After the clamp cylinder works to control the two clamps to hold the workpiece, the clamp cylinder stops; then the feeding cylinder works to send the workpiece to the feeding position. At this time, the feeding position electromagnetic switch controls the feeding cylinder to stop. At the same time, the punching and bulging tool punches the workpiece; after the punching is completed, the feeding cylinder retreats until the material picking position electromagnetic switch senses in place, controls the feeding cylinder to stop, the clamp cylinder retreats, and the manipulator takes out the processed workpiece to realize the next round of operation.
