Detailed Description

The preferred mechanisms and methods of motion realization of the present invention are further described below in conjunction with the figures and the detailed description.

As shown in fig. 1 and 2, a stamping die structure for stamping with a plurality of blanking sections includes an upper die, a lower die and a trimming punch 12.

The upper die comprises an upper die base 1, an upper backing plate 2, an upper clamping plate 3, a stop plate 4, a stripper plate 5, an equal-height sleeve 11 and a guide pillar 13; the trimming punch 12 and the guide post 13 are assembled in a hole of the upper clamping plate 3, and the stop plate 4 and the stripper plate 5 are locked with the upper die holder 1 through the equal-height sleeve 11 by nuts. The guide posts 13 serve to guide the upper and lower dies.

The shape of the cut edge of the end face of the cutting punch 12 may be regular or different according to the processing requirements of the product.

The lower die comprises a lower die plate 6, a lower cushion plate 7, a lower die base 8, a lower cushion block 9, a lower supporting plate 10 and a punching insert 15; the punching insert 15 is assembled in the lower template 6, the lower template 6 and the lower cushion plate 9 are locked with the lower die base 8 through nuts, the lower die base 8 is locked with the lower cushion block 9 through nuts, and the lower cushion block 9 is locked with the lower support plate 10 through nuts.

The lower die is provided with a blanking hole, the position of the trimming punch 12 corresponds to the blanking hole, a to-be-blanked part 14 which does not completely cover the blanking hole is arranged between the upper die and the lower die, and the trimming on the trimming punch, which is close to the end face of one side of the to-be-blanked part 14, is provided with a punch fillet 16.

The punch head fillet 16 is a fillet with the radius of R0.2-0.4 mm. If the thickness is less than 0.2, no practical processing significance is realized, and if the thickness is more than 0.4, the bright surface of the cutting section cannot be ensured to be more than 2/3 of the material thickness.
