Beschreibung
Zusammenfassung:	A method and apparatus for producing a motor vehicle component (19) from a light metal alloy includes: extruding an extruded profile (1) with, in cross section, at least two mutually different wall thicknesses (W1, W2) and at least one closed hollow chamber (2, 3, 4) and with an extrusion width (6), at least partially flattening and/or widening the cross section to a processing width (7), wherein the processing width (7) is greater than the extrusion width (6), before or after the flattening and/or widening, performing separation to form blanks (13), processing the blanks (13) by deformation to form the motor vehicle component (19). 本发明涉及种用于由轻金属合金制造机动车构件(19)的方法和设备，其中，挤出挤压型材(1)，该挤压型材在横截面上具有至少两个彼此不同的壁厚(W1、W2)和至少个封闭的空腔(2、3、4)和挤出宽度(6)；将横截面至少部分压扁和/或加宽到加工宽度(7)，该加工宽度(7)大于挤出宽度(6)；在压扁和/或加宽之前或之后分开成板坯(13)；将板坯(13)成型加工成机动车构件(19)。
