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).
Claims27
Manufacturing method for metal sections (P;
- P1;
- P2;
- P3) in which the cross section is composed of at least two individual, non-aligned parts, said method is characterised in that it is applied to the manufacturing of complex shaped sections exclusively composed of non-plane parts that forma an angle that can be of any degree and evolutionary according to the length of the section, and in that the method also consists of cutting out the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) in at least one metal plate, according to the measurements that correspond to each one of the said parts, and the assembly of these elements together to form said metal section.
Method as described in any of the previous claims in which the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) are assembled by welding.
Method as described in all claims between 6 and 11, in which the welding operation is effectuated without the addition of other material.
Method as described in all claims between 6 and 11, in which the welding operation is effectuated in various points along the contact line between the two elements.
Method as described in all claims between 6 and 11, in which the welding operation is effectuated in continuous mode along the contact line between the two elements.
Method as described in any of the previous claims in which the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) are maintained in contact with each other using clamping equipment, in a position established at the moment of assembly.
Method as described in any of the previous claims in which a three dimensional drawing is made of the metal section (P;
- P1;
- P2;
- P3) to its final measurements, followed by a drawing of the flat outline of each of the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) before these are cut out.
Method as described in any one of the previous claims in which several identical elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) can be cut out simultaneously from a stack of plates.
Method as described in any of the previous claims in which at least some of the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) are hollowed out.
Method as described in any of the previous claims in which several of the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) are cut from the same metal plate arranging the layout position to minimise metal waste.
Method as described in any of the previous claims in which several of the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) using a cutting technique chosen from the group, including cutting out using high speed laser beam, abrasive water jet, and traditional mechanical machining.
Method as described in any of the previous claims in which at least one of the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) is subjected to a complementary surface treatment before element assembly.
Method as described in any of the previous claims in which the elements (A, B;
- A1, B1;
- A2, B2;
- A3, B3) are assembled, and where at least one of the elements has a variable thickness.
Method as described in any of the previous claims in which (A, B;
- A1, B1;
- A2, B2;
- A3, B3) are assembled, and where at least one of the elements has a variable width.
Method as described in any of the claims between 1 and 22 in which (A, B;
- A1, B1;
- A2, B2;
- A3, B3) are assembled, and where the elements have constant width and thickness.
