[0002] Doors and windows, as a kind of enclosure or partition components, are an important part of the building envelope system. With the advancement of technology, the material of doors and windows has changed from wooden doors and windows to more durable metal doors and windows. Due to the different sizes of building maintenance structures, the sizes of doors and windows to be installed are also different. Therefore, most of the existing doors and windows need to be measured and customized on site, and during the processing process, cutting devices are needed to cut the metal raw materials for door and window processing.

[0003] In the patent (application number: CN202121876181.6), a metal door and window cutting device is disclosed, including a base plate, a support plate fixedly connected to the upper side of the base plate, the support plate rotatably connected to a round tube, two guide holes are symmetrically arranged on the round tube, a guide rod is slidably connected in each guide hole, one end of each guide rod is fixedly connected to a clamping plate, two threaded holes are arranged on the round tube, a threaded rod is threadedly connected in each threaded hole, and one end of each threaded rod extending into the round tube is rotatably connected to its corresponding clamping plate, a slide groove is arranged on the upper side of the base plate, a slider is slidably connected in the slide groove, the upper side of the slider is fixedly connected to the support plate, one side of the support plate is fixedly connected to the first cylinder, the end of the telescopic rod of the first cylinder is fixedly connected to the side plate, the side plate is slidably connected to the sliding block, one side of each sliding block is fixedly connected to an oblique rod, and the end of each oblique rod is fixedly connected to a scraper. The utility model embeds a part of the tip of the scraper into the corner of the square tube, and as the slider slides in the slide groove, the burrs on the corner of the square tube are scraped, thereby improving the burr removal efficiency.

[0004] This patent and the prior art have the following technical problems in actual use:

[0005] During the metal cutting process, the contact force between the cutting tool (such as a saw blade, etc.) and the metal surface changes dynamically. If the cutting force is unevenly distributed, it may cause vibration. For example, the sharpness of the cutting tool and the uniformity of the pressure will affect the stability of the cutting force. Vibration will cause the contact between the cutting tool and the metal surface to be unstable, which may cause cutting errors. Especially for cutting with high precision requirements, vibration will affect the accuracy of the size, resulting in the size of the processed metal doors and windows not meeting the requirements.

[0031] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] A metal cutting device for door and window manufacturing according to a preferred embodiment of the present invention will be described in detail below.

[0033] Embodiment 1, as Figure 1-Figure 7 As shown, it comprises a cutting table 1, a support frame 2 is fixedly installed on the top of the cutting table 1, and a fixing mechanism 3 and a cutting mechanism 4 are arranged inside the support frame 2;

[0034] The fixing mechanism 3 includes a fixing frame 301 arranged inside the support frame 2, and connecting members 302 are fixedly installed on both sides of the fixing frame 301, and the connecting members 302 are symmetrically arranged in two groups. A fixing clamp 303 is rotatably installed inside the connecting member 302, and a linkage frame 304 is arranged inside the fixing frame 301. The surface of the linkage frame 304 is provided with sliding grooves 305, and the sliding grooves 305 are symmetrically arranged in two groups. A sliding block 306 slidably connected to the sliding grooves 305 is fixedly installed on the surface of the fixing frame 301;

[0035] A first rack 307 is rotatably mounted on one side of the fixing clamp 303, a second rack 308 is fixedly mounted on the surface of the linkage frame 304, a connecting gear 309 is rotatably mounted between the inner walls of the fixing frame 301, the connecting gear 309 is located between the first rack 307 and the second rack 308, and is meshed and connected with the first rack 307 and the second rack 308, the number of the second rack 308 is set to be the same as the first rack 307, a linkage rod 310 is arranged inside the linkage frame 304, matching plates 311 are fixedly mounted on both sides of the linkage rod 310, a return spring 314 is fixedly mounted between the matching plates 311 and the inner wall of the linkage frame 304, a linkage latch 312 is fixedly mounted on the inner wall of the linkage frame 304, and a linkage groove 313 matching with the linkage latch 312 is fixedly mounted on the surface of the linkage rod 310;

[0036] The staff first places the door and window metal to be cut on the surface of the cutting table 1, and then controls the driving assembly to drive the linkage rod 310 to move downward. When the linkage rod 310 moves downward, the matching plates 311 on both sides of the linkage rod 310 drive the linkage frame 304 to move downward through the reset spring 314. When the linkage frame 304 moves downward, it can drive the fixed frame 301 to move downward synchronously. In this process, the fixed frame 301 first contacts the metal surface of the door and window. When the fixed frame 301 contacts the metal of the door and window, it cannot continue to move downward. When moving, the continuous movement of the linkage rod 310 will drive the linkage frame 304 to move downward through the reset spring 314. At this time, the sliding block 306 on the surface of the fixed frame 301 slides in the sliding groove 305 on the surface of the linkage frame 304. At this time, as the linkage frame 304 moves downward, it can drive the second rack 308 to continue to move downward, and at the same time mesh with the connecting gear 309, and drive the connecting gear 309 to rotate on the inner wall of the fixed frame 301. As the connecting gear 309 rotates, it will mesh with the first rack 307, thereby driving the first rack 307 When the first rack 307 moves upward, it will drive the fixing clamp 303 to move upward. However, since the surface of the fixing clamp 303 is rotatably connected with the connecting piece 302, the fixing clamp 303 will rotate relatively and make a clamping motion trajectory, thereby clamping and fixing the metal of the door and window. When the linkage rod 310 continues to move downward, the linkage pin 312 on the inner wall of the linkage frame 304 will slide in the linkage groove 313 on the surface of the linkage rod 310 and engage with the linkage groove 313. Then, the metal of the door and window can be cut by the cutting mechanism 4. During the cutting process, since the metal of the door and window will vibrate when being cut, when the vibration amplitude of the metal of the door and window is too large, the fixing clamp 303 will follow the vibration of the metal of the door and window, so that the linkage latch 312 on the inner wall of the linkage frame 304 will vibrate synchronously. When the vibration amplitude is large, the linkage latch 312 will slide and separate from the groove inside the linkage groove 313. At this time, the reset spring 314 will push the linkage frame 304 to reset. When the linkage frame 304 resets, the above steps will be reversed, so that the fixing clamp 303 will release the clamping of the metal of the door and window.

