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.

Abstract: In a method and an apparatus for reducing the cutting impact in a hydraulically-driven precision blanking press, the force necessary to reduce the cutting impact as a counterforce is generated directly in the pressure chamber of the drive piston such that the counterforce acts directly on the cutting punch and so that the design of the press can be simplified, costs can be reduced, no additional external hydraulic-mechanical means for reducing the cutting impact are needed, and so that the loads on the press and the die can be reduced.

Abstract: In an apparatus and a method for controlling the primary drive of a hydraulically driven fine blanking press, the hydraulic circuit is simplified due to the elimination of hydraulic tubes, and the amount of hydraulic fluid is reduced, while increasing the number of strokes and achieving a simple design for the press.

Abstract: The invention relates to a precision blanking press including a top, a base and tie rods and columns that operatively connect the top and the base. The precision blanking press has a press frame with a high stiffness, low mass and simple design, the press allowing the transfer of higher cutting forces during fine blanking while safely eliminating axial play between adjustment elements and at the same time improving the operational safety.

Abstract: The invention relates to an apparatus and method for stripping away/pushing out a punched grid/internally formed part and ejecting a blanked part in a precision blanking press. The object of the invention is to provide 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, wherein the force of stripping/pushing out and ejection can be adjusted independent of the knife-edged ring force and the counterstay 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.

Abstract: The invention relates to a precision blanking press comprising a top, a base and tie rods and columns that connect the top and the base non-positively. The object of the invention is to provide a precision blanking press characterized by a press frame with a high stiffness, low mass and simple design, the press allowing the transfer of higher cutting forces during fine blanking while safely eliminating the axial play between the adjustment elements and at the same time improving the operational safety.
