Abstract
The invention provides a method for directly forming a cutter die by utilizing one-time etching and the cutter die formed by the method, and the method comprises the following steps: (A) selecting a metal plate; (B) forming two layers of anticorrosive photoresist on the metal plate and forming patterned lines after exposure and development; (C) etching the surface of the metal plate by spraying etching liquor to form a blade; and (D) stripping the anticorrosive photoresist. The blade part is formed by etching by using the two layers of the anticorrosive photoresist, grinding or polishing is not needed any more after etching, and the blade part does not need secondary etching, thus forming the cutter die with high accuracy, and the method can not only reduce the blade tolerance of the formed cutter die but also enhance the yield rate of the cutter die effectively.
Description
Technical field
The invention relates to the method for utilizing etching to form cutting die, particularly relevant for utilizing an etching directly to form the method for cutting die.
Background technology
The etching cutting die mainly is to be used to cut for example thin slice materials such as paper, film, foam, soft magnetism, photograph, skin, cloth, forms certain patterns or font, or goes out silhouette character pattern or font in the slice surfaces coining, is usually used in making card, photo album, packing timber etc.
Generally speaking, the method for manufacturing etching cutting die mainly is divided into two kinds.First kind is earlier at metal sheet surface, prints out one deck acid-proof ink lines according to required pattern or font, makes the metallic surface be divided into etching region and non-etching region.Behind the ink setting, metal sheet is soaked in the etching agent, the zone that the metallic surface is not printed on printing ink forms sunk part through the liquid medicine etching, and the zone that is printed on printing ink then forms salient without the liquid medicine etching.Afterwards, re-use shredder or milling machine machine and grind salient formation knife edge part.When metal was soaked in the etching solution, if printing ink line thickness deficiency, because the influence of lateral corrasion, printing ink itself can weaken avalanche because of anchorage force, and the fineness of printing ink lines is restricted.On the other hand, this kind method also is subject to the shredder size, can't produce meticulous pattern flexibly, and processing procedure is quite complicated.
United States Patent (USP) the 3rd, 850, No. 059 and Republic of China's patent disclose for No. 27573 utilizes the mode of spraying etching solution to carry out etching, earlier etch knife edge blank at metal sheet surface, after divesting printing ink or photoresist, partly carrying out the etching second time at the knife edge, formation can cut the knife edge of paper, but can influence printing ink or photoresist lines owing to spray the pressure and the lateral corrasion impact of etching solution, printing ink or the photoresist lines that therefore can't effectively control high-fineness carry out etching.In order to form the knife edge that can cut thin slices such as paper, must after divesting printing ink or photoresist, partly carry out the etching second time at knife edge blank.Yet, knife edge top is corroded in this meeting of etching for the second time, cause the inhomogeneous influence of tool-point height to cut effect, and this method still can't overcome the residual water resistance effect of etching solution, the knife edge and cutting die base junction still can be subjected to the influence of bottom etching, cause shortcomings such as high-fineness cutting die product yield reduction.
In view of this, still need a kind ofly can form the high-fineness cutting die, can avoid the method for shortcomings such as etching solution lateral corrasion and water resistance effect simultaneously.
Summary of the invention
The invention provides a kind of method of utilizing an etching directly to form cutting die, comprise that (A) selects sheet metal; (B) form two layers of anticorrosive photoresist in this metal sheet, after exposure, development, form the one patterned lines; (C) this metal sheet surface is sprayed etching solution and carry out etching, form the knife edge; And (D) divest this anticorrosive photoresist.The method of utilizing an etching directly to form cutting die of the present invention is to use two layers of anticorrosive photoresist, etching forms knife edge part, do not need to grind again or polish processing after the etching, also need partly not carry out second etch at the knife edge, can form cutting die with high-fineness, not only can reduce the blade tolerance of the cutting die that forms, more can effectively improve the cutting die yield.
The present invention provides a kind of cutting die that utilizes an etching directly to form again, comprises the cutting die base and the knife edge that is formed at this cutting die base, and this knife edge top end surface keeps the former material epidermis of metal former state.
