본 고안은 에어실린더나 복사기드럼 등으로 이용되는 알루미늄파이프의 내외측면에 양극산화 피막을 형성하는 양극산화 피막처리장치에 관한 것이다.The present invention relates to an anodizing film treatment apparatus for forming an anodized film on the inner and outer sides of an aluminum pipe used for an air cylinder, a copier drum, and the like.

주로 알루미늄파이프로 성형제작되는 에어실린더나 복사기드럼등은 매끈하고 미려한 표면유지 및 심한 마찰에도 견딜수 있는 강한 경도를 얻기 위하여 내외면에 양극산화피막층이 형성된다.Air cylinders and copier drums, which are mainly made of aluminum pipes, are formed with anodized layers on the inner and outer surfaces to obtain a smooth and beautiful surface and strong hardness to withstand heavy friction.

또한 알루미늄제품에 형성되는 양극산화피막층은 피막처리시 주어지는 전류와 전압 및 시간 등에 비례하여 경도와 두께가 결정되는데 큰 경도를 요하지 않을 경우 색상을 최우선시하여 알루미늄 고유의 미려한 유백색이 가장 잘 나타나는 약15미크롬 두께의 피막층을 갖도록 하는 것이면 만족하나 에어실린더와 복사기드럼등과 같이 사용시 심한 마찰력이 주어지는 내면은 25미크롬 이상의 두께로서 비커스 경도Hv350이상의 경질 피막층이 요구된다.In addition, the anodized layer formed on the aluminum product has a hardness and thickness determined in proportion to the current, voltage, and time given during the film treatment.If large hardness is not required, the color is given the highest priority, so that the beautiful milky white characteristic of aluminum is best displayed. It is satisfactory to have a film layer having a thickness of chromium, but the inner surface to which severe frictional force is given during use such as an air cylinder and a copier drum is required to have a thickness of 25 microns or more and a hard film layer having a Vickers hardness of Hv350 or more.

그러나 이제껏 이용되고 있는 알루미늄파이프의 양극산화 피막처리장치는 긴전해조의 상부중앙에 절연상태로 길게 거치되는 양극대에 파이프를 촘촘히 연결하고 그 음극대가 갖는 음극봉은 파이프 내에 삽입되게하며 전해조 양측 상부에 갖는 음극대에는 음극판을 촘촘히 형성하여 한대의 정류기를 통한 전력공급으로 황산용액의 전기분해에 의해 양극산화피막층이 형성되도록 하고 있다.However, the anodic oxidation film treatment apparatus of aluminum pipes which have been used so far is closely connected to the anode pole which is long insulated in the upper center of the long electrolytic cell, and the cathode rod of the cathode cell is inserted into the pipe, An anode plate is formed on the cathode plate to form an anodized layer by electrolysis of sulfuric acid solution by power supply through a single rectifier.

따라서 이러한 구조의 양극산화 피막처리장치는 내외면 같은 경도와 두께의 피막층을 형성해주는데에는 전혀 무방하나 에어실린더나 복사기드럼등과 같이 내면은 심한 마찰력에도 견딜수 있는 강한 경도의 두꺼운 피막층이 요구될 경우 내외측 피막층두께를 달리해줄 수가 없어 강한 경도가 요구되는 내측 피막층을 기준으로 강한 전력을 공급하여 내외측 구분없이 강한 경도의 두꺼운 피막층을 형성해주어야하므로 불필요한 전력 낭비를 가져오게 되고 그 외면의 색상은 알루미늄 고유의 유백색을 상실하고 회색을 띠게 되므로 외관이 미려하지 못한 문제점들이 발생된다.Therefore, the anodizing film treatment device having such a structure has no problem in forming a coating layer having the same hardness and thickness as the inside and outside surfaces, but when a thick film layer having a strong hardness such as an air cylinder or a copier drum is required to withstand severe frictional forces, Since the outer film layer thickness cannot be changed, strong electric power must be supplied based on the inner film layer that requires strong hardness to form a thick film layer of strong hardness without distinguishing between inner and outer sides, resulting in unnecessary waste of power and the color of the outer surface is unique to aluminum. The loss of milky white and grey, so the appearance is not beautiful problem occurs.

이로 인하여 일부 업체에서는 내외측피막층의 두께를 달리하는 제품의 가공시 외측피막층 형성용 음극판을 일부 제거하여 듬성듬성 형성되게 한 상태에서 강한 전력을 공급하여 내면은 경도가 강한 두꺼운 피막층이 형성되게 하고 외면은 음극판의 면적 차이로 연질의 얇은 피막층이 형성되도록하고 있으나, 이러한 경우 필요에 따라 음극판을 탈부착하는데 많은 번거로움이 따르게되고 이 역시 불필요한 전력낭비를 가져오게되며 특히 음극판의 간격이 넓어진만큼 극간거리와 표면적 등의 차이로 인하여 각 제품간에는 물론 제품의 부위별 피막층의 두께 편차가 심하고 또 이는 곧 피막층의 두께에 의해 결정되는 색상차이로 이어져 제품의 품질저하를 하져오게되는 등의 문제점들이 있는 것이다.For this reason, some companies remove some of the outer film layer forming negative electrode plate and make it sparsely formed when processing products having different thicknesses of the inner and outer coating layers. Silver thin film layer is formed by the difference of the area of the negative electrode plate, but in this case, it takes a lot of trouble to attach and detach the negative electrode plate as necessary, which also leads to unnecessary power consumption, especially the gap between the negative electrode plate and the gap between Due to the difference in surface area, there is a problem in that the thickness variation of the coating layer for each part of the product, of course, is severe, which leads to a color difference determined by the thickness of the coating layer, resulting in deterioration of the product quality.

