Description
본발명은 직경이 100㎜ 이상되는 합성수지 상·하수관에 동일한 재질로 플렌지를 형성할수 있도록 한 장치에 관한것으로, 특히 1차 성형된 합성수지관의 양단부를 플렌지 금형을 구성하는 암·수 플렌지 형성용 토출헤드 금형의 삽입부에 각각 끼우고, 이동금형을 닫은 다음 합성수지를 용융 토출시킨후 냉각 분리시키면, 양단부에 각각 암·수 플렌지가 형성된 합성수지관을 얻을수 있도록 하기 위한 것이다.The present invention relates to a device for forming a flange of the same material on the synthetic resin upper and sewer pipes having a diameter of 100 mm or more, in particular, discharge for forming female and male flanges forming the flange mold at both ends of the primary molded synthetic resin tube Inserted into the insert portion of the head mold, the movable mold is closed, and the synthetic resin is melt-discharged and then cooled and separated to obtain a synthetic resin tube having female and male flanges formed at both ends.
한편 위와같이 암·수 플렌지를 합성수지관에 형성하는 이유는 합성수지관을 연결 매설할때 작업이 매우 신속·정확하게 이루어질수 있도록 하기 위함이며, 더불어 인력절감과 공기단축으로 시공에 따른 원가절감 효과를 극대화 시킬수 있도록 하기 위함이다.Meanwhile, the reason why the female and female flanges are formed in the synthetic resin pipe is to allow the work to be carried out very quickly and accurately when the synthetic resin pipe is connected and buried. In addition, it is possible to maximize the cost-saving effect of construction by reducing manpower and shortening the air. To make it work.
주치된 바와같이 길이가 매우 길고 직경이 비교적 큰 합성수지관은 제품 제조에 따른 특성상 압출이나 사출공법만으로는 제조가 어려워 주로형상으로 토출되는 합성수지 반죽을 별도의 회전금형을 이용하여 나선형으로 감아 연속제조하고, 이를 적절한 길이로 잘라 상·하수관으로 사용하는데, 이러한 상·하수관을 다수 연결시킬때는 두개의 관체가 맞닿은 부분에 밀폐용 씨트를 수회권취시킨후형으로 별도 형성된 두개의 이음부재를 맞대어 보올트와 너트로 조립고정시키거나, 열수축씨트를 수회권취시킨후 토치램프로 가열해준다음 스테인레스로 된형 이음부재를 씌워 보올트와 너트로서 체결고정시켜 주었던 것이다.As noted, synthetic resin tubes with very long lengths and relatively large diameters are often difficult to manufacture by extrusion or injection methods due to the characteristics of the product. Synthetic resin dough discharged in the shape is spirally wound using a separate rotating mold and continuously manufactured and cut into appropriate lengths to be used as water and sewage pipes. After winding the dragon seat several times The two joint members formed separately in the form are joined together and fixed with bolts and nuts, or the heat-shrink sheets are wound several times and then heated with a torch lamp. It was fastened by bolts and nuts with a type joint member.
그러나 이와같은 합성수지관 연결방법은 다음과 같은 점에서 많은 문제점이 노출되었던 것이다.However, the synthetic resin pipe connection method has been exposed a lot of problems in the following points.
즉 상·하수관을 연결시공할때 매우 번거롭고 불편하며, 인력과 시간이 과다하게 소요되어 시공비용이 많이 드는 것임에 반하여 수밀유지도 제대로 이루어질수 없는 폐단이 따르고, 더불어 관체가 이탈될 염려도 매우 컸던 것이며, 따라서 신뢰성이 크게 떨어졌던 것이다.In other words, when connecting the water and sewage pipes, it is very cumbersome and inconvenient, and it takes too much manpower and time, resulting in high construction costs. Therefore, the reliability was greatly reduced.
물론 위와같은 문제점들을 해결하기 위해서는 합성수지 관체 양단부에 플렌지를 형성시키면 되지만, 앞에서도 잠깐 설명하였다시피 압출방법을 이용하면 파이프와 같은 관체이외에는 제조가 현실상으로 불가능하고 사출로 제조하게 되면 금형비가 고가로 들면서 관체 길이를 길게 할수 없게되어 이또한 현실적으로 제조가 불가능하다.Of course, in order to solve the above problems, it is necessary to form flanges at both ends of the synthetic resin tube, but as mentioned earlier, if the extrusion method is used, it is impossible to manufacture other than a tube such as a pipe, and if it is manufactured by injection, the mold cost is high. It is impossible to lengthen the tube length, which is also impossible to manufacture in reality.
따라서 본발명은 전술한 종래의 제반문제점을 해결하기 위해 발명한 것으로, 특히 합성수지 관체를 통상의 방법으로 1차 압출성형한 후에 2차로 관체 양단부에 플렌지를 형성할수 있도록 2대의 압출기 또는 사출기 선단에 암·수 플렌지 형성용 토출헤드 금형과 이동금형을 설치하여 암·수 플렌지를 형성시킬수 있도록 하려는데 목적이 있는 것이다.Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, and in particular, after the primary resin extrusion is carried out by a conventional method in a conventional manner, the arms at the tip of two extruders or injection machines can be formed at the two ends of the pipe. · The purpose is to provide a male and female flange by installing a discharge head mold and a moving mold for forming a male flange.

At the same time, the movable molds 3 and 3 'which are opened and closed by the hydraulic cylinders 2 and 2' on the left and right sides of the discharge head molds 1 and 1 'are constructed so that the ordinary synthetic resin pipe 4 The process of forming the female and male flanges 42 and 42 'at both ends is as follows.
