EQUIPMENT FOR PRODUCING A CLOSED-SECTION CROSS-MEMBER, COMPRISING AN ADAPTABLE-LENGTH PUNCH AND/OR MATRIX, AND CORRESPONDING PRODUCTION METHOD

摘要

A piece of equipment for production of a closed-section cross-member configured to connect two longitudinal arms of a flexible axle of a motor vehicle. The equipment includes at least one matrix configured to cooperate with a punch to form a torsion area of a certain length on the closed section of the cross-member and a mechanism to maintain the cross-member in position. The length of the matrix and/or the punch can be adapted to adapt the length of the torsion area.
