Description

Technical Field

[0001] The utility model relates to the technical field of blanking machines, and particularly relates to a protection mechanism for an aluminum alloy door and window blanking machine. Background Technique

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extrusion profiles as frames, stiles, and sashes, which are simply called aluminum doors and windows. During the production process of aluminum alloy doors and windows, blanking machines are required to cut aluminum alloy profiles.

[0003] When the existing aluminum alloy door and window blanking machine cuts aluminum profiles, in order to ensure the stability of cutting, it is necessary to tightly fix the cutting end of the aluminum profile. Most aluminum profiles are hollow, and the side walls of some aluminum profiles are relatively thin. A large pressing force will cause deformation at the end of the aluminum profile, while a small pressing force will cause shaking during cutting. It is impossible to avoid the deformation of the cutting end of the aluminum profile while tightly pressing the cutting end of the aluminum profile, which is inconvenient to use. Therefore, we propose a protection mechanism for an aluminum alloy door and window blanking machine to facilitate solving the problems raised above. Content of the Utility Model

[0029] Please refer to Figures 1 to 5 , a protection mechanism of an aluminum alloy door and window cutting machine, including a working box 1. A knife groove 2 is opened in the middle of the top of the working box 1. A cutting mechanism is installed inside the working box 1 corresponding to the knife groove 2. Among them,

[0030] An aluminum profile 9 is arranged on the top of the working box 1. A bracket 10 is fixedly connected to the top of the working box 1 near one side of the knife groove 2. A first pressing hydraulic rod 11 is installed on the inner top corresponding to the aluminum profile 9 of the bracket 10. A pressing plate 12 is installed at the telescopic end of the first pressing hydraulic rod 11. A fixed frame 13 is fixedly connected to the top of one end of the working box 1. A support rod 14 is fixedly connected to the fixed frame 13 corresponding to one side of the aluminum profile 9. A first toothed rod 15 is sleeved on the support rod 14 near one end of the aluminum profile 9. The first toothed rod 15 is sleeved on the support rod 14 through a support rod groove 16. A support rod 17 is installed at the end of the first toothed rod 15 near the aluminum profile 9;

[0031] A guide groove 18 is formed above the fixing bracket 13 close to the support rod 14. A second toothed rod 19 penetrates through the guide groove 18. A gear 20 is arranged between the first toothed rod 15 and the second toothed rod 19. The gear 20 is rotatably connected to the working box 1. A transmission rod 21 is rotatably connected between the pressing plate 12 and the end of the second toothed rod 19. A pushing hydraulic rod 22 is installed on the inner wall of the bracket 10 corresponding to the side of the aluminum profile 9. A pushing plate 23 is installed at the telescopic end of the pushing hydraulic rod 22. A limiting mechanism is arranged at one end of the working box 1 away from the fixing bracket 13.

[0032] The aluminum profile 9 is conveyed by a conveying device. After the cutting position of the aluminum profile 9 moves to the knife groove 2, the pressing hydraulic rod 11 drives the pressing plate 12 to move downward. At the same time, the pressing plate 12 pushes the second toothed rod 19 to move away from the knife groove 2 through the transmission rod 21. The second toothed rod 19 drives the first toothed rod 15 to move in the opposite direction through the gear 20, so that the first toothed rod 15 pushes the support rod 17 to insert into the cavity of the aluminum profile 9. When the pressing plate 12 presses the cutting end of the aluminum profile 9, the inner wall of the aluminum profile 9 is supported through the support rod 17, which can protect the aluminum profile 9 while pressing and fixing the aluminum profile 9, and prevent the aluminum profile 9 from being deformed by pressing. After cutting, the pressing plate 12 moves upward, thereby driving the support rod 17 to separate from the aluminum profile 9, so that the pushing hydraulic rod 22 pushes the cut aluminum profile 9 off the working box 1 through the pushing plate 23, and the conveying device continues to convey the aluminum profile 9 for the next cutting operation.

[0033] Please refer to Figures 1 to 5 As shown in the figure, the cutting mechanism includes a support frame 3. The support frame 3 is fixedly connected to the inner bottom of the working box 1. A frame 4 is vertically slidably connected to one side of the support frame 3 close to the knife groove 2. A first motor 7 is installed in the frame 4. A cutting blade 8 is installed at the shaft end of the first motor 7 corresponding to the knife groove 2. A lifting hydraulic rod 31 is installed on the inner bottom of the working box 1 corresponding to the frame 4. The telescopic end of the lifting hydraulic rod 31 is fixedly connected to the bottom of the frame 4. A first chute 5 is formed on one side of the support frame 3 close to the frame 4. A first slider 6 is fixedly connected to one side of the frame 4 corresponding to the first chute 5. After the aluminum profile 9 moves to the specified position, the lifting hydraulic rod 31 drives the frame 4 to move upward, thereby driving the first motor 7 and the cutting blade 8 to move upward. At the same time, the first motor 7 drives the cutting blade 8 to rotate, so that the cutting blade 8 extends out of the knife groove 2 to cut the aluminum profile 9. After cutting, the cutting blade 8 retracts into the working box 1, so that the aluminum profile 9 can continue to be loaded.

