Abstract
In a forming apparatus, stationary journal dies (10U, 10B) and movable journal dies (11U, 11B) each hold and retain rough journal portions (J′) of a preform blank (4) therebetween, and crank pin dies (12) contacts rough crank pin portions (P′) thereof, and in this state, the movable journal dies (11U, 11B) are moved axially toward the stationary journal dies (10U, 10B) and the crank pin dies (12) are moved in the same axial direction and in an eccentric direction. Rough crank arm portions (A′) are axially compressed to reduce their thickness to that of crank arms of a forged crankshaft, and the rough crank pin portions (P′) are pressed in the eccentric direction to increase eccentricity to that of the crank pins of the forged crankshaft. Consequently, it is possible to form a blank for finish forging having a shape generally in agreement with the shape of the forged crankshaft.
