Method to obtain in the cold state single finished sections from cold single multi-section elements, and relative machine

摘要

Method to obtain in the cold state single finished sections (11) from substantially cold single multi-section elements (12) produced by hot rolling, extrusion or drawing, the single multi-section element (12) consisting of at least two finished sections (11) (angle irons, angle irons with unequal sides, Z-sections, T-sections, flats, etc.) positioned side by side and connected together lengthwise along the terminal part of an edge, the sections (11) being separated by a web (21), the cold single multi-section element (12) being positioned and undergoing the splitting of the web (21) from the sections (11), the edges of the finished sections (11) facing the web (21) after splitting being subjected to a re-gauging operation, the finished sections (11) being then straightened and made linear at the same time. Machine to obtain in the cold state single finished sections (11) from single multi-section elements (12) produced by hot rolling or extrusion/drawing, the single multi-section element (12) consisting of at least two finished sections (11) (angle irons, angle irons with unequal sides, Z-sections, T-sections, flats, etc.) positioned side by side and connected together lengthwise along the terminal part of an edge by a web (21), the machine comprising in sequence at least one drawing assembly (36), at least one splitting assembly (20) and at least one re-gauging assembly (29).
