Aperture punching and forming integrated grading die

Abstract

The invention discloses an aperture punching and forming integrated grading die. The grading die includes an upper die body, a lower die body, a convex die body, a concave die body and a secondary precise guide mechanism; the convex die body is arranged in the upper die body; the concave die body is arranged in the lower die body; and the upper die body and the lower die body are connected together through the secondary precise guide mechanism. The aperture punching and forming integrated grading die can perform punching for 500 times per minute on a high speed punching machine, can allow once punch-forming of products without secondary machining, is high in production efficiency in aperture machining, and is low in cost; and in a high speed punching process, a small punch will not break off, and the service life is long.

Description

technical field

[0001] The invention relates to the technical field of molds, in particular to an automatic high-precision progressive mold integrating small hole punching and forming. Background technique

[0002] At present, in the production process of multiple small holes with small spacing between holes, three processes can be used to achieve: 1) single-process die stamping forming process: use multiple pairs of single-process dies to stamp the small holes, and then use a pair of single-process dies to form small holes. Products required for die stamping; 2) Laser etching process: first use single-process molds or other molds to manufacture the required products into semi-finished products, and then use the high heat energy generated by the laser generator to etch the semi-finished products. Forming; 3) Drilling and forming process of high-speed drilling machine: drilling and forming small holes one by one. The common disadvantages of the above processes are: long proc...
