Shaping Device, in Particular a Spindle Press, and Method for Shaping Workpieces

A spindle press, comprising:

• a) a processing head, having several different processing tools, that is guided in a movable manner along a movement axis (MS) for the forming processing of at least one workpiece;
• wherein:
• b) the spindle press comprises a slide, and the processing head is formed on or attached to the slide, and
• c) a processing region, located opposite the processing head, having at least one processing station configured for the forming processing of the workpiece, and furthermore comprising:
• d) a rotary table having an axis of rotation (MD) parallel to the direction of movement and several lower dies that are arranged, with respect to the axis of rotation (MD), in an offset manner with respect to one another in the circumferential direction, wherein:
• e) the rotary table is configured and mounted in a rotatable manner such that each of the lower dies is transferable by rotation of the rotary table into at least one first working position located within the processing region and into at least one, second working position which is located at least partially laterally outside a cross-sectional area (Q) of the processing head in axial projection with respect to the axis of movement (MS), wherein:
• f) an angular spacing of the lower dies on the rotary table is such that it is possible for forming steps to be carried out at least partially parallel in time, and wherein
• g) the processing tools are arranged such that it is possible for forming operations which require comparatively high forming forces to be carried out in the region of the slide center, and for forming operations with comparatively low forming forces to be carried out in regions located further away from the slide center.

A method for the forming processing of a workpiece with a spindle press, the steps comprising:

• a) transferring a lower die of a rotary table into at least one second working position, located laterally outside a cross-sectional area (Q) of a processing head, by rotating the rotary table about its axis of rotation (MD);
• b) inserting a workpiece into the lower die located in the at least second working position;
• c) rotating the rotary table about its axis of rotation (MD) such that the workpiece is transferred from the second working position into at least one first working position;
• d) activating the processing head for the forming processing of the workpiece;
• e) optionally rotating the rotary table about its axis of rotation (MD) and transferring the workpiece into a further first working position;
• f) transferring the workpiece into the second working position, or into a further second working position located laterally outside the cross-sectional area of the processing head;
• and
• g) removing the workpiece from the lower die located in the second or further second working position, wherein
• h) forming operations which require comparatively high forming forces are carried out in the region of a slide center, and forming operations with comparatively low forming forces are carried out in regions further away from the slide center.
