Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum material cutting, and specifically relates to a cutting device for aluminum materials of doors and windows. Background Art

[0002] Aluminum doors and windows refer to door and window products made of aluminum materials. The doors and windows are mainly composed of a frame spliced by four aluminum rods, which are beautiful, airtight and high in strength, and are widely used in the field of construction projects. For the manufacture of aluminum rods for doors and windows, usually a cutting device using a step punching action is used to cut the aluminum material plate, and then a bending device is used to bend the cut aluminum material plate to prepare aluminum rods. At the same time, the aluminum rods are spliced and welded by a welding device to complete the production and processing of doors and windows.

[0003] A patent with the publication number CN118893242A discloses a cutting device for aluminum materials of doors and windows. In this device, the aluminum material is placed on the installation base plate, and then the driving device drives the cutting tool to move downward to cut the aluminum material. When the driving device drives the cutting tool to move back to its original position, the driving device drives the belt to rotate through the transmission device, and the belt pushes the aluminum material forward through the pushing device for the next cutting. Then, the size of the aluminum material cutting is adjusted by adjusting the ratio between the driving device and the adjusting transmission device, and the tensioning device keeps the belt taut.

[0004] The above-mentioned solution still has some problems in actual use. Usually, the aluminum material plate is placed on the workbench, and the size of the aluminum material plate to be cut is adjusted at the same time. Then, the step punching equipment is started to drive the cutting tool to cut the aluminum material plate. After the aluminum material plate is cut, it is necessary to first recycle the cut aluminum material plate, and then adjust the aluminum material plate again to adjust the cutting position, and at the same time start the step punching equipment again to cut it. This cutting method is not only difficult to realize the cyclic cutting of the aluminum material plate, but also when the aluminum material plate is not pressed and fixed at both ends during cutting, the cut material is likely to bounce up after step punching cutting, posing a safety hazard to the surrounding operators.

[0014] Preferably, two grinding rollers are rotatably connected between the sliders, and a layer of ceramic particles is arranged on the outside of the two grinding rollers for grinding the cutting edge and the blade surface of the punching knife. A cutting groove is formed on one side of the upper end surface of the workbench, and the two grinding rollers are slidably connected inside the inner cavity of the cutting groove. The cutting groove is used for guiding the recovery of particles such as waste burrs generated during the cutting of the aluminum plate.

[0015] Preferably, grooves are symmetrically arranged on one side of the upper end surface of the workbench. A limiting component is arranged in the inner cavity of the groove.

[0017] The beneficial effects of the present invention are as follows: 1. For a kind of door and window aluminum profile cutting device of the present invention, the mounting plate and the connecting frame drive the fixed cylinder to move downward, and at the same time drive the T-shaped slide bar to move downward, and then drive the pressing plate to press and fix the aluminum profile plate on the workbench. As the mounting plate and the connecting frame continue to move downward, the punching knife cuts the aluminum profile plate on the workbench. At the same time, the punching knife drives the grinding piece to contact above the cutting opening of the aluminum profile plate, and then grinds the cutting opening of the aluminum profile plate as the punching knife moves. After the cutting of the aluminum profile plate is completed, by driving the punching knife to move upward to reset, it will drive the grinding piece to contact below the cutting opening of the aluminum profile plate, and then grind the lower part of the cutting opening of the aluminum profile plate, so as to realize the grinding work of the aluminum profile plate cutting, and improve the preparation efficiency of the door and window aluminum profile cutting.

