본 고안은 압출기에서 압출되는 수지액이 맨드렐의 굴곡부를 통과하면서 진공압으로 이를 흡인하여 굴곡상태의 나사형 코러게이트(corrugate)관으로 밀착되어 권회 압출되도록 하는 통상의 나사형 수지관을 성형하는 맨드렐에 있어서 맨드렐의 내부에서 별도의 연질 또는 경질의 수지액을 압출시켜 굴곡상태의 나사형 권회 코러게이트관의 내벽면에 열 융착되어 나사형 권회 코러게이트관의 내벽이 단일체로 성형되면서 중공부가 형성되도록 하는 단일체의 내벽으로 중공부를 형성시킨 나사형 권회 코러게이트관의 성형 장치에 관한 것으로 단순구조에 의하여 간편하고 용이한 능률적인 제작하므로서 제작비의 절감에 따라 저렴하게 공급할 수 있게 하며 내벽을 연질 또는 경질의 수지액을 필요에 따라 주입하여 단일체로 용융 성형되게 하므로서 사용 용도에 따라 유연성과 견고성의 제품을 선택적으로 성형 제작할 수 있도록 함에 주안점을 둔 것이다.The present invention is to form a conventional screw-type resin tube that the resin liquid extruded from the extruder is sucked by the vacuum pressure while passing through the bent portion of the mandrel close to the bent screw corrugate tube to be wound extruded In the mandrel, a separate soft or hard resin solution is extruded from the inside of the mandrel and heat-sealed to the inner wall surface of the bent screw wound corrugated pipe to form a hollow as the inner wall of the screw wound corrugated pipe is formed into a single body. The present invention relates to a device for forming a screw-type wound corrugated tube in which a hollow part is formed by an inner wall of a unit to allow an additional part to be formed. The simple structure allows simple and easy and efficient manufacturing to be supplied at a low cost, and the inner wall is soft. Alternatively, it is used by injecting a hard resin liquid as necessary to melt molding into a single body. The main focus is on the selective molding of flexible and robust products according to the application.
종래의 나사형 권회 코러게이트관을 성형하는 캇타 필터식에 있어서는 압출기의 성형 헤드에서 중공부가 형성된 ""모양을 갖춘 띠형의 나사선 형태로서 연속적으로 성형되어 나온 상태에서 별도의 연접장치에 의하여 나사형 권회 코러게이트관을 제작하였으므로 제작금형 및 장치구조가 복잡하여 경제성이 적은 결점이 있었다.In the conventional filter type for forming a threaded wound corrugated pipe, a hollow portion is formed at a molding head of an extruder. "A thread-shaped wound corrugated tube was manufactured by a separate splicing device in the form of a strip-shaped threaded line with a continuous shape, and thus, the manufacturing mold and the device structure were complicated, resulting in a low economic feasibility.
본 고안은 상기와 같은 종래의 결점을 해결하고 단순 구조에 의하여 보다 간편하고 용이하게 제작할 수 있게 하며 사용용도에 따라 유연성과 견고성의 제품을 선택적으로 성형 제작할 수 있도록 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves the above-mentioned drawbacks and enables simpler and easier production by simple structure, and enables the selective molding of products with flexibility and robustness according to the intended use. The explanation is as follows.
다이스와 연설되어 나사형 굴곡부(1a)가 형성된 맨드렐(1)의 중앙부로부터 냉각공기송풍로(2)와 내벽면(3a)을 형성하는 압출통로(3) 및 굴곡면(4a)을 형성하는 압출통로(4)를 형성하며, 통상의 굴곡부(1a)의 둘레에 체인기어(5)를 결착시킨 회전체(6)의 둘레에는 진공 흡입구(7)와 냉각수 순환구(8)를 설한 통상의 장치인 지지체(9)를 베어링(10)과 오일패킹(11)으로 접설시켰으며 냉각 송풍로(2)의 선단에는 둘레에 다수의 송풍구멍(12)을 뚫은 지지대(13)를 결착하여 내벽면(3a)을 지지하는 내열성 고무원반(14)을 착설하여서 된 것이다.The extrusion passage 3 and the curved surface 4a forming the cooling air blower 2 and the inner wall surface 3a are formed from the center of the mandrel 1 having the screw-shaped curved portion 1a formed thereon. An extrusion passage 4 is formed, and a vacuum suction port 7 and a cooling water circulation port 8 are provided around the rotator 6 in which the chain gear 5 is fixed around the usual curved portion 1a. The support body 9, which is a device, is connected to the bearing 10 and the oil packing 11, and at the tip of the cooling blower 2, a support 13 having a plurality of blower holes 12 is circumferentially attached to the inner wall surface. It was made by laying the heat resistant rubber disk 14 which supports (3a).
도면중 미설명 부호 15는 본 고안의 장치에 의하여 성형된 나사형 권회 코러게이트, 16은 중공부, 17은 공기구멍을 표시한 것이다.In the figure, reference numeral 15 denotes a threaded winding corrugated body formed by the apparatus of the present invention, 16 denotes a hollow portion, and 17 denotes an air hole.
이와같이 구성된 본 고안 장치의 작용효과를 설명하면 다음과 같다.Referring to the operation and effect of the device of the present invention configured as described above are as follows.
