Description
본발명은 각종의 배관재로 사용되는 합성수지관을 성형하여 주기 위한 것으로, 특히 겔상태로 공급되는 합성수지를 확실하게 진공흡착하여 주면서도 신속하게 냉각시켜 주어서 합성수지관의 품질 및 생산성을 향상시켜 주는 합성수지관 성형용 사이징에 관한 것이다.The present invention is for molding synthetic resin pipes used for various piping materials, and in particular, synthetic resin pipes are formed to improve the quality and productivity of synthetic resin pipes by cooling them quickly and reliably by vacuum suction. It is about dragon sizing.
이전부터 통수관이나 배선관과 같은 배관재로서 합성수지관이 제공되어서 유용하게 사용되어 왔으며, 이러한 합성수지관을 제조하기 위하여 다양한 구조와 형태의 합성수지관 제조장치들이 개발되어 있다.In the past, synthetic resin pipes have been used as piping materials such as water pipes and wiring pipes, and have been usefully used, and synthetic resin pipe manufacturing apparatuses of various structures and shapes have been developed to manufacture such synthetic resin pipes.
이와 같은 합성수지관 제조장치 중에 하나는 합성수지 원재료를 용융시켜 주며 용융된 겔상태의 합성수지를 공급하여 주는 노즐을 가지는 합성수지공급부와, 상기 합성수지공급부의 후방에 배치되어서 노즐로부터 공급되는 겔상태의 합성수지를 진공흡착시키고 냉각시켜서 합성수지관으로 성형하여 주도록 냉각수가 채워진진공박스 내에 사이징을 설치하여서 된 합성수지관성형부와, 상기 합성수지관성형부의 후방에 합성수지관이 통과하여서 경화되도록 일렬로 설치되는 수개의 냉각수통들을 가지는 합성수지냉각부로 합성수지관을 연속적으로 압출성형하여서 제조하여 주도록 구성되었다.One of the synthetic resin tube manufacturing apparatus is a synthetic resin supply unit having a nozzle for melting the raw material of synthetic resin and supplying the synthetic resin in the molten gel state, and the synthetic resin in the gel state is disposed behind the synthetic resin supply unit and supplied from the nozzle Synthetic resin tube molding part formed by sizing in a vacuum box filled with cooling water for adsorption, cooling, and molding into a synthetic resin tube, and several cooling water tanks installed in a row so that the synthetic resin pipe passes through the plastic resin tube molding part. Synthetic resin cooling unit was configured to produce by continuously extruding the synthetic resin tube.
이와 같은 합성수지관 제조장치에 있어, 겔상태로 공급되는 합성수지를 합성수지관으로 성형하여 주는 사이징은 반드시 냉각을 겸한 진공박스 내부에 설치되어서 간접적인 진공흡착력과 냉각력에 의존하게 되므로, 합성수지관의 품질 및 생산성이 크게 저하되는 결과를 초래하게 되었다.In the synthetic resin tube manufacturing apparatus, the sizing for forming the synthetic resin supplied in the gel state into the synthetic resin tube is necessarily installed inside the vacuum box that serves as cooling, so it depends on the indirect vacuum adsorption and cooling power, and thus the quality of the synthetic resin tube And resulted in a significant drop in productivity.
즉, 종래의 합성수지관 성형용 사이징은 독자적으로 냉각기능과 진공흡착기능을 갖추고 있지 못하였기 때문에, 냉각수가 채워진 진공박스 내부에 설치하여 그 진공박스 내부를 진공시키면 합성수지가 진공흡착되어서 합성수지관으로 성형될 수 있게 하여 주므로, 합성수지에 대하여 진공흡착력이 매우 미약하게 발휘되어서 합성수지관의 성형시에 불량률이 증가될 뿐만 아니라, 균일한 품질의 합성수지관을 성형하여 주기에 역부족한 문제점이 있었다.That is, the conventional synthetic resin tube molding sizing did not have a cooling function and a vacuum adsorption function independently, so if the inside of the vacuum box filled with cooling water and vacuum the inside of the vacuum box, the synthetic resin is vacuum-adsorbed and molded into the synthetic resin tube. Since the vacuum adsorption force is very weakly exerted on the synthetic resin, the defect rate is increased when the synthetic resin tube is molded, and there is a problem in that the synthetic resin tube of uniform quality is inadequate in the cycle.
