이때 제조되는 나선관은 냉각파이프에서 만곡부위가 직사각형으로 형성되는 냉각파이프를 사용하므로 도13에 도시된 바와 같이 중공구(7)의 양측벽면(12)을 나선권회로 일체로 융착하여 제조되어 제공되므로, 이의 제품을 지중 매설하여 장기간 사용하는 경우 집중하중이나 누수 등으로 지반이 연약해지는 경우 중공구(7)의 상,하측면이 나선권회 방향으로 파손되므로 장기간 사용이나 하중이 많이 작용하는 도로용이나 건축용 등에서 사용이 제약되는 현실이다.In this case, the manufactured spiral tube uses a cooling pipe in which a curved portion is formed in a rectangular shape in the cooling pipe, so that both side wall surfaces 12 of the hollow sphere 7 are fused together as a spiral winding circuit as shown in FIG. Therefore, when the product is buried in the ground for long-term use, if the ground becomes soft due to concentrated load or water leakage, the upper and lower sides of the hollow sphere 7 are damaged in the spiral winding direction. It is a reality that its use is restricted in building and construction.

특히 집중 호우 및 장마 등으로 폭우가 많이 내리는 경우를 대비하여 배수로 관용 나선관의 사용 규격이 종래의 사용되는 시공 현장에 적절한 규격에 비교하여 중,대형(

The invention will be described in detail based on the drawings as follows.

도1에 도시된 바와 같이 압출기(3)에 조립된 나선관용 성형기(1)에 있어서 1차 성형공정으로 다이스(2)에서 튜브(4)를 압출시켜 냉각파이프(13)의 안내에 따라 성형기(1)의 성형롤러(20')의 회전으로 나선권회로 성형되면서 형성된 중공구(7)의 양측벽면을 일체로 융착시켜 제조하는 나선관(16)의 제조장치에 있어서 중공구(7)의 양측벽면(12)에서 중앙부로 절곡시켜 지지대(17)로 일체시켜 상,하측의 중공구(7)(7')를 형성하되 중앙부에 지지대(17)로 보강하기 위하여 도2 내지 도4에 도시된 바와 같이 다이스(2)에 조립된 냉각파이프(13)의 구조에서 만곡부위에서 양측 벽면의 중간부에 절곡부(22)를 서서히 깊게 형성하면서 만곡부의 끝부위에 상,하측의 만곡분리관(26)(26')을 만곡분리대(6)로 분리하되 다이스(2)에서 압출되는 튜브(4)를 냉각파이프(13)의 만곡부위로 압출하면서 성형시켜서 만곡분리대(6)에 맞추어 양측방향에서 서로 튜브(4)를 융착롤러(9)(9')로 절곡시켜 주면서 지지대(17)로 일체시켜서 상,하측에 중공구(7)(7')를 형성하여 주면서 본 발명의 목적인 배수로관용 나선관(16)을 제조하는 발명이다.In the spiral tube molding machine 1 assembled to the extruder 3 as shown in FIG. 1, the tube 4 is extruded from the die 2 in the primary molding process and guided by the cooling pipe 13. Both sides of the hollow sphere 7 in the manufacturing apparatus of the spiral tube 16, which are manufactured by integrally fusion welding both side wall surfaces of the hollow sphere 7 formed while forming the spiral winding by the rotation of the forming roller 20 'of 1). 2 to 4 to be bent from the wall surface 12 to the center portion to be integrated into the support 17 to form the upper and lower hollow spheres 7 and 7 ', but to reinforce the support 17 to the center portion. As described above, in the structure of the cooling pipe 13 assembled to the die 2, the bent portion 22 is formed deeply in the middle of both wall surfaces at the curved portion, and the upper and lower curved separating tubes 26 are formed at the ends of the curved portion. Separating the 26 'from the curved separator 6 and pressing the tube 4 extruded from the die 2 into the curved portion of the cooling pipe 13. While forming and bending the tubes 4 to each other in the lateral direction in accordance with the curved separator 6 by fusion rollers 9 and 9 ', and integrating with the support 17 to form hollow balls 7 and 7 at the upper and lower sides. It is an invention for manufacturing the spiral pipe 16 for the drainage pipe which is the object of the present invention while forming ').

상기 설명되는 냉각파이프(13)의 구조는 다이스(2)에서 조립되어서 직선부와 만곡부로 형성되는데 만곡부에서 절곡부(22)를 형성하면서 만곡부의 끝부위에서 부터 만곡분리대(6)을 형성한다.The structure of the cooling pipe 13 described above is assembled from the die 2 to form a straight portion and a bent portion, which forms a bent portion 22 at the bent portion to form a curved separator 6 from the end of the bent portion.

이때 튜브(4)의 양측부위를 서로 융착롤러(9)(9')로 절곡시켜 융착으로 형성된 지지대(17)는 상,하측으로 형성된 만곡분리관(26)(26')을 통과하는 동안 도면에 미도시된 냉각수의 공급으로 냉각되어 상,하측의 중공구(7)(7')를 형성하여 준다.At this time, the support 17 formed by fusion by bending both sides of the tube 4 with each other by the fusion rollers 9 and 9 'is shown while passing through the curved separation pipes 26 and 26' formed up and down. Cooled by the supply of cooling water not shown in the upper and lower hollow spheres (7) (7 ') to form.

