This machine is the second generation of DH-DG1 General Electric Pipe Bender. Compared with the first generation DH-DG1 bender, the space length of the two driving shafts of the machine is adjustable, thereafter we can bend various diameter parts: round tube, square tube, rectangular tube, as well as large and small diameter arc and round products. Owing to the adjustable transverse distance of the two shafts, it can process thick and large pipes easily. In operation we can get arc and round parts with different diameters by controlling the press-down sizes of the driven roller. The machine has large processing ability, and can be used extensively and laborsaving. There are 9 kinds of dies as the machine attachments, including 8 sets of square tube dies: 15?5mm, 20?0mm, 25?5mm, 30?0mm, 40?0mm, 50?0mm, 60?0mm, 70?0mm,above dies can be used to bend rectangular tube, as well as 1 set of straight flat iron bending dies. In addition, there are 9 sets of round tube dies for selection: φ16mm, φ19mm, φ22mm, φ24mm, φ30mm, φ36mm, φ50mm, φ63mm, and φ76mm.
