Abstract

The utility model relates to a punching die which is used for punching the product boundary material in the punching production and comprises an upper die (1) and a lower die (2), wherein the upper die (1) is installed with a detachable upper die tool bit comprising a plurality of upper die tool bits (1.1); the outer edge of the detachable upper die tool bit is matched with the outer edge of the product; the lower die (2) is installed with a detachable lower die tool bit comprising a plurality of lower die tool bits (2.1); the lower detachable die tool bit is matched with the detachable upper die tool bit; two ends of the lower die (2) are provided with punch fixing pedestals (2.2); the punch fixing pedestals (2.2) are provided with punches (2.3); and the periphery of the detachable lower die tool bit is provided with a plurality of boundary material cutting tool bits (2.4). The punching die has low using cost, accurate positioning and high production efficiency, and is convenient to maintain.

Description

Die cutting die

(1) technical field

The utility model relates to a kind of die cutting die, is used for die-cut production and carries out die-cut to the product rim charge.

(2) background technology

At present, the die-cut of routine all is monolithic construction with the mould cutter head, be that cutter head and whole template connect together, thereby in die-cut process, can not regulate die-cut gap, make product after die-cut finishing, also need to carry out artificial deburring, and when a certain position of monoblock type cutter head is damaged, need integral replacing, cause follow-up working service cost higher; Simultaneously, conventional die cutting die all is to rely on profile to position, not only need to expend the more time to position, and alignment error easily; In addition, the rim charge that traditional die cutting die is die-cut after finishing connects together, and operating personnel's difficulty comparatively when peeling off these side crops takes time and effort.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of easy to maintenance, use cost is low, accurate positioning and the high die cutting die of production efficiency.

The purpose of this utility model is achieved in that a kind of die cutting die, described mould includes upper die and lower die, a complete mould is synthesized in described upper die and lower die pairing, the removable cutter head of patrix is installed on the described patrix, the removable cutter head of this patrix is made of some patrix cutter heads, and the outer rim and the product outer rim of the removable cutter head of this patrix are complementary, the removable cutter head of counterdie is installed on the described counterdie, the removable cutter head of this counterdie is made of some counterdie cutter heads, and removable cutter head of this counterdie and the removable cutter head of patrix are complementary, described counterdie two ends are provided with the drift holder, the drift holder is provided with drift, and the removable cutter head periphery of above-mentioned counterdie is provided with some side cut material cutter heads.

The beneficial effects of the utility model are:

When tool bit abrasion need be changed, only need change the cutter head of this damage, and need not to carry out integral replacing, reduced the follow-up maintenance use cost; Increased locating hole product is positioned, not only the handled easily personnel operate, and have reduced the operating time, and the location is more accurate; Simultaneously, be provided with the material cutter head of cutting edge, in die-cut, side crops cut off, make things convenient for the subsequent operation personnel to carry out strip operation, reduced the working time, intensity, improved operating efficiency at the cutter head periphery.
