[0043] In the present embodiment: when the feeding mechanism for metal stamping is used, multiple groups of metal plates (not shown in the figure) are first stacked and placed inside the material box 301. When feeding and stamping are required, the threaded cylinder 311 is first rotated. Since the threaded cylinder 311 and the threaded rod 312 are threadedly connected, the threaded rod 312 is driven to move inside the threaded cylinder 311, and then the adjustment plate 313 is driven to move. The adjustment plate 313 drives the round rod (not shown in the figure) to slide in the limiting slot. The adjusting plate 313 can be limited by the round rod, so that the adjusting plate 313 is more stable during the movement process. Then the adjustment plate 313 moves and drives the reset plate 1 314 to move, so that the position height of the reset plate 1 314 can be adjusted, so that the position of the reset plate 1 314 can be appropriately adjusted according to the thickness of the metal plate, so that the contact area between the reset plate 1 314 and the metal plate is larger, providing a better pushing effect;

[0044] By rotating the adjusting screw 317, the baffle plate 318 is driven to move, so that the position of the baffle plate 318 can be adjusted, so that it can be suitable for the discharge operation of metal plates of different thicknesses to avoid the discharge of multiple groups of metal plates together, thereby further improving the use effect of the device and meeting the actual use needs. Subsequently, the driving motor 321 is started to drive the reciprocating screw rod 302 to rotate. Since the reciprocating screw rod 302 and the push plate 304 are threadedly connected, the push plate 304 is driven to move. Through the movement of the push plate 304, the reset plate 314 is driven to move synchronously. When the reset plate 314 contacts the metal plates at the bottom of the multi-layer stack, the metal plate at the bottom is removed from the discharge box 30 by the thrust of the reset plate 314 on the metal plates. 1 is discharged, and at the same time, the upper metal plate is blocked by the baffle 318. During the discharge process of the discharge box 301, the bottom metal plate deflects the reset plate 2 322 at a certain angle. At the same time, with the cooperation of the reset torsion spring 2 319, the bottom metal plate can be immediately closed after being moved out to prevent other metal plates from being moved out of the discharge box 301. At the same time, under the action of the reset torsion spring 2 319, during the movement of the metal plate, the reset plate 2 322 and the metal plate exert a certain downward pressure, and at the same time, the sponge pad 320 is fitted with the top of the metal plate. Impurities such as oil, dust, etc. on the metal plate can be removed through the sponge pad 320 to prevent these impurities from affecting the accuracy and surface quality of the product during the stamping process, thereby further improving the use effect of the device;

[0045] During the movement of the metal plate, the driving mechanism 310 is started to drive the multiple groups of rollers 309 to rotate. The rotation of the rollers 309 can reduce the contact friction during the movement of the metal plate, thereby further improving the movement effect. As the push plate 304 continuously moves the metal plate, the metal plate is limited by the limit plate 308, so that the metal plate is not easily deflected during the movement, so that the metal plate is moved to the accurate position of the stamping die 21, and the precision of the subsequent stamping is improved. Before this, the limit plate 308 is moved to drive the limit sleeve 305 to move, so that the distance between the two groups of limit plates 308 can be adjusted, so as to better adapt to the metal plates with different distances for limiting, thereby further improving the use effect of the device.

[0046] Then, the electromagnet 307 is energized to generate a magnetic attraction force to adsorb and fix the connecting plate 306, thereby fixing the limit plate 308. This fixing method is more flexible, practical, simple and convenient.

[0047] Until the push plate 304 pushes the metal plate to the position of the stamping die 21, and then the stamping operation is performed through the stamping mechanism 2. Through this operation, there is no need for manual loading. Through automated operation, the time for feeding and unloading can be greatly reduced, and production efficiency can be improved. There is no need to hire a large number of workers to complete these tasks, which reduces the company's labor costs. The equipment is more accurate in repetitive operations, reducing quality problems caused by human errors, and uniform feeding can ensure that there is enough material for each stamping, avoiding downtime and readjustment due to insufficient materials, thereby improving production efficiency. At the same time, the position accuracy of the metal sheet during displacement is improved, avoiding the probability of position distortion due to manual feeding, thereby improving the stamping quality and stamping effect of the metal sheet.

[0048] When the push plate 304 contacts the moving rod 410 while the reciprocating screw rod 302 is moving, the moving rod 410 is pushed to move, and the moving rod 410 drives the strip plate 411 to move, and the strip plate 411 is used to stretch the rope 407, and at the same time, the rope 407 slides on the surface of the limiting wheel 409, and the limiting wheel 409 not only plays a position support, but also reduces the friction force, and improves the smoothness of the movement of the rope 407. As the rope 407 is pulled, the top rod 402 is driven to move downward, and the moving frame 407 is driven by the top rod 402. 4 moves down synchronously, so that the moving frame 404 drives the roller 405 to move to the bottom of the inner cavity of the stamping die 21, without affecting the stamping operation. When the stamping is completed, the push plate 304 is reset in the opposite direction. At this time, the spring 2 412 rebounds and drives the strip plate 411 to move and reset. At the same time, the spring 1 408 rebounds and drives the ejector rod 402 to move up. The ejector rod 402 drives the moving frame 404 to move up, and then the stamping part can be ejected from the stamping die 21, thereby improving production efficiency, reducing personnel operation, thereby avoiding the risk of personal injury, and further improving the use effect of the device;

[0049] When the rectangular plate 403 moves upward, the touch switch 413 contacts the stamping die 21. The touch switch 413 can start the drive motor 2 406 and drive the roller 405 to rotate. The rotation of the roller 405 causes the workpiece to move automatically and enter the collection frame 501 along the contact plate 516 to collect the workpiece.

[0050] When the workpiece contacts the contact plate 516, the spring three 515 has a certain buffering effect, reducing the impact force of the workpiece contacting the contact plate 516, thereby preventing the workpiece from being deformed. As the reciprocating screw 302 rotates, it drives the spur gear mechanism 502 to rotate, and the spur gear mechanism 502 drives the chain mechanism 1 503 to rotate, and the chain mechanism 1 503 drives the guide rod 1 504 to rotate, and the guide rod 1 504 drives the helical gear mechanism 505 to rotate. As the helical gear mechanism 505 rotates, the guide rod 2 506 and the chain mechanism 2 507 are driven to rotate synchronously. The chain mechanism 507 rotates to drive the rocker arm 508 to rotate, and the movable rod 509 slides on the rocker arm 508 through the rotation of the rocker arm 508, and at the same time drives the sleeve 510 to slide on the surface of the sliding rod 1 511, thereby mobilizing the sliding rod 2 512 and the toggle plate 513 to swing on the U-shaped connecting frame, so that when the collection frame 501 collects the workpieces, it can avoid local accumulation and overflow, and more effectively utilize the space effect, without the need for manual intervention, reduce the labor intensity of the staff, further improve the use effect of the device, and meet the actual use needs.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
