[0063] As an embodiment of the present invention, the pusher assembly includes:

[0064] A mounting plate 29 is provided on the plurality of support rods 8. Specifically, four support rods 8 are provided on one side of the upper surface of the base 1, and the mounting plate 29 is provided on the four support rods 8;

[0065] The electric push rod 27 is horizontally arranged on the mounting plate 29;

[0066] The push plate 28 is arranged on the telescopic end of the electric push rod 27 , and the push plate 28 can push the sheet material on the support plate 12 in a direction away from the electric push rod 27 .

[0067] As an embodiment of the present invention, a pair of baffles 13 are provided on the top of the support plate 12, and the pair of baffles 13 are arranged parallel to the upper surface of the support plate 12. The gap between the pair of baffles 13 matches the width of the sheet to be punched, and the pair of baffles 13 are used to limit the sheet on the support plate 12 when it moves horizontally to prevent the sheet from shifting when it moves horizontally.

[0068] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0069] The working principle and use process of the utility model are as follows: when in use, first, the positions of the multiple sets of reset assemblies are adjusted according to the requirements of punching holes in the sheet material, so that a set of punching rods 20 that meet the punching requirements are moved to the bottom of the multiple push rods 26. The specific adjustment method is: start the motor 4 arranged in the through slot 1-1, the output shaft of the motor 4 drives the connected screw 5 to rotate, and the screw 5 drives the screw 5 nut connected by thread to move in the through slot 1-1. When the screw 5 nut moves, it drives the connected transmission rod 7 to slide horizontally in the slide slot 1-2. When the transmission rod 7 moves, it drives the connected lower cover 10 to slide on the upper surface of the base 1. When the lower cover 10 moves, it drives the support plate 12 at its top to move, and the support plate 12 drives the concave plate 14 and a pair of baffles 13 at its top to move. When the concave plate 14 moves, it drives the multiple sets of reset assemblies arranged thereon to move horizontally, and the multiple sets of reset assemblies drive the multiple punching rods 20 to move, thereby making the multiple punching rods 20 that meet the punching requirements move to the bottom of the multiple push rods 26;

[0070] Secondly, the sheet material is placed on the support plate 12 through the loading device so that the sheet material is located between the push plate 28 and the hydraulic rod 24. The loading device is preferably a manipulator, which starts the electric push rod 27 provided on the mounting plate 29. The telescopic end of the electric push rod 27 extends out to drive the push plate 28 to move toward the side of the concave plate 14. The push plate 28 pushes the part of the sheet material to be punched to the bottom of the multiple punching rods 20. When the push plate 28 moves horizontally on the support plate 12, a pair of stop bars 13 can limit its two sides to prevent the push rod from deflecting when it moves.

[0071] Again, a pair of hydraulic rods 24 arranged at the bottom of the top plate 9 is started, and the telescopic ends of the pair of hydraulic rods 24 extend to drive the connected second movable plate 25 to move vertically downward. The second movable plate 25 drives the multiple push rods 26 arranged at the bottom to move vertically downward, so that each push rod 26 is embedded in the first through hole 14-1 opened on the concave plate 14 and pressed down to the top of the first movable plate 19, so that the first movable plate 19 moves vertically downward. When the first movable plate 19 moves, the slider 18 moves vertically downward in the limit groove 15-1. When the slider 18 moves, the first telescopic rod 16 and the first spring 17 are compressed. When the first movable plate 19 moves, it also drives the impact The pressing rod 20, a pair of second telescopic rods 21 and a pair of second springs 22 move vertically downward, and the pair of second telescopic rods 21 and the pair of second springs 22 drive the pressing plate 23 set at the bottom to move. When the pressing plate 23 is pressed onto the upper surface of the sheet material to fix the sheet material, the first movable plate 19 and the punching rod 20 continue to move downward. At this time, the second telescopic rod 21 and the second spring 22 contract. When the punching rod 20 is embedded in the second through hole 23-1 and continues to move downward, the sheet material is punched. The metal sheet at the punching position enters the lower cover 10 through the punching hole 12-1, and the metal sheet slides on the inclined plate 11 and slides out from the opening side of the lower cover 10.

[0072] Finally, after the stamping is completed, the telescopic end of the hydraulic rod 24 contracts, causing the push rod 26 to move vertically upward. Under the elastic force of the first spring 17 and the second spring 22, the first movable plate 19 and the pressure plate 23 return to their initial positions. At this time, the electric push rod 27 is started again. The electric push rod 27 causes the sheet to slide on the support plate 12, so that the next position to be punched is located below the push rod 26. Repeat the above steps to perform the punching process. After the punching of the sheet is completed, the electric push rod 27 pushes a part of the sheet to the outside of the concave plate 14, and then the sheet is taken away by a blanking device (such as a robot).

[0073] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
