Thin plate-shaped workpiece e.g. sheet metal, assembling method, involves locally connecting sheet metals by common plastic deformation in assembling region, where deformation takes place via flow hole molding of assembling components

摘要

The method involves locally connecting sheet metals (2, 3) by common plastic deformation in an assembling region. The plastic deformation takes place via a flow hole molding of assembling components. Friction heat from the sheet metals leads axial and rotational movement of a flow forming tool (1) to form a common passage. A contact fixture is formed within a passage region in a contact zone (5) of the sheet metals.
