[0017] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0018] For example, Figure 4As shown in the utility model provides a kind of loop forming tool, including roof 1, bottom plate 2, movable plate 3, support assembly 4, bending assembly 5, hydraulic cylinder 6 and adjusting positioning assembly 7, wherein the four corners of roof are fixed on bottom plate with cooperation of multiple groups of guide rod 8, and movable plate is fitted with guide sleeve 9 on guide rod, hydraulic cylinder is fixed above roof, and its telescopic end is connected with movable plate through roof, control movable plate moves up and down along guide column, the bending assembly is fixed on the back of movable plate, support assembly is fixed on the surface of floor and is oppositely arranged with bending assembly, adjusting positioning assembly is located at the side of support assembly, and the pipe placed on support assembly is positioned on side, and hydraulic cylinder controls bending assembly to press pipe to realize bending processing when moving down.
[0019] Specifically, the support assembly includes two groups of support seats 41 arranged symmetrically, and has a forming gap 42 between the two groups of support seats, the support seat surface is embedded with a bearing roller 43, and the bearing roller surface has a U-shaped groove 44, the pipe placed in the U-shaped groove can avoid rolling.