At the same time, the telescopic rod drives the rubber roller to move downward. During the upward movement of the telescopic rod, the torsion spring twists the fixed disk to rotate, and at the same time drives the rotating shaft to rotate, and then drives the telescopic rod and the rubber roller to rotate. However, due to the influence of the ratchet, the rubber roller is difficult to rotate. Therefore, when the telescopic rod moves upward, the telescopic rod will rotate and reset, and at the same time drive the rubber roller to rotate and reset, and use the rubber roller to push the aluminum profile plate to be transported downward under the U-shaped support frame. The cut aluminum profile plate will be transported out of the workbench through the rubber roller for recycling, so as to realize the cyclic up and down feeding of the aluminum profile plate and improve the cutting and preparation efficiency of the aluminum profile for doors and windows.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners. Embodiment

[0023] As Figures 1 to 10 shown, a door and window aluminum profile cutting device according to an embodiment of the present invention includes a workbench 1, a U-shaped support frame 2 is installed on one side of the workbench 1, a servo push rod 3 is installed at the upper end of the U-shaped support frame 2, and the piston rod end of the servo push rod 3 penetrates through the U-shaped support frame 2 and is fixedly connected to a mounting bracket 8. A blanking knife 9 is installed in the inner cavity of the mounting bracket 8, and an intermittent conveying assembly 4 is installed on one side of the mounting bracket 8; And the intermittent conveying assembly 4 includes a mounting plate 41 inserted and installed on one side of the mounting bracket 8. One end of the mounting plate 41 is installed with a connecting frame 14. Two rotating shafts 44 are rotatably connected to one ends of the mounting plate 41 and the connecting frame 14, and two telescopic rods 42 are fixedly connected to one ends of the two rotating shafts 44. A rubber roller 47 is rotatably connected between the telescopic rods 42; The rubber roller 47 is made of anti-slip rubber. During the process of the mounting bracket 8 driving the blanking knife 9 to cut the aluminum profile plate, it can drive the mounting plate 41 and the connecting frame 14 to move synchronously, so that the mounting plate 41 and the connecting frame 14 drive the rubber roller 47 to press and fix the aluminum profile plate. During the process of the mounting bracket 8 driving the blanking knife 9 to reset, it can drive the rubber roller 47 to push the cut aluminum profile plate for blanking and the aluminum profile plate to be cut for loading.

[0024] Specifically, in the prior art, the aluminum profile plate is usually placed on the workbench, and the size of the aluminum profile plate to be cut is adjusted. Then, the step punching equipment is started to drive the cutting knife to cut the aluminum profile plate. After the aluminum profile plate is cut, it is necessary to first recycle the cut aluminum profile plate, and then adjust the aluminum profile plate again to adjust the cutting position. However, this cutting method is not only cumbersome for loading and unloading and affects the cutting efficiency of the aluminum profile plate, but also if the two ends of the aluminum profile plate are not pressed and fixed during cutting, the cut material is likely to bounce up after step punching cutting, posing a safety hazard to the surrounding operators; In the present invention, the aluminum sheet is conveyed onto the workbench 1, and the cutting size of the aluminum sheet is adjusted according to the cutting requirements. Then, the servo push rod 3 is started to drive the mounting frame 8 to move downward, and the mounting frame 8 drives the punching knife 9 to move downward. At the same time, the mounting frame 8 drives the mounting plate 41 and the connecting frame 14 to move synchronously, and then drives the telescopic rod 42 to move downward. The telescopic rod 42 rotates in the inner cavity of the rotating groove 43 by using the rotating shaft 44, and at the same time, the aluminum sheet on the workbench 1 is pressed and fixed by the rubber roller 47, which can ensure that during the cutting process of the aluminum sheet, the cut part of the aluminum sheet does not bounce up to cause potential safety hazards. After the aluminum sheet is cut, the servo push rod 3 drives the mounting frame 8 to move upward, and at the same time, the mounting frame 8 drives the mounting plate 41 and the connecting frame 14 to move upward, and then drives the telescopic rod 42 to move downward. During the upward movement of the telescopic rod 42, it will drive the rotating shaft 44 to rotate and drive the telescopic rod 42 to rotate and reset. At the same time, the telescopic rod 42 drives the rubber roller 47 to rotate synchronously. The rubber roller 47 is made of anti-slip rubber. Therefore, when the telescopic rod 42 drives the rubber roller 47 to rotate and reset, the rubber roller 47 will drive the aluminum sheet to be conveyed under the U-shaped support frame 2, and the rubber roller 47 at the connecting frame 14 will drive the cut aluminum sheet to slide out of the workbench 1 for recycling, thereby realizing the unloading and recycling of the aluminum sheet and pushing the aluminum sheet to be cut for loading, thus solving the above problems.

