[0024] First, by starting the servo motor 2 16, the servo motor 2 16 drives the connecting rod 1 14 to rotate the angle through the connecting rod 2 15. At this time, the connecting rod 14 drives the linkage plate 11 and the suction cup 904 to move left and right. Then start the feeding mechanism 9. At this time, the feeding mechanism 9 moves forward and backward and up and down, so that the feeding mechanism 9 can move in multiple directions, which is beneficial for the feeding mechanism 9 to load and unload the raw materials at the same time and avoid manual loading and unloading, thereby improving production efficiency. Secondly, start the cylinder 4. At this time, the cylinder 4 drives the lifting plate 5 to move up and down inside the mounting frame 3, so that the lifting plate 5 drives the punching die 7 to punch. Finally, if the punching die 7 needs to be disassembled, start the quick disassembly mechanism 6 at this time, so that the quick disassembly mechanism 6 leaves the inside of the punching die 7, which is beneficial for automatic quick disassembly of the punching die 7 and convenient for the staff to change the die.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the quick disassembly mechanism 6 includes an insertion strip 601, a gear 602, a rotating rod 603 and a servo motor 1 604. The output end of the servo motor 1 604 is fixedly connected to the top of the rotating rod 603, and the outer walls of the two rotating rods 603 are respectively fixedly connected to the inside of the two gears 602. The insertion strip 601 is respectively meshed with the two gears 602, and the insertion strip 601 is located on the opposite sides of the two gears 602.

[0026] When the punching die 7 is to be disassembled, the servo motor 604 is started, so that the servo motor 604 drives the gear 602 to rotate through the rotating rod 603. Since the two gears 602 are meshed with the inserting strip 601, the gear 602 drives the inserting strip 601 to move inside the mounting block 13, thereby making the inserting strip 601 leave the inside of the punching die 7, which is conducive to automatic and rapid disassembly of the punching die 7 and convenient for the staff to change the die.

[0027] like Figure 1 and Figure 5As shown, the feeding mechanism 9 includes a hydraulic cylinder 901, a movable plate 902, an electric push rod 903 and a suction cup 904, the output end of the hydraulic cylinder 901 is fixedly connected to one end of the movable plate 902, the top end of the electric push rod 903 is fixedly connected to the bottom end of the movable plate 902, and the output end of the electric push rod 903 is fixedly connected to the top end of the suction cup 904 through a connecting shaft, one end of the hydraulic cylinder 901 is fixedly connected to one side of the linkage plate 11, one end of the linkage plate 11 is movably connected to a connecting rod 14 through a rotating shaft, one end of the connecting rod 14 is movably connected to a connecting rod 2 15 through a rotating shaft, and one end of the connecting rod 2 15 is fixedly connected to a servo motor 2 16, and one end of the servo motor 2 16 is fixedly connected to one side of the support plate 8.

[0028] By starting the servo motor 16, the servo motor 16 drives the connecting rod 14 to rotate through the connecting rod 2 15. At this time, the connecting rod 14 drives the linkage plate 11 and the suction cup 904 to move left and right. Then the hydraulic cylinder 901 is started. At this time, the hydraulic cylinder 901 drives the suction cup 904 to move forward and backward through the moving plate 902. Then the electric push rod 903 is started. At this time, the electric push rod 903 drives the suction cup 904 to move up and down, thereby allowing the suction cup 904 to move in multiple directions, which is beneficial for the suction cup 904 to load and unload raw materials at the same time and avoid manual loading and unloading, thereby improving production efficiency.

[0029] Working principle: First, by starting the servo motor 16, the servo motor 16 drives the connecting rod 14 to rotate through the connecting rod 15, and the connecting rod 14 drives the linkage plate 11 and the suction cup 904 to move left and right. Then, the hydraulic cylinder 901 is started. At this time, the hydraulic cylinder 901 drives the suction cup 904 to move forward and backward through the moving plate 902, and then the electric push rod 903 is started. At this time, the electric push rod 903 drives the suction cup 904 to move up and down, so that the suction cup 904 can move in multiple directions, so that the suction cup 904 can load and unload the raw materials at the same time. Secondly, start The cylinder 4 is moved, and the cylinder 4 drives the lifting plate 5 to move up and down inside the mounting frame 3, thereby the lifting plate 5 drives the punching die 7 to perform the punching work. Finally, if the punching die 7 needs to be disassembled, the servo motor 604 is started at this time, so that the servo motor 604 drives the gear 602 to rotate through the rotating rod 603. Since the two gears 602 are meshed with the insert 601, the gear 602 drives the insert 601 to move inside the mounting block 13, thereby making the insert 601 leave the inside of the punching die 7, thereby quickly changing the die of the punching die 7.
