본 발명은 유리섬유 복합관의 가공에 사용되는 장치에 관한 것이다.The present invention relates to an apparatus used for processing a glass fiber composite tube.

유리섬유 복합관이란 합성수지가 함침된 유리섬유를 내외층으로 하고 그 사이에 모르타르층을 형성한 관을 말하며, 상하수도관, 가스공급관, 공업용 관로관 등에 주로 사용된다. Glass fiber composite pipe refers to a pipe in which a synthetic resin impregnated glass fiber is used as an inner and outer layer and a mortar layer is formed therebetween.

이러한 유리섬유 복합관은 고압연료 용기와 같이 필라멘트 와인딩 공법으로 제조되어 왔는데, 필라멘트 와인딩 공법이란 수지가 함침된 연속섬유를 회전하는 심축 위에 감아서 주로 파이프나 압력용기, 로켓 모터 케이스 등과 같은 축대칭 복합재료 구조물을 제작하는 방법을 말한다.Such glass fiber composite tube has been manufactured by filament winding method like high pressure fuel container. Filament winding method is mainly a shaft-symmetric composite material such as pipe, pressure vessel, rocket motor case, etc. The method of making a structure.

필라멘트 와인딩 성형은 심축의 회전속도와 섬유의 공급위치를 이동시키는 캐리지(carriage)의 속도를 조절하여 일정한 와인딩 각도와 패턴으로 수지가 함침된 연속섬유를 심축에 감을 수 있는 성형기를 이용하며, 설계상의 두께까지 와인딩되면 와인딩된 심축을 와인딩기에서 떼어내어 경화로(curing oven) 안의 회전축에 걸고 회전시키면서 경화시킨다.Filament winding molding uses a molding machine that can wind continuous fibers impregnated with resin at a constant winding angle and pattern on the mandrel by adjusting the rotational speed of the mandrel and the speed of the carriage that moves the feeding position of the fiber. When winding up to thickness, the wound mandrel is detached from the winder and cured while rotating on a rotating shaft in a curing oven.

종래에는 상기와 같이 경화된 유리섬유 복합관을 소정의 길이로 절단한 다음 순차적으로 챔퍼링 및 그라인딩하는 방식으로 제작을 완료하였다. 따라서 넓은 공간이 필요했으며 가공에 소요되는 시간이 많아서 생산성이 떨어지는 원인이 되었다. Conventionally, the glass fiber composite tube cured as described above was cut to a predetermined length, and then the production was completed by chamfering and grinding sequentially. Therefore, a large space was required, and the time required for processing was a cause of decrease in productivity.

본 발명은 상기한 종래기술의 문제점을 감안하여 창작된 것으로, 절단한 유 리섬유 복합관을 다시 그라인딩 및 챔퍼링 가공할 필요가 없으며 추가의 장비를 설치하지 않고도 생산성을 향상하는데 그 목적이 있다.The present invention has been made in view of the above-mentioned problems of the prior art, and does not need to grind and chamfer the cut glass fiber composite pipe again, and its object is to improve productivity without installing additional equipment.
