Abstract

본 발명은, 제1 호스 단부(5)를 조인트에서 제2 호스 단부(9)와, 제1 호스 단부의 둘레에서 연장되는 시임(seam)으로 용접하는 용접 방법으로서, 보호층(7)이 우선 제1 호스 단부(5)의 조인트에 도포되고, 그 후에 제2 호스 단부(9)가 제1 호스 단부(5) 위에서 조인트를 넘어 가압되며, 호스 단부(5, 9)들이 궁극적으로, 서로를 향해 이동되는 2개의 클램핑 죠오((clamping jaw))(10, 14) 사이에서, 조인트에서 함께 평평하게 가압되고, 호스 단부들이 이 상태로 함께 용접되며, 보호층(7)은 제1 호스 단부(5)의 내부(6)의 용접을 방지하는 것인 용접 방법을 제공한다.

Description

용접 방법
본 발명은 제1 호스 단부의 둘레에서 연장되는 시임(seam)에서 제1 호스 단부를 제2 호스 단부와 조인트에서 용접하는 용접 방법으로서, 제1 호스 단부의 조인트에 보호층이 먼저 도포되고, 제2 호스 단부가 제1 호스 단부 위에서 조인트를 넘어 압박되며, 호스 단부들이 궁극적으로, 서로를 향해 이동되고 있는 2개의 클램핑 죠오(clamping jaw) 사이에 있어서 조인트에서 함께 평평하게 가압되고, 이 위치에서 함께 용접되며, 상기 보호층이 제1 호스 단부 내부에 도포되고, 제1 호스 단부 내부의 용접을 방지하는 것인 용접 방법을 제공한다.
US 6,540,859 B1에는 급수 호스를 스플라이싱(splicing)하기 위한 이러한 일반적인 유형의 방법이 개시되어 있다. 소위 "캣아이(cat eye)"가 호스의 압축 중에 호스 단면의 양 단부에 형성된다. 호스는 그 둘레의 적은 부분에서 180°편향되며, 이 경우에 외측부는 연신되고 내측부는 압축된다. 호스의 개방 중에, 이에 따라 내측부는 연신된다. 이 위치에 도입되는 용접부는 이에 따라 약화된다.
US 6,090,233 A 및 WO 97/06954 A1은 2개의 호스 단부를 용접하기 위해, 전분, 왁스지, 섬유유리, 면, 울, 석면 또는 Teflon®로부터 형성된 평평한 차열부로 구성된 보호층을 급수 호스의 호스 단부 내부로 삽입하는 것을 제안한다. 기지의 방법을 이용하여 호스 단부를 용접함으로써 차열부의 양쪽 측방향 에지에서 누설이 발생한다.
US 2,623,571은 차량 휠을 위한 내측 공기관을 제조하는 방법으로서, 양 단부가 베벨 원추(beveled cone)이고, 이에 따라 깔대기 형상이며, 함께 용접되는 방법에 관한 것이다.
본 발명의 목적은 용접부의 기밀성을 향상시키는 것이다.
기지의 방법을 개선하기 위해, 본 발명에 따르면 호스 단부는 초기에, 2개의 제1 부분 시임을 용접한 후에 세워진 다음, 다시 제1 부분 시임에 대해 횡방향으로 함께 평평하게 가압되며, 2개의 추가의 부분 시임에서 용접되고, 제1 부분 시임과 추가의 부분 시임이 시임을 형성하는 것이 제안된다. 2 단계 용접은 "캣 아이"에서의 약화를 방지한다. 이에 따라, 특히 호스 단부의 벽 두께가 두꺼운 경우에 누설 기밀성이 더욱 증가된다.

