Description

알루미늄 플레이트의 제조 방법{Manufacturing method of aluminium plate}Manufacturing method of aluminum plate

본 발명은 알루미늄 플레이트의 제조 방법에 관한 것으로서, 특히 알루미늄 빌렛을 압출함으로써 두께를 최소화함과 아울러 압출된 소재를 압연하여 두께 균일도를 향상시키는 알루미늄 플레이트의 제조 방법에 관한 것이다.The present invention relates to a method of manufacturing an aluminum plate, and more particularly to a method of manufacturing an aluminum plate to minimize the thickness by extruding the aluminum billet and to improve the thickness uniformity by rolling the extruded material.

여러 가지 용도로 사용되고 있는 알루미늄 플레이트는 기존의 스틸 플레이트에 비해 중량이 가볍고 성형이 용이하기 때문에 최근에는 매우 다양한 분야에서 스틸 플레이트를 대체하면서 적용되고 있다.Aluminum plates, which are used for various purposes, are lighter and easier to form than conventional steel plates, and have recently been applied while replacing steel plates in a wide variety of fields.

그 대표적인 적용예로는, LCD(Liquid Crystal Display) 모듈이나 LED(Light Emitting Diode) 모듈 또는 PDP(Plasma Display Panel) 모듈과 같은 디스플레이장치의 바텀 플레이트(bottom plate)를 비롯한 새시(sash)를 들 수 있으며, 이 외에도 태양광 모듈이나 조명장치 및 각종 광원장치 등과 같은 전자/전기 장치 구성 부품들의 테두리를 고정하면서 보호하기 위한 프레임을 형성하는 새시에도 적용되고 있다.Typical applications include sash, including bottom plates of display devices such as liquid crystal display (LCD) modules, light emitting diode (LED) modules, or plasma display panel (PDP) modules. In addition, it is applied to a chassis forming a frame for protecting and fixing the edges of electronic / electrical device components such as solar modules, lighting devices, and various light source devices.

한편, 알루미늄 플레이트의 소재로는 1100, 3003, 5052, 5083, 5086 등의 비열처리 합금계열과 6061, 6063 등의 열처리 합금계열이 있다. 그리고, 통상적인 알루미늄 플레이트는, 예를 들어 3003이나 5052계의 알루미늄 주조 슬라브를 압연 공정을 통해 제조하게 된다.On the other hand, the material of the aluminum plate is a non-heat treatment alloy series such as 1100, 3003, 5052, 5083, 5086 and heat treatment alloy series such as 6061, 6063. In addition, a typical aluminum plate, for example, is to produce a cast aluminum slab of 3003 or 5052 system through a rolling process.

압연 공정에 의해 알루미늄 플레이트를 제조하는 근본적인 이유는, 압출을 하고자 할 경우 제조 가능한 폭 및 두께의 제한으로 인해 원하는 사이즈의 알루미늄 플레이트를 제조할 수 없기 때문이다. 따라서, 지금까지의 압연 방법으로는 최근에 두께가 얇고 폭이 넓은 디스플레이 장치 등의 요구 사양에 적합한 알루미늄 플레이트를 제조하기는 사실상 불가능하다고 할 수 있다. 더욱이, 압연 공정에 의한 알루미늄 플레이트의 제조는 플레이트의 형상에 제한이 따르므로 후속가공이 요구된다는 문제가 있다.The fundamental reason for producing the aluminum plate by the rolling process is that it is not possible to produce an aluminum plate of the desired size due to the limitation of the width and thickness that can be produced when the extrusion is desired. Therefore, it can be said that it is virtually impossible to manufacture the aluminum plate suitable for the requirements of a thin thickness and wide display apparatus etc. by the rolling method until now. Moreover, there is a problem that the manufacture of the aluminum plate by the rolling process requires a subsequent processing because of limitations on the shape of the plate.

이에, 기존의 압연 공정이 아닌 압출 공정에 의해 최근에 요구되고 있는 광폭의 얇은 디스플레이 장치 등에 적용 가능한 폭과 두께를 갖는 알루미늄 플레이트의 제조 방법이 필요한 실정이다.Accordingly, there is a need for a method of manufacturing an aluminum plate having a width and a thickness applicable to a wide thin display device that is recently required by an extrusion process rather than a conventional rolling process.

본 발명은 전술한 바와 같은 종래의 문제점을 감안함과 아울러 알루미늄 플레이트에 대한 새로운 제조 방법을 적용하기 위해 개발된 것으로서, 그 목적은 기존의 압연 공정을 대체하면서 수요가의 요구에 부응하여 폭과 두께의 치수 제한을 극복할 수 있는 알루미늄 플레이트의 제조 방법을 제공하는 데에 있다.The present invention has been developed to apply the new manufacturing method for aluminum plate in addition to the conventional problems as described above, the object of which is to replace the existing rolling process in response to the demand of the demand of the width and thickness An object of the present invention is to provide a method of manufacturing an aluminum plate capable of overcoming the dimensional limitation of the present invention.