여기서 지지대(17)를 성형하는 융착롤러(9)(9')의 조립은 나선권회로 회전되는 튜브(4)를 서로 넓은 폭의 간격을 유지하면서 회전성형이 이루어 져야 되므로 이의 해결을 위해서는 성형기(1)의 성형롤러(20')를 중간지지판(27)으로 각각 전,후로 등분하여 주면서 성형롤러(20')를 조립하기 위한 전,후의 지지판(25)로 성형롤러(20')(23)를 다수개를 서로 원형 상태로 각각 분리하여 조립한다.Here, assembling of the fusion rollers 9 and 9 'for forming the support 17 requires rotational molding of the tubes 4 rotated in a spiral winding while maintaining a wide gap therebetween. Forming rollers 20 'and 23 are formed by supporting plates 25 before and after assembling the forming rollers 20' while dividing the forming rollers 20 'of the 1) into an intermediate support plate 27 before and after. Assemble a plurality of separate from each other in a circular state.

여가서 전측 성형롤러(20')는 만곡된 성형튜브(4)를 냉각파이프(13)의 만곡부의 끝부에서 형성되는 만곡분리대(6)에 맞추어 양측에서 튜브(4)를 절곡시켜 지지대(17)를 성형하면서 상,하측에 성형된 중공구(7)(7')의 양측벽면(12)을 서로 간격(14)를 형성하면서 나선권회로 성형되도록 후측 성형롤러(21)를 지지판(25)과의 조립 각도를 낮게 조정하여 주면 양측벽면(12)에 일정간격(21)을 형성하면서 나선권회로 성형되는데 여기서 별도의 보조 다이스(18)에서 융착 원료를 압출시켜 상,하측의 중공구(7)(7')에서 양측벽면(12) 사이의 간격(21)에 융착대(14)를 압출시킨다.In the leisure, the front side forming roller 20 'bends the tube 4 on both sides in accordance with the curved separator 6 formed at the end of the curved portion of the curved forming tube 4 at the support pipe 17. The rear forming rollers 21 and the back plate forming rollers 21 are formed to form a spiral winding while forming a space 14 between the two side wall surfaces 12 of the hollow spheres 7 and 7 'formed on the upper and lower sides. By adjusting the assembly angle of the lower side is formed in a spiral winding while forming a predetermined interval (21) on both sides of the wall surface 12, where a separate auxiliary die (18) by extruding the fusion raw material in the upper and lower hollow sphere (7) The fusion zone 14 is extruded at the interval 21 between the two side wall surfaces 12 at 7 '.

즉 상기 설명은 본 발명의 제조 장치에서 성형기(1)의 성형롤러(20)를 조립하는 지지판(25)와의 조립 각도에 따라 나선권회된 핏치 폭이 결정되므로 1차 공정으로 전측 성형롤러(21)은 나선권회된 튜브(4)에 융착롤러(9)(9')를 양측으로 조립시켜 절곡시켜 지지대(17)를 성형하기 위하여 지지판(21)과의 조립각도를 크게 조립하고, 2차 공정으로 후측 성형롤러(23)에서는 튜브(4)가 성형되어 상,하측의 중공구(7)(7')의 양측벽면(12) 사이에 융착대(14)를 삽설용 간격을 유지되도록 나선권회된 핏치 폭을 결정하면서 별도의 보조다이스(18)에서 융착 원료를 압출하여 준다.That is, the above description is because the pitch width of the spiral wound is determined according to the assembling angle with the support plate 25 for assembling the forming roller 20 of the molding machine 1 in the manufacturing apparatus of the present invention. In order to form the support 17 by assembling the fusion rollers 9 and 9 'to both sides of the spirally wound tube 4, the assembly angle with the support plate 21 is largely assembled, In the rear forming roller 23, the tube 4 is molded and spirally wound so as to maintain the spacing for inserting the fusion splicing 14 between the wall surfaces 12 of the upper and lower hollow balls 7 and 7 '.

The support 17 formed by fusion by bending the tube 4 on both sides of the fusion rollers 9 and 9 'passes through the upper and lower curved separation tubes 26 and 26' and the curved separator 6 at the same time. While forming the support 17 while integrally fusion welding both side wall surfaces 12 formed in the upper and lower hollow spheres 7 and 7 'while being cooled and molded while rotating in the spiral winding circuit.

이때 사용되는 융착롤러(9)(9')는 성형기(1)의 일측 몸체에 일정 간격을 두고 공지의 방법과 같이, 자유 회동 가능하도록 설치하여서, 다이스(2)에서 압출되는 튜브(4)를 양측으로 균일하게 만곡분리대(6)에서 절곡시켜 지지대(17)가 형성되도록 한다.In this case, the fusion rollers 9 and 9 'used are installed at one side of the molding machine 1 at a predetermined interval so as to be freely rotatable, as is known in the art, and thus the tube 4 extruded from the die 2 is formed. The support 17 is formed by bending the curved separator 6 uniformly to both sides.

또 본 발명의 요부인 냉각파이프(13)의 실시예로서는 도5(가)(나) 내지 도7에 도시된 바와 같이 냉각파이프(13)의 몸체로 구성되는 직선부와 내측 만곡분리관(26)과 외측 만곡분리관(26')을 서로 별도로 제작한 다음 만곡요홈대(6)를 형성되도록 직선부와 만곡부를 서로 일체로 고정부(24)로 고정시켜 주어 사용한다.In addition, as an embodiment of the cooling pipe 13, which is a main part of the present invention, as shown in Figs. 5 (a) to 7, the straight portion and the inner curved separation pipe 26 constituted by the body of the cooling pipe 13 are shown.
