Description

A cutting device for metal material processing Technical Field

[0001] This utility model relates to the field of metal cutting technology, and in particular to a cutting device for metal material processing. Background Technology

[0002] Metal material processing cutting devices are key equipment in the field of metal processing. They are mainly used to separate or process various metal raw materials according to specific size, shape and precision requirements. Metal material processing cutting devices are the key link connecting metal raw materials and finished products. Their core value lies in transforming metal materials into parts or structural components that meet the needs of different industries through precise, efficient and safe cutting methods. However, existing devices are not convenient for cutting tubular metals.

[0003] However, existing technologies, such as Chinese Publication No. CN118492561B, "A Cutting Device for Metal Material Processing," belong to the field of metal cutting technology. This invention discloses a cutting device for metal material processing, including an operating table. Slide rods are fixedly connected to both sides of the operating table, and sliding sleeves are slidably connected to the outer walls of the slide rods. A nozzle is fixedly connected to one side of the sliding sleeve, and a transmission pipe is fixedly connected to the operating table. This device, by setting a driving component, can drive the driving component to run when the operating table moves to one side. The driving component drives the mounting shell and cleaning pad to reciprocate on the guide rail in front of the operating table. The cleaning pad can clean impurities on the guide rail in front, preventing impurities on the guide rail from affecting the movement of the operating table. By setting a striking component, a scraper can clean hard impurities remaining on the guide rail when the mounting shell moves. The striking component can periodically strike the scraper, which facilitates faster cleaning of hard impurities and solves the problem of impurities on the cutting machine track affecting the operation of the cutting machine.

[0004] However, this device does not have a metal tube circumferential cutting structure, so it cannot perform efficient and precise circumferential cutting of metal tubes. It cannot cut around the circumference of the metal tube through specific mechanical design and motion. It cannot solve the limitations of traditional cutting methods in terms of precision, efficiency and material adaptability. It cannot ensure that the cutting surface is perpendicular to the tube axis, which may lead to skewing or burrs that may occur with traditional radial cutting. Summary of the Invention

[0008] In a preferred embodiment, the lifting assembly further includes a positive and negative lead screw. The outer surface of the positive and negative lead screw is rotatably connected to the inside of the bottom shell and extends out to one end.

[0010] In a preferred embodiment, the top of the pressure plate is fixedly connected to two main housings, and multiple outward rods are fixedly connected inside the main housings to place the metal tube to be cut inside the two main housings.

[0011] In a preferred embodiment, one end of the extended rod is rotatably connected to a swing rod, and the end of the swing rod away from the extended rod is rotatably connected to a roller.

[0012] In a preferred embodiment, a sleeve is movably fitted onto the outer surface of the swing rod, and a rotating ring is movably fitted onto the outer surface of multiple sleeves.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, please refer to Figures 1 to 5. This utility model provides a technical solution: a cutting device for metal material processing, including a pressure plate 1, a bottom shell 2 fixedly connected to the top of the pressure plate 1, a lifting shell 3 movably embedded in the inner surface of the bottom shell 2, a cutting blade 4 fixedly connected to the top of the lifting shell 3, a lifting assembly inside the bottom shell 2, the lifting assembly including a liner 5, the outer surface of the liner 5 fixedly connected to the inner surface of the bottom shell 2, a threaded rod 6 rotatably connected inside the liner 5, an inner threaded sleeve 7 threadedly connected to the outer surface of the threaded rod 6, fixing rods 8 fixedly connected to both sides of the inner threaded sleeve 7, the ends of the two fixing rods 8 away from the inner threaded sleeve 7 fixedly connected to the inner surface of the lifting shell 3, a driven bevel gear 9 fixedly connected to the bottom of the threaded rod 6, a driving bevel gear 10 meshing with the outer surface of the driven bevel gear 9, and the driving bevel gear 10... A power rod 11 is fixedly connected to one side. The outer surface of the power rod 11 is rotatably connected to one side of the bottom shell 2. The end of the power rod 11 away from the active bevel gear 10 is fixedly connected to a first adjusting crank 12. Two main housings 20 are fixedly connected to the top of the pressure plate 1. Multiple extension rods 21 are fixedly connected inside the main housing 20. One end of the extension rod 21 is rotatably connected to a swing rod 22. The end of the swing rod 22 away from the extension rod 21 is rotatably connected to a roller 23. A rod sleeve 24 is movably sleeved on the outer surface of the swing rod 22. A rotating ring 25 is movably sleeved on the outer surface of the multiple rod sleeves 24. Multiple worm gears 26 are fixedly connected to the outer surface of the rotating ring 25. A worm 27 is meshed with the outer surface of the multiple worm gears 26. The outer surface of the worm 27 is rotatably connected to the inside of the main housing 20 and extends out one end. A clamping crank 28 is fixedly connected to the extended end of the worm 27.

