Abstract

Viene illustrato uno stampo ad utensile perfezionato a geometria variabile che impiega segmenti di stampo (12) per l'uso nella curvatura di materiali con stampi nella pressa. Uno stampo formatore (10) è costruito di una pluralità di porzioni a segmenti (12) che sono radialmente regolabili per curvature di raggi differenti. Inserti intercambiabili (20) negli stampi a segmenti (12) consentono la curvatura di materiali con vari diametri e varie sagome esterne.
