Description

총열 덮개의 제조 방법{Manufacturing method of barrel cover}Manufacturing method of barrel cover}

본 발명은 총열 덮개의 제조 방법에 관한 것으로, 보다 상세하게는 알루미늄 합금 6061 소재를 인발함으로써 제조된 총열 덮개가 알루미늄 합금 7075 소재를 단조함으로써 제조된 총기의 여타 부품과 동일한 색상이 나타날 수 있도록 한 총열 덮개의 제조 방법에 관한 것이다.The present invention relates to a method of manufacturing a gun barrel cover, and more specifically, to a barrel in which a gun barrel cover manufactured by drawing aluminum alloy 6061 material can appear the same color as other parts of a firearm manufactured by forging aluminum alloy 7075 material. It relates to a method of manufacturing a cover.

일반적으로, 총기(銃器)라 함은 권총, 소총 등과 같이 화약의 폭발력에 의하여 발사물(총알)을 발사하는 무기이다.In general, a firearm is a weapon that fires projectiles (bullets) using the explosive power of gunpowder, such as a pistol or rifle.

이러한, 총기는 총알이 발사되는 총열과, 총열과 결합되는 총몸과, 총열을 감싸는 총열 덮개 등의 부품으로 구성된다.A firearm is composed of parts such as a barrel through which a bullet is fired, a gun body coupled with the barrel, and a barrel cover that surrounds the barrel.

이와 같은, 총열과, 총몸, 총열 덮개는 알루미늄 합금계 중에서도 높은 강도를 갖는 알루미늄 합금 7075 소재(Al-Zn-Mg 계)를 단조함으로써 제조된다.Such a gun barrel, gun body, and gun barrel cover are manufactured by forging aluminum alloy 7075 material (Al-Zn-Mg series), which has the highest strength among aluminum alloy series.

여기서, 알루미늄 합금 7075 소재는 높은 원가를 가지면서 추가 가공비도 비싸다는 단점이 있다.Here, the aluminum alloy 7075 material has the disadvantage of having a high cost and additional processing costs.

이에, 알루미늄 합금 6061 소재(Al-Mg-Si 계)를 인발함으로써 원가와 가공비를 낮출 수 있도록 하고자 한다.Accordingly, the goal is to reduce the cost and processing costs by drawing aluminum alloy 6061 material (Al-Mg-Si series).

그러나, 알루미늄 합금 7075 소재는 Al-Zn-Mg 계 알루미늄 합금이며, 알루미늄 합금 6061 소재는 Al-Mg-Si 계 알루미늄 합금이므로, 이 둘의 색상은 상이하게 나타나게 된다.However, since the aluminum alloy 7075 material is an Al-Zn-Mg based aluminum alloy and the aluminum alloy 6061 material is an Al-Mg-Si based aluminum alloy, the colors of the two appear different.

즉, 알루미늄 합금 7075 소재로 제조된 제품과 알루미늄 합금 6061 소재로 제조된 제품은 동일한 색상의 염료를 착색시켰을 경우 서로 다른 색상이 나타나며, 이는 구매자에게 있어 구매 욕구의 저하를 일으키는 단점이 있었던 것이다.In other words, products manufactured with aluminum alloy 7075 material and products manufactured with aluminum alloy 6061 material appear in different colors when dyed with the same color dye, which has the disadvantage of reducing purchase desire among buyers.

이하 본 발명에 의한 총열 덮개의 제조 방법에 대한 바람직한 실시예를 도면을 참조하여 설명한다. Hereinafter, a preferred embodiment of the method for manufacturing a gun barrel cover according to the present invention will be described with reference to the drawings.

도 1에는 도시된 바와 같이, 본 발명에 의한 총열 덮개의 제조 방법의 바람직한 실시예의 구성을 보인 흐름도가 도시되어 있다.As shown in Figure 1, a flow chart showing the configuration of a preferred embodiment of the method for manufacturing a gun barrel cover according to the present invention is shown.

