  扭剪扳手使用注意事項

  Cautions for Use of Torsion Spanners
  1、拉扳手時用力要柔和均勻。絕對不要用短促、沖動的力來扳動,因為猛拉會產生一個沖量,在停止用力的瞬間,螺釘或螺栓可能已經扭過了頭。
  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、污染物會妨礙得到精確的扭矩值。如果零件和螺孔有污染物,將不可能有正確的扭矩值。
  2. Pollutants will hinder the accurate torque values. If the parts and screw holes are contaminated, there will be no correct torque value.
  3、摩擦是普遍存在的現象,但也有好壞兩方面的作用。好的方面是使得零件保持結合在一起;壞的方面是,在扭緊時,它可能帶來錯誤結果。一個技工用手擰緊聯接的力只有10%—20%用于拉緊方面,而在很多情況下,有40%—50%的扭矩是用來克服螺栓頭和零件之間的摩擦的,沿螺栓和螺孔的配偶螺紋表面還產生附加的摩擦。所以在擰緊螺栓時,應把所有這些摩擦因素以及其它一些因素都考慮進去。
  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、在擰緊螺紋上有損傷或障礙的螺母或螺栓時,要注意通過損傷部位需要附加的扭矩有多大,將此附加扭矩加到推薦的扭矩值上。
  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.

  Performance of Torsion-shear Electric Spanner
  電動扭剪扳手顧名思義就是扭剪梅花頭螺栓擰緊作業的必備工具,幫助您裝、拆螺拴、螺母,同時能比較準確地控制擰緊扭矩。利用螺栓定扭矩,當扳手達到一定扭矩時即可剪斷螺栓的梅花頭部分,其扭矩精度和軸向拉力是靠螺栓的定扭矩V型切口來保證的。拆裝扭力矩大、比手工更保險可靠。方便、美觀、實用、便于隨車攜帶。廣泛用于鋼結構橋梁、廠房、發電設備等設施的施工作業。
  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.
  電動扳手的特點:(1)使用壽命長(2)手柄和機殼材料散熱性好(3)功率大(4)耐撞擊性強(5)手使用性價比比較高
  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.
  扭剪型電動扳手是一種終緊扭剪型高強度螺栓的工具,一般有電動扭剪扳手和手動扭剪扳手,其中電動扭剪扳手比較常見。
  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.
  扭剪扳手的應用: 扭剪型高強螺栓的初緊可使用沖擊電動扳手或定扭矩扳手,而終緊必須使用扭剪扳手,所以扭剪扳手是專門終緊扭剪型高強螺栓的。
                            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: 扭剪扳手主要是終緊扭剪型高強螺栓的,它的目的就是把扭剪型高強螺栓的梅花頭打斷即可。工作時將扳手頭對準螺栓頭,扣動開關即可開始工作,幾秒后,螺栓梅花頭將被扭斷,然后抽出扳手扣動扳機將梅花頭彈出,即結束工作。
  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.
  扭剪扳手的特點: 操作方便、省時省力、安全方便。
  The characteristics of the torsion shear wrench are easy to operate, time-saving and labor-saving, safety and convenience.
