DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model. Specific Embodiment 1

[0025] Please refer to Figures 1-3, the utility model relates to a feeding device for a stamping die, which comprises a workbench 1. A female die 2 is fixedly connected to the top of the workbench 1. A male die 3 is arranged on the top of the female die 2. A hydraulic telescopic rod 4 is fixedly connected to the center of the top of the male die 3. The top of the hydraulic telescopic rod 4 is fixedly connected to a fixed frame 5. The bottom of the fixed frame 5 is fixedly connected to the top of the workbench 1. Through holes 6 for passing through plates are formed on both sides of the female die 2. Mounting plates 7 are fixedly connected to the front and rear ends of the top of the workbench 1 and on both sides of the female die 2. A first motor 8 is fixedly connected to the bottom of the surface of the front mounting plate 7. The output shaft of the first motor 8 penetrates to the back of the mounting plate 7 and is fixedly connected to a first roller 9. A moving groove 10 is formed at the top between the front and rear mounting plates 7. The bottom of the inner cavity of the moving groove 10 is movably connected with a threaded rod 11 through a bearing. A threaded block 12 is threadedly connected to the surface of the threaded rod 11. A second motor 13 is fixedly connected to the back of the front threaded block 12. The output shaft of the second motor 13 is fixedly connected to a second roller 14. The back of the second roller 14 is movably connected with a support plate 15 through a bearing. The back of the support plate 15 is fixedly connected to the surface of the rear threaded block 12. Photoelectric sensors 16 are fixedly connected to the front and rear ends of the top of the female die 2 and on both sides of the through hole 6.

[0026] Specifically: Place the plate on the top of the auxiliary support roller 19 and the first roller 9, and then rotate the handwheel to drive the threaded rod 11 to rotate. The threaded rod 11 drives the threaded block 12 to move downward. The threaded block 12 drives the second motor 13 to move downward, so as to drive the second roller 14 to move downward, thereby clamping the plate. Then start the first motor 8 to drive the first roller 9 to rotate, and start the second motor 13 to drive the second roller 14 to rotate. The second roller 14 rotates relative to the first roller 9 to convey the plate. When the plate enters the inner cavity of the female die 2 and the signal of the photoelectric sensor 16 is blocked, it means that the plate is conveyed to the working position. At this time, the hydraulic telescopic rod 4 can be extended to drive the male die 3 to move downward for stamping work. And the stamped product directly falls into the pre-placed receiving box through the discharge port 18. After stamping is completed, continue the conveying work of the plate to perform continuous stamping work. Specific Embodiment Two

[0028] Please refer to Figures 1-3, on the basis of the first specific embodiment, legs are fixedly connected to the four corners of the bottom of the workbench 1. Anti-slip patterns are provided at the bottoms of the legs. A controller 17 is fixedly connected to the front end of the top of the workbench 1. The controller 17 is electrically connected to the electrical equipment through wires. A discharge port 18 is opened at the top of the workbench 1 and below the cavity of the female mold 2. A material receiving box is provided at the bottom of the discharge port 18. Auxiliary support rollers 19 are fixedly connected to both sides of the top of the workbench 1. The auxiliary support rollers 19 and the first roller 9 are in the same horizontal plane. The top of the threaded rod 11 penetrates through the top of the mounting plate 7 and is fixedly connected to a handwheel. An anti-slip sleeve is provided on the surface of the handwheel. Rubber sleeves are sleeved on the surfaces of the first roller 9 and the second roller 14. Anti-slip patterns are provided on the surfaces of the rubber sleeves.

[0029] Specifically: By providing the discharge port 18, the products completed by stamping can be directly and quickly discharged. By providing the controller 17, full-automatic control can be achieved. By providing the auxiliary support rollers 19, the middle support of the plate can be carried out, ensuring the stability of its transportation. By providing the handwheel, it is convenient to rotate the threaded rod 11.

[0030] During use, by placing the plate on the tops of the auxiliary support rollers 19 and the first roller 9, then rotating the handwheel to drive the threaded rod 11 to rotate, the threaded rod 11 drives the threaded block 12 to move downward, and the threaded block 12 drives the second motor 13 to move downward, so as to drive the second roller 14 to move downward, thereby being able to clamp the plate. Then, by starting the first motor 8 to drive the first roller 9 to rotate and starting the second motor 13 to drive the second roller 14 to rotate, the second roller 14 rotates relative to the first roller 9, and the plate can be transported. When the plate enters the inner cavity of the female mold 2 and the signal of the photoelectric sensor 16 is blocked, it means that the plate is transported to the working position. At this time, the hydraulic telescopic rod 4 can be extended to drive the male mold 3 to move downward for stamping work. The products completed by stamping directly fall into the pre-placed material receiving box through the discharge port 18. After the stamping is completed, continue the transportation work of the plate, and continuous stamping work can be carried out.

[0031] 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 spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
