US 2017/0320127 A1 · INTERCHANGEABLE DIE, JOINING TOOL AND JOINING METHOD

Abstract

An interchangeable die comprises a die head, on which a die feature is formed, and a die shank extending in an axial direction from the die head. The die shank includes a first axial shank section, which is adjacent to the die head, and a second axial shank section, which is arranged on the opposite axial side of the first axial shank section from the die head. The first axial shank section has a first diameter and the second axial shank section has a second diameter smaller than the first diameter. The die shank is introducible into a shank receptacle of a die receiving section of a joining tool. A fastening contour for fastening the interchangeable die to the joining tool is formed on the interchangeable die. The fastening contour is configured such that a plug-and-turn connection is establishable between the interchangeable die and the joining tool.
