For the hydroforming of cylindrical part for 2219 aluminum alloy, the influences of die parameters on springback were investigated, and the hydroforming process was simulated by software ABAQUS IMPLICIT. Then, the pre-bulging pressure and forming pressure were given by adopting solid elements and 1/32 sheet model with different punch radius, die radius and clearance between punch and die, and the stress distribution and springback were simulated. On the basis of this, the changes of springback with the die parameters were given. The simulation results show that the springback of cylindrical part decreases with the increasing of punch radius, and with the increasing of die radius, the springback angle in 

the bottom of cylindrical part decreases,and the springback at the end of die radius in flange area slightly increases. Furthermore,the springback angle in the bottom of cylindrical part increases with the increasing of the clearance  between punch and die, and the influence of clearance between punch and die on the springback at the end of die radius in flange area is little.
