Abstract：

Relationship and control of axis sealing and internal pressure directly affects deformation process in tube hydroforming.Combining computer imitation curve with specific tube and equipment parts,we got the time-voltage curve and chose the hydraulic component to control them.It gives a reference for the experiment.
