A stamping station is formed at the position opposite to the stamping slider 3 on the guide rail 20. The plurality of stamping sliders 3 can be synchronously driven to move by the main driving mechanism.

[0035] The unloading mechanism is located above one end of the guide rail 20. The unloading mechanism specifically includes a hopper, a plurality of unloading knives 41 located below the hopper, and an unloading drive mechanism that drives the unloading knives 41 to move. Among them: the hopper includes a plurality of guide rods 40 extending up and down, and the product is placed between the plurality of guide rods 40, as shown in the figure, taking four as an example. A spiral groove 410 is provided on the outer peripheral surface of the unloading knife 41, and the number of unloading knives 41 is preferably three. The unloading knife 41 is located above one end of the guide rail 20, and the product falls onto the guide rail 20 from the hopper through the unloading knife 41. The unloading drive mechanism includes an unloading cylinder 42, an unloading rack 43 connected to the unloading cylinder 42, and a plurality of unloading gears 44 connected to the unloading rack 43, and each unloading knife 41 is connected to a unloading gear 44.
