Zusammenfassung: | A method for moulding a sheet (L) into a component of complex shape having areas with different mechanical properties, particularly a motor-vehicle component. The method involves a first heating step of the sheet (L) carried out by means of a kiln (1), prior to forming the component. The kiln (1) comprises a main body with a roller shape (3), having a plurality of sectors (4) extending along a radial direction with respect to a longitudinal axis (X) of the roller body (3). The sectors (4) are configured to each receive a sheet (L), so that the main body with a roller shape (3) is arranged to simultaneously carry a plurality of sheets (L). The kiln (1) further comprises a plurality of heating elements (5) incorporated in said roller-shaped main body (3), so as to heat the sheets (L) in contact with the roller body (3). The kiln (1) further comprises at least one electronically-controlled drive motor, arranged to rotate the roller-shaped main body (3) around the longitudinal axis (X) of the kiln (1), so as to vary the position of the sectors (4) with respect to the inlet and outlet ports (6, 7). The method also includes an additional heating step following extraction of the sheets (L) from the kiln (1), wherein the sheets (L) are locally heated only at one area, so as to obtain sheets (L) with areas heated to different temperatures. |
