Method for connecting pieces accessible only from one side and assembly of such pieces

摘要

The procedure for the connecting of components (1,2) with one-sided access by using a blind rivet includes forming a truncated cone-form section (12) on the head (8) of the rivet mandrel (7) guided in the blind rivet sleeve (4), whereby the end face of this section by rotation of the blind rivet is pressed by an axially directed thrust force against the facing component. The component material in the working region is heated and made flowable, the mandrel head forms a hole penetrating the two components, and the displaced material is joined to the mandrel head like a cap. The blind rivet penetrates the two components until the set head (5) of the rivet sleeve stops against the facing component, and the rivet mandrel through upsetting of the blind side end of the rivet sleeve is withdrawn until the mandrel head remains sealed in the fixed connecting position of the two components. An independent claim is included for a device for the connecting of components with one-sided access .
