  扭剪扳手使用注意事项

  Cautions for Use of Torsion Spanners
  1、拉扳手时用力要柔和均匀。绝对不要用短促、冲动的力来扳动,因为猛拉会产生一个冲量,在停止用力的瞬间,螺钉或螺栓可能已经扭过了头。
  1. Pull the wrench gently and evenly. Never use short, impulsive force to pull, because a sudden pull will produce an impulse, in the moment of stopping the force, the screw or bolt may have twisted too much.
  2、污染物会妨碍得到精确的扭矩值。如果零件和螺孔有污染物,将不可能有正确的扭矩值。
  2. Pollutants will hinder the accurate torque values. If the parts and screw holes are contaminated, there will be no correct torque value.
  3、摩擦是普遍存在的现象,但也有好坏两方面的作用。好的方面是使得零件保持结合在一起;坏的方面是,在扭紧时,它可能带来错误结果。一个技工用手拧紧联接的力只有10%—20%用于拉紧方面,而在很多情况下,有40%—50%的扭矩是用来克服螺栓头和零件之间的摩擦的,沿螺栓和螺孔的配偶螺纹表面还产生附加的摩擦。所以在拧紧螺栓时,应把所有这些摩擦因素以及其它一些因素都考虑进去。
  3. Friction is a common phenomenon, but it also has good and bad effects. The good thing is to keep the parts together; the bad thing is that it can lead to incorrect results when tightened. In many cases, 40%-50% of the torque is used to overcome the friction between the bolt head and the parts. Additional friction occurs along the thread surface of the spouse bolt and the hole. Therefore, all these friction factors and other factors should be taken into account when tightening the bolts.
  4、在拧紧螺纹上有损伤或障碍的螺母或螺栓时,要注意通过损伤部位需要附加的扭矩有多大,将此附加扭矩加到推荐的扭矩值上。
  4. When tightening nuts or bolts with damages or obstacles on threads, attention should be paid to how much additional torque is required to pass through the damaged parts, and this additional torque should be added to the recommended torque value.
  扭剪型电动扳手性能
  Performance of Torsion-shear Electric Spanner
  电动扭剪扳手顾名思义就是扭剪梅花头螺栓拧紧作业的必备工具,帮助您装、拆螺拴、螺母,同时能比较准确地控制拧紧扭矩。利用螺栓定扭矩,当扳手达到一定扭矩时即可剪断螺栓的梅花头部分,其扭矩精度和轴向拉力是靠螺栓的定扭矩V型切口来保证的。拆装扭力矩大、比手工更保险可靠。方便、美观、实用、便于随车携带。广泛用于钢结构桥梁、厂房、发电设备等设施的施工作业。
  As the name implies, the electric twist shear wrench is a necessary tool for twisting and shearing plum head bolts tightening operation. It can help you install and disassemble bolts and nuts, and control tightening torque more accurately. The plum blossom head of the bolt can be cut when the wrench reaches a certain torque by using the fixed torque of the bolt. The accuracy of the torque and the axial tension of the plum blossom head can be guaranteed by the V-notch of the fixed torque of the bolt. The disassembly and assembly torque is bigger and safer than manual. Convenient, beautiful, practical, easy to carry on the car. It is widely used in the construction of steel structure bridges, factory buildings, power generation equipment and other facilities.
  电动扳手的特点:(1)使用寿命长(2)手柄和机壳材料散热性好(3)功率大(4)耐撞击性强(5)手使用性价比最高
  The characteristics of electric wrench are: (1) long service life (2) good heat dissipation of handle and shell materials (3) high power (4) strong impact resistance (5) the highest cost performance of hand use.
  扭剪型电动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。
  Twist-shear electric wrench is a tool for ultimate tightening and high strength bolts. There are generally electric and manual twist-shear wrenches, among which electric twist-shear wrenches are 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。
                            扭剪扳手
  Application of Torsion-shear wrench: The initial tightening of Torsion-shear high-strength bolt can use impact electric wrench or fixed-torque wrench, and the final tightening must use Torsion-shear wrench, so the Torsion-shear wrench is specially designed for the final tightening of Torsion-shear high-strength bolt.
  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 torsion shear wrench: The main purpose of torsion shear wrench is to break the plum blossom head of torsion shear high strength bolt. When working, the wrench head is aligned with the bolt head, and the switch can start to work. After a few seconds, the bolt plum head will be twisted off, and then pull out the wrench to pull the trigger and pop the plum head out, that is to say, the work will be finished.
  扭剪扳手的特点: 操作方便、省时省力、安全方便。
  The characteristics of the torsion shear wrench are easy to operate, time-saving and labor-saving, safety and convenience.
