[0029] Working principle: Place the workpiece to be stamped on the die 132, the fixed cylinder of the press drives the upper die base 113 to move downward, the upper wedge block 111 pushes the die 132 to move toward each other, the punch 112 contacts the die 132, and the stamping of the workpiece is completed. After stamping, the fixed cylinder of the press drives the upper die base 113 to move upward, the punch 112 and the upper wedge block 111 separate from the die 132, the telescopic spring 134 drives the die 132 to return to the initial position, and the driving cylinder 214 is started. On the one hand, the bracket 215 drives the brush 4 and the push plate 5 to move. During the movement, The brush 4 can clean up the waste chips on the die 132, and the pusher plate 5 can push the workpiece punched on the punch 112 down to achieve the purpose of automatic unloading and improve the unloading efficiency. On the other hand, the bracket 215 drives the connecting rod 212 to move, and the oil blocking plate 211 leaves the oil channel 223.
