Deep drawing process is one of the widely used methods in sheet-metal forming. With the deep drawing method, products of various geometrical shapes such as saucepans, tubes, perfume and soft drink cans can be obtained easily. Therefore, the optimization of the deep drawing process is very important for the industry. In conventional deep drawing method, no angle is given to the surfaces of die a...

In this paper, unique tests into the production of galvanised steel wires in industrial conditions were presented. It was demonstrated that three phenomena occur during wire-drawing process at high speeds: namely, zinc sticking to surface drawing drums, coating grinding caused by a larger friction area between tool and material, combined with detachment calibrating part die until wire breaks is...

in this paper, formation of wrinkling in bimetal deep drawing process has been investigated by the analytical, numerical and experimental methods. the effects of width of flange, fillet radii of matrix and punch, clearance of blank holder, contact conditions and relative thickness of two sheets on the number and height of wrinkle waves are studied. clearance and contact conditions have the grea...
