Procedure and device for the manufacture of annular and rotationally symmetrical work pieces from metal and / or ceramic powder using metal and / or ceramic powders and a laser beam |
| abstract |
Procedure for the manufacture of rings or cores in the form of a pot as rotationally symmetrical work pieces from hard metal powder and / or ceramic for dies for tools for solid shaping for powder pressing, where a support core (3 ) or a spike-shaped element (9) with at least one support core (8) is fixed in a rotating tension device (2) and is rotated, the support core (3.8) consists of resistant material at high temperatures and it has at least one segment (4), whose external diameter corresponds to the internal diameter of the ring or core (5) to be manufactured or is slightly smaller, and in a defined distance to the tension device (2) on the surface circumferential of the support core (3,8) that have different external diameter diameters, in which a different layer structure is made in the thickness of the wall, the metal powder is melted by a laser head and / or ceramic and is applied in layers until the final wall thickness of the workpiece blank is configured, where the laser head is moved from one side to the other and through channels (6) that overlap the structure of The workpiece in layers of the matrix core (5) as a primary forming process, and once the support core has been cooled (3.8), is partially or completely removed from the workpiece blank and the piece works mechanically on its inner and / or outer side to the desired size |
