METHOD AND DEVICE FOR PRODUCING A HARD-METAL PRESSED ARTICLE, AND HARD-METAL PRESSED ARTICLE

摘要

A method for the manufacture of a hard-metal pressed article comprises providing a multi-part die, involving: feeding at least one frontal mold part that is movable in a first plane; feeding at least one transverse mold part that is movable in a second plane; and locking the at least one frontal mold part and the at least one transverse mold part to define a cavity for a pressed article. Feed directions of the at least one frontal mold part and the at least one transverse mold part are inclined to one another. The at least one frontal mold part and the at least one transverse mold part define surfaces of the pressed article. The resulting cavity comprises at least one opening through which a punch is insertable. The method further comprises feeding a filling shoe above an opening of the cavity and filling the cavity with a hard-metal powder; and compressing the powder with at least one punch that is movable parallel to a main pressing direction. The feeding of the at least one transverse mold part takes place along a feed direction that is parallel to the main pressing direction.
