Abstract

Emboutissage en continu de trous dans un matériau tubulaire. Le procédé selon l'invention consiste à emboutir dans un tube des trous situés face à face au moyen d'outils se déplaçant dans des sens antagonistes de l'extérieur vers l'intérieur du tube, les déchets d'emboutissage étant évacués de la matrice qui se trouve à l'intérieur du tube. Utilisable pour former en continu des trous situés face à face sur la paroi d'un tube de section quelconque.Continuous stamping of holes in tubular material. The method according to the invention consists in stamping in a tube holes located face to face by means of tools moving in opposing directions from the outside to the inside of the tube, the stamping waste being discharged from the die. which is inside the tube. Can be used to continuously form holes located face to face on the wall of a tube of any section.
