Abstract

Un outil de poinçonnage pour fixer des platelages en acier adjacents le long dun joint à chevauchement latéral positionne une première et une deuxième mâchoire dun côté du joint, et positionne une troisième, une quatrième et une cinquième mâchoire de lautre côté. Un actionneur comprime les deux jeux de mâchoires; des lames aux extrémités de telles mâchoires cisaillent le joint pour créer deux fentes qui sétendent dans une direction séparée par une troisième fente qui sétend dans lautre direction. La première lame de mâchoire passe entre la troisième et la quatrième lame de mâchoire, et la deuxième lame de mâchoire passe entre la quatrième et la cinquième lame de mâchoire. Les lames sont fuselées pour éviter un blocage au moment de la libération. Les lames peuvent comprendre des parties de poinçonnage semi-cylindriques et peuvent se présenter sous forme de lames rapportées amovibles couplées aux mâchoires, comme au moyen dassemblages à queue daronde. Les mâchoires peuvent être faites dun métal avec une dureté inférieure à celle des lames rapportées amovibles.