도 1에서 도시된 바와 같이, 본 발명에 의한 총열 덮개의 제조 방법은, 알루미늄 합금 6061 소재를 인발함으로써 총열 덮개(100)를 제조하는 총열 덮개 제조 단계(S10)와, 상기 총열 덮개(100)의 표면에 산화알루미늄 피막을 형성하는 양극 산화 처리 단계(S20)와, 상기 양극 산화 처리 단계를 통해 총열 덮개(100)의 표면에 형성된 산화알루미늄 피막에 총열 덮개(100)의 인근 부품과 동일한 색상을 가지도록 염료를 착색하는 착색 단계(S30)와, 상기 착색 단계(S30)를 통해 염료가 착색된 총열 덮개(100)를 봉공하는 봉공 처리 단계(S40) 등을 포함하여 구성된다.As shown in FIG. 1, the method of manufacturing a gun barrel cover according to the present invention includes a barrel cover manufacturing step (S10) of manufacturing a gun barrel cover 100 by drawing an aluminum alloy 6061 material, and the barrel cover 100. An anodizing treatment step (S20) of forming an aluminum oxide film on the surface, and the aluminum oxide film formed on the surface of the gun barrel 100 through the anodic oxidation treatment step has the same color as the adjacent parts of the gun barrel 100. It includes a coloring step (S30) of coloring the dye, and a sealing process step (S40) of sealing the gun barrel cover 100 colored with dye through the coloring step (S30).

상기 총열 덮개 제조 단계(S10)는, 알루미늄 합금 6061 소재를 인발함으로써 총열 덮개(100)를 제조하는 것이다.In the gun barrel cover manufacturing step (S10), the gun barrel cover 100 is manufactured by drawing aluminum alloy 6061 material.

여기서, 총열 덮개 제조 단계(S10)에 의하여 제조된 총열 덮개(100)에는 추가적인 기계 가공이 더 수행될 수 있을 것이다.Here, additional machining may be performed on the barrel cover 100 manufactured in the gun barrel cover manufacturing step (S10).

이처럼, 총열 덮개 제조 단계(S10)에 의하여 제조된 총열 덮개(100)는, 알루미늄 합금 7075 소재를 단조함으로써 제조된 총기의 여타 부품(예컨데, 총열, 총몸 등)과는 상이한 색상이 나타나게 된다.In this way, the gun barrel cover 100 manufactured in the gun barrel cover manufacturing step (S10) appears in a different color from other parts of the gun (eg, barrel, gun body, etc.) manufactured by forging aluminum alloy 7075 material.

이에 따라, 총열 덮개 제조 단계(S10)를 통해 제조된 총열 덮개(100)는, 알루미늄 합금 7075 소재를 단조함으로써 제조된 총기의 여타 부품(총열 덮개의 인근에 위치한 부품)과 동일한 색상을 나타내기 위하여 알루미늄 합금 7075 소재와는 상이한 염료를 사용하여야 하는 것이다.Accordingly, the barrel cover 100 manufactured through the barrel cover manufacturing step (S10) is to display the same color as other parts of the firearm (parts located near the barrel cover) manufactured by forging aluminum alloy 7075 material. A different dye must be used than aluminum alloy 7075 material.

이와 같은, 총열 덮개 제조 단계(S10) 이후에는 양극 산화 처리 단계(S20)가 수행된다.After the barrel cover manufacturing step (S10), an anodizing treatment step (S20) is performed.

상기 양극 산화 처리 단계(S20)는, 총열 덮개 제조 단계(S10)를 통해 제조된 총열 덮개(100)를 양극에서 산화 처리하기 위한 것이다.The anodic oxidation treatment step (S20) is for oxidizing the gun barrel cover 100 manufactured through the gun barrel cover manufacturing step (S10) with an anode.

즉, 양극 산화 처리 단계(S20)는 총열 덮개(100)를 산화시킴으로써 총열 덮개(100)의 표면에 산화알루미늄(

Figure 112021130338768-pat00001
) 피막을 형성하는 구성이다.That is, the anodizing treatment step (S20) oxidizes the barrel cover 100 to form aluminum oxide (aluminum oxide) on the surface of the barrel cover 100.
Figure 112021130338768-pat00001
) It is a composition that forms a film.

