본 발명은 스크류형 힘살이 형성된 합성수지 다층관 및 그 압출 성형방법과 장치에 관한 것으로서 더욱 상세히는 다수개의 힘살이 형성되고 통공을 가지는 합성수지관의 재료투입대비 강도 증강은 물론, 보온력 강화와 우수한 소음 방지 기능을 가진 스크류형 힘살이 형성된 합성수지 다층관 및 그 압출 성형방법과 장치에 관한 것이다.The present invention relates to a multi-layered synthetic resin tube formed by screw-type thread, and an extrusion molding method and apparatus, and more particularly, to increase the strength compared to the material input of a synthetic resin tube having a plurality of force is formed and having a hole, as well as strengthening the thermal insulation and excellent noise prevention The present invention relates to a multi-layered synthetic resin tube formed with a screw-shaped force rib having a function, and an extrusion molding method and apparatus thereof.
일반적으로 사용되고 있는 합성수지 다층관은 합성수지의 재료를 이용해 하수관, 배수관 전기, 통신 선로 등의 용도로 압출 성형되어지는 합성수지 원형관 중 소음억제 및 휨강도, 보온력 등을 증강하기 위해 그 관의 살 두께 속에 일층이상의 통공을 더 형성시킨 것을 의미한다.Synthetic resin multilayer pipes generally used are one layer in the thickness of the flesh to increase noise suppression, flexural strength, and heat retention among synthetic resin round pipes that are extruded for use in sewage pipes, drain pipes, and communication lines. It means that the above-mentioned through hole was further formed.
그리고 그 제조방법으로서는 통상 연질인 PE 재질을 이용하여 먼저 소형 사각관으로 길게 압출한 다음 소정의 직경 나선형으로 감으면서 때워 큰 원통형이 되게 만들고, 그 외측에 또 다시 같은 방법으로 1층, 2층 ..... 더 감아 때움으로서, 원하는 형상의 합성수지 다층관으로 생산하는 것이 일반적이다.And as a manufacturing method, it is usually extruded into a small square tube first using a soft PE material, and then wound in a spiral with a predetermined diameter to make a large cylinder. .... By further winding, it is common to produce a synthetic resin multilayer tube of a desired shape.
이러한 종래 합성수지 다층관 제조방법은 합성수지 다층관을 생산하는 데 다수회의 생산공정 및 많은 재료투입이 불가피 함에 따라서 생산성이 저하되는 문제점이 있었을 뿐만 아니라, 코일 형태로 감으면서 때운 접합부마다 울퉁불퉁한 현상이 발생됨으로 외관상 좋지 않을 뿐만 아니라 장시간 사용시 그 접합부에 크랙이 발생하여 기밀성이 유지되지 못해 누수의 원인이 의기도 하는 등의 문제점이 있었다.Such a conventional method for manufacturing a multi-layered plastic tube has a problem that productivity is lowered due to the inevitable production process and a large number of material inputs to produce a multi-layered plastic tube, and a bumpy phenomenon occurs at every joint portion wound in a coil form. Not only does it look bad, but there is a problem such as the cause of leakage due to cracks are not maintained due to cracks at the junction when used for a long time.
이에 본 발명에서는 상기와 같은 종래의 문제점을 일소키 위하여 안출한 것으로서, 코일형태로 여러 겹 감아 제조하는 종래와는 달리 한번의 압출공정으로 신속히 생산가능 함은 물론 적은 재료 및 원가로 보다 매끈하고 강도를 증강시킨 합성수지 디층관을 생산할 수 있도록 한 것에 주안점을 두고 그 기술적 과제로서 완성한 것이다.Therefore, in the present invention, to solve the above-mentioned conventional problems, it is possible to produce quickly in one extrusion process, as well as to produce a plurality of layers in the form of coils, as well as more smooth and strength with less material and cost With the main focus on being able to produce synthetic resin laminated pipes with increased strength, the technical task was completed.
위 기술적 과제를 달성하기 위하여 본원에서는 첨부된 각 도면에 의거 보다 상세히 설명하면 하기와 같다.In order to achieve the above technical problem, the present invention will be described in more detail based on the accompanying drawings.

In forming and manufacturing a screw-type force synthetic resin multi-layered tube, which is surely compensated for the disadvantages of the force formed only in a straight direction,
압출기(10)를 통하여 이동되면서 다이스(20) 끝단에서 토출된 용융 합성수지 재료가 회전성형부재(40)를 통과시킬 때,When the molten synthetic resin material discharged from the end of the die 20 while passing through the extruder 10 passes through the rotomolding member 40,
그 회전성형부재(40)를 필요한 방향과 일정한 속도로 강제 회전시켜 후방으로 압출되는 힘살이 스크류형으로 연속 반복 형성되도록 한 것이다.The rotational molding member 40 is forcibly rotated in a required direction and at a constant speed so that the force extruding backwards is continuously formed in a screw type.
