Abstract

A swaging machine for swaging a workpiece as it is axially fed or for recessing a workpiece when it is axially fixed and which comprises two or more dies and two or more stems for actuating said dies, die guiding means for guiding said dies, a front cover for covering said dies, and wedges extending between said stems and dies to vary the radial spacing of said dies and stems. The machine is provided with a die changing mechanism comprising a pivotally movable or displaceable die handling member, which is formed with juxtaposed chamber, which contain respective gripping means for gripping respective sets of dies, and said die handling member is pivotally movable or displaceable to a plurality of positions in which respective ones of said chambers are centered on a predetermined workpiece feeding axis. Said die handling member comprises a cam slot, which is engaged by the front cover and the front cover is pivotally movable or displaceable, like the die handling member, and is thus movable between an operating position, in which said front cover covers said dies, and a die changing position, in which said dies are exposed.
