As the sintered part (2) is moved, the surface is compacted from the first die orifice (6) to the last die portion (9) by die portions (7, 8, 9) continuously merging into one another and by monotonously decreasing internal diameters (19) of the die portions (7, 8, 9) as measured between co-operating pressing surfaces (18).

摘要： A molding is produced with a disk-shaped or plate-shaped basic body having a large number of knob-like and/or web-like elevations which merge into the basic body with inclined side surfaces. The molding is produced by pressing and sintering powdery raw materials close to the final shape. First, the boundary surfaces of the basic body are pressed to final shape as far as the transition regions of the elevations and the elevations are pressed to an oversize. The projection height of the elevations from the basic body is greater than the projection height in the finally pressed state. Their side surfaces form an angle of inclination in the range from 90°-150° with the respectively adjacent boundary surface of the basic body. Then the elevations are pressed to near final shape while the angle of inclination is enlarged to a greater value.

摘要： A technique for net shaping gear teeth of a high performance power transmission gear from a powder metal workpiece includes heating a powder metal workpiece in the form of a near net shaped gear blank having gear teeth surfaces above its critical temperature to obtain an austenitic structure throughout its surfaces, isothermally quenching the workpiece at a rate greater than the critical cooling rate of its surfaces to a uniform metastable austenitic temperature just above the martensitic transformation temperature, rolling the gear teeth surfaces of the workpiece to a desired outer peripheral profiled shape between opposed dies, each die having an outer peripheral profiled surface, while holding the workpiece at the uniform metastable austenitic temperature, the gear teeth surfaces undergoing densification, plastic deformation, and strengthening as a result of the rolling operation, and cooling the workpiece through the martensitic range to thereby harden the surfaces of the gear teeth.