그 장치로서는,As the device,
수지재료 특히, 합성수지 재료를 융융한 후 그 용융 재료를 다이스(20) 양측으로 공급하는 압출기(10)와;An extruder 10 for melting a resin material, in particular a synthetic resin material, and then supplying the molten material to both sides of the die 20;
그 다이스(20) 내측에 상기 압출기(10)에서 공급된 용융재료를 스크류형 힘살(110) 모양으로 압출 되게 하기 위해 강제회전 되는 회전성형부재(40)를 구비시키되,The die 20 is provided with a rotational molding member 40 forcibly rotated to extrude the molten material supplied from the extruder 10 in the form of a screw type force meat 110,
상기 회전성형부재(40)의 외측에는 관의 외벽면을 잡아주는 외경 사이징(30)을 구비시키는 한편,On the outside of the rotomolding member 40 is provided with an outer diameter sizing 30 to hold the outer wall surface of the tube,
상기 회전성형부재(40)의 내측에는 관의 내벽면을 잡아주는 내경 사이징(50)을 설치하여서 된 것이다.Inside the rotational molding member 40 is to install an inner diameter sizing 50 to hold the inner wall surface of the tube.
상기한 구성 중 회전성형부재(40)는 관의 살 두께 속에 일층 이상의 통공(120)이 형성될 수 있도록 선택된 통공 형상에 따른 스크류형 힘살 형성부(44)와 다수개의 성형돌부(42)가 각각 형성된 토출부(41)와, 상기 토출부(41)와 나선결합이 되어 조임고정이 되는 홀더(44)로 구성되는 한편, 상기 성형돌부(42)의 내부에는 냉각용 에어홈(43)이 관통되어 후측 성형돌부(42), 에서 선측으로 소정압력의 에어가 분사되도록 한다.In the above-described configuration, the rotational molding member 40 has a screw type force forming part 44 and a plurality of forming protrusions 42 according to the shape of the through hole selected so that one or more through holes 120 can be formed in the thickness of the tube. The discharge part 41 is formed, and the holder 44 is helically coupled to the discharge part 41 to be tightened and fastened, while the cooling air groove 43 penetrates inside the molding protrusion 42. Then, the air of a predetermined pressure is injected from the rear forming protrusion 42 to the ship side.
그리고 상기 회전성형부재(40)의 외측에 설치되는 외경 사이징(30)은 도시된 바와 같이 이동되는 합성수지 다층관 성형물이 이동될 때 그 관의 외측벽면을 받쳐 주면서 진공/흡입으로 잡아당겨 관의 외면형태를 변형 없이 매끄럽고 완벽하게 유지될 수 있도록 에어흡입구(31)와 에어순환로(34)가 다수개 형성함과 동시에 냉각을 위하여 냉각수 주입구(32)와 냉각수로(33)이 각각 구성되고, 교체 혹은 고장시 분해 조립 또한 용이하도록 착탈 가능토록 한다.And the outer diameter sizing 30 installed on the outer side of the rotational molding member 40 is pulled by the vacuum / suction while supporting the outer wall surface of the pipe when the synthetic resin multilayer pipe molding is moved as shown, the outer surface of the tube Cooling water inlet 32 and the cooling water passage 33 are configured for cooling and at the same time a plurality of air inlet 31 and air circulation path 34 is formed so that the shape can be maintained smoothly and completely without deformation, replace or In case of failure, disassembly and assembly are also possible.
한편, 상기 내경 사이징(50)은 합성수지 다층관의 내측벽면을 받쳐주는 가운데 내향으로 진공흡입이 가능토록 다수개의 에어 흡입구(51)가 형성됨과 동시에 냉각수 순환용 냉각수 인입구 및 배수구(52)가 각각 마련된다.On the other hand, the inner diameter sizing 50 is provided with a plurality of air inlets 51 to support the inner wall surface of the synthetic resin multilayer tube inwards to allow vacuum suction inward and at the same time the cooling water inlet and the drain 52 for the cooling water circulation is provided. do.
아울러 상기 내경 사이징(50)의 후측에는 전, 후 일정폭 작동이 가능한 에어실린더 작동로드(53)가 축 연결되어 있음에 따라서 압출이 시작된 이후에 전진하여 합성수지 다층관의 내측면을 잡아줄 수 있고, 이는 보다 원활한 압출성형에 크게 기여한다.In addition, since the rear side of the inner diameter sizing 50 is connected to the air cylinder operating rod 53 capable of operating a predetermined width before and after the shaft, it can be advanced after the extrusion starts to hold the inner surface of the multilayered plastic pipe. This contributes greatly to smoother extrusion.