위와 같은 목적을 달성하기 위한 본 발명은, 알루미늄 빌렛을 소정의 폭과 두께를 갖는 알루미늄 플레이트로 소성가공하는 알루미늄 플레이트의 제조 방법에 있어서, 상기 알루미늄 빌렛이 압입되는 입구로부터 압출되는 출구까지의 치수가 계단식으로 감소하면서 상기 알루미늄 플레이트의 두께에 상응하는 치수로 되는 압출 호울이 형성된 압출 다이를 통해 상기 알루미늄 빌렛을 압출하여 알루미늄 플레이트로 가공하는 압출 과정을 포함하여 이루어진 알루미늄 플레이트의 제조 방법을 제공한다.In the present invention for achieving the above object, in the manufacturing method of the aluminum plate for plastic processing the aluminum billet into an aluminum plate having a predetermined width and thickness, the dimension from the inlet to the outlet to which the aluminum billet is press-fitted It provides a method for producing an aluminum plate comprising the extrusion process of extruding the aluminum billet through an extrusion die formed with an extrusion hole having a dimension corresponding to the thickness of the aluminum plate while decreasing stepwise.

상기 방법에 있어서, 상기 압출 과정 직후에 알루미늄 플레이트의 두께 균일도 향상을 위해 알루미늄 플레이트를 압연하는 압연 과정이 수행이 될 수 있다.In the above method, immediately after the extrusion process, a rolling process of rolling the aluminum plate may be performed to improve thickness uniformity of the aluminum plate.

상기와 같이 구성된 본 발명에 따르면, 기존의 압연 공정을 대체하면서 수요 가의 요구에 부응하여 폭과 두께의 치수 제한을 극복할 수 있는 알루미늄 플레이트의 제조 방법을 제공함으로써, 기존의 압연 공정이 아닌 압출 공정에 의해 최근에 요구되고 있는 광폭의 얇은 디스플레이 장치 등에 적용 가능한 폭과 두께를 갖는 알루미늄 플레이트를 제조할 수 있게 된다.According to the present invention configured as described above, by providing a manufacturing method of the aluminum plate that can overcome the limitation of the width and thickness in response to the demand of the demand while replacing the existing rolling process, extrusion process rather than the conventional rolling process This makes it possible to manufacture an aluminum plate having a width and a thickness applicable to a wide thin display device and the like which have recently been required.

또한, 본 발명에 따르면, 기존의 압출 과정에서 사용되던 압출 장비에 비해 압출에 필요한 압력이 저감되고, 제조되는 알루미늄 플레이트의 두께 변화가 최소화되며, 압출 다이의 수명도 향상될 뿐만 아니라, 제조하고자 하는 알루미늄 플레이트의 사이즈에 대한 재현성을 확보할 수 있어, 비용을 절감하면서 품질이 양호한 알루미늄 플레이트를 제조할 수가 있다.In addition, according to the present invention, compared to the extrusion equipment used in the existing extrusion process, the pressure required for extrusion is reduced, the thickness change of the aluminum plate to be produced is minimized, and the life of the extrusion die is also improved, The reproducibility with respect to the size of an aluminum plate can be ensured, and the aluminum plate of favorable quality can be manufactured, reducing cost.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다. 그러나, 이하의 실시예는 이 기술분야에서 통상의 지식을 가진 자에게 본 발명이 충분히 이해되도록 제공되는 것으로서 여러 가지 다른 형태로 변형될 수 있으며, 본 발명의 범위가 다음에 기술되는 실시예에 한정되는 것은 아니다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It doesn't happen.

도 1은 본 발명에 따른 알루미늄 플레이트의 제조 방법에 대한 바람직한 실시예로서의 공정도이다.1 is a process chart as a preferred embodiment of the manufacturing method of the aluminum plate according to the present invention.

도 1의 공정도에 예시된 바와 같이, 본 발명에 따른 알루미늄 플레이트의 제조 방법은, 알루미늄 빌렛(B)을 압출 다이(1)를 통해 압출함으로써 소정의 폭과 두 께를 갖는 알루미늄 플레이트(P)로 소성가공하는 압출 과정을 특징적인 공정으로 하고 있다.As illustrated in the process diagram of FIG. 1, the manufacturing method of the aluminum plate according to the present invention is to extrude an aluminum billet B through an extrusion die 1 to an aluminum plate P having a predetermined width and thickness. The extrusion process of plastic working is a characteristic process.

