电动扭剪扳手的使用和维护需要遵守的规则

电动扭剪扳手主要用于钢结构安装行业,专门安装钢结构高强度螺栓。高强度螺栓用于连接钢结构的节点,通常采用螺栓组的形式。

The electric torsional shear wrench is mainly used in the steel structure installation industry, specially for the installation of high-strength bolts of steel structure. High strength bolts are used to connect the joints of steel structures, usually in the form of bolt groups.
按照施工工艺,高强螺栓分为扭剪型高强螺栓和大六角高强螺栓。它的连接性能和自身的机械性能是一样的,只是形状不同,螺栓的轴向力由扭矩决定。
According to the construction process, high-strength bolts are divided into torsional shear high-strength bolts and large hexagon high-strength bolts. Its connection performance is the same as its own mechanical performance, but its shape is different. The axial force of the bolt is determined by the torque.
先拧紧高强度螺栓再拧紧,初紧一般为拧紧力矩的一半,终紧必须拧紧到力矩值。大六角高强度螺栓在外观上与普通螺钉相似。冲击扳手可用于初紧,而具有恒定扭矩的电动扳手必须用于终紧。但是扭剪型高强度螺栓前面有一个梅花头,初紧可以用冲击扳手,终紧必须用电动扭剪扳手。电动扭剪扳手可以更精确的控制拧紧扭矩,扭矩可以通过螺栓固定,当扳手达到一定扭矩时,就可以切断螺栓的梅花头部分。恒扭矩螺栓的V型缺口保证了扭矩精度和轴向张力。
First tighten the high-strength bolts and then tighten them. The initial tightening is generally half of the maximum tightening torque, and the final tightening must be tightened to the maximum torque value. Large hexagon high-strength bolt is similar to ordinary screw in appearance. Electric wrench with constant torque for initial tightening and for final tightening. However, there is a plum blossom head in front of the torsion shear high-strength bolt. The impact wrench can be used for initial tightening, and the electric torsion shear wrench must be used for final tightening. The electric torsion shear wrench can more accurately control the tightening torque. The torque can be fixed by bolts. When the wrench reaches a certain torque, the plum blossom head of the bolt can be cut off. The V-notch of constant torque bolt ensures torque accuracy and axial tension.
电动扭剪扳手配有内外套筒、外套筒螺母,外套筒螺母向螺栓施加扭矩,内套筒向方向转动梅花头。两个扭矩大小相等,方向相反,直到尾部的梅花头拧下来,读出预拉力值。
The electric torsion shear wrench is equipped with inner and outer sleeves and outer sleeve nuts. The outer sleeve nuts apply torque to the bolts, and the inner sleeve rotates the Torx head in the direction. The two torques are equal in size and opposite in direction until the plum blossom head at the tail is screwed off and the pre tension value is read out.
电动扭剪扳手体积小,重量轻,距小,适合狭小空间作业。速度快,扭矩大,刚性强,适用于高摩擦系数、超高强度的螺栓紧固。
The electric torsional shear wrench has the advantages of small volume, light weight and small center distance. It is suitable for operation in a narrow space. Fast speed, large torque and strong rigidity. It is suitable for bolt fastening with high friction coefficient and ultra-high strength.
电动扭剪扳手功能:终紧扭剪型高强度螺栓。
Function of electric torsional shear wrench: final tightening torsional shear type high-strength bolt.
应用:越来越多的钢结构需要扭剪型高强度螺栓,必须使用电动扭剪扳手紧固扭剪型高强度螺栓。
Application: more and more steel structures need torsional shear high-strength bolts, and electric torsional shear wrench must be used to fasten torsional shear high-strength bolts.
电动扭剪扳手是钢结构中安装高强度螺栓的专用电动扳手,专门用于拧紧扭转剪切高强度螺栓。产品广泛应用于电力建设、高层建筑、桥梁建设、化工、厂房、冶金、铁路建设等钢结构安装工程。
Electric torsional shear wrench is a special electric wrench for installing high-strength bolts in steel structure, which is specially used to tighten torsional shear high-strength bolts. Products are widely used in power construction, high-rise buildings, bridge construction, chemical industry, plant, metallurgy, railway construction and other steel structure installation projects.
电动扭剪扳手的使用:
Use of electric torsion shear wrench:
工作时,将扳手的套筒头对准螺栓头,拉动开关开始工作。几秒钟后,螺栓的梅花头将被拧掉。这时,拔出扳手,扣动扳机,弹出梅花头,即结束工作。
When working, align the socket head of the wrench with the bolt head, and pull the switch to start working. After a few seconds, the plum blossom head of the bolt will be screwed off. At this time, pull out the wrench, pull the trigger and pop up the plum blossom head, that is to end the work.
更换套筒:
Replace the sleeve:
1.先松开外套管的定位顶紧螺钉,取出内套和外套管。
1. First loosen the positioning jacking screw of the outer sleeve and take out the inner sleeve and outer sleeve.
2.先安装内套(按压顶芯并将其平稳安装到内套中),然后安装相应的外套。
2. First install the inner sleeve (press the top core and install it into the inner sleeve smoothly), and then install the corresponding outer sleeve.
3.将内外套筒安装到末端,并拧紧两个定位螺钉。
3. Install the inner and outer sleeves to the end and tighten the two set screws.
定期检查和维护:
Regular inspection and maintenance:
1.定期检查电源线。
1. Check the power cord regularly.
2.定期检查各部分螺丝,注意电机声音。
2. Regularly check the screws of each part and pay attention to the sound of the motor.
3.确保内外套筒和机器内部没有杂物进入。
3. Make sure that there are no sundries in the inner and outer sleeves and inside the machine.
4.每次操作后,应存放在干净干燥的地方。
4. Store in a clean and dry place after each operation.
