Description

Technical Field

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

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. When processing metal pipes, a metal plate laser cutting machine is also required.

[0003] In the prior art, a Chinese invention patent with patent number CN118060746A discloses a metal plate laser cutting machine, which relates to the technical field of laser processing of metal plates, and includes a workbench, wherein both sides of the bottom of the workbench are fixedly connected with a support frame and a support frame in sequence along the left-right direction, and the right sides of the front and back of the top of the workbench are fixedly connected with a fixed plate, and the tops of the fixed plates close to each other are fixedly connected with an electric slide rail seat, and a cylinder is provided on one side of the electric slide rail seat through an extension seat, and the piston rod of the cylinder is fixedly connected with a bottom plate, and a laser cutting head is embedded in the bottom plate.

[0004] In the above-mentioned prior art, although the design of the purging and collecting assembly can blow away the metal debris from the cutting seam and quickly collect the metal debris above the metal plate body at the same time, it can effectively prevent the metal debris above the metal plate body from being directly blown away and scattered on the workbench, greatly reducing the difficulty of subsequent cleaning, and the entire purging and collecting process is fully electronically controlled, simple, convenient and easy to operate. However, when the metal pipe is ring cut, a large amount of slag and debris generated can easily fall below the cutting seam of the metal pipe and be located on the inner surface of the metal. After the slag cools, it adheres to the inner surface of the metal pipe, increasing the difficulty of cutting and making it difficult to clean. Summary of the invention

Meanwhile, the waste gas and dust generated are sucked into the filter box by the first fan for filtration and purification, and the waste gas and dust generated during laser cutting are filtered and processed to protect the surrounding working environment. 5. In the present invention, nitrogen can effectively blow away the material melted by the laser, making it easier for the laser to cut the workpiece, thereby increasing the cutting speed and reducing the heat conduction around the material, thereby improving the cutting quality and accuracy. Nitrogen can also reduce the oxygen content in the cutting area, reducing the risk of fire and explosion. 6. In the present invention, the first cylinder drives the pressure plate connected thereto to move downward, so that the roller presses on the upper surface of the workpiece, so that the workpiece remains stable during the rotation process during the ring cutting, thereby improving the quality of the cutting. At the same time, when the workpiece is cut, the upper and lower clamps can fix the cut workpiece, thereby improving the use effect. 7. In the present invention, a first slide groove is provided on the opposite side of the bracket, and a support plate fixed to both sides of the pressing plate is slidably installed inside the first slide groove to improve the stability of the pressing plate during its upward and downward sliding process.

[0025] Furthermore, when in use, the first motor 21 rotates to drive the first bevel gear 22 to rotate, thereby causing the screw rod 20 to rotate in the second slide groove 19 through the meshing second bevel gear 23, thereby causing the slider 24 to slide in the second slide groove 19.

[0026] refer to Figure 4 A third slide groove 26 is provided on the front surface of the slider 24, a mounting plate 27 is slidably installed inside the third slide groove 26, a laser cutter 28 is fixedly installed on the front surface of the mounting plate 27, a cutting head 29 is fixedly installed on the bottom of the laser cutter 28, a second cylinder 25 is fixedly installed on the upper surface of the slider 24, the output end of the second cylinder 25 passes through the slider 24, slides with the slider 24, and is fixed to the top of the mounting plate 27.

[0027] Furthermore, during use, when cutting, the second cylinder 25 drives the mounting plate 27 to move downward in the third slide groove 26, thereby driving the laser cutter 28 to move downward. The distance of the cutting head 29 can be adjusted according to the diameter of the workpiece 3 to improve the use effect. At the same time, it can cooperate with the slider 24 to move left and right, and can cut workpieces 3 of any length, which is practical. Embodiment 2:

Both sides of the gas storage pipe 30 are connected to a conduit 33 that runs through the inside of the fixed block 32. The conduit 33 is used for the cutting head 29 to be correspondingly arranged.

[0029] Furthermore, during use, when the cutting head 29 cuts the workpiece 3, a cutting seam is formed, so that the nitrogen can effectively blow away the material melted by the laser from the crack, making it easier for the laser to cut the workpiece 3, thereby increasing the cutting speed. At the same time, it can reduce heat conduction around the material, improve cutting quality and accuracy, and nitrogen can also reduce the oxygen content in the cutting area, reducing the risk of fire and explosion.

