[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention allows the storage tray to move along the front and rear end sides of the tray through the movement of the slide rail and the tray, thereby changing the position of the storage tray and facilitating the removal of the storage tray for centralized processing of the waste collected in the storage tray. Alternatively, the storage tray is placed on the end side of the slide rail, and the tray cavity of the storage tray is used to collect the waste falling through the discharge port, thereby achieving the purpose of integrated waste collection. At the same time, the cylinder operates to push the punch head upward, so that the punch head is close to the punching tray to perform punching processing on the skeleton blank.

[0016] 2. The present invention drives the transmission wheel to rotate through the operation of the transmission motor, and the belt drives two adjacent transmission wheels to rotate synchronously. When a sheet-like skeleton blank is placed on the upper end of the transmission wheel, the skeleton blank is driven, so that the blank is driven and transmitted along the horizontal direction of the main frame, thereby achieving the effect of conveying the blank. At the same time, the fan runs, and the air flow is circulated along the air cavity, the air delivery port, the air duct, and the frame air port, and finally ejected from the frame air hole. The inner frame rotates through the frame axis to adjust the direction of the inner frame, so that the direction of the frame air hole of the inner frame is adjusted, so that the frame air hole faces the end side of the punch head, so that the end wall of the blank is blown and cleaned when the punch head end side is punched, thereby achieving the purpose of removing impurities on the end wall of the blank and preventing impurities from affecting the forming effect during stamping.

[0017] The two driven gears are connected with the top side ends of the two stamping discs respectively to form a cam rotation state, so that when the driven gears rotate, the two stamping discs rotate alternately to the center area of the main frame. When one of the stamping discs rotates to the center area of the main frame, the punching head moves up, pushes the aggregate blank up, close to the stamping disc, and punches the blank through the stamping disc and the punching head. The punched broken material is placed in the stamping port. After the stamping is completed, the punching head moves down, causing the blank to fall down, and the side end wall of the blank falls on the transmission wheel. The blank displacement is transmitted through the transmission wheel. At the same time, the stamping disc rotates and moves away from the center area of the main frame. The spring column in the stamping disc pushes the slide plate to move down, driving the ejector rod to move down, and the waste material punched out in the stamping port is ejected and discharged. At this time, the other stamping disc rotates to the center area of the main frame again for stamping. BRIEF DESCRIPTION OF THE DRAWINGS

The transmission motor 10 runs, driving the transmission wheel 12 to rotate, and the belt 13 drives two adjacent transmission wheels. The driving wheel 12 rotates synchronously. When a sheet-like skeleton blank is placed on the upper end of the driving wheel 12, the skeleton blank is driven, so that the blank is driven and conveyed along the horizontal direction of the main frame 1, thereby achieving the effect of conveying the blank. At the same time, the fan 16 runs, and the air flow is circulated along the air cavity 14, the air delivery port 15, the air duct 17, and the frame air port 21, and finally ejected from the frame air hole 22. The inner frame 19 rotates through the frame shaft 20, and the direction of the inner frame 19 is adjusted so that the direction of the frame air hole 22 of the inner frame 19 is adjusted so that the frame air hole 22 faces the end side of the punch head 9, so that the end wall of the blank is blown clean when the punch head 9 is punching, thereby achieving the purpose of removing impurities on the end wall of the blank and preventing impurities from affecting the forming effect during stamping;

[0030] The driving motor 23 is driven by the main gear 24 and the slave gear 25, and the main gear 24 and the slave gear 25 are both connected to the main frame 1 in rotation. The slave gear 25 and the stamping disk 26 are fixedly connected, and the stamping disk 26 forms a sliding structure with the slide plate 28 through the disk sliding cavity 27, and the slide plate 28 forms an elastic structure with the stamping disk 26 through the spring column 29, and the slide plate 28 and the push rod 30 are fixedly connected. When the driving motor 23 runs, the main gear 24 is driven to rotate, and the main gear 24 drives the slave gear 25 to rotate. The rotation of the slave gear 25 drives the stamping disk 26 to rotate. The two slave gears 25 are respectively connected to the top side ends of the two stamping disks 26 to form a cam rotation state. When the slave gear 25 rotates, the two stamping disks 26 rotate alternately. Move to the center area of the main frame 1. When one of the punching disks 26 rotates to the center area of the main frame 1, the punching head 9 moves up, pushes the aggregate blank up, and approaches the punching disk 26. The blank is punched through the punching disk 26 and the punching head 9, and the punched broken material is placed in the punching port 31. After the punching is completed, the punching head 9 moves down, causing the blank to fall down, and the side end wall of the blank falls on the transmission wheel 12. The blank displacement is transmitted through the transmission wheel 12. At the same time, the punching disk 26 rotates and moves away from the center area of the main frame 1.

Near the punching plate 26, the blank is punched through the punching plate 26 and the punching head 9, and the punched-out broken material is placed in the punching port 31. After the punching is completed, the punching head 9 moves downward, causing the blank to fall, and the side end wall of the blank falls on the transmission wheel 12. The blank displacement is transmitted through the transmission wheel 12. At the same time, the punching plate 26 rotates and moves away from the central area of the main frame 1. The spring column 29 in the punching plate 26 pushes the slide plate 28 to move downward, driving the ejector rod 30 to move downward, and the waste material punched out in the punching port 31 is ejected and discharged. At this time, another punching plate 26 rotates to the central area of the main frame 1 and the punching process is performed again.
