알루미늄 코팅관 제조금형{Product Mold For Aluminum coating pipe}Product Mold For Aluminum coating pipe

본발명은 알루미늄 재질의 관 주위를 합성수지로 코팅하여 제작하는 알루미늄 코팅관 제조금형에 관한 것이다.The present invention relates to an aluminum coating tube manufacturing mold for producing by coating a synthetic resin around the aluminum tube.

일반적으로 특허등록번호 10-0887710호에 종래기술로 기재된 바와 같이, 배관용 관, 난간 및 울타리, 공공시설물에 설치하는 구조물 등에는 다양한 금속제 배관이 사용된다. 이러한, 금속제 배관은 부식을 막기 위해 표면에 구리도금이나 불소수지 코팅을 하기 때문에 원가가 높고 중량이 무거운 점이 있다. 따라서, 금속제 배관보다 가볍고 원가가 절감되는 알루미늄 튜브가 최근 많이 사용되고 있다.In general, as described in the prior art in Patent Registration No. 10-0887710, various metal pipes are used for pipes, railings and fences, structures installed in public facilities. Such metal pipes have a high cost and a heavy weight because copper plating or fluorine resin coating is applied to the surface to prevent corrosion. Therefore, aluminum tubes, which are lighter than metal pipes and which reduce costs, have been used in recent years.

하지만, 알루미늄 튜브의 경우에도 외부의 충격에 의해 내충격성이 약하며,알루미늄 튜브 내부의 가스,증기 등의 물질에 의하여 튜브용기가 부식될 수 있으며, 외관상으로 다양한 색상표현이 불가능하다. 따라서, 이러한 문제들을 해결하기 위하여 알루미늄 튜브에 폴리에틸렌,폴리아미드 등의 합성수지를 코팅하여 사용되고 있다.      However, even in the case of aluminum tubes, the impact resistance is weak due to external impact, the tube container may be corroded by the gas, vapor, etc. inside the aluminum tube, it is impossible to express various colors in appearance. Therefore, in order to solve these problems, a synthetic resin such as polyethylene or polyamide is coated on an aluminum tube.

따라서 본 발명은 상기와 같은 문제점을 해결하고자 안출된 것으로서, 알루미늄관 외주에 형성되는 코팅층의 두께를 자유롭게 조절할 수 있으므로, 생산성이 높고 제작단가가 낮으며 코팅층의 품질이 우수한 알루미늄 코팅관 제조금형을 제공하고자 하는 것이다.Therefore, the present invention has been made to solve the above problems, it is possible to freely control the thickness of the coating layer formed on the outer periphery of the aluminum tube, to provide a high productivity, low manufacturing cost, excellent coating layer quality of the aluminum coating tube manufacturing mold I would like to.

본발명은 알루미늄 코팅관 제조금형에 관한 것으로, 알루미늄관(10) 외주에 합성수지로 코팅하는 알루미늄 코팅관 제조금형에 있어서, 상기 코팅용 금형(20)은 암금형(21)과 수금형(22)으로 이루어지며, 특히 암, 수금형(21, 22) 모두 서로 닿는 면이 경사가 져 있는 것으로, 콘(CONE)형상을 이루고 있고, 상기 암금형(21)의 상부에 설치된 상기 수지용융액 주입구를 통하여 수지용융액이 주입됨으로, 상기 암금형(21) 내에 수금형(22)을 진입시키는 거리를 변경함으로써 코팅층(30) 두께를 자유롭게 조절할 수 있는 것을 특징으로 한다.The present invention relates to an aluminum coating tube manufacturing mold, in the aluminum coating tube manufacturing mold coated with a synthetic resin on the outer periphery of the aluminum tube (10), the coating die 20 is a female mold 21 and a metal mold (22) It is made of, in particular, the arm, the molds (21, 22) are both inclined in contact with each other, forming a cone (CONE) shape, through the resin melt inlet installed on the top of the female mold (21) Since the resin melt is injected, the thickness of the coating layer 30 can be freely adjusted by changing the distance for entering the collection mold 22 into the female mold 21.

또한, 상기 1차코팅완료된 1차코팅층(31)위에 재차 코팅을 하여 2차코팅층(32)을 형성하기 위하여, 상기 코팅장치는 1차 코팅장치(100)에 2차 코팅장치(200)가 연이어 설치되되, 상기 2차 코팅장치(200)도 코팅용 금형(20)과 수지용융액 주입구로 구성되며, 상기 코팅용 금형(20)은 콘 형상 암금형(21) 과 수금형(22)으로 이루어지는 것을 특징으로 한다.
In addition, in order to form the secondary coating layer 32 by coating again on the primary coating completed primary coating layer 31, the coating device is a secondary coating device 200 in the primary coating device 100 It is installed, but the secondary coating apparatus 200 is also composed of a coating mold 20 and a resin melt inlet, the coating mold 20 is formed of a cone-shaped female mold 21 and a water collecting mold 22 It features.

본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다. 도 1은 본발명의 코팅장치 개략도, 도 2는 본발명의 조절칸이 설치된 코팅장치 개략도, 도 3은 본발명의 알루미늄 코팅관 상세단면도이다.     The present invention will be described in detail with reference to the accompanying drawings. 1 is a schematic view of the coating apparatus of the present invention, FIG. 2 is a schematic view of a coating apparatus in which the control compartment of the present invention is installed, and FIG. 3 is a detailed cross-sectional view of the aluminum coating tube of the present invention.

