Abstract
A blind rivet setting method enables a modified step approach to grip and pull multiple diameters of blind rivet mandrels to fracture, easily feed the remaining spent mandrel portion through a blind rivet tool, and collect and more efficiently dispose of substantially shortened spent mandrel portions when a blind rivet mandrel collection system is utilized.
Claims8
A method of setting a rivet, comprising;
- providing a rivet comprising:
- a hollow body having a first end, a second end, and a tube shank extending between the first end and the second end;
- a head flange configured at the second end of the hollow body;
- and
- a mandrel passing through the hollow body and having a first end and a second end, the first end of the mandrel coupled with the first end of the hollow body, and the second end of the mandrel extending beyond the head flange a distance of a minimum of 0.25 inches to a maximum of 0.75 inches
- wherein the mandrel has a smooth surface for the gripping teeth of the jaws of a riveting tool to capture during rivet setting;
- inserting the rivet into the riveting tool and inserting the rivet into a workpiece to be riveted;
- activating the riveting tool to grip a portion of the second end of the mandrel and pull the mandrel of the rivet until the hollow body is substantially deformed to set the first end of the mandrel;
- releasing the mandrel and re-setting the mandrel within the riveting tool, such that the riveting tool grips a portion greater than the portion of the second end griped prior to re-setting the mandrel;
- and
- pulling the mandrel until the mandrel fractures.

- a hollow body having a first end, a second end, and a tube shank extending between the first end and the second end;
- a head flange configured at the second end of the hollow body;
- and
- a mandrel passing through the hollow body and having a first end and a second end, the first end of the mandrel coupled with the first end of the hollow body, and the second end of the mandrel extending beyond the head flange a distance of a minimum of 0.25 inches to a maximum of 0.75 inches
- wherein the mandrel has a smooth surface for the gripping teeth of the jaws of a riveting tool to capture during rivet setting;
- inserting the rivet into the riveting tool and inserting the rivet into a workpiece to be riveted;
- activating the riveting tool to grip the second end of the mandrel with a portion of the gripping teeth surface of the split jaws that is less than the complete gripping teeth surface of the split jaws available;
- implementing a first pull by pulling the mandrel of the rivet, thus deforming the hollow body;
- at a state at which the hollow body is deformed sufficiently enough to enable the mandrel to travel further into the riveting tool, releasing the mandrel and re-setting the mandrel within the riveting tool, such that the riveting tool grips the mandrel with a portion of the jaw gripping surface that is greater than the portion of jaw gripping surface used for the first pull;
- and
- implementing at least a second pull by pulling the mandrel to set the rivet.
