Abstract

1,094,657. Extruding. LOEWY ENGINEERING CO. Ltd. Feb. 25, 1965 [March 19, 1964], No. 11701/64. Heading B3P. A metal extrusion press has a rotatable die carrier 12 mounted on an axis 14 and disposed between a fixed platen 2 and an axially movable billet container (6), and a plurality of retractable pivoted latches 30 adapted to anchor the carrier to the platen. The carrier has fork ends for receiving a pair of exchangeable dies 10. A pair of latches 30, Fig. 2 (not shown), are pivoted on axis 28 and actuated by fluid pressure units 32. The latches 30 have hooks (36) engaging behind shoulders (38) on the carrier 30. After extrusion the container (6) is withdrawn axially whilst the die 10 and its carrier 30 are held in place by the latches. A saw 50 then severs off the discard between the die and container. Alternatively the discard may be severed by a shear (41), Fig. 2 (not shown) whilst the die is supported by tongues (42) engaging the carrier 12. If the latches are released during withdrawal of the container, the product may be severed between the die 10 and bolster 18. The latter may be mounted on a slide or on a rotary arm. The latches 30 may alternatively be pivoted on the carrier 12 and engage shoulders on the platen 2.
