A press brake, wherein the lower beam (3) and/or the upper beam (4), which are structural assemblies that can be assembled from separate parts, include a frame beam (9), wherein an edging tool can be supported on the horizontal edge (R) of a long side thereof. The lower beam (3) and/or the upper beam (4) include a force distribution system comprising at least one pair of oblique tensile bars (12, 13; 14, 15) connected by connections (20, 21, 23, 24, 25, 26, 27, 28, 31, 33, 36, 38) that form force node points relative to the frame beam (9) and adapted to transmit and distribute a press force provided by press cylinders (5, 7) to the desired locations determined by the locations of the connections in the desired power distribution ratio throughout the edging length of the frame beam (9) in order to keep the edge (R) of the frame beam straight. |
