These metal sheets must maintain a high degree of flatness for subsequent joining processes, such as laser welding, and must be manufactured with little curvature, especially at the edges of the shapes. For this reason, metal sheets are currently processed by an etching process. However, the etching process itself is complex, has the disadvantage of being vulnerable to foreign matter management in the etching process, and has a high production cost.

이하에서는, 본 발명의 다양한 실시예들에 대하여, 도면을 참조하여 상세히 설명한다.Hereinafter, various embodiments of the present invention will be described in detail with reference to the drawings.
도 1은 프레스 타발 가공 공정을 위한 고속 타발 장치의 개략도이고, 도 2는 상기 프레스 타발 가공 공정으로 제조된 금속 시트의 곡률 형성을 예시하는 도면이고, 도 3은 프레스 타발 가공 공정으로 제조된 니켈 금속 시트의 사진이다. Figure 1 is a schematic diagram of a high-speed punching device for a press punching process, Figure 2 is a diagram illustrating the curvature formation of a metal sheet manufactured by the press punching process, and Figure 3 is a nickel metal manufactured by the press punching process. This is a picture of the sheet.
도 1은 프레스 타발 가공 공정에 이용되는 일반적인 고속 타발 장치의 개략도이다. 상기 고속 타발 장치는 필름이나 테이프 등에 일정한 패턴의 절단 형상을 고속으로 만들도록 제작된 것으로서, 금형 칼(15)이 부착되어 있는 상측 금형(10)과 평평한 평판의 하측 금형(20)을 포함한다. 상측 금형(10)이 하측 금형(20)이 서로 맞물리도록 상기 상측 금형이 하측 금형으로 가압되면, 상기 금형 칼이 피가공물(30)인 니켈 금속 시트지로부터 형상을 잘라 상기 니켈 금속 시트지로부터 소정의 형상, 본 실시예에서는 직사각형의 금속 시트를 형성하게 된다. 1 is a schematic diagram of a general high-speed punching device used in a press punching process. The high-speed punching device is manufactured to create a cut shape of a certain pattern such as a film or tape at high speed, and includes an upper mold 10 to which a mold knife 15 is attached and a lower mold 20 of a flat plate. When the upper mold 10 is pressed against the lower mold so that the lower mold 20 engages with each other, the mold knife cuts a shape from the nickel metal sheet, which is the workpiece 30, and forms a predetermined shape from the nickel metal sheet. , In this embodiment, a rectangular metal sheet is formed.
그러나, 이러한 종래의 고속 타발 장치를 이용하면, 금형 칼이 니켈 금속 시트지를 프레스 압력으로 소정의 형상대로 자르는 것이므로, 상기 금형 칼이 누르는 부분 근처의 금속 시트의 외주 형상 에지에서는 도 2에서 보는 바와 같은 곡률이 생기게 된다. 따라서, 금속 시트가 요구하는 곡률이 없는 고 평탄도를 달성할 수 없게 된다. 상기 프레스 타발 가공 공정으로 제조된 금속 시트의 사진을 도시하고 있는 도 3을 참조하여 보면 이를 명확히 이해할 수 있다. 이와 같이, 종래의 고속 타발 장치에 의한 프레스 타발 가공 공정으로는 요구되는 평탄도의 금속 시트를 제조하는 것이 용이하지 않다. However, when using such a conventional high-speed punching device, the mold knife cuts the nickel metal sheet into a predetermined shape with press pressure, so the outer edge of the metal sheet near the portion pressed by the mold knife has a shape as shown in FIG. 2. A curvature occurs. Therefore, it becomes impossible to achieve the high flatness without curvature required by the metal sheet. This can be clearly understood by referring to FIG. 3, which shows a photograph of a metal sheet manufactured through the press punching process. As such, it is not easy to manufacture a metal sheet with the required flatness using a press punching process using a conventional high-speed punching device.
도 4는 본 발명의 일 실시예에 따른 프레스 압착 가공 공정을 위한 고속 타발 장치의 개략도이고, 도 5는 도 4의 실시예에 따른 고속 타발 장치로 제조된 금속 시트의 사진이다.FIG. 4 is a schematic diagram of a high-speed punching device for a press compression processing process according to an embodiment of the present invention, and FIG. 5 is a photograph of a metal sheet manufactured with the high-speed punching device according to the embodiment of FIG. 4.
본 발명의 일 실시예에 따른 고속 타발 장치는 상측 금형과 하측 금형을 포함하고, 상기 상측 금형과 상기 하측 금형의 사이에 공급되는 피가공물을 압착 가공하는 고속 타발 장치로서, 상기 도 1에 도시된 종래의 고속 타발 장치는 금형 칼로 형상을 자르는 방식임에 반해, 본 실시예에 따른 고속 타발 장치는 상판에 부착된 형상 스틱으로, 하판에 형성되고, 상기 형상 스틱의 형상에 대응하는 오목 홈 내로 눌러 찍어내는 방식이라는 점에 차이가 있다. 이하, 상기 차이점이 부각될 수 있도록 본 실시예에 따른 고속 타발 장치를 설명한다.A high-speed punching device according to an embodiment of the present invention includes an upper mold and a lower mold, and is a high-speed punching device that presses and processes a workpiece supplied between the upper mold and the lower mold, as shown in FIG. 1. While the conventional high-speed punching device cuts the shape with a mold knife, the high-speed punching device according to this embodiment is a shape stick attached to the upper plate, formed on the lower plate, and pressed into a concave groove corresponding to the shape of the shape stick. The difference lies in the method of printing. Hereinafter, a high-speed punching device according to this embodiment will be described so that the differences can be highlighted.