[0034] Please refer to Figures 1 to 5, the support rod 14 is rectangular columnar, and the external dimensions of the support rod 14 match the internal dimensions of the support rod groove 16. The limiting mechanism includes a support 24. A support 24 is fixedly installed at one end of the working box 1 away from the fixed frame 13. Second sliding grooves 25 are symmetrically formed at the top of the support 24. Second sliding blocks 26 are arranged in the second sliding grooves 25. A lead screw 27 penetrates through the second sliding grooves 25. One end of the support 24 is provided with a second motor 28. The shaft end of the second motor 28 is fixedly connected to the lead screw 27. The top of the second sliding block 26 is fixedly connected to a sliding seat 29. A limiting wheel 30 is rotatably connected to the top of the sliding seat 29. Two sections of opposite external threads are provided on the lead screw 27, and the lead screw 27 is threadedly connected to the second sliding block 26. By driving the lead screw 27 to rotate through the second motor 28, the two sections of opposite external threads on the lead screw 27 can drive the second sliding blocks 26 on both sides to approach or move away from each other. Furthermore, the second sliding block 26 can drive the limiting wheel 30 to move through the sliding seat 29, so that the limiting wheels 30 on both sides approach or move away from each other, and the limiting wheels 30 abut against both sides of the aluminum profile 9, which can limit the feeding of the aluminum profile 9 and prevent the aluminum profile 9 from shifting during feeding. At the same time, the distance between the limiting wheels 30 can be adjusted according to the size of the aluminum profile 9, so as to limit aluminum profiles 9 of different sizes.

[0035] Working principle: When using the protection mechanism of this aluminum alloy door and window cutting machine, such as Figures 1 to 5As shown in the figure, first, the aluminum profile 9 is conveyed by a conveying device. After the cutting position of the aluminum profile 9 moves to the position of the tool groove 2, the pressing hydraulic rod 11 drives the pressing plate 12 to move downward. At the same time, the pressing plate 12 pushes the second rack 19 to move away from the tool groove 2 through the transmission rod 21. The second rack 19 drives the first rack 15 to move in the opposite direction through the gear 20, so that the first rack 15 pushes the support rod 17 to insert into the cavity of the aluminum profile 9. When the pressing plate 12 presses the cutting end of the aluminum profile 9, the inner wall of the aluminum profile 9 is supported through the support rod 17, which can protect the aluminum profile 9 while pressing and fixing the aluminum profile 9, and prevent the aluminum profile 9 from being deformed by pressing. The end of the first rack 15 is fixedly connected to the support rod 17 by a bolt fixing method, and the support rod 17 can be replaced according to the cavity size and shape of the aluminum profile 9. At the same time, the lifting hydraulic rod 31 drives the frame 4 to move upward, thereby driving the first motor 7 and the cutting blade 8 to move upward. At the same time, the first motor 7 drives the cutting blade 8 to rotate, so that the cutting blade 8 extends out of the tool groove 2 and cuts the aluminum profile 9. After cutting, the cutting blade 8 retracts into the working box 1, so that the aluminum profile 9 can continue to be loaded. At the same time, the pressing plate 12 moves upward, thereby driving the support rod 17 to separate from the aluminum profile 9. The pushing hydraulic rod 22 pushes the cut aluminum profile 9 off the working box 1 through the pushing plate 23, and the conveying device continues to convey the aluminum profile 9 to perform the next cutting operation. The second motor 28 can drive the lead screw 27 to rotate. The lead screw 27 can drive the two second sliders 26 on both sides to approach or move away from each other through two opposite external threads. Then, the second slider 26 drives the limit wheel 30 to move through the sliding seat 29, so that the two limit wheels 30 on both sides approach or move away from each other, and the limit wheels 30 abut against both sides of the aluminum profile 9, which can limit the feeding of the aluminum profile 9 and prevent the aluminum profile 9 from shifting during feeding. At the same time, the distance between the limit wheels 30 can be adjusted according to the size of the aluminum profile 9, so as to limit aluminum profiles 9 of different sizes.
