[0029] Please see Figures 1 to 4 A metal pipe cutting device includes a base 1, a first bracket 2 fixedly connected to the top of one side of the base 1, and a sliding bracket 3 slidably disposed on the top inner side of the first bracket 2.

[0030] The first bracket 2 has a groove 4 at the position corresponding to the sliding bracket 3. The top of the sliding bracket 3 is fixedly connected to the top of the groove 4. The screw 6, which is threadedly connected to the slider 5, is rotatably connected inside the groove 4. The first bracket 2 is mounted on the outside of the screw 6. The shaft end of the first motor 7 is fixedly connected to the screw 6. A cutting mechanism is mounted on the sliding bracket 3. The top of the other side of the base 1 is mounted on the second bracket 14. The top of the inner side of the base 1 is symmetrically fixedly connected to the fixed clamping frame 15. The second bracket 14 is provided with a lifting clamping frame 16 at the position corresponding to the fixed clamping frame 15. The middle of the second bracket 14 and the lifting clamping frame 16 are connected through a lifting groove 17.

[0031] A lifting rod 18 is fixedly connected to the top of the lifting clamp 16 corresponding to the lifting groove 17. A guide groove 19 is passed through the second bracket 14 near both sides of the lifting clamp 16. A guide rod 20 is fixedly connected to the top of the lifting clamp 16 corresponding to the guide groove 19. A toothed groove 21 is opened on the side of the lifting rod 18 near the middle of the second bracket 14. Transmission teeth 22 are fixedly connected at equal intervals on the inner side of the toothed groove 21. A transmission gear 23 is rotatably connected to the bottom inner side of the second bracket 14 corresponding to the transmission teeth 22. A fourth motor 24 is installed on the upper part of the second bracket 14 near the middle. The fourth motor 24 drives the transmission gears 23 on both sides to rotate in the same direction through the transmission mechanism.

[0032] When the fourth motor 24 is working, it drives the two transmission gears 23 on both sides to rotate in the same direction through the transmission mechanism. When the fourth motor 24 drives one of the lifting clamping frames 16 to rise and fall through the meshing of the transmission gears 23 and the transmission teeth 22, the other lifting clamping frame 16 moves in the opposite direction, so that the two lifting clamping frames 16 rise and fall alternately, thereby clamping and fixing the two metal pipes alternately. When the first motor 7 is working, it can drive the sliding bracket 3 and the cutting mechanism to move laterally through the threaded connection formed by the slider 5 and the lead screw 6, so that the two metal pipes can be cut alternately, allowing the cutting mechanism to work continuously and the metal pipes to be fed continuously, effectively improving the working efficiency of the metal pipe cutting device.

[0033] Please see Figures 1 to 4 The cutting mechanism includes a protective cover 8. The protective cover 8 is rotatably connected to the inner side of the sliding bracket 3. The cutting blade 9 is rotatably connected inside the protective cover 8. A second motor 10 is installed on the outer side of the protective cover 8 corresponding to the cutting blade 9. The shaft end of the second motor 10 is fixedly connected to the cutting blade 9. A worm gear 11 is fixedly connected to the rotating shaft end of the protective cover 8. A third motor 12 is installed on the outer side of the sliding bracket 3 corresponding to the worm gear 11. A worm 13 that meshes with the worm gear 11 is fixedly connected to the shaft end of the third motor 12. When the second motor 10 is working, it drives the cutting blade 9 to work, which can cut the metal pipe. When the third motor 12 is working, it can drive the protective cover 8 to rotate through the meshing of the worm 13 and the worm gear 11, thereby adjusting the angle of the cutting blade 9 so as to adjust the cutting angle.

[0034] Please see Figures 1 to 4 The guide rod 20 is a cylinder, and the outer diameter of the guide rod 20 matches the inner diameter of the guide groove 19. The tooth pitch of the transmission teeth 22 and the transmission gear 23 is equal, and the transmission teeth 22 and the transmission gear 23 mesh with each other.

[0035] Please see Figures 1 to 4The transmission mechanism includes a rotating shaft 25. The rotating shaft 25 is symmetrically rotatably connected to the lower sides of the second bracket 14 near both sides of the fourth motor 24. A first reversing gear 26 is fixedly connected to the bottom shaft end of the fourth motor 24. A second reversing gear 27 is fixedly connected to one end of the rotating shaft 25 corresponding to the first reversing gear 26. A third reversing gear 28 is fixedly connected to the end of the rotating shaft 25 away from the second reversing gear 27. A fourth reversing gear 29 is fixedly connected to the shaft end of the transmission gear 23 corresponding to the third reversing gear 28. The first reversing gear 26 meshes with the second reversing gear 27, and the third reversing gear 28 meshes with... The fourth reversing gear 29 meshes with the fourth motor 24. When the fourth motor 24 is working, the fourth motor 24 drives the second reversing gears 27 on both sides to rotate in opposite directions through the first reversing gear 26, causing the third reversing gears 28 on both sides to rotate in opposite directions. The third reversing gears 28 drive the transmission gear 23 to rotate through meshing with the fourth reversing gear 29. Since the third reversing gears 28 on both sides are facing opposite directions, the third reversing gears 28 rotating in opposite directions can drive the transmission gears 23 on both sides to rotate in the same direction. Thus, the two lifting clamps 16 can be driven to move in opposite directions simultaneously through a single fourth motor 24.

[0036] Working principle: When using this metal pipe cutting device, such as Figures 1 to 4 As shown, firstly, when the fourth motor 24 is working, it drives the two transmission gears 23 on both sides to rotate in the same direction through the transmission mechanism. This causes the fourth motor 24 to drive one of the lifting clamping frames 16 to rise and fall through the meshing of the transmission gears 23 and the transmission teeth 22. Simultaneously, the other lifting clamping frame 16 moves in the opposite direction, causing the two lifting clamping frames 16 to rise and fall alternately, thus alternately clamping and fixing the two metal pipes. When the first motor 7 is working, through the threaded connection formed by the slider 5 and the lead screw 6, it can drive the sliding bracket 3 and the cutting mechanism to move laterally, enabling the two metal pipes to be cut alternately. This allows the cutting mechanism to work continuously, and the metal pipes to be continuously fed, effectively improving the working efficiency of the metal pipe cutting device. Furthermore, when the second motor 10 is working, it drives the cutting blade 9 to work, enabling... When the metal pipe is cut, the third motor 12, through the meshing of the worm gear 13 and the worm wheel 11, drives the protective cover 8 to rotate, thereby adjusting the angle of the cutting blade 9 to adjust the cutting angle. When the fourth motor 24 is working, the fourth motor 24 drives the second reversing gears 27 on both sides to rotate in opposite directions through the first reversing gear 26, causing the third reversing gears 28 on both sides to rotate in opposite directions. The third reversing gears 28, through meshing with the fourth reversing gear 29, drive the transmission gear 23 to rotate. Since the third reversing gears 28 on both sides are facing opposite directions, the oppositely rotating third reversing gears 28 can drive the transmission gears 23 on both sides to rotate in the same direction. Thus, the single fourth motor 24 can simultaneously drive the two lifting clamps 16 to move in opposite directions.

[0037] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
