Abstract
1,274,930. Swaging machines. MASCHINENFABRIK SACK G.m.b.H. 26 Nov., 1969 [2 Dec., 1968; 11 Dec., 1968; 17 Jan., 1969], No. 57915/69. Addition to 1,144,845. Heading B3H. [Also in Division E2] A swaging machine has four dies 1-4 which are mounted and interact as in Specification 1,144,845 and the pivots 19-22 for the guide arms 15-18 of the dies are mounted in pairs on a pair of slides 24, 25 so that neighbouring pairs can be equally adjusted. The slides are moved by screws 38, 39 against hydraulic rams 40, 41. Both or one slide may be moved to cause the dies to produce a rectangular cross-section workpiece 23. The cylinders 6-9 for the rams 10-13 which move the dies may be pivoted to the machine frame or the joint between the ram and an integral die and arm 15-18, Fig. 3, is made doubly articulate (see Divisions E1-E2). The joint is lubricated during the return stroke and the initial part of the forward stroke. The dies are returned by separate hydraulic units 51-54. The dies 1-4 may be mounted on the arms 15- 18 by overload devices. These devices may be tension bolts (114), Fig. 5 (not shown), shear pins or limit switches or strain gauges which stop the drive to the die on overload. The workpiece is fed stepwise through the dies and is hot.
