[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Depend on Figures 1-9The present invention includes a body 1, a frame 11 mounted on the top of the body 1, a hydraulic rod 12 mounted on the top of the frame 11, two stamping columns 13 mounted on the horizontal plate at the bottom of the hydraulic rod 12, and a die-cutting knife 14 mounted on the bottom of the stamping columns 13. A placement seat 15 is mounted on the top of the body 1 via a drive assembly 2. A lifting plate assembly 3 is installed inside the placement seat 15. A protective assembly 4 is connected between the placement seat 15 and the frame 11. The protective assembly 4 includes a protective cover 41. Four guide rods 42 passing through the frame 11 are fixed on the top of the protective cover 41. Springs A43 are connected to the top of the guide rods 42 and the frame 11. The protective cover 41 is pierced by two stamping columns 13. An inclined block 45 is fixed to the protective cover 41. An inclined block 44 is fixed on both sides of the placement seat 15. The bottom surface of the inclined block 44 can fit with the inclined block 45, and at this time, the protective cover 41 is in contact with the surface of the placement seat 15.

[0030] As described above, when the drive assembly 2 moves the placement seat 15 to the processing station, the inclined surfaces of inclined block 2 44 and inclined block 1 45 interact with each other. When the inclined surfaces of inclined block 2 44 and inclined block 1 45 are fully in contact, the protective cover 41 is pushed down along the guide rod 42 and slowly comes into contact with the surface of the placement seat 15, causing the spring A43 to be compressed. The protective cover 41 will also slide outside the stamping column 13. When the stamping column 13 drives the die-cutting knife 14 to press down, the protective cover 41 and the surface of the placement seat 15 are tightly in contact to form a closed protective space, effectively preventing the risk of debris splashing and accidental contact during processing. Then, the hydraulic rod 12 is activated to make the die-cutting knife 14 descend to perform rapid die-cutting on the sheet. At the end of processing, inclined block 1 45 disengages from inclined block 2 44, and the protective cover 41 is reset by the spring A43. A silicone pad can be designed at the bottom of the protective cover 41.

[0031] The protective component 4 also includes a ring 46 fixed to the guide rod 42, which rests against the top of the inside of the frame 11 in the initial position.

[0032] As described above, the ring 46 can ensure that the guide rod 42 is in a fixed initial position, and ensure stable contact between the inclined block 2 44 and the inclined block 1 45.

[0033] The drive assembly 2 includes protrusions 21 fixed on both sides of the placement base 15. The protrusions 21 are threadedly connected to the lead screw 22. The lead screw 22 is rotatably installed on the top two side support plates of the machine body 1. A motor 23 that drives the lead screw 22 to rotate is installed on one side support plate. A convex slider 24 is installed at the bottom of the placement base 15. The convex slider 24 slides in the slide rail on the surface of the machine body 1.

[0034] As further detailed above regarding the drive assembly 2, when the motor 23 drives the lead screw 22 to rotate, the protrusion 21 drives the placement seat 15 to move precisely along the slide rail via threaded transmission. The cooperative design between the convex slider 24 and the slide rail ensures the smooth movement and positioning accuracy of the placement seat 15, effectively avoiding positional deviations during processing. This drive structure features high transmission efficiency, accurate positioning, and smooth operation, meeting the processing requirements of housings of different specifications and preventing the hands from being positioned below the die-cutting blade during loading and unloading, thus enhancing safety.

[0035] The lifting plate assembly 3 includes a lifting plate 32 that interacts vertically inside the placement seat 15. Two sliding rods 33 are symmetrically fixed at one end of the bottom of the lifting plate 32, and another sliding rod 33 is fixed at the center of the other end of the bottom. The sliding rods 33 pass through the placement seat 15 to form a sliding connection. A spring B34 is connected to the bottom of the sliding rod 33 and the placement seat 15. A sliding wheel 36 is installed at the bottom of the sliding rod 33. An elastic rubber pad 16 is adhered to the inner wall of the placement seat 15. The rubber pad 16 contacts the side of the lifting plate 32. The sliding wheels 36 roll on the top of the support platform 31. The top of the support platform 31 is divided into two support surfaces, high and low, by an inclined plane. When the placement seat 15 is inside the frame 11, the sliding wheel 36 is located on the lower support surface of the support platform 31.

[0036] With the design of the lifting plate assembly 3, in order to ensure the stability of the sheet material during processing, the sheet material is placed on the lifting plate 32 inside the placement seat 15. The placement seat 15 is located outside the frame 11. The sheet material is attached to the inner wall of the placement seat 15 by the rubber pad 16, so that it will not shake during die cutting. When placed, the sliding wheel 36 is located on the low support surface of the support platform 31, and the lifting plate 32 is attached to the inner bottom surface of the placement seat 15. After processing, the sheet material is divided into the required size and the cut-off edge, which makes it difficult to remove. At this time, during resetting, the placement seat 15 can be moved outward a little more until all three sliding wheels 36 are moved to the high support surface of the support platform 31, so that the lifting plate 32 moves upward through the sliding rod 33, pushing out the edge and the sheet material together, making it easy to remove.