여기서, 산화알루미늄의 피막은 20 ~ 30 μm의 두께를 가지는 것이 바람직하다.Here, the aluminum oxide film preferably has a thickness of 20 to 30 μm.

한번 더 설명하면, 양극 산화 처리 단계(S20)는 경질양극산화피막을 형성하기 위한 것이다.To explain one more time, the anodizing step (S20) is to form a hard anodic oxide film.

이처럼, 알루미늄 합금으로 이루어진 총열 덮개(100)의 표면을 산화시켜 산화알루미늄 피막을 형성함으로써 총열 덮개(100)의 내마모성과 내식성 등이 향상되게 되는 것이다.In this way, the surface of the gun barrel cover 100 made of aluminum alloy is oxidized to form an aluminum oxide film, thereby improving the wear resistance and corrosion resistance of the gun barrel cover 100.

이 때, 양극 산화 처리 단계(S20)에 의하여 총열 덮개(100)의 표면에 형성되는 산화알루미늄 피막은, 다공질을 갖게 된다.At this time, the aluminum oxide film formed on the surface of the gun barrel 100 through the anodizing step (S20) becomes porous.

한번 더 설명하면, 총열 덮개(100)의 표면에 형성된 산화알루미늄 피막은 미세한 홀을 갖게 되는 것이다.To explain one more time, the aluminum oxide film formed on the surface of the gun barrel cover 100 has fine holes.

이에 따라, 총열 덮개(100)의 표면에 산화알루미늄 피막을 형성한 다음으로 염료를 착색할 경우 산화알루미늄 피막이 갖는 미세홀의 내부에 염료가 착색되어 보다 미려한 색상을 얻게 된다.Accordingly, when an aluminum oxide film is formed on the surface of the gun barrel cover 100 and then colored with a dye, the dye is colored inside the microholes of the aluminum oxide film, resulting in a more beautiful color.

또한, 양극 산화 처리 단계(S20)에서는, 총열 덮개(100)의 표면에 20㎛ 내지 30㎛의 두께를 갖는 산화알루미늄 피막이 형성될 수 있도록 함이 바람직하다.Additionally, in the anodizing step (S20), it is desirable to allow an aluminum oxide film to be formed with a thickness of 20 μm to 30 μm on the surface of the gun barrel 100.

이와 같은, 양극 산화 처리 단계(S20) 이후에는 착색 단계(S30)가 수행된다.After the anodizing step (S20), a coloring step (S30) is performed.

상기 착색 단계(S30)는, 총열 덮개(100)에 염료를 통해 색상을 입히기 위한 것이다.The coloring step (S30) is to color the gun barrel 100 using dye.

이 때, 총열 덮개(100)에 입혀지는 색상은 총기의 여타 부품과 동일한 색상으로 이루어짐이 바람직하며, 적어도 유사한 색상이 나타날 수 있도록 함이 바람직할 것이다.At this time, the color applied to the barrel cover 100 is preferably the same as that of other parts of the firearm, and it is desirable to have at least a similar color.

그러나, 총열 덮개(100)와 총기의 여타 부품의 기본 색상(소재에 따른 색상)이 상이하므로, 상이한 염료를 사용하면서 동일한 색상이 나타날 수 있도록 해야 하는 것이다.However, since the basic colors (colors depending on the material) of the barrel cover 100 and other parts of the firearm are different, the same color must be displayed while using different dyes.

상기 염료는 주 염료와 보조 염료의 배합으로 이루어지며, 주 염료는 블랙 비케이 엑셀(Black BK Excel)이고, 보조 염료는 골드 엔(Gold N) 또는 딥 레드 엘(Deep Red L)임을 예로 한다.The dye is made up of a combination of a main dye and an auxiliary dye. For example, the main dye is Black BK Excel, and the auxiliary dye is Gold N or Deep Red L.

