Torsional shear bolt electric wrench with automatic torque control function is a mechanized construction tool for assembling threaded parts and bolts. This torsional shear bolt electric wrench is used for the erection of bolted and welded bridges, and the installation of plants, towers and chemical, metallurgical and power generation equipment. This type of electric wrench for torsional shear bolts is also used in the assembly of large machinery, lifting equipment and vehicles, as well as the occasions where there are strict requirements on the torque and axial tension of threaded fasteners.
扭剪型螺栓電動(dòng)扳手扭矩的選擇與調(diào)節(jié)
Selection and Adjustment of Torque of Electric Wrench for Torsion Shear Bolts
1、用戶(hù)可在1000-2500Nm的范圍內(nèi)任意選擇相應(yīng)規(guī)格的扭剪型螺栓電動(dòng)扳手。
1. The user can choose the electric wrench with the corresponding specifications for the torsional shear type bolts within the range of 1000-2500Nm.
2、控制儀面板上有“扭矩調(diào)解旋鈕”。刻有0-10個(gè)刻度值。細(xì)調(diào)旋鈕的作用是在粗調(diào)兩檔之間進(jìn)行調(diào)節(jié)補(bǔ)償，以扭矩控制精度。
2. There is a "torque adjustment knob" on the control instrument panel. It is engraved with 0-10 scale values. The fine adjustment knob is used to adjust and compensate between the two coarse adjustment gears, so as to control the accuracy with torque.
3、調(diào)節(jié)方法：國(guó)產(chǎn)品出廠時(shí)帶有扭矩測(cè)試數(shù)據(jù)卡片，供用戶(hù)標(biāo)定時(shí)參考，用戶(hù)可根據(jù)所需扭矩選擇某一刻度值，按擰緊螺栓的操作方法，擰緊螺栓，用測(cè)力扳手或其它測(cè)力儀器測(cè)出螺栓的實(shí)際扭矩值，若扭矩相差較小，可用細(xì)調(diào)加以補(bǔ)償，若相差較大，可將粗調(diào)向上或向下調(diào)一檔，反復(fù)幾次即可獲得所需扭矩值。
3. Adjustment method: Chinese products are provided with torque test data cards when leaving the factory for reference when users calibrate. Users can select a scale value according to the required torque, tighten the bolts according to the operation method of tightening the bolts, and measure the actual torque value of the bolts with a force measuring wrench or other force measuring instruments. If the torque difference is small, fine adjustment can be used to compensate. If the difference is large, coarse adjustment can be made up or down one gear, Repeat several times to obtain the required torque value.
扭剪型螺栓電動(dòng)扳手螺栓的擰緊操作
Torsional shear type bolt Tightening operation of 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(xiāo)孔與反力支架孔相對(duì)應(yīng)，然后裝入扳手套筒，插上銷(xiāo)釘，并用橡膠圈固定。
1. Install the reaction support and tighten the screws. Start the host machine to make the square head pin hole correspond to the counter force 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 positive and negative switches of the host to the forward rotation 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 reaction support arm is firmly against the support (the fulcrum can be an adjacent bolt or other positions that can be used as fulcrums), the bolt starts to tighten. When the bolt torque reaches the predetermined torque, the wrench will stop automatically. After tightening, 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 support arm will automatically disengage from the fulcrum by the elastic deformation force of the reaction support, and the wrench will be removed. If the lever arm cannot be separated from the fulcrum, the positive and negative switches can be toggled, and the power switch wrench can be inched to remove it.
