Description

Technical Field

[0001] The utility model relates to the technical field of FPC reinforcing plate processing, in particular to a stamping die for FPC reinforcing plates. Background Technique

[0002] The reinforcing plate is also called the strengthening plate, the reinforcing plate, the support plate, the strengthening plate, and the reinforcing rib. The reinforcing plate is mainly used in construction, oil pipelines, machinery equipment, electronic products, etc., and is widely used in FPC flexible circuit boards in electronic products. The reinforcing plate mainly solves the flexibility of the flexible circuit board, improves the strength of the plugging part, and facilitates the overall assembly of the product. In the processing of the FPC reinforcing plate, the stamping die is used for forming operations. For example, the Chinese patent discloses a stamping forming device for an FPC reinforcing plate (the authorization announcement number is CN216575076U). This patented technology can install or remove the next reinforcing plate while stamping the reinforcing plate, enabling it to perform assembly line operations, improving the stamping efficiency, and avoiding angular deviation between the reinforcing plate and the fixing plate when clamping the reinforcing plate, reducing the unqualified products generated during stamping, and at the same time making the template easy to disassemble and replace;

[0003] However, when the existing stamping die for FPC reinforcing plates is actually applied, there are still some defects that need to be improved. For example:

[0004] First of all, the FPC reinforcing plate after stamping is located inside the die, which is not conducive to the convenience of taking out the FPC reinforcing plate. Using tools for taking out operations, the FPC reinforcing plate is easily damaged during the taking out process, affecting the stamping forming quality;

[0005] Secondly, in order to ensure the smoothness of the FPC reinforcing plate after stamping, the material is often heated. If the material is not cooled in time after stamping, it will affect the processing efficiency, resulting in deformation of the taken-out FPC reinforcing plate, which is not conducive to the stamping forming effect. Therefore, those skilled in the art have provided a stamping die for FPC reinforcing plates to solve the problems raised in the above background technique. Content of the Utility Model
