other force measuring instruments. If the torque difference is small, fine adjustment can be used to compensate. If the difference is large, coarse adjustment can be up or down by one gear, Repeat several times to obtain the required torque value.
