Description

Technical Field

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

[0002] Laser cutting is a process in which laser light is emitted from a laser device and focused into a high-power density laser beam through an optical path system to replace a traditional mechanical knife. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach a melting point or boiling point, while high-pressure gas blows away the molten or vaporized metal. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. Most of the existing cutting tables are arranged in an array of several serrated plates with equal spacing, which can reduce the contact area between the cutting platform and the plate when cutting. However, most of the serrated plates on the existing cutting platforms are fixed, so that when the plate is loaded, a lifting device or other transfer devices are required to assist in loading. When auxiliary loading is used, straps or other components are required to fix the plate, so that when the plate is moved to the cutting platform, the straps need to be removed, and in the process, the cutting platform will scratch one side of the plate.

[0003] The announcement number is: CN117245235B, which discloses a plate laser cutting device. During loading and unloading, the first drive component drives the support bar on the support unit to retract to avoid scratching the plate. When the plate is placed on the frame for cutting, the first drive component drives the support bar to extend to support the plate. After the plate is cut and unloaded, the second drive component drives each support unit to rotate to remove debris adhering to the support bar.

[0004] However, when the laser cutting device is transmitting and loading the plate, the support bar is in a retracted state, but when the plate needs to be lifted, the support bar needs to be extended, but the two support bars inside a cylinder need to contact the bottom end of the plate at the same time. When the two support bars are extended and drive the plate to rise, the support bars will scratch the bottom end of the plate, and there will be scratches at the contact point between each support bar and the plate, thereby affecting the appearance of the plate. Although the cylinder is cylindrical, the debris generated during laser cutting will still fall directly above the cylinder and will not fall off. Since the debris generated by the cutting is in a high-temperature state and the cylinder is not provided with a cooling component, after the debris falls on the cylinder, more debris will stick and adhere to the cylinder, so that when the cylinder transports the cut plate, the debris attached to the cylinder will also cause damage to the plate.

[0005] Based on this, a laser cutting device is now provided, which can eliminate the disadvantages of the existing devices. Summary of the invention

When in use, when it is necessary to cut the plate, the third motor 42 is started, and the third motor 42 drives the mounting shaft to rotate, and the mounting shaft drives several second friction discs 37 to rotate through several active bevel gears. Under the action of the tension spring 46, the second friction disc 37 is tightly attached to the first friction disc 33, so that the second friction disc 37 drives the rotating roller 30 to rotate. When the rotating roller 30 rotates, the plate can be transported, thereby facilitating the plate to be moved to the processing position.

[0035] The correction mechanism includes a correction friction plate 47, and several correction wheels 34 are equipped with correction friction plates 47. Rollers 35 are symmetrically rotated at the plane of the correction wheel 34. One side of the correction friction plate 47 is fixedly connected to the output ends of several spring telescopic rods 48 respectively. The spring telescopic rods 48 are fixedly arranged on one side of the sliding rack 49. Limit rods 50 are slidably arranged on both sides of the sliding rack 49. The limit rods 50 are fixedly arranged on the upper end of the second support plate 54. A moving gear 51 is meshed on one side of the sliding rack 49. The moving gear 51 is rotatably arranged at one end of the connecting frame 52. The frame 52 is fixed on one end of the lifting plate 25, and a first guide groove is provided on one side of the cutting table 24 at a position corresponding to the position of the connecting frame 52. A fixed rack 53 is meshed on the moving gear 51, and the fixed rack 53 is fixed on the upper end of the second support plate 54. Both ends of the correction friction plate 47 are inclined. A rotating joint 36 is rotatably provided at one end of the fixed tube 32, and several of the rotating joints 36 are connected to the conveying pipe. The input end of the conveying pipe is connected to the output end of the external air supply component.

[0036] The pushing assembly includes a push rod 45, and the other end of the lifting plate 25 is fixed with a push rod 45, and the cutting table 24 is provided with a second guide groove at the corresponding position of the push rod 45. One end of the push rod 45 is closely provided with a guide plate 44, and several guide plates 44 are respectively fixed on one side of several second rotating plates. When in use, after the rotating roller 30 transports the plate to the processing place, the external control component controls several hydraulic cylinders 29 to start, and the output ends of several hydraulic cylinders 29 drive the mounting frame 27 to move through the connecting plate 28, and the mounting frame 27 drives several lifting plates 25 to rise. The lifting plates 25 lift the sheet material and keep it away from the rotating roller 30. During the movement of the lifting plates 25, the lifting plates 25 drive the push rod 45 and the connecting frame 52 to move, and the connecting frame 52 drives the moving gear 51 to move. In the initial state, the correction friction plate 47 and the correction wheel 34 are separated. Before one end of the correction friction plate 47 contacts the correction wheel 34, the push rod 45 first pushes the guide plate 44 to move, and the guide plate 44 drives the inner spline shaft 38 to move through the second rotating plate, so that the second friction plate 37 is separated from the first friction plate 33, and the second friction plate 37 is in contact with the first friction plate 33. After the wiping plate 33 is separated, the correction friction plate 47 is in close contact with the correction wheel 34.

