Definitions
- the invention relates to a method and a rolling mill for producing the Width of any strip-shaped rolling stock having any thickness profile by longitudinal rolling a starting material, in particular a metal strip or Circuit board.
- profile rolling includes rolling processes for the production of Semi-finished products with different thicknesses across the width of the rolling stock have long been known. This is done with appropriately calibrated rolls in several rolling processes (Stitches) creates the desired cross section. However, this type of manufacture is limited to rolling stock with a small width / thickness ratio. It is not very flexible there Correspondingly calibrated roller sets are almost always required for each cross-section become.
- the invention has for its object a method and a rolling mill to create the type mentioned, with which the disadvantages mentioned avoid and variable any profiles without additional effort can be manufactured flexibly.
- This object is achieved with a method according to the invention in that the Starting material with several staggered in the rolling direction, over the Rolling stock width of different depths penetrating into the starting material Width direction is deformed.
- the offset according to the invention in the rolling direction arranged one behind the other, almost only deforming in the width direction on the Rollers acting on the starting material enable a corresponding to the desired Profiling locally targeted deformation, the penetration depth of the depends on the respective employment of the individual narrow rollers or rollers.
- the starting material is ferrous or Non-ferrous metals as well as hot or cold working and at a Cold forming the starting material is a hot or cold strip.
- the starting material can be used one way or be deformed in a reversing manner, an embodiment providing that the Starting material is moved back and forth under the rollers.
- the respective The operating mode depends on the profiling and / or the degree of deformation required and possible with a stitch.
- the support pad which is a reciprocating one Table, alternatively, be a large diameter lower roller can, exerts no deformation forces on the starting material and serves Basically only as a supporting element for the rolling stock and counter holder for the Spinning rollers. These can advantageously be designed as full rolls.
- An alternative embodiment of the invention provides multi-part, from a basic body and a profile ring existing spinning rollers.
- the multi-part offers opposite Full rolling has the advantage of the base body to be used repeatedly (axis, shaft), on the worn out profile or push ring in the roller workshop can be exchanged for a new one.
- the profile ring is advantageous axially is displaceably arranged on the base body, the location of the action can be specifically shift to the starting material for its deformation in the width direction. The same naturally applies to axially displaceable full rolls.
- the support over its width a different surface texture. This can be done by roughness deviating from one another or a different or area-wise Lubrication to facilitate easier deformation in the width direction.
- the pressure rollers can also be assigned Heaters contribute. For this, e.g. a laser in front of each pressure roller or provide induction heating.
- the profile rolling unit is followed by a smoothing stand, so that a smooth structure creates a step structure created by the spinning rollers can be eliminated.
- a strip-shaped rolling stock having any thickness profile over the width from a starting material, such as a plate 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 in FIG. 4 below the output board 1 with a cross-section 4, the desired thickness profile is set over the rolling stock width b 0 (see FIG. 1).
- a plurality of spinning rollers 5, a support roller in the form of a large diameter lower roller 6 (FIGS. 1 to 3 and 7) or one in the rolling direction 7 (see the arrow in FIG. 1) are movable back and forth, in Fig.
- table 8 comprising the rolling unit 9 or 10 offset in the rolling direction 7 and set at different depths across the width of the rolling stock.
- the deformation of the strip-shaped rolling stock (plate 1 or metal strip 2) by means of the spinning rollers 5 occurs almost only in the width direction 11 without substantial elongation (cf. the arrows in FIG. 6 or the arrows in FIG. 4), for which the ones in FIG. 5 for a single pressure roller 5 geometry with the determining variables roller radius r R , working angle ⁇ , smoothing angle ⁇ , working radius ⁇ and contact length l B contributes.
- the starting material 1 or 2 By arranging several of these pressure rollers 5 in the longitudinal or rolling direction 7, offset across the width of the rolling stock and set at different depths, as shown schematically in FIG. 6, the starting material 1 or 2 according to the schematic drawing according to FIG. 6 step-shaped, with any thickness distribution deformed in the width direction 11.
- a circuit board 1 or a metal strip 2 with the width b 0 (initial dimension) becomes, for example, a transverse profile with the width b 1 (cf. FIG. 1) with a groove 4 (cf. FIG. 4) in the middle. Due to the large diameter lower roller 6 or the table 8, large-area support is achieved in the deformation of the starting material (board 1, metal strip 2).
- the lower roller 6 or table 8 can be lubricated over its width with different surface properties or differently.
- the effect of the pressure rollers 5 for deforming the starting material or rolling stock in the width direction 11 can be further favored in that a heater 12 is arranged in front of the pressure rollers 5, as indicated very schematically in FIG. 6.
- a smoothing stand 13 connected downstream of the rolling unit 9 (or rolling unit 10) in the rolling direction 7 and schematically drawn in for the exemplary embodiment according to FIG. 1 eliminates the step structure (cf. due to the pressure rollers 5 penetrating into the rolling stock at different depths.
- the rolling process runs in one direction only, i.e. that according to the rolling direction arrow 7.
- the metal strip 2 to be profiled runs there from a decoiler 14 and becomes after profiling by the pressure rollers 105 - only one of which is shown here is - wound up from a reel 15 to form a bundle.
- the spinning rollers 105 are multi-part compared to the full rolls of the above-described pressure rolls 5 trained and consist of a base body 16 and one thereon mounted profile or push ring 17, with the geometry shown in Fig. 5 is provided and can be axially displaceable.
