Description

Technical Field

[0001] This invention relates to the field of door and window profile processing technology, specifically to a highly stable cutting device and method for door and window profile materials. Background Technology

[0002] Window and door profiles are the core skeletal materials that make up the window and door frames. They are mainly used to support the glass, hardware, and sealing systems, directly affecting the strength, airtightness, watertightness, sound insulation, heat insulation performance, and service life of the windows and doors. Mainstream products are made of aluminum alloy, using an extrusion molding process to create a hollow, multi-cavity structure, effectively reducing heat conduction and improving wind pressure resistance.

[0003] After cutting aluminum profiles for doors and windows, burrs will be generated at the cut ends, which can easily scratch workers. Additional deburring is required, which is labor-intensive and resource-intensive. Moreover, the debris generated during cutting will accumulate on the workbench. After cutting and retracting the blade, the door and window profiles will move the debris to other positions on the workbench, which can cause subsequent door and window profiles to press on the debris, change the position of the profiles, and reduce the cutting accuracy of the profiles.

[0004] Therefore, based on the above problems, we have invented a highly stable cutting device and method for door and window profile materials. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-stability cutting device for door and window profile materials, comprising a worktable, support plates installed on both sides of the lower end of the worktable, a rotating plate rotatably mounted on the worktable, a rotating cylinder installed at the lower end of the rotating plate, a cutting component installed inside the rotating cylinder, a debris collection mechanism for collecting debris inside the rotating cylinder, a through-cutting groove provided on the rotating plate, the cutting groove matching the cutting component, a horizontal plate fixedly mounted above the worktable via a vertical plate, two fixing clamps provided below the horizontal plate, a moving mechanism for moving the fixing clamps provided on the horizontal plate, a rotating column rotatably mounted through the horizontal plate, a burr cleaning mechanism provided inside the rotating column, a rotating shaft rotatably mounted through the worktable and the horizontal plate, a lower synchronous gear and an upper synchronous gear coaxially mounted outside the rotating shaft, annular toothed grooves meshing with the lower synchronous gear and the upper synchronous gear respectively provided on the outer walls of the rotating cylinder and the rotating column, a synchronous motor mounted on the horizontal plate, the drive shaft of the synchronous motor coaxially mounted with the rotating shaft.

[0007] Furthermore, the debris collection mechanism includes two debris dropping platforms fixedly installed inside the rotating drum. The two debris dropping platforms are respectively placed on both sides of the cutting assembly. A debris collection box is installed at one end of each debris dropping platform. The debris collection box is installed through the rotating drum. A negative pressure suction tube is connected to the end of the debris collection box away from the debris dropping platform. A collection chamber is provided inside the debris collection box. An aggregation groove is provided at the upper end of the debris dropping platform. The aggregation groove is connected to the collection chamber.

[0008] Furthermore, the moving mechanism includes two telescopic cylinders respectively mounted on the upper end of the fixed clamp. The lower end of the horizontal plate is provided with two grooves, and a fixed screw is rotatably installed in each of the two grooves. A movable threaded block is threaded onto the external thread of the fixed screw. The movable threaded block is slidably installed in the groove. The upper ends of the two telescopic cylinders are respectively fixedly connected to the movable threaded blocks. A drive shaft is rotatably passed through the horizontal plate. The drive shaft and the two fixed screws are connected by a transmission mechanism. A moving motor is mounted on the outside of the horizontal plate. The drive shaft of the moving motor is coaxially mounted with the drive shaft.

[0009] Furthermore, the transmission mechanism includes a first pulley and a second pulley. The first pulley is coaxially mounted with the transmission shaft, and the second pulley is coaxially mounted with the fixing screw. The first pulley and the second pulley are connected by a synchronous belt drive.

[0010] Furthermore, the deburring mechanism includes a cleaning groove located at the lower end of the rotating column, a U-shaped plate inside the cleaning groove, a lifting mechanism for raising and lowering the U-shaped plate inside the cleaning groove, two deburring sanding belts inside the U-shaped plate, the deburring sanding belts being driven by two rotating rollers, both ends of the rotating rollers being rotatably mounted to the two arms of the U-shaped plate, one end of each of the two upper rotating rollers rotatably passing through the U-shaped plate and coaxially mounted with a transmission gear, the two transmission gears being meshed together, a rotating motor being mounted outside the U-shaped plate, the drive shaft of the rotating motor rotatably passing through the U-shaped plate and coaxially mounted with one of the deburring sanding belts.

