[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a corner folding device for hardware processing, including a base 1, a pressure plate 2 is fixedly installed on one side of the surface of the base 1, a pushing mechanism 3 is arranged on one side of the surface of the base 1, and a stamping mechanism 4 is arranged on one side of the surface of the pressure plate 2;

[0021] The stamping mechanism 4 includes a module 401, a limit plate 402, a cylinder 403, a first baffle 404, a forming block 405, a first fixing bolt 406, a movable plate 407, a second fixing bolt 408, a spring 409, a second baffle 410 and a stamping block 411. On one side of the surface of the pressing plate 2, the module 401 is fixedly installed. On one side of the surface of the module 401, the limit plate 402 is bolted. Inside the module 401, the cylinder 403 is installed. On one side of the surface of the module 401, the first baffle 404 is bolted. Inside the module 401, the forming block 405 is fitted. On one side of the surface of the module 401, the first fixing bolt 406 is fixedly connected. At one end of the cylinder 403, the movable plate 407 is fixedly installed. On one side of the surface of the forming block 405, the second fixing bolt 408 is fixedly connected. On one side of the surface of the first fixing bolt 406, the spring 409 is fixedly connected. On one side of the surface of the movable plate 407, the second baffle 410 is bolted. Inside the movable plate 407, the stamping block 411 is fixedly installed. Through the settings of the module 401, the limit plate 402, the cylinder 403, the first baffle 404, the forming block 405, the first fixing bolt 406, the movable plate 407, the second fixing bolt 408, the spring 409, the second baffle 410 and the stamping block 411, when making a fold angle, first place the workpiece on one side of the surface of the module 401. The limit plate 402 limits the workpiece to prevent the workpiece from moving left and right. Then start the cylinder 403. One end of the cylinder 403 penetrates through the limit plate 402, and its telescopic movement pushes the connected movable plate 407. The movable plate 407 makes a linear movement under the action of the cylinder 403. The stamping block 411 inside the movable plate 407 moves along with the movement of the movable plate 407. When the movable plate 407 moves towards the forming block 405, the stamping block 411 stamps the workpiece placed on the forming block 405. In this process, the first baffle 404 plays a role of blocking and positioning to ensure the stable position of the forming block 405 during work. The first fixing bolt 406 and the second fixing bolt 408 are used to fix both ends of the spring 409. When the movable plate 407 drives the stamping block 411 to perform a stamping action, the spring 409 is stretched or compressed, playing a role of buffering and resetting. When the cylinder 403 retracts, the elastic force of the spring 409 helps the movable plate 407 and the stamping block 411 return to the initial position to prepare for the next stamping. Through the setting of the second baffle 410, it ensures the accurate installation position of the stamping block 411 inside the movable plate 407, prevents the stamping block 411 from shifting or misaligning during work, and guarantees the accuracy and stability of the stamping action.

[0022] Furthermore, one end of the cylinder 403 penetrates through the limit plate 402, and the first baffle 404 is installed on one side of the surface of the forming block 405. Through the setting of the first baffle 404, it plays a positioning role for the forming block 405 to ensure the accurate installation position of the forming block 405 inside the module 401, so that it remains stable during stamping and does not displace.

[0023] Further, one end of the spring 409 is fixedly connected to one side of the surface of the second fixing bolt 408, and the second baffle 410 is bolted to one side of the surface of the stamping block 411. Through the arrangement of the spring 409, when the air cylinder 403 retracts, the elastic restoring force of the spring 409 pushes the movable plate 407 and the stamping block 411 back to the initial position, preparing for the next stamping.

[0024] Further, there are two sets of stamping blocks 411 and two sets of springs 409. Through the arrangement of the stamping blocks 411, the stamping blocks 411 are in direct contact with the workpiece, applying pressure to cause the workpiece to deform according to the design requirements, achieving the purpose of stamping forming.

