Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a thin-diameter and thin-walled metal pipe bending device. Background Art

[0002] A bending machine refers to a device for bending pipes. It can bend straight pipes into a certain bending angle to meet actual installation requirements. Radiator tubes are generally thin-diameter, thin-walled metal pipes. According to different uses, they are bent into different angles and placed in different shapes. Bending increases the contact surface area without changing the outer diameter. Regularly arranged bends can also increase the flow speed and direction of the cooling oil. It is a good method for making radiator tubes.

[0003] After consulting the literature, it is learned that the existing patent (publication number: CN215879372U) discloses an automatic bending and clamping device for the production and processing of metal pipes, including a rectangular fixed plate, a plurality of rectangular supporting legs are fixed to the lower end of the rectangular fixed plate, a fixed bending rod is fixed to the upper end of the rectangular fixed plate, and a bending adjustment mechanism is installed at the lower part of the rectangular fixed plate, and the bending adjustment mechanism is used to adapt to different metal pipes.

[0004] Although the above-mentioned prior art can effectively fix the metal pipe, avoid the movement of the metal pipe during the bending operation, and reduce safety hazards, but when it is necessary to bend the pipe at multiple locations, the above-mentioned prior art needs to first cancel the fixation of the pipe, and then the staff manually moves the pipe to the front side, and then fix the pipe for the second time, and then the other part of the pipe groove can be bent. The operation process is very cumbersome and requires a lot of time for the staff. It has certain limitations in actual use and is of low practicality. In view of this, we propose a thin-diameter thin-walled metal pipe bending device to solve the above problems. Utility Model Content

[0026] See also Figure 1-Figure 5The utility model provides a technical solution: a thin-diameter thin-walled metal pipe bending device, including a workbench 1, a movable horizontal plate 2 is arranged on the upper surface of the workbench 1, a first guide groove 3 is opened on the upper surface of the movable horizontal plate 2, a bidirectional threaded rod 4 is rotatably connected inside the first guide groove 3, a first motor 5 is fixedly connected to the outer surface of the movable horizontal plate 2, an output shaft of the first motor 5 rotates and penetrates into the interior of the movable horizontal plate 2, the output shaft of the first motor 5 is fixedly connected to the bidirectional threaded rod 4, two opposite threads of the bidirectional threaded rod 4 are threadedly sleeved with a first guide block 6, the first guide block 6 is slidably connected to the first guide groove 3, and a vertical plate is fixedly connected to the upper surface of the first guide block 6 7, three connecting blocks 8 are fixedly connected to the opposite side surfaces of the two vertical plates 7, and clamping rings 9 are arranged on the opposite side surfaces of the connecting blocks 8 on both sides. A second guide groove 10 is opened on the upper surface of the workbench 1, and a threaded rod 11 is rotatably connected inside the second guide groove 10. A second guide block 12 is threadedly sleeved on the outer surface of the threaded rod 11, and the second guide block 12 is slidably connected to the inside of the second guide groove 10. The upper surface of the second guide block 12 is fixedly connected to the lower surface of the movable horizontal plate 2, and a second motor 13 is fixedly connected to the rear side surface of the workbench 1, and the output shaft of the second motor 13 rotates and penetrates into the interior of the workbench 1 and is fixedly connected to the threaded rod 11. By the staff The first motor 5 is started to drive the rotation of the bidirectional threaded rod 4, and the rotation of the bidirectional threaded rod 4 drives the movement of the two first guide blocks 6, and the movement of the two first guide blocks 6 drives the movement of the two vertical plates 7, and the movement of the two vertical plates 7 drives the movement of the connecting block 8, and the movement of the clamping ring 9 drives the movement of the connecting block 8, so as to finally achieve the clamping of multiple pipes at the same time. When the subsequent staff needs to bend the pipes at multiple locations, the second motor 13 is started to drive the rotation of the threaded rod 11, and the rotation of the threaded rod 11 drives the second guide block 12 to slide inside the second guide groove 10, and the movement of the second guide block 12 drives the movement of the movable cross plate 2, and the movable cross plate 2 drives the movement of the movable cross plate 2. The movement of the movable horizontal plate 2 drives the movement of the two vertical plates 7, and finally the clamping ring 9 drives the movement of the pipe, which is convenient for subsequent bending of multiple places of the same pipe. The above structure solves the problem that some existing metal pipe bending devices are not convenient for bending different places of the same pipe, further improves the practicality of the device, reduces the operating steps of the staff, and does not require the staff to fix it twice when multiple bending processes are required, thereby reducing the workload of the staff, thereby improving the efficiency of the staff in bending the pipe, improving the convenience of the pipe bending process, and at the same time, multiple pipes can be clamped and bent, which also improves the processing efficiency of the pipe.

