Flat knife die composed of upper die with integral structure and lower die

Abstract

The invention discloses a flat knife die composed of an upper die with an integral structure and a lower die. The upper die comprises an upper die base plate and a blade, wherein the blade is installed on the upper die base plate and perpendicular to the upper die base plate. The upper die base plate is a steel plate, and the blade is directly and integrally machined on the steel plate of the upper die base plate. A positioning column is arranged on the steel plate. Material guiding mechanisms are respectively arranged on two sides of the upper surface of a lower die base plate, the upper surface of the lower die base plate is provided with a paper material layer for adjusting the material height, a cover plate is arranged on the paper material layer, and the paper material layer and the cover plate are located between the material guiding mechanisms. The blade position on the upper die can be ensured well, displacement, deformation and other defects do not occur, and the machining accuracy is ensured. In addition, the material height of the lower die can be conveniently adjusted through the paper material layer so as to solve the problem that the blade of the upper die is uneven.

Description

technical field [0001] The invention relates to the improvement of the structure of the knife die, in particular to a flat knife knife mold composed of an upper mold and an upper mold with an integral structure, and belongs to the technical field of the flat knife knife mold. [0002] Background technique [0003] Flat knife die is a common mold for processing thin sheets, such as aluminum foil, PET materials for computers, dustproof PC film for electronic products speakers, etc. The flat knife die in the usual sense is the upper die, that is, it is located above the material to be processed. The upper die is mainly composed of a base plate and a blade. The blade is embedded in the slot on the base plate and exposes an appropriate height. The arrangement shape of the blade determines the thin type. The blanking shape of the sheet. During processing, the thin sheet is fed into the pressing seat directly below the upper die through a special feeding mechanism, and then drive...

AI Technical Summary

Problems solved by technology

If the positioning hole is directly processed on the press seat, the structure of the press seat is easy to be damaged, and because some upper dies do not need the positioning hole of the press seat, if the positioning hole is processed on the press seat, it will limit the application range of the press seat

At the same time, since the pressure seat is integrated with the processing equipment, it is inconvenient to disassemble, and it is also inconvenient to maintain when the pressure seat fails.
