Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 공통 밸브 제어 배출구를 지니고 스크루 압출기에 의해 공급되는 한 쌍의 유압 램 압출기를 지니는 예비 성형장치의 입면도.
제2도는 압출기의 유압 핸들 사이의 유압 회로부를 포함하는 제1도의 예비 성형기의 개략도.
제3도는 완전한 유압 회로도.
Claims (9)
- 유동성 재료로 블랭크(blank)를 압출 성형하는 장치에 있어서, 상기 유동성 재료의 압출물을 방출하는 배출구를 지니는 한쌍의 유압 램 압출기, 압출될 유동성 재료 공급수단, 공급수단을 압출기의 배출구에 연결시키고 랩 압출기들 중 어느 것으로부터의 압출물을 방출하는 공통 배출구를 지니는 밸브수단, 실제로 같은 체적의 블랭크를 형성하도록 압출물의 방출속도에 따라 배출구에서 압출물을 반복적으로 절단하는 수단을 포함하며, 상기 밸브수단은 하나의 상기 압출기가 압출물을 상기 공통 배출구로 방출하도록 그 배출구에 연결되어 있는 중에 다른 압축기를 충전시키도록 공급수단을 다른 공급수단에 연결시키도록 작동하고, 그 역으로도 작동 가능하며, 폐쇄 유압회로가 2개의 램 압출기들의 유압 램들을 연결함으로써 하나의 램 압출기가 압출물에 충전되면 그 압출기의 램이 후퇴하여 압력 유체를 그 램으로부터 상기 유압회로를 통해 다른 압출기의 램으로 강제하여 그 다른 압출기의 램이 전진하여 밸브기구를 통해서 공통 배출구로 재료를 배출하여 그 역으로도 작동 가능한 블랭크 압출 성형장치.
- 제1항에 있어서, 유압 램들중 하나의 램의 예정된 전진 후퇴에 상응하는 간격으로 압출물을 절단하여 실제로 균일한 체적의 블랭크를 제조하도록 유압 램들중 하나의 저진 후퇴에 응하여 압출물을 절단하는 수단에 제어 수단이 설치되어 있는 장치.
- 제1항 또는 제2항에 있어서, 하나의 램의 전진의 완료 및 다른 램의 후퇴의 완료에 응하여 상기 밸브 수단을 한 위치로부터 다른 위치로 자동적으로 전환시키고 그 역으로도 작동하는 수단이 제공되어 있는 장치.
- 제3항에 있어서, 각각의 램은 그와 함께 이동하는 종동 부재를 지니며, 상기 전환수단을 자동적으로 작동시키기 위하여 램의 행정의 한계를 탐지하도록 이격된 접근 감지기가 제공되어 있는 장치.
- 전기 항들중 어느 한 항에 있어서, 밸브수단은 가동 밸브 부재가 장착되는 밸브 챔버를 지니는 밸브체를 포함하며, 밸브체는 램 압출기, 스크루 압출기에 연결되는 챔버내로 개방하고 밸브 부재에 의해 제거되는 이격된 밸브 포트를 지니는 장치.
- 제5항에 있어서, 밸브체가 상기 밸브 챔버를 제공하는 원통형 슬리브를 지니며, 상기 포트들은 슬리브 둘레에 이격되어 있고, 밸브 부재는 스크루 압출기를 램 압출기중 하나에 연결시키고 다른 압출기를 공통 압출기에 선택적으로 연결시키도록 슬리브내에 회전하게 장착되어 있는 장치.
- 전기 항들중 어느 한 항에 있어서, 공통 배출구가 압출 다이를 수용하며, 절단 수단은 다이로부터 나오는 압출물을 절단하도록 다이를 가로 질러 이동하도록 다이에 인접해서 장착된 절단기 날을 포함하는 장치.
- 제7항에 있어서, 램들중 하나의 저지 후퇴를 탐지하고, 램의 예정된 이동이 발생하여 예정된 체적의 재료가 압출된 것을 표시할 때마다 절단수단을 작동시키는 수단이 제공되어 있는 장치.
- 전기 항들중 어느 한항에 있어서, 밸브 수단에 유동성 재료를 공급하는 수단이 스크루 압출기 또는 다른 형태의 펌프를 포함하는 장치.※ 참고사항: 최초출원 내용에 의하여 공개하는 것임.
