This paper introduces the structure of the hydraulic press for the tube plate composite internal high pressure forming hydraulic press. Using the finite element analysis software,the mechanical properties of the hydraulic press under two different process movements are analyzed. The stress and shape of the hydraulic press in the tube-sheet composite internal high pressure forming conditions are studied,and two kinds of operation work are guaranteed. The strength and stiffness of the press meet the design requirements. The research methods and results provide guidance and reference for the structural design of tubesheet composite hydroforming machine.
