Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting processing, in particular to a laser cutting auxiliary device for metal processing. Background Art

[0002] Laser cutting is a CNC process that uses high-energy laser power to cut different materials. The technology produces a concentrated beam by stimulating the laser material through an electric discharge in a closed container. Optics are used to focus the laser beam on the workpiece, allowing cutting by melting, vaporization or burning.

[0003] Publication No.: CN118720458A discloses a laser cutting device for metal parts, comprising: a machine table, a cutting mechanism for cutting parts, an adjusting mechanism for adjusting the cutting position, the cutting mechanism comprising: a protective shell, a protective plate slidably mounted on the bottom of the protective shell, a guide member for guiding the protective plate, a laser cutting head, a cylinder sleeved on the laser cutting head, a reset assembly for driving the laser cutting head to reset, a cooling assembly for cooling the laser cutting head, a dust removal assembly for removing dust from the laser cutting head, and a drying assembly for drying parts. The device solves the problem that the existing laser cutting device cannot cool the laser cutting head in time during use, which easily causes the laser cutting head to overheat. This affects the cutting efficiency and service life. However, in actual use, the device and existing equipment do not perform a cleaning step on the metal surface during laser cutting. Since the temperature at the metal port increases after laser cutting, if there are certain impurities on the metal surface before processing, it is easy to form impurity oxides at the metal fracture after laser cutting. The oxide reduces the metal properties at the metal fracture, resulting in a decrease in the processing quality of the metal during subsequent processing. In addition, cooling the metal by cooling the metal easily leads to a large temperature difference between the metal processing area and other areas, thereby forming a large cutting temperature gradient and thermal stress, which increases the degree of deformation of the metal after cutting and reduces the processing quality of the device. The laser cutting quality of existing equipment has further room for improvement. Summary of the Invention

[0046] Working principle: Place several processed metals in the first fixing clamp 30 and the second fixing clamp 432 adapted thereto, then turn on the first rotation drive assembly 40, the first rotation drive assembly 40 turns on and drives the first rotating shaft 400 to rotate, the first rotating shaft 400 rotates and drives the first bevel gear 41 and the first screw 50 to rotate, the first bevel gear 41 rotates and drives the second bevel gear 42 to rotate, the second bevel gear 42 rotates and drives the worm 420 to rotate, the worm 420 rotates and drives several worm gears 430 to rotate, the worm gear 430 rotates and drives several second fixing clamps 432 to rotate through the fixing rod 431, the second fixing clamps 432 rotate together with the rotating shaft The first fixing clamp 30 connected to the inner wall of the fixing device 3 rotates to drive the processed metal to rotate. At this time, the heating device 31 is turned on. The heating device 31 is turned on to blow hot air toward the processed metal through the through holes of the support plate 32 to heat it. Since the processed metal is constantly rotating at this time, the hot air surrounds the processed metal in a circular shape to fully heat the processed metal. By reducing the cutting temperature gradient and thermal stress, the deformation degree of the processed metal after laser cutting is reduced. At the same time, the surface temperature of the processed metal is consistent to avoid the large temperature difference inside the processed metal after laser cutting, which leads to the increase of thermal stress inside the processed metal and the increase of metal deformation. The laser processing quality of the device is improved and it is convenient for users to use.

[0047] In the above steps, the first screw 50 rotates to drive the first movable block 51 to move. Since the first movable block 51 is limited by the slide bar 52, the first movable block 51 performs a linear motion toward the rear side. The movement of the first movable block 51 drives the processing chamber 53 to move through the slide bar 52. The movement of the processing chamber 53 drives several cleaning plates 530 to move from the surface of the processed metal, simulating the wiping movement of human hands to clean the surface of the processed metal of impurities. Since the processed metal is always rotating in the above steps, the movement of the processing chamber 53 can comprehensively clean the impurities of the processed metal, thereby avoiding the oxidation reaction of impurities on its surface after laser cutting, which causes the metal properties at the fracture of the processed metal to change, resulting in a reduction in the processing quality of the metal during subsequent processing, thereby improving the laser cutting processing quality of the device and facilitating user use.

[0048] After the above steps are completed, the conveying device 10 is turned on, and the conveying device 10 moves the cutting device 11 to the cutting position of the processed metal. Then, the cutting device 11 is turned on to cut the processed metal. Since compressed gases such as oxygen and nitrogen are generally used in existing laser cutting to assist the cutting device 11 in laser cutting, and compressed gas is easily sprayed during processing to spray water droplets and impurities and adhere to the cutting lens 13, thereby dispersing the laser focus and causing the cutting head 12 to be unable to cut normally, the electric turntable 540 is turned on at this time, and the electric turntable 540 drives the processing chamber 53 to rotate counterclockwise by 90 degrees through the second shaft 54 so that the several processing cylinders 55 are facing the several cutting lenses 13. At this time, the second rotation drive assembly 551 is turned on, and the second rotation drive assembly 551 drives the second rotating shaft 552 to rotate. The rotation of the second rotating shaft 552 drives the first gear plate 553 to rotate. The rotation of the first gear plate 553 drives the second gear plate 57 to rotate. The second gear plate 57 rotates through the adjusting arm 570 and the mounting rod 571 to drive the adjusting chamber 572 and the fourth bevel gear 573 to rotate. In the initial position, the third bevel gear 561 and the fourth bevel gear 573 are not in contact. The adjusting chamber 572 rotates through the bottom rod 581 and the telescopic rod 582 to drive the side plate 583 to rotate. At this time, the center of the cut lens 13 is cleaned by the processing disk 563 with a concave inner wall, and the cut lens 13 is cleaned. The other areas are cleaned by rotating the arc-shaped side plate 583, so that the overall cleaning range of the adjustment chamber 572 conforms to the convex lens shape of the general cutting lens 13, making it more complete and avoiding the situation of cleaning dead corners. When the overall size of the cutting lens 13 is large, the linear drive component 56 is turned on, and the linear drive component 56 pushes out and moves the output rod 560. The movement of the output rod 560 drives the third bevel gear 561 to engage with the fourth bevel gear 573. At this time, repeating the above steps can make the adjustment chamber 572 and the fourth bevel gear 573 rotate at the outer surface of the third bevel gear 561. The fourth bevel gear 573 rotates on the outer surface of the third bevel gear 561 to rotate. The fourth bevel gear 573 rotates by adjusting The rod 574 drives the second screw 575 to rotate, and the rotation of the second screw 575 drives the second movable block 58 to perform linear motion. The through rod 580 and the third through slot are used to limit the second movable block 58. The movement of the second movable block 58 drives the bottom rod 581, the telescopic rod 582, and the side plate 583 to perform a rotational motion with an increasing radius. The elastic member and the telescopic rod 582 are used to ensure that the side plate 583 can always fit with the convex lens-shaped cutting lens 13. In this way, the device is suitable for cleaning a wide range of cutting lenses 13, avoiding the situation where the laser focus is dispersed when water droplets or impurities appear on the surface of the cutting lens 13, resulting in the cutting head 12 being unable to cut normally, thereby improving the laser processing quality of the device and facilitating user use.
