Abstract

PURPOSE: A producing device for a synthetic resin spiral pipe is provided to produce the spiral pipe having smooth inner circumference through attaching a cylinder shaped tubular body to inner circumference of the spiral pipe. CONSTITUTION: Rollers(1) of a shaping unit(2) are independently rotated. Herein, a soft material is contacted to the rollers and the shaping unit from an extruding dice(D1). The material is transferred to a circumference direction by the rotating rollers while being shaped into spiral shape. Air pressure is applied to reinforcing protrusions by an air supply pipe to complete shaping of the protrusions. A sub extruding dice(D2) extrudes the material toward outer circumference of the shaping unit. Thus, the material is wound up around an outer circumference of the shaping unit. Then, the reinforcing protrusions are deposited on an upper surface of a tubular body.

합성수지나선관의 제조장치{A MANUFACTURING SYSTEM OF PLASTIC SCREW PIPE}Manufacturing apparatus of synthetic resin spiral pipe {A MANUFACTURING SYSTEM OF PLASTIC SCREW PIPE}

본 발명은 합성수지재의 나선관을 제조하기 위한 장치에 관한 것으로, 특히 나선형의 보강돌조로된 관체내면에 원통형의 관체가 부착되게 제조하므로서 내면이 매끈하고 고강도의 나선관을 제조할 수 있도록 한 합성수지 나선관의 제조장치에 관한 것이다.The present invention relates to a device for manufacturing a spiral tube of a synthetic resin material, in particular a synthetic resin spiral that allows the manufacture of a spiral tubular body attached to the inner surface of the tubular body made of spiral reinforcement, smooth and high strength spiral tube It relates to an apparatus for manufacturing a tube.

일반적으로, 땅에 매설하여 하수, 배수관의 용도로 이용하기 위한 합성수지재의 나선관이 토목공사시에 널리 사용되고 있으며, 이러한 나선관은 매설하였을경우 외부의 압력이나 충격에 변형되거나 파손되는 것을 방지하기 위하여,In general, spiral pipes made of synthetic resin materials are widely used in civil engineering works to be used for sewage and drainage pipes in land, and these spiral pipes are buried to prevent deformation or breakage due to external pressure or impact.

형의 단면형상으로된 보강돌조가 나선형으로 권취되도록 제조하는 것이다.Reinforcing protrusions having a cross-sectional shape of a mold are manufactured to be wound in a spiral shape.

상기 나선관을 제조하기 위한 종래의 장치는 내부에 동력장치인 모타와 전동장치인 기어등이 장치된 동력부와, 동력부에 의하여 각각 개별적으로 회동되는 로울러가 원통형으로 배열된 성형부와, 합성수지원재료가 압출되는 압출다이스로 구성한 것으로서, 압출다이스에서형으로 인출되는 원재료가 회동되는 다수의 로울러, 즉 성형부에 권취되면서 원통형으로 제조되어 단면형상이형으로 형성되는 것이다.Conventional apparatus for manufacturing the spiral tube is a power unit equipped with a motor and a motor gear and the like, a molded part in which the rollers rotated individually by the power unit is arranged in a cylindrical shape, synthetic resin, It is composed of extrusion dice in which raw materials are extruded. A plurality of rollers in which the raw material drawn out into the mold is rotated, that is, rolled up to the forming part and manufactured in a cylindrical shape, It is formed into a mold.

그러나, 상기한 종래의 장치는 제조된 나선관의 내면이 굴곡진 형태로 형성되기 때문에 하수, 배수관으로 사용시, 흐르는 물이 굴곡진 부위에 의하여 저항이 발생되므로 유속이 저하되는 원인이 될 뿐 아니라, 각종 이물질아니 찌꺼기 등이 굴곡진 부위에 퇴적되는 등의 문제가 제기되었다.However, the above-described conventional apparatus is formed because the inner surface of the manufactured spiral pipe is formed in a curved shape, when used as sewage and drainage pipes, the resistance is caused by the curved portion of the flowing water, which causes not only the flow rate to be lowered, Various foreign matters or debris were deposited on curved areas.

또한, 매설하여 사용시 나선형의 보강돌조만으로는 외부의 충격이나 하중에 약하므로 보강돌조의 외면에 별개의 보강층을 이중으로 형성하여야 되었으나, 종래 장치의 구조상 보강돌조의 외면에 보강층을 부착형성 할 수 밖에 없으므로, 관체의 내주면은 보강돌조의 굴곡부위가 그대로 노출되었다.In addition, since the spiral reinforcement alone is weak to external impact or load when buried, the separate reinforcement layer had to be doubled on the outer surface of the reinforcement stone. On the inner circumferential surface of the tube, the bent portion of the reinforcement was exposed.

본 발명은 상기한 문제를 해결하기 위하여 연구개발된 것으로서, 합성수지재의 나선관을 제조함에 있어 보강돌조로된 관체의 내주면에 원통형의 관체가 부착 형성되도록 하는데 그 기술적 과제가 있다.The present invention has been researched and developed in order to solve the above problems, there is a technical problem that the cylindrical tubular body is attached to the inner circumferential surface of the tubular body made of reinforcement in the manufacture of the spiral tube of the synthetic resin material.

본 발명의 다른 기술적 과제는 관체가 보강돌조와 원통형의 이중으로 적층형성되어 내구력이 향상될 뿐 아니라, 관체 내주면이 매끈한 상태로 유지되므로 유속의 흐름에 원활하게 이루어지고 이물질이 적층되는 것이 방지되는 나선관을 제조할 수 있도록 하는데 있다.Another technical problem of the present invention is that the tubular body is formed of a double stack of reinforcement protrusions and a cylindrical shape, and not only improves durability, but also maintains a smooth state of the inner circumferential surface of the pipe so that the flow is smoothly flowed and the foreign material is prevented from being stacked. To make a tube.
