Abstract

The invention refers to a die for obtaining a part including walls turned at the end in a small edge, characterised by the fact of including a screw tap supported by a lower base fixed to the surface of a press suitable for making contact with the base and walls of the part, equipped on the perimeter with an annular support component for the edge suitable for coming into contact with flexible supports fixed to the said base, at the edge of which there is a ring used for coming into contact with the scrap and by including also, connected to an upper base integral to the ram of the press, a plate suitable for coming into contact with the base of the part, an annular component integral to the base suitable for coming into contact with the edge, a ring supported by the said base with flexible components inserted, which maintain the said ring protruding downwards in relation to the adjacent annular component by an extent approximately equal to half of the thickness of the sheet metal being worked.