여기서, 블랙 비케이 엑셀(Black BK Excel), 골드 엔(Gold N), 딥 레드 엘(Deep Red L)은 'U.S. Specialty Color Corporation'社에서 판매되는 제품군의 일종이다.Here, Black BK Excel, Gold N, and Deep Red L are 'U.S. It is a type of product sold by Specialty Color Corporation.

더불어, 상기 주 염료는, 1L의 물에 블랙 비케이 엑셀(Black BK Excel)이 10g 만큼 배합된 것임을 예로 한다.In addition, as an example, the main dye is 10 g of Black BK Excel mixed in 1 L of water.

또한, 상기 주 염료의 수소이온농도(pH)는 6.0 내지 7.0으로 이루어짐이 바람직할 것이다.In addition, it is preferable that the hydrogen ion concentration (pH) of the main dye is 6.0 to 7.0.

더불어, 착색 단계(S30)는 10분 내지 20분 동안 이루어짐이 바람직할 것이다.In addition, it would be preferable that the coloring step (S30) be performed for 10 to 20 minutes.

이는, 총열 덮개(100)의 색상이 총기의 여타 부품과의 색상과 최대한 유사한 색상이 나타날 수 있도록 하기 위함이다.This is to ensure that the color of the barrel cover 100 is as similar as possible to the color of other parts of the gun.

이와 같은, 착색 단계(S30) 이후에는 봉공 처리 단계(S40)가 수행된다.After the coloring step (S30), a sealing process step (S40) is performed.

상기 봉공 처리 단계(S40)는, 양극 산화 처리 단계(S20) 및 착색 단계(S30)가 수행된 총열 덮개(100)에 형성된 미세홀을 봉공하기 위한 것이다.The sealing process step (S40) is for sealing the micro holes formed in the gun barrel cover 100 on which the anodizing process step (S20) and the coloring step (S30) were performed.

이는, 양극 산화 처리 단계(S20)에서 형성된 산화알루미늄 피막은 다공질이면서도 흡착성을 가지므로, 피막은 더러워지기 쉬우면서도 손에 달라붙기 쉽기 때문이다.This is because the aluminum oxide film formed in the anodizing step (S20) is porous and has adsorption properties, so the film is easy to get dirty and stick to hands.

더불어, 산화알루미늄 피막이 갖는 미세홀의 내부에 염료의 착색이 이루어진 경우에는 염료의 퇴색이 쉬이 일어나기 때문이다.In addition, if the dye is colored inside the microholes of the aluminum oxide film, the dye easily fades.

한번 더 설명하면, 봉공 처리 단계(S40)는 양극 산화 처리 단계(S20) 및 착색 단계(S30)가 수행된 총열 덮개(100)에 추가로 실링(Sealing)하는 것이다.To explain one more time, the sealing process step (S40) is to additionally seal the gun barrel cover 100 on which the anodizing process step (S20) and the coloring step (S30) were performed.

즉, 본 발명에 의한 총열 덮개의 제조 방법에서는 총열 덮개의 제조를 위해 알루미늄 합금 6061 소재를 이용하므로 원가가 저감되게 된 것이다.That is, in the manufacturing method of the gun barrel cover according to the present invention, the cost is reduced because aluminum alloy 6061 material is used to manufacture the gun barrel cover.

더불어, 본 발명에 의한 총열 덮개의 제조 방법에서는 염료 착색 단계를 통해 알루미늄 합금 6061을 이용하여 제조된 총열 덮개가 알루미늄 합금 7075 소재와 동일한 색상을 나타내게 된 것이다.In addition, in the method of manufacturing a gun barrel cover according to the present invention, a gun barrel manufactured using aluminum alloy 6061 exhibits the same color as aluminum alloy 7075 material through a dye coloring step.

이러한 본 발명의 범위는 상기에서 예시한 실시예에 한정되지 않고, 상기와 같은 기술 범위 안에서 당 업계의 통상의 기술자에게 있어서는 본 발명을 기초로 하는 다른 많은 변형이 가능할 것이다.The scope of the present invention is not limited to the embodiments illustrated above, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.
