TIGE BRISABLE POUR DISPOSITIF DE FIXATION, ET SON PROCEDE D'OBTENTION
L'invention est relative à un dispositif de fixation comprenant une tige 10 dont le corps 14 présente de multiples gorges 22 et un manchon déformable 12 dont la matière, sous l'action d'un outil 44 pénètre dans les gorges avant que la tige soit rompue par traction. Pour obtenir des ca...

| description | L'invention est relative à un dispositif de fixation comprenant une tige 10 dont le corps 14 présente de multiples gorges 22 et un manchon déformable 12 dont la matière, sous l'action d'un outil 44 pénètre dans les gorges avant que la tige soit rompue par traction. Pour obtenir des caractéristiques régulières et convenables, la tige est en acier qui, par traitements thermiques successifs a été amenée à une structure austénitique à gros grain, puis martensitique puis sorbitique, à grain fin et homogène. (CF DESSIN DANS BOPI)
A headed steel pin for a multi-grip fastener of the pin and swageable collar type has a homogeneous microstructure, and consists substantially entirely of sorbitic tempered martensite. Suitable coarse-grained medium carbon steel is shaped to form a headed pin having a plurality of identical, regularly spaced, annular, combination grooves each able to function alternatively as a locking groove, a pulling groove, or a breaker groove. The shaped pin is heat treated, the steel rendered homogeneously martensitic and then tempered at a temperature approaching as closely as practicable to the lower critical temperature of the steel, to convert the martensitic steel entirely to sorbite. The finished pin has a suitable balance of brittleness, toughness, ductility and impact strength, and tends to break cleanly and reliably at a selected one of the combination grooves when the fastener is installed in a workpiece. |
