박판의 온간 2차원 드로오 벤딩에서의 스프링백
Springback for the Warm 2D Draw-bending of Steel Sheets
초록
The purpose of this study is to investigate the characteristics of springback for various process conditions of the 2D draw-bending operation. The process variables are the forming temperature, the geometry of tools such as punch profile radius(Rp) and die profile radius(Rd). Especially, in order to control the springback, the use of the warm forming method is applied. For the warm draw-bending, five steps of temperature ranges, from room temperature to
