Numerical Simulation of Square Cup Deep-Drawing Process under the Different Constraint Degrees Condition
In this paper, numerical simulation of square cup deep-drawing process under the different constraint degrees condition was investigated by means of advanced analysis software Dynaform5.5. The influence of different constraint degrees on the forming quality were analyzed by taking the inflow volume while parts forming 120mm as standard. The results showed that the effect of the uneven flow and deformation of metal have become bigger and bigger with the increase of constraint degrees. The rounded area at the bottom of square cup is no longer the most easy broke location, and the thickness of long side reduce little and uniform than other place.
