A forming device for cup-shaped hollow bodies (56) having a machine frame (2), a drive device (6), a workpiece rotary table (3) for accommodating hollow bodies (56) and a tool holder (4) for accommodating processing tools (58), wherein workpiece rotary table (3) and 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), and wherein the drive device (6) comprises first drive means (20) for providing a rotary step movement and second drive means (7, 8) for providing a cyclical linear movement between workpiece rotary table (3) and tool holder (4), in order to enable the hollow bodies (56) to be formed by means of the processing tools (58) in a plurality of consecutive processing steps. The second drive means has a stroke adjustment arrangement (8, 11, 70) which is designed for adjusting a working stroke of the cyclical linear movement as a function of a control signal of a control device (80) and/or for continuously variably adjusting the working stroke.
A forming device for cup-shaped hollow bodies having a machine frame, a drive device, a workpiece rotary table for accommodating hollow bodies and a tool holder for accommodating processing tools, wherein the workpiece rotary table and tool holder face one another and can be turned about a rotational axis in relation to one another and can be linearly moved in relation to one another along the rotational axis, and wherein the drive device comprises first drive means for providing a rotary step movement and second drive means for providing a cyclical linear movement between the workpiece rotary table and tool holder, in order to enable the hollow bodies to be formed by means of the processing tools in a plurality of consecutive processing steps, wherein the second drive means comprise a stroke adjustment arrangement which is designed for adjusting a working stroke of the cyclical linear movement as a function of a control signal of a control device and/or for continuously variably adjusting the working stroke.
A method for setting a phase position between first drive means which are designed for providing a rotary step movement and second drive means, which are designed for providing a cyclical linear movement for a forming device for cup-shaped hollow bodies, wherein between the first and the second drive means a first coupling device is arranged for intermittently suspending a forced coupling between the drive means, and wherein the second drive means are designed as a crank gear having a double eccentric arrangement for adjusting the stroke of the cyclical linear movement and having a drive motor which is coupled to the crank gear, the method comprising the steps of:
