The present invention relates to a manufacturing apparatus for a spiral pipe for drainage pipes used for waste water pipes, sewage pipes, storm water pipes.

In general, the manufacturing apparatus of a spiral tube made of a synthetic resin has one side curved from a die assembled to an extruder, and the other side is fixed to a die, assembled into a spiral tube molding machine assembled with a molding roller, and extruded from the die by an extruded tube that rotates the forming roller of the molding machine. It has been used a manufacturing apparatus for manufacturing a spiral tube is formed while integrally fusion welding both side wall surface in which the hollow sphere of the tube is formed while rotating in a spiral winding.

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.

600m/m이상)으로 사용되는 경향이 많은데 본 발명의 제품에서는 제품의 규격에 따른 두께의 보강 등으로 중공구의 크기가 커지는 구조에서 집중하중에 의한 외토압으로 파손되는 위험으로 이에 대한 대안이 요구되어 왔다.In particular, in case of heavy rain due to heavy rain and rainy season, the usage standard of the drainage pipe spiral pipe is compared with the standard suitable for the conventional construction site.

600m / m or more), but in the product of the present invention, there is a risk of being damaged by external load due to concentrated load in the structure in which the size of the hollow sphere increases due to the reinforcement of the thickness according to the specification of the product. come.

The present invention provides a manufacturing apparatus for manufacturing a structure for reinforcing the upper, lower and both side walls of the hollow sphere in the conventional spiral tube by the improvement of the manufacturing process according to the structural change of the molding machine and the cooling pipe in the manufacturing apparatus of the spiral pipe for drainage pipe. It is to provide a manufacturing apparatus that can manufacture a high-strength, durable spiral tube in a large diameter.

The present invention is a spiral pipe manufacturing apparatus for drainage pipes manufactured by assembling in accordance with the extrusion port of the die while assembling the die and the cooling pipe of the extruder composed of a conventional manufacturing device linked to the forming roller assembled while a plurality of circular configuration in the molding machine. Reinforced the structure of the forming roller mainly used in the device and the structure of the cooling pipe to reinforce the structure of hollow spheres and both side walls, which are recognized as main parts in the spiral pipe, so as to reinforce the external pressure and the external pressure reinforcement of the hollow spheres. The invention will be described in detail based on the drawings as follows.

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 ').

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.

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.

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.

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 '.

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 '. While determining the pitch width, the fusion raw material is extruded from a separate auxiliary die 18.

The cooling pipe 13, which is a main part of the present invention, is assembled in the die 2 and passes through the straight portion and the curved portion, while the tube 4 passes, as shown in FIG. 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.

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.

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. The outer and the outer curved separation pipe (26 ') is produced separately from each other and then used to fix the straight portion and the curved portion integrally with each other fixed portion 24 to form a curved groove 6.
