Embodiment Construction

[0054] As noted above, embodiments of the present invention generally relate to systems and methods for fabricating forged powder metal components with transverse features using core material. As used herein, "lateral feature" includes, but is not limited to, a depression in a forged powder metal part of any one or more of shape, size, and gauge. These depressions, and thus lateral features, may include, but are not limited to, holes, grooves, channels, notches, dimples, threads, cavities, undercuts, crosscuts, and indentations. Additionally, as used herein, "powder metal" may include, but is not limited to, aluminum, titanium, iron, steel, brass, stainless steel, bronze, any alloys thereof, and any combination thereof.

[0055] First refer to figure 1 , one embodiment of the present invention relates to a system 10 for fabricating a forged powder metal part 28 having transverse features. The system 10 includes powder metal 12 , core material 14 , powder metal mold 16 , sint...

Abstract

Systems and methods produce forged powder metal parts respectively comprising a transverse feature. A system may comprise a powder metal die, a sintering oven, a forging apparatus, a core material, and a powder metal. The powder metal die may receive and compact the core material and the powder metal to form a compacted powder metal part with at least a portion of the core material embedded therein to define a transverse feature in the compacted powder metal part. The sintering oven may receive and sinter the compacted powder metal part with the core material remaining embedded therein to maintain the definition of the transverse feature during sintering. The forging apparatus may receive and forge the sintered powder metal part with the core material remaining embedded therein to maintain the definition of the transverse feature during forging with the embedded core material being removable from the forged powder metal thereafter.

Description

technical field [0001] The present invention generally relates to powder metal parts having lateral features. More specifically, the present invention relates to systems and methods for fabricating forged powder metal parts having transverse features. Background technique [0002] Conventional systems and methods of making powder metal parts with lateral features in the prior art utilize a core material to define the lateral features during the compaction and sintering stages of the powder metal part manufacturing process. However, the core material utilized is substantially formed of a substance having a melting point lower than that of the powder metal reached during the sintering stage. Thus, the core material melts, evaporates and / or infiltrates the powder metal part during the sintering stage. Such substances forming the core material generally include copper and / or zinc. As the core material melts, evaporates, and / or infiltrates the powder metal part, lateral featur...
