METHOD OF HYDROFORMING ARTICLES AND THE ARTICLES FORMED THEREBY

A hydroformable frame element is formed from the combination of at least two elements (12, 14). The at least two elements are designed with a partially overlapping region, with an annular space (20) defined within the overlapping region. The annular space is filled with adhesive, which is then cured...

Beschreibung
Zusammenfassung:	A hydroformable frame element is formed from the combination of at least two elements (12, 14). The at least two elements are designed with a partially overlapping region, with an annular space (20) defined within the overlapping region. The annular space is filled with adhesive, which is then cured to bond the at least two elements together. The adhesive bond is designed to withstand the stresses caused by the hydroforming operation and to retain its strength so that the hydroformed article is then usable as a vehicular frame element (40). Selon l'invention, un élément de cadre hydroformable est formé à partir d'une combinaison d'au moins deux éléments (12, 14). Ces deux éléments au moins présentent une zone de chevauchement partiel à l'intérieur de laquelle est défini un espace annulaire (20). Cet espace annulaire est rempli au moyen d'un adhésif qui est ensuite durci pour relier entre eux lesdits deux éléments au moins. Cette liaison adhésive est conçue pour résister aux contraintes provoquées par l'opération d'hydroformage et pour conserver sa résistance, de sorte que l'article hydroformé peut ensuite être utilisé comme élément de cadre de véhicule (40).
