Punching Device

A punching device for cutting a workpiece to form a cutout portion, comprising:

• a base including a die part that has a top wall defining at least one die edge and adapted to support the cutout portion thereon;
• an abutting member connected to said base;
• a spring-biased punch supported on said base, movable relative to said die part and said abutting member between upper and lower positions, and having at least one blade edge, said blade edge being disposed above said die edge when said punch is disposed at the upper position, and being disposed below said die edge when said punch is disposed at the lower position, said blade edge being slidable toward said die edge for cutting the workpiece;
• and
• an ejecting unit supported on said base and including a non-compressible ejecting element disposed above and adjacent to said top wall of said die part, said punch being movable relative to said ejecting unit at least during movement of said punch from a middle position between the upper and lower positions, where said blade edge is substantially flush with said die edge, to the lower position, said ejecting unit abutting against said abutting member at least when said punch is disposed at the upper position so as to permit said ejecting element to eject the cutout portion of the workpiece, which is undesirably raised by said punch upon restoration of said punch from the lower position to the upper position, from said punch.