본발명은 먼저 알루미늄관을 세정제를 사용하여 브러쉬로 세척하여 오물을 제거한다. 그리고 원적외선으로 예열을 하여 전처리한다. 예열은 알루미늄관에 미세하게나마 잔류해 있는 수분을 증발시켜 제거하고 그리고 표면에 부착된 불순물 제거하는 것이다. 그리고 합성수지를 1차 도포한다. 필요에 따라서 2차로 1차완료된 코팅층위에 2차 도포한다. 합성수지 재질은 PE, PP, PV(폴리염화비닐)중 어느 하나를 사용한다. 최적치는 1차 코팅층은 PE, 2차코팅층은 PP로 하여 접착성과 함께 내마모성, 내구성을 증대시킨다.     The present invention first removes dirt by washing the aluminum tube with a brush using a cleaning agent. And preheat by far infrared rays. Preheating is the evaporation and removal of the minute residual water in the aluminum tube and the removal of impurities on the surface. And synthetic resin is first applied. If necessary, apply a second coating on the second completed coating layer. Synthetic resin material is any one of PE, PP, PV (polyvinyl chloride). The optimum value is PE with primary coating layer and PP with secondary coating layer increases adhesion and wear resistance and durability.

한편, 예열 후 코팅전에 알루미늄관 표면에 미세금을 형성하여, 접착성을 높일 수 있는 것으로, 상기와 같이 미세금을 형성하는 방법은 다수 개의 날이 표면에 형성된 두 개의 롤러 사이로 알루미늄관을 통과시킴으로서 표면에 미세금을 형성할 수 있다.     On the other hand, after preheating, the fine gold is formed on the surface of the aluminum tube before coating, thereby improving adhesion. The method of forming the fine gold as described above is performed by passing an aluminum tube between two rollers having a plurality of blades formed on the surface thereof. Fine gold can be formed on the surface.

또한 널링공구를 이용한 널링(KNURLING)방식에 의해 요철부를 알루미늄관 표면에 형성하여 접착성을 높일 수 있다.      In addition, by the knurling (KNURLING) method using a knurling tool can form an uneven portion on the surface of the aluminum tube to improve the adhesion.

코팅용 금형은 암금형과 수금형으로 나누어지며, 특히 암, 수금형 모두 서로 닿는 면이 경사가 져 있는 것으로, 콘(CONE)형상을 이루고 있다. 그리고 암금형의 상부에서 수지용융액이 주입된다.     Coating molds are divided into female molds and collection molds, and in particular, the arms and the molds are inclined to contact with each other, forming a cone shape. And a resin melt is injected from the upper part of the female mold.

본발명에서 암수금형이 콘 형상을 이루고 있으므로, 암금형 내에 수금형을 진입시키는 거리를 변경함으로써 코팅층 두께를 자유롭게 조절할 수 있다. 상기 코팅용 금형은 두 개정도로 만들어 순차적으로 배치함으로써 2중 코팅을 행할 수 있다.     Since the female mold has a cone shape in the present invention, the thickness of the coating layer can be freely adjusted by changing the distance for entering the mold into the female mold. The coating die may be double coated by sequentially making two revisions.

그리고 본발명은 1차 코팅장치와 2차 코팅장치 사이에 투명튜브로 제작된 조절칸을 설치한다. 조절칸은 튜브형태이며 투명한 재료로 만들어져서 내부를 볼 수 있게 구성되며, 또한 외부와 격리하여 이물질들이 조절실 내부로 들어가는 것을 방지한다. 그러므로 1차 코팅장치에서 1차코팅층이 형성된 후, 작업자는 1차코팅층의 상태를 쉽게 관찰할 수 있다.      And the present invention installs a control box made of a transparent tube between the primary coating device and the secondary coating device. The control box is tubular and is made of transparent material so that the inside can be seen and is isolated from the outside to prevent foreign substances from entering the control room. Therefore, after the primary coating layer is formed in the primary coating device, the operator can easily observe the state of the primary coating layer.

그리고 조절칸 내부에는 전기히터를 설치함으로써 1차코팅층을 필요에 따라서 가열하여 코팅층의 품질을 향상할 수 있다. 그리고 조절칸 내부에는 반응가스를 주입하거나 코팅물질을 분무상태로 주입하여 1차코팅층과 반응시킬 수 있다. 필요에 따라서는 1차 코팅장치에서는 코팅작업을 하지 않고 조절칸에서 코팅물질을 분무상태로 주입하여 표면 전처리를 할 수 있다. 그리고 필요에 따라서 진공펌프를 연결하여 내부를 진공으로 형성할 수 있다.     And by installing an electric heater in the control compartment, the primary coating layer can be heated as needed to improve the quality of the coating layer. In addition, a reaction gas may be injected into the control compartment or a coating material may be injected in a spray state to react with the primary coating layer. If necessary, in the primary coating device, the surface may be pretreated by spraying the coating material in the control chamber without coating. And if necessary, it can be connected to a vacuum pump to form the inside of the vacuum.

따라서 본발명은 알루미늄관 외주에 형성되는 코팅층의 두께를 자유롭게 조절할 수 있으므로, 생산성이 높고 제작단가가 낮으며 코팅층의 품질이 우수하다.     Therefore, the present invention can freely adjust the thickness of the coating layer formed on the outer circumference of the aluminum tube, the productivity is high, the manufacturing cost is low, the coating layer quality is excellent.
