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.

Method for operating a press with an underneath drive and press operated according thereto

The present invention provides a method for operating a press which includes providing a press with at least one plunger which executed a stroke, an upper tool part, a sub-structure. A control and regulation device receives a value(s) on an operating condition from a system of the press. The value(s) are provided from the system of the press to the control and regulation device during a processing of a work piece. The value(s) provided are processed to the control and regulation device according to a function under the condition that so as to permanently operate a movement of the plunger via a drive device and the press in a controlled manner or in a regulated manner according to a system of forces required for a work piece with a respective force which is actively influenced or is actively modified in a position and a dimension/amount.
