Title (EN) METHOD AND DEVICE FOR FASTENING AT LEAST TWO WORKPIECES
(FR) PROCÉDÉ ET DISPOSITIF DE FIXATION D'AU MOINS DEUX PIÈCES
Abstract:
(EN) The invention concerns a method for fastening at least two workpieces (1,2) together by a punch rivet (3) wherein at least one workpiece (1) is a metallic workpiece (1) and wherein the at least one metallic workpiece (1) is heated to an elevated temperature for setting the punch rivet (3). Further, the invention concerns a device (10) for fastening at least two workpieces (1,2) together by a punch rivet (3)wherein at least one workpiece (1) is a metallic workpiece (1),comprising a die (5), a riveting punch (6), the riveting punch (6) being moveable toward the die (5), a blank holder (7) for holding the workpieces (1,2) during movement of the riveting punch (6) toward the die (5) for setting the punch rivet (3) to fasten the workpieces (1,2), wherein a heating element (8) is provided for heating at least one of the workpieces (1,2).
(FR) L'invention concerne un procédé de fixation l'une à l'autre d'au moins deux pièces (1,2) par un rivet poinçonneur (3), au moins une pièce (1) étant une pièce métallique (1) et ladite pièce métallique (1) étant chauffée à une température élevée pour permettre la mise en place du rivet poinçonneur (3). En outre, l'invention porte sur un dispositif (10) destiné à fixer l'une à l'autre au moins deux pièces (1,2) par un rivet poinçonneur (3), au moins une pièce (1) étant une pièce métallique (1), comprenant une matrice (5), un poinçon de rivetage (6), le poinçon de rivetage (6) étant mobile vers la matrice (5), un support d'ébauche (7) pour maintenir les pièces (1,2) lors du déplacement du poinçon de rivetage (6) vers la matrice (5) pour mettre en place le rivet poinçonneur (3) pour fixer les pièces (1,2), un élément chauffant (8) étant fourni pour chauffer au moins une des pièces (1,2).
