Abstract

L'invention concerne un procédé et une presse pour percer un bloc métallique chaud. Un bloc 1 comporte un premier poinçonnage en forme de calotte, produit hors d'un support 5, ayant élargi le bloc dans la zone 3 supérieure pour y créer une zône de centrage dans le support. Une deuxième zone de centrage 6 est créée par rétrécissement de l'ouverture inférieure du support portant sur une plaque de cisaillement. Un lubrifiant 4 est disposé dans le poinçonnage en forme de calotte. Le poinçon de perçage 8 est tronconique et le bloc est libre de s'élargir dans le support sous l'effet de la pression appliquée sur le poinçon de perçage L'invention s'applique au perçage des blocs métalliques.
