Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting device for metal processing. Background Technology

[0002] A laser cutting head focuses a laser beam emitted from a laser source into a high-power-density beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] Currently, in the process of metal sheet processing, a laser cutting head is used to cut the metal sheet to obtain the parts needed in the production process. In the operation, the metal sheet is generally placed directly on the laser cutting head, and the metal sheet is supported by multiple sets of vertically arranged triangular plates on the laser cutting head. Then, the movement of the laser cutting head is controlled to cut the metal sheet. However, during the cutting process, the parts do not fall off after being cut. It is necessary to wait until all the parts are cut before they can be removed from the laser cutting head. Then, the waste material is removed before cutting the next set of metal sheets, resulting in low production efficiency. To address this, we propose a laser cutting device for metal processing.

[0008] Preferably, the pushing component includes two sets of connecting pipes symmetrically installed inside the laser cutting machine body. One end of the connecting pipe is connected to a blower, and the other end of the connecting pipe is connected to a diverter pipe. Multiple sets of connecting pipes are connected to the diverter pipe, and a sleeve is connected to the end of the connecting pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention provides a laser cutting device for metal processing. Multiple sets of rotating rollers are arranged on both sides of the laser cutting machine body to support the metal sheet. Then, a pushing component pushes two sets of connecting plates closer together. When the two sets of connecting plates approach each other, all the support plates on both sides of the laser cutting machine body move closer together. During this process, the metal sheet's compression causes the sliding ring to move, thus moving the moving rod. The moving rod then moves the moving plate, which in turn moves the moving column. The moving column then causes the connecting block to pull the rotating rod. During this process, the rotating rod rotates, changing the angle of the rotating tube. Therefore, the rotating rod... The function of the connecting column causes the connecting column to move, which in turn drives the sliding block to move, thus moving the clamping plate. The movement of the clamping plate compresses the metal sheet, thereby fixing the metal sheet. As a result, during the metal sheet cutting process, there are no obstructions at the bottom of the metal sheet, allowing the cut parts to automatically fall onto the conveyor belt. Then, in conjunction with the conveying component, the cut parts are automatically transported to the next process, thereby improving the processing efficiency of the metal sheet. By fixing the metal sheet through the action of the fixing component and the conveying component, and ensuring that there are no obstructions at the bottom of the metal sheet during fixing, it is easy for the cut parts to fall onto the conveying component and be automatically transported to the next process. Therefore, this solves the problem of low metal processing efficiency in the prior art. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9 This invention provides a technical solution: a laser cutting device for metal processing, comprising a laser cutting machine body 1, a fixing component 6, and a conveying component 10. A horizontal rail 2 is mounted on the laser cutting machine body 1, a slide rail 3 is slidably connected to the horizontal rail 2, and a cutting head 4 is slidably connected to the slide rail 3. Multiple sets of parallel support rollers 5 are also rotatably connected to the laser cutting machine body 1. The fixing component 6 includes two sets of connecting plates 7, which are symmetrically installed on both sides of the laser cutting machine body 1. Multiple sets of support plates 8 are fixedly connected to the connecting plates 7, and rotating rollers 9 are rotatably connected to the support plates 8. The fixing component 6 supports the metal sheet through the action of the rotating rollers 9 and clamps and fixes the metal sheet through the movement of the connecting plates 7. The conveying component 10 is mounted on the laser cutting machine body 1 and connected to the fixing component 6. The conveying component 10 is used to convey the cut metal parts to the next process.

[0029] In this scheme, when fixing the metal sheet, one end of the metal sheet is first placed on the support roller 5, and then the metal sheet is slowly pushed so that the end of the metal sheet is placed on the rotating roller 9. At this time, the metal sheet is fixed by the fixing component 6. After fixing, the metal sheet is cut by the laser cutting machine body 1 and the cutting head 4. Since the bottom of the metal sheet is not blocked after the fixing component 6 fixes the metal sheet, the cut metal parts will fall onto the conveying component 10. Then, the cut metal parts are conveyed to the next process by the conveying component 10.