도 4를 참조하여 보면, 상기 상측 금형은 바닥면이 소정의 형상, 본 실시예에서는 직사각형 형상으로 이루어진 형상 스틱(110)이 돌출 형성된 상부 성형판(100)과 상기 형상 스틱이 관통하는 형상 홀(120)이 구비되는 상부 지지체(120)를 포함하여 이루어진다. 상기 하측 금형은 상기 상부 성형판(100)의 상기 형상 스틱(110)과 대응되도록 상기 소정의 형상의 오목 홈(210)이 형성된 하부 성형판(200)으로 이루어져 있다. 평평한 평판으로 형성된 도 1에 도시된 고속 타발 장치의 하측 금형과는 달리 니켈 금속 시트의 형상인 직사각형 형상의 오목 홈이 형성되어 있다는 점에서 본 실시예는 그 구성적 특징이 있다. Referring to FIG. 4, the upper mold has a bottom surface of a predetermined shape, in this embodiment, a rectangular shape, an upper molding plate 100 on which a shape stick 110 is protruding, and a shape hole through which the shape stick penetrates. It includes an upper support 120 provided with 120). The lower mold consists of a lower molding plate 200 in which a concave groove 210 of the predetermined shape is formed to correspond to the shape stick 110 of the upper molding plate 100. This embodiment has a structural feature in that, unlike the lower mold of the high-speed punching device shown in FIG. 1, which is formed of a flat plate, a rectangular concave groove in the shape of a nickel metal sheet is formed.
또한, 상기 상부 성형판(110)과 상기 상부 지지체(120) 사이는 탄성 지지 부재(300)로 지지되어 있다. 본 실시예에서는 스프링으로 구현되고 있다. 상기 상측 금형이 상기 하측 금형과 서로 맞물리도록 상기 상측 금형이 상기 하측 금형으로 가압될 때, 상기 탄성 지지부재(300)의 작동으로, 먼저 상부 지지체(120)와 하부 성형판(200)이 맞물리고, 더욱 가압되면, 상기 상부 성형판(100)의 상기 형상 스틱(110)이 상기 형상 홀(130)을 관통하여 상기 오목 홈(210)내로 이동하여, 상기 피가공물을 압착하여 소정의 형상을 가공한다. In addition, the upper molding plate 110 and the upper support 120 are supported by an elastic support member 300. In this embodiment, it is implemented with spring. When the upper mold is pressed against the lower mold so that the upper mold engages with the lower mold, the upper support 120 and the lower mold plate 200 are first engaged by the operation of the elastic support member 300. When further pressed, the shape stick 110 of the upper molding plate 100 penetrates the shape hole 130 and moves into the concave groove 210 to press the workpiece to form a predetermined shape. do.
본 실시예에서, 피가공물은 캐리어 시트지에 니켈 금속 시트지가 합지된 시트지이고, 상기 상측 금형과 상기 하측 금형이 맞물리도록 가압되면, 상기 합지된 시트지가 상기 오목 홈(210)과 상기 형상 스틱(110) 사이에 압착되어 상기 소정의 형상대로 반절단된 금속 시트가 형성된다.In this embodiment, the workpiece is a sheet of nickel metal sheets laminated to a carrier sheet, and when the upper mold and the lower mold are pressed to engage, the laminated sheet forms the concave groove 210 and the shaped stick 110. ) to form a metal sheet that is cut in half into the predetermined shape.
상기 오목 홈(210)의 깊이는 상기 캐리어 시트지에 니켈 금속 시트지가 합지된 시트지인 피가공물을 눌러 찍는 정도와 관련이 있고, 최종 결과물인 금속 시트의 형상 에지에 곡률이 생기는 지에 영향을 미친다. 따라서, 상기 오목 홈(210)의 치수는 금속 시트의 치수에 의해 조정되나, 일반적으로 120㎛ 내지 180㎛, 바람직하게는 140㎛ 내지 160㎛ 이고, 더 바람직하게는 150㎛이다. 상기 오목 홈의 깊이가 상기 범위 이하이면 금속 시트의 형상이 제대로 나오지 않게 되고, 상기 범위 이상이면 베이스 필름인 캐리어 시트지가 찢어지는 현상이 발생할 수 있다. The depth of the concave groove 210 is related to the degree to which the workpiece, which is a sheet of nickel metal sheets laminated onto the carrier sheet, is pressed, and affects whether or not a curvature is created at the edge of the shape of the final resultant metal sheet. Accordingly, the size of the concave groove 210 is adjusted depending on the size of the metal sheet, but is generally 120 μm to 180 μm, preferably 140 μm to 160 μm, and more preferably 150 μm. If the depth of the concave groove is less than the above range, the shape of the metal sheet will not come out properly, and if it is more than the above range, the carrier sheet, which is the base film, may be torn.
