Description

공간 보강대를 갖는 디씨 파이프의 성형방법{Formation method of the D C pipe which has the spatial reinforcement unit}Formation method of the DC pipe having a spatial reinforcement unit which has the spatial reinforcement unit}

본 발명은 공간 보강대를 갖는 디씨(DC) 파이프의 성형방법에 관한 것으로, 더욱 상세하게는 같은 간격으로 연속해서 성형하는 돌출부의 공간부에 같은 간격으로 다수개의 공간 보강대를 세워서 디씨 파이프의 강도를 크게 향상시킬 수 있도록 하는 공간 보강대를 갖는 디씨 파이프의 성형방법에 관한 것이다.The present invention relates to a method of forming a DC (DC) pipe having a space reinforcing bar, and more particularly, to increase the strength of the DC pipe by establishing a plurality of space reinforcing bars at the same interval in the space portion of the protrusion to be continuously formed at the same interval It relates to a method for forming a DC pipe having a space reinforcing table to be improved.

일반적으로 하수를 이동하기 위한 유로를 형성하는 하수관, 집수관, 배수관은 폴리에틸렌(PE), 폴리염화비닐(PVC) 등의 합성수지재로 성형하고, 내경 보강부(14)의 외경으로 공간부(13)를 갖는 돌출부(11)와 요홈부(12)가 연속해서 형성되면서 내경 보강부와 돌출부가 일체로 접합된 이중벽관으로 이루어진 디씨 파이프를 주로 사용한다.In general, the sewer pipe, the collection pipe, and the drain pipe forming a flow path for moving the sewage are formed of a synthetic resin material such as polyethylene (PE) and polyvinyl chloride (PVC), and the space portion 13 by the outer diameter of the inner diameter reinforcing portion 14. As the protrusions 11 and the recesses 12 having a) are continuously formed, a DC pipe made of a double wall tube in which the inner diameter reinforcing portion and the protrusion are integrally bonded is mainly used.

상기 디씨 파이프에는 소켓, 이음관, 연결관 등과 같은 관 연결부재를 통해서 축방향으로 연장되며, 관 연결의 수밀성을 보장하기 위해 디씨 파이프와 연결부 재 사이에 패킹을 사용한다.The DC pipe extends axially through pipe connecting members such as sockets, joint pipes, connecting pipes, and the like, and uses packing between the DC pipe and the connecting material to ensure the watertightness of the pipe connection.

이러한 종래의 디씨 파이프를 생산하는 공정에서 자켓 금형이 합쳐지는 이음매 부위에 소정의 단차가 발생하여 외부가 매끄럽지 못한 현상이 발생하고, 자켓 금형의 요홈부 간격이 KS 규격에 정해지지 않은 치수이므로 생산하는 회사마다 돌출부와 요홈부의 간격과 형상이 조금씩 차이를 가지고 있다.In the process of producing conventional DC pipes, a predetermined step occurs in the joint area where the jacket molds are joined, thereby causing a phenomenon in which the exterior is not smooth. The gap between the grooves of the jacket molds is not defined in the KS standard. The spacing and shape of the protrusions and grooves are slightly different each time.

그리고 돌출부와 요홈부는 측면에서 원형으로 성형되는 것이며, 소정의 두께를 갖도록 자켓 금형에 의해 성형되지만, 너무 두껍게 성형하는 경우 원료의 소모량이 너무 많게 되므로 되도록 얇게 성형하면서 강도를 향상시킬 수 있도록 하는 노력을 한다.And the protrusions and the grooves are formed in a circular shape on the side, but is molded by the jacket mold to have a predetermined thickness, but when forming too thick, the consumption of the raw material is too much, so efforts to improve the strength while forming as thin as possible do.

그렇지만, 두께를 얇게 성형하면서 강도를 향상시키는 것이 매우 어렵게 되므로 더욱 높은 강도를 요구하는 경우에는 돌출부의 외경으로 내경 보강부와 같이 평활한 외경 보강부를 압출에 의해 성형하여 전체적으로 삼층관을 성형하게 된다.However, since it is very difficult to improve the strength while forming a thin thickness, when a higher strength is required, a smooth outer diameter reinforcing part, such as an inner diameter reinforcing part, is formed by extrusion into the outer diameter of the protrusion to form a three-layer pipe as a whole.

그러나 삼층관을 성형하게 되는 경우에는 이중관에 비하여 원료의 사용량이 크게 향상되므로 자연스럽게 강도가 향상되는 현상이 발생하지만, 원료의 소모량에 비하여 강도가 정비례하게 향상되지 못하는 결점이 있었다.However, when the three-layer pipe is formed, the strength of the raw material is greatly improved compared to the double pipe, so that the strength naturally occurs, but the strength is not directly proportional to the consumption of the raw material.

이와 같이 다양한 방법으로 디씨 파이프의 강도를 향상시킬 수 있는 방안을 모색하였지만 기대에 부응하지 못하는 것이 현실이다.In this way, various ways have been found to improve the strength of the DC pipe, but the reality is that it does not meet expectations.

따라서 본 발명은 이러한 종래의 결점을 해소하기 위하여 안출된 것으로, 디씨 파이프의 돌출부 내부에 형성되는 공간부에 원주방향을 따라서 같은 간격으로 다수개의 공간 보강대를 형성하여 강도를 크게 향상시킬 수 있도록 하는 디씨 파이프 성형장치를 제공함을 목적으로 한다.Therefore, the present invention has been made to solve the above-mentioned drawbacks, DC to form a plurality of space reinforcement at the same interval along the circumferential direction in the space formed inside the protrusion of the DC pipe to significantly improve the strength It is an object to provide a pipe forming apparatus.
