54 Method of making a flanged tubular metallic part US10419154 2003-04-21 US07013696B2 2006-03-21 Minoru Ando; Shigahisa Saida
A method of making a flanged tubular metallic part by cold forging is provided. The method comprises a step of forming an axial depression in a blank and a flange forming step of making the depression axially deeper while causing a metal of the blank to flow radially outward thereby forming the blank into an intermediate product having a flange. The flange forming step includes axially moving an inner punch of a die assembly so as to cause a leading end of the inner punch to be positioned more forward than a backward side surface of the flange thereby causing the intermediate product to be formed with a sleeve portion that is position backward of the flange while allowing an outer punch of the die assembly to apply a biasing force to a backward side surface of the flange during formation of the flange.
55 Fabrication method of metal shell of spark plug US10188314 2002-07-03 US06792786B2 2004-09-21 Kazuhiko Tanaka
A fabrication method of a metal shell to be installed on a park plug is provided which is made up of a small-diameter portion, a large-diameter portion, and a wrapping portion. The wrapping portion is to be wrapped by staking about the spark plug to achieve installation of the metal shell on the spark plug. The method comprises pressing a workpiece with a punch to shape the wrapping portion of the metal shell in a first cold forging process and processing the workpiece to shape the small-diameter portion of the metal shell in a second cold forging process different from the first cold forging process. This produces the metal shell which is less susceptible to cracks when installed on the spark plug and has an increased service life.
