The punching device can realize automatic feeding and punching by setting an automatic feeding and positioning mechanism. Generally, the feeding device and the punching die are used in conjunction with each other. When the size of the punching die changes, the position of the feeding mechanism needs to be changed to cooperate with the punching die to avoid the feeding mechanism being unable to feed the sheet into the punching die.

[0003] The defects of the existing stamping device are: 1. The prior art KR1020060092188A discloses a punching hole punching device, which does not have a structure for automatically feeding the plate and conveniently replacing the punching die. When it is necessary to replace the die of different sizes, the die and the feeding mechanism need to be re-matched, which is troublesome to operate. Therefore, a punching device with automatic feeding and positioning that is convenient for replacing the punching die and re-matching the feeding mechanism with the punching die is needed to solve this problem.

[0005] 3. The prior art KR1020110084095A discloses a punching device, which does not have a structure for removing burrs on the edge of a plate. When burrs exist on the edge of a plate, it is not convenient for the automatic correction mechanism to correct the plate, which may easily cause correction deviation. Therefore, a punching device with automatic feeding and positioning that can conveniently remove burrs on the edge of a plate is needed to solve this problem.

[0006] 4. The prior art CN114074446B discloses a punching device, which does not have a structure for removing the cut burrs. When the burrs on the edge of the plate are removed, the burrs are easy to enter the inside of the punching die, causing the plate to be unable to remain horizontal inside the punching die, affecting the punching effect of the plate. Therefore, a punching device with automatic feeding and positioning that can easily remove burrs from the plate and remove burr waste is needed to solve this problem. Summary of the invention

When there are burrs on the side of the rectangular plate, the cutter bent plate component 31 moves downward to cut off the burrs, and at the same time, the cutter bent plate component 31 moves along the edge of the rectangular plate to cut off the edge burrs of the rectangular plate in multiple times. After the cutter bent plate component 31 cuts off the burrs on the edge of the rectangular plate, the vacuum cleaner component 33 absorbs the waste, and then the cutter bent plate component 31 moves upward, the push plate 26 moves to the right, and at the same time the laser rangefinder 21 detects the position of the rectangular plate until the rectangular plate is moved into the punching die 10, and then the punching punch 15 moves downward to punch the rectangular plate, and the punching waste is discharged downward through the blanking port 11.
