Definitions
- the invention relates according to claim 1, a method and according to claim 7 a rolling mill for the production of the Width of any thickness profile strip-shaped rolling stock by longitudinal rolls a starting material, in particular a metal strip or a Board (see for example DE-A 3 622 926).
- roller forming are finally rolling processes for the production of semi-finished with different thickness over the Walzgutbreite long known. This is done with appropriately calibrated rollers in several rolling operations (Stitches) produces the desired cross-section. This type of production is but limited to rolling stock with a small width / thickness ratio. It is little flexible, because for each cross-section almost always correspondingly calibrated sets of rollers needed.
- the invention is based on the object, a method and a rolling mill of to create the aforementioned type with which to avoid the disadvantages mentioned and any profiles without additional effort variable and flexible let produce.
- This object is achieved by a method according to the invention in that the starting material with a plurality of successively in the rolling direction in the transverse direction arranged staggered over the Walzgutbreite different deep into the Starting material penetrating -Druckwalzen is deformed in the width direction.
- the starting material in the one-way operation or reversibly deformed wherein an embodiment provides that the starting material is moved back and forth under the rollers.
- the respective Operating mode depends on the profiling and / or the required and with a stitch possible degree of deformation.
- a rolling stock receiving support upper in succession in the rolling direction offset in the transverse direction, different salaried spinning rollers assigned.
- the support pad which is a back and forth Table, alternatively a large diameter lower roller can act, exerts no deformation forces on the source material and basically serves exclusively as a support element for the rolling stock and counterhold for the spinning rollers.
- An alternative embodiment of the invention provides multipart, from a body and a profile ring existing pressure rollers before.
- the multi-part offers compared to full rolls the advantage of repeatedly used body (Axle, shaft), on which in the roller workshop a worn profile or Push ring can be easily replaced with a new one.
- the profile ring is advantageously arranged axially displaceably on the body, can be the location of the action on the starting material for its deformation in the width direction shift specifically. The same naturally applies to axially displaceably mounted Full rolls.
- the support pad can be over its width with a different surface finish. This can be done by different roughness or a different or regional Lubrication for the purpose of facilitated deformation in the width direction happen.
- Heating devices contribute. For this purpose, e.g. in front of each spinning roller a laser or provide induction heating.
- the profile roller unit is followed by a screed, so that a step pattern produced by the spinning rollers is formed by a smoothing pass eliminate it.
- a band-shaped rolling stock having a thickness profile of any desired thickness from a starting material, such as a board 1 shown in FIG. 4 or a metal strip 2 shown in FIGS. 1 and 7, to form a profiled finished product 3, for example that shown in FIG. 4 below the output board 1 with a groove 4 generated transverse profile
- the desired thickness profile over the Walzgutbreite b 0 (see Fig. 1) is set.
- a plurality of spinning rollers 5 are also provided, and a support pad in the form of a large diameter bottom roller 6 (FIGS. 1 to 3 and 7) or a roller 7 (see the arrow in FIG. in Fig.
- table 8 comprising roller unit 9 and 10 are arranged offset in the rolling direction 7 and employed different depths over the Walzgutbreite.
- the deformation of the strip-shaped rolling stock (blank 1 or metal strip 2) by means of the spinning rolls 5 takes place without significant elongation almost exclusively in the width direction 11 (compare the arrows in FIG. 6 or in FIG. 4), for which the in FIG for a single pressure roller 5 shown geometry with the determining variables roller radius r R , working angle ⁇ , smoothing angle ⁇ , working radius ⁇ and contact length I B contributes.
- lower roller 6 or table 8 may be lubricated over their width of different surface finish or differently.
- the effect of the pressure rollers 5 for deformation of the starting material or rolling stock in the width direction 11 can be further promoted by the fact that before the spinning rolls 5 each a heater 12 is arranged, as indicated very schematically in Fig. 6.
- the rolling process is only one-way, i. the according to rolling direction arrow. 7
- the metal strip 2 to be profiled runs there from a discharge reel 14 and becomes after profiling by the spinning rollers 105 - only one of which is shown here is - wound by a winding reel 15 again to a bunch.
- the spinning rollers 105 are compared to the solid rollers of the above-described spinning rollers 5 in several parts formed and consist of a base body 16 and a thereon raised profile or pressing ring 17, with the geometry shown in Fig. 5 is provided and can be axially displaceable.