[0011] Furthermore, the lifting mechanism includes a bidirectional screw rotatably mounted to the inner wall of the cleaning groove. Two lifting threaded blocks are threaded onto the external threads of the bidirectional screw, and both lifting threaded blocks are slidably connected to the cleaning groove. A deflection plate is rotatably mounted on the lower end of each lifting threaded block. A lifting plate is fixedly connected to the upper end of the U-shaped plate. The lifting plate is slidably mounted to the cleaning groove. The lower end of the deflection plate is rotatably mounted to the upper end of the lifting plate. A lifting motor is installed inside the cleaning groove, and the drive shaft of the lifting motor is coaxially mounted with the bidirectional screw.

[0012] Furthermore, the bottom of the collection tank is inclined.

[0013] A highly stable cutting method for door and window profile materials includes the following steps: S1. Fixing: Place the door and window profiles in a suitable position on the workbench and fix them with fixing clamps; S2. Cutting: Adjust the cutting angle of the cutting component to a suitable position, and then cut the door and window profiles using the cutting component. After cutting is completed, the cutting component is retracted. S3, Deburring: Move the two cut sections of the door and window profile to a suitable position, and then move the deburring sander down to a suitable position. At this time, move the door and window profile so that it comes into contact with the deburring sander. The deburring sander cleans the burrs of the door and window profile downwards. S4. Collection: The debris falls into the collection tank. An external negative pressure device sucks the debris from the collection tank and collects it into the collection chamber, thus completing the cutting and debris cleaning of the door and window profiles.

[0014] Compared with the prior art, the present invention provides a highly stable cutting device and method for door and window profile materials, which has the following beneficial effects: 1. Process integration to avoid secondary operations: After cutting, there is no need to transfer the profile to a separate deburring station. The profile position can be adjusted directly through the moving mechanism to drive the deburring belt to contact the cutting surface and complete the deburring simultaneously. This completely eliminates the need for additional deburring processes, significantly shortens the processing cycle, and reduces equipment investment and labor costs.

[0015] 2. Automated cleaning, replacing manual operation: The burr cleaning mechanism uses components such as lifting motor, bidirectional screw, and deflection plate to achieve precise lifting and positioning of U-shaped plate and deburring sanding belt. Then, the rotating motor drives the sanding belt to rotate, completing the automated cleaning of burrs. This completely replaces the traditional manual hand-held tool grinding method, which not only reduces the intensity of manual labor but also avoids the risk of scratches caused by manual operation, ensuring work safety.

[0016] 3. Real-time collection to block the displacement path of debris: The debris generated by the cutting component and the deburring belt falls directly into the collection grooves on both sides of the cutting component through the cutting groove. The bottom of the collection groove is designed with an inclination. Combined with the adsorption effect of the external negative pressure equipment, the debris is quickly guided into the collection chamber, avoiding the accumulation of debris on the worktable and preventing the debris from being displaced when the profile moves. This eliminates the interference of debris on the placement of the profile from the source, ensures the stable positioning of the profile, and significantly improves the cutting accuracy.

[0017] This application integrates cutting, deburring, and debris collection into a single design. This eliminates the need for additional deburring processes, significantly reduces labor and material costs, actively blocks debris interference, and ensures cutting accuracy, achieving streamlined processing, improved efficiency, and enhanced operational safety.

[0020] 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.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a highly stable cutting device and method for door and window profile materials.

[0022] like Figures 1-7As shown, a high-stability cutting device for door and window profiles includes a worktable 1, with support plates 2 installed on both sides of the lower end of the worktable 1. A rotating plate 4 is rotatably mounted on the worktable 1, and a rotating cylinder 3 is installed at the lower end of the rotating plate 4. A cutting component 6 is installed inside the rotating cylinder 3. It should be noted that the driving mechanism of the cutting component 6 is existing technology, and its details are not elaborated here. A debris collection mechanism 7 for collecting debris is provided inside the rotating cylinder 3. A cutting groove 5 is provided through the rotating plate 4, and the cutting groove 5 matches the cutting component 6. A vertical plate 4 is connected above the worktable 1. A horizontal plate 12 is fixedly installed. Two fixing clamps 29 are located below the horizontal plate 12. A moving mechanism 28 for moving the fixing clamps 29 is provided on the horizontal plate 12. It should be noted that the moving mechanism 28 includes two telescopic cylinders 30 respectively installed on the upper ends of the fixing clamps 29. Two grooves 31 are provided at the lower end of the horizontal plate 12. A fixing screw 32 is rotatably installed in each of the two grooves 31. A movable threaded block 38 is threaded onto the external thread of the fixing screw 32. The movable threaded block 38 is slidably installed with the groove 31. The two telescopic cylinders 30... The upper ends are fixedly connected to the movable threaded blocks 38. A drive shaft 33 is rotatably mounted on the horizontal plate 12. The drive shaft 33 is connected to the two fixed screws 32 through a transmission mechanism 34. It should be noted that the transmission mechanism 34 includes a first pulley 36 and a second pulley 37. The first pulley 36 is coaxially mounted with the drive shaft 33, and the second pulley 37 is coaxially mounted with the fixed screws 32. The first pulley 36 and the second pulley 37 are connected by a synchronous belt. A movable motor 35 is mounted on the outside of the horizontal plate 12. The drive shaft and transmission shaft 33 are coaxially mounted. A rotating column 13 is rotatably mounted on the horizontal plate 12. A burr cleaning mechanism 17 is provided inside the rotating column 13. A rotating shaft 41 is rotatably mounted between the worktable 1 and the horizontal plate 12. A lower synchronous gear 14 and an upper synchronous gear 15 are coaxially mounted on the outside of the rotating shaft 41. The outer walls of the rotating cylinder 3 and the rotating column 13 are respectively provided with annular tooth grooves that mesh with the lower synchronous gear 14 and the upper synchronous gear 15. A synchronous motor 16 is mounted on the horizontal plate 12. The drive shaft of the synchronous motor 16 is coaxially mounted with the rotating shaft 41.

