Description
Technical Field
[0001] This utility model belongs to the field of cutting equipment technology, and in particular relates to a cutting device for metal pipe processing. Background Technology
[0002] Laser cutting is one of the methods of cutting workpieces. Laser cutting uses a laser beam to melt the material being cut, and then a high-speed jet of air blows away the molten material, thereby achieving the effect of cutting the workpiece. Because laser cutting is efficient and stable, laser cutting devices are also used when cutting some pipes.
[0003] Patent CN119187949A discloses a high-efficiency laser cutting equipment and method for processing metal pipes, including a base, a housing, a rotating seat, and a support frame mounted on the upper end of the base. A material conveying component is installed inside the rotating seat, and a cutting component is installed inside the support frame. The material conveying component includes a material changing mechanism and a positioning mechanism. The cutting component includes a rolling mechanism and a slitting mechanism. The material changing mechanism includes a drive column, a material changing roller, a storage trough, and a support steel roller. The material changing mechanism is used for loading and unloading metal pipes, the positioning mechanism is used for correcting the position of the metal pipes, the rolling mechanism is used for controlling the rotation of the metal pipes, and the slitting mechanism is used for cutting the metal pipes. This invention, through the action of the cutting component, positions the metal pipes while simultaneously controlling their rotation. Subsequently, multiple laser cutting guns simultaneously complete multiple cuts on the metal pipes, thereby improving the cutting efficiency of the metal pipes.
[0004] In existing technologies, multiple laser cutting guns and rubber friction wheels can be used to cut metal pipes in multiple places. However, the following problems still exist in overall use: First, when cutting multiple metal pipes, the existing technology lays the metal pipes flat between two rollers. If there are protrusions, bends, or other non-straight parts on the surface of the metal pipes, it will cause the metal pipes to tilt, resulting in a change in the cutting angle and affecting the cutting effect. Second, when cutting metal pipes, rust on the surface of the metal pipes will affect the laser cutting effect and reduce the precision of laser cutting. Existing equipment cannot clean the rust from the pipes before cutting. Utility Model Content

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] refer to Figure 1 and Figure 2 A cutting device for processing metal pipes includes a machine body 10, with supports 14 at both ends of the machine body 10. Each support 14 has a positioning plate 21 inside, and the outer surface of each positioning plate 21 has multiple positioning holes 37. Multiple fixing blocks 22 are slidably disposed on one side of each positioning hole 37 inside the positioning plate 21. The clamping ends of the fixing blocks 22 are arc-shaped, which facilitates a closer fit between the fixing blocks 22 and the arc-shaped surface of the pipe, increasing friction and improving the clamping effect. Each component is equipped with multiple sliding clamping blocks 24, the clamping ends of which are also arc-shaped. The multiple clamping blocks 24 and the fixing block 22 can clamp the metal pipe. Each of the multiple positioning holes 37 has a rotatable cleaning ring 29 inside. The cleaning ring 29 is annular in shape, and multiple brushes 31 are provided on the inner circular surface of the cleaning ring 29. After the cleaning ring 29 rotates, it can drive the multiple brushes 31 to rub and clean the outer surface of the metal pipe, thereby cleaning the rust and impurities on the outside of the metal pipe and improving the cutting accuracy.
[0026] Further reference Figure 1 and Figure 2 The outer surface of the positioning plate 21 is symmetrically provided with multiple sliding grooves 38, which are slidably connected to the fixing block 22. The fixing block 22 is provided with protrusions on both sides, which can restrict the movement direction of the fixing block 22 and prevent the fixing block 22 from rotating. The fixing block 22 is provided with a threaded rod 23 inside the threaded drive. One end of the threaded rod 23 is rotatably connected to the positioning plate 21. Rotating the threaded rod 23 can drive the fixing block 22 to adjust its height to adapt to various specifications of pipes and structures, thereby improving the adaptability of the device.
[0027] Further reference Figure 1 and Figure 2 A drive rod 25 is slidably mounted on the end face of the positioning plate 21. A first cylinder 36 is mounted on the outside of the bracket 14. The output shaft of the first cylinder 36 is fixedly connected to one end of the drive rod 25. Multiple connecting rods 26 are rotatably mounted on the outer surface of the drive rod 25. The multiple connecting rods 26 are rotatably connected to multiple clamping blocks 24 respectively. The multiple clamping blocks 24 are symmetrically arranged, and each clamping block 24 has a rotating connector at its bottom. The rotating connector is rotatably connected to the connecting rod 26. When the drive rod 25 moves, it will drive the connecting rod 26 to move, causing the connection between the connecting rod 26 and the drive rod 25 to rotate, and causing the connecting rod 26 to push the clamping blocks 24 connected on both sides to move, thereby fixing the pipeline.
