Abstract
The springback of spherical parts in both integral-gripper and discrete-gripper stretch forming processes were investigated by using explicit-implicit algorithm. The effect on springback value and shape errors of pre-stretching, thickness and materials were studied. The simulation results show that springback and shape errors in the integral-gripper stretch forming are bigger than that in the discrete-gripper stretch forming; the springback gradually decrease and shape errors reduce as pre-strecthing increases, a prior pre-stretching is 1%; the springback and shape errors are gradually reduced as sheet metal gets thicker; the greater the elastic modulus and yield strength of the material, the smaller the springback and shape errors of the formed parts.