[0037] When large vibration occurs during the cutting process of door and window metal, loosening the clamping of the fixing mechanism 3 can effectively avoid uneven force on the door and window metal due to excessive vibration, thereby avoiding deformation or damage. This helps to ensure the integrity and cutting quality of the workpiece. At the same time, when the fixing mechanism 3 is loosened, the stress concentration caused by excessive clamping can be reduced, ensuring that the door and window metal can be cut more smoothly during the cutting process.

[0038] Embodiment 2, as Figure 1-Figure 6As shown, a vibration sensor 5 is fixedly installed on one side of the linkage rod 310, a first electric telescopic rod 6 is fixedly installed on the top of the linkage rod 310, two groups of fixing mechanisms 3 are symmetrically arranged, a positive and negative threaded rod 7 is rotatably installed between the inner walls of the support frame 2, an adjustment motor 8 is fixedly installed on one side of the support frame 2, an output end of the adjustment motor 8 is fixedly connected to one end of the positive and negative threaded rod 7, a connecting screw sleeve 9 is threadedly connected to the surface of the positive and negative threaded rod 7, and two groups of connecting screw sleeves 9 are symmetrically arranged, and both connecting screw sleeves 9 are fixedly connected to the first electric telescopic rod 6;

[0039] The staff can control the adjustment motor 8 to drive the positive and negative threaded rod 7 to rotate. During the rotation of the positive and negative threaded rod 7, it meshes with the connecting screw sleeve 9 and makes it move relatively, which can drive the two sets of fixing mechanisms 3 to move relative to or away from each other;

[0040] By adjusting the positions of the two sets of fixing mechanisms 3, the stability of the metal workpiece during the cutting process can be ensured, so that the metal workpiece will not be displaced or deformed during the cutting process. Accurate fixing helps to ensure the alignment of the workpiece during cutting, thereby improving the cutting accuracy and reducing errors.

[0041] Embodiment three, as Figure 1-Figure 7 As shown, the cutting mechanism 4 includes a cutting knife 401 arranged below the forward and reverse threaded rod 7, a support box 402 is arranged above the cutting knife 401, a first gear 403 is rotatably mounted on the inner bottom of the support box 402, a mounting frame 404 is arranged above the cutting knife 401, the mounting frame 404 is rotatably connected to the cutting knife 401, the mounting frame 404 is fixedly connected to the first gear 403, a cutting motor 405 is fixedly installed on one side of the mounting frame 404, and the output end of the cutting motor 405 is fixedly connected to the cutting knife 401;

[0042] When the cutting angle of the cutting knife 401 needs to be adjusted, it is only necessary to control the rotation of the first gear 403 to drive the cutting knife 401 to rotate synchronously through the mounting frame 404, and the provided cutting motor 405 can drive the cutting knife 401 to rotate, thereby driving the cutting knife 401 to cut the metal of doors and windows.

[0043] Embodiment 4, as Figure 1-Figure 7 As shown, the inner bottom of the support box 402 is rotatably mounted with a second gear 406, the second gear 406 is meshedly connected with the first gear 403, the top of the support box 402 is fixedly mounted with a servo motor 407, the output end of the servo motor 407 is fixedly connected with the second gear 406, the top of the support box 402 is fixedly mounted with a connecting frame 10, a second electric telescopic rod 11 is arranged above the connecting frame 10, the output end of the second electric telescopic rod 11 is fixedly connected with the top of the connecting frame 10, and the second electric telescopic rod 11 is rotatably connected with the forward and reverse threaded rod 7;

[0044] When the servo motor 407 is started, the output end of the servo motor 407 can drive the second gear 406 to rotate. The second gear 406 engages with the first gear 403 when rotating. When the first gear 403 rotates, it can drive the mounting bracket 404 to rotate, thereby adjusting the cutting angle of the cutting knife 401, so as to facilitate the staff to adjust the cutting position, which is suitable for different cutting requirements.

[0045] Embodiment 5, as Figure 1-Figure 7 As shown, a rotating roller is rotatably installed between the inner walls of the cutting table 1, and a plurality of rotating rollers are provided.