압출기에서 압출되는 수지액이 다이스와 연설되어 형성시킨 맨드렐(1)의 압출통로(4)(3)를 통하여 압출하게 되는데 외측의 압출통로(4)를 통하여 압출되는 수지액은 맨드렐(1)의 굴곡부(1a)로 압출되면서 ""형의 굴곡면(4a)를 형성하게 되고 내측의 압출통로(3)를 통하여 압출되는 수지액은 ""형의 굴곡면(4a)의 내면부로 압출되어 냉각공기 송풍로(2)에서 송풍되는 송풍력에 의하여 ""형의 굴곡면(4a)의 내면으로 열응착되어 내벽면(3a)을 형성하면서 중공부(16)를 형성하게 되는 것인데 이때 체인기어(5)에 의하여 회전되는 회전체(6)의 회전에 따라 외측의 압출통로(4)를 통하여 압출되는 수지액이 맨드렐(1)의 굴곡부(1a)와 회전체(6)가 접설되어 형성되어지고 있는 일정한 간격을 통하여 나사형으로 권회되면서 ""형의 굴곡면(4a)의 형태로서 압출하게 됨과 동시에 내측의 압출통로(3)를 통하여 압출되는 수지액이 지지대(13)선단부에 착설시킨 내열성 고무원반(14)의 둘레에 끼워물려 압출되는 상태로서 내열성 고무원반(14)의 내측인 내벽면(3a)이 내통부가 밀폐된 상태가 되므로 냉각 공기 송풍로(2)에서 송풍되는 송풍력은 지지대(13)의 둘레에 뚫은 송풍구멍(12)을 통하여 내벽면(3a)의 전체면에 강한 송풍압력을 가하게 되어 내측의 압출통로(3)를 통하여 압출되는 수지액이 아직 적정온도의 고열을 유지하고 있는 상태로서 ""형의 내면부에 강력하게 응착되면서 중공부(16)가 형성되는 코러게이트관(15)이 나사형으로 권회되어 압출되는 것이다.The resin liquid extruded from the extruder is extruded through the extrusion passages 4 and 3 of the mandrel 1 formed by extending the die and the resin liquid extruded through the outer extrusion passage 4 is the mandrel 1. Extrusion into the bend 1a of the " "The resin liquid which forms the curved surface 4a of the type | mold and is extruded through the extrusion channel 3 inside is" "By the blowing force extruded to the inner surface of the curved surface 4a of the type and blown in the cooling air blower 2" It is thermally bonded to the inner surface of the " -shaped bent surface 4a to form the inner wall surface 3a to form the hollow portion 16. At this time, the rotation of the rotating body 6 rotated by the chain gear 5 The resin liquid extruded through the extrusion passage 4 on the outside thereof is wound into a screw through a predetermined interval formed by bending the bent portion 1a of the mandrel 1 and the rotor 6. The resin liquid extruded through the inner extrusion passage 3 while being extruded in the form of " curved surface 4a " is sandwiched around the heat-resistant rubber disk 14 mounted on the front end of the support 13 and extruded. Since the inner wall surface 3a, which is the inner side of the heat-resistant rubber disk 14, is in a state where the inner cylinder is sealed, the blowing force blown by the cooling air blowing path 2 is the blowing hole 12 drilled around the support 13. A strong blowing pressure is applied to the entire surface of the inner wall surface 3a through the resin liquid extruded through the inner extrusion passage 3 to maintain a high temperature at a proper temperature. The corrugated pipe 15, in which the hollow portion 16 is formed while being strongly adhered to the inner surface portion of the mold, is wound and extruded.
이러한 상태에서 회전체(6)의 둘레에 접설시킨 지지체(9)에 설한 진공 흡입구(7)로는 통상의 장치인 진공흡입장치에 의하여 진공압을 흡인하여 줌과 동시에 냉각수 순환구(8)로는 냉각수를 순환시켜 주면서 본 고안의 나사형 권회 코러게이트관(15)이 냉각 성형되게 되는 것이다.In such a state, the vacuum suction port 7 provided on the support body 9 attached to the circumference of the rotating body 6 sucks vacuum pressure by a vacuum suction device, which is a conventional device, and at the same time, the cooling water circulating port 8 cools the cooling water. By circulating the screw-type wound corrugated tube 15 of the present invention is to be cold-molded.
이와같이 된 본 고안은 공지의 압출기에 의하여 압출시킨 수지액은 ""형의 굴곡면을 압출 성형시키며 굴곡면의 내면부에 응착되어 내벽면과 중공부를 형성하는 수지액은 연질성이나 경질성의 수지액을 제품의 사용용도에 따라 선택적으로 압출 성형할 수 있는 것이며 연질성의 수지액을 사용하여 얻어진 제품은 사용시에 구불림 작용이 원활하며 경질성 수지액을 사용하여 얻어진 제품은 견고성이 양호하며 내벽면이 매끄러운 양질의 제품을 얻을 수 있는 것이다.The present invention thus obtained is a resin solution extruded by a known extruder is " "The resin liquid which extrudes the curved surface of the shape and adheres to the inner surface of the curved surface to form the inner wall surface and the hollow portion can selectively extrude the soft or hard resin liquid according to the use of the product. The product obtained by using the resin solution of the resin has a smooth bending effect during use, and the product obtained by using the hard resin solution has good rigidity and a good product having a smooth inner wall surface.
또한 단순구조장치에 의하여 보다 간편하고 용이하게 능률적으로 제작할 수 있으므로 생산원가를 절감하여 저렴하게 공급할 수 있는 이점이 있는 것이다.In addition, since the simple structure device can be more easily and easily produced efficiently, there is an advantage that can be supplied at low cost by reducing the production cost.
