Abstract

1,069,909. Work-holders; stamping. RHEINSTAHL WANHEIM G.m.b.H. Sept. 23, 1964 [Sept. 24, 1963], No. 38870/64. Headings B3B and B3Q. [Also in Divisions E1, F1 and F2] A mechanical force amplifying means, which is applied to an embossing or stamping press, Figs. 4 and 5 (not shown), a vice, Fig. 6 (not shown), and a chucking fixture for machine tools, Fig. 8 (not shown), comprises relatively rotatable pressure plates 1, 2 each formed with two concentric tracks inclined to a plane transverse to the axis, and balls or rollers located between corresponding tracks and extending 180 degrees therearound, the arrangement being such that on relative rotation of the plates 1, 2, relative axial movement of the plates 1, 2 also occurs. An intermediate pressure-plate 7, Fig. 3 (not shown), having balls on each side thereof may be arranged between plates 1, 2. When the top pressure-plate 1 has turned through one revolution, a dog 8 strikes a stop element 9 and entrains the central pressure-plate 7 during the next revolution. Locking means such as a freewheel ratchet may be provided to prevent backrunning of one disc under the applied pressure. On release of the locking means, the return to the original position may be assisted by spring means.
