Abstract

A manufacturing method of a compound wire by extrusion uses 5056 Al alloy with good toughness and corrosion reistance as core material and 6253 Al alloy with good formability and corrosion resistance as skinning material. A billet composed of above two materials is used and the cross sectional area of the skinning material should be above 16%. A compound wire of about 15mm diameter is made by hot extrusion at 300≰C and a drawing of this wire gives the compound wire of a designed diameter. A compound wire manufactured by this process has good toughness and corrosion resistance.

Description

압출에 의한 복합 선재의 제조방법Method for manufacturing composite wire rod by extrusion

첨부된 도면은 본 발명의 압출상태를 예시한 도면임.The accompanying drawings are views illustrating the extrusion state of the present invention.

본 발명은 알미늄 합금으로 세선을 제조하는 방법에 관한 것으로, 좀더 상세하게는 심재로서는 강인성과 내식성을 가진 알미늄 합금 5056으로 하고, 외피재는 가공성과 내식성을 가진 알미늄 합금 6253으로 하여 이를 복합선재로 만드는 방법에 관한 것이다.The present invention relates to a method for producing fine wires with an aluminum alloy, and more specifically, as a core material, an aluminum alloy 5056 having toughness and corrosion resistance, and an outer shell material of an aluminum alloy 6253 having workability and corrosion resistance, thereby making it a composite wire. It is about.

종래의 정수압 압출에 의하여 선재, 봉재등을 제조하여 왔으나, 그러나 이러한 방법은 심재와 외층재의 변형저항을 일치시키기는 데에 매우 어렵게 되기 때문에 만족스러운 제품을 얻을 수가 없는 것이었다.Wire rods, rods and the like have been manufactured by conventional hydrostatic extrusion, but this method has been difficult to match the deformation resistance of the core material and the outer layer material, so that a satisfactory product cannot be obtained.

따라서, 상기와 같은 심재와 외층재의 변형저향을 일치시키기 위하여 심재와 외층재 사이에 표면처리를 시행하여 양 재료 사이에 압출시에 밀착을 증진시키고, 또한, 압출을 개시할 때에 미리 선단부를 압출 성형된 제품의 직경과 동일하게 형성시켜서 이를 압출시에 제품을 균일하게 유도시키는 역할을 행하도록 된 것도 제안된 바 있으나, 이러한 방법은 고압의 유체에 의하여 실온에서 압출을 행하기 때문에 그 압출압이 대단히 높게 되어서 이를 실요화 시키는 데에는 여러가지 문제점이 있을 뿐만 아니라, 시설이 대규모로 되어 시설비가 고가로 되는 문제점이 있는 것이 있다.Therefore, in order to match the deformation propensity of the core material and the outer layer material, surface treatment is performed between the core material and the outer layer material to improve the adhesion at the time of extrusion between the two materials, and also extrude the tip part before starting the extrusion. It has been proposed to form the same as the diameter of the finished product to play a role of uniformly inducing the product during extrusion, but this method extrudes at room temperature by high pressure fluid, so the extrusion pressure is very high. There is a problem that not only has various problems in realizing this, but also the facility is expensive due to the large scale of the facility.

따라서, 분 발명의 목적은 복합빌렛을 열간압출과 드로잉의 두가지 방법을 이용하여 예컨대, 방충망의 제조용 선재로 사용할 수 있는 정도의 세선을 제조하는 방법을 제공하는 데에 있는 것이다.Accordingly, an object of the present invention is to provide a method for producing a thin wire to the extent that the composite billet can be used as a wire for the production of an insect screen, for example, by using two methods of hot extrusion and drawing.

