Title (EN) TOOL SET HAVING DEFLECTION COMPENSATION
(FR) ENSEMBLE D'OUTILS À COMPENSATION DE DÉVIATION
Abstract:
(EN) A tool and die set and related method of use of the tool and die set in a press for the compaction of a powder metal into a preform involves an uneven amount of positional deflection of at least two lower or upper tool members. This asymmetrical elastic response under load may help to eliminate cracking of the part after the compressive load is removed.
(FR) L’invention concerne un ensemble outil et matrice et un procédé d'utilisation associé de l'ensemble outil et matrice dans une presse pour le compactage d'un métal en poudre en une préforme impliquant une quantité irrégulière d’écart de position d'au moins deux éléments d'outil inférieurs ou supérieurs. Cette réponse élastique asymétrique sous charge peut aider à éliminer la fissuration de la partie après que la charge de compression a été retirée.
