[0033] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a bending device for metal pipe processing, including a table board 1. The table board 1 is penetrated and rotatably connected with a bending turntable 2 at the top. A first bevel gear 3 is fixedly connected to the bottom of the bending turntable 2. A motor 5 is fixedly connected to the bottom of the table board 1. A second bevel gear 4 is fixedly connected to the output shaft of the motor 5. By rotating the second bevel gear 4 through the output shaft of the motor 5, and then meshing and rotating the first bevel gear 3 through the second bevel gear 4, the first bevel gear 3 meshes with the second bevel gear 4. A bending rod 6 is fixedly connected to the top of the bending turntable 2. A bending rod platform 8 is fixedly connected to the top of the bending rod 6. A first pressing rod 9 is penetrated and threadedly connected to the top of the bending rod platform 8. A first fixing block 10 is rotatably connected to the bottom of the first pressing rod 9. By rotating the first pressing rod 9 to descend, and then driving the first fixing block 10 to press down through the first pressing rod 9, and then adjusting the height downward by sliding the first fixing block 10 in the two bending rods 6. A fixing rod 12 is slidably connected to the inner wall of the table board 1. A fixing rod platform 13 is fixedly connected to the top of the fixing rod 12. A second pressing rod 14 is penetrated and threadedly connected to the top of the fixing rod platform 13. A second fixing block 15 is rotatably connected to the bottom of the second pressing rod 14. The height of the second fixing block 15 is adjusted by rotating the second pressing rod 14. Limiting components are arranged at the tops of both the first fixing block 10 and the second fixing block 15. A clamping plate component is fixedly connected to the outer wall of the fixing rod 12.
[0034] Referring to Figure 1 - Figure 2 , a sliding groove 22 is opened at the top of the table board 1. A threaded rod 23 is rotatably connected to the top end of the left inner wall of the sliding groove 22. A crank 21 is fixedly connected to the outer end of the threaded rod 23. A sliding rod 24 is fixedly connected to the top end of the right inner wall of the sliding groove 22. The threaded rod 23 penetrates and is threadedly connected to the bottom of the fixing rod 12. The sliding rod 24 penetrates and is slidably connected to the bottom of the fixing rod 12. The distance between the fixing rod 12 and the bending rod 6 is adjusted by rotating the threaded rod 23 through the crank 21.
[0035] Referring to Figure 3 - Figure 4 , a first limiting groove 7 is opened on the outer wall of the bending rod 6. A second limiting groove 16 is opened on the outer wall of the fixing rod 12. The outer end of the limiting lock block 27 is clamped with the first limiting groove 7 through the spring 26 to rebound. The outer end of the limiting lock block 27 is released from the limit of the first limiting groove 7 by pulling the limiting switch 28.
[0036] Referring to Figure 4 - Figure 5, the clamping plate assembly includes a clamping plate threaded rod 20. A clamping plate connecting frame 18 is slidably connected to the outer wall of the clamping plate threaded rod 20. Two clamping plates 17 are fixedly connected to both sides of the clamping plate connecting frame 18. A clamping plate nut 19 is threadedly connected to the outer wall of the clamping plate threaded rod 20. Two groups of clamping plate springs 25 are fixedly connected to the back of the clamping plate connecting frame 18, which is used to have a stronger relative squeezing force when the clamping plates 17 clamp the pipe inward. The bottom ends of the clamping plate springs 25 are fixedly connected to the outer wall of the fixed rod 12. By rotating the clamping plate nut 19, the clamping plates 17 are driven to move back and forth to adjust the diameter of the pipe. The elastic force of the clamping plate springs 25 will reset the clamping plate connecting frame 18.
[0037] Referring to Figure 6 , the limiting assembly includes a limiting lock frame 11. A limiting lock block 27 is elastically connected to the limiting lock frame 11 through a spring 26. The limiting lock block 27 is provided with a chamfered slope.

The top end of the spring 26 is fixedly connected to the inner wall of the limiting lock frame 11. The bottom of the spring 26 is fixedly connected to the limiting lock block 27. A limiting switch 28 is fixedly connected to the top of the outer wall of the limiting lock block 27. By pulling the limiting switch 28, the limiting lock block 27 is driven to be pulled to release the limit, and then the limiting lock block 27 is rebounded by the spring 26 to be clamped to the inner wall of the first limiting groove 7 to complete the limit.
[0038] Working principle: When placing the pipe before the bending work, push the pipe from the middle of the fixed rod 12 to the middle of the bending rod 6. Adjust the height of the second fixed block 15 through the second pressing rod 14 on the fixed rod 12, and then rebound the limiting lock block 27 into the second limiting groove 16 through the spring 26 to complete the limit. Similarly, the first fixed block 10 on the bending rod 6 and the second fixed block 15 on the fixed rod 12 are adjusted to the same height to realize the bending work of multiple pipes at the same time.
[0039] During the debugging stage of the bending work, push the pipe from the middle of the fixed rod 12 to the middle of the bending rod 6. According to the different lengths of the pipes, rotate the threaded rod 23 through the crank 21, so that the fixed rod 12 threadedly connected to the threaded rod 23 slides on the inner wall of the sliding groove 22, thereby solving the problem of different pipe lengths. By rotating the clamping plate nut 19 threadedly connected to the clamping plate threaded rod 20, the clamping plate connecting frame 18 is driven to stretch back and forth with the clamping plates 17, so that pipes with different diameters can all carry out the bending work.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
