Claims (3)
- 소재를 연속적으로 공급하여 소정간격으로 절단구멍을 천공하고 이를 일직선상으로 공급하여 산과 골을 가진 파형판으로 절곡성형한 다음 파형판을 겹층으로 말아 감으면서 다층나선관을 성형하고 성형된 다층나선관에 있는 절단구멍 부분을 절단하는 방법으로 다층나선관을 얻게되는 다층나선관의 성형방법.
- 권취상태의 띠금속판 소재를 연속적으로 공급하는 공급부(10)와, 띠금속판 소재에 소정간격으로 절단구멍을 형성하는 천공부(20)와, 소재의 공급간격 및 공급시기에 맞게 조절하여 일직선상으로 공급하는 공급조정부(30)와, 소재를 나선관으로 성형할 수 있게 파형판으로 절곡성형하는 파형성형부(40)와, 파형판을 투입하여 성형롤에 의해 파형판이 자연적으로 1피치씩 이동하고 겹층으로 둘러말리면서 다층나선관으로 만들어지는 나선관 성형부(50)로 이루어진 다층나선관의 성형장치.
- 제2항에 있어서, 나선관성형부(50)는; 파형판 진입위치에 투입안내판(50a)을 설치하고 그 후방에 산(51a)과 골(51b)을 소정간격으로 형성한 성형안내롤(51)과 성형안내롤(51)의 바로 위쪽에 성형보조롤(52)을 배치하고 나선관 둘레에 해당하는 원주곡면상에 산(53a)과 골(53b)을 소정간격으로 형성한 감김안내롤(53)을 배치하고 원주곡면상에 절단칼(55)을 설치하여서된 다층나선관의 성형장치.
