이상에서 살펴본 바와 같이, 본 발명에 의하면, 알루미늄 보다 가벼우면서 경도가 높다. 또, 알루미늄 보다 내충격성이 좋다. 현존하는 금속중 전자파 차단 효과(EMI)가 매우 높다. 특히, 기존 판재의 가공이 어려운 점(깨지는 현상)을 해결하고, 표면경도를 향상시킨다. 또, 마그네슘 표면의 산화가 쉽게 되는 것을 방지하고, 재질의 금속감을 살리면서 표면에 샌딩면과 유광면을 동시에 나타낼 수 있다. 또, 본 발명은 종래의 다이캐스팅 제품에 비하여 두께를 얇게 할 수 있고, 뒷면에 용접을 하여 조립을 용이하게 할 수 있는 유용한 발명이다. As discussed above, according to the present invention, the hardness is higher than that of aluminum. Moreover, impact resistance is better than aluminum. Among the existing metals, the electromagnetic shielding effect (EMI) is very high. In particular, it solves the difficult point (breaking phenomenon) of the existing sheet material and improves the surface hardness. In addition, the oxidation of the magnesium surface can be prevented from being easily performed, and the sanding surface and the glossy surface can be simultaneously displayed on the surface while utilizing the metallic texture of the material. In addition, the present invention is a useful invention that can be thinner than the conventional die-casting products, and can be easily assembled by welding the back side.

이하, 본 발명의 실시예를 설명한다. 도 1은 본 발명에서 사용되는 마그네슘합금의 판재 금형장치의 사시도이다. 도 1에 의하면, 마그네슘합금의 판재 금형장치는 하층에 위치한 다이홀더(1)와, 상층에 위한 펀치홀더(2), 다이홀더(1)와 펀치홀더(2)를 결합하는 4개의 지지봉(3)을 포함한다. 또, 금형장치를 개폐하는 조작용 핸들(4)과, 다이홀더(1)와 펀치홀더(2) 사이에 다음과 같은 부품들이 적층되어 결합된다. 본 발명의 목적물(대상물)인 판재(6)를 제조하기 위한 금형장치의 부품은 하층(아래층)에서부터 하층 열처리용 비석면판(10)과, 하층 열차단용 비석면판(12)과, 하층 티타늄판(13)과, 하층 히터(16)와, 하층 금형(15)이 순서대로 적층되어 결합된다.Hereinafter, embodiments of the present invention will be described. 1 is a perspective view of a sheet metal mold apparatus of magnesium alloy used in the present invention. According to Figure 1, the sheet metal mold apparatus of magnesium alloy has a die holder (1) located in the lower layer, four support rods (3) for coupling the punch holder (2), die holder (1) and punch holder (2) for the upper layer ). In addition, the following parts are laminated and coupled between the operating handle 4 for opening and closing the mold apparatus and the die holder 1 and the punch holder 2. Parts of the mold apparatus for manufacturing the plate material 6, which is the object (object) of the present invention, from the lower layer (lower layer) to the non-asbestos plate 10 for lower heat treatment, the non-asbestos plate 12 for lower heat shielding, and the lower layer titanium plate ( 13), the lower layer heater 16, and the lower layer mold 15 are laminated and bonded in order.

본 발명의 금형장치는 판재(6)를 제조하기 위한 금형장치는 마그네슘 합금의 특성이 파손되기 쉽기 때문에 이를 보완하기 위해서, 마그네슘 판재(6)를 미리서 300℃로 예열을 하는 것이 바람직하다. In the mold apparatus of the present invention, the mold apparatus for manufacturing the plate 6 is easy to break the characteristics of the magnesium alloy, to compensate for this, it is preferable to preheat the magnesium plate 6 in advance to 300 ℃.

상기 예열된 마그네슘 판재(6)를 다시 상층 금형과 하층 금형에 장착하고, 상층 히터와 하층 히터로 각각 상층 금형과 하층 금형을 280 ℃ 내지 300℃ 온도의 범위로 가열하여 일정한 온도가 되도록 한 상태에서 금형을 하는 것이 특징이다. The preheated magnesium plate 6 is mounted on the upper mold and the lower mold again, and the upper mold and the lower mold are heated to a constant temperature by heating the upper mold and the lower mold in the range of 280 ° C. to 300 ° C., respectively. It is characterized by making a mold.

본 발명의 마그네슘 판재의 표면처리 방법에 대한 실시예들을 설명한다. 기본적인 기술은 프레스가공 단계, 바렐연마 단계, 치환도금 단계, 동도금 단계를 포함한다. Embodiments of the surface treatment method of the magnesium sheet of the present invention will be described. The basic technique includes a press working step, a barrel polishing step, a substitution plating step, and a copper plating step.

제1실시예는 프레스가공 단계, 레이저 마그네슘 용접 단계, 바렐연마 단계, 치환도금 단계, 동도금 단계, 광택 연마 단계, 유광니켈도금 단계, 차폐샌딩(헤어 라인 가공) 단계, 레이저마킹 단계, 3가 크롬도금 단계 및 인쇄 단계로 구성된다. The first embodiment is a press working step, laser magnesium welding step, barrel polishing step, substitution plating step, copper plating step, polish polishing step, polished nickel plating step, shielding sanding (hair line processing) step, laser marking step, trivalent chromium It consists of a plating step and a printing step.