[0030] refer to Figure 1 and Figure 5 A sleeve 34 is fixedly mounted on the front surface of the slider 24, and an arc-shaped groove is formed at the bottom of the sleeve 34 for fitting the workpiece 3.

[0033] refer to Figure 6 and Figure 7 A fourth slide groove 42 is provided on the lower surface of the base 1, and a U-shaped support rod 43 is slidably installed inside the fourth slide groove 42. The support rod 43 runs through one side of the base 1, and a third cylinder 41 is fixedly installed on the lower surface of the base 1 and located on one side of the fourth slide groove 42. The output end of the third cylinder 41 is connected and fixed to the lower surface of the support rod 43 through a plate. An electric telescopic rod 44 is fixedly installed at one end of the support rod 43, and a box 45 is fixedly installed at the output end of the electric telescopic rod 44.

[0034] Furthermore, when in use, the third cylinder 41 is used to push out the support rod 43, and then the box 45 is pulled back to be sent into the interior of the workpiece 3, located at the cutting seam of the workpiece 3, to catch the waste falling from the seam. The support rod 43 is used in conjunction with the electric telescopic rod 44 to reduce the use space of the support rod 43 extending out.

[0035] refer to Figure 8A semicircular receiving plate 47 is fixedly installed in the inner cavity of the box body 45, and the receiving plate 47 divides the box body 45 into a receiving bin 46 and a cooling bin, and the receiving plate 47 is hollowed out so that waste materials will not fall from the holes. A second fan 51 fixedly installed at the bottom of the inner cavity of the box body 45 is arranged inside the cooling bin, and an exhaust hole 52 is opened on one side of the box body 45.

[0036] Furthermore, when in use, the cut waste falls into the receiving bin 46 and is located on the upper surface of the receiving plate 47. The second fan 51 blows air to the outside through the exhaust hole 52, thereby accelerating the air flow at the receiving plate 47, cooling the waste residue, accelerating its forming speed, and facilitating subsequent processing work.

[0037] refer to Figure 7 and Figure 8 A second motor 48 is fixedly installed on one side of the receiving bin 46, and transmission shafts 49 are rotatably installed on both sides of the inner cavity of the receiving bin 46. The transmission shafts 49 are separately arranged to facilitate the falling of cut waste and prevent the waste from adhering to the transmission shaft 49 and hindering the normal work. The output end of the second motor 48 is fixed to its transmission shaft 49, and a U-shaped scraper 50 used in conjunction with the receiving plate 47 is fixedly installed on the surface of the transmission shaft 49.

[0038] Furthermore, when in use, the second motor 48 is a servo motor, and the second motor 48 reciprocatingly rotates in a semicircle to drive the transmission shaft 49 connected thereto to rotate, thereby driving the scraper 50 to rotate, which is used to separate the waste adhered to the receiving plate 47 from the receiving plate 47, making it easier to remove the waste and facilitate subsequent processing work.

[0039] refer to Figure 7 A fixing plate 53 symmetrical to the cutting seam is fixedly installed on the top of the inner cavity of the receiving bin 46, and a sliding rod 54 runs through the inside of the fixing plate 53 and slides with the fixing plate 53. A pad is provided in the middle of the sliding rod 54 to prevent the sliding rod 54 from sliding off the fixing plate 53, and a top column 55 is slidably installed on the top of the sliding rod 54, and a spring 56 inside the sliding rod 54 is fixedly installed at the bottom of the top column 55, and an eccentric disk 57 used in conjunction with the sliding rod 54 is fixedly installed on the corresponding end of the transmission shaft 49.

[0040] Furthermore, when in use, while the scraper 50 rotates, it drives the drive shaft 49 on the other side to rotate, so that the two drive shafts 49 drive the two eccentric disks 57 to rotate at the same time. When the eccentric disk 57 rotates upward away from one end of the drive shaft 49, the slide bar 54 is squeezed to move upward, thereby driving the top column 55 to move upward, and then the top column 55 hits the two sides of the cutting seam, causing the cutting seam to vibrate, and does not cause the workpiece 3 to move. With the use of nitrogen, the laser-melted material is quickly blown away from the crack, and the speed at which the cutting waste falls is accelerated. The timely removal of the waste avoids the blockage and contamination of the cutting seam, ensures the smoothness and cleanliness of the cutting surface, and improves the cutting quality. At the same time, the rapid falling of the waste reduces the subsequent cleaning and grinding processes. The telescopic arrangement between the top column 55 and the slide bar 54 is convenient for the use of workpieces 3 with different diameters.
