剪型電動(dòng)扳手具有精度高（±5%）、故障率低、壽命長(zhǎng)、可編程，可對(duì)扭力和角度控制、可多種扭力選擇的優(yōu)點(diǎn)。因?yàn)閿Q大扭矩螺栓會(huì)有反作用力，所以一般在大扭矩?cái)Q緊工件上都會(huì)設(shè)計(jì)反作用力臂，防止操作人員出現(xiàn)事故。
Scissor electric wrench has the advantages of high precision (± 5%), low failure rate, long service life, programmable, torque and angle control, and multiple torque options. Because there will be reaction force when tightening high torque bolts, reaction force arms are generally designed on high torque tightening workpieces to prevent accidents for operators.
高強(qiáng)螺栓扭剪型電動(dòng)扳手采用進(jìn)口雙重絕緣串激式電動(dòng)機(jī)，體積小，重量輕，更加可靠，使用了推力載何方式，依靠?jī)?nèi)套筒的花鍵連接和定位承受負(fù)載。采用行星變速機(jī)構(gòu)，利用特殊鋼材和特殊的熱處理方法，經(jīng)久耐用。
The high-strength bolt torsion shear electric wrench adopts imported double insulation series motor, which has the advantages of small volume, light weight and more reliable. It uses the thrust load mode and bears the load by relying on the spline connection and positioning of the inner sleeve. Planetary speed change mechanism, special steel and special heat treatment method are adopted, which is durable.
高強(qiáng)螺栓扭剪型電動(dòng)扳手螺栓的擰緊操作：
Tightening operation of high-strength bolt torsion shear electric wrench bolt:
1、裝上反力支架，并緊固螺釘。開(kāi)動(dòng)主機(jī)，使方頭銷孔與反力支架孔相對(duì)應(yīng)，然后裝入扳手套筒，插上銷釘，并用橡膠圈固定。
1. Install the reaction support and tighten the screws. Start the main engine so that the square head pin hole corresponds to the reaction support hole, then install the wrench socket, insert the pin and fix it with a rubber ring.
2、將控制儀的扭矩旋鈕調(diào)到所需扭矩值，將主機(jī)正反開(kāi)關(guān)撥到正轉(zhuǎn)位置，把扳手套筒套在螺紋連接件的六方上。
2. Adjust the torque knob of the controller to the required torque value, turn the forward and reverse switch of the host to the forward position, and put the wrench socket on the hexagon of the threaded connector.
3、按下電源開(kāi)關(guān)，扳手啟動(dòng)。當(dāng)反力支架力臂靠牢支架時(shí)（支點(diǎn)可以是鄰近的一只螺栓或其他可作支點(diǎn)的位置）螺栓開(kāi)始擰緊。當(dāng)螺栓扭矩達(dá)到預(yù)定扭矩時(shí)，扳手自動(dòng)停止，緊固完成，松開(kāi)電源開(kāi)關(guān)，進(jìn)行下一只螺栓的擰緊工作。
3. Press the power switch and the wrench starts. When the force arm of the reaction support is firmly against the support (the fulcrum can be an adjacent bolt or other position that can be used as the fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop, the tightening is completed, loosen the power switch and tighten the next bolt.
4、扳手自動(dòng)停止后，靠反力支架的彈性形變力，使支架力臂自動(dòng)脫離支點(diǎn)，取下扳手。如力臂不能脫離支點(diǎn)時(shí)，可撥動(dòng)正反開(kāi)關(guān)，點(diǎn)動(dòng)電源開(kāi)關(guān)扳手即可取下。
4. After the wrench stops automatically, the elastic deformation force of the reaction support makes the support force arm automatically separate from the fulcrum and remove the wrench. If the force arm cannot be separated from the fulcrum, turn the positive and negative switch and click the power switch wrench to remove it.
