Description

  The present invention relates to a punching die, and more particularly to a metallic punching die formed by etching.

  A conventional die formed by etching is formed by printing a pattern imitating a die on the surface of a metal plate using ink, removing the ink after etching, and polishing with a polishing machine. Since the cutter part that has not been etched by polishing is polished and the upper width is narrow, it is formed so as to exhibit a wide pyramid shape toward the bottom, and a sharp tip is formed at the upper apex, Achieve the cutting function.

The punching die is convenient to manufacture because the cutter part and the base are integrally formed. Further, this type of punching die is certainly more convenient than a punching die in which a cutter piece processed and formed through conventional polishing is provided at the bottom of the groove of the cut line.

However, the tip of the cutter part that is formed by etching always has a certain width due to the coating of the ink, and the line of the cutter part that has an incomplete saw-tooth shape formed on both sides is the base. (See 30 in FIG. 3). Therefore, the die cannot be completed unless the tip of the cutter portion is polished using a polishing machine or a milling plate.

In addition, since the polishing process must be performed, the distance B between the cutter part line and the cutter part line, and the angle formed by the opposing cutter parts use a polishing machine in the polishing process, both polishing. Limited by the size of the machine head.

When the polishing machine cannot polish, there are problems such as poor polishing or damage due to polishing. In addition, other problems such as an increase in processing speed, processing cost, defective product rate, and loss of the aesthetics of the etching die are conceivable.

  Further, in the conventional punching die, the tip of the cutter portion is polished by adjusting a polishing machine with a computer. Therefore, if the shape of the die is different, the computer program is different, and the polishing machine must be adjusted and processed by the program every time according to each die, so that the manufacturing efficiency is lowered. At present, there is a demand for cutting dies with different sizes in the market, so the conventional cutting dies have been a heavy burden for manufacturers.

In addition, the conventional punching die has a sharp apex of the cutter part to be formed, so that it is easily damaged in the polishing process and the quality of the product is deteriorated. Become.

Therefore, the present invention is capable of forming any die according to demand without adjusting the process by the die by performing etching on the metal plate a plurality of times, and the cutter portion having a slight width at the tip. It is an object of the present invention to provide a punching die capable of forming the shape.

  As a result of intensive research in view of the drawbacks found in the prior art, the present inventor has made a base made of a metal plate, a photoresist provided on an etching surface above the base, and a pattern to be etched, and a photoresist. The present invention was completed based on such knowledge, focusing on the point that the problems of the present invention can be solved by a punching die comprising a cutter part formed by microetching.

The present invention will be specifically described below.
The punching die according to claim 1 is provided with a base made of a metal plate material, a photoresist provided on an etching surface above the base, and a cutter formed by micro-etching after washing the photoresist. A part.

A punching die described in claim 2 includes a cutting edge in which the cutter portion in claim 1 is formed by microetching, and a line formed by spraying an etching solution.

In the punching die described in claim 3, the base in claim 1 is not limited in thickness.

According to a fourth aspect of the present invention, the die according to the fifth aspect is made of a film in which the photoresist according to the fifth aspect has an insulating effect after the exposure and development.

The punching die described in claim 5 has a foamed styrene or a thin film layer approximating to a layer of foamed styrene for the purpose of protecting the cushioning material and safety on the base in claim 1.

  The cutting die of this device does not need to adjust the manufacturing process every time the die shape is different, so it can be applied to a wide range of products, the production efficiency is increased, the polishing process is reduced, and the cost is reduced. Have.

Since the cutting die of this device is formed with a thin arc at the top of the cutter part, the line of the cutter part and the object to be cut are in close contact, and are not easily deformed or damaged by external force. Even if it is cut, it is not easily damaged or worn by impact, and has the effect of extending the service life of the product.

  This device provides a punching die that forms a cutter part having a slight width at the tip by forming any die according to demand by etching a metal plate a plurality of times. A metal plate material comprising: a base made of a metal plate material; a photoresist provided on an etching surface above the base, to which a pattern to be etched is transferred; and a cutter portion formed by micro-etching after washing the photoresist. The cutter part formed by transferring the design to the photoresist and etching the first time is about 1/5 to 1/10 the thickness of the conventional cutter part, and the top of the cutter part is already The ridgeline of the cutter part is also formed smoothly. Therefore, when the photoresist is washed and microetching is performed, both sides of the cutter part are removed, the tip part is further formed thinly, the base and the cutter part are formed so as to form a substantially right angle, and the etching solution is A die that flows along the ridgeline of the cutter portion and the base and the cutter portion in which the ridgeline and the base are reinforced can be quickly and easily completed.

Also, instead of the conventional polishing method, the top of the cutter part is thinly formed by microetching so that it is slightly arced, and the distance formed between the ridge line of the cutter part and the ridge line of the cutter part is reinforced and face each other The angle formed by the cutter portion is reduced, achieving the purpose of cutting, reducing the burden of polishing, and achieving the purpose of simplifying the process.
The punching die will be described below with specific examples.

  As the punching die of this device, a material suitable for the material of the cutting tool such as steel is selected, but this is not restrictive. Further, the thickness of the punching die is determined by the thickness of the object to be cut and is not limited, and the height is determined to be a height that maintains the base.

After performing the pre-process on the metal plate material, the photoresist 10 is stuck on both sides. Thereafter, the etching design film is transferred to the photoresist 10 and the first etching such as exposure and development is performed.

When the etching solution is pressurized and atomized and then sprayed from above the surface to be etched toward the metal plate surface, the metal plate has a plurality of recesses, a cutter portion protruding on the base, and the photoresist 10. A vertex with a stick is formed. The angle formed by the side wall of the ridge line of the cutter part and the base 20 is slightly larger than the right angle.

After the photoresist 10 is washed, a small amount of low-pressure etching gas is blown above the ridgeline of the cutter portion to perform the second etching. After performing micro-etching, the etching solution mixed along the ridge lines 271 and 272 of the cutter part formed on both sides from the top of the cutter part settles toward the bottom part, and a part of the volume is between the cutter part and the base. Then, the cutter part and the base are reinforced. Moreover, a part flows toward the recessed part of a base, and the base which was not formed in the plane by the 1st etching is formed flat.

Final polishing, anti-oxidation treatment, cutting, pressurization to protect from external force, die cutting, and foamed polystyrene 50 is provided for safety to complete the punching die.

The devices may be partially formed, combined or formed as a single surface, or formed as a continuous die mounted on a pressure tire. Moreover, you may form the cutting die of the ridgeline of the cutter part which provided different width | variety according to a demand. Alternatively, the die may be formed by performing etching twice or more.
