Abstract

L'invention concerne la réalisation de matrices d'emboutissage. Elle se rapporte à une matrice utilisée pour l'emboutissage d'éléments d'échangeur de chaleur, cette matrice comprenant des saillies 118 et 119 en forme de tronc conoïde et des cavités 120 tangentes aux saillies. La surface obtenue assure une très bonne répartition des contraintes dans les feuilles embouties. Application à la réalisation d'échangeurs de chaleur.
