Embodiment Construction

[0037]The same reference numbers are used in the figures for identical or similar components, even if their description is not repeated for reasons of simplification.

[0038] figure 1 The profile 1 produced according to the invention is shown in cross section. It can be clearly seen that the profile 1 has an uneven cross-sectional profile which is in particular undulating and W-shaped. Furthermore, it can be seen that the profile 1 has two different wall thicknesses w1 and w2 in cross section, wherein w2 is here greater than w1. Furthermore, the wall thickness w1 is constant here and the wall thickness w2 is constant in the corresponding area over the cross-sectional distribution. However, it is conceivable within the scope of the invention that the wall thicknesses w1 , w2 also be varied, for example increased or decreased, since there is a degree of freedom of shaping with respect to the wall thicknesses w1 , w2 , especially in connection with extrusion. A sudden change ...

Abstract

The present invention relates to a method for producing a lightweight sheet-metal component with varying wall thicknesses w1, w2, characterized by the following method steps: extruding a lightweight metal to form a profile (1) with a non-planar profile cross section, wherein the wall thicknesses w1, w2 of the profile cross section differ from one another in at least two regions, cutting the profile (1) to length into profile pieces, widening the profile pieces, forming the flattened profile piece into a three-dimensional shaped sheet-metal component (8), wherein the sheet-metal component (8) has at least two regions with wall thicknesses w1, w2 that are different from one another.

Description

technical field [0001] The invention relates to a method for producing light metal components with different wall thicknesses according to the features of claim 1 . Background technique [0002] Motor vehicle structural parts and body components are used for the production of motor vehicle bodies. These components are produced at least from sheet steel, so that on the one hand there is sufficient freedom of shaping and on the other hand sufficient strength is achieved. Here, the production method usually provides that a sheet metal is provided, which is introduced into a forming tool, in particular a press-forming tool, and then press-formed, so that the sheet metal component is finally formed into a motor vehicle component. [0003] With the constant demand for lightweight construction, motor vehicle components and especially motor vehicle structural components are produced by hot forming and press hardening in order to reduce the specific weight of the component while usi...
