定扭矩扳手的注意事项操作介绍

定扭矩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、发电设备的安装,还应用于大型机械、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。

Constant torque wrench is a mechanized construction tool for assembling threaded parts and bolts. It has the function of automatic torque control. It is widely used in the erection of bolt welded structure bridges, the installation of plants, towers, chemical and power generation equipment, as well as the assembly of large machinery, lifting equipment and vehicles, as well as occasions with strict requirements for the torque and axial tension of threaded fasteners.
扭矩扳手由主机和控制仪两部分组成,主机采用电动机和减速机构,结构新颖、体积小、重量轻、安全可靠,由于采用静扭结构,运转平稳,无振动、无冲击,噪音小,操作者不受反力矩的影响,因而劳动强度低。
The torque wrench is composed of a main engine and a controller. The main engine adopts a motor and a reduction mechanism, which has novel structure, small volume, light weight, safety and reliability. Due to the static torsion structure, it operates stably, has no vibration, impact, low noise, and the operator is not affected by the counter torque, so the labor intensity is low.
一、定扭矩扳手的拧紧操作
1、 Tightening operation of constant torque wrench
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, tighten the screws, start the host to 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、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,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 rests firmly against the support, the bolts begin 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 force arm of the support will automatically disengage from the fulcrum by the elastic deformation force of the reaction support, and then 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.
二、注意事项操作
2、 Precautions operation
1、接通电源前应先查看电源电压是否与本国产品铭牌相符,是否有接地装置。当电源电压超出 10%时应采取稳压措施,否则会影响控制精度。接地不良易造成事故。
1. Before connecting the power supply, check whether the power supply voltage is consistent with the nameplate of domestic products and whether there is a grounding device. When the power supply voltage exceeds 10%, voltage stabilizing measures shall be taken, otherwise the control accuracy will be affected. Poor grounding is easy to cause accidents.

2、工具使用的环境温度为-10℃-40℃,过高过低都会影响控制精度。
2. The ambient temperature of the tool is - 10 ℃ - 40 ℃, too high or too low will affect the control accuracy.
3、被拧螺栓的初始扭矩不得大于工具的额定扭矩的70%。螺栓达到额定扭矩后不得重拧。
3. The initial torque of the screwed bolt shall not be greater than 70% of the rated torque of the tool. The bolts shall not be re tightened after reaching the rated torque.
4、工具用于拆卸螺栓时,其扭矩不得大于额定扭矩值。一般情况下,不是本扳手拧紧的或锈蚀严重的螺栓,不宜用本扳手拆卸,以免造成工具损坏。
4. When the tool is used to remove the bolt, its torque shall not be greater than the rated torque. Generally, the bolts that are not tightened or seriously rusted by this wrench should not be removed with this wrench to avoid tool damage.
5、变换旋转方向时,必须待电机停止转动后进行,严禁在运转中拨动正反开关。
5. When changing the rotation direction, it must be carried out after the motor stops rotating. It is strictly prohibited to toggle the positive and negative switches during operation.
6、当扳手自动停止后即可松开开关(如果不断开开关,过5秒钟扳手就会自行启动)待4-5秒后再进行开动扳手,否则扳手不能启动。
6. When the wrench stops automatically, loosen the switch (if the switch is not opened, the wrench will start automatically after 5 seconds). Start the wrench after 4-5 seconds, otherwise the wrench cannot start.
