Influence of Process Parameters on the Deep Cup-Drawing Process by Simulation

Abstract:

Cup drawing, besides its importance as forming process, also serves as a basic test for the sheet metal formability. To determine the optimum values of the process parameters, it is essential to find their influence on the deformation behaviour of the sheet metal. Based on the predicted thickness and stress distribution of the deep drawn circular cup and analysis of process parameters by LS-DYNA software in the paper, it is evident that the minimum thickness is at the punch radius, which was the danger zone for breaking. BHF is the main influence factor of a axi-symmetric cup, according drawing theory, the curve of the variable blankholder force (VBHF) we designed could improve the formability of sheet. Further, it is shown mold radius has the greater influence on the deep drawing of blank sheet.
