Flat cutter cutting die which is composed of upper die and lower die and is capable of avoiding displacement of blade

Abstract

The invention discloses a flat cutter cutting die which is composed of an upper die and a lower die and is capable of avoiding displacement of a blade. The upper die comprises an upper die bottom plate and the blade, and the blade is mounted on the upper die bottom plate and is perpendicular to the upper die bottom plate. The upper die bottom plate is fixedly provided with a steel plate, the blade is directly machined and formed on the steel plate, and a positioning column is arranged on the steel plate. A positioning hole corresponding to the positioning column is formed in the upper surface of a lower die bottom plate, and the two sides of the upper surface of the lower die bottom plate are respectively provided with a material passing guide mechanism. According to the flat cutter cutting die, the position of the blade on the upper die can be well guaranteed, the defects of displacement, deformation and the like can be overcome, and the machining precision is guaranteed. Due to the fact that the lower die is detachably mounted on a pressing seat, when the lower die is not needed, machining can be conducted on the pressing seat directly, even though the lower die is damaged, replacing and maintaining are convenient compared with the pressing seat, and therefore the using cost is lowered.

Description

technical field [0001] The invention relates to the improvement of the die structure, in particular to a flat die die consisting of upper and lower dies which can avoid blade displacement, and belongs to the technical field of die dies for flat dies. [0002] Background technique [0003] Flat-knife dies are common molds for processing thin sheets, including aluminum foil, PET materials for computers, and dust-proof PC films for speakers of electronic products. The usual meaning of the flat knife die is the upper die, which is located above the material to be processed. The upper die is mainly composed of a bottom plate and a blade. The blade is embedded in the slot on the bottom plate and exposed to an appropriate height. The arrangement of the blade determines the thin The blanking shape of the sheet. During processing, the thin sheet is sent to the press seat directly below the upper die through a special feeding mechanism, and then the upper die (knife edge facing down...

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.