유리하게는, 제1 부분 시임과 추가의 부분 시임은 본 발명에 따른 둘레의 상이한 부분들을 커버한다. 용접과 동시에, 레터링 또는 다른 마킹이 제2 호스 단부에 적용될 수 있다. 마킹의 크기는 클램핑 죠오의 크기, 이에 따라 각각의 부분 시임의 크기로 제한된다. 상이한 길이의 부분 시임에 의한 2 단계의 비대칭 용접은 긴 부분 시임으로 인해 호스 상의 보다 큰 마킹을 용이하게 한다.
유리하게는, 제1 부분 시임과 제2 부분 시임은 중첩된다. 이에 따라, 제1 부분 시임과 제2 부분 시임 사이의 갭이 회피된다. 더욱 유리하게는, 제1 부분 시임과 제2 부분 시임은 함께 최대로, 둘레의 120 %를 커버한다.
유리하게는, 보다 긴 클램핑 죠오와 이에 따라 보다 긴 부분 시임은 둘레의 60 % 이상을 커버한다. 더욱 유리하게는, 보다 긴 클램핑 죠오는, 과도한 기계적 하중과, 이에 따라 “캡 아이”에서의 압출재에 대한 손상을 방지하기 위해 둘레의 80 % 이하를 커버한다.
보호층은 본 발명에 따른 방법에 따르면 둘레의 절반으로 제한될 수 있다. 내부의 용접을 방지하기 위해, 보호층을 클램핑 죠오 사이에 삽입할 때에 둘레를 따른 보호층의 위치를 고려해야만 한다.
유리하게는, 제1 호스 단부 및/또는 제2 호스 단부는 본 발명에 따른 방법에서 열가소성 폴리우레탄 재료로 형성된다. 열가소성 폴리우레탄(TPU)은 특히 압출에 적합하다. 본 발명에 따른 방법은 특히 버어(burr) 없이 TPU 호스를 다른 열가소성 재료로 형성된 호스와 용접하는 데에도 또한 사용될 수 있다.
유리하게는, 호스 단부는 본 발명에 따른 방법에서 열용접된다. 열용접 방법, 이에 따라 용접 대상 표면이 충분히 용접되어 함께 유동하고 접합 유닛을 형성하는 방법은 특히 고주파수, 레이저 또는 전자 빔에 의해 수행된다. 대안으로서, 호스 단부는 또한 특히 용접 대상 표면을 일시적으로 부분 용해시키는 것에 의해 화학적으로 용접될 수 있다.
유리하게는, 클램핑 죠오는 본 발명에 따른 방법에서 투명하다. 투명 클램핑 죠오는 레이저 또는 전자 빔에 대해서 투과성이다.
유리하게는, 보호층은 본 발명에 따른 방법에서 롤러에 의해 내부에 도포된다. 대안으로서, 보호층은 상이한 방법, 예컨대 분사를 이용하여 내부에 도포될 수 있다. 더욱 유리하게는, 보호층은 내부에 대략적으로 도포될 수 있다.
유리하게는, 보호층은 본 발명에 따르면 용접 전에 경화된다. 대안으로서, 보호층은 도포 중에 이미 경화되는 재료로 형성될 수 있다.
유리하게는 보호층은, 본 발명에 따른 방법에서 경화 후에 적어도 250 ℃까지 내열성이 있는 래커(lacquer)로 형성된다. 폴리에스테르, PVC-혼합물, 혼합 폴리머리세이트(polymerisate), 폴리비닐 아세테이트, 폴리비닐 부티랄, 니트로 셀루로오스, 아세틸 셀룰로오스 또는 셀룰로오스 아세테이트를 주성분으로 하는 내열성 래커가 잘 알려져 있다. 대안으로서, 보호층은 내열성 포일, 예컨대 금속 포일, 특히 용접 전에 내부에 도포되는 알루미늄으로 형성될 수 있다.
본 발명은 더욱이, 차량 휠용 내부관 제조 방법으로서, 압출재로 성형된 무단 호스로부터 블랭크가 절단되고, 토러스(torus) 형상으로 폐쇄되며, 블랭크의 2개의 호스 단부가 용접되어 전술한 바와 같은 내부관을 형성하는 차량 휠용 내부관 제조 방법을 제안한다. 이러한 타입의 일반적인 내부관 제조 방법은 당업계에 알려져 있다.
이어서, 본 발명을 첨부도면을 참고하여 실시예를 기초로 설명된다.
도 1은 내부관을 관통하는 단면도.
도 2는 본 발명에 따른 방법의 상세도.
본 발명에 따른 방법에서, 도시하지 않은 29" 자전거 휠을 위한 내부관(1)이 제조된다. 내부관(1)은 도 1에서 조인트의 단면으로 도시되어 있으며, 실축척은 아니다. 내부관(1)은 30 mm의 외경(2)을 갖는다. 내부관(1)의 벽 두께(3)는 350 μm이다. 내부관(1)은 폴리에스테르 베이스 상에의 열가소성 폴리우레탄(TPU)의 블로우 포일 압출(blow foil extrusion)에 의해 무단으로 제조된다.
압출재는 각각 호스 종축(4)과 정확하게 직교하는 2030mm의 비도시 블랭크로 절단된다.
블랭크의 제1 호스 단부(5)는, 내부(6)를 볼 수 있게 되고 내부에 용이하게 접근 가능하도록 개방된다. 소형 펠트 롤러를 사용하여, 내열성 투명 래커로 형성된 두께 대략 5 μm의 보호층(7)이 내부(6)에 둘레방향으로, 호스 종축(4) 방향으로 20 mm 두께로 도포딘다.
보호층(7)은 내부(6)의 전체 둘레를 웨팅(wetting)한다. 이에 따라, 용접 시임의 품질을 악화시키고, 심지어는 2개의 내부 포일을 서로 분리시킬 수 없게 되는 국소적으로 제한된 용접이 회피된다.
보호층(7)을 경화시키는 대략 30분의 건조 시간 후, 2개의 호스 단부가 대략 10 mm 중첩되도록, 제1 호스 단부(5)가 제2 호스 단부(9)에 삽입된다. 보호층(7)은 800 ℃까지 내열성이 있다.
제1 호스 단부(5)와 제2 호스 단부(9)는 도 2에 예시한 바와 같이 함께 평평하게 가압되고, 초기에 2개의 클램핑 죠오(10) 사이에서 고주파에 의해, 호스 폭의 대략 70 %에 대응하는 대략 33 mm의 길이(11)로 함께 용접된다. 이와 동시에, 제1 클램핑 죠오(10)는 제조업자의 로고와 기술 상세 및 내부관(1)의 테스트 시일을 조인트에 엠보싱 가공하고 프린트한다.
그 후, 내부관(1)은 캣아이(12) 부분에서 직립되고, 다시 제1 시임(13)을 가로질러 함께 평평하게 압박되며, 호스 폭의 대략 40 %에 상응하는 대략 19 mm의 길이(15)에 걸쳐 2개의 클램핑 죠오(14)들 사이에서 다시 함께 용접된다. 전극이 황동으로 형성되고, 호스 종축(4) 방향으로 5 mm의 폭 - 도시하지 않음 - 을 갖는다. 클램핑 죠오(10, 14)와 그리고 이에 따라 제1 부분 시임(13) 및 제2 부분 시임은 함께 둘레의 110 %를 커버한다.
