[0037] The working principle and usage process of this invention: When in use, the user places the metal mesh belt on the detachable lower template 240. At this time, the metal mesh belt is cut and stamped in one piece by the cooperation of the stamping press 4 and the movable upper mold 5. When the movable upper mold 5 moves up and resets, the stamped metal filter screen (hereinafter referred to as the workpiece) remains at the bottom of the movable upper mold 5. When the stamping press 4 retracts and moves the movable upper mold 5 up by a certain distance, the movable transmission plate 3 abuts against the adjustable transmission plate 226. As the stamping press 4 further retracts, the movable transmission plate 3 moves up and drives the limit transmission plate 225 to move up. The upward movement of the limit transmission plate 225 drives the adjustable support plate 221 to move upward.

[0038] The adjustable support plate 221 is moved upward to lift the adjustable lifting plate 243 and move it above the detachable lower template 240. Then, as the stamper 4 further retracts, the limiting mounting plate 228, together with the elastic stripper 229, peels off the workpiece stuck on the movable upper mold 5. Due to the lifting effect of the adjustable support plate 243, the peeled workpiece cannot fall into the interior of the detachable lower template 240, thereby achieving fast and reliable stripping of the workpiece. Then, the stamper 4 is controlled to extend so that the movable upper mold 5 moves down to reset. At this time, the stripping assembly 22 is reset to its initial form.

[0039] Through the coordinated operation of multiple structures, the stamping device can automatically unload the workpiece stuck on the movable upper mold 5, and prevent the detached material from falling into the interior of the detachable lower mold 240. This eliminates the need for manual unloading by the user, making the stamping device not only time-saving and labor-saving, but also safer. Secondly, the modular design of this invention allows the stamping device to be quickly adapted to the stamping processing of different types of metal filter screens, thus broadening its application range. In addition, this invention has a simple structure, is easy to use, has low cost, and a low failure rate, making it worthy of promotion and use.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
