본 발명은 일루미늄튜브의 아연코팅에 관한 것으로, 특히 화학반응 처리에 의한 3공정 습식방법이 아닌 압출공정에 아연코팅장치를 설치하여 1공정의 건조방법으로 처리할 수 있는 알루미늄튜브의 아연코팅 방법에 관한 것이다.The present invention relates to zinc coating of aluminum tubes, in particular, zinc coating method of aluminum tube which can be treated by one-step drying method by installing a zinc coating device in an extrusion process rather than a three-step wet method by chemical reaction treatment. It is about.
종래의 알루미늄튜브의 아연코팅방법은 알루미늄튜브를 완제품의 형태로 가공한 다음에 탈지공정으로 표면의 불순물을 제거하고 다시 플루오르화수소산과 플루오르화아연에 약간의 첨가제가 화합된 아연 코팅제를 알루미늄튜브에 화학반응 처리하여 표면을 아연코팅한 후에 알루미늄튜브 표면에 묻은 화학액을 세척하는 3공정 습식표면처리방법으로, 이러한 습식처리방법은 공정의 복잡성에 따른 제품 생산성이 저하 뿐만 아니라화학처리에 따른 환경공해 및 산재의 위험이 내포되어 있다.The conventional zinc coating method of aluminum tube is to process the aluminum tube in the form of a finished product, and then remove the impurities on the surface by degreasing process, and then chemically coat the zinc coating with aluminum fluoride and some additives to zinc fluoride. This is a three-step wet surface treatment method in which the chemical treatment on the aluminum tube surface is washed after the zinc coating on the surface by reaction treatment. This wet treatment method not only reduces product productivity due to the complexity of the process, but also environmental pollution and There is a risk of industrial accidents.
따라서 본 발명은 종래 기술이 아연코팅처리가 안된 알루미늄튜브를 사용하여 절삭(Cutting), 굽힘가공(Bending), 납땜(Brazing)등을 통하여 자동차용 알루미늄튜브를 만든 후, 다시 탈지 공정, 코팅공정, 화학액세척공정의 여러 단계를 수행하여 아연코팅된 알루미늄튜브를 완성하는데 따른 화학처리공정시의 환경공해와 산업재해의 예방 뿐만 아니라 불필요한 공정의 복잡화를 단순화하여 제품의 생산성을 향상시키기 위하여 자동차용 알루미늄튜브를 제조하는 압출기나 컨폼머시인(Conform Machine)의 다이스 선단(압출제품의 출구 전방)에 아연을 건식으로 코팅할 수 있는 장치를 인-라인(In-Line) 형태로 설치하여 알루미늄튜브가 압출 생산됨과 동시에 원하는 두깨의 아연코팅을 할 수 있도록 하는데 그 목적이 있다.Therefore, in the present invention, the aluminum tube for automobiles is made by cutting, bending, brazing, etc. using the aluminum tube without zinc coating, and then, again, a degreasing process, a coating process, In order to improve product productivity by simplifying the complexity of unnecessary processes as well as the prevention of environmental pollution and industrial accidents during the chemical treatment process of completing zinc-coated aluminum tubes by performing various steps of the chemical cleaning process. An aluminum tube is extruded by installing an in-line type device that allows dry coating of zinc on the die tip (in front of the exit of the extruded product) of the extruder for manufacturing a tube or the conform machine. The aim is to be able to produce zinc coating of the desired thickness at the same time it is produced.
이하, 본 발명의 구성 및 실시예에 따른 작용효과를 도면에 의거하여 설명하면 다음과 같다.Hereinafter, the operational effects according to the configuration and the embodiment of the present invention will be described with reference to the drawings.
우선 본 발명의 실시하기 위한 압출기(40)에 연결되어 사용되는 아연코팅장치(10)의 구성은, 제1도 및 제3도에 도시된 바와 같이 알루미늄튜브(20)를 생산하기 위한 압출기(40)의 다이스 선단 전방에 아연코팅장치(10)를 설치하는데 있어서, 그 구조는 상기의 아연코팅 장치(10)를 통과하는 알루미늄튜브(20)의 중심으로 인-라인 형태의 상하, 좌우에 스프레이건(Spray Gun : 12)을 형성하며, 또한 통과되는 알루미늄튜브(20)의 굵기에 다라 스프레이건(12)이 알루미늄튜브(20)를 중심으로 이동 조절될 수 있도록 위치조절장치(14)를 스프레이건(12)에 형성되고, 그 주위는 상기의 위치조절장치(14)가 부착된 상기 스프레이건(12)의 용사처리(아연코팅)시에 발생되는 분진을 포집하는 스프레이부스(Spray Booth : 18)로 구성된다.First, the configuration of the zinc coating apparatus 10 used in connection with the extruder 40 for carrying out the present invention is an extruder 40 for producing the aluminum tube 20 as shown in FIG. 1 and FIG. In the installation of the zinc coating device 10 in front of the die tip of the), the structure is a spray gun on the top, bottom, left and right sides of the in-line form centered on the aluminum tube 20 passing through the zinc coating device 10 (Spray Gun: 12), and also depending on the thickness of the aluminum tube 20 passed through the spray gun 12 position control device 14 so that the spray gun 12 can be moved and adjusted around the aluminum tube (20) Spray booths (18) formed at (12) and around the dust collecting dust generated during the thermal spraying (zinc coating) of the spray gun (12) to which the positioning device (14) is attached. It consists of.
