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.

Abstract: A method and an arrangement are used for transmitting data, signals and/or energy from stationary parts in or on metal-forming machines, particularly presses and/or stamping machines, or the environment to at least one sliding table and/or the transfer system of the metal-forming machine. For this purpose, a stationary device is provided as well as a movable device which complements the stationary device. The stationary device comprises at least one transmitter, a first coupler, a coupling loop, and a first antenna. The movable device, in each case, has at least one second transmitter and a second antenna. The stationary device and/or the movable device are arranged on base plates in this case.

Abstract: In the case of transfer presses and similar metal-forming machines, transfer devices must be provided for the transport of the sheet metal parts through the metal-forming stages. The lifting and lowering movement should be freely programmable, yet, a drive for the lifting and lowering movement is to be permitted which is free from play. This is achieved by the use of servo motors or similar motors with a hollow-shaft rotor and high-resolution position generators for the direct application on the transfer device, in which case the hollow-shaft rotor of each of the servo motors is provided with a spindle nut which, interacts with a spindle which is fastened on the transfer device in a non-rotatable manner.