[0025] In this embodiment, the metal tube to be cut is placed inside the two main housings 20. Then, the worm gear 27 is rotated inside the main housing 20 by the clamping crank 28. The rotating worm gear 27, under the meshing action of the worm teeth 26, drives the rotating ring 25 to rotate. When the rotating ring 25 rotates, it drives the internal rod sleeve 24, causing the swing rod 22 to swing with the extension rod 21 as the axis. The swing rod 22 fixes the metal tube through the roller 23, so that the metal tube can only rotate and cannot move. Then, the first adjusting crank 12 drives the power rod 11 to rotate on one side of the bottom housing 2. The driving bevel gear 10, which follows the rotation of the power rod 11, drives the threaded rod 6 to rotate inside the liner 5 under the meshing action of the driven bevel gear 9. The rotating thread drives the internal threaded sleeve 7. Since the internal threaded sleeve 7 is fixed inside the lifting housing 3 by the fixing rod 8, the rotating thread drives the lifting housing 3 to rise inside the bottom housing 2, and causes the cutting blade 4 to apply pressure to the metal tube. Then, by driving the entire metal tube to rotate, the metal tube can be circumferentially cut.

[0026] Example 2, please refer to Figures 1 to 5. The lifting assembly also includes a positive and negative lead screw 13. The outer surface of the positive and negative lead screw 13 is rotatably connected to the inside of the bottom shell 2 and extends out one end. The extended end of the positive and negative lead screw 13 is fixedly connected to a second adjusting crank 14. The outer surface of the positive and negative lead screw 13 is threadedly connected to two internal thread blocks 15. The bottom of the internal thread blocks 15 is fixedly connected to a limiting plate 16. The top of the pressure plate 1 has a limiting groove 17. The outer surfaces of the two limiting plates 16 are movably embedded in the limiting groove 17. The top of the internal thread blocks 15 is rotatably connected to a connecting rod 18. The end of the two connecting rods 18 away from the internal thread blocks 15 is rotatably connected to a fixing plate 19. The outer surface of the fixing plate 19 is fixedly connected to the inner surface of the lifting shell 3.

[0027] In this embodiment, the lifting shell 3 can also be raised by the second adjusting crank 14, which allows the positive and negative lead screws 13 to rotate inside the bottom shell 2. The rotating screw will drive the internal thread block 15. The limiting plate 16 at the bottom of the internal thread block 15 can only move along the slotting direction of the limiting groove 17 opened in the pressure plate 1. Therefore, the rotating screw can drive the two internal thread blocks 15 to move away from each other along the slotting direction of the limiting groove 17, and drive one end of the connecting rod 18 when moving. The other end of the connecting rod 18 will push the fixing plate 19 and the lifting shell 3 so that the cutting blade 4 applies pressure to the metal tube.

[0028] Working principle: First, the metal tube to be cut is placed inside the two main housings 20. Then, the worm gear 27 is rotated inside the main housing 20 by the clamping crank 28. The rotating worm gear 27, under the meshing action of the worm teeth 26, drives the rotating ring 25 to rotate. When the rotating ring 25 rotates, it drives the internal rod sleeve 24, causing the swing rod 22 to swing around the extension rod 21 as the axis. The swing rod 22 fixes the metal tube through the roller 23, so that the metal tube can only rotate and cannot move. Then, the first adjusting crank 12 drives the power rod 11 to rotate on one side of the bottom housing 2. The driving bevel gear 10, which rotates with the power rod 11, drives the threaded rod 6 to rotate inside the liner 5 under the meshing action of the driven bevel gear 9. The rotating thread drives the internal threaded sleeve 7. 7 is fixed inside the lifting shell 3 by the fixing rod 8, so rotating the thread will drive the lifting shell 3 to rise inside the bottom shell 2, and make the cutting blade 4 apply pressure to the metal tube. Then, by driving the metal tube to rotate as a whole, the metal tube can be circumferentially cut. The lifting shell 3 can also be raised by the second adjusting crank 14 to make the positive and negative screw 13 rotate inside the bottom shell 2. Rotating the thread will drive the internal thread block 15. The limiting plate 16 at the bottom of the internal thread block 15 can only move along the slotting direction of the limiting groove 17 opened in the pressure plate 1. So rotating the thread can drive the two internal thread blocks 15 to move away from each other along the slotting direction of the limiting groove 17, and drive one end of the connecting rod 18 when moving. The other end of the connecting rod 18 will push the fixing plate 19 and the lifting shell 3, so that the cutting blade 4 applies pressure to the metal tube.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
