20110193257	Method for Producing a Molded Part Provided with a Through-Hole - To produce a molded part with a through-hole, a rod-shaped blank is pushed through a guide into a cavity and fixed in place. The end region of the blank is compressed and reshaped into a disk. A disk core having the same cross-sectional shape as the blank is ejected out of the disk using a punch and pushed into the guide and moved back together with the unshaped part of the blank. The disk is severed from the disk core and the molded part is removed from the cavity. During the penetration step, the disk present in the cavity is subjected to an axial pressure in the disk core ejection direction and the blank is subjected to an axial counter-force opposite to the disk core ejection direction.	08-11-2011
20100253107	WORKPIECE TRANSPORT DEVICE - A workpiece transport device for a forming machine includes at least one gripping tongs, which has two non-crossing gripper arms that are pivotable with respect to one another, where the arms each have a gripping end for gripping a workpiece. Each of the two gripper arms are articulated at ends opposite from the gripping end on a common guide head and, in a middle region between the two ends, and on its own link bar. The two link bars are each rotatable about a fixed pivot, wherein the fixed pivot of the link bar of one gripper arm is arranged closer to the other gripper arm than is the fixed pivot of the link bar of the other gripper arm.	10-07-2010
