扭剪扭矩型電動(dòng)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(jiàn)。終緊扭剪型高強(qiáng)螺栓必須用扭剪型電動(dòng)扳手，因?yàn)榕ぜ粜透邚?qiáng)螺栓的終緊必須要把它的梅花頭打斷，只有扭剪型電動(dòng)扳手才能。現(xiàn)在高強(qiáng)螺栓的分類分為大六角高強(qiáng)螺栓和扭剪型高強(qiáng)螺栓，每種高強(qiáng)螺栓的緊固都必須先初緊再終緊。
Torsional shear torque type electric wrench is a tool for final tightening torsional shear type high-strength bolts. Generally, there are electric torsional shear wrench and manual torsional shear wrench, among which electric torsional shear wrench is more common. The final tightening of torsional shear high-strength bolt must use torsional shear electric wrench, because the final tightening of torsional shear high-strength bolt must break its plum blossom head, and only torsional shear electric wrench can. At present, high-strength bolts are classified into large hexagon high-strength bolts and torsional shear high-strength bolts. Each high-strength bolt must be tightened first and then finally.
高強(qiáng)螺栓的緊固都必須先初緊再終緊，扭剪型高強(qiáng)螺栓的初緊可以選擇沖擊電動(dòng)扳手、定扭矩電動(dòng)扳手或扭剪型電動(dòng)初緊扳手，并且一般達(dá)到終緊扭矩的50-60%就可以了。
The tightening of high-strength bolts must be initial tightening before final tightening. The initial tightening of torsional shear high-strength bolts can choose impact electric wrench, constant torque electric wrench or torsional shear electric initial tightening wrench, and generally it can reach 50-60% of the final tightening torque.
