扭剪型電動扳手不像定扭矩電動扳手，需要校驗扭矩的精度，是否準確，扭剪型電動扳手只是將扭剪型高強螺栓的梅花頭打斷，既是完成了它的工作目的。
Unlike fixed torque electric wrenches, torsion shear electric wrenches require verification of torque accuracy. They only break the torx head of high-strength bolts, completing their job purpose.
因為扭剪型電動扳手在使用時，將扭剪型電動扳手頭對準扭剪型高強螺栓頭，扣動開關即可開始工作，幾秒后，螺栓梅花頭將被扭斷，抽出扳手扣動扳機將梅花頭彈出，即結束工作。電動扳手主要應用于鋼結構安裝行業(yè)，專門安裝鋼結構高強螺栓，高強度螺栓是用來連接鋼結構接點的，通常是用螺栓群的方式出現(xiàn)。高強螺栓可分為扭剪型和大六角型兩種，國標扭剪型高強螺栓為M16、M20、M22、M24四種，現(xiàn)在也有非國標的M27、M30兩種；國標大六角高強螺栓為M16、M20、M22、M24、M27、M30等幾種。一般的對于高強螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴格的扭矩要求。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;大六角高強螺栓的初緊和終緊都必須使用定扭矩扳手.故各種電動扳手就是為各種緊固需要而來的。
Because when using a torsion shear electric wrench, align the head of the torsion shear electric wrench with the high-strength bolt head of the torsion shear type, press the switch to start working, and after a few seconds, the bolt ring head will be twisted and broken. Pull out the wrench and pull the trigger to eject the ring head, which ends the work. Electric wrenches are mainly used in the steel structure installation industry, specifically to install high-strength bolts for steel structures. 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: torsional shear type and large hexagonal type. There are four types of national standard torsional shear type high strength bolts: M16, M20, M22, and M24. Currently, there are also two types of non national standard bolts: M27 and M30; The national standard large hexagonal high-strength bolts include M16, M20, M22, M24, M27, M30, and other types. Generally, the tightening of high-strength bolts requires initial tightening before final tightening, and each step requires strict torque requirements. The initial tightening of torsion shear high-strength bolts can be achieved using an impact electric wrench or a fixed torque wrench, while the final tightening must be achieved using a torsion shear wrench; The initial and final tightening of large hexagonal high-strength bolts must use a fixed torque wrench. Therefore, various electric wrenches are designed for various tightening needs.
沖擊電動扳手主要是初緊螺栓的，它的使用很簡單，就是對準螺栓扳動電源開關就行。電動扭剪扳手主要是終緊扭剪型高強螺栓的，它的使用就是對準螺栓扳動電源開關，直到把扭剪型高強螺栓的梅花頭打斷為止。電動定扭矩扳手既可初緊又可終緊，它的使用是先調(diào)節(jié)扭矩，再緊固螺栓。電動轉角扳手主要也屬于定扭矩扳手的一種，它的使用是先調(diào)節(jié)旋轉度數(shù)，再緊固螺栓。電動角向扳手是一種專門緊固鋼架夾角部位螺栓的電動扳手，它的使用和電動扭剪扳手原理一樣。
The impact electric wrench is mainly used for initial tightening of bolts, and its use is very simple, which is to align the bolt and pull the power switch. The electric torque wrench is mainly used for final tightening of torque shear high-strength bolts. Its use is to align the bolt and pull the power switch until the plum blossom head of the torque shear high-strength bolt is broken. The electric fixed torque wrench can be used for both initial and final tightening. Its use involves adjusting the torque first and then tightening the bolts. Electric angle wrenches mainly belong to a type of fixed torque wrench, which is used to adjust the rotation degree first and then tighten the bolts. Electric angle wrench is a type of electric wrench specifically designed to tighten bolts at the angle of a steel frame, and its use is the same as that of an electric torsion wrench.
電動扭剪扳手顧名思義就是扭剪梅花頭螺栓擰緊作業(yè)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(fā)電設備等設施的施工作業(yè)。
The electric torque wrench, as the name suggests, is a necessary tool for tightening the torx head bolt, helping you install and remove bolts and nuts, while accurately controlling the tightening torque. By using bolts to set torque, when the wrench reaches a certain torque, the plum blossom part of the bolt can be cut off. The torque accuracy and axial tension are ensured by the V-shaped notch of the fixed torque of the bolt. The disassembly and assembly torque is large and more secure and reliable than manual work. Convenient, beautiful, practical, and easy to carry with the car. Widely used for construction operations of steel structure bridges, factories, power generation equipment, and other facilities.
