Description

가공 경화성 고합금튜브의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 냉간가공으로 강화된 재료로 만들어진 예비성형 튜브의 측단면도
제2도는 튜브의 전체길이에 걸쳐 냉간가동을 행하여 단면 적을 축소시키는 한편 길이는 늘리고 최종적인 요구칫수에 맞도록 기타 다른 부분의 칫수를 조절한 후의 튜브단면도
제3도는 예비성형된 튜브를 냉간 가공시키기 위해 사용되어지는 정밀회전단도 장치의 개략측면도
-도면의 주요 부분에 대한 부호의 설명-

Claims (10)

  1. 냉간가동으로 강화되어진 재질을 가지고 하나이상의 확대 선단부를 갖는 튜브를 제조하는 방법에 있어서, 상기한 재질로서 하나의 몸통부와 최초 제작시의 외경, 벽두께, 내경 길이 및 횡단면적을 갖는 예비성형 튜브를 제조하고, 이어 상기 예시성형된 튜브의 외경과 벽두께 및 횡단면적을 줄임과 동시에 길이를 최종의 요구칫수로 늘리는 한편 몸통부와 선단부 전체가 강화되도록 냉간가공하는 것을 특징으로 하는 튜브의 제조 방법.
  2. 제1항에 있어서, 냉간가공시에 예비성형된 튜브를 냉간 가공하기 위해서, 최소한 상기 튜브의 1선단부를 붙잡아주는 회전 및 이동이 가능한 클램핑헤드(36,37)와, 튜브(10)의 내면에 끼워지는 굴대헤드(40) 및 튜브(10)의 외면을 타격하는 햄머(42) 등이 갖춰진 회전냉간단조 장치(30)를 이용하는 것.
  3. 제1항에 있어서, 냉간가공시에 예비성형된 튜브를 냉간가공시키기 위하여 튜브(10)의 1선단을 붙잡아주는 회전 및 이동이 가능한 클램핑 헤드(66)와 튜브내면에 끼워지는 굴대헤드(70) 및 튜브(10)의 외면과 접촉하는 최소한 하나의 접촉로울러(72)를 갖춘 외부 회전압출장치를 이용하는 것
  4. 제1항에 있어서, 냉간가공시에 예비성형 튜브(10)의 내면속으로 굴대헤드(40)를 끼워넣고 상기 굴대헤드 부근의 튜브 외면을 가공하는 방법
  5. 제4항에 있어서, 예비성형된 튜브를 냉간가공하는 동안 굴대헤드(40)와 튜브(10) 내면중 최소한 한면을 윤활시키는 방법
  6. 제5항에 있어서, 냉간가공을 하는 동안 굴대헤드(40)와 튜브(10) 내면 모두를 윤활시키는 방법
  7. 제1항에 있어서, 냉간가공시에 최초의 균일하게된 튜브의 한쪽 선단을 압축 확대시켜 하나이상의 확대 선단부를 갖도록 제조하는 방법
  8. 제7항에 있어서, 압축확대시에 초기의 균일한 튜브선단을 열간압축시키는 방법
  9. 제7항에 있어서, 압축확대시에 초기의 균일한 튜브선단을 냉간압축시키는 방법
  10. 제1항에 있어서, 예비성형된 튜브를 최초 균일한 몸체부와 하나이상의 선단부를 갖도록 가공하는 방법
    ※ 참고사항: 최초출원 내용에 의하여 공개하는 것임.
