[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a hood hinge bracket stamping die, including a stamping box 1. A moving mechanism 3 is fixedly connected to the outer surface of the stamping box 1. A stamping mechanism 4 is arranged on the top of the stamping box 1. The moving mechanism 3 includes a U-shaped frame 301, a controller 310 and a position sensor 311. A driving motor 302 is arranged on the outer surface of the U-shaped frame 301. The output end of the driving motor 302 slidably penetrates the outer surface of the U-shaped frame 301 and extends to one side. The output end of the driving motor 302 is fixedly connected to a threaded lead screw 303. A moving plate 304 is threadedly connected to the outer surface of the threaded lead screw 303. Two limit columns 305 are slidably connected to the inner walls on both sides of the moving plate 304. The outer surface of the moving plate 304 is in contact with the inner wall of the stamping box 1. A plurality of fixed columns 306 are fixedly connected to the top of the moving plate 304 near the center. A plurality of fixed columns 306 are fixedly connected to the top of the operating plate 307. A notch 308 is opened at the top of the operating plate 307 near the center. The outer surface of the U-shaped frame 301 is fixedly connected to the outer surface of the stamping box 1. A metal sheet 309 is movably installed on the top of the operating plate 307. The outer surface of the controller 310 is fixedly installed on the outer surface of the stamping box 1. The outer surface of the position sensor 311 is fixedly installed on the inner wall of the stamping box 1.

[0023] The effect achieved by the entire Embodiment 1 is that when using the stamping die for the hood hinge bracket, first, the metal sheet 309 to be processed is placed on the operation plate 307, and a notch 308 is stamped on the operation plate 307. Subsequently, the drive motor 302 is started through the controller 310, and its output end drives the threaded lead screw 303 to rotate. While the threaded lead screw 303 rotates, it drives the moving plate 304 to perform translational movement. And under the action of the limit post 305, the stability of the moving plate 304 during movement is ensured, preventing deviation. When the moving plate 304 completely enters the stamping box 1, then, the position sensor 311 will monitor the position of the moving plate 304 in real time. When the moving plate 304 reaches the stamping position, the position sensor 311 will send a signal. After receiving this signal, the controller 310 will stop the operation of the drive motor 302. At this time, the moving plate 304 stops moving, preparing for the next stamping operation. After the stamping operation is completed, the drive motor 302 is started again, and the drive motor 302 will drive the moving plate 304 to return along the original path until it completely moves out of the position of the U-shaped frame 301. Finally, the operator can conveniently take out the stamped metal sheet 309 for the next round of operation or subsequent processing. Under the action of the moving mechanism 3, the operator can easily take out the stamped metal sheet 309 from the die, effectively solving the problem that it is not easy to take out after the traditional stamping process, not only improving the convenience of operation but also improving work efficiency. The fixed column 306 is mainly used for connection and fixation.

[0024] Embodiment 2, as Figures 1 - 4 shown, the stamping mechanism 4 includes a hydraulic cylinder 401. The hydraulic cylinder 401 is arranged on the top of the stamping box 1. The telescopic end of the hydraulic cylinder 401 slides through the top of the stamping box 1 and extends downward. The telescopic end of the hydraulic cylinder 401 is fixedly connected with a connecting plate 402. Two dampers 403 are arranged near the edge of the bottom of the connecting plate 402. Two springs 404 are arranged on the outer surfaces of the two dampers 403. The bottoms of the two dampers 403 are fixedly connected with two connecting columns 405. A fixed block 406 is fixedly connected at the position near the center of the bottom of the connecting plate 402. A plurality of support columns 2 are fixedly connected at the positions near the four corners of the bottom of the stamping box 1.

[0025] The effect achieved by the entire Embodiment 2 is that when using a stamping die, when the metal sheet 309 reaches the preset stamping position, at this time, by starting the hydraulic cylinder 401, its telescopic end drives the connecting plate 402 to move up and down. During the downward pressing process of the connecting plate 402, since the length of the connecting column 405 exceeds the fixed block 406, the connecting column 405 will first come into contact with the metal sheet 309. At this time, under the action of the damper 403 and the spring 404, they can absorb and buffer the impact force during the downward pressing process, causing the spring 404 to be compressed, thereby ensuring that the connecting plate 402 can continue to press down smoothly. When the connecting column 405 is in close contact with the metal sheet 309, it not only plays a role in fixing the sheet, but also effectively prevents the situation of popping out under pressure during the stamping process. Finally, the fixed block 406 will follow the downward pressing to complete the stamping work on the metal sheet 309. Under the action of the stamping mechanism 4, it can effectively buffer the impact force during the stamping process, thereby ensuring the smooth progress of the stamping process, and also plays a fixing role, avoiding the situation of displacement or popping out under the pressure during the stamping process. It not only improves the stability of stamping, but also improves the safety of operation. The support column 2 is mainly used for fixed connection.

[0026] Working principle: Place the metal sheet 309 on the operation board 307 and perform stamping on the reserved notch 308 on the operation board 307. Subsequently, start the driving motor 302 through the controller 310 to drive the threaded lead screw 303 to rotate. While the threaded lead screw 303 is rotating, it will drive the moving plate 304 to move horizontally. And under the action of the limit column 305, the stability of the moving plate 304 during movement is ensured. When the moving plate 304 completely enters the stamping box 1, then, the position sensor 311 will monitor the position of the moving plate 304 in real time. When the moving plate 304 reaches the stamping position, the position sensor 311 will send a signal. After the controller 310 receives this signal, it will stop the operation of the driving motor 302. At this time, the moving plate 304 stops moving. When the stamping work is completed, start the driving motor 302 again. The driving motor 302 will drive the moving plate 304 to return along the original path until it completely moves out of the position of the U-shaped frame 301. Finally, the operator can conveniently take out the stamped metal sheet 309. At this time, by starting the hydraulic cylinder 401, the connecting plate 402 is driven to move up and down. During the downward pressing process of the connecting plate 402, since the length of the connecting column 405 exceeds the fixed block 406, the connecting column 405 will first come into contact with the metal sheet 309. At this time, under the action of the damper 403 and the spring 404, they can absorb and buffer the impact force during the downward pressing process, causing the spring 404 to be compressed. When the connecting column 405 is in close contact with the metal sheet 309, finally, the fixed block 406 will follow the downward pressing to complete the stamping work on the metal sheet 309.

Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
