Description

폴리케톤으로 제조된 연료탱크 및 이를 제조하는 제조방법
본 발명은 폴리케톤으로 제조된 연료탱크 및 이를 제조하는 제조방법에 관한 것으로, 더욱 상세하게는, 상하부커버 2개의 부품을 동시 성형하여 취출 후, 기계를 통해 조립 후 바로 융착을 진행함으로써 자동화 및 대량생산이 가능한 폴리케톤으로 제조된 연료탱크 및 이를 제조하는 제조방법에 관한 것이다.
일반적으로 자동차의 연료장치는 엔진에 혼합기를 공급하는 장치로 혼합기를 만들어 엔진에 공급하는 기화기, 또는 연료를 엔진의 연소실에 분사하는 인젝터와, 이 기화기나 인젝터에 여과된 연료를 공급하는 연료펌프 및 연료를 저장하는 연료탱크 등으로 구성되어 있다.
상기한 바와 같은 부품들은 연료 파이프에 의해 서로 연결되어 있으며, 특히, 연료탱크는 얇은 강판으로 만든 탱크본체에 연료 주입구를 형성하는 필러호스를 연통 상태로 장착하여 연료를 상기 탱크본체에 넣을 수 있도록 하고 있다.
이러한 연료탱크는 대한민국 공개특허 공개번호 제10-2001-0030223호(이하 '특허문헌 1'이라 지칭함)과 같이, 사출 성형으로 1차 사출, 2차 사출, 융착 부분에 강성 보강물을 추가하는 방식이다. 즉, 1차, 2차 사출 후 별도의 후가공으로 융착을 보완하는 공정으로 이루어졌다.
그러나, 특허문헌 1은, 1차 성형 후 별도 후 공정(고정대 및 클램프, 섬유, 추가 이중사출, 열경화성 수지를 이용한 도브테일 가공)으로 연료탱크의 강성 및 융착 부분을 보완하였으나 제조 공법상 대량 생산 및 원가절감에 한계가 있으며, 연료 탱크를 구성하는 원재료의 물성이 한계가 있어서 융착 이후 별도의 공정(고정대, 섬유, 이중사출, 도브테일 등)을 통해 강성을 보강하여야 하는 문제점이 있었다. 이러한 강성보강을 위한 별도 보강 공정으로 중량 증가 및 원가 상승하는 문제점이 있었다.
또한, 대한민국 공개특허 공개번호 제10-2013-0033818호(이하 '특허문헌 2'라 지칭함)는, 블로우 성형으로 1차 사출, 2차 강성보강물 삽입, 3차 사출하는 방식이다. 즉, 1차 성형 후, 별도의 절단 가공 및 삽입 가공이 추가된 후 사출이 이루어진다.
그러나, 특허문헌 2는 1차 성형 후 별도 가공으로 절개를 한 후 다시 강성 보강물을 삽입한 상태로 2차 사출을 함에 따라, 후 가공 및 수작업이 필요하여 대량 생산 및 원가절감에 한계가 있었다.
또한, 특허문헌 2는 블로우 성형으로 탱크 내부에 유동성 소음 방지를 위한 칸막이를 구성할 수 없으며, 추가로 이를 구현하기 위해서는 별도의 구조물을 삽입하여야 했으며, 별도의 강성 보강물 삽입으로 중량 증가가 불가한 문제점이 있었다.
상술한 바와 같은 문제점을 해결하기 위해 안출된 본 발명의 목적은, 상부커버와 하부커버를 동시 성형하여 취출 한 후, 기계를 통해 조립하고, 상부커버와 하부커버를 융착시킴으로써, 자동화가 가능한 구조로 이루어지고 대량 생산이 가능할 뿐만 아니라, 획기적 원가 절감이 가능한 동시에, 별도의 보강물 없이 폴리케톤 원재료 강성만으로 필요 강성을 만족함에 따라 연료 탱크 경량화가 가능한 폴리케톤으로 제조된 연료탱크 및 이를 제조하는 제조방법을 제공하는데 있다.
