Description

Technical Field

[0001] The invention belongs to the technical field of aluminum material cutting, in particular to a door and window aluminum material cutting device. Background Art

[0002] Aluminum doors and windows refer to door and window products made of aluminum materials. The doors and windows are composed of a frame composed of four aluminum rods. They are beautiful, sealed, and strong, and are widely used in the field of construction engineering. The manufacturing of aluminum rods for doors and windows usually uses a cutting equipment with a step punching action to cut the aluminum plate, and then uses a bending device to bend the cut aluminum plate to prepare the aluminum rod. At the same time, the aluminum rods are spliced ​​and welded by welding equipment to complete the production and processing of doors and windows.

[0003] A patent with publication number CN118893242A discloses a door and window aluminum material cutting device. The device places the aluminum material on a mounting base, and then a driving device drives the cutting knife to move downward to cut the aluminum material. When the driving device drives the cutting knife to reset, the driving device drives the belt to rotate through the transmission device, and the belt pushes the aluminum material forward through the pushing device to feed the next cutting. Then, the size of the aluminum cutting is adjusted by adjusting the ratio between the driving device and the adjusting transmission device through the adjusting device, and the tensioning device keeps the belt tensioned.

[0004] The above scheme still has some problems in actual application. Usually, the aluminum plate is placed on the workbench, and the size of the aluminum plate to be cut is adjusted. Then, the nibbling equipment is started to drive the cutting knife to cut the aluminum plate. After the cutting of the aluminum plate is completed, the cut aluminum plate must be recycled first, and then the aluminum plate is adjusted again to adjust the cutting position, and the nibbling equipment is started again to cut it. This cutting method is not only difficult to achieve cyclic cutting of the aluminum plate, but also if the two ends of the aluminum plate are not pressed and fixed during cutting, the cut material of the aluminum plate is prone to bounce up after the nibbling cutting, posing a safety hazard to the surrounding workers.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0040] like Figures 1 to 10 As shown, an aluminum material cutting device for doors and windows according to an embodiment of the present invention comprises a workbench 1, a U-shaped support frame 2 is mounted on one side of the workbench 1, a servo push rod 3 is mounted on the upper end of the U-shaped support frame 2, and the piston rod end of the servo push rod 3 passes through the U-shaped support frame 2 and is fixedly connected to a mounting frame 8, a punching knife 9 is mounted in the inner cavity of the mounting frame 8, and an intermittent conveying assembly 4 is mounted on one side of the mounting frame 8;

[0041] The intermittent conveying assembly 4 includes a mounting plate 41 that is plugged into one side of the mounting frame 8. A connecting frame 14 is mounted on one end of the mounting plate 41. Two rotating shafts 44 are rotatably connected to one end of each of the mounting plate 41 and the connecting frame 14. Telescopic rods 42 are fixed to one end of each of the two rotating shafts 44. A rubber roller 47 is rotatably connected between the telescopic rods 42.

[0042] The rubber roller 47 is made of non-slip rubber. When the mounting frame 8 drives the punching knife 9 to cut the aluminum 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 plate. When the mounting frame 8 drives the punching knife 9 to reset, it also drives the rubber roller 47 to push the cut aluminum plate for unloading and the aluminum plate to be cut for loading.

[0043] Specifically, in the prior art, an aluminum plate is usually placed on a workbench, the size of the aluminum plate to be cut is adjusted, and then the nibbling equipment is started to drive the cutting knife to cut the aluminum plate. After the aluminum plate is cut, the cut aluminum plate needs to be recovered first, and then the aluminum plate needs to be adjusted again to adjust the cutting position. However, this cutting method is not only cumbersome to load and unload materials and affects the cutting efficiency of the aluminum plate, but also, if the two ends of the aluminum plate are not pressed and fixed during cutting, the cut material of the aluminum plate is prone to bounce after the nibbling cutting, posing a safety hazard to surrounding workers.

