　　定扭矩电动扳手应用行业：

　　Fixed Torque Electric Spanner Application Industry:

　　定扭矩电动扳手广泛应用于栓焊结构桥梁的架设，厂房、塔架及化工、冶金、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。

　　Fixed torque electric wrench is widely used in the erection of bolted and welded structure bridges, plant, tower and installation of chemical, metallurgical and power generation equipment. Large machinery, lifting equipment and vehicle assembly operations, as well as the screw fastener torque and axial tension have strict requirements.

　　定扭矩电动扳手螺栓的拧紧操作

　　Tightening operation of bolts in fixed torque electric wrench1、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 bracket and fasten the screw. Start the main engine, so that the square head pin hole corresponds to the counterforce support hole, and then install the pulling glove barrel, insert the pin, and fix it with the 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. Set the torque knob of the controller to the required torque value, set the positive and negative switch of the main engine to the positive rotation position, and put the wrench glove barrel on the six sides 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 start the wrench. When the reaction bracket arm is firmly attached to the bracket (the fulcrum may be a nearby bolt or other position where it can be used as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench automatically stops, tightens, loosens the power switch, and tightens 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. When the wrench stops automatically, the elastic deformation force of the reaction bracket can make the bracket arm automatically detach from the fulcrum and take down the wrench. If the force arm can not be separated from the fulcrum, the positive and negative switch can be switched, and the power switch wrench can be removed by clicking.

Users can choose the appropriate specifications of the electric fixed Torque Spanner in the range of 50-3500Nm.

　　2、控制仪面板上有“扭矩调解旋钮”。刻有0-10个刻度值。细调旋钮的作用是在粗调两档之间进行调节补偿，以提高扭矩控制精度。（见后页）3、调节方法：产品出厂时带有扭矩测试数据卡片，供用户标定时参考，用户可根据所需扭矩选择某一刻度值，按拧紧螺栓的操作方法，拧紧螺栓，用测力扳手或其它测力仪器测出螺栓的实际扭矩值，若扭矩相差较小，可用细调加以补偿，若相差较大，可将粗调向上或向下调一档，反复几次即可获得所需扭矩值。

　　2. There are “ torque adjustment knob ” on the panel of the controller. It has 0-10 scale values. The function of fine-tuning knob is to adjust and compensate between coarse-tuning gears in order to improve the accuracy of torque control. 3. Adjustment method: When the product leaves the factory, there is a torque test data card for reference when the user calibrates. The user can choose a 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 the force measuring wrench or other force measuring instrument. If the difference of the torque is small, it can be compensated by fine adjustment. If the difference is large, the bolt can be tightened. The required torque value can be obtained by adjusting roughly one gear up or down several times.

　　定扭矩电动扳手操作注意事项

　　Cautions for Operation of Electric Spanner with Fixed Torque1、螺栓直径的大小对控制精度有一定的影响，施工中应用相同型号的螺栓连接付来标定扭矩值，而且使用一段时间后还应进行检验校定。

　　1. The diameter of bolt has a certain influence on the control accuracy. The same type of bolt connection is used to calibrate the torque value in construction, and it should be checked and calibrated after a period of time.

　　2、工作前应开机空转3-5分钟。操作中如发现电机火花大，声音异常，扭矩不稳定时，应立即停机检查，切勿带病工作。

　　2. Turn on and idle for 3-5 minutes before work. If it is found that the spark of the motor is large, the sound is abnormal, and the torque is unstable, the machine should be stopped immediately to check, and do not work with illness.

　　3、定期清洗和更换油脂，一般在工作5000次后，应进行一次清洗加油，以延长使用寿命。

　　3. Clean and replace grease regularly. Generally, after 5000 times of work, it should be cleaned and refueled once to prolong service life.

　　4、主机上的电源开关，碳刷，控制仪上的保险丝等均属易损件，容易引起故障，应经常检查，及时更换。

　　4. The power switch, carbon brush and fuse on the controller on the main engine are all vulnerable parts, which are prone to malfunction. They should be checked regularly and replaced in time.

　　5、使用中如发现工具上的螺钉松动，应及时紧固。

　　5. If the screw on the tool is loose in use, it should be tightened in time.

　　6、搬运工具时不可提拉电缆线，并注意轻拿轻放，防止震动和摔碰。不用时应放在通风干燥处。如发现受潮应及时进行干燥处理。不可与酸、碱等有害物质气体接触或存放在一起。

　　6. When handling tools, do not pull cable, and pay attention to handle lightly to prevent vibration and collision. When not in use, it should be placed in a ventilated and dry place. If dampness is found, drying treatment should be carried out in time. Do not contact or store with harmful substances such as acid or alkali.
