Abstract
Description
본 발명은 내부에 유체(예컨대 물, 가스, 키타, 화학물질)가 흐르는 배관의 연결부를 타 배관연결부와 용이하게 체결시키기 위해 단부를 압착 또는 성형 가공하여 플랜지를 형성시킴에 있어서,The present invention is to form a flange by pressing or molding the end portion in order to easily connect the connecting portion of the pipe in which fluid (for example, water, gas, kita, chemicals) flows with other pipe connecting portion,
배관을 구성하는 주름관을 환상 주름부분, 민자부분, 나선형 주름부분 때로는 민자부분을 일체 성형하여 이를 환상 주름부분이나 민자부분을 절단한 후 그 단부를 압착 또는 성형 플랜지를 가공하여 체결시키기 용이한 배관용 주름관의 성형방법에 관한 것이다.For pipes that make it easy to fasten the corrugated pipe constituting the pipe by cutting annular wrinkles, private sectors, spiral wrinkles, and sometimes private sectors and cutting them into annular wrinkles or private sectors It relates to a molding method of the corrugated pipe.
주지된 바와 같이 종래에는 유체 이송용 배관시에는 환상용 주름관(1)과 나선형 주름관(2) 및 직관(3)을 복합사용하지 않고 단일로 사용하였다.As is well known, the annular corrugated pipe (1), the spiral corrugated pipe (2), and the straight pipe (3) were used as a single unit in the conventional fluid transfer piping.
즉 환상형 주름관(1)의 경우 구조적으로 유체 이송시 저항이 크고 뒤틀림 흡수 능력이 나선형 주름에 비해밖에 지나지 않아 파손의 우려가 컸으나 주름이 환상으로 구성되어 있기 때문에 단부의 압착이 용이하여 압착부(6)에 의한 취부가 편리하였으므로 주로 많이 사용하고 있으며, 나선형 주름관(2)의 경우 유체이송이 저항이 적고 뒤틀림 흡수 능력이 양호하여 환상형 주름관(1)에 비해 장점이 많으나 주름이 나선상으로 구성되어 있기 때문에 단부의 압착이 불가능하여 압착부(6)에 의해 취부가 어려웠던 결점이 있었고 직관(3)의 경우에는 플랙시블하지 않아 굴곡부분이 많은 배관용으로 적합하지 않았다.In other words, in the case of the annular corrugated pipe (1), the structural resistance is high and the distortion absorption capacity is higher than that of the spiral corrugated pipe. There was only a high risk of breakage, but since the folds were annular, the end was easily crimped, and the mounting by the crimping part 6 was convenient, so it is mainly used. It has a small and good twist absorbing ability, and thus has many advantages over the annular corrugated pipe (1). However, since the crimp is formed in a spiral shape, the end portion cannot be crimped. In the case of, it is not flexible and it is not suitable for piping with many bends.
따라서 도4에 도시한 바와 같이 나선형 주름관(1)으로 성형된 관으로 배관할 때는 그 절단부분(11)에 별도의 환상형 주름이나 민자부분을 형성 또는 용접하여 그 용접부분(4)의 주름부분이나 민자부분을 압착 또는 가공하여 플랜지(10)를 형성시킨 후 연결하였기 때문에 그 용접비와 가공비가 고가여서 배관비용이 고가가 되는 원인이 되었다.Therefore, as shown in Fig. 4, when the pipe is formed into a spiral corrugated pipe 1, a separate annular pleat or a privately formed portion is formed or welded to the cut portion 11 so that the pleated portion of the welded portion 4 is formed. In addition, since the flange 10 was formed by crimping or processing the private parts, the welding cost and the processing cost were high, causing the piping cost to be expensive.
또한 나선형 주름관(1)의 단부를 민자상태로 펴준 후 플랜지(10)를 가공하는 방식의 경우 그 펴주는 비용 역시 나선형 주름관1M 생산비와 거의 같았으며 플랜지 가공비가 주름관1M 펴주는 비용의 20%정도 별도로 추가되었으므로 설치비가 많이 들었다.In addition, in the case of processing the flange 10 after the end of the spiral corrugated pipe 1 is uncivilized, the unfolding cost is almost the same as the cost of producing the spiral corrugated pipe 1M, and the processing cost of the flange is about 20% of the cost of straightening the corrugated pipe 1M. It was expensive to install because it was added.
상기한 바와 같이 본 발명은 배관을 체결하는데 편리하도록 나선형 주름관의 단부에 압착부나 플랜지를 가공키 위해 용이하도록 환상 주름부분, 나선형 주름부분 중간에 민자부분을 삽입하여 일체 성형하여 필요에 따라 환상 주름부분 및 민자부분을 절단하여 된 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.As described above, the present invention provides an annular pleated portion and an annular pleated portion inserted in the middle of the helical pleated portion so as to easily process a crimping portion or a flange at the end of the helical corrugated tube so as to conveniently fasten the pipe. And it was made by cutting the private sector portion described in detail according to the accompanying drawings as follows.

첨부도면 중 도1-도5는 종래의 주름관에 대한 단면도 이고,1 to 5 of the accompanying drawings is a cross-sectional view of a conventional corrugated pipe,
도6-도9는 본 발명의 주름관에 대한 측면도와 사시도이다.6 and 9 are side and perspective views of the corrugated pipe of the present invention.
