Abstract
1,226,986. Extruding. WESTERN ELECTRIC CO. Inc. 4 July, 1968 [5 July, 1967], No. 31971/68. Heading B3P. An extrusion press has a rod-like ram 12 moved into a billet container 16 by a driven plate 33 slidable on bars 28 along which spaced plates 30-32 are also slidable with the ram extending through the plates so that bowing of the ram under load is prevented. The plate 33 is connected to three cylinders 22 and has notches around its periphery to engage the bars, Figs. 4 and 5 (not shown). The plates 30-32 are similarly notched and interconnected by bolts 51-53. The plates are formed with openings (55) to receive the bolt heads of the adjacent plate. Each plate is latched to one of the bars by a spring biased latch (83), Fig. 6 (not shown). The latch is cammed inwards upon movement of the plate. A rocker arm (87) is pivoted against spring bias from under the latch by the advancement of the preceding plate. In operation the plate 33 is advanced by the cylinders and picks up the other plates 30-32 in turn. The advancement of the ram causes the billet 14 to extrude through the die 18 and issue from the rear of the ram. The extrusion is facilitated by hydraulic pressure in the container 16.