먼저 암·수 플렌지 형성용 토출헤드 금형(1)(1')에 돌출형성된 삽입부(11)과 삽입부(21)에 합성수지관(4)의 양단부를 끼우되, 상기 합성수지관(4)의 양끝단부가 정지턱(12)와 정지요부면(22)에 완전히 밀착되게 한 상태에서 유압실린더(2)(2')를 작동시켜 2등분된 이동금형(3)(3')들이 서로 밀착고정되게 한다.First, both ends of the synthetic resin tube 4 are inserted into the insertion portion 11 and the insertion portion 21 protruding from the discharge head mold 1 (1 ') for forming the male and female flanges. The hydraulic molds (2) and (2 ') are operated in a state in which both ends are brought into close contact with the stop jaw (12) and the recessed recessed surface (22). To be.
이어서 반용융 상태로 용융이송되는 합성수지가 압출기 또는 사출기의 이송스크류우(18)과 (28)에 의해 이송되어 합성수지 유도실(14')(24')를 각각 거쳐 토출공(14)(24)로 토출되게 되고, 토출된 합성수지는 암·수 플렌지 형성용 토출헤드 금형(1)(1')과 이동금형(3)(3') 사이에 충진되어 결국, 통상의 합성수지관(4) 양단부에 암·수 플렌지(42)(42')를 형성한다.Subsequently, the synthetic resin melt-transferred in the semi-melt state is transferred by the conveying screws 18 and 28 of the extruder or the injection machine, and discharged through the synthetic resin induction chambers 14 'and 24', respectively, to the discharge holes 14 and 24. The discharged synthetic resin is filled between the discharge head mold (1) (1 ') and the moving mold (3) (3') for forming the male and female flanges, and finally, at both ends of the ordinary synthetic resin tube (4). Female and female flanges 42 and 42 'are formed.
한편, 토출공(14)(24)을 통하여 합성수지가 토출되어 토출헤드 금형(1)(1')과 이동금형(3)(3') 사이에 완전히 충진되기 까지는 토출헤드 금형(1)(1')는 적정온도로 가열되어 있어야 하는데, 이는 헤드금형(1)(1') 외주면과 후면에 설치된 히터(20)(20')와 (30)(30')에 의해 가열되어 있게되므로 합성수지가 안정적으로 토출되게 되고, 완전히 토출된 다음에는 입수관(19)와 (29)를 통하여 냉각실(17)로 냉각수가 연속 공급되어지면서 출수관(19')(29')을 거쳐 배출되며 동시에 이동금형(3)(3')에도 냉각수가 공급 순환되게 되어 토출된 암·수 플렌지(42)(42')가 응고되게 되는 것이며, 완전히 응고된 다음에는 이동금형(3)(3')을 개방시킨후 합성수지관(4)을 인출하면 된다.On the other hand, until the synthetic resin is discharged through the discharge holes 14 and 24 and completely filled between the discharge head molds 1, 1 'and the moving molds 3, 3', the discharge head molds 1, 1 ') Should be heated to an appropriate temperature, because the resin is heated by heaters 20, 20' and 30, 30 'installed on the outer circumferential surface and the rear of the head mold (1) (1'). It is discharged stably, and after it is completely discharged, the cooling water is continuously supplied to the cooling chamber 17 through the water intake pipes 19 and 29 and discharged through the water discharge pipes 19 'and 29' and simultaneously moved. Cooling water is also supplied to the molds 3 and 3 'so that the discharged female and male flanges 42 and 42' are solidified. After the solidification is completely solidified, the movable molds 3 and 3 'are opened. After that, the synthetic resin pipe 4 may be taken out.
위와같이 완성된 합성수지관(4)은 두개 이상의 관을 연결시키기가 매우 손쉽고 간편한데, 그 이유는 합성수지관(4)의 암플렌지(42)에 형성된 삽입요홈(44)에 다른 합성수지관(4)의 수플렌지(42')에 형성된 삽입돌부(44')를 끼운다음 체결공(43)과 (43')를 일치시켜 보올트와 너트로 체결하면 되기 때문이며, 통상 삽입돌부(44')의 길이를 삽입요홈(44)보다 약간더 길게하고 삽입돌부(44')와 삽입요홈(44)이 테이퍼져 있는 상태이기에 밀착면적이 매우 넓어져서 수밀유지 또한 확실하게 이루어지게 되어 신뢰성이 극대화될수 있게 되는 것이다.Synthetic resin tube (4) completed as described above is very easy and simple to connect two or more tubes, the reason is the other synthetic resin tube (4) in the insertion groove 44 formed in the arm flange 42 of the synthetic resin tube (4) This is because the insertion protrusion 44 'formed on the male flange 42' of the fitting hole 43 and 43 'is matched with the bolt and the nut, and then the length of the insertion protrusion 44' is normal. Slightly longer than the insertion groove 44 and the insertion protrusion 44 'and the insertion groove 44 is in a tapered state so that the contact area is very wide, so that the watertight maintenance is also made surely, thereby maximizing reliability. .
상술한 바와같이 본발명은 통상의 합성수지관의 양단부에 암·수 플렌지를 형성할수 있도록 한 암·수 플렌지 형성용 토출헤드 금형(1)(1')과 이동금형(3)(3')을 제공함으로써, 합성수지관의 양단부에 암·수 플렌지를 매우 효과적으로 형성할수 있도록 한 것으로 합성수지관 이음작업시 인력·시간등을 크게 절감시킬수 있게 하는 매우 유용한 발명인 것이다.As described above, the present invention provides a discharge head mold (1) (1 ') and a moving mold (3) (3') for forming a female / female flange for forming a female / male flange at both ends of a conventional synthetic resin tube. By providing, the female and male flanges can be formed very effectively at both ends of the synthetic resin pipe, which is a very useful invention that can greatly reduce manpower and time during jointing of the synthetic resin pipe.
