扭剪型高強螺栓安裝規(guī)定:安裝時高強螺栓應(yīng)自由穿入孔內(nèi),不得強行敲打。螺栓不能自由穿入時,不得用氣割擴孔,要用絞刀絞孔,修孔時需使板層緊貼,以防鐵屑進入板縫,絞孔后要用砂輪機孔邊毛刺,并鐵屑。
When installing the high-strength bolt in the torsion hole, it is not allowed to strike the high-strength bolt by force. When the bolt cannot be penetrated freely, it is not allowed to use gas cutting to ream the hole. It is necessary to use a cutter to ream the hole. When repairing the hole, it is necessary to make the plate layer close to each other to prevent iron chips from entering the plate seam. After reaming, it is necessary to use a grinder to remove the burr at the edge of the hole and iron chips.
初擰緊固到螺栓標(biāo)準(zhǔn)軸力(即設(shè)計預(yù)拉力)的60%~80%,初擰的扭矩值不得小于終擰扭矩值的30%。從接頭剛度大的地方向不受約束的自由端進行。
The initial tightening shall be 60% - 80% of the standard axial force (i.e. design pretension) of the bolt, and the initial tightening torque shall not be less than 30% of the final tightening torque. From the place with large joint stiffness to the free end without restraint.
電動扭剪扳手主要是終緊扭剪型高強螺栓的,它的目的是把扭剪型高強螺栓的梅花頭剪斷即可,工作時將扳手頭對準(zhǔn)螺栓頭,扣動開關(guān)即可開始工作,幾秒后,螺栓梅花頭將被扭斷,然后抽出扳手扣動扳機將梅花頭彈出,這樣就緊固好扭剪型高強螺栓了。
The electric wrench is mainly used to tighten the high-strength bolt. Its purpose is to cut the box head of the high-strength bolt. When working, align the wrench head with the bolt head and pull the switch to start working. After a few seconds, the box head of the bolt will be twisted. Then pull out the wrench and pull the trigger to eject the box head, so as to fasten the high-strength bolt.
電動扭剪扳手的特點:
Features of electric torsion wrench:
1、整機體積小、重量輕,操作方便,并且可以在狹小空間使用
1. The whole machine is small in size, light in weight, easy to operate, and can be used in a small space
2電動扭剪扳手采用德國進口電機,功率大,體積小,扭剪速度快,可明顯提高勞動效率
2. The electric torsional shear wrench adopts the motor imported from Germany, which has the advantages of large power, small volume, fast torsional shear speed, and can obviously improve the labor efficiency
3、使用壽命長,采用高品質(zhì)原材料,數(shù)道加工工序,加特有的熱處理技術(shù)及車床加工技術(shù),生產(chǎn)出的產(chǎn)品使用壽命長。
3. Long service life, using high-quality raw materials, several processing procedures, plus the unique heat treatment technology and lathe processing technology, the product has a long service life.
4、耐撞擊性強,采用原材料,堅固耐用
4. Strong impact resistance, using high-quality raw materials, durable
