扭剪螺栓初擰的時(shí)候是不需要設(shè)置扭力的，需要用定扭矩扳手或者沖擊扳手進(jìn)行初緊，扭力達(dá)到60%-80%即可，然后用終緊扭剪扳手進(jìn)行終緊就可以了，終緊扭剪扳手根據(jù)螺栓的大小已經(jīng)設(shè)置好扭力了，不需要自己設(shè)置。套筒根據(jù)螺栓的大小來(lái)選擇，m16-20-22-24-27-30六種國(guó)標(biāo)扭剪螺栓，還有英制，美制，定制螺栓等，除了國(guó)標(biāo)螺栓套筒是現(xiàn)貨，其它一般都需要定制套筒。
There is no need to set the torque during the initial tightening of the torsion shear bolt. It is necessary to use the fixed torque wrench or impact wrench for initial tightening, and the torque can reach 60% - 80%, and then use the final tightening torsion shear wrench for final tightening. The final tightening torsion shear wrench has set the torque according to the size of the bolt, so it is not necessary to set it by itself. The sleeve is selected according to the size of the bolt. There are six kinds of national standard torsion shear bolts m16-20-22-24-27-30, as well as British, American and customized bolts. Except that the national standard bolt sleeve is in stock, others generally need to be customized.
電動(dòng)扭剪扳手使用效果：
Use effect of electric torsion shear wrench:
1、沖擊電動(dòng)扳手主要是初緊螺栓的，它的使用很簡(jiǎn)單，就是對(duì)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螺栓的，它的使用就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開關(guān)，直到把扭剪型螺栓的梅花頭打斷為止。
1. The impact electric wrench is mainly used to initially tighten the bolt. Its use is very simple. Just aim at the bolt and pull the power switch. The electric torsion shear wrench is mainly used to finally tighten the torsion shear bolt. Its use is to align the bolt and pull the power switch until the plum blossom head of the torsion shear bolt is broken.
2、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。電動(dòng)扭剪扳手拆裝扭力矩大、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、高層建筑、化工建設(shè)等設(shè)施的施工作業(yè)。
2. The electric constant torque wrench can be tightened initially and finally. Its use is to adjust the torque first and then tighten the bolts. Electric angle wrench mainly belongs to a kind of constant torque wrench. Its use is to adjust the rotation degree first, and then tighten the bolt. The electric angle wrench is an electric wrench specially used to fasten the bolts at the included angle of the steel frame. Its use principle is the same as that of the electric torsion shear wrench. The electric torsional shear wrench has a large torque for disassembly and assembly, which is safer and more reliable than manual. Convenient, beautiful, practical and easy to carry with the car. It is widely used in the construction of steel structure bridges, factories, high-rise buildings, chemical construction and other facilities.
