CPC B30B 15/04 (2013.01) [B30B 15/281 (2013.01); B21J 13/04 (2013.01)] | 23 Claims |
1. 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.
