Unlike the fixed torque electric wrench, it needs to check the accuracy and accuracy of the torque. The torque electric wrench only breaks the ring head of the high-strength bolt, which is the purpose of its work.

因?yàn)榕ぜ粜碗妱?dòng)扳手在使用時(shí)，將扭剪型電動(dòng)扳手頭對準(zhǔn)扭剪型高強(qiáng)螺栓頭，扣動(dòng)開關(guān)即可開始工作，幾秒后，螺栓梅花頭將被扭斷，抽出扳手扣動(dòng)扳機(jī)將梅花頭彈出，即結(jié)束工作。電動(dòng)扳手主要應(yīng)用于鋼結(jié)構(gòu)安裝行業(yè)，專門安裝鋼結(jié)構(gòu)高強(qiáng)螺栓，高強(qiáng)度螺栓是用來連接鋼結(jié)構(gòu)接點(diǎn)的，通常是用螺栓群的方式出現(xiàn)。高強(qiáng)螺栓可分為扭剪型和大六角型兩種，國標(biāo)扭剪型高強(qiáng)螺栓為M16、M20、M22、M24四種，現(xiàn)在也有非國標(biāo)的M27、M30兩種；國標(biāo)大六角高強(qiáng)螺栓為M16、M20、M22、M24、M27、M30等幾種。一般的對于高強(qiáng)螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴(yán)格的扭矩要求。扭剪型高強(qiáng)螺栓的初緊可使用沖擊電動(dòng)扳手或定扭矩扳手,而終緊必須使用扭剪扳手;大六角高強(qiáng)螺栓的初緊和終緊都必須使用定扭矩扳手.故各種電動(dòng)扳手就是為各種緊固需要而來的。

Because when the electric wrench is used, align the head of the electric wrench with the head of the high-strength bolt, and then turn the switch to start working. After a few seconds, the bolt ring head will be broken. Pull out the wrench and pull the trigger to pop out the ring head, and then the work will be finished. Electric spanner is mainly used in steel structure installation industry. It is specially used to install high-strength bolts of steel structure. High strength bolts are used to connect steel structure joints, usually in the way of bolt group. High strength bolts can be divided into two types: torsional shear type and large hexagon type. There are four kinds of national standards: M16, M20, M22 and M24. Now there are two kinds of non-national standards: M27 and M30. The national standards are M16, M20, M22, M24, M27 and M30. Generally, for the fastening of high-strength bolts, the initial tightening and then the final tightening are required, and strict torque requirements are required for each step. The impact electric wrench or constant torque wrench can be used for the initial tightening of high-strength bolt of torsional shear type, while the torsional shear wrench must be used for the final tightening; the constant torque wrench must be used for the initial tightening and final tightening of large hexagon high-strength bolt, so all kinds of electric wrenches are for various tightening needs.

沖擊電動(dòng)扳手主要是初緊螺栓的，它的使用很簡單，就是對準(zhǔn)螺栓扳動(dòng)電源開關(guān)就行。電動(dòng)扭剪扳手主要是終緊扭剪型高強(qiáng)螺栓的，它的使用就是對準(zhǔn)螺栓扳動(dòng)電源開關(guān)，直到把扭剪型高強(qiáng)螺栓的梅花頭打斷為止。電動(dòng)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(dòng)轉(zhuǎn)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(zhuǎn)度數(shù)，再緊固螺栓。電動(dòng)角向扳手是一種專門緊固鋼架夾角部位螺栓的電動(dòng)扳手，它的使用和電動(dòng)扭剪扳手原理一樣。

The impact electric wrench is mainly used to tighten the bolt initially. Its use is very simple, that is to align the bolt and pull the power switch. The electric torque wrench is mainly used to tighten the torque shear type high-strength bolt. Its use is to align the bolt and pull the power switch until the plum head of the torque shear type high-strength bolt is interrupted. The electric constant torque wrench can be used for initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts. The electric angle wrench is also a kind of fixed torque wrench. Its use is to adjust the rotation degree first and then fasten the bolts. The electric angle wrench is a kind of electric wrench specially used to fasten the bolts in the angle part of the steel frame. Its use is the same as the principle of the electric torsional shear wrench.

電動(dòng)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(shí)能比較準(zhǔn)確地控制擰緊扭矩。利用螺栓定扭矩，當(dāng)扳手達(dá)到一定扭矩時(shí)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(xiǎn)可靠。方便、美觀、實(shí)用、便于隨車攜帶。廣泛用于鋼結(jié)構(gòu)橋梁、廠房、發(fā)電設(shè)備等設(shè)施的施工作業(yè)。

As the name implies, the electric wrench is a necessary tool for the tightening operation of the box head bolt of the torsional shear. It helps you to install and remove the bolt and nut, and at the same time, it can control the tightening torque more accurately. When the spanner reaches a certain torque, the ring head of the bolt can be cut off. The torque accuracy and axial tension are guaranteed by the V-notch of the bolt. The assembly and disassembly torque is large, more safe and reliable than manual operation. Convenient, beautiful, practical and easy to carry with the car. It is widely used in the construction of steel structure bridge, workshop, power generation equipment and other facilities.

電動(dòng)扳手的特點(diǎn)：（1）使用壽命長（2）手柄和機(jī)殼材料散熱性好（3）功率大（4）耐撞擊性強(qiáng)（5）手使用性價(jià)比

Features of electric wrench: (1) long service life (2) good heat dissipation of handle and shell material (3) high power (4) strong impact resistance (5) cost performance of hand use

電動(dòng)扭剪扳手是一種終緊扭剪型高強(qiáng)度螺栓的工具，一般有電動(dòng)扭剪扳手和手動(dòng)扭剪扳手，其中電動(dòng)扭剪扳手比較常見。

Electric wrench is a kind of tool for final tightening of high-strength bolts. Generally, there are electric wrench and manual wrench, among which electric wrench is common.

扭剪扳手的應(yīng)用：  扭剪型高強(qiáng)螺栓的初緊可使用沖擊電動(dòng)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(qiáng)螺栓的。

Application of torque wrench: impact electric wrench or constant torque wrench can be used for the initial tightening of torque shear type high-strength bolt, while torque wrench must be used for final tightening, so torque wrench is specially used for final tightening of torque shear type high-strength bolt.

扭剪扳手的使用：  扭剪扳手主要是終緊扭剪型高強(qiáng)螺栓的，它的目的就是把扭剪型高強(qiáng)螺栓的梅花頭打斷即可。工作時(shí)將扳手頭對準(zhǔn)螺栓頭，扣動(dòng)開關(guān)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(dòng)扳機(jī)將梅花頭彈出，即結(jié)束工作。

Use of the wrench: the wrench is mainly used to tighten the high-strength bolt. Its purpose is to break the ring head of the bolt. When working, align the spanner head with the bolt head, and turn the switch to start working. After a few seconds, the bolt ring head will be broken, and then pull out the spanner to turn the trigger to pop out the ring head, which is the end of the work.
