A sort of reconfigurable combination driving device—reconfigurable bulging puncher is proposed

and the puzzle of reconfiguration of workpiece location

formed element’s female die and support cylinder position adjustment to different rim is solved. Fluid-solid coupling dynamic characteristics are researched on the basis of the finite element model. Considering the work condition of bulging and punching

the dynamic characteristics of coupling system is studied

and the result provided the theory basis for system dynamic characteristics optimization.
