Description

Technical Field

[0001] The utility model relates to the technical field of punching and blanking dies, in particular to a punching and blanking die for a mounting plate. Background Art

[0002] Punching and blanking are two basic stamping processes in metal processing. Both belong to the category of blanking technology and are usually completed using special dies on a stamping machine. Punching refers to punching holes of the required shape and size on a metal plate or blank, removing part of the material, and the punched-out material (i.e. the material around the hole) is considered waste. Blanking refers to punching out parts of a predetermined shape and size from a larger plate or blank. This part of the punched-out material is the required product, and the remaining material becomes waste or remnant. Both processes require precise die design to ensure clear punching edges, accurate dimensions, and efficient processing.

[0003] In the actual stamping production process, many parts need to be blanked and punched. Often, they need to be blanked and punched in sequence through two types of dies, the blanking die and the punching die, to complete the processing of the parts. Due to multiple die switching and positioning, the precision control of each punching becomes a problem, which is prone to dimensional deviation, affecting the quality of the final product, increasing the scrap rate, and causing material waste and cost increase.
