Description
본 발명은 금속재의 트윈파이프(Twin Pipe)를 제조하기 위한 방법에 관한 것이다.The present invention relates to a method for producing a twin pipe of a metal material.
더욱 상세하게는, 롤 포밍(Roll Forming)법을 이용하여 스테인레스 스틸과 같은 금속판을 순차 이송시키면서 '8'자 형태의 트윈파이프를 제조할수 있도록 한 롤 포밍을 이용한 금속재의 트윈파이프 제조방법에 관한 것이다.More specifically, the present invention relates to a method for manufacturing twin pipes of metal material using roll forming, which enables to manufacture '8' shaped twin pipes while sequentially transferring a metal plate such as stainless steel by using roll forming method. .
일반적으로 트윈파이프는 유체의 이송이나 전선을 매설하는 것 보다는 일정한 길이로 절단하여 창문용 방범창이나 대문의 간살, 계단 또는 난간용 가이드 레일, 울타리 및 담장의 간살과 휀스 등으로 널리 사용된다.In general, the twin pipe is cut to a certain length rather than the transfer of fluid or embedding wires, and is widely used for the security of windows or gates, the guide rails for stairs or railings, the fences and fences of fences and fences.
이와 같은 트윈파이프는 하나의 파이프를 설치하는 것 보다 강도가 크고 외관이 미려하기 때문에 방범창이나 휀스 등에 주로 많이 사용된다.Such a twin pipe is mainly used for security windows or fences because of its strength and beautiful appearance than installing a single pipe.
이러한 트윈파이프는 재료에 따라 그 성형방법이 달라진다.Such twin pipes have different molding methods depending on the material.
즉, 합성수지재로 성형할 경우는 사출 또는 압출방법을 사용하고, 금속재의 경우에는 용접방법이 주로 사용된다.That is, injection molding or extrusion is used when molding from a synthetic resin material, and welding is mainly used for metal materials.
이중, 합성수지는 성형이 용이한 반면 강도가 취약한 단점이 있고, 금속재의 경우에는 사출 또는 압출이 어렵거나 또는 이러한 방법을 이용하여 제조한다 하더라도 경계면 및 금속의 표면에 흠집이 생겨 미관을 해치는 문제가 발생한다.Among them, synthetic resins are easy to mold but have weak strengths, and in the case of metal materials, injection or extrusion is difficult, or even if manufactured using such a method, scratches occur on the interface and the surface of the metal, thereby deteriorating the aesthetics. do.
종래, 금속재의 트윈파이프를 제조할 경우에는 상기한 바와 같은 용접 방법을 가장 많이 사용하였다.Conventionally, when manufacturing a twin pipe of a metal material, the welding method as mentioned above was used the most.
이 용접방법은 이미 성형된 2개의 금속파이프를 나란하게 고정시켜 놓고, 그 접촉면을 용접으로 접합하는 것이다.This welding method fixes two metal pipes already formed side by side, and joins the contact surfaces by welding.
그런데, 이와 같은 방법은 별도로 성형된 2개의 금속파이프가 용접에 의해 접합되는 것이므로 1개의 부재를 사용할 때 보다 오히려 강도가 취약하고, 장기간 사용하게 되면 용접부위의 변형이나 뒤틀림 등이 발생하여 외관을 불량하게 하며, 용접자국이 그대로 외부에 노출되어 미관을 해치는 문제점이 있었다.However, in this method, since two separately formed metal pipes are joined by welding, the strength is weaker than when one member is used, and when used for a long time, deformation or distortion of the welded part causes defects in appearance. And, the welding marks were exposed to the outside as it was a problem that hurts the beauty.
또한, 용접시의 열변형 및 흠집 등으로 인해 외관이 불량하므로 폴리싱(Polishing) 등의 표면처리를 요하게 되고, 금속 특유의 광택이 나지 않는 단점이 있었다.In addition, since the appearance is poor due to heat deformation and scratches during welding, surface treatment such as polishing is required, and there is a disadvantage in that the metal does not have a gloss characteristic.
본 발명은 이러한 문제점을 해결하기 위한 것으로 그 기술적인 과제는 롤 포밍 가공법을 이용하여 하나의 금속판으로 부터 트윈파이프를 제조할수 있는 트윈파이프의 제조방법을 제공함에 있다.The present invention is to solve this problem, the technical problem is to provide a method for producing a twin pipe that can produce a twin pipe from a metal plate using a roll forming method.

