For a cylinder-beam integrated hydraulic press (CCIHP) 6300 kN, its hydraulic cylinder is a hemispherical shell and used as an upper beam. It is the key structural component that outputs the driving force to form parts. Compared the traditional three-beam and four-column hydraulic press with a cylindrical hydraulic cylinder, the structure and force distribution were significantly different from CCIHP. Therefore, the total weight could be reduced and the nominal force could be increased. The cylinder-beam integrated structure, the stress distribution and deformation deflection of movable beam and lower beam were analyzed by numerical simulation. The results show that the peak value of equivalent stresses for cylinder-beam integrated structure, moving beam and lower beam are 70.0, 54.4 and 141.5 MPa respectively，and the maximum deformation deflections are 0.16, 0.10 and 0.15 mm·m-1 respectively. Therefore, both strength and stiffness for the body structure of cylinder-beam integrated hydraulic press meet the design requirements, and the equivalent stress and deformation deflection under the full load are within acceptable range.
