With the development of production and the continuous emergence of new materials , new technologies forming process and forming an endless stream , the traditional mechanical presses can not meet the production process and use requirements. Studied in this paper a new generation of forming equipment - AC servo press , not only with the traditional mechanical presses precision, high speed , etc., but also to improve its working mode is fixed , single- motion characteristics , processes and poor applicability to manufacturing processing brings higher flexibility space . Through this analysis, a more comprehensive understanding of foreign advanced technology for our own development, design , optimize press equipment for reference. Based on Japan's Komatsu H1F type 80t main performance parameters of the servo press , through the rational allocation of transmission ratio , to design its transmission structure , the use of UG and CAXA software to build a model of the various components presses . Through the transmission mechanism kinematics and dynamics calculations to obtain the movement of the ram and punch crank input torque and pressure dependence equations. Meanwhile , the use of dynamic analysis software ADAMS to simulate the drive mechanism analysis, the movement of the slider force curve and the key points of each member of the instantaneous kinetic curve , in order to give the press process , the force and the zero parts kinetic energy distribution . The UG model into ANSYS software, the press frame for the finite element analysis . In the press Nominal force, the force identified danger point rack position , draw frame equivalent stress and deformation cloud . Finally, the press racks modal analysis, the rack in the given boundary conditions corresponding to the natural frequencies and mode shapes and shapes with a detailed analysis , to avoid the press in normal operation the reliability of the resonance and rack design provide a reference .
