Abstract
A forming device for cup-shaped hollow bodies, including a machine frame, a drive device, a workpiece turntable and a tool holder, wherein the drive device (15) is designed to provide a rotational step movement and a cyclic linear movement between the workpiece turntable and the tool holder, and wherein the workpiece turntable is assigned at a locking position a first actuating means for triggering a locking movement on the respective workpiece holder and at an unlocking position a second actuating means for triggering an unlocking movement on the respective workpiece holder. A third actuating means is arranged along a curved machining path for the hollow bodies between the locking position and the unlocking position so as to trigger a combined unlocking and locking movement on the respectively associated workpiece holder in order to at least partially unlock, optionally move and then lock once again the hollow body held in the respective workpiece holder during one cycle of the cyclic linear movement of the tool holder.
