[0003] In order to avoid the formed workpiece from being defective due to insufficient raw materials, the amount of raw materials required for most workpieces is generally used for processing, so that after processing, the edges of the workpiece will form some corner materials, which need to be cut off. Generally, after processing is completed, the excess part of the workpiece edge is cut off by blanking and trimming to obtain a qualified workpiece.

[0004] However, the current blanking and trimming die does not have an edge material stripping mechanism, and generally relies on the edge material to naturally fall off after blanking. If the edge material does not automatically demold, it is easy to cause material blockage / double material phenomenon during the next processing. Currently, in order to avoid the occurrence of these phenomena, manual stripping is mostly used. If high-frequency manual stripping actions are performed, the production rhythm will be reduced, and the tooling may be damaged to varying degrees and high maintenance costs may be caused. SUMMARY
