Abstract

La présente invention porte sur un procédé de calibrage d'une pièce cylindrique (1) après mise en forme par déformation plastique d'un matériau métallique présentant un retrait structural maximum à une température de retrait maximum comprise entre une première température et une deuxième température inférieure à la première, caractérisé par le fait qu'il comprend les étapes successives suivantes :
- mise en place de la pièce (1) dans un four vertical,
- positionnement d'un outillage de calibrage interne de diamètre supérieur à celui de la pièce lors de son retrait structural maximum, au droit de la pièce en dehors du four,
- chauffage de la pièce (1) jusqu'à une première température,
- descent et mise en place, à l'intérieur de la pièce, d'un outil de calibrage (8) interne de diamètre supérieur à celui du retrait structural maximum de la pièce,
- transport de l'ensemble formé par la pièce et l'outil de calibrage jusqu'à une cuve de trempe
- refroidissement de la pièce jusqu'à une température inférieure à ladite deuxième température,
- extraction de l'outil de calibrage interne (8).The present invention relates to a method for calibrating a cylindrical part (1) after shaping by plastic deformation of a metallic material having a maximum structural shrinkage at a maximum shrinkage temperature between a first temperature and a second lower temperature at the first, characterized by the fact that it comprises the following successive steps:
- setting up the part (1) in a vertical oven,
positioning of an internal calibration tool of diameter greater than that of the part during its maximum structural shrinkage, to the right of the part outside the furnace,
- heating the room (1) to a first temperature,
- Descent and establishment, inside the room, an internal calibration tool (8) greater in diameter than the maximum structural shrinkage of the room,
transport of the assembly formed by the workpiece and the calibration tool to a quenching tank
- cooling of the room to a temperature below said second temperature,
- extraction of the internal calibration tool (8).

Le procédé s'applique à la fabrication de carters de turbomachine.
