Description

열가소성 플라스틱 관을 성형하는 개선된 방법과 장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 발명에 따른 방법과 장치로 만들어진 열가소성 플래스틱 관의 측면도,
제2도는 요구되는 모양으로 관을 보지하는 지그(jig)의 측면도.

Claims (13)

  1. (a)요구되는 모양에 본질적으로 상응하는 최소한 하나의 성형기 위에 열가소성 플라스틱 물질의 관의 길이를 외부적으로 지지하기; (b)관이 성형기 위해 지지될때 적외선 방사에 의해 판을 가열하기; (c)열가소성 플라스틱 물질이 성형기의 모양으로 변형되기에 충분히 형성력이 생기도록 적외선 방사의 호출을 제어하고 관을 가열하기; (d)모양을 유지하도록 변형된 관을 냉각하기; (e)성형기로부터 모양잡힌 관을 제거하기로 특징지워지는 원하는 모양으로 열가소성 플라스틱 물질의 관을 성형하는 방법.
  2. 제1항에 있어서, 적외선 방사의 펄스화되거나 간헐적 방출로 관을 가열하는 것을 특징으로 하는 방법.
  3. 제1항 또는 제2항에 있어서, 0.7 에서 2.0마이크톤 선호적으로 약 1마이크톤의 첨두 에너지 방출을 갖는 단파장 적외선 방사로 관을 가열하는 특징을 갖는 방법.
  4. (a)원하는 모양에 본질적으로 상응하는 열가소성 플라스틱 물질의 관(1; 101; 201)의 길이를 외부적으로 지지하기 위한 성형기 수단(5,6,7,8;105;205), (b)적외선 방사의 제어된 방출에 의해 관(1;101;201)을 가열하는 적외선 방상원 (30;130;230), (c)원하는 모양을 갖도록 관 (1:101:201)을 냉각하는 냉각유체원(34)로 특징지워지는 원하는 모양으로 열가소성 플라스틱 물질관을 성형하는 장치.
  5. 제4항에 있어서, 관(1;101;201)은 성형기수단(5,6,7,8)의 안내표면(5a,6a,7a,8a)위에 외부적으로 지지되는 특징을 갖는 장치.

  10. 제4항에서 9항까지중 어느 한 항에 있어서, 예를 들어 공기 같은 냉각유체원(34)는 성형기수단(5,6,7,8)의 관한 각 위치 및/혹은 그것으로부터의 거리를 변화시키도록 조절되는 하나나 그 이상의 배출구(33)에 연결되는 특징을 갖는 장치.
  11. 제4항에서 10항까지중 어느 한 항에 있어서, 적외선 방사원(30;130;230)은 적외선 방사의 펄스화되거나 간헐적 방출을 위한 제어수단(28)에 의해 작동되는 특징이 있는 장치.
  12. 제4항에서 11항까지중 어느한항에 있어서, 성형기수단(5,6,7,8)은 냉각유체원(34)와 적외선 방사원(30)에 관해 운동하도록 대 테이블이나 플랫포옴(flatformm)(4)위에 장착되는 특징이 있는 장치.
  13. 제12항에 있어서, 성형기수단(5,6,7,8)은 대 테이블(4)위에 장착된 다수의 성형기(5,6,7,8)을 구성하고 성형기(5,6,7,8)은 서로에 관해 조절되고 혹은 다음 원하는 관 모양을 위해 상호 교환되는 특징이 있는 장치.