[0028] Further reference Figure 3 , Figure 4 and Figure 5The positioning plate 21 has a movable plate 27 slidably mounted inside, and the bracket 14 has a second cylinder 35 mounted outside. The output shaft of the second cylinder 35 is fixedly connected to one end of the movable plate 27. Both ends of the movable plate 27 are equipped with racks 28, and the racks 28 are externally equipped with gears 30 for meshing transmission. The gears 30 are fixedly connected to the cleaning ring 29. The output shaft of the second cylinder 35 continuously reciprocates, causing the movable plate 27 to drive the racks 28 to reciprocate. During the reciprocating movement of the racks 28, the gears 30 continuously drive the gears 30 to reciprocate and rotate. The gears 30 then drive the brush 31 inside the cleaning ring 29 to rotate, so that the brush 31 cleans the outer surface of the metal pipe, reduces rust residue, and thus improves the cutting effect.
[0029] Further reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The outer surface of the cleaning ring 29 is provided with multiple air holes 32. A cavity 33 is provided on one side of the cleaning ring 29 and inside the positioning plate 21. The air holes 32 are connected to the cavity 33. An air pump 34 is provided on one side of the bracket 14. The air pump 34 is connected to the inside of the cavity 33 through a hose. A collection box 13 is provided at the other end of the air pump 34. A grid plate 11 is provided on the end face of the machine body 10. A partition is provided between the grid plate 11 and the machine body 10. A fan 12 is provided at the bottom end of the grid plate 11. The air outlet of the fan 12 is connected to the inside of the collection box 13. The waste generated by cutting falls into the inside of the machine body 10 through the grid plate 11 for collection. At the same time, by setting the fan 12, a negative pressure can be generated inside the partition to absorb the air and prevent the spread of odor generated by cutting, thereby improving the health of the workers. By setting the air pump 34, the air inside the cavity 33 can be extracted and the scraped rust and impurities can be adsorbed through the air holes 32 and discharged into the inside of the collection box 13 for collection.
[0030] Further reference Figure 1 Each of the two brackets 14 has a first slide rail 15 on its end face. Each of the two first slide rails 15 has a first slider 16 slidably mounted on its outer side. Each of the two first sliders 16 has a second slide rail 17 on its top end face. Each of the two first sliders 17 has a second slider 18 slidably mounted on its outer side. Each of the two sliders 18 has a mounting bracket 19 on its end face. Each of the two mounting brackets 19 has a laser cutting machine 20 mounted on one side. By setting the second slide rail 17 and the first slide rail 15, the laser cutting machine 20 can move more flexibly and improve the cutting accuracy.
[0031] In operation, the second cylinder 35 is first activated, causing it to reciprocate continuously and move the movable plate 27. The movable plate 27 then drives the rack 28 to reciprocate. During this reciprocating motion, the rack 28 continuously drives the meshing gear 30 to rotate, which in turn rotates the brush 31 inside the cleaning ring 29. As the brush 31 rotates, it feeds metal pipes of different specifications into the cleaning ring 29, bringing the brush 31 into contact with the outer surface of the metal pipes. The rotating brush 31 cleans the outer surface of the metal pipes, reducing rust and improving cutting accuracy. Then, the air pump 34 is activated, drawing air from the cavity 33 through a hose and using the air holes 32 to absorb the scraped rust and impurities, further cleaning the inside of the cleaning ring 29. The parts and brush 31 are cleaned to improve the service life of brush 31, and impurities are discharged into the collection box 13 for collection, which is convenient for unified cleaning. During this process, the fan 12 is started to absorb the air in the partition, so that the partition is negatively pressured to absorb the air and prevent the spread of odors generated by cutting, thereby improving the health of the workers. The gas is discharged into the collection box 13 for collection. Then, the fixed block 22 is moved by rotating the threaded rod 23. The first cylinder 36 is started, which drives the drive rod 25 to move. After the drive rod 25 moves, it drives the connecting rod 26 to move, so that the connection between the connecting rod 26 and the drive rod 25 rotates, and the connecting rod 26 pushes the clamping blocks 24 connected on both sides to move, so that the pipe is abutted against the arc-shaped surface of the fixed block 22 to fix the pipe.
