摘要： A curved extrusion includes a body that has indefinite length and a cross-section, and that is formed to contour and at least one channel cut into the cross-section that is filled with deposited material such that said cross-section of said body is restored. By cutting the channels into the cross-section of the extrusion, the extrusion may be easily formed onto a contoured tool to be curved with lower forming and residual stresses and distortion. By filling the channels with deposited material, the original cross-section and strength of the extrusion can be restored. By adding a transverse stiffener, the strength of the original extrusion may not only be restored but also further improved. By depositing material to create structural features the cross-section of the extrusion may be locally changed. The method for forming curved extrusions of the present invention may be used, for example, to produce T-chords of an aircraft.
摘要翻译：弯曲的挤压件包括具有不定长度和横截面的主体，并且其被形成为轮廓，并且至少一个通道切割成填充有沉积材料的横截面，使得所述主体的所述横截面被恢复。通过将通道切割成挤出件的横截面，挤出可以容易地形成在成型工具上，以弯曲成形和残余应力和变形。通过用沉积材料填充通道，可以恢复原始横截面和挤出强度。通过添加横向加强筋，原始挤压的强度可能不仅可以恢复，而且可以进一步改善。通过沉积材料以产生结构特征，挤出物的横截面可以局部改变。用于形成本发明的弯曲挤压件的方法可以用于例如制造飞机的T弦。
