Patent ID: 8132441

Claim:
A device for fine blanking and forming a workpiece from a flat strip through several machining steps, the device comprising: an upper part, including punches and/or a forming element and an upper pressure plate for the punches and/or the forming element that defines V-shaped projections thereon, each of the punches and/or forming element and upper pressure plate serving as effective elements of the upper part; a lower part, including effective elements comprising a cutting die, an ejector, a forming anvil and a lower pressure plate; the flat strip being clamped between said upper pressure plate defining V-shaped projections carried thereon and said lower part when closed, and movable in a feeding direction in an open state of said upper and lower parts in one machining cycle including blanking, fine blanking, preforming and/or punching; the cutting die being formed as a disc-shaped transfer part with several cutting openings respectively paired with one or more of the effective elements, which takes up and clamps a cut out blank, to transport the cut out blank from one machining stage to a next machining stage, the transfer part being turnable with regard to the effective elements of the upper part around a virtual axis in a center of the transfer part and parallel to a machining direction, turnable perpendicular to the virtual axis after being lifted over the effective elements of the lower part comprising a respective cutting opening of the cutting die, the ejector and the forming anvil, and the cutting openings in the transfer part being arranged on a common base circle, a radius of said common base circle coinciding with a distance of the machining stage to the virtual axis; and machining stages of the upper part being arranged on the common base circle at fixed distances to each other, and machining stages in the transfer part being allocated at least two locking bolts diametrically opposed at the circumference, fixed in the pressure pad of the upper part, the locking bolts being arranged parallel to the virtual axis and several of said locking bolts being arranged diametrically opposed at respective circumference locking openings in the transfer part for adjusting, fixing and lining up the effective elements of the upper and lower parts to each other.
