경사면에 구멍이 있는 판재 부품의 프레스 드로잉에 관한 연구

Abstract

In this study, to create circular holes on an inclined conic face, we developed a novel process of verticalpiercing on the plane before drawing, instead of applying an expensive cam-piercing method. The piercedholes are deformed during the drawing, and their shapes are affected by the size of the center hole. Usingthe Abaqus CAE program, the deformation tendency of the holes, according to the diameter of the centerhole, was identified, and the diameter for securing the roundness of the side holes were determined throughactual experiments. The developed process was successfully applied to mass production of the part, and acost reduction is expected.
