Web1. Abstract Circular cup drawing is the first forming process for forming the body of two-piece aluminum beverage cans / bottles. This paper has investigated optimum drawing process by changing circumferentially the blank holder forces, to draw earless circular cups from anisotropic blank sheet. At first, a drawing process analysis model has been made … WebThe simulation of drawing process was conducted for anisotropic AA3105 aluminum alloy sheet. Cup height (earing profile) and thickness distribution were obtained from experiments and corresponding numerical simulations. Comparison of these results demonstrates great potential of BBC2003 yield criterion in accurate prediction of earing.
WebIn the present study, we propose a novel method of varying blank holding force (BHF) with the segmental blank holder and investigated its influence on the earing reduction in the circular deep drawing process of an aluminum alloy sheet. Based on the analysis of cup height profile, the principle of varying BHF using segmental blank holder was presented … WebThe simulation of drawing process was conducted for anisotropic AA3105 aluminum alloy sheet.
