System of a frame for presses

A system of a frame for presses, comprising a press frame (1) having structural units constructed as at least two uprights (2), an upper cross connection with a head piece (3), and a lower cross connection (4) with a press table (4), the frame (1) forming a closed and releasably joined frame that receives static and dynamic forces of the presses, wherein

• a) the at least two uprights (2) each having a respective length (L) are manufactured as a structural unit and joined in abutment laterally or longitudinally to the cross-connections (3, 4) by way of non-positive joining geometries or non-positive and positive joining geometries (5) and releasable connectors (5.1) without tie rods,
• b) the at least two uprights (2) are subjected to tensile stress under an operating force (Fp) of the presses, and
• c) at least one of the two uprights (2) has a structure designed different from that of the other one of the uprights such that it deforms symmetrically under the operating force introduced asymmetrically into the uprights (2), and has cross-sectional regions differentiated commensurate with acting press forces such that at least one cross section of the upright (2) is constructed in sections in an open or closed and/or asymmetrical shape.
