Abstract

L'invention concerne un dispositif de fabrication de demi-chaîne de fermeture à glissière qui comporte un nombre réduit de pièces et permet de réduire le coût de fabrication. Ce dispositif de fabrication de demi-chaîne de fermeture à glissière comprend : une partie de coupe (20) pour couper un matériau de fil métallique (W), c'est-à-dire une pièce d'ébauche pour éléments de fermeture à glissière (E) ; une partie de formage de tête (40) pour former des têtes de mise en prise (E1) sur des éléments de fermeture à glissière coupés ; et une partie de sertissage (60) pour fixer les éléments de fermeture à glissière, sur lesquels les têtes de mise en prise sont formées, à une bande de fermeture à glissière (T). La partie de coupe comporte : une matrice de coupe (22) équipant un premier vérin (21) et comportant un trou d'insertion de matériau de fil métallique (22a) ; et un poinçon de coupe (23), placé en face de la matrice de coupe et coupant le matériau de fil en coopération avec celle-ci. La partie de formage de tête comprend : un poinçon de formage (42) équipant un second vérin (41) et formant les têtes de mise en prise sur les éléments de fermeture à glissière ; et une matrice de formage (43) équipant le premier vérin et qui reçoit l'impact du poinçon de formage. La matrice de formage (31) est formée d'un seul tenant avec la matrice de coupe (6).
