旋转式弯管工具结构简单,使用方便,装卸迅速,能减轻劳动强度,工效提高2～3倍,可用来弯制不同规格管子的工具。该工具结构如图所示。当弯制管子时,首先将丝杆3和螺帽4调节到适当位置。管子夹紧在型轮1和压块2之间,操纵手柄6使管子夹紧或松开。旋转夹紧11,可以弯制各种角度。弯 Rotary pipe bending tool has the advantages of simple structure, convenient use, rapid loading and unloading, labor intensity reduction, improved work efficiency by 2 to 3 times, and utility for bending tools of different specifications. The tool structure as shown. When bending pipe, first screw 3 and nut 4 adjusted to the appropriate position. The tube is clamped between the wheel 1 and the pressure piece 2 and the handle 6 is used to clamp or release the tube. Rotating clamp 11, you can bend a variety of angles. bend