본 발명에서 제조하고자 하는 알루미늄 플레이트의 소재로는 6061, 6063 등의 열처리 합금계열뿐만 아니라 1100, 3003, 5052, 5083, 5086 등의 비열처리 합금계열에 한정되지 아니한다. 그리고, 본 발명에 따라 제조된 알루미늄 플레이트는 LCD 모듈이나 LED 모듈 또는 PDP 모듈과 같은 디스플레이장치의 바텀 플레이트(bottom plate)를 비롯한 새시에 적용될 수 있으며, 이 외에도 태양광 모듈이나 조명장치 및 각종 광원장치 등과 같은 전자/전기 장치 구성 부품들의 테두리를 고정하면서 보호하기 위한 프레임을 형성하는 새시에도 적용될 수 있다.The material of the aluminum plate to be manufactured in the present invention is not limited to not only heat-treated alloys such as 6061 and 6063, but also non-heat-treated alloys such as 1100, 3003, 5052, 5083, and 5086. In addition, the aluminum plate manufactured according to the present invention may be applied to a chassis including a bottom plate of a display device such as an LCD module, an LED module, or a PDP module. In addition, a solar module, an illumination device, and various light source devices It may also be applied to a chassis that forms a frame for protecting and securing the edges of electronic / electrical device components such as the like.

본 발명의 압출 과정에서 적용되는 압출 장비는, 도 2(a)에 도시된 것과 같이, 압출 소재인 알루미늄 빌렛(B)이 수용되는 컨테이너(2)와, 이 컨테이너(2)에 수용된 알루미늄 빌렛(B)의 단면이 수축하면서 원하는 폭과 두께로 소성되도록 하기 위한 압출 다이(1), 그리고 컨테이너(2)에 수용된 알루미늄 빌렛(B)을 압출 다이(1) 쪽으로 밀어내는 더미 블록(3)과 램(4)으로 구성되어 있다. 특히, 상기 압출 다이(1)는 알루미늄 빌렛(B)이 압입되는 입구(1a)로부터 압출되는 출구(1b)까지의 치수가 계단식으로 감소하면서 제조하고자 하는 알루미늄 플레이트의 두께에 상응하는 치수로 되는 압출 호울(1c)을 구비하고 있다.Extrusion equipment applied in the extrusion process of the present invention, as shown in Fig. 2 (a), the container 2 is accommodated in the aluminum billet (B) as the extrusion material, and the aluminum billet accommodated in the container ( Extrusion die 1 for causing the cross-section of B) to be fired to a desired width and thickness, and a dummy block 3 and a ram for pushing the aluminum billet B contained in the container 2 toward the extrusion die 1. It consists of (4). In particular, the extrusion die 1 is extruded to a dimension corresponding to the thickness of the aluminum plate to be manufactured while the dimension from the inlet 1a into which the aluminum billet B is pressed into the outlet 1b to be extruded decreases stepwise. The hole 1c is provided.

이러한 본 발명의 압출 다이(1)와 비교하여, 도 2(b)에 도시된 기존의 압출 다이(10)를 참조해보면, 기존의 압출 다이(10)에 구비된 압출 호울(10c)은 알루미늄 빌렛(B)이 압입되는 입구(10a)로부터 압출되는 출구(10b)까지의 치수가 동일한 구조로 되어 있음을 알 수 있다. Compared to the extrusion die 1 of the present invention, referring to the conventional extrusion die 10 shown in Figure 2 (b), the extrusion hole 10c provided in the conventional extrusion die 10 is an aluminum billet It can be seen that the dimension from the inlet 10a into which (B) is press-fitted to the outlet 10b extruded is the same structure.

따라서, 본 발명의 압출 다이(1)를 적용하여 알루미늄 빌렛(B)을 압출하면, 컨테이너(2)에 수용된 알루미늄 빌렛(B)이 램(4)에 의해 밀려서 압출 다이(1)의 압출 호울(1c)로 압출될 때, 계단식으로 치수가 감소하는 압출 호울(1c)의 각 단계를 거칠 때마다 압력이 저감되는데, 본 발명의 발명자가 실험한 결과에 따르면 치수가 동일한 압출 호울(10c)을 구비한 기존의 압출 다이(1)를 적용하였을 경우와 대비하였을 때 약 15%씩 압출에 필요한 압력이 저감되는 것으로 나타났다.Therefore, when the aluminum billet B is extruded by applying the extrusion die 1 of the present invention, the aluminum billet B accommodated in the container 2 is pushed by the ram 4 so that the extrusion hole 1 of the extrusion die 1 When extruded to 1c), the pressure decreases with each step of the extrusion hole 1c which decreases in size stepwise. According to the results of the experiments of the present invention, the extrusion hole 10c having the same dimensions is provided. The pressure required for extrusion was reduced by about 15% compared with the case of applying the conventional extrusion die 1.

