A Study of Hole Flanging-Upsetting Process

Abstract:

A combined process of hole flanging and flange upsetting was proposed. Both elastic-plastic FEM and experiments were employed to analyze the process. A 2mm thick 08AL sheet with 120mm outer diameter and 24.6mm center hole diameter was used as the blank. The effect of the R_f and the R_c values on the flanging quality were analyzed, where R_f was defined as the ratio of the die fillet size to the workpiece thickness t and R_c was defined as the ratio of the clearance C to the workpiece thickness t. Also the effect of R_f and R_c on upsetting ratio R_u which was defined as the ratio of thickness before and after upsetting were studied. The finite element results were validated by experimental results. Also a 2mm thick flange without thinning and defects was gained in a reasonable range of R_c and a certain value of R_f.