프레스가공 단계는 도 1과 같이, 마그네슘 판재를 금형으로 제작하는 과정을 말한다. 바렐연마는 마그네슘 판재를 압연시 판재 표면에 삽입되어 있는 슬러지를 제거하여, 도금시 이 슬러지가 박리되어 발생하는 불량을 미연에 방지하며 1차 프레스가공 단계에서 발생하는 burr를 제거함에 있다.The press working step refers to a process of manufacturing a magnesium sheet into a mold as shown in FIG. 1. Barrel polishing removes the sludge inserted into the plate surface when rolling magnesium plate, prevents the defect caused by the sludge peeling during plating and removes the burr generated in the first press processing step.

또, 치환도금은 마그네슘이 산성 도금 약품에 매우 취약하여 도금을 할 수 없으므로 먼저 마그네슘 표면에 보호막을 입히고 그 위에 도금을 하는 방법이다. 플라스틱에 도금을 할 경우 표면에 전도성 물질을 코팅하고 도금하는 방법과 동일하다. 차폐샌딩은 부분샌딩을 말하며 현재는 전체를 샌딩 또는 유광 중 한가지를 택하여야 한다. 유광면을 필요 부분만 차폐하고 샌딩하여 한가지 제품에 샌딩과 유광, 2가지 효과를 낸다.In addition, substitution plating is a method of applying a protective film on the surface of magnesium first and plating on it because magnesium cannot be plated because it is very vulnerable to acidic plating chemicals. Plating on plastics is the same as coating and plating conductive materials on the surface. Shielding sanding refers to partial sanding, and at present it should be either sanded or polished in its entirety. By shielding and sanding the surface of the gloss, only one part has two effects, sanding and gloss.

본 발명의 실시예에서 3가 크롬도금은 모두 코발트(Co)합금도금으로 대체할 수 있다.In the embodiment of the present invention, all of the trivalent chromium plating may be replaced by cobalt (Co) alloy plating.

제2실시예는 프레스가공 단계, 레이저 마그네슘 용접 단계, 바렐연마 단계, 치환도금 단계, 동도금 단계, 니켈도금 단계, 광택연마 단계, Ni 박도금 단계, 레이저 마킹 단계 , 3가 크롬 도금단계 및 인쇄단계로 구성된다. 프레스가공 단계는 도 1과 같이, 마그네슘 판재를 금형으로 제작하는 과정을 말한다. The second embodiment is the press working step, laser magnesium welding step, barrel polishing step, substitution plating step, copper plating step, nickel plating step, polish polishing step, Ni thin plating step, laser marking step, trivalent chromium plating step and printing step It consists of. The press working step refers to a process of manufacturing a magnesium sheet into a mold as shown in FIG. 1.

The third embodiment is a press working step, laser magnesium welding step, barrel polishing step, substitution plating step, copper plating step, photosensitive agent coating step, photographing step, corrosion step, Ni foil plating step, trivalent chromium plating [cobalt (Co) alloy Plating] step and printing step. The press working step refers to a process of manufacturing a magnesium sheet into a mold as shown in FIG. 1.

니켈 박도금(Ni 박도금)은 현재 일반적으로 사용하는 도금기술로, 니켈도금시 무레벨링 광택제를 사용하여 표면의 상태를 그대로 나타나게 도금하는 기술이다. 종래의 광택 닉켈도금 으로는 표면이 샌딩면과 유광면이 공존하는 제품을 도금하면, 샌딩면이 함몰되는 현상이 발생하는것을 개선하는 도금이다. 닉켈 박도금으로 도금하면, 유광면은 더욱 광이 나고 샌딩면 또한 함몰되지 아니하고, 그대로 나타난다. Nickel thin plating (Ni thin plating) is a plating technique currently used in general, and is a technique of plating the surface state as it is using nickel-free leveling varnish during nickel plating. Conventional polished nickel plating is a plating that improves the phenomenon that the sanding surface is depressed when the surface is plated with the sanding surface and the glossy surface coexist. When plated with Nickel thin plating, the polished surface is more shiny and the sanding surface is not depressed, but appears as it is.

제4실시예는 프레스가공 단계, 레이저 마그네슘 용접 단계, 바렐연마 단계, 치환도금 단계, 동도금 단계, 유광Ni도금 단계, 감광제 도포 단계, 촬영단계, 부식단계, 3가 크롬도금 단계, 코발트(Co)합금도금 단계 및 인쇄단계로 구성된다. 프레스가공 단계는 도 1과 같이, 마그네슘 판재를 금형으로 제작하는 과정을 말한다. The fourth embodiment is a press working step, laser magnesium welding step, barrel polishing step, substitution plating step, copper plating step, polished Ni plating step, photosensitive agent coating step, photographing step, corrosion step, trivalent chromium plating step, cobalt (Co) It consists of an alloy plating step and a printing step.
