Abstract
Numerical simulations of drawing and redrawing thin sheets to form cylindrical elements, are complicated. It is mainly because of the problem with defining finite elements in the complex calculation model. This type of simulation requires creating a rheological model of material which includes a forming limit curve, a true-stress-strain curve and anisotropy defined in various directions. What is more, it is necessary to design an optimal geometry of tools. FEM calculations were performed for 3XXX series aluminum tape in cold-worked temper. To carry out the simulation, some crucial parameters mast have been defined, such as: the initial data, boundary conditions, as well as technological data concerning the sheets which were specified experimentally. Numerical analysis of thin aluminum sheet drawing and redrawing was carried out on 3 various sheet thicknesses, i.e.: 0,250 mm , 0,240 mm , 0,230 mm. Currently, the industry uses mainly sheets of 0.250 mm thickness. A few manufacturers of beverage cans use sheets of 0.240mm thickness while the sheet of 0.230 mm thickness is an innovation which manufacturers are trying to introduce into the industry to minimize the amount of material needed for production. For agiven thickness, the clearance between a punch and a die was calculated, as well as an optimum hold-down force. The influence of sheet thickness on the distribution of thinning of a wall was examined. In order to determine the minimal thickness of a sheet which allows to obtain the optimal thickness of the final product, the thinning of a drawpiece was analyzed. Moreover, the values of strains were compared to FLC curve. The intensity of stresses generated in a bottom and on side walls of a cup was also examined. © (2015) Trans Tech Publications, Switzerland.
