Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting technology, specifically to a laser-flame composite cutting device. Background Technology
[0002] Flame cutting is widely used in the cutting of thick carbon steel plates, but its cutting speed is slow and the piercing time is long. Laser-flame composite cutting machines solve these problems, improving product quality and efficiency.
[0003] Existing laser-flame composite cutting equipment, when cutting sheet metal workpieces, suffers from drawbacks. Because laser-flame composite cutting typically operates at high speeds, it can cause problems when cutting low-melting-point materials. Insufficient preheating of the material at the cutting edge can lead to some molten material rapidly solidifying and forming a shape at the cutting edge. The airflow may not be able to remove this solidified material in time, resulting in a small accumulation of small metal particles on the workpiece surface. This requires manual post-cutting cleaning, making the equipment impractical. Therefore, designing a more practical laser-flame composite cutting system is essential. Utility Model Content

[0018] 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.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a laser flame composite cutting device, including a mounting base 1, a laser generator 2 mounted on one side of the mounting base 1, a flame injector 3 mounted on the bottom of the laser generator 2, a toothed disc 4 movably mounted on the outer wall of the flame injector 3, a sliding groove is formed on the upper part of the toothed disc 4 along the radial direction, and a sliding shell 6 is slidably arranged in the sliding groove, a second motor 62 is fixedly mounted on the top of the sliding shell 6, a rotating shaft 68 is connected to the output end of the second motor 62, a rotating disk 67 is connected to the bottom of the rotating shaft 68, and a plurality of ceramic scrapers 61 are evenly mounted on the bottom of the rotating disk 67. When using it for cutting, the laser generator 2 emits a laser, and the flame injector 3 is activated to cut the workpiece. The circumferential position of the ceramic scraper 61 is adjusted by rotating the toothed disc 4, and the radial position of the ceramic scraper 61 is adjusted by moving the position of the sliding shell 6. The second motor 62 is activated to make the rotating shaft 6 drive the rotating disk 67 to rotate, scraping the surface of the workpiece and removing small metal particles.
[0020] The sliding shell 6 is rotatably connected to the rotating disk 67. The rotating disk 67 has through holes 671 evenly distributed. A connecting pipe 66 is connected through one side of the sliding shell 6. An air pump 63 is connected through the top of the connecting pipe 66. The air pump 63 is connected to an external air source. The air pump 63 is installed above the motor 62. When the air pump 63 is started, external compressed air will be pumped into the connecting pipe 66 and then into the interior of the sliding shell 6. It will then be discharged downward from the through hole 671. At this time, the surface of the scraped workpiece is cleaned by airflow pumping, which improves the cleaning effect of scraping.
[0021] An extension frame 5 is fixedly installed on the outer wall of the flame injector 3. A motor 51 is fixedly installed on the top of the extension frame 5. A drive gear 52 is connected to the output end of the motor 51. The drive gear 52 meshes with the gear disk 4. By starting the motor 51, the drive gear 52 is driven to rotate, thereby driving the gear disk 4 to rotate, so that the position of the ceramic scraper 61 can be adjusted.
[0022] Permanent magnets 64 are installed on both sides of the sliding shell 6. Multiple electromagnets 65 are installed in a straight line along the outer wall of both sides of the slide groove above the toothed disc 4. The electromagnets 65 and permanent magnets 64 are magnetically engaged with each other. The electromagnets 65 are electrically connected to an external power source. When the sliding shell 6 needs to be adjusted to a certain radial position, the power supply of the corresponding electromagnet 65 is turned on. At this time, it becomes magnetic when energized, attracting the permanent magnets 64 to the aligned position above it, which facilitates the adjustment of the position of the sliding shell 6. By combining rotation adjustment and translation adjustment, it is easy to control the ceramic scraper 61 to move to any position around the nozzle below the flame injector 3. Since the movement trajectory of the flame injector 3 is known in advance, the ceramic scraper 61 can always be adjusted so that the scraping trajectory of the ceramic scraper 61 always follows the workpiece cutting trajectory by setting the program.
[0023] A bearing sleeve 7 is installed in the middle of the gear disc 4. Multiple grooves 73 are evenly distributed around the inner wall of the bearing sleeve 7. A spring 72 is installed inside each groove 73. A positioning bead 71 is located on one side of each spring 72. Multiple positioning grooves 31 are vertically formed on the outer wall of the flame injector 3. The inner wall of each positioning groove 31 is arc-shaped and interlocks with the positioning bead 71. The outer and inner rings of the bearing sleeve 7 can slide smoothly against each other. To ensure smooth rotation of the gear disc 4, the bearing sleeve 7 controls the vertical position of the gear disc 4. The toothed disc 4 is fixed in place and can rotate smoothly without interference. When it is necessary to adjust the up and down position of the toothed disc 4, the appropriate up and down position is selected according to the thickness and other parameters of the workpiece. Then, the bearing sleeve 7 is given an upward or downward force so that the positioning bead 71 can squeeze the spring 72 and retract into the inside of the groove 73. At this time, the positioning bead 71 is in contact with the outer wall of the flame injector 3. The position of the toothed disc 4 is adjusted up and down. When it is adjusted to the position of the positioning groove 31 at the appropriate height, the positioning bead 71 enters the positioning groove 31 for up and down positioning due to the squeezing force of the spring 72.
[0024] The tooth width of the drive gear 52 is greater than the thickness of the tooth disk 4. When the tooth disk 4 is adjusted up and down, the drive gear 52 can always mesh with the tooth disk 4.
[0025] By installing a toothed disc or other structure on the outer wall of the flame injector, and by flexibly adjusting the position of the ceramic scraper and controlling its rotation, the surface of the cut workpiece is scraped to remove small metal particles solidified on the workpiece surface. At the same time, airflow is used to clean the surface to prevent small metal particles from accumulating on the workpiece surface. This cleaning method does not require a separate scraping process and can dynamically adjust the scraping position according to the cutting path, making cleaning convenient.
