[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. This utility model, through the coordinated arrangement of a support base, I-beam base, rotating disk, hydraulic cylinder, fixed shaft, stamping equipment, positioning frame, clearance hole, support plate, feeding frame, guiding mechanism, and transmission mechanism, enables automatic feeding and automatic punching of chains. Specifically, the downward movement of the hydraulic cylinder's telescopic end causes the feeding frame to move downwards, driving the two second toothed plates. This, in turn, causes the toothed rod to rotate counterclockwise, moving the first toothed plate to the left. This pushes the chain in the feeding frame to the left onto the rotating disk until it is positioned within the positioning frame. This eliminates the need for frequent manual feeding, facilitating subsequent automatic punching and reducing the workload of personnel. Furthermore, while feeding the chain, the stamping equipment can simultaneously punch other chains. When the stamping equipment is lifted upwards, the feeding frame also moves upwards, ultimately causing the first toothed plate to automatically reset for subsequent automatic feeding.

[0015] 2. This utility model, through the coordinated design of the top-feeding mechanism and the linkage mechanism, eliminates the need for manual unloading. Simultaneously, the chain after punching is unloaded while the chain is being fed. At the same time, the stamping equipment also punches the chain below, completing a series of automated operations. Specifically, when the punched chain is rotated to the right by the turntable, the left end of the L-shaped rod aligns with the push plate. Subsequently, when the extension end of the hydraulic cylinder moves downward, it pushes the connecting rod downward, causing the bottom end of the connecting rod to move the L-shaped rod within the guide frame. Finally, the left end of the L-shaped rod pushes the push plate and the top rod, allowing the front end of the top rod to automatically push the punched chain within the positioning frame, unloading it automatically from the turntable without manual removal. This automates the chain punching process. Furthermore, when the extension end of the hydraulic cylinder moves upward, the L-shaped rod moves away from the push plate, causing the push plate to automatically reset, without affecting subsequent automatic feeding and punching processes.
