<p>For energy-efficient driving of a press (1) with an underneath drive, a method and a press are proposed, in which a driving device (2) which is arranged in a substructure (3) and a slide (1.1) which executes a stroke (H) and receives a tool upper part (1.2) are provided with at least one engaging connecting rod (2.1.2) of a drive train (2.1) and the tool upper part (1.2) which corresponds to a tool lower part (3.2) arranged in the substructure (3) machines or deforms a workpiece (5). The driving device (2) is operated by at least one motor (2.1.1) and via a control and regulating device (4) connecting motor (2.1.1) and drive train (2.1). Each drive train (2.1) can be operated by a dedicated motor (2.1.1). When a drawing device with a holder (3.3.1) is used, said holding device is operated in alternation by the drive train (2.1), with a shaft-like clearance (3.3.2) provided in the substructure (3) being maintained, by means of a releasable, rotatory or translatory operative connection and is coupled or decoupled during at least one partial displacement of the respective stroke (H).</p> |
