Description

  The present invention relates to a die cutter, and more particularly to a die cutter formed directly by a single etching.

  Etching / Die Cutter is mainly used for cutting sheet materials such as paper, film, foam, soft magnet, photograph, leather, cloth, etc., forming a predetermined pattern or letter shape, or embossed character pattern on the sheet surface Or, by embossing the character shape, it is often used for making cards, albums, packaging materials, and the like.

  Generally, there are mainly two methods for manufacturing an etching die cutter. One method divides the metal surface into an etched area and a non-etched area by printing an acid-resistant ink line on the surface of the metal plate according to a necessary pattern or shape, and after the ink is dried, the metal plate is By immersing in the etching chemical solution, the area where the ink on the metal surface is not printed is formed as a depressed portion by etching the chemical solution, and the region where the ink is printed is not etched by the chemical solution, so that a protrusion is formed. It is a method. Thereafter, the protruding portion is formed as a blade portion by a polishing machine or a milling machine. When the metal is immersed in the etching solution, if the width of the ink line is insufficient, the supporting force of the ink itself is weakened and collapses due to the influence of side etching, and the accuracy of the ink line is limited. Furthermore, since such a method has a limitation on the size of the polishing machine, a smooth and delicate pattern cannot be created, and the manufacturing process may be very time-consuming.

  In order to solve the drawbacks of the above methods, other methods have been sought. The other method will be described with reference to FIGS. 12A to 12D. The other method is a method in which secondary etching is performed by spraying an etching solution. As shown in FIG. 12A, first, a blade prototype 940 is etched on the surface of the metal plate 910, and after removing the ink or resist 920 as shown in FIG. 12B, the blade prototype 940 is removed as shown in FIG. 12C. A second etching is performed on the portion of the blade 950, and a blade 950 capable of cutting the paper is formed by a polishing process as shown in FIG. 12D.

  However, since the pressure of spraying the etching liquid and the impact caused by side etching affect the ink or resist line 920, the high-precision ink or resist line 920 cannot be effectively controlled to perform etching. Further, in order to form a blade 950 that can cut a sheet such as paper, after removing the ink or resist 920, a second etching must be performed on the portion of the blade prototype 940. However, the tip 950a of the blade 950 is eroded by this second etching, and the metal material (that is, the surface material of the metal plate 910) is destroyed, so the height of the tip 950a of the blade 950 and the entire blade 950 is not uniform ( 12C), which affects the cutting effect, increases the polishing process, and increases the manufacturing cost. Moreover, in the polishing process, only the tip 950a of the blade 950 is processed, not the height of the entire blade 950. Furthermore, since the conventional method cannot overcome the water stop effect due to the remaining etching solution, the connecting portion between the blade 950 and the die cutter base 900 is affected by bottom etching, and the yield of the high-precision die cutter 90 is reduced. There was a drawback of end.

  For this reason, while forming a highly accurate die cutter, providing the die cutter which can overcome the faults, such as the side etching by an etching liquid, and the water stop effect, has become an important subject.

  In order to solve the above problems, the present invention provides a die cutter including a die cutter base and a blade formed on the die cutter base, and the blade tip surface is a metal material of the die cutter base.

  Furthermore, the present invention provides a reconfigurable die cutter set including one or a plurality of the die cutters and a soft magnet sheet.

  Furthermore, in the present invention, the die cutter, a concave plate corresponding to the die cutter plate, and a foldable plastic plate for adhering the die cutter plate and the intaglio plate, the die cutter plate is a blade and A die cutter set is provided in which a trench is formed at a location corresponding to the projection of the die cutter plate of the concave plate.

  Furthermore, the present invention provides a die cutter set comprising a die cutter base having both surfaces and a blade formed on both surfaces of the die cutter base, the tip surface of the blade being a metal material of the die cutter base.

  The die cutter according to the present invention reduces the blade edge tolerance of the formed die cutter and effectively improves the yield of the die cutter as compared with the conventional technique.
