Abstract

The invention relates to a drawing press (10) having a first ram (17) and a second ram (18). The first ram (17) is moved in a working direction (A) by an electromotive first ram drive (25) and the second ram (18) by an electromotive second ram drive. The drawing press (10) also has a coupling means (35) which can be switched between an uncoupling state and a coupling state. In the uncoupling state, the two rams (17), (18) can move independently of one another in the working direction (A). In the coupling state, the coupling means (35) ensures that a relative movement between the two rams (17, 18) is prevented. The drawing press (10) can therefore be operated as a single-acting or double -acting press.
