Abstract

L'invention concerne les industries du formage des métaux en feuille et des lubrifiants. Pour évaluer la qualité d'un lubrifiant, on enduit un flan 9 avec le lubrifiant, on dispose le flan 9 entre une matrice 7 et un serre-flan 6, on exerce un effort de déplacement au moyen d'un poinçon 8, on fait croître l'effort de serrage du serre-flan 6 en fonction du déplacement qu'on poursuit jusqu'à ce que l'effort nécessaire au déplacement atteigne une valeur prédéterminée et on classe le lubrifiant, en relation avec le déplacement atteint, par rapport à d'autres lubrifiants évalués de façon identique. Application notamment à l'essai des lubrifiants pour emboutissage profond.
