Abstract

1,065,443. Cutting-out presses. HAMMERLE A.G. MASCHINENFABRIK. Aug. 4, 1964 [Sept. 12, 1963], No. 31236/64. Heading B4B. In an hydraulically-operable cutting-out press in which the press beam is operable on both sides by pistons 33, a pressure transmitter 8 is provided between a low-pressure pump 2 and the pistons, the transmitter at the same time effecting the parallel control of the pistons, i.e. so that during its movement the press beam remains parallel to the press bed. The transmitter comprises two pistons 14, 17 of different diameters working in chambers 12, 13, four high-pressure pistons 21 coming to bear against the larger piston 17, the pistons 21 being divided into two groups each acting on one of the pistons 33. The chambers 12, 13 are connected with one another through a conduit 281, 28<SP>11</SP> which is subject to an interrupter element formed as a change-over valve 26 which is under the influence of a precontrol valve 27 operable by an end switch of the press beam or by a pressure switch. Adjust. able stops 34 serve for adjustment of the correct press beam position.
