Abstract

본 발명에서는 배력장치의 셀을 성형하는 제조방법은 두꺼운 금속의 판상소재를 여러회로 나누어서 프레스가공하여 밑부와 원통부와를 성형하는 성형공정과, 밑부와 동일의 두께를 갖는 원통부를 축방향으로 잡아 늘여서 해당 밑부 보다도 얇은 두께로 성형하는 아이어닝 공정과, 이 아이어닝 공정에 의하여 얇게된 원통부의 개구부측에 해당 원통부의 두께분 만큼 대경으로한 단이달린 대경부를 형성하는 대경부 성형공정과를 구비하고 있다.In the present invention, the manufacturing method for forming a cell of the power unit is a molding process of forming a bottom and a cylindrical portion by pressing a divided metal plate material of a plurality of times, and holding a cylindrical portion having the same thickness as the base in the axial direction An ironing step of forming a thinner thickness than the bottom part, and a large diameter part forming step of forming a large diameter part having a diameter with a diameter equal to the thickness of the cylindrical part on the opening side of the cylindrical part thinned by the ironing step; have.

그리고, 대경부 성형공정은 원통부의 개구부측을 확경한 데이퍼상 부분을 성형하는 예비성형 공정과, 그 확경한 데이퍼상 부분을 최종적으로 단이달린 대경부로 형성하는 본 성형공정으로 이루어져 있다.The large diameter portion forming step includes a preforming step of forming a tapered portion having a diameter of the cylindrical opening portion, and a main molding step of forming the enlarged tapered portion into a large diameter portion having a final stage.
