Abstract

1,016,679. Angular bending. G. SALVAGNINI. Oct. 30, 1962 [Nov. 3, 1961], No. 41089/62. Heading B3E. A press brake is operated by two hydraulic jacks which are controlled, to keep the bending member level, by means, carried by a transverse member guided during descent of the bending member to remain level, co-operating with elements rigidly secured to the bending member. A bending plate 2 is lowered by two jacks 3 supplied with pressure liquid from two pumps 7, the flow to the jacks 3 being controlled by valves 11 carried by a transverse member 12 guided to remain parallel to the press base 1 during descent of the plate 2. The member 12 is supported by rods 17 rigid with the plate 2, heads 18 of the rods 17 controlling flow through the valves 11. The transverse member 12 may comprise a cylindrical body 19, Fig. 2 (not shown), carrying the valves 13 on bearings 29 and adapted to roll on a fixed upright 20. Tapes 21, 24 fixed at one end to the upright 20 and at the other end to the roller 19 ensure that the roller 19 remains level during its descent. One pump 7 may supply both jacks 3.
