Abstract:
The deep drawing process cylindrical cups require several steps. If you can reduce step the
deep drawing cost of production, mold cost reduction and It can also be used to know the deep
drawing , as well as the basic information that can be used to determine the appropriate variables.this
study the Influence of Punch-Die clearance on formability of Deep Draw Process and the Influence of
die shape ๓ type include tractrix, radius and oval respectively.The sheet metal material to JIS SPCC
standard. with thickness ๓ mm. Initial diameter is ๔๕ mm. Success diameter is ๓๒ mm. The results of
the simulation and the experiment showed that when the Punch-Die clearance increased, the deep
drawing was very and height of the cup is higher than the Punch-Die clearance with little value the workpiece thickness has not changed. this behavior will be beneficial for the deep drawing in the next.
however, the punch-die clearance is too high, the cup height is reduced and the cup shape is difficult
to control. At the same time the design of the tractrix die shape is higher than oval and radius.
Comparing the simulation results and the experiments tended to be consistent with past research
