Title
(EN) SPLIT DIE FOR FORMING GROOVED WORKPIECES
(FR) MATRICE SEGMENTEE POUR FORMATION DE PIECES A USINER RAINUREES
Abstract
(EN)
A method of forming a radially expandable externally grooved tubular fastener from metal, comprising the steps of providing a suitable tubular blank (11) having a tubular wall (12) and squeezing the tubular wall between an internal member (17) with a surface which engages the internal tubular wall face (15) of the blank and a plurality of external members (18) provided with suitably shaped surfaces engaging the external tubular wall face (16) of the blank (11) thereby to form grooves (23) on the external tubular wall face (15) of the blank (11).
(FR)
L'invention concerne un procédé de formation d'un élément d'attache tubulaire rainuré à l'extérieur, extensible radialement, à partir de métal. Ce procédé comprend les étapes consistant: à prendre un flan (11) tubulaire approprié comprenant une paroi (12) tubulaire; et à compresser la paroi tubulaire entre un élément (17) intérieur comprenant une surface qui vient en contact avec la face (15) de paroi tubulaire intérieure du flan et une pluralité d'éléments extérieurs (18) pourvus de surfaces dimensionnées de manière appropriée en contact avec la face (16) de paroi tubulaire extérieure du flan (11), afin que soient formées des rainures (23) sur la face (15) de paroi tubulaire intérieure du flan (11).
