SINGLE-COLUMN BED OF GAP FRAME PRESS Russian patent published in 1994 - IPC

FIELD: press-forging equipment. SUBSTANCE: single-column bed of gap frame press comprises column with closed box-shaped walls. Front side of outer cross sectional contour should be larger than, or equal to, press table width. Back side of column is smaller than the front one and is determined by the relation b₁/b₂≥ 2·(h/a)^3/2 where b₁,b₂ - front and back sides, h - cross sectional height, a - bed overhang. Internal cross sectional cavity is trapezoidal like the trapezium of external contour. Disposition of internal cavity is determined by the relation where Y_c2 - distance from press front to center of gravity of internal cavity; F_c - cross sectional area. EFFECT: improved design. 3 dwg, 1 tbl
