[0022] Working principle: During use, first set the control program through the PLC controller 4, then use external force to pull the handle 46 upward, the movement of the handle 46 drives the slide bar 44 and the weight block 45 to move upward until the top of the weight block 45 is close to the inner top of the support frame 43, and then place the raw material body 41 inside the storage bin 40. After the raw material body 41 is placed, remove the pulling force applied to the handle 46. After losing the pulling force, the weight block 45 falls downward to the top of the raw material body 41 under the action of gravity, exerting downward pressure on the raw material body 41, and then the stamping operation can be started through the PLC controller 4; During the stamping operation, the PLC controller 4 controls the air pump 34 to start, and at the same time, the PLC controller 4 controls the second servo motor 28 to start loading. The driving end of the second servo motor 28 drives the power rotating shaft 29 to rotate. The rotation of the power rotating shaft 29 drives the first bevel gear 30 to rotate. The rotating first bevel gear 30 drives the second bevel gear 33 to rotate, thereby driving the transmission shaft 31 and the circular gear 32 to rotate. The rotating circular gear 32 pushes the loading push plate 22 to slide inside the loading trough 42 through the gear guide rail 23 and pushes the raw material body 41 located at the bottom to move. When the raw material body 41 moves to the outside of the storage bin 40, the top end of the loading push plate 22 supports the raw material body 41 inside the storage bin 40. When the raw material body 41 moves to the top of the stamping lower mold 25 and is close to the outside of the adjusting baffle 16, the PLC controller 4 controls the second servo motor 28 starts to retreat, and the driving end of the second servo motor 28 drives the power rotating shaft 29 to rotate in the opposite direction, thereby indirectly driving the loading push plate 22 to return to the initial position. When the top end of the loading push plate 22 is separated from the bottom end of the raw material body 41 inside the storage bin 40, the raw material body 41 inside the storage bin 40 falls downward to the bottom under the pressure applied by the weight block 45. At the same time, the PLC controller 4 controls the punching machine 5 to start the punching operation. When the punching die end of the punching machine 5 moves downward to the top end of the raw material body 41, it squeezes the raw material body 41 for punching and forming. When the punching die end of the punching machine 5 is inserted into the inner side of the punching groove 26, the punching is completed. At this time, the PLC controller 4 controls the punching machine 5 to move its punching die end upward to the initial position. At this time, the raw material body 41 is punched into a waste body 18 and a finished product body 19, and the finished product body 19 is located on the inner side of the punching groove 26. After stamping, the PLC controller 4 controls the first servo motor 14 to start the waste diversion. The driving end of the first servo motor 14 drives the distribution plate 8 to rotate to the side close to the finished product discharge slot 9. At the same time, the PLC controller 4 controls the solenoid valve 36 to open for 1 second. The airflow generated by the air pump 34 is transported to the inside of the flat nozzle 37 through the connecting pipe 35 and discharged through the air jet 38. The airflow impacts the outside of the waste body 18 and pushes the waste body 18 to move to the inside of the receiving slot 6. It falls to the inner bottom end of the receiving slot 6 under the obstruction of the receiving baffle 7. Under the diversion effect of the distribution plate 8, the waste body 18 is discharged to the inside of the waste collection box 12 through the waste discharge slot 10. Then the PLC controller 4 controls the first servo motor 14 to start the finished product diversion. The driving end of the first servo motor 14 drives the distribution plate 8 to rotate. The finished product body 19 is moved to the side close to the waste discharge groove 10, and the PLC controller 4 controls the electric push rod 13 to extend. The telescopic end of the electric push rod 13 pushes the sliding discharge block 27 to move upward. The movement of the sliding discharge block 27 pushes the finished product body 19 located on the inner side of the stamping groove 26 to move upward. When the sliding discharge block 27 moves to the top higher than the top of the stamping lower die 25, the PLC controller 4 controls the solenoid valve 36 to open for 1 second. At this time, the airflow pushes the finished product body 19 located at the top of the sliding discharge block 27 to the inner side of the receiving groove 6 and enters the waste discharge groove 10 through the guide of the distribution plate 8. The finished product body 19 is discharged to the inside of the waste collection box 12 through the waste discharge groove 10. At the same time, the airflow discharged through the air jet 38 cleans up the debris generated by the stamping, and then continues the cyclic stamping operation.