[0044] The present invention conveys the aluminum plate to the workbench 1, adjusts the cutting size of the aluminum plate according to the cutting needs, and then starts the servo push rod 3 to drive the mounting frame 8 to move downward, and the mounting frame 8 drives the punching knife 9 to move downward, and 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, and the telescopic rod 42 rotates in the inner cavity of the rotating groove 43 by the rotating shaft 44, and at the same time uses the rubber roller 47 to press and fix the aluminum plate on the workbench 1, which can ensure that the cut part of the aluminum plate will not bounce up and cause safety hazards during the cutting process of the aluminum plate. After the cutting of the aluminum plate is completed, the mounting frame 8 is driven to move upward by the servo push rod 3, and the mounting frame 8 is installed. 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, the rotating shaft 44 will be driven to rotate, and the telescopic rod 42 will be driven 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 non-slip rubber. When the telescopic rod 42 drives the rubber roller 47 to rotate and reset, the rubber roller 47 will be used to drive the aluminum plate to be transported to the bottom of the U-shaped support frame 2, and the rubber roller 47 at the connecting frame 14 will drive the cut aluminum plate to slide out of the workbench 1 for recycling, thereby realizing the return and recycling of the aluminum plate and pushing the aluminum plate to be cut for loading, thereby solving the above-mentioned problem.

[0045] like Figures 3 to 7 and Figure 9 As shown, a rotation groove 43 is provided in one end of the mounting plate 41 and the connecting frame 14, and a rotating shaft 44 is rotatably connected in the inner cavity of the rotation groove 43. The rotating shaft 44 is located outside the inner cavity of the rotation groove 43 and is fixedly connected to a fixed plate 45. A torsion spring 46 is fixedly connected to one side of the fixed plate 45, and one end of the torsion spring 46 is fixedly connected to the inner wall of the rotation groove 43.

[0046] like Figures 3 to 7 and Figure 9 As shown, one end of the telescopic rod 42 is rotatably connected to the rubber roller 47, and a ratchet 48 is installed on the outside of the inner cavity of the rubber roller 47 at one end of the telescopic rod 42. The length of the telescopic rod 42 can be adjusted according to the needs of conveying the aluminum plate.

[0047] Specifically, when the mounting plate 41 and the connecting frame 14 are driven to move downward, the telescopic rod 42 is driven downward by the mounting plate 41 and the connecting frame 14, and 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, and then drives the fixed plate 45 to rotate, and drives the torsion spring 46 to twist, and then The torsion force 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 of the aluminum plate during the cutting process and preventing the aluminum plate from being subjected to the shear force of the punching knife 9 during cutting. If the two ends are not pressed and fixed, the aluminum plate lacks constraints in the direction of force. Under the combined action of the shear 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 aluminum plate at the cutting position. 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, and 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 plate 45 to rotate, and at the same time, the rotating shaft 44 is driven to rotate, and then the telescopic rod 42 and the rubber roller 47 are driven to rotate. The rubber roller 47 is affected by the ratchet 48 and is difficult to rotate. Then, 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. The aluminum plate is reset and the rubber roller 47 is used to push the aluminum plate to the bottom of the U-shaped support frame 2 for transportation. The cut aluminum plate will be transported out of the workbench 1 by the rubber roller 47 for recycling, thereby solving the problem that when the existing aluminum cutting device for doors and windows cuts the aluminum plate, the operator usually pushes the aluminum plate raw material, which is not only cumbersome to operate, but also needs to recycle the cut aluminum plate after the cutting is completed, and then push the aluminum plate raw material again for secondary cutting, thereby greatly reducing the cutting efficiency of the aluminum plate.

[0048] like Figure 1 、 Figure 4 and Figure 6 As shown, a pressing assembly 6 is provided inside the upper end of the mounting plate 41, and the pressing assembly 6 is used to press and fix the aluminum plate to increase the stability and accuracy when cutting the aluminum plate. T-shaped sliding columns 7 are fixed on 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.

