Abstract (en)
[origin: WO9425260A1] In a press-driven tool module, in particular press-driven cross-punching or bending unit, a tool (18) mountable on a slide (9) is movable in any direction against the action of a restoring, integrated pneumatic spring, and the tool (18) carrying slide (9) may be actuated by a vertically movable press slide (17). For that purpose, a vertically guided plunger (23) arranged in a power cylinder (K) may be actuated by the press slide (17) by means of a piston rod (3) and acts upon a hydraulic medium (M) in an underlying displacement chamber (24). The displacement chamber (24) is connected by a high pressure pipe (25) to the work chamber (22) of a working cylinder (A) whose piston rod (9) bears the tool. In a preferred embodiment, the power cylinder (K) and the working cylinder (A) may be mounted apart from each other and linked to each other by a flexible high pressure pipe.
