Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.

Example (b):

referring to fig. 1-7, the present embodiment is an integrated die structure for punching and trimming a ring-shaped member, and includes a lower support plate 1, a lower die punch 2 disposed on the lower support plate 1, an outer stripper plate 3 disposed on the lower support plate 1 and located on the periphery of the lower die punch 2, an inner stripper plate 4 disposed above the lower die punch 2 and corresponding to the lower die punch 2 in a matched mold copying manner, an upper die punch 5 disposed inside the inner stripper plate 4, and an upper die cutter plate 6 disposed outside the inner stripper plate 4 and corresponding to the outer stripper plate 3 in a matched mold.

The middle part of the lower die punch 2 is provided with a through punching position 21, and the upper die punch 5 is correspondingly matched with the punching position 21. The punching sites 21 are circular holes in this embodiment.

The lower die punch 2 has a flange 22 at the upper edge of the inner periphery thereof, the upper die punch 2 has a bottom surface exposed to the bottom surface of the inner stripper plate 4, and the lower die punch 2 is slidably fitted along the flange 22. When the material sheet 7 is subjected to the stamping acting force of the upper die punch 5, the material sheet 7 is retracted in the space between the lower die punch 2 and the flange part 22, and the damage to the appearance of the punched hole in the punching process of the material sheet 7 is effectively avoided.

And a height difference is formed between the surface of the outer stripping plate 3 and the top end of the lower die punch 2, and the inner wall of the upper die cutter plate 6 is attached to the surface of the outer stripping plate 3 along the edge of the outer wall of the lower die punch 2 in a punching way.

The lower support plate 1 is internally provided with a central hole 11 communicated with the punching position 21. The inner wall of the inner stripper plate 4 is flush with the flange portion 22 of the lower die punch 2.

Interior take off board 4 is the loop configuration, and the periphery of interior take off board 4 is equipped with a plurality of last mould cutter boards 6 along its edge profile modeling laminating concatenation, and last mould cutter board 6 encloses to close along the periphery quartering position concatenation of interior take off board 4 and is the square slab structure in this embodiment. The structure spliced by the upper die cutting knife board 6 is easier to replace and maintain, and the punching height of the upper die cutting knife board 6 is convenient to adjust.
