The work aims to design a rotating bracket for automatic feeding with respect to the quality problem currently resulting from manual feeding in stamping production. The intermittent rotation of the bracket was controlled by the duty ratio and frequency of the output signal generated by the rectangular wave signal generator. The photoelectric sensor was applied to detect the stop position of rotating bracket to cooperate with the punch press to complete the automatic stamping of workpiece. The design could improve the existing manual processing method, save manpower and achieve the automatic operation of punch press production line. Such design provides reference value for automatic feeding on similar production lines.