상기한 바와 같은 목적을 달성하기 위한 본 발명의 폴리케톤으로 제조하는 제조방법에 따르면, 사출성형기를 통해 상부커버 및 하부커버를 사출성형하는 커버 사출단계; 상기 커버 사출단계를 통해 사출성형된 상부커버와 하부커버를 상하부에 각각 배치하여 조립하는 커버 조립단계; 및 상기 커버 조립단계에서 조립된 상부커버와 하부커버가 맞닿는 접촉면을 레이저로 융착시키는 커버 융착단계;를 포함한다.
또한, 상기 사출성형기를 통해 사출성형되는 상부커버 및 하부커버는, 폴리케톤(Polyketone) 소재를 통해 사출성형되어 강성이 향상되는 것을 특징으로 한다.
또한, 상기 커버 조립단계와 상기 커버 융착단계 사이에, 상기 상부커버 및 하부커버 중 어느 하나 이상의 외측면을 하나 이상의 롤러로 가압하는 커버 가압단계;를 더 포함하고, 상기 커버 융착단계는, 상기 커버 가압단계에서 롤러가 상기 상부커버 및 하부커버 중 어느 하나 이상의 외측면을 가압하는 동안 이루어지는 것을 특징으로 한다.
또한, 상기 상부커버와 하부커버의 테두리 단이 서로 대응되게 형성되되, 상기 상부커버 및 하부커버의 테두리 단 중 어느 하나의 테두리 단에는, 돌출된 돌출부가 형성되고, 다른 하나의 테두리 단은, 상기 돌출부가 내입되는 내입홈이 형성된 것을 특징으로 한다.

먼저, 커버 사출단계(S10)는, 사출성형기를 통해 상부커버(10) 및 하부커버(20)를 사출성형한다.
이때, 커버 사출단계(S10)는, 상부커버(10)의 테두리 하단과, 하부커버(20)의 테두리 상단이 각각 삽입되는 삽입홈(61)이 형성된 중간커버(60)를 더 사출성형할 수 있다.

폴리케톤이란, 일산화탄소와 에틸렌, 프로필렌을 공조합시켜 만드는 신소재이다.
이러한, 폴리케톤은 열과 마찰, 충격, 화학물질 등에 견디는 능력이 좋아 금속을 대체하는 공업용 플라스틱 소재로 쓰인다. 특히 플라스틱 나일론과 비교해 충격에는 2배, 마찰에는 최고 14배 뛰어나 자동차와 전자부품 등 산업용 소재로 쓰일것으로 예상된다.
커버 조립단계(S20)는, 커버 사출단계(S10)를 통해 사출성형된 상부커버(10)와 하부커버(20)를 상하부에 각각 배치하여 조립한다.
또한, 커버 조립단계(S20)는, 상부커버(10)와 하부커버(20) 사이에 중간커버(60)를 더 구비하여 조립할 수 있다.

또한, 커버 가압단계(S30)는, 중간커버(60)의 외측면을 하나 이상의 롤러(40)로 가압할 수 있다. 이때, 커버 가압단계(S30)는, 상부커버(10)를 하부커버(20)방향으로 롤러(40) 또는 다른 기기로 가압할 수 있다.
그리고, 커버 가압단계(S30)는, 하나의 롤러(40)를 이용하여 상부커버(10)와 하부커버(20)의 외측면, 상부커버(10)와 중간커버(60)의 외측면 및 상부커버(10)와 중간커버(60)의 외측면 중 어느 하나의 외측면을 동시에 가압할 수 있다.
커버 융착단계(S40)는, 커버 조립단계(S20)에서 조립된 상부커버(10)와 하부커버(20)가 맞닿는 접촉면을 레이저(50)로 융착시킨다. 이때, 레이저(50)는 레이저기기를 이용할 수 있다.