[0049] like Figure 1 、 Figure 4 and Figure 6As shown, the pressing assembly 6 includes multiple fixed cylinders 61 installed in the upper end of the mounting plate 41, and the inner cavities of the multiple fixed cylinders 61 are installed with first springs 62, one end of the first spring 62 is fixedly connected to a T-shaped slide rod 63, and one end of the T-shaped slide rod 63 is installed with a pressing plate 64.

[0050] like Figure 3 、 Figure 8 and Figure 9 As shown, both sides of the punching knife 9 are provided with a turning groove 10, and the inner cavity of the turning groove 10 is rotatably connected to a grinding plate 11.

[0051] Specifically, when the mounting plate 41 and the connecting frame 14 are driven to move downward, the fixing cylinder 61 is driven downward by the mounting plate 41 and the connecting frame 14, and 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, and as the mounting 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 make the T-shaped slide bar 63 squeeze the first spring 62 to slide in the inner cavity of the fixing cylinder 61, and then the punching knife 9 cuts the aluminum plate on the workbench 1, and when the punching knife 9 cuts the aluminum plate, the punching knife 9 will drive the grinding sheet 11 to contact the upper part of the cutting opening of the aluminum plate At the same time, the grinding sheet 11 moves with the punching knife 9 to grind the cutting edge of the aluminum plate. After the cutting of the aluminum plate is completed, the punching knife 9 is driven to move upward and reset, and the punching knife 9 will drive the grinding sheet 11 to contact the bottom of the cutting edge of the aluminum plate, and then grind the bottom of the cutting edge of the aluminum plate, thereby solving the problem that the existing aluminum cutting device for doors and windows is used for processing and preparing aluminum metal parts for doors and windows. After the cutting of the aluminum plate is completed, if the cutting edge of the aluminum plate is not polished, the operator may easily cause scratches on his hands when recycling it, and the aluminum plate needs to be polished during the subsequent bending to make aluminum rods, which greatly affects the production and processing efficiency of doors and windows. Example

[0052] like Figures 3 to 7 and Figure 9 As shown, both ends of the U-shaped support frame 2 are provided with through grooves 15, and both walls of the inner cavity of the through groove 15 are provided with receiving grooves 16. A second spring 17 is fixedly connected to the bottom of the inner cavity of the receiving groove 16, and a support column 19 is fixedly connected to the inner cavity of the through groove 15. Two sliders 18 are slidably connected to the outside of the support column 19, and one end of the second spring 17 is fixedly connected to the slider 18.

[0053] like 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 blade and the blade surface of the punching knife 9. A cutting groove 12 is provided 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 cutting aluminum plates. The lower end surface of the workbench 1 is located below the cutting groove 12 and is rotatably connected to a collection box 13.

[0054] Specifically, when the punching knife 9 is driven to move downward, the punching knife 9 will cut the aluminum plate, and 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, and 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 storage groove 16, and then use the rebound force of the second spring 17 to bounce the slider 18 to move closer to each other, and make the slider 18 drive the two grinding rollers 20 to move closer to each other, thereby making the grinding roller 20 and the punching knife 9 fit more closely, and a layer of ceramic particles is provided on the outside of the grinding roller 20, so that the ceramic particles can be used to resist the punching knife 9. The blade and the blade surface are polished to improve the sharpness of the punching knife 9 and increase the cutting efficiency. The waste burrs generated by polishing the aluminum plate will fall into the cutting groove 12 and fall into the collection box 13 through the punching knife 9 for collection, thereby solving the problem that when the existing door and window aluminum cutting device is used to cut the aluminum plate, if the blade and the blade surface of the cutting knife are not polished, and the aluminum plate is cut through the step punching cycle, the cutting knife will be worn out. If the cutting knife blade is worn out for a long time, the cut edge of the aluminum plate will warp and have barbs when cutting subsequent aluminum plates, affecting the subsequent preparation of door and window aluminum rods, and also causing safety hazards to the operation work during recycling.

