扭剪電動(dòng)扭力扳手的維護(hù)：

Maintenance of electric torque wrench for torsion shear:

由于扭剪電動(dòng)扭力扳手是高頻應(yīng)用工具，為了提高測(cè)量精度，有必要定期校準(zhǔn)和檢查工具，并配置滿足使用要求的電動(dòng)扭剪扳手設(shè)備目前，電動(dòng)扭剪扳手主要由檢定儀對(duì)電動(dòng)扭剪扳手進(jìn)行校準(zhǔn)，檢定儀需要定期檢查由于校準(zhǔn)環(huán)境是試驗(yàn)室環(huán)境，因此與現(xiàn)場(chǎng)操作環(huán)境有很大的不同為了確保校準(zhǔn)管理的有效性，有必要參考實(shí)際使用現(xiàn)場(chǎng)進(jìn)行管理，并且要求誤差不受使用場(chǎng)合的影響使用前要注意檢查電動(dòng)扭剪扳手的準(zhǔn)確性，并根據(jù)使用頻率調(diào)整校準(zhǔn)和維護(hù)的頻率通常每年不少于一次，利用維護(hù)管理手段保證電動(dòng)扭剪扳手的準(zhǔn)確性

Due to the high-frequency application of electric torque wrenches, it is necessary to regularly calibrate and inspect the tools in order to improve measurement accuracy, and equip them with electric torque wrench equipment that meets usage requirements. Currently, electric torque wrenches are mainly calibrated by calibration instruments, which need to be checked regularly. As the calibration environment is a laboratory environment, Therefore, there is a significant difference from the on-site operating environment. In order to ensure the effectiveness of calibration management, it is necessary to refer to the actual usage site for management, and it is required that errors are not affected by the usage situation. Before use, attention should be paid to checking the accuracy of the electric torque wrench, and the calibration and maintenance frequency should be adjusted according to the frequency of use. Generally, the frequency of calibration and maintenance should not be less than once a year. Maintenance management methods should be used to ensure the accuracy of the electric torque wrench

扭剪電動(dòng)扭力扳手的正確使用方法：

The correct usage of electric torque wrench for torsion shear:

電動(dòng)扭剪扳手主要用于安裝緊固件，例如螺栓，螺釘和螺母通過(guò)扭矩控制，確保了螺紋的擰緊，并且不會(huì)因扭矩過(guò)大而損壞螺紋因此，有必要使用電動(dòng)扭剪扳手進(jìn)行扭矩值固定操作，在施加過(guò)程中需要預(yù)先設(shè)置固定扭矩值當(dāng)達(dá)到設(shè)定值時(shí)，電動(dòng)扭剪扳手將發(fā)出提醒信息，可以感覺(jué)到手部振動(dòng)或聽(tīng)到喀噠聲，即扭矩已完成。 當(dāng)扭矩值達(dá)到固定位置時(shí)，無(wú)需繼續(xù)施加力。 請(qǐng)勿使用沖擊力，停止施加力后，各個(gè)零件復(fù)位。 施加扭矩時(shí)，將手握在電動(dòng)扭剪扳手手柄的中間刻度線上，并僅在電動(dòng)扭剪扳手指示的方向上施加力，同時(shí)施力方向應(yīng)在±15°以內(nèi)（垂直方向和水平方向）。

Electric torque wrench is mainly used for installing fasteners, such as bolts, screws, and nuts. Through torque control, it ensures the tightening of threads and does not damage them due to excessive torque. Therefore, it is necessary to use an electric torque wrench for torque value fixing operation. During the application process, the fixed torque value needs to be pre-set. When the set value is reached, the electric torque wrench will send a reminder message, You can feel hand vibration or hear a clicking sound, indicating that the torque has been completed. When the torque value reaches a fixed position, there is no need to continue applying force. Do not use impact force. After stopping the application of force, all parts should be reset. When applying torque, hold your hand on the middle scale line of the electric torque wrench handle and apply force only in the direction indicated by the electric torque wrench, while the direction of application should be within± 15° Within (vertical and horizontal directions).

根據(jù)緊固件的強(qiáng)度和扭矩用以使用合適量程的扳手，并且不允許超過(guò)扳手的適用范圍。扳手在使用前需要調(diào)零，無(wú)荷載時(shí)注意對(duì)扭矩扳手指針的檢查，看指針是否在零標(biāo)度值上，如果不是則需要對(duì)其進(jìn)行調(diào)整為確保讀數(shù)準(zhǔn)確，在使用過(guò)程中需要用一只手握住扳手的手柄，使扭矩扳手和拉力保持直角，并穩(wěn)定地施加力當(dāng)指針指向扭矩值時(shí)，禁止用力過(guò)大，否則會(huì)出現(xiàn)誤差值測(cè)量完成后，旋轉(zhuǎn)旋鈕將指針?lè)祷氐搅阄?，以便進(jìn)行下一個(gè)應(yīng)用作為測(cè)量工具，必須注意保護(hù)電動(dòng)扭剪扳手。禁止進(jìn)行扔擲、震動(dòng)以及敲擊等

Use a wrench with an appropriate range based on the strength and torque of the fastener, and do not exceed the applicable range of the wrench. The wrench needs to be zeroed before use. When there is no load, pay attention to checking the torque wrench pointer to see if it is on the zero scale value. If it is not, adjust it to ensure accurate reading. During use, hold the handle of the wrench with one hand to maintain a right angle between the torque wrench and the pulling force, and apply force steadily. When the pointer points to the torque value, do not use too much force, otherwise errors may occur. After the measurement is completed, Rotate the knob to return the pointer to the zero position for the next application. As a measuring tool, attention must be paid to protecting the electric torsion wrench. Throwing, shaking, and striking are prohibited