본 고안은 상술한 종래기술이 갖는 재반 문제점들을 해결하기 위하여 전력소모량을 줄이면서 내외측 피막층의 두께를 달리할 수가 있고 또 내외측 각각 피막층의 두께 편차를 없애줄 수가 있어 제품의 품질을 향상시켜줄수가 있는 알루미늄파이프의 양극산화피막처리장치를 제공하고자 한다.The present invention can improve the quality of the product by reducing the thickness of the inner and outer coating layer while reducing the power consumption in order to solve the problems of the prior art described above, and can eliminate the thickness variation of the inner and outer coating layers, respectively. An object of the present invention is to provide an anodizing apparatus for aluminum pipes.

상기한 목적달성을 위하여 본 고안은 전해조의 상부중앙에 갖는 양극대와 음극대를 제1정류기와 접속하고, 상기 양극대와 전해조 양측상부에 갖는 음극대는 제2정류기와 접속하여 알루미늄파이프의 내외면에 서로 다른 전력에 의한 전해용액의 전기분해로 피막층이 형성되게 한 양극산화 피막처리장치에 의해 달성된다. In order to achieve the above object, the present invention connects the positive electrode and the negative electrode in the upper center of the electrolytic cell with the first rectifier, and the negative electrode having the positive electrode and the upper part on both sides of the electrolytic cell is connected with the second rectifier in the inner and outer surfaces of the aluminum pipe.

The negative electrode rod 20 is formed to be connected to the cathode pipe 12 without the large movement of the aluminum pipe (A) is connected between the tight connecting piece (10a) and the locking portion (20a) having the positive pole 10 is formed.

또한 전해조(2) 상부양측에 갖는 음극대(6)(8)의 음극판(6a)(8a)은 판형으로서 촘촘히 연결형성된다.In addition, the negative electrode plates 6a and 8a of the negative electrode bands 6 and 8 provided on both sides of the upper part of the electrolytic cell 2 are closely connected in a plate shape.

본 고안은 적정길이로 절단된 알루미늄파이프(A)의 하단부에 각기 받침대 (20)가 갖는 걸림돌부(20a)가 헐겁게 결합되게하고 그 상단부는 캐리어바(4)의 양극대(10)가 갖는 연결편(10a)에 클립이나 볼트넛으로 연결고정되게하며 각 알루미늄파이프(A)내에는 음극대(12)가 갖는 음극봉(12a)이 삽입되게 한 상태에서 전해액이 충전된 전해조(2)에 삽입하여 중앙부에 거치하고 캐리어바(4)가 갖는 양극대(10)와 음극대(12)는 제1정류기(14)와 접속하고 상기 양극대(10)와 전해조 양측의 음극대(6)(8)는 제2정류기(16)와 접속되게 하여 제1, 2정류기(14)(16)를 통하여 전력을 공급해주는 것으로 알루미늄파이프(A)의 내외면에 양극산화 피막층이 형성된다.The present invention is to loosely coupled to the lower end of the aluminum pipe (A) cut to the appropriate length, respectively, 20b of the pedestal 20, the upper end of the connecting piece having the positive pole 10 of the carrier bar (4) It is inserted into the electrolytic cell (2) filled with the electrolyte in a state that the connection to the clip (10a) and fixed with a clip or bolt nut and the negative electrode rod (12a) of the negative electrode band 12 is inserted in each aluminum pipe (A) The positive electrode 10 and the negative electrode 12 mounted on the center portion of the carrier bar 4 are connected to the first rectifier 14, and the positive electrode 10 and the negative electrode 6 on both sides of the electrolyzer are connected. Is connected to the second rectifier 16 to supply power through the first and second rectifiers 14 and 16, and anodization layer is formed on the inner and outer surfaces of the aluminum pipe A.

You can get it.

또한 에어실린더나 복사기드럼 등과 같이 제품이 갖는 특성상 외면은 미려한 외관유지만으로 만족하나 내면은 강한 경도의 두꺼운 피막층이 요구될 경우 제1정류기(14)의 전력공급량은 증가시키고 제2정류기(16)의 전력공급량은 축소시켜주게되면 원하는 결과를 얻게된다.In addition, due to the characteristics of the product such as an air cylinder or copier drum, the outer surface is satisfied with only a beautiful appearance, but when the thick film layer having a strong hardness is required on the inner surface, the power supply of the first rectifier 14 is increased and the second rectifier 16 is If you reduce the power supply, you get the desired result.

이때 알루미늄파이프(A)외면이 갖는 피막층은 연질의 얇은 두께로서 제2정류기(16)를 통하여 이에 적절한 전력을 공급해주는 것으로 만족하므로 전력낭비를 방지할 수가 있고 또 전해조(2)양측에 갖는 음극대(6)(8)의 음극판(6a)(8a)은 촘촘히 형성되어있어 극간거리와 표면적의 차이를 최소한 시켜줄수 있는만큼 피막층의 편차없이 전체적으로 알루미늄 고유의 유백색을 띠게되어 미려한 외관을 지닐수 있게 되는 것이다.At this time, the film layer of the outer surface of the aluminum pipe (A) is a soft thin thickness and satisfies that the appropriate power is supplied through the second rectifier 16, thereby preventing the waste of power and having a negative electrode band on both sides of the electrolytic cell (2).
