Design and Application of a Novel Cone-shaped Blank Holder for Precision Stamping Process
2015
Procedia CIRP
In this paper, a novel cone-shaped blank holder for precision stamping process is presented. The aim is to achieve a variable blank holder force (VBHF) during large axial symmetry parts precision stamping process. The blank holder is designed as a combination of a segmental upper blank holder which is divided into several areas in radial direction and a lower blank holder with a continuous lower surface, and the lower binder is designed as an elastically deformable plate which is able to adjust
