　　SGDD固定扭矩直角电动扳手的应用:SGDD固定扭矩直角电动扳手具有自动控制扭矩的功能，是组装螺纹零件和螺栓的机械化施工工具。手广泛用于大型机械、起重设备和车辆装配作业，以及对螺纹紧固件扭矩和轴向张力有严格要求的场合。

　　Application of SGDD fixed torque right angle electric wrench: SGDD fixed torque right angle electric wrench has the function of automatically controlling torque and is a mechanized construction tool for assembling threaded parts and bolts. Hand is widely used in large machinery, lifting equipment and vehicle assembly operations, as well as where stringent fastener torque and axial tension are critical.

　　SGDD固定扭矩直角电动扳手螺栓1的拧紧操作。

　　Tightening operation of SGDD fixed torque right angle electric wrench bolt 1.

　　1.安装反作用支架并拧紧螺钉。启动主机，使方形销孔与反力支撑孔相对应，然后安装扳手套筒，插入销并用橡胶圈固定。

　　1. Install the reaction bracket and tighten the screws. Start the main machine so that the square pin hole corresponds to the reaction force support hole, then install the wrench sleeve, insert the pin and fix it with a rubber ring.

　　2.将控制仪表的扭矩旋钮调节所需扭矩值，将主机的前进和后退开关设置前进旋转位置，并将扳手套筒设置在螺纹接头的六角体上。

　　2. Adjust the torque knob of the control instrument to the desired torque value, set the forward and reverse switches of the main unit to the forward rotation position, and set the wrench sleeve on the hexagon of the threaded joint.

　　3、按下电源开关，扳手启动。当反作用力支架的力臂牢牢靠在支架上时(支点可以是相邻的螺栓或可用作支点的其他位置)，螺栓开始拧紧。当螺栓扭矩达到预设扭矩时，扳手将自动停止、拧紧、松开电源开关并拧紧下一个螺栓。

　　3. Press the power switch and the wrench starts. When the force arm of the reaction force bracket is firmly against the bracket (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 preset torque, the wrench will automatically stop, tighten, loosen the power switch and tighten the next bolt.

　　4.扳手自动停止后，支架臂通过反力支架的弹性变形力自动脱离支点，扳手被取下。如果力臂不能与支点分离，则可以拨动前进和后退开关，并通过点动方式拆下电源开关扳手。

　　4. After the wrench is automatically stopped, the bracket arm automatically disengages from the fulcrum by the elastic deformation force of the reaction force bracket, and the wrench is removed. If the arm cannot be separated from the fulcrum, you can toggle the forward and reverse switches and remove the power switch wrench by jogging.

　　SGDD固定扭矩直角电动扳手扭矩的选择与调整。

　　SGDD fixed torque right angle electric wrench torque selection and adjustment.

　　1.用户可以在50-3500纳米范围内任意选择相应规格的SGDD固定扭矩直角电动扳手。

　　1. Users can choose SGDD fixed torque right angle electric wrench of the corresponding specification within the range of 50-3500 nm.

　　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。

　　2. There is a “torque adjustment knob” on the panel of the controller. Engraved with 0-10 scale values. The function of the fine adjustment knob is to adjust the compensation between the two coarse adjustments to improve the torque control accuracy.

　　3.调整方法:产品出厂时附有扭矩测试数据卡，供校准时参考。用户可以根据需要的扭矩选择一定的校准值，按照拧紧螺栓的操作方法拧紧螺栓，并用测力扳手或其他测力仪器测量螺栓的实际扭矩值。如果扭矩差很小，可以用微调来补偿；如果差值很大，可以通过一个齿轮向上或向下调节粗调，并且通过重复几次可以获得所需的扭矩值。

　　SGDD固定扭矩直角电动扳手注释操作(需要特别注意)1.接通电源前，检查电源电压是否与本产品铭牌一致，是否有接地装置。当电源电压超过+10%时，应采取稳压措施，否则会影响控制精度。接地不良容易导致事故。

　　2.工具使用的环境温度为-10℃-40℃，过高或过低都会影响控制精度。

　　3.螺纹螺栓的初始扭矩不得大于工具额定扭矩的70%。达到额定扭矩后，不得重新拧紧螺栓。

　　3. The initial torque of the threaded bolt shall not exceed 70% of the rated torque of the tool. Do not retighten the bolts after the rated torque has been reached.

　　4.当工具用于拆卸螺栓时，其扭矩不得大于额定扭矩值。正常情况下，不使用该扳手拧紧或锈蚀严重的螺栓不应使用该扳手拆卸，以避免工具损坏。
                             

　　4. When the tool is used to remove the bolt, its torque must not exceed the rated torque value. Under normal circumstances, bolts that are not tightened or severely corroded with this wrench should not be removed with this wrench to avoid damage to the tool.

　　5、改变旋转方向时，必须等待电机停止旋转，严禁在运行中拨动正负开关。

　　5. When changing the direction of rotation, you must wait for the motor to stop rotating. It is strictly forbidden to toggle the positive and negative switches during operation.

　　6.当扳手自动停止时，可以松开开关(如果开关持续打开，扳手将在5秒钟后自动启动)。4-5秒后启动扳手，否则扳手无法启动。

　　6. When the wrench stops automatically, you can release the switch (if the switch continues to open, the wrench will automatically start after 5 seconds). Start the wrench after 4-5 seconds, otherwise the wrench will not start.

　　SGDD固定扭矩直角电动扳手操作注意事项

　　SGDD fixed torque right angle electric wrench operation precautions1、螺栓直径的大小对控制精度有一定的影响，施工中应使用相同类型的螺栓连接来标定扭矩值，并应在使用一段时间后进行检查和标定。

　　1. The size of the bolt diameter has a certain influence on the control accuracy. The same type of bolt connection should be used to calibrate the torque value during construction, and should be inspected and calibrated after a period of use.

　　2.工作前，打开机器并怠速运转3-5分钟。运行中，如果电机火花大、声音异常、扭矩不稳定，应立即停机检查，不要带病工作。

　　2. Before starting work, turn on the machine and idle for 3-5 minutes. During operation, if the motor has a large spark, abnormal sound, and unstable torque, stop the machine immediately and do not take sick work.

　　3、定期清洗和更换润滑脂，一般在工作5000次后，应进行清洗加油，以延长使用寿命。

　　3, regular cleaning and replacement of grease, generally after 5,000 operations, should be cleaned and refueled to extend the service life.

　　4.主机控制仪表上的电源开关、碳刷和保险丝都是易损件，容易引起故障。应该经常检查并及时更换。

　　4. The power switch, carbon brush and fuse on the main control instrument are all wearing parts, which are easy to cause malfunction. It should be checked frequently and replaced in time.

　　5.如果工具上的螺钉在使用过程中发现松动，应及时拧紧。

　　5. If the screws on the tool are loose during use, tighten them in time.

　　6.搬运工具时不要提起电缆，小心搬运，防止振动和碰撞。不使用时，应将其放置在通风干燥的地方。如果发现水分，应该及时干燥。不要接触或储存有害物质，如酸和碱。

　　6. Do not lift the cable when handling the tool, handle it carefully to prevent vibration and collision. When not in use, place it in a dry, well-ventilated area. If moisture is found, it should be dried in time. Do not touch or store hazardous substances such as acids and bases.