이와 같이 탈착이 용이한 회전성형부재(40)로 인해 수지관의 두께속에 일층 이상의 통공(120)을 일체화 형성할 수 있고, 그 통공(120)의 형태 또한 다양하게 선택할 수 있으며, 나아가 상기 내경 사이징(50)으로 인해 합성수지 다층관의 내, 외측면 모두 완벽하고도 매끈하게 압출 성형할 수 있다.In this way, the easy-detachable rotational molding member 40 can be integrally formed in one or more layers of the through-hole 120 in the thickness of the resin tube, the shape of the through-hole 120 can also be variously selected, furthermore, the inner diameter sizing Due to the 50, both the inner and outer surfaces of the synthetic resin multilayer tube can be extruded perfectly and smoothly.
그리고 무엇 보다 중요한 것은 상기 회전성형부재(40)를 강제 회전시킴으로서 스크류형힘살(110)이 형성되는 바 이는 회전성형부재(40)의 회전 속도에 따라 힘살(110)의 간격이 넓어질 수도 있고 좁아질 수도 있는데 이는 합성수지 다층관(100)의 사용용도와 목적에 맞게 다양하게 선택성형이 가능한 것이다.한편, 상기와 같이 구성된 압출 성형장치를 이용하여 성형된 다층관은 다층관 및 힘살이 일체로 압출되어 이음매 없이 일체로 형성되고, 상기 힘살(110)이 다수개가 다층관의 원주방향에 대하여 상호 등간격을 유지함과 동시에 다층관의 길이방향에 대하여 스크류형으로 연속되도록 형성되며. 상기 통공(120)은 다층관의 일측에서 타측까지 폐쇠됨이 없이 연속으로 형성되게 된다.And most importantly, the screw shaped force 110 is formed by forcibly rotating the rotomolding member 40, which may be wider or narrower depending on the rotational speed of the rotatable member 40. This can be variously molded according to the purpose and purpose of use of the synthetic resin multilayer tube 100. Meanwhile, the multilayer tube formed by using the extrusion apparatus configured as described above is integrally extruded with a multilayer tube and a force. It is formed integrally without a seam, the plurality of force meat 110 is formed so as to be continuous in a screw-like shape with respect to the longitudinal direction of the multilayer tube while maintaining the equal intervals with respect to the circumferential direction of the multilayer tube. The through hole 120 is formed continuously without being closed from one side to the other side of the multilayer pipe.
아울러 상기 회전성형부재(40)는 조립이 용이하도록 구성한 바, 도 7에서 도시된 바와 같이 회전성형부재(40)의 토출부(41)만 교체해주면 좀더 다양한 형상의 스크류형힘살이(110) 형성된 합성수지 다층관을 성형할 수 있을 뿐만 아니라 어떠한 방향으로 단면을 자르더라도 힘살(110)이 형성되어지기 때문에 강성이 우수한 합성수지 다층관을 수월하게 성형할 수 있는 것이다.In addition, the rotational molding member 40 is configured to facilitate assembly, and as shown in FIG. 7, if only the discharge part 41 of the rotational molding member 40 is replaced, the screw-shaped teeth 110 having various shapes are formed. Not only can the synthetic resin multilayer tube be formed, but the force rib 110 is formed even when the cross section is cut in any direction, so that the synthetic resin multilayer tube can be easily formed with excellent rigidity.
또한 강제회전이 되게 하기 위해서는 구동모터(미도시)와의 벨트(미도시)연결 내지는 체인(미도시)연결 등으로 가능한 것이며, 중요한 것은 성형부재(40) 전체를 일정속도로 회전 시켜준다는 것이다.In addition, in order to be forced rotation is possible by the belt (not shown) connection or the chain (not shown) connection with the drive motor (not shown), it is important to rotate the entire molding member 40 at a constant speed.
이상과 같이 본 발명의 스크류형 힘살이 형성된 합성수지 다층관의 압출 성형방법 및 장치는 일일이 나선 형태로 감음과 동시에 때움 생산하였던 종래 방법과는 달리 합성수지 다층관을 일체화 성형할 수 있음은 물론 합성수지 다층관의 내, 외측면 모두 매끈하고 확실한 그 형태를 유지함과 동시에 내, 외측면과 일체형으로 스크류형 힘살이 형성됨으로서, 보다 적은 원가로 보다 우수한 품질의 합성수지 다층관을 제공받을 수 있는 등 합성수지 다층관 압출 성형에 획기적인 방안이 될 수 있는 등 그 기대되는 바가 실로 다대한 발명이다.As described above, the extrusion molding method and apparatus for the multi-layered synthetic resin tube formed with the screw-shaped force of the present invention can be integrally molded with the synthetic resin multi-layer tube, unlike the conventional method, which is wound and produced at the same time. Multi-layer extrusion of synthetic resin such that the inner and outer surfaces of the inner and outer surfaces maintain a smooth and reliable shape, and at the same time, the screw-shaped force is formed integrally with the inner and outer surfaces, so that a higher quality synthetic multilayer pipe can be provided at a lower cost. Indeed, it is a great invention as it can be a breakthrough in molding.
