Title
(EN) EQUIPMENT FOR PRODUCING A CLOSED-SECTION CROSS-MEMBER, COMPRISING AN ADAPTABLE-LENGTH PUNCH AND/OR MATRIX, AND CORRESPONDING PRODUCTION METHOD
(FR) OUTILLAGE DE FABRICATION D'UNE TRAVERSE A SECTION FERMEE COMPRENANT UNE MATRICE ET/OU UN POINCON DE LONGUEUR ADAPTABLE, ET PROCEDE DE FABRICATION CORRESPONDANT
Abstract
(EN)
The invention relates to a piece of equipment for the production of a closed-section cross-member which is intended to connect two longitudinal arms of a flexible axle of a motor vehicle. The inventive equipment comprises at least one matrix (3) which is intended to co-operate with a punch (2) in order to form a torsion area (L) of a certain length on the closed section of the cross-member and means for maintaining the cross-member in position. The invention is characterised in that the length of the matrix (3) and/or the punch (2) can be adapted in order to adapt the length of the torsion area (L).
(FR)
L'invention a pour objet un outillage de fabrication d'une traverse à section fermée destinée à relier deux bras longitudinaux d'un essieu souple de véhicule automobile, ledit outillage comprenant au moins une matrice (3) destinée à coopérer avec un poinçon (2) pour former sur ladite section fermée de ladite traverse une longueur de zone de torsion (L), et des moyens de maintien en position de ladite traverse, caractérisé en ce que ladite matrice (3) et/ou ledit poinçon (2) sont adaptables en longueur en vue d'adapter ladite longueur de ladite zone de torsion (L).
