ABSTRACT:
The invention discloses a process of forging a sprocket segment for a track-type vehicle undercarriage. The forging process produces sprocket segments that conform to very restrictive tolerances without the necessity of additional machining or finishing.
The process includes heating a metal billet (5') in an electric furnace (60), rough-shaping the billet (5'), then forging the billet (5') in a die (62) to form a sprocket segment (5) having a size and shape substantially equal to the desired finished shape of the segment (51). The forged sprocket segment (5) is trimmed and then placed in a coining die (8) wherein at least two nonparallel surfaces (A,B,C) are formed to a desired finished dimension.
The invention also includes an apparatus (8) for forging a sprocket segment to a desired finished dimension. The apparatus (8) includes an upper die member (80), a lower die member (8'), and a transversely-moveable die member (82).
