Description

Flat cutting die with insert block structure

Technical Field

The utility model relates to a cross cutting equipment technical field, more specifically say, it relates to a flat cutting die with structure of inserting.

Background

The flat cutting die is a common die for processing thin sheets, and the thin sheets comprise aluminum foils, PET (polyethylene terephthalate) materials for computers, dustproof PC (polycarbonate) films for loudspeakers of electronic products and the like. The flat cutting die is generally positioned above a material to be processed and mainly comprises a bottom plate and blades, wherein the blades are embedded in clamping grooves in the bottom plate and exposed out of proper heights, and the arrangement shape of the blades determines the die cutting shape of the thin sheet.

The edge of current flat cutting die is in order to guarantee die-cut product neatly clear and cut off fast, and the sharpness of flat cutting die's blade design is just fragile, and the blade easily takes place wearing and tearing or rupture owing to lack the protection architecture during die-cut to, when die-cut thicker material, for example: when the thickness of the sheet material exceeds 0.25mm, the edge of the punching material is easy to bulge and turn over, and the die cutting quality is influenced.

In the prior art, the material to be punched is generally flattened by using the padding knife cotton, but when the material with a hard and thick surface is punched, the hardness of the foam is low, the product cannot be well compacted, and the conditions of bulging and flanging of the edge of the punched product cannot be eliminated.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a flat knife mold with structure of inserting, its advantage is to have blade edge protection architecture, and the difficult book decreases of blade edge, can die-cut material that thickness is big, the surface is hard, and the edge of die-cut product levels, and is die-cut effectual.
