Abstract

본 발명은 각종 배관에 사용되는 나선형호스와 그 제조방법 및 장치에 관한 것으로 특히, 연질과 경질의 합성수지를 동시에 압출하여 이를 나선형으로 권취토록 하므로서 내구성과 유연성 및 복원성을 우수하게 한것에 관한 것이다.
종래에는 주름관 형상의 금형에 연질의 합성수지를 공급하고 이의 내부에 공기를 불어넣는 방법을 이용하여 단면이형태로 되는 주름관 형사의 호스를 제조하여 왔으나 이 또한 유연성과 압력에 대응하는 성능은 우수한 반면, 일단 한번 압력을 받아 찌그러지게되면 복원이 불가능한 결점과 함께 내구성이 떨어지는 문제점이 있었으며, 호스내면에 요입부가 형성되므로 이 때문에 유체의 흐름이 원활하게 못하였고 이를 장기간 사용할시에는 요입부내로 이 물질이 끼게 되는 문제점과 함께 제조공정이 복잡하여 지게 되는 등의 문제점이 발생하였다.
본 발명은 이와같은 지금까지의 문제점을 해결하기 위하여 연·경질의 합성수지를 1개의 다이스를 공유하는 압출기를 통해 동시에 나선형으로 압출하여 연질의 합성수지가 본체를 이루도록 하고 경질의 합성수지가 심재를 이루도록 하므로서 호스의 내구성과 유연성 및 복원성을 향상시킴은 물론 제조공정을 단순화 시킨 것이다.

Claims (3)

  1. 경질의 합성수지로 되는 심재(2') 연질의 합성수지로 압출되는 띠형상의 단위소재(1') 중심외방에 매립되도록 일체로 동시 압출하여, 이를 경화되지 않는 상태에서 나선형으로 회전 권취하므로서 단위소재(1') 중첩부위가 상호 융착되도록 하여 관형으로 형성되도록 한 후 이를 냉각, 성형하여서 나선형 호스(5)를 제조토록 한 나선형 호스의 제조방법.
  2. 일측에 다이스(3)를 공유하는 압출기(1)(2)를 설치하고, 이의 전방에 파형회전기(4)를 설치하며, 이와 연접하여 냉각조(6)와 절단기(7)를 설치하여서된 나선형 호스의 제조장치.
  3. 연질의 합성수지로 되는 본체(5')외연에 경질의 합성수지로 되는 심재(2')를 일정피치를 갖도록 나선형으로 매립형성 하여서 된 나선형 호스(5).
