Deep Drawing Press Process
Deep drawing press process is quite challenging task to simulate due to requirement of multiple stages & precious tool design.Deep drawing is a sheet forming operation, in which the sheet is placed over the dieopening and is pushed by punch into the opening.The sheet is held flat on the die surface by using a blank. deep drawing press process In the deep drawing process, the blank-holding force (BHF) is an important process parameter affecting the energy consumption and the successful production of parts. In the present work, both experiments and finite element simulations have been conducted to investigate the influence of constant and time variable BHF on drawing force(DF) and thickness distribution in the deep drawing process of cylindrical and square cups.A finite element model was developed in the AutoForm software and validated with experiments. The developed model has been used for the simulation of deep drawing process of AA6016-T4 aluminum alloy sheet. The experiment...
