The monitoring equipment can capture images and videos of the punching and shearing process in real time, providing operators with an intuitive monitoring screen, which helps operators to detect abnormalities in time, such as punching and shearing position deviation, material jamming, etc., and take corresponding countermeasures.

[0024] 2. Through the design of the feeding mechanism, during the punching and shearing process, the placement plate is held on the punching and shearing table to hold the sheet metal material for punching and shearing. When the punching and shearing is completed, the motor drives the placement plate to move into the mounting plate, thereby pushing the sheet metal material onto the conveyor belt. This allows the material to be automatically transported to the designated position immediately after punching and shearing, reducing manual intervention, thus speeding up production, shortening the production cycle, reducing reliance on operators, lowering labor costs, improving production efficiency and product quality, and reducing the opportunity for operators to come into contact with the punching and shearing device, thereby reducing the risk of safety accidents.

[0033] The punching and shearing protection mechanism is installed on the top plate 3 and is used to enclose sheet metal materials for punching and shearing.

[0034] The protective box 706 is slidably mounted on the punching and shearing protection mechanism. A monitoring device is installed inside the protective box 706. The protective box 706 seals the punching and shearing area during punching and shearing operations, and the monitoring device monitors the punching and shearing process in real time.

[0035] The unloading mechanism is located at the bottom of the punching and shearing table 1 and is used to intermittently unload the punched and sheared sheet metal from the punching and shearing table 1.

[0036] The shelf 907 is slidably mounted on the unloading mechanism. The front section of the shelf 907 is provided with an inclined groove, and the two sides of the shelf 907 are symmetrically provided with connecting grooves for placing sheet metal to be processed. The shelf 907 can also close and open the opening of the punching and shearing table 1 by sliding.

[0037] The clamping assembly includes a rotating rod 801, a threaded rod 802, and a clamping plate 803. The threaded rod 802 is rotatably mounted on the side of the punching and shearing table 1, and the threaded rod 802 and the punching and shearing table 1 are threadedly connected. There are two threaded rods 802 symmetrically arranged about the punching and shearing table 1. The rotating rod 801 is located at the end of the threaded rod 802, and the clamping plate 803 is located at the end of the threaded rod 802 away from the rotating rod 801. Rotating the rotating rod 801 causes the threaded rod 802 to rotate, thereby moving the threaded rod 802 on the punching and shearing table 1. At the same time, the movement of the two threaded rods 802 is controlled to limit the sheet metal material on the placement plate 907 to facilitate the punching and shearing operation.

[0038] The punching and shearing protection mechanism includes a hydraulic cylinder 701, a punching rod 702, a fixed plate 703, a spring 705, and a telescopic rod 704. The hydraulic cylinder 701 is located at the top of the top plate 3, the punching rod 702 is located at the output end of the hydraulic cylinder 701, the fixed plate 703 is located on the outside of the punching plate, the telescopic rod 704 is located at the bottom of the fixed plate 703, the spring 705 is located on the outside of the telescopic rod 704, the end of the telescopic rod 704 away from the fixed plate 703 is connected to the top of the protective box 706, and the inner side of the protective box 706 is slidably connected to the outer side of the punching rod 702.

Before punching and shearing, the two sliding doors 708 are connected together by the locking block and the slot. Then, the hydraulic cylinder 701 is activated, which drives the punching rod 702 to press down. The punching rod 702 drives the fixed plate 703 and the punching and shearing die 709 to press down. The bottom of the protective box 706 is located below the punching and shearing die 709. Therefore, the protective box 706 first contacts the punching and shearing table 1. Then, the punching rod 702 drives the punching and shearing die 709 to continue to press down. At this time, the protective box 706 slides on the punching rod 702 and the spring 705 and the telescopic rod 704 are compressed. Then, the sheet metal material inside is punched and sheared. The protective box 706 blocks the scrap material ejected by punching and shearing. After punching and shearing is completed, the hydraulic cylinder 701 drives the protective box 706 and the punching and shearing die 709 to return to their original positions. The two sliding doors 708 can be opened to replace the punching and shearing die 709.

[0039] Example 2

[0040] like Figures 4-5 As shown, this utility model proposes a material punching and shearing device. Compared with Embodiment 1, this embodiment details the structure of the feeding mechanism.

