TL;DR: In this paper, the influence of the die corner radius shape on wear behavior during sheet metal stamping was examined and the effect on tool life determined, and it was shown that small changes in die radius profile shape (of less than 15μm) can result in significantly reduced tool life.
Abstract: This paper investigates the influence of the die corner radius shape on wear behavior during sheet metal stamping. In particular, small and localized changes from an ideal circular die profile shape were examined and the effect on tool life determined. A novel technique to test and characterize the die profile shape and wear behavior, based on a semi-industrial channel forming process, is presented. It will be shown experimentally that small changes in die radius profile shape (of less than 15 μm) can result in significantly reduced tool life. In all cases examined, the small variations in shape were the result of inherent variations associated with the machining, grinding and polishing processes typically used to manufacture stamping dies and die corner inserts. Numerical simulation shows that these small shape ‘defects’ at the die corner radius can result in a significant increase in local contact pressures, explaining the large adverse changes in tool life. These results are of direct importance to stamping engineers and tool designers and indicate that careful control over die manufacture and maintenance procedures may result in significant improvements in tool life.

TL;DR: In this paper, a door intrusion beam is of laminated construction and has a base metal stamping with end flanges, with the base metal stamps being of an inverted generally U-shaped cross section.
Abstract: A door intrusion beam is of laminated construction and has a base metal stamping with end flanges, with the base metal stamping being of an inverted generally U-shaped cross section. Slidable and nested on the base metal stamping are a plurality of slidable and stackable elongated plastic elements each having a generally M-shaped configuration. The first plastic element next to the metal stamping and all stackable elongated plastic elements are secured together by layers of adhesives where surfaces contact one another. The plastic elements are of varying length.

TL;DR: In this article, a topology optimization method based on Solid Isotropic Microstructure with Penalty (SIMP) is proposed to reduce the weight of key die components, which can effectively reduce die weight and maintain the derived forming performance of stamped part.

TL;DR: In this paper, the formability of aluminium foam sandwich (AFS) panels was investigated through experiments and numerical simulations, and FEM analyses were developed using a porous material model following the evolution of the material density throughout the forming processes.