[0025] As Figures 3 to 7 and Figure 9 shown, rotating grooves 43 are respectively formed at one ends of the mounting plate 41 and the connecting frame 14. The rotating shaft 44 is rotatably connected to the inner cavity of the rotating groove 43. A fixing disk 45 is fixedly connected to the outside of the inner cavity of the rotating groove 43 of the rotating shaft 44. A torsion spring 46 is fixedly connected to one side of the fixing disk 45, and one end of the torsion spring 46 is fixedly connected to the inner wall of the rotating groove 43.

[0026] As Figures 3 to 7 and Figure 9 shown, one end of the telescopic rod 42 is rotatably connected to the rubber roller 47, and a ratchet 48 is installed outside the inner cavity of the rubber roller 47 at one end of the telescopic rod 42. The telescopic rod 42 can be adjusted in length according to the need for conveying the aluminum sheet.

[0027] Specifically, when the driving mounting plate 41 and the connecting frame 14 move downward, the telescopic rod 42 is driven to move downward by the mounting plate 41 and the connecting frame 14. At the same time, the telescopic rod 42 drives the rubber roller 47 to move downward, and the rubber roller 47 is pressed against the aluminum plate. Then, as the mounting plate 41 and the connecting frame 14 continue to move downward, the telescopic rod 42 drives the rubber roller 47 to rotate on the surface of the aluminum plate. At the same time, the telescopic rod 42 drives the rotating shaft 44 to rotate, which in turn drives the fixed disk 45 to rotate and drives the torsion spring 46 to twist. Then, the torsion of the torsion spring 46 is used to twist the fixed disk 45 to drive the rotating shaft 44. At the same time, the rotating shaft 44 drives the telescopic rod 42 and the rubber roller 47 to press and fix the aluminum plate, thereby ensuring the stability during the cutting process of the aluminum plate and avoiding the aluminum plate being subjected to the shearing force of the punching knife 9 during cutting. If the two ends are not pressed and fixed, the aluminum plate lacks restraint in the force direction. Under the combined action of the shearing force and the internal stress of the aluminum plate, uneven plastic deformation will occur in the local area, which will lead to the warping of the cutting edge of the aluminum plate. After the cutting of the aluminum plate is completed, the telescopic rod 42 is driven to move upward by driving the mounting plate 41 and the connecting frame 14. At the same time, the telescopic rod 42 drives the rubber roller 47 to move downward. During the upward movement of the telescopic rod 42, the torsion spring 46 is used to twist the fixed disk 45 to rotate, which in turn drives the rotating shaft 44 to rotate, and then drives the telescopic rod 42 and the rubber roller 47 to rotate. However, the rubber roller 47 is difficult to rotate due to the influence of the ratchet 48. Therefore, when the telescopic rod 42 moves upward, the telescopic rod 42 will rotate and reset, and at the same time drive the rubber roller 47 to rotate and reset, and use the rubber roller 47 to push the aluminum plate to be conveyed under the U-shaped support frame 2. The cut aluminum plate will be conveyed out of the workbench 1 through the rubber roller 47 for recycling, thus solving the problem that the existing aluminum profile cutting device for doors and windows has a low cutting efficiency when cutting aluminum plates. Because usually the operator pushes the aluminum plate for feeding, not only the operation is cumbersome, but also after cutting, the cut aluminum plate needs to be recycled, and then the aluminum plate is pushed again for feeding for secondary cutting.