[0025] Further, the pushing mechanism 3 includes a motor 301, a movable shaft 302, a disc 303, a limiting block 304, a mounting block 305, a connecting rod 306, a fixing block 307, and a pushing block 308. A motor 301 is fixedly installed on one side of the surface of the base 1. A movable shaft 302 is fixedly installed on one side of the surface of the motor 301. One end of the movable shaft 302 is fixedly installed with a disc 303. A limiting block 304 is installed on one side of the surface of the disc 303. A mounting block 305 is fixedly installed on one side of the surface of the disc 303. A connecting rod 306 is fixedly connected to one side of the surface of the limiting block 304. A fixing block 307 is installed on one side of the surface of the connecting rod 306. One end of the connecting rod 306 is fixedly connected to a pushing block 308. Through the arrangement of the motor 301, the movable shaft 302, the disc 303, the limiting block 304, the mounting block 305, the connecting rod 306, the fixing block 307, and the pushing block 308, after the motor 301 is started, it drives the movable shaft 302 to rotate. The disc 303 at one end of the movable shaft 302 rotates accordingly. The mounting block 305 on one side of the surface of the disc 303 makes a circular motion as the disc 303 rotates. The mounting block 305 installed on the inner surface of the limiting block 304 is connected to the pushing block 308 through the connecting rod 306. When the disc 303 rotates, the circular motion of the mounting block 305 is converted into a linear reciprocating motion of the pushing block 308 through the connecting rod 306. The fixing block 307 is used to fix and limit the movement range of the connecting rod 306, ensuring the smooth and accurate movement of the pushing block 308. The pushing block 308 is pushed by the connecting rod 306 to push the workpiece, thereby removing the stamped workpiece from the surface of the stamping block 411.

[0026] Further, the mounting block 305 is installed on one side of the inner surface of the limiting block 304, and the connecting rod 306 is installed on one side of the surface of the disc 303. Through the arrangement of the connecting rod 306, the connecting rod 306 conducts the power generated by the rotation of the disc 303 to the pushing block 308, enabling the pushing block 308 to obtain a thrust to push the workpiece.

[0027] Furthermore, the fixing block 307 is fixedly installed on one side of the surface of the pressing plate 2. Through the setting of the fixing block 307, the fixing block 307 is used to fix and limit the movement range of the connecting rod 306, ensuring the smooth and accurate movement of the pushing block 308.

[0028] Working principle: When performing a corner fold, first place the workpiece on one side of the surface of the module 401. The limiting plate 402 limits the workpiece to prevent it from moving left and right. Then, start the cylinder 403. One end of the cylinder 403 penetrates through the limiting plate 402, and its telescopic movement pushes the connected movable plate 407. The movable plate 407 performs a linear movement under the action of the cylinder 403. The stamping block 411 inside the movable plate 407 moves along with the movement of the movable plate 407. When the movable plate 407 moves towards the forming block 405, the stamping block 411 performs stamping processing on the workpiece placed on the forming block 405. During this process, the first baffle 404 plays a role in blocking and positioning, ensuring the stable position of the forming block 405 during operation. The first fixing bolt 406 and the second fixing bolt 408 are used to fix both ends of the spring 409. When the movable plate 407 drives the stamping block 411 to perform a stamping action, the spring 409 is stretched or compressed, playing a role in buffering and resetting. When the cylinder 403 retracts, the elastic force of the spring 409 helps the movable plate 407 and the stamping block 411 return to the initial position, preparing for the next stamping. Through the setting of the second baffle 410, it ensures the accurate installation position of the stamping block 411 inside the movable plate 407, preventing the stamping block 411 from shifting or misaligning during the working process, and ensuring the accuracy and stability of the stamping action. After the motor 301 is started, it drives the movable shaft 302 to rotate. The disc 303 at one end of the movable shaft 302 rotates accordingly. The mounting block 305 on one side of the surface of the disc 303 performs a circular motion along with the rotation of the disc 303. The mounting block 305 installed on the inner surface of the limiting block 304 is connected to the pushing block 308 through the connecting rod 306. When the disc 303 rotates, the circular motion of the mounting block 305 is converted into a linear reciprocating motion of the pushing block 308 through the connecting rod 306. The fixing block 307 is used to fix and limit the movement range of the connecting rod 306, ensuring the smooth and accurate movement of the pushing block 308. The pushing block 308 is pushed by the connecting rod 306 to push the workpiece, thereby removing the stamped workpiece from the surface of the stamping block 411.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
