Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe bending processing, in particular to a bending device for sanitary ware metal pipes. Background Technique

[0002] Metal pipes are generally classified by materials, including copper pipes, iron pipes, steel pipes, aluminum alloy pipes, etc., and are mainly used as drainage pipes and conveying pipes in buildings. Therefore, in daily life, metal pipes are generally used for the assembly of frames, such as display racks, sanitary ware brackets, etc. When used for frame assembly, due to the shape of the frame and assembly requirements, the metal pipes often need to be bent so that the metal pipes are arc-shaped to meet different installation requirements.

[0003] The existing bending devices use pipe benders for pipe bending processing. And some of the existing pipe benders use cylinders as power for bending processing, that is, the metal pipe is first limited and fixed, and then the bending head is driven by the cylinder to move towards the metal pipe to bend the metal pipe, or a stamping structure is used to realize the bending of the bent pipe, that is, the metal pipe is placed at the groove for stamping and bending.

[0004] This structure will result in limited bending angles, a single bending angle, and the lack of a cutting device will affect the bending accuracy, thereby leading to poor applicability and practicability of the device. And when this pipe bender is processing, since only the bending head moves unidirectionally, this processing method reduces the production efficiency, so it needs to be improved. Content of the Utility Model

[0007] Further, the auxiliary component includes a second connecting rod. A second connecting rod is rotatably connected to the outer wall of the first rotating shaft.
