Method for manufacturing punching rivet joint for connecting thin-walled components during construction of automobile structure, involves plastically deforming metal sheet component with shaft that is expanded

摘要

The method involves punching a hollow punching rivet (16) over an upper stamp (20) by thin-walled components (10, 12) to be connected, and expanding the punching rivet in a lower stationary die (22) in a counter-position. A thin-walled, closed metal sheet component (18) formed of stainless steel or aluminum is arranged between the die and one of the neighboring thin walled components and is plastically deformed with a rotationally symmetric, cylindrical shaft (16b) that is expanded. The metal sheet component is formed as a blank whose outer diameter corresponds to triple diameter of the shaft. Independent claims are also included for the following: (1) a device for producing a punching rivet joint, comprising an automatic feeding device (2) a punching rivet joint.
