ONE-PIECE JOINT BODY CONSISTING OF SINTERED METAL

摘要

The invention relates to a method for producing a metal component, in particular an internal joint part (3) of a Cardan joint (1), which is provided with ball paths (7). According to the invention: a charge cavity (28) is filled with powder; the charge cavity (28) is delimited by means of a die (27), at least one moulding mandrel (22) and a charging mandrel (23) positioned opposite the latter, a central mandrel (26) and at least one lower and upper punch (24, 25); the powder is compressed in the charge cavity (28) by pressure on the upper and/or lower punch to form a green product, which is then expelled and sintered.
