JOINING METHOD OF METALLIC MEMBER

摘要

PURPOSE:To enable tight and integral joining of a bar-shaped member and a cylindrical member by depositing preliminarily a flux and brazing material on the contact surface formed at one end of the bar-shaped member and the end face of the cylindrical member and deforming plastically the joint part then heating the members to a prescribed temp. CONSTITUTION:A bar-shaped metallic part 1 having a bottom end part 1a and a belt-like part 1b is disposed to the cavity formed of dies 3, 5 and the bottom surface of the 2nd metallic member 2 having a round hole is pressed atop the part 1b. A flux and sheet-like brazing material are deposited on the opposed surfaces in the joint part of the members 1, 2 after a cleaning treatment. A pressurizing punch 4 inserted onto the member 1 and contacting slidingly with the die 5 is then actuated to deform plastically the joint part of the members 1, 2 by the pressurizing end 4a thus applying plastic flow to the joint part. Such forged member is heated to the m.p. of the flux and brazing material or above to complete joining. The tight joining of the metallic member with high productivity and low cost is thus made possible.
