Low voltage electromagnetic process and apparatus for controlled riveting

摘要

The present invention relates to a method and apparatus for minimizing undesirable gaps in riveted assemblies. The method includes the steps of selecting a rivet (22) having a head (21) and a tail (23) with identical forming characteristics, positioning the selected rivet in an assembly that is countersunk (25) on one of two sides, and applying a force over time to the head (21) of the rivet (22) and a force over time to the tail (23) of the rivet (22) that are equal and opposite, compensating for force unbalancing characteristics of the countersink (25).
