Abstract
(EN)
A method for manufacturing a cylinder tube, including a joining step in which an end surface (15) of a tube main body (10) and a flange portion (25) are abutted against each other and joined by friction pressure welding while in a state in which a through-hole (11) of the tube main body (10) and a protruding part (21) of a head member (20) are fitted to each other across a prescribed fitting clearance (FC) therebetween. The tube main body (10) has an inclined inner circumferential surface (13) the inner diameter of which decreases with distance from the end surface (15) along a rotation axis (O). In the joining step a fluid material plastically flowing from the end surface (15) of a first member and the flange portion (25) of a second member fills the fitting clearance (FC) from the base side of the protruding part (21) until the distal end of the fluid material is positioned inside the range of the inclined inner circumferential surface (13) in the rotation axis (O) direction. By means of the fluid material a noncontact portion (26b) and the first member are joined, and the inclined inner circumferential surface (13) and an outer peripheral surface of the protruding part (21) are joined.

L’invention concerne un procédé de fabrication d'un tube cylindrique qui comprend une étape d'assemblage dans laquelle une surface terminale (15) d'un corps principal de tube (10) et une partie bride (25) sont mises en butée l'une contre l'autre et assemblées par soudage par frottement avec pression tout en étant dans un état dans lequel un trou traversant (11) du corps principal de tube (10) et une partie saillante (21) d'un élément tête (20) sont emboîtés l’un dans l’autre dans un espace de montage (FC) prescrit entre eux. Le corps principal de tube (10) présente une surface circonférentielle interne inclinée (13) dont le diamètre interne diminue progressivement depuis la surface terminale (15) le long d'un axe de rotation (O). Dans l'étape d’assemblage, un matériau fluide, s'écoulant plastiquement depuis la surface terminale (15) d'un premier élément et la partie bride (25) d'un second élément, remplit l’espace de montage (FC) depuis le côté base de la partie saillante (21) jusqu'à ce que l'extrémité distale du matériau fluide soit positionnée dans la portée de la surface circonférentielle interne inclinée (13) dans la direction de l'axe de rotation (O). Au moyen du matériau fluide, une partie sans contact (26b) et le premier élément sont assemblés, et la surface circonférentielle interne inclinée (13) et une surface périphérique externe de la partie saillante (21) sont assemblées.