즉 통상의 주름관을 성형하는 방법으로 환상형 주름부분(7)과 민자부분(9) 및 나선형 주름부분(8) 순으로 일체 성형하되, 상기 환상형 주름부분(7)과 민자부분(9)은 비교적 짧게 하고 (예컨대 환상형 주름부분의 경우 약 5-7의 골정도, 민자부분의 경우 반으로 절단하여 플랜지(10)에 너트(5)를 결합시킬 정도의 길이) 나선상 주름부분(8)은 주배관에 해당되므로 소정의 길이만큼 길게 구성하였다.That is, the annular corrugation part 7 and the private capital part 9 and the spiral corrugation part 8 are integrally molded in the order of forming a conventional corrugated pipe, but the annular corrugation part 7 and the private part part 9 are It is relatively short (e.g., about 5-7 bones in the annular corrugation, about half the length in the private sector, and the length of joining the nut 5 to the flange 10). Corresponding to the main pipe was configured as long as a predetermined length.
도면 중 미 설명 부호는 11, 11a는 절단부위, 12는 파이프이다.In the drawings, reference numerals 11 and 11a denote cut portions, and 12 denote pipes.
이와 같이 구성된 본 발명의 성형방법에 대해 구체적으로 설명한다.The shaping | molding method of this invention comprised in this way is demonstrated concretely.
본 발명을 설명하려면 일정 형태를 가진 금형 내에 피이프(12)를 넣고, 파이프(12) 내의 충진물을 확압시키는 방법과 파이프(12) 내부에 금형을 넣고 파이프(12) 외부에서 프레싱하는 방법으로 하게 된다.To describe the present invention, the pipe 12 is placed in a mold having a certain shape, the method of pressurizing the filling in the pipe 12 and the method of putting the mold inside the pipe 12 and pressing the pipe 12 outside. do.
따라서 배관용 파이프(12)의 금형을 환상형 주름부분(7), 나선형 주름부분(8) 또는 중간에 민자부분을 위치시켜 이를 순차적으로 가공하는데, 즉 환상형 주름부분(7)은 약5-7골정도, 민자부분의 경우 반으로 절단하여 가공한 플랜지(10)에 너트(5)를 끼워 체결될 수 있을 정도의 길이가 되도록 하고, 나선상 주름부분(8)은 주배관이 되므로 소정의 길이가 되도록 한 후 필요에 따라 환상형 주름부분(7)이나 민자부분(9)의 중간부위를 절단하고 이 절단부위(11)(1la)를 압착하거나 가공한 플랜지(10)에 결합너트(5)를 끼워 타 배관 파이프에 체결하였던 것이다.Therefore, the mold of the pipe 12 is placed in an annular pleat (7), helical pleat (8) or in the middle of the private sector to process it sequentially, that is, the annular pleat (7) is about 5- About 7 bones, in the case of the private sector, cut the length of the half so that the nut (5) is fitted to the machined flange (10) to be fastened, and the helical corrugated portion (8) becomes the main pipe, so that a predetermined length After cutting, cut the intermediate portion of the annular corrugated portion 7 or the privately-induced portion 9 as necessary, and attach the coupling nut 5 to the flange 10 on which the cut portion 11, 1la is pressed or processed. It was fastened to the other pipe.
이와 같이 본 발명은 배관을 구비하는 파이프(l2) 자체를 환상형 주름부분(7)과, 민자부분(9) 및 나선형 주름부분(8)을 형성하여 주므로 간편히 절단부위(11)(11a)만 절단하여 환상형 주름부분(7)을 압착하거나 민자부분(7)을 가공하여 플랜지(10)에 결합너트(5)를 끼워 다른 배관 파이프와 체결시켜주기만 하면 견고한 배관이 이루어지게 되므로 종래와 같이 나선형 주름관 또는 직관을 형성시키거나 용접한 후 플랜지를 가공하는 불필요한 비용과 번거로움으로부터 탈피할 수 있어 배관 비용을 절감할 수 있는 잇점이 있다.As such, the present invention forms the pipe (l2) itself with a pipe to form an annular corrugated portion (7), a private sector portion (9) and a spiral corrugated portion (8), so that only the cut portions (11, 11a) By cutting the annular corrugation portion 7 or by processing the private sector portion 7, inserting the coupling nut 5 on the flange 10 and fastening it with other piping pipes, a rigid pipe is formed. After forming or welding corrugated pipes or straight pipes, it is possible to avoid the unnecessary cost and hassle of machining a flange, thereby reducing the pipe cost.
상술한 바와 같이 한 배관 파이프에 환상형 주름부분과 나선형 주름을 때로는 중간에 민자부분을 삽입 동시에 성형하여 요구에 따라 적당한 위치로 절단하여 그 절단부위를 압착하거나 성형 가공하여 플랜지를 구성케하여 통상의 결합너트를 체결할 수 있게 하여 나선형 주름관의 유체저항감소와 뒤틀림에 견디는 성능향상을 가지면서 동시에 환상형 주름관 또는 직관의 체결 기능 우위를 동시에 겸할 수 있어 타 배관 파이프와 체결함이 간편하고 신속하며 저렴한 비용으로 배관을 이룰 수 있는 등의 제반 효과가 있다.As described above, the annular corrugation part and the spiral corrugation part are sometimes inserted at the same time into the pipe pipe, and the private part is formed at the same time, and then cut to the appropriate position as required, and the cutting part is compressed or molded to form a flange. The coupling nut can be tightened to reduce the fluid resistance of the spiral corrugated pipe and improve the performance of warping, and at the same time, it has the advantage of the fastening function of the annular corrugated pipe or the straight pipe. There are various effects, such as making a pipe at a cost.