더욱이, 사이징을 통과한 합성수지관이 진공박스 내에 채워진 냉각수와 자연적으로 접촉하여서 냉각되도록 하기 때문에, 합성수지관이 냉각수와 접촉하는 냉각시간이 매우 짧은 단점이 있음을 감안하여 볼 때, 합성수지관에 적정한 냉각시간을 부여하기 위한 조치로서 작업속도를 늦추면 생산성이 크게 저하되고, 냉각수통의 개수를 늘리는 조치를 취하면 합성수지관 성형장치가 대형화되는 문제점을 수반하게 되었다.Furthermore, since the synthetic resin tube passing through the sizing is allowed to cool in natural contact with the cooling water filled in the vacuum box, the cooling time that the synthetic resin tube contacts with the cooling water is very short. As a measure for giving time, slowing down the work speed greatly reduced the productivity, and taking measures to increase the number of cooling water tanks entailed the problem of increasing the size of the plastic pipe forming apparatus.
본발명의 목적은 공급되는 합성수지에 대하여 진공흡착력이 확실하게 발휘되도록 하여서, 우수한 품질의 합성수지관을 성형할 수 있게 하여 주는 합성수지관 성형용 사이징을 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a sizing for molding a synthetic resin tube which enables the vacuum adsorption force to be reliably exerted on the synthetic resin to be supplied, thereby enabling the molding of a superior quality synthetic resin tube.
본발명의 또 다른 목적은 공급되는 합성수지에 대하여 냉각력이 신속하게 발휘되도록 하여서, 합성수지관의 생산성을 극대화하여 주면서도 합성수지관 제조장치의 소형화를 꾀하여 주는 합성수지관 성형용 사이징을 제공하는 데 목적이 있다.Another object of the present invention is to provide a sizing for forming a synthetic resin pipe to maximize the productivity of the synthetic resin pipe by minimizing the production of the synthetic resin pipe while maximizing the productivity of the synthetic resin to be supplied quickly. .

다시말해서, 본발명의 합성수지관 성형용 사이징(100)은 도4의 도시와 같이,내부의 성형통로(11)를 향하여 수개의 냉각수분사구멍(12)들과 진공흡착구멍(13)들이 각각 1개조로 하여 교대로 뚫어지는 사이징관부(10)를 가지며, 상기 사이징관부 (10)의 외측에 양측의 고정부재(50)로 밀실하게 설치되는 분리관부(20)로서 냉각수분사구멍(12)들 및 진공흡착구멍(13)들이 분리되도록 하고, 상기 사이징관부(10)의 냉각수분사구멍(12)들 및 진공흡착구멍(13)들이 상기 분리관부(20)를 관통하여서 설치되는 냉각수공급관부(30)들 및 공기흡출관부(40)들과 각각 연통되도록 구성하여서, 상기 사이징관부(10) 내부의 성형통로(11)를 통과하는 합성수지(1a)에 대하여 진공흡착력과 냉각력을 확실하고 신속하게 발휘되도록 한 것이다.In other words, the synthetic resin tube molding sizing 100 of the present invention has a plurality of cooling water injection holes 12 and vacuum suction holes 13 toward the inner molding passage 11 as shown in FIG. Cooling water injection holes (12) having a sizing pipe (10) to be alternately drilled by alteration, and as a separation pipe (20) securely installed on both sides of the fixing member (50) on the outside of the sizing pipe (10) and Cooling water supply pipe portion 30 to allow the vacuum suction holes 13 are separated, the cooling water injection holes 12 and the vacuum suction holes 13 of the sizing pipe unit 10 is installed through the separation pipe unit 20. And the air suction pipes 40 are configured to communicate with each other, so that the vacuum adsorption force and the cooling force can be reliably and quickly exerted on the synthetic resin 1a passing through the molding passage 11 inside the sizing pipe part 10. It is.
