Description

The present invention relates to a device for cold roll profiling of a sheet metal to form a profiled sheet with the features of the preamble of claim 1.

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 S61-86 031 A famous. The device contains a lower shaped strip, which specifies the desired width profile, for full-surface flat support of a base of the desired U-profile, as well as two horizontally movable tapered rollers for bending over the profiled sheet metal parts protruding from the shaped strip, i.e. later sheet metal legs, by roll profiling. The molding is pulled through together with a semi-finished product resting on it on a slide between forming rollers. After replacing the first forming rollers with second, more conical forming rollers, the process is repeated. The tapered rollers are arranged in such a way that they also press the semi-finished product from above against the lower molding so that it only has to be fixed in the horizontal direction, for example through two positioning holes. This device only allows the production of profile sheets or U-profiles with variable width and flat bottom.

DE 25 21 620 A1 discloses a device for cold roll profiling of the sheet, which is constructed similarly to the features of the preamble of claim 1. Here, the sheet is passed to a profiling of the profiled sheet between several rollers, the bearing axes of which are arranged essentially in a plane that is perpendicular to a longitudinal axis of the sheet, and some of the rollers can be variably positioned in the plane.

DE 10 2009 022 829 B3 discloses a device for cold roll profiling of the sheet metal, 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, in order then to be passed together with the clamping elements through stationary forming rollers of the device. The clamping elements press and shape the sheet metal, which is also laterally formed by the forming rollers. Here, the clamping elements and the forming rollers have to be specially adapted to the profile to be produced and these have to be exchanged when different profile sheets are produced.

The cold roll profiling of U or hat profiles with variable height is also possible without the use of shaping or supporting strips, such as. B. from the DE 10 2007 059 439 B3 known, but you also need a number of adjustable rollers for forming the profile sheet in the respective lateral roller frames for forming the profile legs.

WO 2016/079 210 A1 discloses an apparatus for cold roll forming of the sheet metal according to the preamble of the independent claim. For example, the sheet metal is held clamped in a clamping area of the sheet metal by a first and a second clamping means, which are clamping strips, in such a way that a sheet metal leg protrudes laterally, which is formed by a roll forming unit with a forming roller when the roll forming unit is laterally attached to the clamping means drives past or is moved past. Alternatively or additionally, the clamping means can be driven past or moved past the roll forming unit. By moving the roll forming unit and the clamping means against one another in a correspondingly controlled manner, a variable profiled sheet with a variable cross-sectional profile along a longitudinal axis of the profiled sheet can advantageously be produced. However, since increasingly thick or harder sheets made of iron, steel or other hard metals are being formed, the mechanical demands on the roll forming unit are increasing. Even if an outer area of the sheet metal leg is to be scratched as little as possible by the reshaping, coatings are very expensive.

The invention is therefore based on the object of providing a device for cold roll profiling of profiled sheets with, in particular, a variable cross-sectional profile, the device being as compact and stable as possible in terms of apparatus and at the same time inexpensive. The device according to the invention should preferably be able to produce as great a variety of profile sheets as possible with little effort.

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

In the device according to the invention for cold roll forming, a sheet metal is clamped and held between a first clamping means, which has an edge running in the longitudinal direction, and an opposing second clamping means in a clamping section of the sheet metal so that a sheet metal leg of the sheet metal protruding laterally from the edge, can be supported on the edge and bent. Furthermore, a first forming roller, which is designed as a first forming element to be rotatable about a first axis of rotation, is arranged in such a way that it is positioned against the first in the device and second clamping means can be moved relative to one another in the longitudinal direction, the first forming roller coming into contact with a first section of the sheet metal leg as it moves past the edge and forming the first section. According to the invention, the device has at least one second forming element, which is arranged on the same side of the sheet metal and in the direction of the longitudinal axis in the same length range as the first forming roller in order to be at least partially in contact with a second section of the sheet metal leg and this when moving past to reshape or guide, wherein the second section runs in the longitudinal direction and adjoins the first section on the outside and lies outside a deformation region of the first deformation roller. The respective second forming element or a respective second axis of rotation of the respective second forming element is rigidly coupled to the first axis of rotation of the first forming roller. The first forming roller is thus rotationally decoupled from the second forming element when it rotates about its first axis of rotation.

Since the first forming roller only contacts and reshapes the first section of the sheet metal leg and not, as in the prior art, also the second section of the sheet metal leg at the same time, the first forming roller is designed correspondingly narrower than in the prior art and than would be necessary if at the same time the second section of the sheet metal leg would also have to be covered. As a rule, when the sheet metal leg is formed along the edge of the first clamping means and thus on the first forming roller, the highest forming forces occur, most of which are directed radially to the center of the first forming roller and thus to the first axis of rotation where the first forming roller is supported or is held, generate a bending moment. For example, in the case of a first forming roller that is twice as wide, approximately twice the bending moment is generated which must be maintained in order to hold the first forming roller in its predefined position. It is therefore very advantageous to design the first forming roller as narrow as possible and to design the bearing provided for this purpose or a fastening for the bearing of the first forming roller as close as possible to the radial force or the first forming roller.

The second section of the sheet metal leg is formed or guided by the at least one second forming element, which is preferably at least one second forming roller. The respective second forming element is preferably smaller in diameter than the first forming roller and is arranged above the first forming roller. Alternatively, the second forming element can also partially cover the first section of the sheet metal leg if it is arranged somewhat laterally in that it rests against the first section but does not touch the first forming roller.

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

In the case of the division according to the invention, it is also advantageous if the respective second forming element is designed 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 metal is less rubbed or scratched in the second section than would be the case if the first forming roller were to contact the second section directly. This is particularly the case when the first forming roller drives the sheet metal in the longitudinal direction and there is slippage between them.

The second forming element is preferably a second forming roller, the second forming roller being decoupled from the first forming roller in terms of rotation. There is only a coupling via the sheet metal clamped in between, for the sake of clarity.

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

The invention enables the production of profiles with a constant height and / or width, that is to say with a constant cross-section.

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

The second forming element is preferably rigid but adjustable with respect to the first axis of rotation of the first forming roller. This allows the profile in the second section of the sheet metal to be fine-tuned, and tensions in the sheet metal can be counteracted. The adjustment is preferably adjustable by actuators, so that the sheet metal in the first section and in the second section can be readjusted during the ongoing process. The first forming roller can preferably be adjusted and the respective second forming element can be adjusted at the same time as it were. For the sake of clarity, rigid means that the respective second forming element remains in a predefined position relative to the first forming roller, and the respective second forming element and the first forming roller preferably form a forming cluster unit.

Another advantage of the present invention is ...