[0028] As Figure 1 、 Figure 4 and Figure 6 shown, a pressing component 6 is arranged inside the upper end of the mounting plate 41, and the pressing component 6 is used to press and fix the aluminum plate to increase the stability and accuracy during the cutting of the aluminum plate. T-shaped sliding columns 7 are fixedly connected to both sides of the upper end of the mounting frame 8, and the T-shaped sliding columns 7 are slidably connected inside the U-shaped support frame 2.

[0029] As Figure 1 、 Figure 4 and Figure 6As shown, the pressing assembly 6 includes a plurality of fixed cylinders 61 installed inside the upper end of the mounting plate 41, and a first spring 62 is installed inside the cavities of the plurality of fixed cylinders 61. One end of the first spring 62 is fixedly connected to a T-shaped sliding rod 63, and one end of the T-shaped sliding rod 63 is installed with a pressing plate 64.

[0030] As Figure 3 , Figure 8 and Figure 9 As shown, turning slots 10 are formed on both sides of the blanking knife 9, and a grinding piece 11 is rotatably connected inside the turning slots 10.

[0031] Specifically, when driving the mounting plate 41 and the connecting frame 14 to move downward, the fixed cylinders 61 are driven to move downward through the mounting plate 41 and the connecting frame 14. At the same time, the fixed cylinders 61 drive the T-shaped sliding rods 63 to move downward, and then drive the pressing plate 64 to move downward to press and fix the aluminum plate on the workbench 1. As the mounting plate 41 and the connecting frame 14 continue to move downward, the pressing plate 64 will push the T-shaped sliding rod 63 to move upward, and the T-shaped sliding rod 63 will squeeze the first spring 62 and slide inside the fixed cylinder 61. Then, the blanking knife 9 cuts the aluminum plate on the workbench 1. When the blanking knife 9 cuts the aluminum plate, the blanking knife 9 will drive the grinding piece 11 to contact above the cutting opening of the aluminum plate. At the same time, the grinding piece 11 moves with the blanking knife 9 to grind the cutting opening of the aluminum plate. After the aluminum plate is cut, by driving the blanking knife 9 to move upward to reset, the blanking knife 9 will drive the grinding piece 11 to contact below the cutting opening of the aluminum plate, and then grind the lower part of the cutting opening of the aluminum plate, thus solving the problem that when the existing door and window aluminum cutting device processes and prepares door and window aluminum metal parts, if the cutting opening of the aluminum plate is not ground after cutting the aluminum plate, it is easy to scratch the hands of the operator during recycling, and when bending and manufacturing aluminum rods later, the aluminum plate still needs to be ground, which greatly affects the production and processing efficiency of doors and windows. Embodiment

[0032] As Figures 3 to 7 and Figure 9 As shown, through slots 15 are formed at both ends of the U-shaped support frame 2. Receiving slots 16 are formed on both inner walls of the through slots 15. A second spring 17 is fixedly connected to the bottom of the inner cavity of the receiving slot 16. A support column 19 is fixedly connected inside the through slot 15. Two sliders 18 are slidably connected to the outside of the support column 19. One end of the second spring 17 is fixedly connected to the slider 18.

[0033] As Figures 3 to 7 and Figure 9As shown, two grinding rollers 20 are rotatably connected between the sliders 18, and a layer of ceramic particles is provided on the outside of the two grinding rollers 20 for grinding the cutting edge and the blade surface of the blanking knife 9. A cutting groove 12 is formed on one side of the upper end surface of the workbench 1, and the two grinding rollers 20 are slidably connected in the inner cavity of the cutting groove 12. The cutting groove 12 is used to guide the recovery of waste burrs and other particles generated by the cutting of the aluminum plate. A collection box 13 is rotatably connected to the lower end surface of the workbench 1 below the cutting groove 12.

