Method and device for producing a hard metal compact and carbide compact

摘要

The present disclosure relates to a method and apparatus for producing a cemented carbide compact and a cemented carbide compact. The method comprises the steps of: providing a multi-part die (46) comprising: feeding at least one frontal molding (54, 56) movable in a first plane; Feeding at least one transverse molding (64, 66) movable in a second plane; Locking the at least one frontal molding (54, 56) and the at least one transverse molding (64, 66) to define a cavity (48) for a compact (10), wherein feeding directions of the at least one frontal molding (54, 56) and the at least a transverse molding (64, 66) are oriented obliquely to each other, preferably perpendicular to each other, wherein the at least one frontal molding (54, 56) and the at least one transverse molding (64, 66) surfaces (30, 32) of the compact (10) define, and wherein the resulting cavity (48) has at least one opening (50) through which a punch (74, 76) is insertable; Feeding a filling shoe (132) via an opening (50) of the cavity (48) and filling the cavity (48) with a hard metal powder; and compacting the powder with at least one punch (74, 76) which is movable in parallel to a main pressing direction (Z), the feeding of the at least one transverse shaped part (64, 66) along a feeding direction (104, 106) parallel to Main pressing direction (Z) is.
