Abstract
This method for producing a die forged crankshaft to be mounted in a reciprocating engine of two or more cylinders includes: an upsetting step in which a billet having a uniform cross sectional area along its entire length is upset thereby molding a buster having an expanded cross sectional area in a section extending from the location corresponding to the crank arm portion at the head of the crankshaft to a location corresponding to the crank arm portion at the tail of the crankshaft; a die forging step in which the buster molded in the upsetting step is die forged to mold a forged material shaped into the form of a crankshaft and having flash attached; and a flash removing step for removing flash from the forged material molded in the die forging step. Thus yield is improved and the cross sectional size of the billets used can incorporate smaller sizes.
