METHOD OF MANUFACTURING INTEGRALLY FORGED BIKE SUSPENSION FORK

Abstract: a method of manufacturing integrally forged bike suspension forks is provided. first initially forming a crown prototype by forging of an aluminum ingot. the crown prototype includes two lateral shoulders and a solid protuberant base. by deep drawing, the solid protuberant base and the lateral shoulders are respectively drawn and extended to form a front fork section and suspension tube sections. by milling, a top surface of each of the lateral shoulders is milled to communicate with the suspension tube section. thereby an integrally-forged suspension fork is obtained. therefore, the aluminum ingot is processed to obtain the integrally formed suspension front fork with the suspension tube sections and the front fork section. the suspension front fork is having high strength and shock resistance under impact of an external force applied to a front wheel of the bike.