따라서, 본발명은 첫째 사이징관부(10) 내부의 성형통로(11)를 따라 통과중인 합성수지(1a)를 그 성형통로 내면에 확실하게 진공흡착시켜서 합성수지관(1)으로 성형하여 주기 때문에, 합성수지관 성형시에 불량률을 감소시켜 주면서도 균일한 품질의 합성수지관을 성형할 수 있게 하여 주며, 둘째 사이징관부(10) 내부의 성형통로(11)를 따라 통과중인 합성수지(1a)에 대하여 새로운 냉각수를 반복적으로 분사하고 흡출시켜서 단위시간당 냉각수의 접촉시간을 대폭적으로 늘려주기 때문에, 성형작업을 빠르게 진행시킬 수 있도록 하여서 합성수지관의 생산량을 증대시켜 줄 뿐만 아니라, 불필요한 냉각수통을 감축시킬 수 있도록 하여서 합성수지관 제조장치의 설비비용을 절감하여 주는 장점을 가지게 되는 것이다.Therefore, in the present invention, the synthetic resin tube 1a is reliably vacuum-adsorbed to the inner surface of the molding passage by forming a synthetic resin tube 1 that is passing along the molding passage 11 inside the sizing tube section 10, thereby forming a synthetic resin tube.

도면중 미설명 부호 200은 합성수지공급부이고, 210은 노즐이다.In the drawings, reference numeral 200 denotes a synthetic resin supply unit, and 210 denotes a nozzle.
이하, 첨부도면에 도시되는 구체적인 실시예를 통하여 본발명의 기술내용을 상세히 설명하면 다음과 같다.Hereinafter, the technical details of the present invention through the specific embodiments shown in the accompanying drawings in detail as follows.
본발명의 실시예에서 사이징관부(10)는 원통형의 단면형상으로 내부에 길게 트여지는 성형통로(11)를 가지도록 형성하여서 되며, 그 외주면 둘레를 따라 간격을 두고 나선홈으로서 교대로 형성되는 냉각수라인(14)과 진공라인(15)으로 각각 연이어져서 성형통로(11)를 향하여 뚫어지는 냉각수분사구멍(12)들과 진공흡착구멍 (13)들을 형성하여서 된 것으로 예시하고 있다. 이러한 사이징관부(10)는 냉각수라인(14)을 경유하여 공급되는 냉각수가 냉각수분사구멍(12)들을 통하여 성형통로 (11)를 통과중인 합성수지(1a)에 분사되도록 하여서 냉각시키며, 진공흡착구멍(13)들로서 흡입된 냉각수와 함께 주변의 공기를 진공라인(15)을 경유하여 외부로 흡출되도록 하여서 성형통로(11) 내면에 합성수지(1a)를 진공흡착시키는 작용을 동시에 연속 반복적으로 수행하여서 합성수지관(1)을 성형할 수 있게 하여 주는 것이다.In the embodiment of the present invention, the sizing pipe part 10 is formed to have a forming passage 11 that is elongated in a cylindrical cross-sectional shape, the cooling water alternately formed as a spiral groove at intervals along the outer circumferential surface The cooling water injection holes 12 and the vacuum suction holes 13 which are connected to the line 14 and the vacuum line 15 and drilled toward the molding passage 11 are illustrated. The sizing pipe unit 10 cools the cooling water supplied via the cooling water line 14 to be injected into the synthetic resin 1a passing through the molding passage 11 through the cooling water injection holes 12, and is cooled by a vacuum suction hole ( 13) by allowing the surrounding air to be sucked to the outside via the vacuum line 15 together with the sucked cooling water to perform vacuum adsorption of the synthetic resin 1a on the inner surface of the molding passage 11 simultaneously and repeatedly. It makes it possible to shape (1).