상기와 같이 구성된 본 발명의 아연코팅장치(10)를 압출기의 다이스 선단은 압출제품 출구 앞에 설치하면 본 발명을 실시할 수 있는 장치가 완성된다.The die tip of the extruder, the zinc coating device 10 of the present invention configured as described above is installed in front of the exit of the extruded product is completed the device capable of carrying out the present invention.
상기와 같이 설치된 아연코팅장치(10)에 의해 자동차용 알루미늄튜브(20)의 아연코팅처리되는 공정을 보면, 우선 아연코팅된 자동차용 알루미늄튜브(20)를 제조 생산하기 위해 알루미늄잉곳(Ingot : 46)을 압출기(40)에 통과시켜 압출시키며, 이어 압출되어 나오는 알루미늄튜브(20)가 압출기(40)에 연결된 아연코팅장치(10)를 통과하게 되는데, 이때 통과되는 알루미늄튜브(20)의 상하, 좌우에 설치되어 있는 스프레이건(12)은 위치조절장치(14)에 의하여 알루미늄튜브(20)의 굵기에 따라 위치가 조절된 상태에서 표면코팅재로 사용되는 아연선재(16)를 용융시켜 고압으로 알루미늄튜브(20)의 표면에 용융 아연을 용사하여 아연코팅을 이룬다.Referring to the zinc coating process of the aluminum tube 20 for automobiles by the zinc coating device 10 installed as described above, ingot (Ingot: 46) to manufacture and produce zinc-coated automotive aluminum tube 20 first ) Is passed through the extruder 40 and extruded, and then the extruded aluminum tube 20 passes through the zinc coating device 10 connected to the extruder 40, wherein the upper and lower sides of the aluminum tube 20 to pass through, The spray guns 12 installed on the left and right sides of the aluminum are heated at high pressure by melting the zinc wire 16 used as the surface coating material in a state where the position of the spray gun 12 is adjusted according to the thickness of the aluminum tube 20 by the position adjusting device 14. The surface of the tube 20 is sprayed with molten zinc to form a zinc coating.
상기와 같은 알루미늄코팅은 압출되어 나온 알루미늄튜브(20)의 온도가 약 500℃ 정도가 되므로 스프레이건(12)에서 용사된 아연입자들이 알루미늄튜브(20) 표면에 융착하게 되어 아연코팅된 알루미늄튜브(20)가 완성되며, 최종적으로 냉각실(Cooling Chamber : 30)을 통과하면 본 발명의 방법에 따른 알루미늄튜브(20)의 아연코팅공정이 완료된다.In the aluminum coating as described above, since the temperature of the extruded aluminum tube 20 becomes about 500 ° C., the zinc particles sprayed from the spray gun 12 are fused to the surface of the aluminum tube 20 so that the zinc coated aluminum tube ( 20) is completed, and finally passed through the cooling chamber (Cooling Chamber: 30), the zinc coating process of the aluminum tube 20 according to the method of the present invention is completed.
한편 제1도 및 제3도에 도시된 바와 같이 알루미늄잉곳(46)을 사용하여 알루미늄튜브(20)의 압출 및 아연코팅하는 방법과 동일하게 알루미늄선재(44)가 재료인 경우는, 제2도에 도시된 것처럼 압출기(40) 대신 컨폼머시인(42)을 사용하여 압출하며, 그에 따른 아연코팅장치 및 작용효과는 동일하다.On the other hand, as shown in FIGS. 1 and 3, the aluminum wire 44 is made of the same material as in the extrusion and zinc coating of the aluminum tube 20 using the aluminum ingot 46. Extruder using a conformal machine 42 instead of the extruder 40, as shown in the zinc coating device and the effect according to the same.
따라서 본 발명의 알루미늄튜브의 아연코팅방법은 건식법의 1공정 처리로 공정개선을 하여, 종래의 습식법의 3공정처리에 의한 기술에서 반드시 행하는 공정인 환경공해 및 산업재해 문제를 내포하고 있는 탈지공정, 화학반응공정 등의 불필요한 공정을 생략하였으므로 환경공해 및 산업재해를 예방할 수 있으며, 또한, 연속적으로 아연코팅된 제품을 제조생산할 수 있어 제품 생산성에 큰 도움을 줄 뿐만 아니라, 스프레이건에 공급되는 아연선재의 공급량을 조절하여 제품의 코팅두께를 조절할 수 있다. 한편 종래의 화학반응을 거치는 습식법 3공정 아연코팅방법과 비교하여 본 발명의 건식법의 1공정 코팅방법에 따른 제품의 내식성의 차이는 없다.Therefore, the zinc coating method of the aluminum tube of the present invention is a degreasing step containing the environmental pollution and industrial accidents, which is a process necessarily performed in the technique by the three-step treatment of the conventional wet method by improving the process by one-step treatment of the dry method, Since unnecessary processes such as chemical reaction processes are omitted, it is possible to prevent environmental pollution and industrial accidents, and to manufacture and produce zinc coated products continuously, which not only helps product productivity greatly, but also provides zinc wire supplied to spray guns. The coating thickness of the product can be controlled by adjusting the supply amount of. On the other hand, there is no difference in corrosion resistance of the product according to the one-step coating method of the dry method of the present invention as compared to the wet method three-step zinc coating method through the conventional chemical reaction.
