본 발명온 배수용 파이프의 내벽에 나선형 돌기를 형성하여 배출되는 폐수의 효율을 극대화 하도록된 나선돌기가 형성된 배수용 파이프의 압출장치에 관한 것이다. 건물에 배환되는 배수용 파이프의 폐수배출효율을 극대화 하기위하여 배수용 파이프의 내벽에 다수의 나선형 돌기를 형성함으로써 유입되는 폐수가 파이프의 내부에서 회전하여 와류현상을 유발시켜 신속하게 폐수를 배출할 수 있으며, 배수용 파이프의 내벽과 유입된 폐수의 마찰에 의하여 심한 소음이 발생하는 것을 방지하였다.The present invention relates to an extrusion apparatus for a pipe for forming a spiral protrusion formed with a spiral protrusion on the inner wall of the pipe for drainage to maximize the efficiency of the discharged wastewater. In order to maximize the wastewater discharge efficiency of the drainage pipe returned to the building, a number of spiral protrusions are formed on the inner wall of the drainage pipe, so that the incoming wastewater rotates inside the pipe, causing vortexing to discharge the wastewater quickly. In addition, the noise generated by friction between the inner wall of the drainage pipe and the introduced wastewater was prevented.

본 발명은 이와 같은 나선돌기가 형성된 배수용 파이프를 제조하기 위한 압출장치에 관한 것으로, 종래의 파이프 압출장치에 간단한 가공으로 설치하여 상용할 수 있도록 구성한 것으로서 이하 첨부도면을 참고하여 상세히 설명하고자 한다.The present invention relates to an extrusion apparatus for manufacturing a pipe for drainage formed with such a spiral projection, it will be described in detail with reference to the accompanying drawings as configured to be commercially installed by a simple processing in a conventional pipe extrusion apparatus.

제1도에 도시된 바와 같이, 통상의 압출다이스(1)와 압출헤드(2)의 내경다이(3)중앙에 압출통로(4)가 관통된 회전다이(5)를 축설하되, 이 회전다이(5)의 압출헤드(2)쪽 말단에 나팔형 확산관(6)을 고정하고, 이 확산관(6)의 내측에는 다수의 요홈(8)이 요설된 원추형 고정헤드(7)를 부착하였으며, 타측 끝에는 체인기어(9)가 고정된 연결관(10)을 고정하여서 된 것이다.As shown in FIG. 1, a rotary die 5 having an extrusion passage 4 penetrated in the center of a conventional extrusion die 1 and an inner diameter die 3 of the extrusion head 2 is provided. A trumpet-shaped diffusion tube 6 is fixed at the end of the extrusion head 2 at (5), and a conical fixed head 7 having a plurality of grooves 8 is attached to the inner side of the diffusion tube 6. On the other end, the chain gear 9 is fixed to the connection pipe 10 is fixed.

미설명부호 11,11'는 압출통로 12,12'는 송입구, 13은 배출구, 14는 돌기이다.Reference numerals 11 and 11 'denote extrusion passages 12 and 12', inlets, 13 outlets, and 14 projections.

이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

압출다이스(1)의 송입구(12)에 원료를 압압하면, 압출통로(11)를 통하여 압출헤드(2)로 이송하여 배출구(13)로 압출함으로써 파이프(P)를 연속적으로 압출 성형하게 되는바, 회전다이(5)의 일측의 송입구(12')에도 원료를 압압하여 압출통로(4)가 이동시켜 회전다이(5) 말단의 나팔형 확산관(6)으로 압압하여준다.When the raw material is pressed into the inlet 12 of the extrusion die 1, the pipe P is continuously extruded by being transferred to the extrusion head 2 through the extrusion passage 11 and extruded to the outlet 13. The raw material is pressed into the inlet 12 'of one side of the rotary die 5, and the extrusion passage 4 is moved to press the trumpet-shaped diffusion tube 6 at the end of the rotary die 5.

이때, 회전다이(5)는 구동모우터(도시되지 않음)와 연결된 체인기어(9)가 서서히 회전함에 따라 회전다이(5) 또한 회전하게 되는 것이다.At this time, the rotary die 5 is to rotate the rotary die 5 as the chain gear 9 connected to the drive motor (not shown) gradually rotates.

이와 같이하여 회전하는 회전다이(5)의 압출통로(4)를 따라 이송된 원료는 확산관(6)의 내측에 고정된 원추형 고정헤드(7)의 요홈(8)으로 배출되어, 압출헤드(2)의 말단 배출구(13)에서 접촉하며, 내경다이(3)에 의하여 압출되는 파이프(P)에 일체로 돌기(14)를 형성하게 되는 것이어서, 회전다이(5)가 회전함에 따라 파이프(P)에 성형되는 돌기(14)는 나선헝을 이루면서 파이프(P)의 내벽에 돌출성형되는 것이다.In this way, the raw material conveyed along the extrusion passage 4 of the rotating die 5 is discharged to the groove 8 of the conical fixed head 7 fixed inside the diffusion pipe 6, and the extrusion head ( The protrusion 14 is formed integrally with the pipe P extruded by the inner diameter die 3 by contacting at the distal outlet 13 of 2), so that the pipe P is rotated as the rotary die 5 rotates. The protrusions 14 formed in) are projected to the inner wall of the pipe P while forming a spiral.

특히, 회전다이(5)의 말단 확산관(6)에 설치되는 고정헤드(7)에 요입되는 요홈(8)의 갯수를 조절함으로써 압출되는 파이프(P)의 내벽에 성형되는 나선형 돌기(14)의 갯수를 간단하게 조절할 수 있는 것이다.In particular, the spiral protrusion 14 formed on the inner wall of the pipe P to be extruded by adjusting the number of grooves 8 recessed in the fixed head 7 installed in the terminal diffusion pipe 6 of the rotary die 5. You can easily adjust the number of.

이상에서 설명한 바와 같이 본 발명은 그 구조가 극히 간단하여, 종래 사용되고 있는 파이프 제조용 압출다이스에 간단한 가공으로 설치할 수 있으므로 경제적으로 생산할 수 있는 것이다.As described above, the present invention is extremely simple in structure, and thus can be economically produced since it can be installed in a conventional extrusion die for pipe manufacture by simple processing.
