電動扳手就是以電源或電池為動力的扳手，是一種擰緊螺栓的工具。主要分為沖擊扳手、扭剪扳手、定扭矩扳手、轉角扳手、角向扳手、液壓扳手、扭力扳手、充電式電動扳手。
Electric wrench is a power supply or battery powered wrench, is a tool to tighten bolts. It is mainly divided into impact wrench, torsion wrench, constant torque wrench, angle wrench, angle wrench, hydraulic wrench, torque wrench and rechargeable electric wrench.
電動扳手應用領域
Application field of 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。
Electric wrench is mainly used in the steel structure installation industry, specially for the installation of steel structure high-strength bolts. High strength bolts are used to connect steel structure joints, usually in the form of bolt group. High strength bolts can be divided into two types: torsional shear type and large hexagon type. National standard torsional shear type high strength bolts are M16, M20, M22 and M24, and non national standard M27 and M30; The national standard large hexagon high strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the high-strength bolts should be tightened first and then finally, and each step needs to have strict torque requirements. Constant torque wrench must be used for the initial tightening and final tightening of large hexagon high strength bolts. Therefore, all kinds of electric wrench are for all kinds of tightening needs.
電動扳手使用效果
Application effect of electric wrench
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 to tighten the bolt initially. Its use is very simple, that is, to align the bolt and pull the power switch. The electric wrench is mainly used to tighten the high-strength bolt. Its use is to align the bolt and pull the power switch until the quincunx head of the high-strength bolt is broken. The electric constant torque wrench can be used for both initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts. Electric angle wrench is also a kind of fixed torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolt. The electric angle wrench is a kind of electric wrench which is specially used to fasten the bolts in the angle part of the steel frame. Its use principle is the same as that of the electric torsional shear wrench.
