[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Referring to Figures 1-3 , an embodiment provided by the present invention: A bending connecting pipe forming machine for iron bed production and processing includes a workbench 1. Support frames 2 are fixedly connected to the front and rear sides of the workbench 1. A first motor 3 is fixedly connected to the top of the support frame 2. A first rotating shaft 4 is fixedly connected to the driving end of the first motor 3. The outer wall of the first rotating shaft 4 is rotatably connected to the inner wall of the top of the support frame 2. A rotating rod 5 is fixedly connected to the bottom of the first rotating shaft 4. An extension rod 6 is slidably connected to the inner wall of the rotating rod 5. The top of the bending block 8 is fixedly connected to the bottom of the extension rod 6 for bending an iron pipe. A first screw rod 7 is threadedly connected to the inner wall of the extension rod 6. The left end of the first screw rod 7 is rotatably connected to the inner wall of the left end of the rotating rod 5. A second motor 9 is fixedly connected to the bottom of the workbench 1. A second rotating shaft 10 is fixedly connected to the driving end of the second motor 9. A turntable 11 is fixedly connected to the outer wall of the second rotating shaft 10. The outer wall of the second rotating shaft 10 is rotatably connected to the inner wall of the workbench 1. A plurality of connecting rods 13 are arranged on the inner wall of the turntable 11. The bottom ends of the connecting rods 13 are fixedly connected with moving plates 14. The outer walls of the moving plates 14 are slidably connected to the inner wall of the workbench 1. The bottom ends of the bending dies 15 are fixedly connected to the tops of the moving plates 14 for changing the size of the iron pipe bending. A plurality of arc-shaped grooves 12 are formed in the inner wall of the turntable 11. The connecting rods 13 are all slidably connected to the inner walls of the arc-shaped grooves 12.

[0026] Specifically, start the second motor 9 to drive the second rotating shaft 10 to rotate. The second rotating shaft 10 drives the turntable 11 to rotate. The turntable 11 drives the connecting rod 13 to move outward through the arc-shaped groove 12. The connecting rod 13 drives the moving plate 14 to slide outward. The moving plate 14 drives the bending die 15 to expand outward, thereby increasing the radius generated when the iron pipe is bent. While the position of the bending die 15 changes, rotate the first screw rod 7 to drive the extension rod 6 to move. The extension rod 6 drives the bending block 8 to move and always approach the bending die 15. Then pass the iron pipe through between the bending block 8 and the bending die 15. Finally, start the first motor 3. The first motor 3 drives the first rotating shaft 4 to rotate, thereby driving the rotating rod 5 to rotate. The rotating rod 5 drives the bending block 8 to rotate around the bending die 15 through the extension rod 6 to bend the iron pipe, enabling the same device to produce iron pipes with different bending degrees and improving production flexibility.

[0027] Referring to Figure 1 , Figure 4 and Figure 5, a plurality of sliding grooves 16 are formed at the top end of the workbench 1. Sliders 17 are slidably connected to the inner walls of the sliding grooves 16. First fixing blocks 18 are fixedly connected to the top ends of the sliders 17. Second screw rods 21 are rotatably connected to the rear ends of the first fixing blocks 18. Second fixing blocks 19 are threadedly connected to the outer walls of the second screw rods 21 for clamping the iron pipe between the first fixing blocks 18 and the second fixing blocks 19. Slide rods 20 are fixedly connected to the four sides at the rear ends of the plurality of first fixing blocks 18. The outer walls of the four-side slide rods 20 are slidably connected to the inner walls of the second fixing blocks 19. A third screw rod 22 is threadedly connected to the inner wall of the first fixing block 18. A threaded sleeve 23 is threadedly connected to the outer wall of the third screw rod 22. The outer wall of the threaded sleeve 23 is slidably connected to the inner wall of the first fixing block 18. An extrusion block 24 is fixedly connected to the bottom end of the threaded sleeve 23. A pressure-receiving block 25 is arranged at the bottom end of the extrusion block 24. The outer wall of the pressure-receiving block 25 is slidably connected to the inner wall of the slider 17 for fixing the first fixing block 18.

[0028] Specifically, the plurality of first fixing blocks 18 and second fixing blocks 19 on the workbench 1 slide to the position of the bending die 15 and change to a horizontal position at the rear side by relying on the sliders 17 at the bottom ends in the sliding grooves 16. Then, the iron pipe is passed through the middle of the plurality of first fixing blocks 18 and second fixing blocks 19. Then, the second screw rod 21 is rotated to drive the second fixing block 19 to approach the first fixing block 18 to fix the iron pipe. Subsequently, the third screw rod 22 is rotated to drive the threaded sleeve 23 to move downward. The threaded sleeve 23 drives the extrusion block 24 to move downward, causing the extrusion block 24 to squeeze the pressure-receiving blocks 25 on both sides to move outward, thereby squeezing the pressure-receiving blocks 25 against both sides of the inner wall of the sliding groove 16 to fix the slider 17, so that the first fixing block 18 is fixed to prevent the overall movement of the first fixing block 18 and the second fixing block 19.

[0029] Working principle: When in use, the second motor 9 can be started to drive the second rotating shaft 10 to rotate, thereby driving the turntable 11 to rotate. The turntable 11 drives the connecting rod 13 to move outwards through the arc-shaped groove 12. The connecting rod 13 drives the moving plate 14 to slide outwards. The moving plate 14 drives the bending die 15 to expand outwards, increasing the radius generated during the bending of the iron pipe. Then, the multiple first fixing blocks 18 and second fixing blocks 19 on the workbench 1 slide on the sliding grooves 16 by means of the sliders 17 at the bottom to the corresponding positions after the expansion of the bending die 15. Then, the iron pipe is passed through the middle of the multiple first fixing blocks 18 and second fixing blocks 19, and through the space between the rear side of the bending die 15 and the bending block 8. Then, the second screw rod 21 is rotated to drive the second fixing block 19 to approach the first fixing block 18 to fix the iron pipe. Subsequently, the third screw rod 22 is rotated to drive the threaded sleeve 23 to move downwards. The threaded sleeve 23 drives the extrusion block 24 to move downwards, causing the extrusion block 24 to extrude the two pressure-receiving blocks 25 to move outwards, thereby extruding on both sides of the inner wall of the sliding groove 16 to fix the slider 17. After that, the first screw rod 7 is rotated to drive the extension rod 6 to move, so as to drive the bending block 8 to approach the bending die 15. Finally, the first motor 3 is started. The first motor 3 drives the first rotating shaft 4 to rotate, thereby driving the rotating rod 5 to rotate. The rotating rod 5 drives the bending block 8 to rotate around the bending die 15 through the extension rod 6 to bend the iron pipe.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
