Title (EN) PRESS TOOLING
(FR) OUTILLAGE DE PRESSE
Abstract:
(EN) During the compression of a part (12), it is necessary to avoid stress concentrations upon stripping by lowering an insert (17) in order to release the top of a thin and flexible inner tube (16) so that it can expand at the location where the part will be released and so as to partially relief the inner stress of the part in the vicinity of the stripped portion.
(FR) Dans la compression d'une pièce (12), on évite les concentrations de contrainte au démoulage en abaissant un insert (17) de manière à dégager le sommet d'un tube interne (16) fin et flexible de manière qu'il puisse se dilater à l'endroit où la pièce sera démoulée et relâcher partiellement les contraintes internes dans la pièce au voisinage de la portion démoulée.
