扭剪型電動扳手介紹
Introduction to Torsion Shear Type Electric 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
As the name implies, the electric torque wrench is a tool for torshear torx head bolt tightening operation, which can help you install and remove bolts and nuts, and control the tightening torque more accurately. The fixed torque of the bolt is used. When the wrench reaches a certain torque, the box head of the bolt can be cut off. The torque accuracy and axial tension depend on the fixed torque V of the bolt
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)。
Type notch. The disassembly torque is large, more reliable than manual. Convenient, beautiful, practical and easy to carry with the vehicle. It is widely used in the construction of steel structure bridges, plants, power generation equipment and other facilities.
扭剪型電動扳手使用特點
Operating Characteristics of Torsion Shear Type Electric Wrench
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，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。大六角高強螺栓的初緊和終緊都使用定扭矩扳手.故各種電動扳手就是為各種緊固需要而來的。
The electric wrench is mainly used in the steel structure installation industry 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: torsional shear type and large hexagon type. The national standard torsional shear type high strength bolts are M16, M20, M22 and M24, and the non national standard M27 and M30; The national standard large hexagon high-strength bolts include M16, M20, M22, M24, M27, M30, etc. Generally, high-strength bolts shall be tightened first and then finally, and each step requires strict torque requirements. Fixed torque wrenches are used for the initial and final tightening of large hexagon high-strength bolts, so various electric wrenches are designed for various tightening needs.

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）手使用性價比高
1) Long service life (2) Good heat dissipation of handle and housing materials (3) High power (4) Strong impact resistance (5) High cost performance
扭剪扳手的應用：
Application of shear wrench:
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手將梅花頭彈出，即結束工作。
The impact electric wrench or constant torque wrench can be used for the initial tightening of the torsional shear type high-strength bolt, while the torsional shear wrench is used for the final tightening, so the torsional shear wrench is specially used for the final tightening of the torsional shear type high-strength bolt. Use of the shear wrench: The shear wrench is mainly used to tighten the shear type high-strength bolt. Its purpose is to break the torx head of the shear type high-strength bolt. When working, align the wrench head with the bolt head, and then click the switch to start working. After a few seconds, the bolt box head will be broken, and then pull out the wrench and click the wrench to pop out the box head, which ends the work.