[0055] like Figure 1 、 Figure 2 and Figure 10 As shown, a groove 21 is symmetrically provided on one side of the upper end surface of the workbench 1, a limiting component 5 is provided in the inner cavity of the groove 21, and the limiting component 5 includes a fixed rod 58 slidably connected in the inner cavity of the groove 21, and a plurality of limiting pulleys 59 are evenly connected to the upper end of the fixed rod 58 for rotation, and a plurality of rotating rollers 57 are rotatably connected on one side of the fixed rod 58, and the plurality of rotating rollers 57 are slidably connected inside the workbench 1.

[0056] like Figure 1 、 Figure 2 and Figure 10As shown, a servo motor 56 is provided in the inner cavity of the workbench 1, and the output shaft end of the servo motor 56 is fixedly connected to a transmission bevel gear 53, and the transmission bevel gear 53 is meshedly connected to a driven bevel gear 54, and a bidirectional threaded rod 52 is fixed inside the driven bevel gear 54, and the bidirectional threaded rod 52 is externally threadedly connected to a threaded sleeve 51, and the threaded sleeve 51 is externally rotatably connected to a rotating sleeve 55, and one end of the threaded sleeve 51 is fixed to a fixed rod 58.

[0057] Specifically, when different aluminum plates are cut to prepare aluminum rods for doors and windows, the servo motor 56 is started to drive the transmission bevel gear 53 to rotate, and the transmission bevel gear 53 is engaged with 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 threaded transmission thread sleeve 51 slides out of the workbench 1, thereby driving the fixed rod 58 to move synchronously, and then the fixed rod 58 drives the rotating roller 57 to slide out of the workbench 1 to adjust the width limit, and then it can be limited according to different aluminum plates to ensure the transportation stability of the aluminum plates, and avoid the deviation of the aluminum plates during the transportation and cutting process, which causes problems with cutting accuracy.

[0058] The working principle is that when the mounting plate 41 and the connecting frame 14 are driven to move downward, the telescopic rod 42 is driven downward by the mounting plate 41 and the connecting frame 14, and the telescopic rod 42 drives the rubber roller 47 to move downward, and makes the rubber roller 47 fit and press 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, and then drives the fixed plate 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 plate 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 of the aluminum plate during the cutting process, and preventing the aluminum plate from being subjected to the shear force of the punching knife 9 during cutting. If the two ends are not pressed and fixed, the aluminum plate lacks a certain pressure in the direction of force. The elastic member 42 of the U-shaped support frame 2 is pushed to the bottom of the U-shaped support frame 2 for conveying, and the cut aluminum plate is transported out of the workbench 1 for recycling.

[0059] When the mounting plate 41 and the connecting frame 14 are driven to move downward, the fixing cylinder 61 is driven downward by the mounting plate 41 and the connecting frame 14, and 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 mounting plate 41 and the connecting frame 14 continue to move downward, the pressing plate 64 pushes the T-shaped slide bar 63 to move upward, and causes the T-shaped slide bar 63 to squeeze the first spring 62 and slide on the fixing cylinder 61. In the inner cavity, the punching knife 9 then cuts the aluminum plate on the workbench 1. When the punching knife 9 cuts the aluminum plate, the punching knife 9 drives the grinding sheet 11 to contact the upper part of the cutting opening of the aluminum plate. At the same time, the grinding sheet 11 grinds the cutting opening of the aluminum plate as the punching knife 9 moves. After the cutting of the aluminum plate is completed, the punching knife 9 is driven to move upward and reset. The punching knife 9 drives the grinding sheet 11 to contact the lower part of the cutting opening of the aluminum plate, and then grinds the lower part of the cutting opening of the aluminum plate.

[0060] When the punching knife 9 is driven to move 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. 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 storage groove 16. Then, the rebound force 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, thereby making the grinding roller 20 fit more closely with the punching knife 9. A layer of ceramic particles is provided on the outside of the grinding roller 20, so that the ceramic particles can be used to grind the blade edge and blade surface of the punching knife 9, thereby improving the sharpness of the punching knife 9 and increasing the cutting efficiency. The waste burrs 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, thereby completing the preparation of aluminum materials for doors and windows.
