Embodiment Construction

[0019] A known (not shown) device for cold roll forming of profiles of variable cross-section comprises: a unit for cutting the metal strip along its width; a drive unit for the metal strip and a forming unit.

[0020] The forming unit comprises the known row of adjusting supports each having a roller support comprising a pair of rollers between which the metal sheet strip is guided along its length. The roll holders are translated transversely to the length of the sheet metal strip during cold roll forming and are moved and moved rotationally about the axes of the roll holders in order to deform the sheet metal strip into profiles of variable cross-section. The rollers of the roller stand are usually axis-parallel to each other, but the axes of the rollers can also be slightly inclined to each other with diameters that can vary in the longitudinal direction.

[0021] The following description is given with the aid of a variable-width profile, wherein the adjustment bracket is...

Abstract

The invention relates to a system for cold roll profiling profiles having variable cross-sections, comprising a plurality of roll stands arranged in a row, each comprising a pair of rolls, between which a sheet metal strip (2) is guided according to the length (X), wherein the roll stands are moved translationally transversely to the length of the sheet metal strip during cold roll profiling and are moved rotationally about an axis of the roll stand. According to the invention, a reforming device (8, 10, 12) is arranged behind at least one of the roll stands and has at least one drive for generating a movement of the reforming device in a plane transversely to the length (X) of the sheet metal strip.; On the basis of data calculated from data relating to the material and thickness of the sheet metal strip, the configuration and control data of the roll stands and the CAD data of the profiles to be shaped, the drive is controlled in such a way that, during ongoing operation of the system, the reforming device automatically cancels any shape deviations in the sheet metal strip leaving the at least one roll stand.

Description

technical field [0001] The invention relates to a system for cold roll forming of profiles of variable cross-section according to the preambles of claims 1 and 11 . Such systems are disclosed in German patent applications DE 10 2007 059 439.0, DE 100 11 755 A1, DE 2004 040 257 A1 and US 3 051 214 A, the contents of which are incorporated herein by reference . Background technique [0002] Profiles with a length-variable cross-section are produced with the aid of a system in which the roller stands or the adjustment supports supporting them are not only moved transversely to the longitudinal direction of the profile during forming, but the roller tools of each adjustment support are moved over the entire The profile length is positioned tangentially with respect to the desired flange extension line of the profile. For this purpose, in addition to an adjustment possibility transverse to the longitudinal direction of the profile, a rotational movement about an axis perpendicu...