If the exhaust hole on the rotating roller 30 is not aligned with the working position at this time, the correction friction plate 47 and the outer arc-shaped part of the correction wheel 34 are in close contact with each other, so that the correction wheel 34 drives the rotating roller 30 to rotate, and the output end of the spring telescopic rod 48 is compressed. When the exhaust hole on the rotating roller 30 is aligned with the working position, the two ends of the correction wheel 34 are in close contact with each other. The rollers 35 are in close contact with the correction friction plate 47, so that the correction wheel 34 no longer rotates when the correction friction plate 47 moves. When the lifting plate 25 stops moving, the correction friction plate 47 is separated from the correction wheel 34, and the second friction disk 37 is in close contact with the first friction disk 33 again. Then the laser cutting body 11 cuts the plate. At this time, the external air supply component transports gas to the inside of the several rotating rollers 30, and the gas is preferably cold air. Since the lifting plates 25 are provided on both sides of the rotating rollers 30, the cold air flows upward along one side of the lifting plates 25, so that the lifting plates 25 and the plates can be cooled.

[0037] First scraper bars 26 are tightly attached to both sides of the lifting plate 25. Several of the first scraper bars 26 are fixed on the inner side of the cutting table 24. The upper ends of the first scraper bars 26 are inclined. When in use, after the laser cutting body 11 completes cutting of the plate, the mounting frame 27 drives the plate to descend. At this time, the lifting plate 25 slides between the two first scraper bars 26, so that the first scraper bars 26 can remove impurities attached to both sides of the lifting plate 25.

[0038] A plurality of collecting boxes 55 are provided at the bottom of the laser cutting body 11, which are convenient for collecting the debris generated during the cutting of the laser cutting body 11. Meanwhile, cooling liquid can be placed inside the collecting box 55 to cool the high-temperature debris.

[0039] Embodiment 2: The difference from Embodiment 1 lies in that a cooling tube 15 is fixedly provided at the working end of the laser cutting body 11, and the interior of the cooling tube 15 is hollow. A liquid inlet tube 16 and a liquid outlet tube 17 are provided at the bottom end of the cooling tube 15, and the working end length of the liquid outlet tube 17 is greater than the working end length of the liquid inlet tube 16. One end of the liquid inlet tube 16 and the liquid outlet tube 17 are respectively connected to the working ends of the outer liquid supply component and the external liquid pumping component. During use, when the laser cutting body 11 works for a long time, the internal parts of the working end of the laser cutting body 11 will generate high temperature. At this time, the external liquid supply component and the external liquid pumping component work at the same time, so that the coolant flows inside the cooling tube 15, thereby cooling the working end of the laser cutting body 11.

[0040] The outer side of the cooling pipe 15 is rotatably provided with a connecting pipe 18, and the connecting pipe 18 and the outer side of the cooling pipe 15 are combined into a closed space. A spiral plate 19 is fixedly provided on the inner side of the connecting pipe 18, and a fixing ring 21 is rotatably provided at one end of the connecting pipe 18. The input end of the fixing ring 21 is connected with an air intake pipe, and one end of the air intake pipe is connected with the output end of the external air supply component. The bottom end of the connecting pipe 18 is connected with an injection pipe 20, and the output end of the injection pipe 20 is inclined. A gear ring 22 is fixedly provided on the connecting pipe 18, and a driving gear is meshed on the gear ring 22. The driving gear is fixedly provided on the output end of the second motor 23, and the second motor 23 is fixedly provided at the bottom end of the mounting frame. When in use, when the laser cutting main When the body 11 is cutting the plate, the external air supply equipment transports gas to the inside of the fixed ring 21 through the air inlet pipe. The gas flows around the outside of the cooling tube 15 under the action of the spiral plate 19. The gas can exchange heat with the coolant inside the cooling tube 15 during the flow, so as to increase the cooling effect on the working end of the laser cutting body 11. The gas is then discharged through the jet pipe 20. The gas in the jet pipe 20 can clean up the debris generated when the laser cutting body 11 is cut. At the same time, the gas provided by the external air supply equipment is preferably cold gas. In this application, the laser cutting body 11, the external air supply component, the external liquid supply component and the external exhaust component are all prior art and can be selected according to actual use. They will not be described in detail here.