또한, 본 발명의 압출 다이(1)를 적용하는 경우, 압출되는 소재가 압출 호울(1c)을 통해 단계적으로 압출되므로 제조되는 알루미늄 플레이트의 두께 변화가 최소화되며, 압출 다이(1)의 수명도 종래의 압출 다이(10)에 비해 40% 이상 향상될 뿐만 아니라, 제조하고자 하는 알루미늄 플레이트의 폭과 두께를 연속적으로 유지하여 재현성을 확보할 수가 있다.In addition, in the case of applying the extrusion die 1 of the present invention, since the extruded material is extruded stepwise through the extrusion hole (1c), the change in the thickness of the aluminum plate to be produced is minimized, and the life of the extrusion die 1 is also conventional In addition to the 40% or more improvement over the extrusion die 10, the reproducibility can be ensured by continuously maintaining the width and thickness of the aluminum plate to be manufactured.

참고로, 본 발명에 따른 압출 과정에 대한 작업예를 들면 다음과 같다. 길이 780mm의 6063계 알루미늄 빌렛(B)을 알루미늄 플레이트(P)로 압출하기 위해 알루미늄 빌렛(B)을 560℃로 가열하여 압출 장비로 투입하였다. 이때, 컨테이너(2)의 온도를 460℃, 압출 다이(1)의 온도를 491℃로 하였으며, 램(4)의 속도를 1.4mm/sec로 하면서 압출되는 출구(1b)의 온도를 450℃로 하여 압출 작업을 수행한 결과, 굴곡이나 막힘이 없이 알루미늄 플레이트를 양산할 수 있었다. 특히 8,000톤급 압출 장비를 적용할 경우, 알루미늄 빌렛(B)을 폭 650mm의 알루미늄 플레이트(P)로 압출할 수 있었으며, 알루미늄 플레이트(P)의 두께는 기존에 4mm까지 압연 공정을 통해 생산할 수 있었으나, 본 발명에서는 압출 과정을 통해 1.2mm까지 생산할 수 있었다.For reference, working examples for the extrusion process according to the present invention are as follows. In order to extrude a 6063 series aluminum billet (B) having a length of 780 mm into the aluminum plate (P), the aluminum billet (B) was heated to 560 ° C. and introduced into an extrusion equipment. At this time, the temperature of the container 2 was 460 ° C, the temperature of the extrusion die 1 was 491 ° C, and the temperature of the outlet 1b to be extruded was 450 ° C while the speed of the ram 4 was 1.4mm / sec. As a result of the extrusion operation, it was possible to mass-produce the aluminum plate without bending or clogging. In particular, when the 8,000-ton extrusion equipment was applied, the aluminum billet (B) could be extruded into an aluminum plate (P) having a width of 650 mm, and the thickness of the aluminum plate (P) could be produced through a rolling process up to 4 mm, In the present invention, it could be produced up to 1.2mm through the extrusion process.

한편, 상기와 같은 압출 과정을 통해 알루미늄 플레이트(P)로 소성가공된 소재에 대해 두께 균일도를 향상시킬 목적으로 후속 공정이 더 수행될 수 있다. 즉, 도 1에 예시된 것처럼, 상기 압출 장비의 선단에 압연 롤(5)을 배치함으로써 압출 과정 직후에 압연 과정을 수행할 수 있다. 이와 같이 압출 과정과 압연 과정이 함께 수행됨에 따라, 본 발명에서는 두께가 얇으면서도 균일한 고품질의 알루미늄 플레이트(P)를 제조할 수 있게 된다.On the other hand, the following process may be further performed for the purpose of improving the thickness uniformity for the plastic processed into the aluminum plate (P) through the extrusion process as described above. That is, as illustrated in FIG. 1, the rolling process may be performed immediately after the extrusion process by placing the rolling roll 5 at the tip of the extrusion equipment. As described above, as the extrusion process and the rolling process are performed together, in the present invention, a thin and uniform high quality aluminum plate P can be manufactured.

이상에서는 본 발명을 바람직한 실시예에 의거하여 설명하였으나, 본 발명은 상기 실시예에 한정되는 것은 아니며, 본 발명의 기술적 사상의 범위 내에서 이 기술분야에서 통상의 지식을 가진 자에 의하여 여러 가지 변형이 가능하다.In the above described the present invention based on the preferred embodiment, the present invention is not limited to the above embodiment, various modifications by those skilled in the art within the scope of the technical idea of the present invention This is possible.