[0030] The fixing component 6 includes a sliding block 11 slidably connected to the support plate 8 and a pushing member 18 connected to the connecting plate 7. The support plate 8 has a groove 12 adapted to the sliding block 11. A clamping plate 13 is fixedly connected to one side of the sliding block 11 on the rotating roller 9. A connecting column 14 slidably connected to the support plate 8 is fixedly connected to the other side of the sliding block 11. A rotating rod 15 is rotatably connected to the connecting column 14. A connecting block 16 is rotatably connected to one end of the rotating rod 15. A moving member 17 for moving the connecting block 16 is connected to the connecting block 16. The moving member 17 includes a sliding ring 19 sleeved on the outer side of the rotating roller 9. A moving rod 20 is fixedly connected to the sliding ring 19. The moving rod 20 passes through the support plate 8 and is connected to the support plate 7. 8. A sliding connection is made, and a moving plate 21 is fixedly connected to the moving rod 20. One end of the moving plate 21 is fixedly connected to a first tension spring 22 that is fixedly connected to the support plate 8, and the other end of the moving plate 21 is fixedly connected to a moving column 23. A fixing ring 24 that is fixedly connected to the connecting block 16 is fixedly connected to the moving column 23. The pushing component 18 includes two sets of connecting pipes 25 symmetrically installed inside the laser cutting machine body 1. One end of the connecting pipe 25 is connected to a blower 26, and the other end of the connecting pipe 25 is connected to a diverter pipe 27. Multiple sets of connecting pipes 28 are connected to the diverter pipe 27. The end of the connecting pipe 28 is connected to a sleeve 29. A movable block 30 is slidably connected inside the sleeve 29. A movable rod 31 that is fixedly connected to the connecting plate 7 is fixedly connected to the movable block 30.

[0031] In this scheme, when fixing the metal sheet, the metal sheet is first placed on multiple sets of support rollers 5, and then the metal sheet is slowly pushed. During this process, gas is supplied into the connecting pipe 25 by the action of the blower 26. The gas then enters the diversion pipe 27 through the connecting pipe 25, and then enters the connecting pipe 28 and the sleeve 29 through the action of the diversion pipe 27. After the gas enters the sleeve 29, the air pressure inside the sleeve 29 will increase, thus causing the movable block 30 to move. The movement of the movable block 30 drives the movable rod 31 to move. Therefore, the movement of the movable rod 31... The action drives the connecting plate 7 to move. At this time, the two sets of connecting plates 7 move closer to each other, thereby driving the support plates 8 located on both sides of the laser cutting machine body 1 to move closer to each other, and further driving the rotating rollers 9 on both sides of the laser cutting machine body 1 to move closer to each other. When the metal sheet can be placed on the rotating roller 9, the blower 26 stops starting until the metal sheet is pushed away from the support roller 5. At this time, the metal sheet is completely placed on the rotating roller 9. Then the blower 26 is started again. The start of the blower 26 will once again drive the two sets of connecting plates 7 to move closer to each other, thereby making the support plates 8 on both sides of the laser cutting machine body 1 move closer to each other. As plate 8 moves, it drives the sliding ring 19 to move. The movement of the support plate 8 and the sliding ring 19 causes the metal sheet and the sliding ring 19 to press against each other, thus causing the sliding ring 19 to move. This movement of the sliding ring 19 drives the moving rod 20 to move, which in turn drives the moving plate 21 to move. The moving plate 21 then drives the moving column 23 to move. As the moving plate 21 moves, the first tension spring 22 is stretched. The moving column 23 then causes the connecting block 16 to pull the rotating rod 15 to move. During this process… In the process, the rotating rod 15 will rotate, causing the angle of the rotating tube to change. Therefore, the connecting column 14 will move due to the action of the rotating rod 15. The movement of the connecting column 14 will drive the sliding block 11 to move, which in turn will drive the clamping plate 13 to move. The movement of the clamping plate 13 will squeeze the metal sheet, thereby fixing the metal sheet. Thus, during the cutting process of the metal sheet, there is no obstruction at the bottom of the metal sheet, so the cut parts will automatically fall onto the conveying assembly 10. Then, with the action of the conveying assembly 10, the cut parts will be automatically conveyed to the next process.

