Piercing and riveting tool, rivet, and method

摘要

A piercing and riveting tool utilizes a rivet assembly that includes a rivet body and a mandrel. In a single operation, the tool clamps one or more workpieces in place; pierces the clamped workpiece(s) with a piercing surface of the mandrel head, prevents the premature deformation of the rivet body with the mandrel head, deforms an end of the rivet body after the end of the rivet body has passed through the workpiece(s) with the mandrel head to set the rivet, separates the mandrel head from its shank, and unclamps the workpiece(s) to which the rivet body is secured.