[0041] The above embodiment discloses a laser cutting device, wherein when it is necessary to cut a plate, the third motor 42 is started, the third motor 42 drives the mounting shaft to rotate, and the mounting shaft drives the second friction discs 37 to rotate through the plurality of active bevel gears. Under the action of the tension spring 46, the second friction disc 37 is tightly attached to the first friction disc 33, so that the second friction disc 37 drives the rotating roller 30 to rotate. When the rotating roller 30 rotates, the plate can be transported. After the rotating roller 30 transports the plate to the processing location, the external control component controls the plurality of hydraulic cylinders 29 to start, and the output ends of the plurality of hydraulic cylinders 29 drive the mounting frame 27 to move through the connecting plate 28, and the mounting frame 27 drives the plurality of lifting plates 25 to move upward. The lifting plates 25 lift the plate and make the plate away from the rotating roller 30. During the movement of the lifting plates 25, the lifting plates 25 drive the push rod 45 and the connecting frame 52 to move, and the connecting frame 52 drives the moving gear 51 to move. In the initial state, the correction friction plate 47 and the correction wheel 34 are separated. Before one end of the correction friction plate 47 contacts the correction wheel 34, the push rod 45 first pushes the guide plate 44 to move, and the guide plate 44 drives the inner spline shaft 38 to move through the second rotating plate, so that the second friction plate 37 is separated from the first friction plate 33. After the second friction plate 37 is separated from the first friction plate 33, the correction friction plate 47 is in close contact with the correction wheel 34. Since the moving gear 51 follows the connecting frame 52 moves, and the moving gear 51 meshes with the fixed rack 53, so that the moving distance of the sliding rack 49 is several times the moving distance of the moving gear 51. If the exhaust hole on the rotating roller 30 is not aligned with the working position at this time, the correction friction plate 47 and the outer arc-shaped part of the correction wheel 34 are rubbed tightly, so that the correction wheel 34 drives the rotating roller 30 to rotate, and the output end of the spring telescopic rod 48 is compressed. When the exhaust hole on the rotating roller 30 is aligned with the working position, the two rollers 35 on the correction wheel 34 are tightly attached to the correction friction plate 47, so that the correction wheel 34 no longer rotates when the correction friction plate 47 moves. When the lifting plate 25 stops moving, the correction friction plate 47 is separated from the correction wheel 34, and the second friction plate 37 is re-engaged. The first friction disc 33 is tightly attached to the new plate, and then the laser cutting body 11 cuts the plate. At this time, the external air supply component delivers gas to the inside of the plurality of rotating rollers 30, and the gas is preferably cold air. Since the lifting plates 25 are provided on both sides of the rotating rollers 30, the cold air flows upward along one side of the lifting plates 25, so that the lifting plates 25 and the plate can be cooled. When the high-temperature debris generated by the laser cutting body 11 when cutting the plate falls on the upper end of the rotating roller 30, part of the debris slides off the rotating roller 30. Since the cold air is discharged through the exhaust holes on the rotating roller 30, the cold air can cool the rotating roller 30, and the high-temperature debris falling on the upper end of the rotating roller 30 can be cooled by the rotating roller 30.

[0042] When the laser cutting body 11 works for a long time, the internal parts of the working end of the laser cutting body 11 will generate high temperature. At this time, the external liquid supply component and the external liquid extraction component work at the same time, so that the coolant flows inside the cooling tube 15. When the laser cutting body 11 cuts the plate, the external air supply device conveys gas to the inside of the fixing ring 21 through the air inlet pipe. The gas flows around the outside of the cooling tube 15 under the action of the spiral plate 19. During the flow of the gas, the coolant inside the cooling tube 15 can be heat exchanged, so that the cooling effect on the working end of the laser cutting body 11 can be increased, and then it is discharged through the air jet pipe 20. The gas in the air jet pipe 20 can clean up the debris generated when the laser cutting body 11 is cut;

[0043] When the plate cutting is completed and the cut plate needs to be placed on the upper end of the rotating roller 30, the third motor 42 is first started to drive the plurality of rotating rollers 30 to rotate. When the rotating rollers 30 rotate, the second scraper rod 31 can scrape off the debris attached to the surface of the rotating roller 30. Then the output end of the hydraulic cylinder 29 drives the lifting plate 25 to move to the initial position. During this process, the first friction disc 33 is first separated from the second friction disc 37, and then the correction friction plate 47 is rubbed tightly against the correction wheel 34. After the lifting plate 25 stops, the second friction disc 37 is again tightly attached to the first friction disc 33, and the cut plate moves to the upper end of the rotating roller 30.

[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