그리고, 커버 융착단계(S40)는, 상부커버(10)와 중간커버(60) 및 하부커버(20)와 중간커버(60)가 맞닿는 접촉면을 각각 레이저(50)로 융착시킬 수 있다.
여기서, 커버 융착단계(S40)는, 커버 가압단계(S30)에서 롤러(40)가 상부커버(10) 및 하부커버(20) 중 어느 하나 이상의 외측면을 가압하는 동안 이루어질 수 있다.
이와 같이 상술한 본 발명의 폴리케톤으로 제조하는 연료탱크 제조방법을 이용하면, 상하부커버(10, 20) 2개의 부품을 동시 성형하여 취출 후 기계를 통해 조립 후 바로 융착을 진행함으로 자동화가 가능한 구조이며 대량 생산이 가능할 뿐만 아니라, 획기적 원가 절감이 가능하다. 더불어, 별도의 보강물 없이 폴리케톤 원재료 강성만으로 필요 강성을 만족함에 따라 연료 탱크 경량화가 가능하다.
한편, 상술한 커버 사출단계(S10)를 통해 사출성형된 상부커버(10), 하부커버(20) 및 중간커버(60)에 대해 설명한다.
상부커버(10)와 하부커버(20)의 테두리 단이 서로 대응되게 형성되어 서로 맞닿으며 조립된다.
여기서, 상부커버(10)와 하부커버(20)의 테두리 단이 조립될 때, 상부커버(10)의 내측면 또는 외측면이 하부커버(20)의 내측면 또는 외측면과 서로 하나의 평면에 배치되어 유지됨에 따라 외력에도 어긋나지 않도록 형성되는 것이 바람직하다.
즉, 도 4에 도시된 바와 같이, 상부커버(10) 및 하부커버(20)의 테두리 단 중 어느 하나의 테두리 단에는, 돌출된 돌출부(11, 21)가 형성되고, 다른 하나의 테두리 단은, 돌출부(11, 21)가 내입되는 내입홈(12, 22)이 형성될 수 있다.
그리고, 돌출부(11, 21)는, 상부커버(10) 및 하부커버(20)의 테두리 단 중 어느 하나의 테두리 단 중앙에서 돌출형성될 수 있으며, 테두리 단의 내측면 또는 외측면이 연장되도록 돌출형성될 수 있다.
또한, 돌출부(11, 21)의 일측면과 내입홈(12, 22)의 일측면은, 커버 가압단계(S30)에서 상부커버(10) 및 하부커버(20) 중 어느 하나 이상의 외측면을 가압하는 롤러(40)의 가압력이 지지되도록 상부커버(10) 및 하부커버(20)의 외측면에 평행한 하나 이상의 지지면(30)이 형성된다.
이때, 지지면(30)의 양 끝단은 커버의 외측 또는 내측방향으로 대각방향 또는 직각으로 절곡되어 연장형성된다.
또한, 돌출부(11, 21)와 내입홈(12, 22)의 타측면은 대각방향으로 형성될 수 있다.
그리고, 커버 융착단계(S40)는, 커버 조립단계(S20)에서 조립된 상부커버(10)와 하부커버(20)가 맞닿는 접촉면 즉, 지지면(30)을 레이저(50)로 융착시킨다.
도 5를 참조하면, 상부커버(10)는, 테두리 외측면에 상부돌출턱(13)이 돌출형성된다. 이때, 상부돌출턱(13)의 하측면은, 상부커버(10)의 테두리 단 하측면과 연장형성되며 돌출부(11, 21)와 내입홈(12, 22)이 형성될 수 있다.
그리고, 하부커버(20)는, 테두리 외측면에 하부돌출턱(23)이 돌출형성된다. 이때, 하부돌출턱(23)의 상측면은, 하부커버(20)의 테두리 단 하측면과 연장형성되며 돌출부(11, 21)와 내입홈(12, 22)이 형성될 수 있다.
