扭剪型高強度螺栓屬于自標量型螺栓，其施工緊固扭矩是由螺桿與螺栓尾部梅花頭之間的切口直徑?jīng)Q定，即靠其扭斷力矩來控制，施工時要采用扭剪型電動扳手，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。
Twist shear high-strength bolts belong to self scalar bolts, and their construction tightening torque is determined by the diameter of the incision between the screw and the end of the bolt's plum blossom head, which is controlled by its torque. During construction, a torsion shear electric wrench should be used, which is simple to use by aligning the bolt and turning the power switch. The electric torque wrench is mainly used for final tightening torque shear high-strength bolts. Its use is to align the bolt and pull the power switch until the plum blossom head of the torque shear high-strength bolt is broken.
該電動扳手配有內(nèi)外兩個套管，外套筒扭螺母，對螺栓施加扭矩，內(nèi)套筒反向扭梅花頭，兩個扭矩大小相等，方向相反，尾部梅花頭擰掉，讀出預拉力值。扭剪型高強度螺栓更具有施工方便，檢查直觀，受力良好，保障質(zhì)量等優(yōu)點，在高層鋼結構工程上大部分都采用這種形式。
This electric wrench is equipped with two inner and outer sleeves. The outer sleeve twists the nut to apply torque to the bolt, and the inner sleeve twists the plum blossom head in the opposite direction. The two torques are equal in magnitude and opposite in direction, and the plum blossom head is unscrewed at the tail end to read the pre tension value. Twist shear high-strength bolts have the advantages of convenient construction, intuitive inspection, good stress, and quality assurance. They are mostly used in high-rise steel structure engineering.
數(shù)顯扭矩扳手和機械式扭力扳手主要的差異在于數(shù)顯示扭矩扳手有其精準度與穩(wěn)定度，這是機械式扭力扳手所望塵莫及的。
The main difference between digital torque wrenches and mechanical torque wrenches lies in their precision and stability, which are unmatched by mechanical torque wrenches.
數(shù)顯示扭矩扳手的準確度0.5%~3%，機械式扭力扳手為3%~6%。
The accuracy of the numerical display torque wrench is 0.5%~3%, while that of the mechanical torque wrench is 3%~6%.
其另外一個差異在于警報的方式不同。機械式扭力扳手皆由彈性機械結構的跳脫或是打滑方式來警報使用者已達到目標扭力。而數(shù)顯示扭力扳手的警報方式則比較多元，主要有：震動裝置、燈光提示、聲音提醒、數(shù)字顯示等方式。
Another difference lies in the way the alarm is triggered. Mechanical torque wrenches are alerted to the user that the target torque has been reached by the elastic mechanical structure's jumping or slipping method. The alarm methods for torque wrenches with numerical display are relatively diverse, mainly including vibration devices, light prompts, sound prompts, digital displays, and other methods.
震動裝置：當達到目標扭力時，扭矩扳手內(nèi)的震動馬達會開始震動，而震動的觸感會讓使用者反射性動作地將手從手柄上放開，已達到停止施力的目的。在吵雜的作業(yè)環(huán)境中，震動裝置警報效果更好。
Vibration device: When the target torque is reached, the vibration motor inside the torque wrench will start to vibrate, and the tactile sensation of the vibration will cause the user to reflexively release their hand from the handle, achieving the goal of stopping the force application. In noisy work environments, vibration devices have better alarm effects.
燈光提示：在使用扭力扳手時，LED會依照當前產(chǎn)生的扭力值與目標扭力值的差距，產(chǎn)生不同頻率快慢閃爍;當達到目標扭力時，警示燈會持續(xù)亮起。當使用者看到時，停止施力，此時螺絲已精準達到目標扭力。在明亮度較差的作業(yè)環(huán)境時，燈光提示效果則為明顯。
Light prompt: When using a torque wrench, the LED will flash at different frequencies based on the difference between the current torque value and the target torque value; When the target torque is reached, the warning light will continue to light up. When the user sees it, stop applying force, and the screw has accurately reached the target torque. When working in environments with poor brightness, the lighting prompt effect is more pronounced.
聲音提醒：在使用扭力扳手時，蜂鳴器會依照當前產(chǎn)生的扭力值與目標扭力值的差距，產(chǎn)生不同頻率發(fā)出嗶鳴聲若當前產(chǎn)生的扭力值越靠近目標扭力值，蜂鳴器的嗶 鳴聲頻率會越快速，當達到目標扭力時，蜂鳴器會持續(xù)發(fā)出長嗶鳴聲。使用者可以依照聲音頻率來控制施加扭力的程度;當使用者聽到長嗶鳴聲時，停止施力，此時螺絲已精準達到目標扭力。在一般環(huán)境下，聲音提醒是為有效率的一種方式。
Sound reminder: When using a torque wrench, the buzzer will emit a beep at different frequencies based on the difference between the current torque value and the target torque value. If the current torque value is closer to the target torque value, the beep frequency of the buzzer will be faster. When the target torque is reached, the buzzer will continue to emit a long beep sound. Users can control the degree of torque application based on sound frequency; When the user hears a long beep, stop applying force, and the screw has accurately reached the target torque. In general environments, sound reminders are an efficient way.
數(shù)字顯示：在使用扭力扳手時，LCD顯示屏會顯示當下所產(chǎn)生的扭力;施加越大的力量，數(shù)字則會逐漸增加。眼睛直視著LCD顯示屏上的數(shù)字變化，可以更精準地控制欲產(chǎn)生的扭力，并將誤差的程度降到低處。此方式特別適合執(zhí)行于要求高精度、高品質(zhì)的組裝修繕作業(yè)。
Digital display: When using a torque wrench, the LCD display screen will display the current torque generated; The greater the force applied, the more the number will gradually increase. Gazing directly at the digital changes on the LCD screen allows for more precise control of the desired torque and reduces the degree of error. This method is particularly suitable for performing group decoration and repair operations that require high precision and quality.
