Hydroforming을 위한 Tie-bar의 예비굽힘성형 해석
강대철,전병희,성부용 한국공작기계학회 2000 한국공작기계학회 추계학술대회논문집 Vol.2000 No.-
Tube bending is one of the conventional manufacturing process. Recently, tube bending was highlighted in automotive industry by hydroforming. Tube hydroforming process is divided into pre-bending process and hydroforming process. It's initial state is very important in die cavity of first hydroforming process. So tube bending is important factor of the hydroforming process. In this paper, two pre-bending simulations, by a rotary draw bending machine and a bend die. This paper presents the simulation results in pre-bending process that is used to form an automotive part, tie-bar.
