Claims

[Scope of utility model registration request]

A punching die for cutting a workpiece from a continuous thin plate material, one side of the front and rear edges having point symmetry itself and the opposite side having line symmetry therewith, the front and rear edges having rectangular shapes. a pair of lower cutting blades cut out in the center of at least one rectangular shape and provided to intersect with the upper surface of the lower mold body, and supported on a spring fixed to the lower mold body facing the lower cutting blades. A set of upper cutting blades, a cam supported on a spring also fixed to the lower mold body and alternately setting the upper cutting blades to the cutting position, and one feed from the intersection of the leading edge and trailing edge cutting blades. A feed-cutting die characterized in that it has a punch for punching out a notch-corresponding portion of the cutting blade in advance at a position before the pitch.
