Abstract

963,279. Billet piercing; extruding. YORKSHIRE IMPERIAL METALS Ltd., and J. H. CAIRNS. Oct. 16, 1962 [Oct. 20, 1961], No. 37681/61. Headings B3H and B3P. In the extrusion of metals, a billet 1 is pierced by a mandrel 6, 7 having a bore 13 through which a lubricant is fed during piercing. The mandrel has a detachable nose 6 providing escape channels for the lubricant which flows along annular passage 11. This lubricant may be solid, liquid and gaseous, e.g. air. After piercing, the billet is extruded by a ram 8, 9 through die 5. The detachable nose is removed from the mandrel stem by the extruded product, Fig. 8 (not shown), and cooling water, which may be mixed with soluble oil, is supplied through the bore 13. Limit switches are used to control the supply of lubricant and coolant. Reference is made to the extrusion of copper or copper base alloys.
