| Abstract: | Taking advantage of the great properties of PVDF Piezoelectric-film such as thinness, high impact resistance and wide frequency range etc, this paper presented a male die monitoring method which could monitor slim male die` crack when punching. The monitoring method adopt a multi-point PVDF Piezoelectric-film transducer, a multi-point charge amplifier circuit and Microcontroller Unit. The multi-point PVDF transducer could be easily deployed in a die, and perceive blanking pressure directly; Special designed charge amplifier and Microcontroller-based architecture can lower the cost of monitoring greatly. Theoretical analysis and mimic experiment proved that this monitoring method could perform the function of male die monitoring. |
