ABSTRACT:
A machine tool, in particular a machine for working with punches and dies parts formed from sheet material, comprises an essentially C-shaped frame made up of two parallel-connected, essentially C-shaped frame parts. The first frame part is designed to absorb the reaction forces from forces exerted by tools placed between the arms of the C-shaped parts. The second frame part is designed to hold the tools in a desired position relative to each other. The two C-shaped frame parts near the ends of the arms thereof are connected to each other only by means of a hinge joint between the bottom arm of the first C-shaped frame part and the neighboring bottom arm of the second C-shaped frame part, and a connecting element which at one side is hingedly connected to the top arm of the first C-shaped frame part by means of a hinge joint and at the other side is connected to the top arm of the second C-shaped frame part. The frame parts are connected in such a way that said connecting element can be moved in the working direction of the tools. The axes of the hinge joints are essentially at right angles to the principal plane of the C-shaped frame part, and intersect the common axis of tools placed between the arms of the C-shaped frame parts.
