RIVETING METHOD Russian patent published in 1997 - IPC

FIELD: rivet joint of constructions having parts made from fibrous composite materials. SUBSTANCE: method involves making stepped-diameter opening in pack of parts to be connected, with larger diameter step and transition surface between steps in part being made from metal; inserting rivet with thickened portion on rod, having length equal to height of larger diameter step, into pack opening; pressing thickened portion into larger diameter step and forming gap between metal surface of part and supporting surface of insertion rivet head; forming closing head of rivet by applying compressive force to its end; moving insertion head in axial direction relative to closing head till gap disappears. EFFECT: increased efficiency, simplified method and enhanced reliability in operation. 3 dwg