본 방법에 의하면, 트윈파이프가 하나의 금속판에 의해 성형되므로 강도가 크고 장기간 사용하더라도 비틀림 등의 현상이 발생하지 않으며, 용접 및 기계가공이 필요치 않아 금속의 표면에 흠집 등이 발생하지 않고, 미려한 외관 및 금속 특유의 광택을 얻을수 있다.According to this method, since the twin pipe is formed by a single metal plate, even if the strength is large and long-term use does not occur, such as twisting, welding and machining is not necessary, no scratches on the surface of the metal, beautiful appearance And metallic luster.
이하에서 본 발명을 첨부된 도면에 의거 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 롤 포밍 가공법에 의해 금속판(10)을 순차적으로 절곡 성형하는 상태를 나타낸 단면도이고, 도 2A 내지 도 2N은 금속판이 롤 포밍기에 장착된 성형롤러(20)를 통과하면서 절곡되는 상태를 나타낸 단면도이다.1 is a cross-sectional view showing a state of sequentially bending the metal plate 10 by the roll forming method of the present invention, Figures 2A to 2N is a metal plate is bent while passing through the forming roller 20 mounted on the roll forming machine It is sectional drawing which showed state.
도시한 바와 같이 본 발명은 일정한 폭(b)과 두께(t)를 갖는 평판형의 금속판(10)을 순차 이송시키면서 롤 포밍기에 장착된 다단의 성형롤러(20)를 통하여 'S'자 형태로 부터 점차 '8'자 형태로 절곡시켜 트윈파이프(30)를 제조하는 것이다.As shown in the figure, the present invention provides a 'S' shape through a multi-stage forming roller 20 mounted on a roll forming machine while sequentially transferring the flat metal plate 10 having a constant width b and thickness t. From then gradually bending to form the '8' to form a twin pipe (30).
금속판(10)은 일정한 폭(b)과 두께(t)를 갖는 스테인레스 스틸판이나 동판 및 알루미늄판 등이다.The metal plate 10 is a stainless steel plate, a copper plate, an aluminum plate, etc. which have a constant width b and thickness t.
상기 금속판(10)은 그 중심선으로 부터 양단부가 다수의 성형롤러(20)에 의해 점차 'S'자 형태로 부터 '8'자 형태로 대칭되게 절곡되어 최종적으로 트윈파이프(30)가 얻어진다.Both ends of the metal plate 10 are symmetrically bent from the 'S' shape to the '8' shape by the plurality of forming rollers 20 from the center line, thereby finally obtaining a twin pipe 30.
또한, 금속판은 벤딩이 용이하도록 그 양단과 몸체 사이에 약간의 클리어린스(Clearance, c)를 준다.In addition, the metal plate gives a slight clearance (c) between both ends and the body to facilitate bending.
롤 포밍기에 장착된 성형롤러(20)는 다단으로 설치되어 직선형태로 배열된다.The forming roller 20 mounted on the roll forming machine is installed in multiple stages and arranged in a straight line shape.
상기 성형롤러(20)는 좌,우 또는 상,하 한쌍으로 이루어지며, 금속판(10)의재질 및 두께에 따라 그 수가 가변된다.The forming roller 20 is made of a pair of left, right or up and down, the number of which varies depending on the material and thickness of the metal plate 10.
또한, 성형롤러는 그 형상에 따라 금속판도 같은 형상으로 벤딩되기 때문에 상기 금속판과의 마찰저항을 줄이기 위하여 구동이 용이하고 매끄러운 표면을 갖고 있어야 한다.In addition, since the forming roller is bent in the same shape according to its shape, it should be easy to drive and have a smooth surface in order to reduce frictional resistance with the metal plate.
제조시에는 일정한 폭(b)과 두께(t)로 절단된 금속판(10)을 폴 포밍기에 투입한후 순차 이송시키면서 다단의 성형롤러(20)를 통하여 '8'자 형상의 트윈파이프(30)를 제조한다.During manufacture, the metal plate 10 cut to a predetermined width (b) and thickness (t) is introduced into a pole forming machine, and then sequentially transferred to the twin pipe 30 having an '8' shape through a multi-stage forming roller 20. To prepare.
