blindniet for components of different wall thickness and process for the manufacture of such a blindniets

摘要

The blind rivet assembly has a sleeve with a swage head and a sleeve shaft. A mandrel having a head and a shaft is guided through the sleeve. The mandrel shaft is rigid and the sleeve shaft is provided with a deformation region that extends in the longitudinal direction of the sleeve. The deformation region is designed such that a closing head is formed at different longitudinal positions of the deformation area by sleeve folding. The deformation region has continuously decreasing mechanical strength properties in the direction towards the swage head. The blind rivet enables to easily join structural parts of different thicknesses and guarantees at the same time to tear off the mandrel shaft with the swage head in a planar manner.