그리고, 상기 사이징관부(10)의 성형통로(11) 내주면 둘레에 진공흡착구멍 (13)들이 연이어지도록 나선형으로 진공흡착홈(16)을 형성함이 중요하다. 그 이유는, 상기 진공흡착구멍(13)들의 진공흡착력이 합성수지(1a)에 대하여 균일하게 작용될 수 있도록 하여 주면서도, 상기 냉각수분사구멍(12)들로부터 분사된 냉각수가 합성수지(1a) 외면에 펼쳐져서 골고루 접촉한 후에 흡입 회수되도록 하여서 냉각능력을 향상시켜 주도록 하기 위함이다.In addition, it is important to form a vacuum suction groove 16 helically so that the vacuum suction holes 13 are connected around the inner circumferential surface of the forming passage 11 of the sizing pipe part 10. The reason is that the vacuum suction force of the vacuum suction holes 13 can be uniformly applied to the synthetic resin 1a, while the coolant sprayed from the cooling water injection holes 12 is spread on the outer surface of the synthetic resin 1a. This is to improve the cooling capacity by allowing the suction to be recovered after being evenly contacted.
또한, 상기 사이징관부(10)에는 그 외면의 냉각수라인(14)과 진공라인(15) 사이에 나선형으로 형성된 끼움홈(17) 내에 기밀패킹(18)을 삽입 설치하여서, 상기 사이징관부(10)의 외면에 끼워지는 분리관부(20)로서 냉각수분사구멍(12)들과 진공흡착구멍(13)들을 구획하여서 분리시키는 데 도움이 되도록 한다.In addition, the sizing pipe part 10 is installed in the sizing pipe part 10 by inserting an airtight packing 18 into a helical fitting groove 17 formed between the cooling water line 14 and the vacuum line 15 on the outer surface thereof. Separation tube portion 20 to be fitted to the outer surface of the cooling water injection holes 12 and the vacuum suction holes 13 to help to separate.
또한, 상기 사이징관부(10) 양측의 끝단부 외면에는 암나사부(19)를 형성하여서, 상기 양측의 고정부재(50)들이 나사결합되어서 조립되도록 한다.In addition, the female screw portion 19 is formed on the outer surface of the end of both sides of the sizing pipe portion 10 so that the fixing members 50 of both sides are screwed together.
여기에서, 상기 사이징관부(10)는 도5의 변형예에서와 같이, 내부에 길게 트여지는 성형통로(11)를 가지며 그 성형통로의 길이방향 등간격마다 환상홈으로서 교대로 형성되는 냉각수라인(14)과 진공라인(15)으로 각각 연이어져서 성형통로 (11)를 향하여 뚫어지는 냉각수분사구멍(12)들과 진공흡착구멍(13)들을 형성하여서 될 수도 있음을 밝혀 둔다.Here, the sizing pipe section 10 has a forming passage 11 that is elongated therein, as in the modification of Fig. 5, and the cooling water line alternately formed as an annular groove at every equal longitudinal interval of the forming passage ( 14) and the vacuum line 15 may be formed by forming the cooling water injection holes 12 and the vacuum suction holes 13 which are opened to the molding passage 11, respectively.
분리관부(20)는 상기 사이징관부(10)의 끼움홈(17)에 삽입 설치된 기밀패킹 (18)과 밀실하게 맞닿아지도록 설치하여서, 상기 사이징관부(10)의 진공라인(15)과 냉각수라인(14)을 구획하여 주므로, 그 진공라인(15)으로 연이어지는 진공흡착구멍 (13)들과, 냉각수라인(14)으로 연이어지는 냉각수분사구멍(12)들을 분리시켜 주게 되는 것이다. 이와 같이 분리관부(20)는 상기 사이징관부(10)의 냉각수분사구멍 (12)들과 진공흡착구멍(13)들을 분리시켜 주어서, 그 냉각수분사구멍(12)들은 냉각수를 분사하고 진공흡착구멍(13)들은 분사된 냉각수와 공기를 동시에 흡입하는 작용을 원할하게 수행할 수 있게 하여 주는 것이다.Separating pipe portion 20 is installed so as to closely contact with the airtight packing 18 is inserted into the fitting groove 17 of the sizing pipe portion 10, the vacuum line 15 and the cooling water line of the sizing pipe portion 10 Since 14 is divided, the vacuum suction holes 13 connected to the vacuum line 15 and the cooling water injection holes 12 connected to the cooling water line 14 are separated.
