Embodiment Construction

[0030] Such as figure 1 Shown, the method for multiple etching of the present invention direct forming knife mold comprises the following steps:

[0031] Select Sheet Metal Steps

[0032] Select sheet metal, such as heat-treated high-carbon steel, and cut it to size.

[0033] Prerequisite steps

[0034] Degrease and clean steel plates of appropriate dimensions.

[0035] Lamination step

[0036] After degreasing and cleaning the steel plates that have been cut into applicable sizes, the front and back of the steel plates are pressed with a film layer after degreasing and cleaning.

[0037] The backside film layer is any acid-resistant film, not specifically a photoresist film, to prevent etching.

[0038] The front film layer is a thin film such as a photoresist film that can be transferred to the negative of the cutting image and can produce chemical changes after exposure and development to block the effect of etching.

[0039] Make Die-Die Negatives

Abstract

The invention discloses a technique that directly forms cutter-mould by complex etching and its device. The invention is for enhancing the productivity, lowering the production cost, skipping the grinding process, enhancing the product quality, reducing the pollution, offering a cutting and pressing tools and its device. The technique consists of following steps: metal plates selection, reprint screen, first etch after reprinting with etch liquor on light cover, de-film along the cutting line, fire etch and polish-brush on the base surface and tool base; reprint the screen by exposing on the film made with pressing film and the produced tool mould film, develop the screen on the negative catalyzer film; the fine etch steps is removing the edge lines on both side on top of the tool base making the blade into narrow angle small arc blade; the device consists of reprint mechanism, etch recycle mechanism, defilm filter mechanism, complex etch shaping mechanism and polish-brush mechanism.

Description

technical field [0001] The invention belongs to a method and a device for forming a knife for cutting and stamping, in particular to a method and a device for re-etching and directly forming a knife mold. Background technique [0002] In the manufacture of cards, photo albums, packaging boxes, preschool education materials, arts and crafts, housekeeping, patchwork, advertisements, posters, window or stage design, etc., it is necessary to use thin stamping dies (commonly known as knife dies) on thin sheet materials, such as paper, Plastic, sponge, cardboard, corrugated paper, soft magnetic, photo paper, cloth, leather, iron sheet, cork for cutting or forming. [0003] The known knife molds are mainly divided into two series. One is shaped by blades and planted on wood, plastic or steel plates. It includes plastic laser knife molds, wire cutting knife molds, plastic knife molds, etc., commonly known as traditional knife molds. . [0004] The other is to etch the knife edge o...
