Abstract
1,080,557. Forging. E. RIBBACK. Nov. 23, 1964 [Nov. 21, 1963; Feb. 25, 1964], No. 47522/64. Heading B3H. [Also in Division B5] In an hydraulic press having forming cheeks 3 supported by the shorter arms 2 of levers pivoted at 1, the longer arms 4 of these levers enclose an operating piston 5 and cylinder 6. In one example (Fig. 1) four double-armed levers are pivoted on axes 1 (see Fig. 2, not shown), the levers being urged together by springs 11. The piston 5 carries rollers 9 which engage wedges 7 on the lever arms 4. The wedges on one pair of arms may be arranged further from the pivots than the wedges on the other pair, so that one pair of cheeks 3 may be used to deform the end of a tube into an " eight " whilst the other pair " folds " the tube (see Fig. 2, not shown). In another example (Fig. 3, not shown) the piston acts on the levers through pivoted linkage (14, 15).
