ABSTRACT:
A transfer device is provided particularly for multistation presses and is arranged between two working stations. The transfer device has a suction bridge which extends transversely with respect to a transfer direction and which is guided on its ends by two control arm gearings synchronously along a predetermined transfer curve. The control arm gearings are formed by control arms or rods which are connected on the end side with the cross traverse and which, on their respective end situated away from the cross traverse 46, are held in preferably vertically aligned linear axles, in which case the control arms, in respective pairs, enclose the same angle with one another. By the targeted controlling of the linear axles, almost arbitrary transfer curves can be travelled within the scope of the range of the transfer device. All linear axles are directly supported on a stationary frame whereby a high stiffness and precision is achieved even at high accelerations.
