Abstract
A method and a press are proposed for an energy-efficient drive of a press () with a bottom drive, in which a drive device () disposed in a bottom section (), a plunger () executing a stroke (H) and receiving an upper tool part () with at least one acting tie rod () of a drive train () are provided and the upper tool part () corresponding to a bottom tool part () disposed in the bottom section () machines or forms a work piece (). The drive device () is operated by at least one motor () and by way of a control and regulation device () connecting the motor () and the drive train (). Each drive train () can be operated by its own motor (). When using a drawing device with a holder (), it is operated in the change and during at least a partial path of the respective stroke (H) by the drive train () while observing a shaft-type free space () provided in the bottom section () in a coupled or decoupled manner by a releasable rotatory or translational active connection.