[0023] Through the above technical features: when it is necessary to move the door and window profiles, the drive shaft of the moving motor 35 drives the transmission shaft 33 to rotate, the transmission shaft 33 drives the two fixed screws 32 to rotate, the two fixed screws 32 drive the two moving threaded blocks 38 to move relative to each other, the two moving threaded blocks 38 drive the fixed clamps 29 to move through the telescopic cylinder 30, and the two fixed clamps 29 drive the door and window profiles on both sides to move relative to each other, which facilitates the subsequent grinding of the cut surfaces of the door and window profiles.

[0024] To collect debris, a debris collection mechanism 7 is provided. The debris collection mechanism 7 includes two debris drop platforms 8 fixedly installed inside the rotating drum 3. The two debris drop platforms 8 are respectively placed on both sides of the cutting assembly 6. A debris collection box 9 is installed at one end of the debris drop platform 8. The debris collection box 9 is installed through the rotating drum 3. The end of the debris collection box 9 away from the debris drop platform 8 is connected to a negative pressure suction pipe 10. It should be noted that the negative pressure suction pipe 10 is connected to an external negative pressure device, and a barrier net is set at the end of the negative pressure suction pipe 10 inside the debris collection box 9. The debris collection box 9 is provided with a collection chamber 11. The upper end of the debris drop platform 8 is provided with a gathering groove 39, which is connected to the collection chamber 11. It should be noted that the bottom of the gathering groove 39 is inclined.

[0025] Through the above technical features: when the cutting component 6 cuts the door and window profiles and generates debris, and when the deburring sander 26 grinds the door and window profiles and generates debris, the debris falls through the cutting groove 5 into the gathering grooves 39 on both sides of the cutting component 6. On the one hand, the debris slides down into the collection chamber 11 under the action of the slope of the gathering groove 39. On the other hand, the debris enters the collection chamber 11 for collection under the adsorption of the external negative pressure device. After the cutting is completed, the debris collection box 9 can be removed to clean the debris in the collection chamber 11. The collection and cleaning of debris is relatively convenient.

[0026] To remove burrs from the cut surfaces of door and window profiles, a burr removal mechanism 17 is provided. The burr removal mechanism 17 includes a cleaning groove 43 located at the lower end of a rotating column 13. A U-shaped plate 18 is located within the cleaning groove 43. A lifting mechanism 20 for raising and lowering the U-shaped plate 18 is also located within the cleaning groove 43. Notably, the lifting mechanism 20 includes a bidirectional screw 21 rotatably mounted to the inner wall of the cleaning groove 43. Two lifting threaded blocks 22 are threaded onto the external surface of the bidirectional screw 21. Both lifting threaded blocks 22 are slidably connected to the cleaning groove 43. A deflection plate 24 is rotatably mounted at the lower end of each lifting threaded block 22. A lifting plate 19 is fixedly connected to the upper end of the U-shaped plate 18. The lifting plate 19 is connected to the cleaning groove 43. The sliding installation is such that the lower end of the deflection plate 24 is rotatably installed with the upper end of the lifting plate 19. A lifting motor 23 is installed in the cleaning groove 43. The drive shaft of the lifting motor 23 is coaxially installed with the bidirectional screw 21. Two deburring sanding belts 26 are provided in the U-shaped plate 18. The deburring sanding belts 26 are driven by two rotating rollers 25. Both ends of the rotating rollers 25 are rotatably installed with the two arms of the U-shaped plate 18. One end of the two upper rotating rollers 25 rotatably passes through the U-shaped plate 18 and is coaxially installed with a transmission gear 27. The two transmission gears 27 are meshed and connected. A rotating motor 42 is installed outside the U-shaped plate 18. The drive shaft of the rotating motor 42 rotatably passes through the U-shaped plate 18 and is coaxially installed with one of the deburring sanding belts 26.