[0034] Specifically, when driving the blanking knife 9 to move downward, the blanking knife 9 will cut the aluminum plate. At the same time, the blanking knife 9 is inserted between the two grinding rollers 20 and squeezes the two grinding rollers 20 to move away from each other. Moreover, the two grinding rollers 20 drive the sliders 18 to slide outside the support columns 19, and at the same time squeeze the second spring 17 into the storage groove 16. Then, the return spring force of the second spring 17 is used to bounce the sliders 18 to move closer to each other, and the sliders 18 drive the two grinding rollers 20 to move closer to each other, so that the grinding rollers 20 fit more closely with the blanking knife 9. And a layer of ceramic particles is provided on the outside of the grinding rollers 20, so that the ceramic particles can be used to grind the cutting edge and the blade surface of the blanking knife 9, improve the sharpness of the blanking knife 9, and increase the cutting efficiency. The waste burr particles generated by grinding the aluminum plate will fall into the cutting groove 12 and fall into the collection box 13 through the blanking knife 9 for collection. Thus, it solves the problem that when the existing aluminum profile cutting device for doors and windows cuts the aluminum plate, if the cutting edge and the blade surface of the cutting knife are not ground, and the aluminum plate is cut through the step punching cycle, the cutting knife is severely worn. After long-term operation, the cutting edge of the cutting knife is worn, which will cause the cut edge of the aluminum plate to have warping and burrs when cutting the subsequent aluminum plate, affecting the preparation of the subsequent aluminum rods for doors and windows, and also posing a safety hazard to the operators during recycling.

[0035] As Figure 1 、 Figure 2 and Figure 10 As shown in, a groove 21 is symmetrically arranged on one side of the upper end surface of the workbench 1. A limiting component 5 is arranged in the inner cavity of the groove 21. The limiting component 5 includes a fixing rod 58 slidably connected in the inner cavity of the groove 21. A plurality of limiting pulleys 59 are evenly rotatably connected to the upper end of the fixing rod 58. One side of the fixing rod 58 is rotatably connected with a plurality of rotating rollers 57, and the plurality of rotating rollers 57 are slidably connected inside the workbench 1.

[0036] As Figure 1 、 Figure 2 and Figure 10As shown in the figure, a servo motor 56 is arranged inside the workbench 1. A driving bevel gear 53 is fixedly connected to the output shaft end of the servo motor 56. The driving bevel gear 53 is meshed and connected with a driven bevel gear 54. A bidirectional threaded rod 52 is fixedly connected inside the driven bevel gear 54. A threaded sleeve 51 is threadedly connected to the outside of the bidirectional threaded rod 52. A rotating sleeve 55 is rotatably connected to the outside of the threaded sleeve 51. One end of the threaded sleeve 51 is fixedly connected to a fixed rod 58.

[0037] Specifically, when cutting different aluminum plates to prepare aluminum rods for doors and windows, the servo motor 56 is started to drive the driving bevel gear 53 to rotate, and the driving bevel gear 53 meshes and drives the driven bevel gear 54 to rotate, thereby driving the bidirectional threaded rod 52 to rotate. At the same time, the bidirectional threaded rod 52 threadedly drives the threaded sleeve 51 to slide out of the workbench 1, further driving the fixed rod 58 to move synchronously. Then the fixed rod 58 drives the rotating roller 57 to slide out of the inside of the workbench 1 for adjusting the width limit, so as to be able to limit according to different aluminum plates, so as to ensure the conveying stability of the aluminum plates and avoid problems such as deviation during the conveying, cutting and processing of the aluminum plates, resulting in problems with the cutting accuracy.

