Detailed Description

The present invention will be further described with reference to the following examples.

The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. The condition in the embodiment can be further adjusted according to concrete condition the utility model discloses a it is right under the design prerequisite the utility model discloses a simple improvement of method all belongs to the utility model discloses the scope of claiming.

Referring to fig. 2-4, a compact die for processing inner punched holes includes an upper die holder 1 and a lower die holder 2, the upper die holder 1 and the lower die holder 2 are in sliding fit with a guide pillar 4 through a guide sleeve 3, and the compact die for processing inner punched holes is characterized in that: the bottom of the upper die holder 1 is fixedly provided with an ejector block 19 and an anti-shaking cylinder 5, the bottom of the upper die holder 1 is also connected with a stripper plate 6 through an inner guide pillar and an inner guide sleeve, a nitrogen spring 7 is arranged between the stripper plate 6 and the output shaft of the anti-shaking cylinder 5, a press plate 8 is fixedly arranged on the output shaft of the anti-shaking cylinder 5, and the bottom of the press plate 8 is fixedly connected with a driving block 9; the top of the lower die holder 2 is fixedly provided with a nitrogen spring 10, and the top of the nitrogen spring 10 is fixedly provided with a nitrogen ejector rod 11; the top of the lower die holder 2 is further connected with a floating lift 12 through a nitrogen spring 20, the floating lift 12 is connected with a knife edge slide block 13 and a punch slide block 14 in a sliding manner, a knife edge insert 15 is fixedly installed on the inner side of the knife edge slide block 13, a punch 16 is fixedly installed on the outer side of the punch slide block 14, the punch slide block 14 is further connected on a conical slide block holder 17 in a sliding manner, and the conical slide block holder 17 is fixedly installed on the upper die holder 1; the driving block 9 is in sliding fit with the knife edge sliding block 13 through an inclined plane, the top end of the nitrogen ejector rod 11 is matched with the bottom end of the opposite ejection block 4, and the knife edge insert 15 is matched with the punch 16.
