Abstract
To create a metal section (P3) of complex shape, a three-dimensional drawing is made of the final size, then plane drawings are developed and made of each of the elements that form a distinct part of the section. These elements are then cut out (A3, B3) in at least one metal plate. Cutting operations are preferably executed flat in the flat plate. If necessary, at least one of the elements (A3, B3) is then formed. Lastly, the elements (A3, B3) are assembled together by welding for example, to form the section (P3).
Claims18
Manufacturing method for a metal profile having a T-shaped cross-section in a direction substantially orthogonal to a length direction of the profile, said metal profile including a first non-plane metal part forming a lower wing of the T-shaped cross section and a second non-plane metal part forming an upper wing of the T-shaped cross-section, said first and second non-plane metal parts being non-aligned and forming, one relative to the other, an angle evolutionary according to the length direction of said metal profile, wherein said method comprises the steps of:
- defining a substantially flat outline of the first non-plane metal part and a substantially flat outline of the second non-plane metal part;
- cutting out in at least one flat metal plate a first flat metal element following the flat outline of the first non-plane metal part and a second flat metal element following the flat outline of the second non-plane metal part, a longitudinal edge of the first metal element being beveled according to said evolutionary angle;
- forming the first flat metal element according to the non-plane shape of the first non-plane metal part and the second flat metal element according to the non-plan shape of the second non-plane metal part;
- and
- coupling the longitudinal edge of said first metal element to a face of said second metal element to thereby form said metal profile having a substantially T-shaped cross section.