[0027] Furthermore, a docking groove 14 extending outward is provided inside the connecting block 8, and a docking block 15 is fixedly connected to the surface of one side of the clamping ring 9 facing the connecting block 8. The docking block 15 and the docking groove 14 are slidably connected. A sliding groove 16 is provided on the inner wall of the docking groove 14. A clamping block 17 is slidably connected inside the sliding groove 16. The shape of the clamping block 17 is a trapezoid. A clamping groove 18 is provided on the outer surface of the docking block 15. The clamping block 17 and the clamping groove 18 are adapted.

A spring 20 is fixedly connected between the pull rod 19 and the outer surface of the connecting block 8. The spring 20 is sleeved on the outside of the pull rod 19.

The movable groove 16 slides inside, so that the block 17 is separated from the inside of the groove 18. The subsequent staff can take out the clamping ring 9, which is convenient for the subsequent replacement of the clamping ring 9. When the clamping ring 9 is installed, the docking block 15 slides into the inside of the docking groove 14. At this time, the docking block 15 will contact the inclined surface of the block 17. The clamping ring 9 is subsequently pushed continuously, and the docking block 15 will push the block 17. The spring 20 is stretched at this time. When the block 17 is located outside the groove 18, the elastic force of the spring 20 itself will make the block 17 stuck in the inside of the groove 18, and finally the clamping ring 9 is replaced. The above structure improves the flexibility of the device, makes it convenient for the staff to replace the clamping ring 9, so as to adapt to metal pipes of different specifications, and has high disassembly and assembly efficiency and simple operation.

[0028] Furthermore, a rotating groove 21 is opened on the upper surface of the workbench 1, and a rotating block 22 is rotatably connected inside the rotating groove 21. Two bending rods 23 are fixedly connected to the upper surface of the rotating block 22. A third motor 24 is fixedly connected to the lower surface of the workbench 1. The output shaft of the third motor 24 rotates and penetrates into the interior of the workbench 1 and is fixedly connected to the rotating block 22. The staff starts the third motor 24 to drive the rotating block 22 to rotate inside the rotating groove 21, thereby driving the bending rod 23 to rotate, thereby realizing the bending processing of the pipe.

[0029] Working principle:

[0030] When the thin-diameter thin-walled metal pipe bending device is in use, the staff starts the first motor 5 to drive the rotation of the bidirectional threaded rod 4, and the rotation of the bidirectional threaded rod 4 drives the movement of the two first guide blocks 6, and the movement of the two first guide blocks 6 drives the movement of the two vertical plates 7, and the movement of the two vertical plates 7 drives the movement of the connecting block 8, and the movement of the connecting block 8 drives the movement of the clamping ring 9, so as to finally realize the clamping of multiple pipes at the same time. When the staff needs to bend the pipe at multiple locations, the second motor 13 is started to drive the rotation of the threaded rod 11, and the rotation of the threaded rod 11 drives the second guide block 12 to slide inside the second guide groove 10, and the movement of the second guide block 12 drives the movement of the movable cross plate 2, and the movement of the movable cross plate 2 drives the movement of the two vertical plates 7, so as to finally realize the movement of the pipe driven by the clamping ring 9, so as to facilitate the subsequent bending of multiple locations of the same pipe.
