Abstract

A forming device for cup-shaped hollow bodies (7) having a machine frame (2), a drive device (15), a workpiece rotary table (3) and having a tool holder (4) for accommodating processing tools (10), wherein the workpiece rotary table (3) and the tool holder (4) face one another and can be turned about a rotational axis (5) in relation to one another and can be linearly moved in relation to one another along the rotational axis (5), wherein the drive device (15) is designed for providing a rotary step movement and a cyclical linear movement between workpiece rotary table (3) and tool holder (4), in order to enable the hollow bodies (7) to be formed by means of the processing tools (10) in a plurality of consecutive processing steps, and wherein the workpiece holder (6) has a recess (16) for accommodating a hollow body (7) and a wall section (42), which limits the recess (16) in certain areas, has an adjustable geometry, which is designed to narrow the cross-section of the recess (16), in order to enable the hollow body (7) to be fixed on the workpiece holder (6).
