Abstract
1,236,846. Moulding tubes from metal powder. HENRY WIGGIN & CO., Ltd. 22 Aug., 1969 [29 Aug., 1968], No. 42039/69. Heading B5A. [Also in Division C7] A tubular compact of metal powder is formed by filling a tubular space in a mould with a mass of the powder, and radially compressing the powder by relative movement between the mould and a tapered mandrel introduced into the hollow core of the mass. As shown, the mould comprises a two-part cylinder 10 closed at its ends by expansible rubber seals 16, 18 through which the mandrel passes and end caps 17, 19 which support the seals. The mould is lined by a longitudinally split liner 21 and an expansible sleeve 22 extends axially through the mould between the seals 16, 18. The mandrel comprises a straight section 11 which is in the mould when the mould is filled with powder, a tapering section 12 and a sizing bar 13. The mould may be vibrated by vibrator 26 and the mandrel is preferably rotated as it moves through the powder. The slope of the tapered mandrel is between 0À33 and 10À4% (0À04- 1.25 inches per foot), the compact preferably has a length to wall thickness ratio of at least 5:1 and the wall thickness is reduced by 10-40%, preferably 20-30% by the compression. The metal powder may be nickel, cobalt, iron, copper, aluminium, magnesium, nickel-copper alloy or nickel-chromium alloy and may include metal compounds such as thorium oxide, magnesium oxide, aluminium oxide, silicon carbide and tungsten carbide. The compact may be sintered in or after removal from the mould.
