For mechanical servo fine-blanking machine driven by two motors with multi-link mechanism, the main punching force during the press working section comes from the motor linked with the short crank, and the speed regulation during the rapid upward and return stage mainly depends on another motor linked with the long crank. It′s necessary to make sure the two motors corporate well that each motor has reasonable torque and the fine-blanking machine can work periodically. Therefove, a control strategy was carried out: with the phase feedback of the two cranks, switch motor speed curve at characteristic phase, and set the speed-regulation motor at zero speed station to make sure that the two motors can corporate well. The result of the simulation based on Adams and Simulink shows that the proposed strategy can effectively realize the normal periodic operation of the fine-blanking machine and the rational torque distribution of the two motors.
