Benefits of technology

[0009] One important advantage of the inventive construction component or structural member is its inherent rigidity and stability, and its easy integration in a vehicle body shell. The construction component, which is shaped using roller profiling, exhibits very good structural characteristics both in the highly stressed edge area of the profile cross-section as well in the roller profiled flange. These structural features have a positive influence on the ability of the construction component to resist stress, in particular cyclic stresses.
[0037] For example, beams of the A-, B-, C- or D-column structures in motor vehicle construction must be produced with high quality and with high dimensional accuracy in high numbers. The inventive construction component exhibits very good surface quality, high dimensional accuracy and an improved ability to be incorporated into the body shell.

Problems solved by technology

These construction components have been found to be unsuitable for complex vehicle-reinforcing structures.
Even these construction components have been found not to be suitable for certain complex vehicle structures.

Embodiment Construction

[0041]FIG. 1 shows an illustrative embodiment of an inventive construction component 1. This shape is conventionally referred to as “hat” or “omega” profile. The construction component 1 is made of TRIP-steel, which is supplied as a starting material in the form of a roll. The starting material is profiled or shaped from a planar condition into the construction component 1 in a roller profiling device. The roller profiled construction component 1 exhibits a base 2 and opposing sidewalls 3 with flanges 4. These sidewalls 3 transition to the base 2 via a bowed or curved area 5. Further, the construction component 1 exhibits oppositely lying flanges 4 respectively radiating out from the sidewalls 3, which flanges are produced by roller profiling. The sidewalls 3 transition via flange curves 6 into the flanges 4. The flanges 4 end with edges 7. The sidewalls 3 are so dimensioned, that openings can be introduced which make possible the passage through of an electrode of a welding rod or ...

Abstract

The invention concerns a construction component (1) profiled using roller profiling, with a profile cross-section changing in the longitudinal extent, wherein the profiled construction component includes a flange (4). The construction component having this shape is rigid and particularly easy to integrate into the vehicle body shell.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention concerns a construction component with a longitudinally changing cross-section shape according to the precharacterizing portion of patent claim 1. [0003] 2. Related Art of the Invention [0004] It is well known to have construction components with longitudinally extending profiles, produced by bending a ribbon or strip of supplied raw material by roller profiling to form a profile having a continuous even cross-section, in particular a U-shaped profile cross-section. These construction components have been found to be unsuitable for complex vehicle-reinforcing structures. [0005] DE 100 11 755 A1 teaches a construction component having a profile having a changing longitudinal cross-section, in particular a U-shaped profile cross-section. This construction component is produced in a roller bending device. The construction component includes a base and opposing sidewalls, wherein, beginning with a particul...
