ABSTRACT:
A coining press is provided with a machine frame, a coining drive for slides and coining dies, an ejector coining die against which the coining die can be pressed with the interposition of the coining blank and can partially yield for this purpose, a drive for the ejector movement of the ejector coining die and one device respectively for feeding the coining blank and for removing the finished coined part. The coining drive has a coupling dwell gear which is hinged to a toggle joint gear. The coupling dwell gear has a connecting rod moved by an eccentric shaft, the longitudinal axis of the connecting rod extending substantially in parallel to the coining plane and the end of the connecting rod facing away from the coining die being hinged to a booster device. The toggle joint gear has three pressure lugs which, on one end respectively, are hinged to one another on a pin while the end of a first pressure lug is hinged to the connecting rod. The other end of a lower pressure lug is hinged to the machine frame while the other end of an upper pressure lug is hinged to the slide.
