Abstract

964,008. Forging. HYDRAULIC G.m.b.H. Jan. 2, 1961 [Feb. 11, 1960], No. 146/61. Heading B3H. Cast ingots 3c, particularly of aluminium, are pressed into blanks 3b for subsequent rolling, in an hydraulic press having oppositely movable platens 7a, 7b. The cast ingot 3c is fed stepwise by a pair of forge tongs 4, along a track formed by sets of rollers 2a-2e which are individually adjustable in height by double-acting hydraulic pistons 17c, Fig. 3 (not shown). The blank 3b emerging from the press is gripped by another pair of forge tongs 10 and drawn along an outgoing roller track formed by height adjustable rollers 9a-9f. Press platen 7b is mounted on a cross-head, 6b, Fig. 4, connected to one or more pistons 23 working in one or more cylinders 24 of a movable cross-head 22 connected by columns 21 to an upper cross-head 6a carrying the platen 7a. Pressure liquid admitted through pipes 25 to cylinders 24 causes the pistons 23 to rise and the cross-head 22 to fall. The movement of the two platens is synchronized by pistons 27a, 27b working in cylinders 26a, 26b interconnected by pipes 29. Retracting pistons 30 operate in cylinders 31. Heating means 8a, 8b, Fig. 2, are provided in the platens.
