Benefits of technology

[0014]Advantageously, the material thickness of the at least one thickened region corresponds to 1.1-2 times of the initial material thickness of the rolling stock the profile is formed of. This insures an advantageous improvement of the stiffness of the material-optimized profile.

Embodiment Construction

[0020]A profile 11 according to the present invention, which is shown in FIGS. 1-2, has a C-shaped cross-section with two, extending parallel to each other, side walls 12 and a connection section 13 that connects the two side walls 12 with each other. A bend 17 is provided between each of the side walls 12 and the connection section 13. The free ends 14 of the side walls 12 are bent inward and, thus, have each a bend 18. The side walls 12 partially enclose a hollow space 19. The profile 11 extends along a longitudinal axis 15.

[0021]The profile 11 is formed of a strip-shaped rolling stock with an initial material thickness W and has two thickness-reduced sections 16 in the two side walls 12, respectively. The thickness-reduced sections 16 have a material thickness D that is smaller than the initial material thickness W. On opposite sides of each of the thickness-reduced sections 16, there are provided thickened regions 21, 22, respectively, which are formed by material accumulation a...

Abstract

A profile formed of a strip-shaped rolling stock and including at least one thickness-reduced section (16) having a thickness (D) that is smaller than the initial material thickness (W) of the rolling stock, at least one bend (17; 18), and at least one thickened region (21, 22) provided in a region of the at least one bend (17, 18) and having a material thickness (H) greater than the initial material thickness (W) of the rolling stock the profile (11) is formed of.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a profile formed of a strip-shaped rolling stock having an initial material thickness and including at least one thickness-reduced section having a thickness that is smaller than the initial material thickness of the rolling stock, and at least one bend.[0003]2. Description of the Prior Art[0004]Profiles, such as used, e.g., in the mounting or installation technology, are produced, e.g., from a strip-shaped rolling stock by deformation in a rolling plant. The profiles can have a round, polygonal, or C-shaped cross-section.[0005]In order to reduce the costs of a material, U.S. Pat. No. 4,233,833 suggests, e.g., to reduce thickness of at least one section of the rolling stock so that the material thickness in the thickness-reduced region is smaller than the initial material thickness of the strip-shaped rolling stock. With the thickness reduction, which is carried out by a cold rolling pro...