즉, 본 발명의 복합선재의 제조방법은 압출방법으로 복합선재를 제조하는 방법에 있어서, 강인성과 내식성이 우수한 알미늄 5056을 심재로 하고, 가공성과 내식성이 우수한 알미늄 6253을 외피재로 하여 이를 복합빌렛으로 하되, 외피재의 단면적을 전체 단면적의 16%이상으로 하고, 이를 대략 300℃에서 열간압출을 행하여 직경이 15mm정도의 선재를 만든 후에 이를 드로잉작업을 행하여 알미늄 복합 선재를 제조하는 방법인 것이다.That is, in the method of manufacturing the composite wire of the present invention, in the method of manufacturing the composite wire by the extrusion method, aluminum 5056 having excellent toughness and corrosion resistance is used as the core material, and aluminum 6253 having excellent workability and corrosion resistance is used as the composite billet. However, the cross-sectional area of the outer shell material is 16% or more of the total cross-sectional area, and hot extrusion is performed at approximately 300 ° C. to produce a wire rod having a diameter of about 15 mm, and then drawing is performed to manufacture the aluminum composite wire.

이를 좀더 상세히 공정별로 설명하면 다음과 같다.This will be described in more detail by process as follows.

우선, 강인성과 내식성이 강한 알미늄 5056을 심재(1)로 하고, 가공성과 내식성이 강한 알미늄 합금 6253을 파이프상의 외피재(2)로 하여 관삽이나, 또는 복합주조에 의하여 복합빌렛(3)을 만들되, 외피재(2)가 차지하는 단면적을 전체단면의 16%이상으로 한다.First, a composite billet (3) is made by pipe insertion or composite casting using aluminum 5056 having high toughness and corrosion resistance as the core material (1) and aluminum alloy 6253 having high workability and corrosion resistance as the outer shell material (2). The cross-sectional area occupied by the shell material 2 is to be at least 16% of the total cross section.

이는 본 발명의 방법을 수회에 거쳐서 실험을 행한 결과, 상기한 16%이하일 때에는 외피재(2)가 심재에 균일하게 피복된 상태를 얻을 수 없고, 외피재(2)가 피복이 안된 부분이 간헐적으로 발생되어 최소한 16%이상으로 되어야 하는 것을 알아내게 된 것이다.As a result of conducting the experiment of the method of the present invention several times, when the above 16% or less, it is not possible to obtain a state in which the outer cover material 2 is uniformly coated on the core material, and the part where the outer cover material 2 is not coated is intermittent. Was found to be at least 16%.

다음에, 상기한 복합빌렛(3)을 300℃로 가열된 상태하에서 압축기(5)에서 압출하여 직경이 15mm정도의 선재(4)를 만든다. 이어서, 이 15mm정도의 선재(4)를 최종제품의 선경에 따라서 드로잉작업을 수회에 거쳐서 행한 다음에 최종제품인 알미늄 복합선재를 얻는 방법인 것이다.Next, the composite billet 3 is extruded from the compressor 5 while heated to 300 ° C. to form a wire 4 having a diameter of about 15 mm. Subsequently, the wire rod 4 of about 15 mm is drawn several times in accordance with the wire diameter of the final product, and then the aluminum composite wire which is the final product is obtained.

따라서, 본 발명의 제조방법에 의하여 제조되는 알미늄 합금의 복합선재는 그 시설이 간단하게 되어 시설비가 적게 드는 이점이 있으며, 또한, 작업하는 데에 숙련이 필요하지 않게 되어 작업인원의 선정의 폭이 넓어 인건비의 절감을 가져오며, 본 발명의 제조방법에 의하여 제조된 제품은 알미늄 합금 5056으로 심재로 하였기 때문에 완제품에 내식성과 강인성을 부여하게 되고, 또한 알미늄 합금 6253을 외피재로 사용한 것이어서 내식성이 뛰어나서 주로 방충망 제조용의 복합선재로 사용하기에 가장 적합한 복합선재를 얻을 수 있게 되는 것이다.Therefore, the composite wire of the aluminum alloy produced by the manufacturing method of the present invention has the advantage that the facility is simple, and the cost of the facility is low, and also the skilled person is not required to work, so the width of the selection of the working personnel is increased. Wider labor costs, and the product produced by the manufacturing method of the present invention is made of aluminum alloy 5056 core material to give corrosion resistance and toughness to the finished product, and also used aluminum alloy 6253 as an outer shell material, so excellent corrosion resistance It is possible to obtain a composite wire that is most suitable for use as a composite wire mainly for insect screen manufacturing.
