<p>A machine tool having a machine frame open on three sides in the shape of the letter C, comprising an upper die support, disposed on the machine frame and vertically movable by a drive cradle, with at least two die holding fixtures placed side by side and having corresponding upper dies, a lower die support disposed on the machine frame with a corresponding number of die holding fixtures placed side by side and having corresponding lower dies, and a matrix plate clamped on the lower die support, disposed in a frame containing the die holding fixtures. In this configurement, it is possible to use a self-guided tool unit in an equally flexible manner as the normal upper and lower dies, by disposing, instead of a lower die, a tool unit comprising an upper die and a lower die contained in a guide frame, such as a cutting unit or a coping unit, on a matrix plate in a corresponding die holding fixture, and to drivingly couple it with the upper die support.</p> |