이때, 커버 가압단계(S30)는, 어느 하나의 롤러(40)가 상부돌출턱(13)의 상부에서 하부로 가압하고, 또 다른 어느 하나의 롤러(40)가 하부돌출턱(23)의 하부에서 상부로 가압한다.
여기서, 상부돌출턱(13)의 하측면과 하부돌출턱(23)의 상측면에는, 커버 가압단계(S30)에서 상부돌출턱(13)와 하부돌출턱(23)을 가압하는 롤러(40)의 가압력이 지지되도록 상부돌출턱(13)의 상측면 및 하부돌출턱(23)의 하측면에 평행한 하나 이상의 지지면(30)이 형성된다.
그리고, 커버 융착단계(S40)는, 커버 조립단계(S20)에서 조립된 상부돌출턱(13)와 하부돌출턱(23)가 맞닿는 접촉면 즉, 지지면(30)에 연장형성된 사선방향의 접촉면을 레이저(50)로 융착시킨다.
도 6을 참조하면, 커버 사출단계(S10)를 통해 사출형성된 중간커버(60)가 상부커버(10)와 하부커버(20)의 테두리 단 사이에 구비된다.
이때, 중간커버(60)는, 상하측면이 각각 대응되게 형성되며, 상하측면의 중간부분이 상부커버(10)의 테두리 하단에 형성된 돌출부(11, 21)와, 하부커버(20)의 테두리 상단에 형성된 돌출부(11, 21)가 각각 삽입되는 한 쌍의 삽입홈(61)이 형성된다.
그리고, 중간커버(60)의 내측방향인 삽입홈(61) 일측면은, 롤러(40)의 가압에 지지되도록 상부커버(10)와 하부커버(20)의 외측면과 평행한 지지면(30)이 수직방향으로 형성된다.
또한, 중간커버(60)의 한 쌍의 삽입홈(61)은 중간커버(60)의 외측으로 갈수록 상하폭이 넓어질 수 있도록 형성된다. 즉, 중간커버(60)의 외측방향인 삽입홈(61) 타측면은, 중간커버(60)의 외측면을 향해 대각방향의 빗면으로 형성된다.
그리고, 커버 융착단계(S40)는, 커버 조립단계(S20)에서 조립된 상부돌출턱(13)와 하부돌출턱(23)가 중간커버(60)와 맞닿는 접촉면 중 중간커버(60)의 삽입홈(61) 타측면과 맞닿는 접촉면을 레이저(50)로 융착시킨다.
도 7을 참조하면, 커버 사출단계(S10)는, 상부커버(10) 및 하부커버(20) 중 어느 하나 이상의 내측면에 연료 유동방지용 칸막이(70)가 형성되도록 사출형성한다.
이때, 상부커버(10)에 형성된 연료 유동방지용 칸막이(70)는, 상부커버(10)의 테두리 단보다 더 아래로 돌출된 지지턱(71)이 사출형성된다.
또한, 하부커버(20)에 형성된 연료 유동방지용 칸막이(70)는, 하부커버(20)의 테두리 단보다 더 위로 돌출된 지지턱(71)이 사출형성된다.
또한, 연료 유동방지용 칸막이(70)는, 상부커버(10) 및 하부커버(20)의 내측면에 모두 형성되되, 지지턱(71)은 교대로 형성될 수 있다.
그리고, 지지턱(71)은, 커버 가압단계(S30)에서 상부커버(10) 및 하부커버(20) 중 어느 하나 이상의 외측면을 가압하는 롤러(40)의 가압력을 지지할 수 있다.
특히, 지지턱(71)이 형성되면, 상술한 지지면(30)이 상부커버(10) 및 하부커버(20)의 테두리 단에 형성되지 않아도 된다.
그리고, 커버 융착단계(S40)는, 커버 조립단계(S20)에서 조립된 상부돌출턱(13)와 하부돌출턱(23)가 중간커버(60)와 맞닿는 접촉면 중 중간커버(60)의 삽입홈(61) 타측면과 맞닿는 접촉면을 레이저(50)로 융착시킨다.
