Abstract: A method for manufacturing an integrated aluminum alloy bicycle front fork is revealed. Aluminum alloy is extruded to form substrate having three rectangular bars. Cut the substrate to get a blank. The blank is set into a mold for forging the three rectangular bars into three round bars. Then burr and waste material are removed. Next the blank is set into another mold for extruding the three round bars and the three round bars are punched to have guide holes. The round bars are drilled along the guide holes and penetrated to form round tubes. A tube opening of two round tubes is flattened and narrowed. Then the two round tubes are bent downward to form fork tubes of a front fork. The rest tube forms a front fork stem. Thereby an integrated light weighted front fork with good structural strength and beautiful appearance is produced.

Abstract: A method of manufacturing a die forged crankshaft to be mounted in a two or more cylinder reciprocating apparatus includes: an upsetting step that includes upsetting a billet having a constant cross-sectional area along an entire length thereof to form a blank having an enlarged cross-sectional area at a region between a portion to be formed into a leading crank arm of the crankshaft and a portion to be formed into a trailing crank arm thereof; a die forging step that includes die forging the blank formed in the upsetting step to form a forged blank having a shape of the crankshaft with a flash; and a trimming step that includes trimming the flash from the forged blank formed in the die forging step. This makes it possible to improve the material utilization and to use a billet having a cross-sectional size as small as possible.

Abstract: An apparatus (10) for forming an article by forging. The apparatus comprises at least one die (12) having a die cavity (14) to receive material, said material (16) being at least partially molten, and at least one punch (20) adapted to slidably engage the die cavity and to exert a forming pressure on material disposed in the cavity. There is also at least one pin (24) for forming an article feature. The pin is adapted to slidably engage the die and to contact the material, the pin being further adapted to recede upon exertion of the forming pressure and to exert a feature forming pressure when receded and thereby form the article (30) having the article feature when the material solidifies under the forming pressure.
