Title (EN) PROCESS AND SYSTEM FOR PRESSURE FORMING OF A WORKPIECE
(FR) PROCÉDÉ ET SYSTÈME DE FORMAGE SOUS PRESSION D'UNE PIÈCE DE FABRICATION
Abstract:
(EN) A process (100) and a system (20, 40) for forming of a workpiece (10) using a press (20) comprising a pressure generator (21), a forming tool (22), and an at least in part elastically deformable element, are disclosed. At least one of the workpiece (10) or the forming tool (22) is heated, and the workpiece (10) is formed using the press (20) so as to obtain a formed workpiece (60). The heating of at least one of the workpiece (10) or the forming tool (22) is such that the temperature of the at least one of the workpiece (10) or the forming tool (22) during the forming of the workpiece (10) by way of forming pressure generated by the pressure generator (21) is higher than the ambient temperature.
(FR) La présente invention concerne un procédé (100) et un système (20, 40) pour former une pièce de fabrication (10) au moyen d'une presse (20) comprenant un générateur de pression (21), un outil de formage (22) et un élément au moins partiellement déformable élastiquement. Au moins l'un de la pièce de fabrication (10) ou de l'outil de formage (22) est chauffé, et la pièce de fabrication (10) est formée au moyen de la presse (20) de façon à obtenir une pièce de fabrication formée (60). Le chauffage d'au moins l'un de la pièce de fabrication (10) ou de l'outil de formage (22) est tel que la température d'au moins l'un de la pièce de fabrication (10) ou de l'outil de formage (22) pendant le formage de la pièce de fabrication (10) au moyen de la pression de formage générée par le générateur de pression (21) est supérieure à la température ambiante.
