电动扳手是扳手的一种,电动扳手就是以电源或电池为动力的扳手,是一种拧紧螺栓的工具。电动扳手分类:主要分为冲击扳手、扭剪扳手、定扭矩扳手、转角扳手、角向扳手、液压扳手、扭力扳手、充电式电动扳手。    
Electric wrench is a kind of wrench. Electric wrench is a wrench driven by power supply or battery. It is a tool for tightening bolts. Electric wrench classification: mainly divided into impact wrench, twist shear wrench, constant torque wrench, angle wrench, angle wrench, hydraulic wrench, torque wrench, rechargeable electric wrench.    
下面,就为您介绍电动扳手操作注意事项及电动扳手保养:    
The following, for you to introduce electric wrench operation precautions and electric wrench maintenance:
电动扳手使用和操作注意事项  
Use and operation precautions of electric wrench
1、确认现场所接电源与电动扳手铭牌是否相符。是否接有漏电保护器。 
1. Confirm whether the power supply connected on site is consistent with the electric wrench nameplate. Whether there is leakage protector.  
2、根据螺帽大小选择匹配的套筒,并妥善安装。  
2. Select the matching sleeve according to the nut size and install it properly.  
3、在送电前确认电动扳手上开关断开状态,否则插头插入电源插座时电动扳手将出其不意地立刻转动,从而可能招致人员伤害危险。  
3. Before power transmission, make sure that the switch on the electric wrench is disconnected, otherwise the electric wrench will turn suddenly when the plug is inserted into the power socket, which may cause personal injury.  
4、若作业场所在远离电源的地点,需延伸线缆时,应使用容量足够,安装合格的延伸线缆。延伸线缆如通过人行过道应高架或做好防止线缆被碾压损坏的措施。  
4. If the working place is far away from the power supply, the extension cable with sufficient capacity and qualified installation shall be used. If the extension cable passes through the pedestrian aisle, it should be elevated or take measures to prevent the cable from being crushed and damaged.  
5、尽可能在使用时找好反向力距支靠点,以防反作用力伤人。  
5. Try to find the support point of the reverse force distance when using, so as to prevent the reaction force from hurting people.  
6、使用时发现电动机碳火花异常时,应立即停止工作,进行检查处理,排除故障。此外碳刷必须保持清洁干净。  
6. When the carbon spark of the motor is abnormal, it should stop working immediately, check and deal with it to eliminate the fault. In addition, carbon brushes must be kept clean.  
7、站在梯子上工作或高处作业应做好高处坠落措施,梯子应有地面人员扶持。 
7. When working on a ladder or working at a high place, falling measures shall be taken, and the ladder shall be supported by ground personnel.

电动扳手检验试验及保养  
Inspection, test and maintenance of electric wrench
1电动扳手的金属外壳应可靠接地,其外壳应有定期检验试验合格证,并在有效期限内。  
1. The metal shell of the electric wrench shall be reliably grounded, and its shell shall be provided with periodic inspection and test certificate, which shall be within the validity period.  
2检查电动扳手机身安装螺钉紧固情况,若发现螺钉松了,应立即重新扭紧,否则会导致电动扳手故障。  
2. Check the tightening condition of the mounting screw of the electric wrench body. If the screw is found to be loose, it should be re tightened immediately, otherwise, the electric wrench will fail.  
3检查手持电动扳手两侧手柄完好,不开裂可破损,安装牢固。    
3. Check that the handles on both sides of the hand-held electric wrench are in good condition and can not be damaged and installed firmly.

电动扭剪扳手是一种终紧扭剪型高强度螺栓的工具,一般有电动扭剪扳手和手动扭剪扳手,其中电动扭剪扳手比较常见。  
The electric twist shear wrench is a kind of tool for the final tightening of high-strength bolts. Generally, there are electric wrench and manual wrench, among which the electric wrench is more common.  
扭剪扳手的应用:  扭剪型高强螺栓的初紧可使用冲击电动扳手或定扭矩扳手,而终紧必须使用扭剪扳手,所以扭剪扳手是专门终紧扭剪型高强螺栓的。  
Application of torsion shear wrench: the impact electric wrench or constant torque wrench can be used for the initial tightening of high-strength bolts, while the torsion shear wrench must be used for the final tightening. Therefore, the torsion shear wrench is specially used for the final tightening of the high-strength bolts.  
扭剪扳手的使用:  扭剪扳手主要是终紧扭剪型高强螺栓的,它的目的就是把扭剪型高强螺栓的梅花头打断即可。工作时将扳手头对准螺栓头,扣动开关即可开始工作,几秒后,螺栓梅花头将被扭断,然后抽出扳手扣动扳机将梅花头弹出,即结束工作。  
Use of twist shear wrench: the purpose of the wrench is to break the plum head of the high strength bolt. When working, the wrench head should be aligned with the bolt head, and the switch can be pulled to start the work. After a few seconds, the bolt plum head will be broken, and then pull out the wrench to pull the trigger to pop out the plum head, which is the end of the work.  
扭剪扳手的特点:  操作方便、省时省力、安全方便。   
The characteristics of twist shear wrench: easy to operate, time-saving and labor-saving, safe and convenient.   
电动扳手应用  电动扳手主要应用于钢结构安装行业,专门安装钢结构高强螺栓,高强度螺栓是用来连接钢结构接点的,通常是用螺栓群的方式出现。高强螺栓可分为扭剪型和大六角型两种,国标扭剪型高强螺栓为M16、M20、M22、M24四种,非国标的M27、M30两种;国标大六角高强螺栓为M16、M20、M22、M24、M27、M30等几种。一般的对于高强螺栓的紧固都要先初紧再终紧,而且每步都需要有严格的扭矩要求。大六角高强螺栓的初紧和终紧都必须使用定扭矩扳手.故各种电动扳手就是为各种紧固需要而来的。
Electric wrench application electric wrench is mainly used in the steel structure installation industry, which is specially used to install steel structure high-strength bolts. High strength bolts are used to connect steel structure joints, usually in the form of bolt groups. High strength bolts can be divided into two types: torsion shear type and large hexagon type. There are four kinds of national standard torsional shear high-strength bolts: M16, M20, M22 and M24, and non-national standard M27 and M30; national standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts should be first and then final tightening, and each step needs to have strict torque requirements. Constant torque wrench must be used in the initial and final tightening of large hexagon high strength bolts. Therefore, all kinds of electric spanners are for various tightening needs.
