This experimental thesis is primarily based on the modification and adaptation of a die for reverse extrusion, used for extruding a billet with different characteristics from ours. The process involves the plastic deformation of an aluminum alloy billet positioned within a die, using a punch, to obtain a cylindrical component. The reverse extrusion was repeated with three punches of different diameters, creating components with different thicknesses and heights. Specifically, the following components were modified, modeled with a software and drafted: the die, die holder, extractor, punches, centering rings, and end stops
Questa tesi sperimentale si basa principalmente sulla modifica e adattamento di uno stampo per estrusione inversa, utilizzato per l’estrusione di una billetta con caratteristiche diverse dalla nostra. Il processo prevede la deformazione plastica, tramite un punzone, di una billetta in lega di alluminio posizionata all’interno di una matrice, al fine di ottenere un componente cilindrico. L’estrusione inversa è stata ripetuta con tre punzoni di diametro diverso, creando componenti aventi spessore ed altezza differenti. In particolare, sono stati modificati, quindi modellati con un software e messi in tavola: matrice, porta-matrice, estrattore, punzoni, anelli di centraggio e fermacorsa.

The process involves the plastic deformation of an aluminum alloy billet positioned within a die, using a punch, to obtain a cylindrical component. The reverse extrusion was repeated with three punches of different diameters, creating components with different thicknesses and heights.
