본 발명은 토목공사 및 택지개발공사 등에서 지중 매설하여 하수도관, 배수로관용으로 사용하는 합성수지제 나선관의 제조장치에 관한 것이다The present invention relates to a manufacturing apparatus of a synthetic resin spiral pipe used for sewage pipes and drainage pipes by underground laying in civil engineering works and residential land development works.
일반적으로 합성수지제 나선관은 지중 매설하여 장기간 사용하는 경우 내구성 및 외토압 보강을 하여주어야 하는데, 종래의 제조장치에서 제조된 나선관(1)은 생산성 재고를 위하여 나선권회된 중공구의 폭을 넓게하여 주기 위하여 냉각파이프의 몸체 폭을 넓게 하여서 나선권회되는 핏치복을 넓혀 주는데, 이는 생산성 재고가 되지만 외토압 보강의 취약점이 노출되는 제품이 제조되는 것으로 이에 따른 제조장치는 압출기(22)에 조립된 다이스(25)에 고정하는 냉각파이프(16)를 성형기(20)에서 원통형 구조로 서로 조립되어 있는 성형롤러(27)의 외주면에 맞추어 조립하여 주되, 압출기(22)에 조립된 다이스(25)에서 압출된 압출튜브(26)를 성형기(20)에서 성형롤러(27)의 회전력에 의하여 나선권회 공정으로 일체화하여 제조되는 나선관(1)은 압출튜브(26)를 냉각파이프(16)로 성형되는 중공구(10)와 접착대 부위를 접착롤러(23)로 일체하여 접착부(8)를 각각 성형시켜 일체화하면서 나선권회하여 제조하여 왔다.이때 제조되는 나선관은 지중 매설하여 장기간 사용하기에는 중공구(10)의 보강구조가 지중 매설된 주위의 토지에서 가해지는 외토압 보강에 대하여 보강력이 낮아서 가볍고 실용성이 높은 합성수지제 나선관의 사용범위가 한정되는 문제점이 많았다In general, synthetic spiral tubes should be buried in the ground for long-term use, and should be reinforced for durability and external pressure. Spiral tubes (1) manufactured in the conventional manufacturing apparatus have a wider width of spiral wound hollow balls for productivity inventory. In order to increase the width of the body of the cooling pipe to expand the spiral wound pitch clothing, which is productive inventory, but the product is exposed to the weakness of the external pressure reinforcement, and thus the manufacturing apparatus is a die assembled in the extruder 22 The cooling pipes 16 fixed to the 25 are assembled in accordance with the outer circumferential surface of the forming roller 27 assembled together in a cylindrical structure in the molding machine 20, and extruded from the die 25 assembled in the extruder 22. The spiral tube 1 manufactured by integrating the extruded tube 26 into the spiral winding process by the rotational force of the forming roller 27 in the molding machine 20 cools the extruded tube 26. The hollow sphere 10 formed by the pipe 16 and the adhesive zone are integrally formed by the adhesive roller 23, and are formed by spiral winding while forming and integrating the adhesive portions 8, respectively. In order to use for a long time, there were many problems in that the use range of the synthetic resin spiral tube, which is light and practical, was limited due to the low reinforcement against external pressure reinforcement applied to the surrounding land where the reinforcement structure of the hollow sphere 10 was buried.
본 발명에서는 상기 지적되는 문제점 등을 해결하면서 외토압 보강 및 경제성과 실용성이 좋으면서 생산성이 양호한 나선관의 제조장치 제공을 위한 발명으로서 생산성을 높이기 위하여 나선권회 되는 핏치 폭을 넓혀 주는 냉각파이프의 제공과 이에 따른 외토압 저하에 대한 보강구조와 동시에 생산성 재고를 제공하는 중공구조를 성형하는 제조장치의 제공을 위한 것이다The present invention provides a cooling pipe for widening the pitch width that is spiral wound to increase productivity as an invention for resolving the above-mentioned problems and the like, and to provide a device for manufacturing a spiral tube with good productivity and good productivity while improving economic pressure and practicality. And to provide a manufacturing apparatus for forming a hollow structure that provides a productivity inventory and at the same time reinforcement structure against external pressure drop