[0038] Working principle: When driving the mounting plate 41 and the connecting frame 14 to move downward, the mounting plate 41 and the connecting frame 14 drive the telescopic rod 42 to move downward. At the same time, the telescopic rod 42 drives the rubber roller 47 to move downward, and the rubber roller 47 is pressed against the aluminum plate. Then, as the mounting plate 41 and the connecting frame 14 continue to move downward, the telescopic rod 42 will drive the rubber roller 47 to rotate on the surface of the aluminum plate. At the same time, the telescopic rod 42 drives the rotating shaft 44 to rotate, thereby driving the fixed disk 45 to rotate and driving the torsion spring 46 to twist. Then, the torsion of the torsion spring 46 is used to twist the fixed disk 45 to drive the rotating shaft 44. At the same time, the rotating shaft 44 drives the telescopic rod 42 and the rubber roller 47 to press and fix the aluminum plate, so as to ensure the stability during the cutting of the aluminum plate and avoid the aluminum plate being affected by the shearing force of the punching knife 9 during the cutting of the aluminum plate. If the two ends are not pressed and fixed, the aluminum plate lacks restraint in the force direction. Under the combined action of the shearing force and the internal stress of the aluminum plate, uneven plastic deformation will occur in the local area, resulting in the situation of warping at the cutting place of the aluminum plate. After the aluminum plate is cut, the mounting plate 41 and the connecting frame 14 are driven to drive the telescopic rod 42 to move upward. At the same time, the telescopic rod 42 drives the rubber roller 47 to move downward. During the upward movement of the telescopic rod 42, the torsion spring 46 is used to twist the fixed disk 45 to rotate, driving the rotating shaft 44 to rotate at the same time, and then driving the telescopic rod 42 and the rubber roller 47 to rotate. The rubber roller 47 is difficult to rotate due to the influence of the ratchet 48. Therefore, when the telescopic rod 42 moves upward, the telescopic rod 42 will rotate and reset, driving the rubber roller 47 to rotate and reset at the same time, and using the rubber roller 47 to push the aluminum plate to be conveyed below the U-shaped support frame 2. The cut aluminum plate will be conveyed out of the workbench 1 through the rubber roller 47 for recycling; When the driving installation plate 41 and the connecting frame 14 move downward, the fixing cylinder 61 is driven to move downward by the installation plate 41 and the connecting frame 14. At the same time, the fixing cylinder 61 drives the T-shaped slide bar 63 to move downward, and then drives the pressing plate 64 to move downward to press and fix the aluminum plate on the workbench 1. As the installation plate 41 and the connecting frame 14 continue to move downward, the pressing plate 64 will push the T-shaped slide bar 63 to move upward, and the T-shaped slide bar 63 will squeeze the first spring 62 and slide in the inner cavity of the fixing cylinder 61. Then, the punching knife 9 cuts the aluminum plate on the workbench 1. When the punching knife 9 cuts the aluminum plate, the punching knife 9 will drive the grinding piece 11 to contact above the cutting opening of the aluminum plate. At the same time, the grinding piece 11 moves with the punching knife 9 to grind the cutting opening of the aluminum plate. After the aluminum plate is cut, by driving the punching knife 9 to move upward to reset, the punching knife 9 will drive the grinding piece 11 to contact below the cutting opening of the aluminum plate, and then grind the lower part of the cutting opening of the aluminum plate; When the driving punching knife 9 moves downward, the punching knife 9 will cut the aluminum plate. At the same time, the punching knife 9 is inserted between the two grinding rollers 20, and squeezes the two grinding rollers 20 to move away from each other. Moreover, the two grinding rollers 20 drive the slider 18 to slide outside the support column 19, and at the same time squeeze the second spring 17 into the receiving groove 16. Then, the resilience of the second spring 17 is used to bounce the slider 18 to move closer to each other, and the slider 18 drives the two grinding rollers 20 to move closer to each other, so that the grinding rollers 20 fit more closely with the punching knife 9. There is a layer of ceramic particles on the outside of the grinding roller 20, so that the ceramic particles can be used to grind the cutting edge and the blade surface of the punching knife 9, improve the sharpness of the punching knife 9, and increase the cutting efficiency. The waste burr particles generated by grinding the aluminum plate will fall into the cutting groove 12 and fall into the collection box 13 through the punching knife 9 for collection, thus completing the preparation work of the door and window aluminum materials.
