The invention relates to a multi-functional servo crank press and a working mode of the crank press. The multi-functional servo crank press comprises a crank press driven by an AC servo motor; a main servo control unit of the AC servo motor is respectively connected with a power network, an energy storage unit and a computer control system; the energy storage unit momentarily releases power to conduct stamping; the computer control system controls rotation angles, speeds and torques of the AC servo motor in real time according to a preset program so as to realize the optimal working mode; a brake is arranged on an output shaft of the AC servo motor and connected with the crank press through a reduction gearbox in a transmission way; an angle sensor and a displacement sensor are respectively arranged on a crankshaft and a machine bed of the crank press; the two sensors carry out real time detection for close height displacement of a slider and the angle of the crankshaft and feed back detected data signals to the computer control system so as to make corresponding adjustment. The multi-function servo crank press and the working mode of the crank press have a simple and reasonable structure and can truly realize diversified process, high precision, high efficiency, low energy consumption and low noise.
