Description

The present invention relates to a device for cold roll profiling of a sheet metal to a profiled sheet with a novel arrangement of forming elements.

A device and a method for producing a profiled sheet, such as a U-profile with constant height and variable width are from the JP 61086031 A known. The device includes a desired width profile predetermining lower mold strip for full-surface planar support of a bottom of the desired U-profile and two horizontally movable tapered rollers for bending the protruding from the molding profile sheet metal parts, ie later sheet metal leg, by roll forming. The mold bar is pulled together with a semi-finished product resting thereon on a carriage between forming rollers. After replacing first forming rollers against second tapered forming rollers, the process is repeated. The tapered rollers are arranged so that they press the semifinished product from above against the lower molding, that this only in the horizontal direction, for example, must be fixed by two positioning holes. This device only allows the production of profile sheets or U-profiles with variable width and level bottom.

DE 10 2009 022 829 B3 discloses a device for cold roll profiling of the sheet, which is clamped between bar-shaped clamping means or clamping elements which are adapted to a desired profile and optionally also have a variable cross-section, to then be passed together with the clamping elements by stationary forming rollers of the device. The clamping elements press and shape the sheet, which is also laterally deformed by the forming rollers. Here, the clamping elements and the forming rollers must be specially adapted to the profile to be produced and these are replaced in each case in a production of different profile sheets.

The cold rolling profiling of U or Hut profiles with variable height is indeed possible without the use of forming or supporting strips, such. B. from the DE 10 2007 059 439 B3 known, but you need in addition in each side roller stands for molding the profile legs a number of adjustable rollers for forming the profile sheet.

WO 2016 079 210 discloses an apparatus for cold rolling profiling of the sheet according to the preamble of the independent claim. In this case, the sheet is held clamped by a first and a second clamping means, which are terminal strips, clamped in a clamping region of the sheet so that a sheet leg protrudes laterally, which is formed by a roll forming unit with a forming roll when the Rollformeinheit side of the chucking passes or is passed. Alternatively or additionally, the clamping means can be passed or moved past the rollforming unit. By the roll forming unit and the clamping means are driven accordingly against each other, a variable profile sheet can advantageously be produced with a variable along a longitudinal axis of the profile sheet cross-sectional profile. However, as increasingly thicker or harder sheets of iron, steel or other hard metals are transformed, increase the mechanical requirements of the rollforming unit increasingly. Even if an outer region of the sheet-metal leg is to be scratched as little as possible by the forming, coatings are very expensive.

The invention is therefore based on the object to provide a device for a cold roll profiling of profile sheets with in particular a variable cross-sectional profile, the apparatus should be as compact as possible and stable and thereby inexpensive. Preferably, the widest possible variety of profile sheets should be able to be produced with the inventive device with little effort.

This object is achieved by a device for cold roll profiling of a sheet having the features of independent claim 1. Advantageous developments of the invention are specified in the dependent claims.

In the cold rolling profiling apparatus according to the present invention, a sheet is clamped and held between a first chuck having a longitudinal edge and an opposed second chuck in a clamping portion of the sheet such that a sheet leg of the sheet projects laterally from the edge, supported on the edge and can be bent over. Further, in the apparatus, a first forming roll rotatably formed around a first rotation axis as a first forming element is arranged to be movable against the first and second clamping means in the longitudinal direction, the first forming roll moving past the edge comes in contact with a first portion of the sheet-metal leg and transforms the first section. According to the invention, the device has at least one second forming element, which is arranged on a same side of the sheet and in the direction of the longitudinal axis in a same longitudinal region as the first forming roll to at least partially in contact with to be a second portion of the sheet-metal leg and to transform this or move in passing, wherein the second portion extends in the longitudinal direction and the outside of the first portion and lies outside of a forming region of the first forming roller. In this case, the respective second deformation element or a respective second axis of rotation of the respective second deformation element is rigidly coupled to the first axis of rotation of the first forming roller. Thus, the first forming roller is rotatably decoupled from the second forming element in a rotation about its first axis of rotation.

By the first forming roller contacts and deforms only the first portion of the sheet leg and not, as in the prior art, also at the same time the second portion of the sheet leg, the first forming roller is correspondingly narrower than in the prior art and as it would be necessary if at the same time the second section of the sheet-metal leg would have to be covered. In general, occur during the deformation of the metal leg along edge of the first clamping means and thus on the first forming the highest forming forces, which are executed largely radially to the center of the first forming roller and thus at the first axis of rotation, where the first forming roll or is held, create a bending moment. For example, an approximately twice the bending moment is generated in a twice as wide first forming roller, which must be held in order to keep the first forming roller in its predefined position. Therefore, it is therefore very advantageous to make the first forming roller as narrow as possible and to form the bearing provided for this or an attachment for the bearing of the first forming roller as close as possible to the radial force or the first forming roller.

In this case, the second section of the sheet-metal limb is reshaped or guided by the at least one second shaping element, which is preferably at least one second forming roller. Preferably, the respective second forming element is smaller in diameter than the first forming roller and is disposed over the first forming roller. Alternatively, the second forming element may also partially cover the first section of the sheet-metal limb, if it is arranged somewhat laterally, by lying against the first section and not touching the first forming roller.

It is advantageous in the inventive division of a wide forming roller, as would correspond to the prior art, which covers the first portion and the second portion of the sheet in the first forming roller and in the second, preferably smaller forming element that the second forming element significantly less space claimed as it would be possible with a correspondingly wider forming roller from the prior art.

It is also advantageous in the division according to the invention, when the respective second forming element is formed as a respective second forming roller, that the respective second forming roller is not rotationally coupled directly to the first forming roller, so that a surface of the sheet is less rubbed or scratched in the second section as would be the case if the first forming roll directly contacted the second section. This is particularly the case when the first forming roller drives the sheet in the longitudinal direction and therebetween prevails a slip.

Preferably, the second forming element is a second forming roller, wherein the second forming roller is rotatably decoupled from the first forming roller. A coupling consists only of the clamped between sheet metal, for clarity.

The invention allows a cold roll profiling or shortly called profiling of a sheet to form moldings and in particular to U-profiles or hat profiles, L-profiles or Z-profiles or other types of profiles. For clarity, the term profile is synonymous with the term profile sheet or sheet profile.

The invention makes it possible to produce profiles with a constant height and / or width, that is to say with a constant cross section.

A preferred embodiment of the invention also allows the production of profiles with variable height and / or variable width and thus a variable in the longitudinal direction of the profile cross-section. In particular, a profile can be produced in which at least one sheet-metal leg has a shape that is not flat everywhere.

Preferably, the second forming element is rigid but adjustable to the first axis of rotation of the first forming roller. As a result, the profile in the second section of the sheet can be finely adjusted, and stresses in the sheet can be counteracted. Preferably, the adjustment is adjustable by actuators, so that the sheet can be readjusted in the first section and in the second section during the ongoing process. Preferably, the first forming roller can be adjusted while quasi simultaneously adjusting the respective second forming element. For clarity, it is meant rigidly that the respective second forming element remains in a predefined position relative to the first forming roll, and the respective second forming element and the first forming roll preferably form a forming cluster unit.

Another advantage of the present invention is that it is ...
