Maintenance and management of electric torsional shear wrench:

由于電動(dòng)扭剪扳手是高頻應(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)管理的真實(shí)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。

As the electric torsional shear wrench is a high-frequency application tool, in order to improve the measurement accuracy, it is necessary to calibrate and check the tool regularly, and configure the electric torsional shear wrench equipment that meets the use requirements. At present, the electric torsional shear wrench is mainly calibrated by the calibrator, and the calibrator needs to be checked regularly. Since the calibration environment is a laboratory environment, it is very different from the field operation environment. In order to ensure the authenticity of calibration management, it is necessary to refer to the actual use site for management, and the error is not affected by the use occasion.

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。

Before use, pay attention to check the accuracy of the electric torsion shear wrench, and adjust the calibration and maintenance frequency according to the use frequency. Usually at least once a year, use maintenance and management means to ensure the accuracy of electric torsion shear wrench.

電動(dòng)扭剪扳手的正確使用方法：

Correct use of electric torsional shear wrench:

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，可以感覺到手部振動(dòng)或聽到“喀噠”聲，即扭矩已完成。

Electric torque shear wrench is mainly used to install fasteners, such as bolts, screws and nuts. Through torque control, the tightening of the thread is ensured, and the thread will not be damaged due to excessive torque. Therefore, it is necessary to use the electric torsion shear wrench to fix the torque value, and the fixed torque value needs to be set in advance in the application process. When the set value is reached, the electric torsional shear wrench will send out a reminder message. You can feel the hand vibration or hear the "click" sound, that is, the torque has been completed.

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）。

When the torque value reaches the fixed position, there is no need to continue to apply force. Do not use impact force. After the force is stopped, all parts will be reset. When applying torque, hold your hand on the middle scale line of the handle of the electric torsion shear wrench, and apply force only in the direction indicated by the electric torsion shear wrench. At the same time, the force application direction shall be within ± 15 ° (vertical direction and horizontal direction).

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。

According to the strength and torque of fasteners, a wrench with appropriate range shall be used, and it is not allowed to exceed the application range of the wrench. The wrench needs to be zeroed before use. When there is no load, pay attention to the inspection of the pointer of the torque wrench to see whether the pointer is on the zero scale value. If not, it needs to be adjusted. In order to ensure accurate reading, hold the handle of the wrench with one hand during use, keep the torque wrench at right angles to the tension, and apply force stably.

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)旋鈕將指針返回到零位，以便進(jìn)行下一個(gè)應(yīng)用。 作為測(cè)量工具，需要注意保護(hù)電動(dòng)扭剪扳手。禁止進(jìn)行扔擲、震動(dòng)以及敲擊等。

When the pointer points to the torque value, do not use too much force, otherwise the error value will appear. After the measurement is completed, rotate the knob to return the pointer to the zero position for the next application. As a measuring tool, it is necessary to protect the electric torsion shear wrench. Throwing, shaking and knocking are prohibited.
