<p>The invention relates to a tool for compacting the surface of a component (2) produced by powder metallurgy, comprising a mold (1) and a stamp (20), wherein in the mold (1) a recess (5) is provided which extends from a first mold opening (6) to a second mold opening (8), and which has a wall surface (10) for supporting the component (2), and the stamp (20) has a stamp length (23) and a stamp surface (21), wherein the inner diameter (12) of the recess (5) of the mold (1) becomes smaller from the first mold opening (6) in the direction of the second mold opening (8) or an external diameter (22) of the stamp (20) becomes greater over the stamp length (23), and wherein a compaction element (17) is arranged on the wall surface (10) of the mold (1) or on the stamp surface (21). The compaction element (17) is configured to have a thread-like progression.</p> |
