Abstract
The invention discloses an anti-bounce insert structure for punching of thin materials. The anti-bounce insert structure comprises a lower die upper layer insert and a lower die lower layer insert matched with the lower die upper layer insert. The upper end face of the lower die upper layer insert is provided with a knife edge straight hole. A discharge hole for normally discharging chippings of waste materials is formed between the bottom end of the knife edge straight hole and the lower end face of the lower die upper layer insert in a penetrating mode. Straight clamping strips for clamping the waste materials are evenly distributed on the periphery of the hole wall of the knife edge straight hole in the axial direction. The side walls of the straight clamping strips are aligned at the hole wall of the knife edge straight hole. After passing through the knife edge straight hole and falling into the discharge hole, the waste materials are clamped by the straight clamping strips on the side wall of the discharge hole, and therefore the waste materials will not bounce out of the knife edge straight hole. The anti-bounce insert structure is simple in structure and prevents the waste materials from bouncing.

Wherein, the cross section of described straight body card article is isosceles trapezoid, and the angle between the two side of described straight body card article and the hole wall of described material-dropping hole is greater than 90 degree.
Wherein, described counterdie lower floor enters on the upper surface of piece also to run through and be provided with screwed hole, described screwed hole be arranged on the counter sink that described counterdie upper strata enters on piece and match.
Wherein, the degree of depth in the straight body of described edge of a knife hole is less than or equal to 2.0MM,
Wherein, the angle between described material-dropping hole and the hole wall of described material-dropping hole and the hole wall in the straight body of described edge of a knife hole coaxial with the straight body of described edge of a knife hole is less than or equal to 5 degree,
Wherein, described counterdie lower floor enters up/down perforation on piece upper surface and is provided with the through hole coaxial with described material-dropping hole, and the diameter of described through hole is greater than the maximum gauge of described material-dropping hole.
Wherein, the cross section of the described edge of a knife straight body hole and the described material-dropping hole setting of being rectangle.
Beneficial effect of the present invention: the present invention includes a kind of thin material punching bounce-proof and enter block structure, comprising that counterdie upper strata enters piece and enters with described counterdie upper strata the counterdie lower floor that piece matches enters piece, on Ru Kuai upper surface, described counterdie upper strata, be provided with the straight body of edge of a knife hole, between the bottom in the straight body of described edge of a knife hole and Ru Kuai lower surface, described counterdie upper strata, run through the material-dropping hole being provided with for the normal exfoliation of waste material, the surrounding of the hole wall of described material-dropping hole is axially evenly equipped with for blocking the straight body card article of waste material, and the hole wall in the sidewall of described straight body card article and the straight body of described edge of a knife hole aligns.The straight body card article being arranged on described material-dropping hole sidewall after straight body hole falls into material-dropping hole by the edge of a knife when waste material blocks, thereby makes waste material can not jump out the straight body of edge of a knife hole, and the present invention is simple in structure, prevents that waste material from jumping material.
