Optimization of flat forming with the use of draw beads and finite elements method

Abstract

Paper concerns shape and properties choice of draw beads in flange area at stamping drawing to achieve stamping dimensions according to drawing. In paper the simulation of stamping drawing process with various variants of draw beads is described together with evaluation of drawing results with the use of analyses of stamping drawability. For calculations and simulations the programmes of AutoForm 4.06 and PAM-STAMP 2G TM using finite elements method were used. The choice of shape and properties of draw beads to be used in serial production is described. In the end of paper the comparison of dimensions of stamping gained by simulations with the dimensions of real stamping which were gained by 3D measurement is carried out.
