[0002] An automatic metal sheet bending and cutting machine is a CNC device that integrates automatic bending and precise cutting functions. Through program control, it completes the fixed-length cutting and multi-angle bending of metal sheets (such as steel and aluminum sheets). Its core purpose is to replace manual step-by-step processing, improving the efficiency and precision of metal component production. Existing automatic metal sheet bending and cutting machines require operators to place metal sheets one by one into the machine, processing the first sheet before placing the next, and repeating this process. This results in poor continuity of bending and affects processing efficiency. Therefore, an automatic metal sheet bending and cutting machine is needed. Utility Model Content

The feeding assembly 5 includes a feeding rack 501, with an observation slot 502 at the end of the feeding rack 501. The pushing assembly 4 includes a slide 401, with the feeding rack 501 fixed to the top of the slide 401. A material placement slot 503 is provided on the top of the feeding rack 501, and a limiting plate 505 is fixedly connected to the inner side wall of the material placement slot 503. The limiting plate 505 can be used to place excess metal plates 403 so that they can be added directly into the discharge slot 504 when needed. A discharge slot 504 is provided at the bottom of the material placement slot 503. The slide groove 402 inside the slide 401 is slidably connected to the metal plate 403, and the discharge slot 504 corresponds to the metal plate 403. A second electric telescopic rod 7 is fixedly connected to the top of the slide 401, and a push plate 8 is fixedly connected to the output end of the second electric telescopic rod 7, with the push plate 8 corresponding to the position of the observation slot 502. When the device is in use, the metal plate 403 is placed in the material trough 503. As the operator pushes it, it moves towards the discharge trough 504, thus entering the slide 402 from the discharge trough 504. A portion of the metal plate 403 will also accumulate inside the discharge trough 504. Then, the pushing component 4 is activated to gradually push the metal plate 403 inside the slide 402 towards the bending component 2. After bending, the cutting component 3 cuts the metal plate 403 until one metal plate 403 is used up. The pushing component 4 returns to its initial position, and the metal plate 403 above will continue to enter the slide 402 along the discharge trough 504 to repeat the operation with the pushing component 4. This helps to enhance the continuity of the device's use. When the metal plate 403 inside the material trough 503 is used up and needs to be added, the device can continue to operate without being shut down, which helps to improve the processing efficiency of the metal plate 403.
[0016] The top of the slide block 401 is fixedly connected to a limit bracket 6. There are two limit brackets 6, which are respectively attached to both ends of the push plate 8. The limit brackets 6 on both sides protect the push plate 8 and prevent it from being damaged.
[0017] The bending assembly 2 includes a fixed frame 201, a motor 202 fixedly connected to the inner bottom of the fixed frame 201, a rotating column 203 fixedly connected to the output end of the motor 202, a turntable 204 fixedly connected to the top of the rotating column 203. When the motor 202 starts, it drives the turntable 204 to rotate through the rotating column 203.
[0018] The top of the operating table 1 has a circular groove, and the turntable 204 is located inside the circular groove. A bending limiting post 205 is fixedly connected to the top of the turntable 204. There are two bending limiting posts 205, and they correspond to the positions of the metal plate 403. When the turntable 204 rotates, it rotates and bends the metal plate 403 that is pushed between the two bending limiting posts 205.
[0019] The cutting assembly 3 includes a hydraulic telescopic rod 301. A connector 302 is fixedly connected to the output end of the hydraulic telescopic rod 301. A cutter 303 is fixedly connected to the end of the connector 302. An operating groove 406 and a connecting groove 407 are formed on the inner wall of the slide groove 402. The cutter 303 is located inside the operating groove 406. The hydraulic telescopic rod 301 is connected to a hydraulic cylinder via a pipeline. The hydraulic cylinder drives the hydraulic telescopic rod 301 to extend, and the connector 302 drives the cutter 303 to cut the metal plate 403, so that the end of the cutter 303 is located inside the connecting groove 407.
[0020] A slider 404 is slidably connected inside the slide groove 402. A first electric telescopic rod 405 is fixedly connected to the end of the slider 404, and the first electric telescopic rod 405 is located on the top of the operating table 1. The slider 404 is driven by the first electric telescopic rod 405 to facilitate the pushing of the metal plate 403.
[0021] Working principle: When the device is in use, the metal plate 403 is placed in the material trough 503. As the operator pushes it, it moves towards the discharge trough 504, thus entering the slide 402 from the discharge trough 504. A portion of the metal plate 403 will also accumulate inside the discharge trough 504. Then, the pushing component 4 is activated to gradually push the metal plate 403 located inside the slide 402 towards the bending component 2. After bending, the cutting component 3 cuts the metal plate 403 until one metal plate 403 is used up. The pushing component 4 returns to its initial position, and the metal plate 403 above will continue to enter the slide 402 along the discharge trough 504 to cooperate with the pushing component 4 for repeated operation, which helps to enhance the continuity of the device's use. When the metal plate 403 inside the material trough 503 is used up and needs to be added, the device can continue to operate without shutting down, which helps to improve the processing efficiency of the metal plate 403.
