Abstract
505,090. Extrusion dies. NORTHERN ALUMINIUM CO., Ltd., and PARRY, E. A. Nov. 2, 1937, No. 29959. [Class 87 (ii)] [Also in Group XXII] A die for the extruding or drawing of material with a polygonal cross-section comprises a body enclosing a plurality of plates 8 slidably arranged edge to edge, the two edges .9, 10 of each plate which abut on the adjoining plates, defining an acuteangle between them and one of said edges serving as one side of a polygonal area 12 of the desired shape, the plates being adjustable in a rotary sense about the axis of the die for moving the plates relatively to one another to vary the size of the die opening. In one form, Figs. 1 and 2, the plates are mounted within a body comprising a back 1, a ring 3 and a front cover 2 bolted together by - bolts 4. The ring 3 has six internal surfaces 5 through which project adjusting or guide screws 7 for the plates. Adjustment of the plates to vary the size of the die opening 12 is effected by means of screws 20. The plates may be clamped by means of bolts 14 passing through slots 15 and 16 in the back and front portions 1 and 2 and through slots 13 in the plates 8. In a modified form, Fig. 3, the cover portion 2 is angularly adjustable for effecting the movement of the plates. Pins 24 screwed into the cover 2 pass through slots 25 in the plates and into sliding collars which run in arc-shaped grooves in the back portion 1. The cover 2 is rotated by means of a hand wheel 33 and worm. 30. The working edges of the plates are provided with hard metal facings 22 secured by screws 23.