[0027] Through the above technical features: After cutting, the door and window profile is moved to a suitable position by the moving mechanism 28. The drive shaft of the lifting motor 23 drives the bidirectional screw 21 to rotate. The bidirectional screw 21 drives two lifting thread blocks 22 to move relative to each other. The lifting thread blocks 22 drive the lifting plate 19 to rise and fall through the deflection plate 24. The lifting plate 19 drives the U-shaped plate 18 to rise and fall until the suitable position is reached. At this time, the moving mechanism 28 moves in the opposite direction so that the cut surface of the door and window profile comes into contact with the deburring sanding belt 26. At this time, the drive shaft of the rotating motor 42 drives two rotating rollers 25 to rotate relative to each other. The rotating rollers 25 drive the deburring sanding belt 26 to rotate, so that the side of the deburring sanding belt 26 in contact with the cut surface moves downward, thereby cleaning the burrs on the cut surface downward and letting them fall into the collection groove 39 for collection. When cutting the door and window profile, the amount of debris on the workbench 1 is reduced, the impact of debris on the placement of the door and window profile is reduced, and the cutting accuracy of the door and window profile is improved.

[0028] A highly stable cutting method for door and window profile materials includes the following steps: S1. Fixing: Place the door and window profiles at a suitable position on the workbench 1 and fix the door and window profiles using the fixing clamps 29; S2. Cutting: Adjust the cutting angle of the cutting component 6 to a suitable position, and then cut the door and window profiles through the cutting component 6. After the cutting is completed, the cutting component 6 is retracted. S3, Deburring: Move the two cut door and window profiles to a suitable position, and then move the deburring sanding belt 26 down to a suitable position. At this time, move the door and window profiles so that they come into contact with the deburring sanding belt 26, and clean the burrs of the door and window profiles downward through the deburring sanding belt 26. S4. Collection: The debris that falls into the collection tank 39 is sucked up by an external negative pressure device and collected into the collection chamber 11, thus completing the cutting and debris removal of the door and window profiles. Working principle: Fixing door and window profiles: The telescopic cylinder 30 extends and retracts to raise and lower the fixing clamp 29 until it reaches the appropriate position, so that the fixing clamp 29 clamps and fixes the door and window profiles. Cutting of door and window profiles: The drive shaft of the synchronous motor 16 drives the rotating shaft 41 to rotate, the rotating shaft 41 drives the lower synchronous gear 14 and the upper synchronous gear 15 to rotate, the lower synchronous gear 14 drives the rotating cylinder 3 and the rotating plate 4 to rotate, and the upper synchronous gear 15 drives the rotating column 13 to rotate until the appropriate angle is reached. Then the cutting assembly 6 is driven to cut the door and window profiles. Deburring of door and window profiles: After cutting, the door and window profiles are moved to a suitable position by the moving mechanism 28. The drive shaft of the lifting motor 23 drives the bidirectional screw 21 to rotate. The bidirectional screw 21 drives two lifting thread blocks 22 to move relative to each other. The lifting thread blocks 22 drive the lifting plate 19 to rise and fall through the deflection plate 24. The lifting plate 19 drives the U-shaped plate 18 to rise and fall until the suitable position is reached. At this time, the moving mechanism 28 moves in the opposite direction so that the cut surface of the door and window profiles comes into contact with the deburring sanding belt 26. At this time, the drive shaft of the rotating motor 42 drives two rotating rollers 25 to rotate relative to each other. The rotating rollers 25 drive the deburring sanding belt 26 to rotate, so that the side of the deburring sanding belt 26 in contact with the cut surface moves downward, thereby cleaning the burrs on the cut surface downward and letting them fall into the collection groove 39 for collection. When cutting door and window profiles, the amount of debris on the workbench 1 is reduced, the impact of debris on the placement of door and window profiles is reduced, and the cutting accuracy of door and window profiles is improved. Debris collection: When the cutting component 6 produces debris from cutting the door and window profiles and the deburring sander 26 produces debris from grinding the door and window profiles, the debris falls through the cutting groove 5 into the gathering grooves 39 on both sides of the cutting component 6. On the one hand, the debris slides down into the collection chamber 11 under the action of the slope of the gathering groove 39. On the other hand, the debris enters the collection chamber 11 for collection under the adsorption of the external negative pressure device. After the cutting is completed, the debris collection box 9 can be removed to clean the debris in the collection chamber 11. The collection and cleaning of debris is relatively convenient.