[0032] In this scheme, after cutting, the reverse drive of the blower 26 reduces the air pressure inside the sleeve 29. At this time, the movable block 30 and the movable rod 31 will reset. The reset of the movable rod 31 will reset the connecting plate 7 and the support plate 8. After the support plate 8 resets, the sliding ring 19 will gradually move away from the metal sheet. At this time, the first tension spring 22 will gradually reset. Therefore, the sliding ring 19 will reset through the action of the first tension spring 22, which will in turn reset the moving rod 20 and the moving plate 21. When the moving plate 21 resets, it will drive the moving column 23 to reset. The action of the moving column 23 will reset the rotating rod 15 and the connecting column 14. At this time, the clamping plate 13 will reset and move away from the metal sheet. Therefore, after cutting, the reverse drive of the blower 26 will loosen the metal sheet. Then the cut waste will fall onto the conveying assembly 10 and be conveyed by the conveying assembly 10. Then, the next set of metal sheets will be processed.

[0033] Preferably, the blower 26 includes a motor 32 fixed inside the laser cutting machine body 1. The output end of the motor 32 is fixedly connected to a coupling 33. One end of the coupling 33 is fixedly connected to a drive shaft 34. A fan wheel 35 is fixedly connected to the drive shaft 34. A fan cover 36 is sleeved on the outside of the fan wheel 35. The fan cover 36 is connected to two sets of connecting pipes 25. A sealing pipe 37 is also connected to the fan cover 36. A sealing element 38 is installed inside the sealing pipe 37. The sealing element 38 includes a fixing plate 39 fixed inside the sealing pipe 37. The fixing plate 39 has several sets of through holes 40. A fixing post 41 is fixedly connected to the fixing plate 39. A sealing block 42 is slidably connected to the fixing post 41. A sealing ring 43 fixedly connected to the sealing pipe 37 is movably connected to the outer side of the sealing block 42. A second tension spring 44 is fixedly connected between the sealing block 42 and the fixing plate 39.

[0034] In this scheme, by starting the motor 32, the motor 32 will drive the coupling 33 to rotate, and the coupling 33 will drive the drive shaft 34 to rotate. When the drive shaft 34 rotates, it will drive the impeller 35 to rotate. The rotation of the impeller 35 generates wind power. At this time, the gas will enter the diversion pipe 27 through the connecting pipe 25, and then enter the connecting pipe 28 and the sleeve 29 through the diversion pipe 27. After the clamp 13 contacts the metal sheet, the connecting plate 7 and the support plate 8 can no longer move. Therefore, the air pressure inside the sleeve 29 reaches its peak value. At this time, the wind power generated by the continuous rotation of the impeller 35 will blow into the sealing pipe 37, which will increase the air pressure inside the sealing pipe 37. At this time, the air pressure will push the sealing block 42 to move, thereby moving the sealing block 42 away from the sealing ring 43. At this time, the gas will be discharged through the gap between the sealing block 42 and the sealing ring 43, thus circulating the wind power.

[0035] The conveying assembly 10 includes two sets of fixed legs 45, and a first transmission roller 46 is rotatably connected between the two sets of fixed legs 45. A conveyor belt 47 that passes through the laser cutting machine body 1 is rotatably connected to the outer side of the first transmission roller 46. The conveyor belt 47 is installed at the bottom end of the rotating roller 9, and the other end of the conveyor belt 47 is rotatably connected to a second transmission roller 48 that is rotatably connected to the laser cutting machine body 1. A driven wheel 49 is fixedly connected to the second transmission roller 48. A belt 50 is rotatably connected to the outer side of the driven wheel 49. One end of the belt 50 is rotatably connected to a drive wheel 51 that is fixedly connected to the drive shaft 34.

[0036] In this scheme, when the drive shaft 34 rotates, it will drive the drive wheel 51 to rotate, which in turn drives the driven wheel 49 to rotate through the belt 50. Then the driven wheel 49 will drive the second transmission roller 48 to rotate, thus driving the conveyor belt 47 to rotate. The metal parts are transported by the rotation of the conveyor belt 47.

[0037] A limiting ring 52 is fixedly connected to the rotating roller 9. Anti-slip particles 53 are provided on the surface of the clamping plate 13 that contacts the metal sheet. Several sets of ventilation holes 54 are opened on the laser cutting machine body 1 at the position of the wind hood 36. Several sets of support legs 55 are fixedly connected to the bottom end of the laser cutting machine body 1.

