Abstract
In an apparatus and a method for stripping/pushing out a punched grid and for ejecting a blanked part from a die in a precision blanking press, the force of stripping/pushing out and ejection can be adjusted independent of the knife-edged ring force and the counterstay counteracting force while reducing the mass of the knife-edged ring and counterstay pistons, increasing the stripping/pushing and ejection speeds, and at the same time simplifying the hydraulic circuit.
