Abstract

P rocédé et installation de fabrication par forgeage à chaud d’une pièce intermédiaire allongée Procédé de fabrication par forgeage d’une pièce intermédiaire (1) en alliage métallique allongée selon un axe longitudinal (Z), comprenant les étapes suivantes : - fabrication par forgeage à chaud d’une ébauche allongée comprenant au moins un tronçon de section transversale à faible variation ; - mise en forme de l’ébauche pour obtenir un demi-produit allongé selon un axe longitudinal comprenant une partie centrale et une première et une deuxième partie de section accrue, s’étendant de part et d’autre de la partie centrale selon la direction de l’axe longitudinal, la mise en forme de l’ébauche comprenant la réalisation de la première partie de section accrue du demi-produit par forgeage à chaud et la réalisation de la deuxième partie de section accrue du demi-produit par forgeage à chaud choisi parmi un refoulement, un repoussage, un matriçage ou un filage inverse; et - étirement à chaud du demi-produit pour obtenir la pièce intermédiaire (1). Figure pour l'abrégé : Figure 1Method and installation for manufacturing by hot forging an elongated intermediate part Method for manufacturing by forging an intermediate part (1) of metal alloy elongated along a longitudinal axis (Z), comprising the following steps: - manufacturing by forging hot forming of an elongated blank comprising at least one section of cross section with low variation; - shaping of the blank to obtain a semi-product elongated along a longitudinal axis comprising a central part and a first and a second part of increased section, extending on either side of the central part in the direction of the longitudinal axis, the shaping of the blank comprising the production of the first part of increased section of the semi-product by hot forging and the production of the second part of increased section of the semi-product by hot forging selected from upsetting, embossing, stamping or reverse spinning; and - hot stretching of the semi-product to obtain the intermediate part (1).