[0038] In this design, the limiting ring 52 is used to limit the sliding ring 19 and prevent it from separating from the rotating roller 9; the anti-slip particles 53 are used to increase the friction between the clamping plate 13 and the metal sheet, thereby improving the stability of the metal sheet; the ventilation holes 54 facilitate airflow circulation, and the support legs 55 improve the stability of the laser cutting machine body 1.

[0039] Working principle: When processing the metal sheet, it is first necessary to fix the metal sheet. During fixing, the metal sheet is first placed on multiple sets of support rollers 5, and then slowly pushed. During this process, the motor 32 is started, which drives the coupling 33 to rotate. The coupling 33 then drives the drive shaft 34 to rotate, which in turn drives the impeller 35 to rotate. The rotation of the impeller 35 generates airflow, which in turn delivers gas into the connecting pipe 25. The gas then enters the diversion pipe 27 through the connecting pipe 25, and finally, through the diversion pipe 27, enters the connecting pipe 28 and the sleeve 29. After gas enters the sleeve 29, the gas pressure inside the sleeve 29 will increase, causing the movable block 30 to move. The movement of the movable block 30 drives the movable rod 31 to move, which in turn drives the connecting plate 7 to move. At this time, the two sets of connecting plates 7 move closer together, thereby causing the support plates 8 located on both sides of the laser cutting machine body 1 to move closer together, which in turn causes the rotating rollers 9 on both sides of the laser cutting machine body 1 to move closer together. When the metal sheet can rest on the rotating roller 9, the motor 32 stops starting. This continues until the metal sheet is pushed away from the support roller 5, at which point the entire metal sheet is placed on the rotating roller 9. When motor 32 is started again, it will once again drive the two sets of connecting plates 7 to move closer together, thereby causing the support plate 8 to move. During the movement of the support plate 8, the sliding ring 19 will move, and the movement of the support plate 8 and the sliding ring 19 will cause the metal sheet to press against the sliding ring 19, thus causing the sliding ring 19 to move. The movement of the sliding ring 19 will then drive the moving rod 20 to move, which in turn drives the moving plate 21 to move. The moving plate 21 will then drive the moving column 23 to move, causing the first tension spring 22 to stretch. This stretching will then be achieved through the movement of the moving column 23. The action of the connecting block 16 causes the rotating rod 15 to move. During this process, the rotating rod 15 will rotate, causing the angle of the rotating tube to change. Therefore, the action of the rotating rod 15 causes the connecting column 14 to move. The movement of the connecting column 14 drives the sliding block 11 to move, which in turn drives the clamping plate 13 to move. The movement of the clamping plate 13 squeezes the metal sheet, thereby fixing the metal sheet. Thus, during the cutting process of the metal sheet, there is no obstruction at the bottom of the metal sheet, so that the cut parts automatically fall onto the conveying assembly 10. Then, with the action of the conveying assembly 10, the cut parts are automatically conveyed to the next process.

[0040] In this scheme, after cutting, the reverse drive of motor 32 reduces the air pressure inside sleeve 29. At this time, movable block 30 and movable rod 31 will reset. The reset of movable rod 31 causes connecting plate 7 and support plate 8 to reset. After support plate 8 resets, sliding ring 19 gradually moves away from metal sheet. At this time, first tension spring 22 will gradually reset. Therefore, the action of first tension spring 22 causes sliding ring 19 to reset, which in turn causes moving rod 20 and moving plate 21 to reset. When moving plate 21 resets, it will drive moving column 23 to reset. The action of moving column 23 causes rotating rod 15 and connecting column 14 to reset. At this time, clamping plate 13 will reset and move away from metal sheet. Therefore, after cutting, the reverse drive of motor 32 causes metal sheet to loosen. Then the cut waste will fall onto conveying component 10 and be conveyed by conveying component 10. Then the next set of metal sheets will be processed.

[0041] After the fixing is completed, the metal sheet is cut by the action of the cutting head 4. During this process, the motor 32 is always rotating. Therefore, the action of the motor 32 causes the drive shaft 34 to rotate, and the rotation of the drive shaft 34 will also cause the drive wheel 51 to rotate, which in turn drives the driven wheel 49 to rotate through the action of the belt 50. Then the driven wheel 49 will drive the second transmission roller 48 to rotate, thus driving the conveyor belt 47 to rotate. Therefore, the cut parts will fall directly onto the conveyor belt 47, and the metal parts are transported by the rotation of the conveyor belt 47.
