[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides as Figures 1 to 4A bending device for processing truss fittings as shown, including an operating table 1. Above the operating table 1, a fixed bending mechanism is provided. The fixed bending mechanism includes a disc 2. A square tube 3 is fixedly connected to the outer ring of the disc 2. There are multiple square tubes 3, and the multiple square tubes 3 are evenly distributed around the disc 2. A sliding column 4 is slidably arranged at one end of the square tube 3 away from the disc 2. A circular arc sleeve 6 is fixedly connected to the end of the sliding column 4 away from the square tube 3. And the surface of the circular arc sleeve 6 facing the disc 2 is a concave surface. An arc bar 7 is slidably arranged between adjacent two circular arc sleeves 6. Since the sliding column 4 is slidably arranged on the square tube 3, the position of the circular arc sleeve 6 is adjustable.

[0023] A round rod 10 is fixedly connected to the bottom of the disc 2, and the bottom end of the round rod 10 is fixedly connected to the operating table 1.

[0024] When driving one of the circular arc sleeves 6 to move away from the disc 2, with the cooperation of the arc bar 7, the multiple circular arc sleeves 6 move away from the disc 2 at the same time, so that the outer diameter of the fixed bending mechanism expands, which can meet the bending of large sizes; when driving one of the circular arc sleeves 6 to move towards the disc 2, with the cooperation of the arc bar 7, the multiple circular arc sleeves 6 move towards the disc 2 at the same time, so that the outer diameter of the fixed bending mechanism shrinks, which can meet the bending of small sizes.

[0025] By setting structures such as the square tube 3, the sliding column 4 and the circular arc sleeve 6, the diameter of the fixed bending mechanism is adjustable, improving the applicability of the bending device.

[0026] To improve the stability of the fixed bending mechanism, sliding channels 8 are opened at both ends of the circular arc sleeve 6. A slider 9 is slidably connected inside the sliding channel 8, and the slider 9 is fixedly connected to the corresponding arc bar 7. When the arc bar 7 slides inside the circular arc sleeve 6, it will drive the slider 9 to slide inside the sliding channel 8.

[0027] To facilitate fixing the size of the fixed bending mechanism, a first bolt 5 for fastening the position of the sliding column 4 is threadedly connected to the side wall of one of the square tubes 3. When the size of the fixed bending mechanism needs to be adjusted, rotate the first bolt 5 to release the restriction on the sliding column 4, facilitating the control of the sliding of the sliding column 4 on the square tube 3; after the adjustment is completed, rotate the first bolt 5 in the reverse direction, and the end of the first bolt 5 presses on the sliding column 4 to limit the sliding column 4, thereby fixing the size of the fixed bending mechanism. In specific use, the first bolt 5 can also be arranged on multiple square tubes 3 to improve the fastening stability.

[0028] To improve the stability of bending, a limiting block 19 is fixedly connected to the side of the circular arc sleeve 6 facing away from the sliding column 4. There are two limiting blocks 19, and the two limiting blocks 19 are respectively distributed at the upper and lower ends of the circular arc sleeve 6, so that the pipe is limited between the two limiting blocks 19 and will not slip off. And in specific use, the protruding surface of the circular arc sleeve 6 can be set as an arc groove structure to improve the bending stability.

[0029] A rotating plate 11 is rotatably connected to a round rod 10. A sliding frame 12 is slidably connected to the rotating plate 11. A moving bending pipe wheel 14 is fixedly connected to the sliding frame 12. A holding rod 15 is fixedly connected to the top of the moving bending pipe wheel 14. A second bolt 13 is threadedly connected to the sliding frame 12. The position of the sliding frame 12 can be adjusted on the rotating plate 11, so as to adjust the position of the moving bending pipe wheel 14 to meet the adjustment of the size of the fixed bending mechanism. Specifically, when the size of the fixed bending mechanism is increased, the second bolt 13 is rotated to control the sliding frame 12 to move away from the round rod 10 on the rotating plate 11, driving the moving bending pipe wheel 14 to move synchronously, and then the second bolt 13 is rotated in the reverse direction to fix the position of the sliding frame 12.

[0030] A positioning seat 16 is slidably arranged at one end of the operating table 1 away from the fixed bending mechanism. A through groove 17 is formed in the positioning seat 16. A third bolt 18 is threadedly connected to the positioning seat 16. The position of the positioning seat 16 is fixed by the end of the third bolt 18 pressing against the operating table 1. The position of the positioning seat 16 can be adjusted according to the size of the fixed bending mechanism.

[0031] During use, the pipe is passed through the through groove 17 on the positioning seat 16. At the same time, the pipe is located between the fixed bending mechanism and the moving bending pipe wheel 14. When bending, the moving bending pipe wheel 14 is rotated uniformly through the holding rod 15, driving the rotating plate 11 to rotate around the round rod 10 as an axis. When the moving bending pipe wheel 14 rotates, it drives the pipe to be bent along the fixed bending mechanism.
