Patent ID: 8826715

Claim:
A forming device for cup-shaped hollow bodies comprising: a machine frame having a support plate, a support frame and supporting brackets, the support plate and the support frame forming a first machine frame section and the supporting brackets forming a second machine frame section; a rotatable turntable for supporting one of a plurality of workpiece hollow bodies or a plurality of machining tools; a linearly movable carrier for supporting the other of the plurality of workpiece hollow bodies or the plurality of machining tools, wherein the rotatable turntable and linearly movable carrier oppose one another, and wherein the rotatable turntable can be rotated in relation to the linearly movable carrier around an axis of rotation, and wherein the linearly movable carrier can be linearly displaced in relation to the rotatable carrier along the axis of rotation; a drive mechanism supported by the supporting brackets of the second machine frame section for providing a rotational stepping motion and a cyclical linear motion between the rotatable turntable and the linearly movable carrier, in order to allow the forming of the hollow bodies by means of the machining tools in a plurality of sequential machining steps; a stationary supporting tube disposed on the support plate of the first machine frame section, the stationary supporting tube having a central axis extending along the axis of rotation and supporting the linearly movable carrier; a guiding device disposed on an external surface of the supporting tube for mounting the linearly movable carrier with the cyclical linear motion; a rotary bearing disposed on the support plate of the first machine frame section for supporting the rotatable turntable, the rotary bearing being arranged with a spacing from the stationary supporting tube; and an articulated, flexible coupling area provided between the first machine frame section and the second machine frame section for substantially decoupling forces provided by the drive mechanism and the rotatable turntable and the linearly movable carrier.
