发明名称 Method of manufacturing a crown-shaped component
摘要 <p>Described is a method of manufacturing a crown-shaped component 3 having a plurality of axially extending protrusions 2 which are formed at an end of a cylindrical portion 1. The method comprises the steps of: upsetting the cylindrical portion into a cylindrical blank 10a having protrusions arrayed on and along the inner circumferential surface of a remaining part 12; annealing the cylindrical blank; removing the remaining part by cutting; and subjecting the resultant blank to a shot blasting process, whereby a magnetic characteristic of the resultant crown-shaped component is improved. <IMAGE></p>
