FIELD: machine building. ^ SUBSTANCE: press bench consists of at least two force cross rails in the form of plates and at least two connecting support cross rails. Supports are located around the perimeter of cross rails; plane of column is perpendicular to the planes of cross rails. Supports have slots, located at the internal side of supports (relative to the bench centre). Force cross rails are fixed at these slots. Force rims of slot collars are straight, unloaded rims are sloped. Force cross rails are made with bevels at the area of contact with unloaded rims of slot collars. ^ EFFECT: enhancing the bench rigidity not increasing bench overall dimensions; simplification of assembly. ^ 12 cl, 6 dwg |