[0041] The unloading mechanism includes a power component and an unloading component. The power component is located at the bottom of the punching and shearing table 1 and provides power to the unloading component. The unloading component is located at the bottom of the punching and shearing table 1 and is situated to the side of the power component. It is used to automatically unload the punched and sheared sheet metal material. The power component includes a fixed frame 902, a motor 901, a rotating shaft 903, and a lever 904. The fixed frame 902 is located at the bottom of the punching and shearing table 1. The motor 901 is located inside the fixed frame 902. The rotating shaft 903 is located at the output end of the motor 901. The lever 904 is located at the end of the rotating shaft 903 away from the motor 901. When the motor 901 is started, the motor 901 drives the rotating shaft 903 to rotate, and the rotating shaft 903 drives the lever 904 to rotate. The unloading assembly includes a guide table 906, a connecting frame 912, a fixing rod 905, and a slide bar 910. The fixing rod 905 is located at the bottom of the shelf 907. The slide bar 910 is slidably mounted on both sides of the shelf 907. A mounting plate 908 is located on the side of the slide bar 910 away from the shelf 907. A telescopic rod 911 is located on the inner side of the mounting plate 908. Two telescopic rods 911 are symmetrically arranged about the mounting plate 908. A spring 909 is located on the outer side of the telescopic rod 911. The end of the telescopic rod 911 away from the mounting plate 908 is connected to the end face of the shelf 907. The connecting frame 912 is symmetrically arranged on both sides of the punching and shearing table 1. The guide table 906 is located at the end of the connecting frame 912 away from the punching and shearing table 1. The inclination of the guide table 906 is the same as the inclination of the inclined groove on the shelf 907. Each time the lever 904 rotates to the fixed rod 905, it drives the fixed plate 703 to move. The fixed rod 905 drives the shelf 907 to move towards the mounting plate 908. During the movement, the telescopic rod 911 and the spring 909 are compressed. Since the sheet metal material is placed on the shelf 907, the shelf 907 can be pushed down by the punching and shearing table 1 when it moves, and slide onto the conveyor belt 6 through the inclined groove of the shelf 907 and the guide table 906, and be transported to the next process by the conveyor belt 6.

[0042] In summary, when using this utility model, the sheet metal material is placed on the shelf 907, and then the rotating rod 801 is rotated. The rotating rod 801 drives the threaded rod 802 to rotate, thereby causing the threaded rod 802 to move on the punching and shearing table 1. At the same time, the movement of the two threaded rods 802 is controlled to restrict the sheet metal material to the center of the shelf 907. Then, the two sliding doors 708 are connected together by the cooperation of the locking block and the locking groove. Then, the hydraulic cylinder 701 is activated, and the hydraulic cylinder 701 drives the punching rod 702 to press down. The punching rod 702 drives the fixing plate 703 and the punching and shearing die 709 to press down. The protective box 706 first contacts the punching and shearing table 1 to seal the punching and shearing area. Then, the punching rod 702 drives the punching and shearing die 709 to continue to press down. At this time, the protective box 706 slides on the punching rod 702 and the spring 705 and the telescopic rod 704 are compressed. Then, the internal sheet metal is pressed down. The sheet metal material is punched and sheared. The protective box 706 blocks the scrap ejected from the punching and shearing. At the same time, the motor 901 is started, which drives the rotating shaft 903 to rotate. The rotating shaft 903 drives the lever 904 to rotate. Each time the lever 904 rotates to the fixed rod 905, it drives the fixed plate 703 to move. The fixed rod 905 drives the placement plate 907 to move towards the mounting plate 908. Since the sheet metal material is placed on the placement plate 907, it can be pushed down by the punching and shearing table 1 when the placement plate 907 moves. It can then slide onto the conveyor belt 6 through the inclined groove of the placement plate 907 and the guide table 906, and then be transported to the next process by the conveyor belt 6. After the punching and shearing is completed, the hydraulic cylinder 701 drives the protective box 706 and the punching and shearing die 709 to return to their original positions. The placement plate 907 returns to its original position under the action of the second spring 909 and the second telescopic rod 911.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
