Description

Technical Field

[0001] The utility model relates to the field of blanking dies, in particular to a blanking die used for blanking reinforcing sheets. Background Art

[0002] With the development of social economy and the improvement of people's living standards, more and more products are being manufactured, many of which are made by molds. Molds are widely used in industrial production.

[0003] Molds are the various dies and tools used in industrial production to create desired products through methods such as injection molding, blow molding, extrusion, die-casting, forging, smelting, stamping, blanking, and hot pressing. Simply put, molds are tools used to create shaped objects. These tools are composed of various parts, and different molds are made up of different parts. They primarily shape the object by changing the physical state of the material being molded, and are often called the "mother of industry."

[0004] When producing FPC boards, some will set reinforcement sheets at the gold finger positions of the FPC boards to improve the mechanical strength and durability of the gold fingers, thereby extending the service life of the gold fingers. Therefore, the production process involves the punching operation of the reinforcement sheet strip.

[0005] Currently, the lower die of a punching die is generally fixed to the punching machine using a screw-locking method. This requires the use of a screwdriver to tighten multiple screws to secure the lower die. This operation is cumbersome, and for small-batch production, the lower die needs to be frequently replaced. This operation also requires a significant amount of time, resulting in increased labor hours, high production costs, and low work efficiency. This creates inconvenience for production and fails to meet current needs. Therefore, it is necessary to develop a new technical solution to address these issues. Utility Model Content
