[0002] Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in various environments, such as outdoors, underwater, and in space. Regardless of the location, welding can pose dangers to operators, so appropriate protective measures must be taken. Potential injuries from welding include burns, electric shock, vision impairment, inhalation of toxic fumes, and excessive ultraviolet radiation. Welded pipe is a specialized term in the construction industry, serving various purposes on construction sites. It facilitates the finishing and construction of areas inaccessible due to height, provides safety netting for construction workers and pedestrians, and is used for high-altitude installations.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1:

[0024] Reference Figure 1-4 A bending device for welded pipe processing includes a workbench 1, a central column 2 welded at the center of the workbench 1, and a shaft hole 3 opened at the center of the central column 2. A bending structure 4 is rotatably connected in the shaft hole 3, and an auxiliary component 5 is provided on the outer wall of the central column 2. A parallel plate 6 is welded to one end of the top outer wall of the workbench 1, and a support component 7 is provided on the workbench 1 at the parallel plate 6.

[0025] The bending structure 4 includes a rotating shaft 8, an extension rod 9 welded to the outer wall of the top end of the rotating shaft 8, and an adjustment hole 10 opened at the center of the extension rod 9;

[0026] A threaded hole 11 is provided at the center of one end of the extension rod 9, and a threaded rod 14 is threadedly connected in the threaded hole 11. An adjustment block 12 is slidably connected to the extension rod 9 in the adjustment hole 10, and one end of the threaded rod 14 is rotatably connected to the outer wall of the adjustment block 12.

[0027] A bent rod 13 is welded to the center of the bottom outer wall of the adjusting block 12, and a drive hole 15 is opened on the outer wall of the other end of the threaded rod 14. The threaded rod 14 is driven to move in the threaded hole 11 through the drive hole 15 at one end of the threaded rod 14, which in turn drives the adjusting block 12 to move in the adjusting hole 10, so that the outer wall of the bent rod 13 contacts the outer wall of the pipe fitting, which facilitates the adjustment of the spacing.

[0028] A drive groove 16 is provided at the center of the bottom outer wall of the workbench 1, and a drive motor 18 and a reducer 17 are respectively installed in the drive groove 16. The output shaft of the drive motor 18 is connected to the input end of the reducer 17, and the output end of the reducer 17 is connected to the bottom end of the rotating shaft 8. The drive motor 18 cooperates with the reducer 17 to reduce the speed and increase the torque, so as to drive the bending rod 13 to rotate through the rotating shaft 8 and the extension rod 9, which facilitates bending.

[0029] The drive motor 18, heating wire 25, and electric push rod 22 are connected to a switch via wires, and the switch is connected to a power source via wires. After the heating wire 25 is energized and heats up, it heats the bending area of ​​the pipe fitting. Then, the drive motor 18 is started. The drive motor 18 drives the rotating shaft 8 and the extension rod 9 to rotate through the reducer 17. The bending rod 13 on the extension rod 9 exerts force on the pipe fitting, causing the heated area of ​​the pipe fitting to bend. The heating wire 25 is stopped during bending to facilitate bending and to facilitate the elimination of stress after bending.

[0030] Example 2:

[0031] Reference Figure 1-2 The support component 7 includes sliding grooves 19 that are equally spaced on the outer wall of the workbench 1 and support rods 20 that are slidably connected to the sliding grooves 19 and the outer wall of the workbench 1. It restricts the pipe between the parallel plate 6 and the support rods 20, and supports and restricts the non-bending end of the pipe, which is convenient for restricting one end of the pipe and for bending.

[0032] Mounting bases 21 are installed on the top outer wall of the workbench 1 between the sliding grooves 19, and electric push rods 22 are installed on the inner wall of the mounting bases 21.

[0033] Anti-slip pads 23 are glued to the outer wall of the support rod 20 and the parallel plate 6 on the side that are close to each other. One end of the electric push rod 22 is installed on the outer wall of the support rod 20. When the electric push rod 22 on the mounting base 21 is activated, it pushes the support rod 20 closer to the parallel plate 6. The anti-slip pads 23 restrict the pipe fitting inside, ensuring the verticality of one end of the pipe fitting and facilitating bending.

[0034] The auxiliary component 5 includes heating grooves 24 evenly spaced on the outer wall of the central column 2 and heating wires 25 installed in the heating grooves 24. The heating wires 25 on the central column 2 preheat the bending area of ​​the pipe fitting, which facilitates bending, reduces stress after bending, prevents the pipe fitting from springing back after bending, and improves the accuracy of the bending angle.

[0035] Working principle: During use, the pipe to be bent is placed on the workbench 1, positioned between the bending rod 13 and the central column 2, and between the support rod 20 and the parallel plate 6. Adjusting the bending position of the pipe activates the electric push rod 22, which moves the support rod 20 across the workbench 1 and the sliding groove 19, confining the pipe between the parallel plate 6 and the support rod 20. This supports and restricts the non-bending end of the pipe, facilitating bending. The threaded rod 14 moves through the drive hole 15 at one end of the threaded rod 14 within the threaded hole 11, thus... The adjusting block 12 moves in the adjusting hole 10, so that the outer wall of the bending rod 13 contacts the outer wall of the pipe. The heating wire 25 of the heating groove on the central column 2 is activated. After the heating wire 25 is energized and heated, it heats the bending area of ​​the pipe. Then the drive motor 18 is activated. The drive motor 18 drives the rotating shaft 8 and the extension rod 9 to rotate through the reducer 17. The bending rod 13 on the extension rod 9 exerts force on the pipe to drive the heated area of ​​the pipe to bend. The heating wire 25 is stopped when bending, which facilitates bending, facilitates the elimination of stress after bending, and prevents the pipe from springing back after bending.
