Abstract
A method of producing ball joints of the type that include a ball and stem member pivotally mounted in a housing, the method comprising forming the ball stud or pivoted member by heading a work-piece to provide an enlarged head portion that forms a first section of the spherical bearing surface of the ball stud, and by next forming a second head portion from a second work-piece that provides a second section of the spherical bearing surface of the ball stud. The two formed work-pieces are next welded together at confronting surfaces to provide a fused junction and the junction and spherical surface is next machined to provide the finished bearing head of spherical contour.
Claims2
The method of making ball studs for pivot joints comprising, in combination, forming a shank portion by heading a work-piece to provide an enlarged head portion provided with an outwardly convex generally spherical surface and an inwardly facing junction forming surface;
- forming a second head portion from a second work-piece provided with a generally spherical outer surface, a second inwardly facing junction forming surface, and a central bore;
- assembling said first and second work-pieces by extending said shank through said bore with said junction forming surfaces in confronting relationship;
- welding said first and second head portions together at said confronting junction forming surfaces to provide a fused junction;
- and machining said junction and bearing surfaces to provide a finished bearing head of substantially spherical contour.
