DETAILED DESCRIPTION

[0037] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0038] In the following description, "left", "right", "front", "back", "up", "down" are oriented in the perspective direction of the front view.

[0039] Embodiment one: in some embodiments, referring to the drawings of the specification Figures 1-5 A magnetic suspension pipe bending machine with good pipe bending effect, comprising a pipe feeding assembly 1, a constant temperature heating mechanism 2, a heat preservation sleeve 3, a concentric material guiding mechanism 4, an adjustable bending mechanism 5, a slitting module 6 and a cooling module 7.

[0040] The pipe feeding assembly 1, the constant temperature heating mechanism 2 and the adjustable bending mechanism 5 are sequentially arranged from right to left; the pipe feeding assembly 1 comprises a feeding module 11, a feeding module 12 and a moving module 13, the feeding module 11, the moving module 13 and the feeding module 12 are sequentially arranged from right to left, the moving module 13 is installed on the feeding module 11, and the moving end of the moving module 13 is installed with a magnetic suspension material guiding support module 14 for supporting the bent part of the pipe;

[0041] The heat preservation sleeve 3 with built-in heat preservation electric heating wire is fixedly installed between the left side of the constant temperature heating mechanism 2 and the adjustable bending mechanism 5; the concentric material guiding mechanism 4 for assisting the conveying of the pipe is installed in the constant temperature heating mechanism 2 and the heat preservation sleeve 3; the slitting module 6 for cutting the pipe is installed on the adjustable bending mechanism 5, and the cooling module 7 for accelerating the cooling of the bent pipe is installed on the adjustable bending mechanism 5.

[0042] In this embodiment, when the magnetic levitation pipe bending machine with good bending effect is working normally, the pipe to be processed passes through the feeding module 11, the feeding module 12, and the magnetic levitation guiding support module 14 in sequence, and then passes through the concentric guiding mechanism 4 inside the constant temperature heating mechanism 2 and the insulation sleeve 3, so that the end of the pipe to be processed is located at the adjustable bending mechanism 5. During the bending process, the pipe moves to the left through the cooperation of the feeding module 12 and the adjustable bending mechanism 5. The constant temperature heating mechanism 2 heats the pipe at a constant temperature to facilitate subsequent bending. After the pipe is heated, it passes through the insulation sleeve 3 to reach the bending part. During this process, the concentric guiding mechanism 4 inside the constant temperature heating mechanism 2 and the insulation sleeve 3 assists in the pipe transfer, realizing the guiding of the pipe and avoiding scratches on the pipe during heating and transfer. At the same time, the concentric guiding mechanism 4 cleans the dust on the outside of the pipe. After the pipe passes through the concentric guiding mechanism 4, the adjustable bending mechanism 5 bends the pipe. After bending, the cooling module 7 accelerates the cooling of the pipe, allowing it to quickly set and ensuring bending quality while improving efficiency. Simultaneously, during bending, the magnetic levitation material guide support module 14 on the moving module 13 supports the section of the pipe to be bent, ensuring the pipe remains circular during the bending process and preventing deformation. This guarantees bending quality. After bending, the moving module 13 moves the magnetic levitation material guide support module 14 to the right, detaching it from the bent pipe. The cutting module 6 then cuts the pipe. After cutting, the adjustable bending mechanism 5 and the feeding module 12 continue to transport the pipe to the left. Simultaneously, the moving module 13 resets the magnetic levitation material guide support module 14, allowing it to move back to the bending position with the pipe, maintaining support for the bent section. This enables continuous bending and cutting of the pipe.