금속판(10)은 이송하는 도중 계속적으로 성형롤러(20)와 접촉하면서 그 중심선으로 부터 양단이 'S'자 형태로 절곡된 다음 계속해서 '8'자 형태로 절곡되어 원하는 형태의 트윈파이프(30)로 제조된다.The metal plate 10 is continuously in contact with the forming roller 20 during the transfer, and both ends are bent in an 'S' shape from the center line, and then continuously bent in a '8' shape to form a twin pipe 30 of a desired shape. Is manufactured).
제조가 완료된 트윈파이프(30)는 사용처의 용도에 맞게 그 길이를 조절하여 절단하면 된다.The completed twin pipe 30 may be cut by adjusting its length to suit the purpose of use.
상기와 같이 제조된 본 발명의 트윈파이프(30)는 다음과 같은 기능 및 작용을 하게 된다.The twin pipe 30 of the present invention manufactured as described above has the following functions and functions.
첫째, 본 발명의 성형법은 하나의 금속판(10)으로 부터 롤 포밍기를 거쳐 트윈파이프가 얻어지므로 종래의 용접 방법과는 달리 트윈파이프 자체가 하나의 단일체이므로 강도가 크고, 장기간 사용하더라도 변형이나 뒤틀림 등이 발생하지 않는다.First, in the forming method of the present invention, since twin pipes are obtained from a single metal plate 10 through a roll forming machine, the twin pipes themselves are one monolithic bodies, unlike the conventional welding method, and thus have a high strength, and even if used for a long time, deformation or distortion may occur. This does not happen.
또한, 도 3과 같이 양측이 대칭되는 '8'자 형태이므로 작용ㆍ반작용의 법칙에 의해 외력을 흡수할수 있는 완충효과가 뛰어나고, 용접방법에 비해 구조재로서훌륭한 강도를 유지하게 된다.In addition, as shown in Fig. 3, since both sides are symmetrical '8' shapes, the buffering effect of absorbing the external force is excellent by the law of action and reaction, and the strength of the structural material is maintained as compared with the welding method.
둘째, 성형롤러와의 구름접촉에 의해 벤딩이 완료되므로 표면처리가 필요없고, 긁힘 등이 발생하지 않아 매끄러운 표면이 유지되며, 금속 특유의 광택이 나기 때문에 미려한 외관이 형성된다.Second, since the bending is completed by the rolling contact with the forming roller, no surface treatment is required, and a smooth surface is maintained because no scratches are generated, and a beautiful appearance is formed because of the metallic unique luster.
셋째, 금속판의 몸체와 양단부 사이에 약간의 클리어린스가 형성되므로 벤딩작업이 용이하게 이루어진다.Third, a slight clearance is formed between the body and both ends of the metal plate to facilitate the bending work.
넷째, 전 공정이 자동화되어 생산성이 향상된다.Fourth, the entire process is automated to improve productivity.
이상에서 설명한 바와 같이 본 발명은 스테인레스 스틸과 같은 금속판을 롤 포밍기에 투입하여 순차 이송시키면서 'S'자 형태로 부터 점차 '8'자 형태로 절곡 성형하여 트윈파이프를 제조하게 된다.As described above, in the present invention, a metal pipe, such as stainless steel, is introduced into a roll forming machine, and subsequently bend-molded from an 'S' shape to an '8' shape while sequentially transferring a twin pipe.
따라서, 본 발명의 트윈파이프는 하나의 금속판에 의해 성형되므로 2개의 금속파이프를 접합하던 종래의 방법에 비해 강도가 크고 용접 및 기계가공 등이 필요치 않으며, 자체의 작용 및 반작용 법칙에 의해 외력에 대한 저항이 크고, 장기간 사용하더라도 변형이나 뒤틀림이 및 분리현상 등이 발생하지 않는다.Therefore, since the twin pipe of the present invention is formed by one metal plate, the strength of the twin pipes is higher than that of the conventional method of joining two metal pipes, and welding and machining are not required. The resistance is large and deformation, distortion and separation do not occur even after long-term use.
또한, 표면에 흠집이나 긁힘 등이 발생하지 않으므로 외관이 미려하고, 금속 특유의 광택을 낼수 있다.In addition, since scratches and scratches do not occur on the surface, the appearance is beautiful and the gloss peculiar to the metal can be obtained.
