Definitions
- the invention relates to a method for producing a sheet with a surface structure of sharp-edged, rib-like elevations, wherein a sheet metal strip with the aid of a surveys corresponding Vertiefun ⁇ conditions, forming rollers is rolled and then civil ⁇ is unpulsed before after unwinding of the reeled Federal the tin band is addressed and expanded / elaborated.
- the form- - giving rolled sheet metal strips are wound into coils to transport them before their further processing and intermediate storage.
- the coiling of the metal strips after their development, requires a straightening process with the aid of straightening rolls.
- the straightening forces occurring attack the rib-like elevations of the metal strips, so that sharp edges of the surveys are inevitably rounded.
- a sharp-edged formation of the surveys is crucial for a high level of skid resistance.
- the invention is therefore based on the object, a method for producing a sheet with a surface structure of sharp-edged rib-like elevations of the type described in such a way that the formed after rolling, sharp-edged elevations obtained when straightening the sheet metal strip after unwinding from a bunch ,
- simple conditions are to be created in order to allow the rolling fluid to flow out of the region of the elevations during the shaping of the roll and thus avoid the formation of stains.
- the invention solves the problem set by the fact that during the forming rolling of the metal strip in the rib-like elevations at least an excessive approach for receiving the straightening forces is formed and that when straightening the unwound metal strip, the excessive approaches are compressed by the straightening forces plastically to a height that at least equal to the height of the surveys.
- the elevations during straightening of the sheet-metal strip can be relieved of the straightening forces which act on the elevated elevations and these deform plastically, so that the sharp-edged contour of the rib-shaped Erhe ⁇ exercises during the straightening process is maintained.
- the prerequisite for this is that the excessive projections are compressed during the straightening process at most to a height corresponding to the height of the rib-like elevations, otherwise a mechanical stress on the rib-like elevations occurs with the risk that the sharp edge is lost.
- the raised shoulders should project slightly beyond the rib-shaped elevations so as not to adversely affect the skid resistance due to the excessive elevations.
- the deepening provided for forming the raised projections in the roll shell can have a depth which is greater than the height of the formed über ⁇ elevated approaches, so that between the bottom of these wells and the excessive projections remains a free space in which the rolling fluid can be displaced from the region of the rib-like elevations.
- the excessive elevations In order to be able to make good use of the sharp-edged elevations for the desired skid resistance of the metal sheets, the excessive elevations must not form an impact surface substantially impairing the effect of the sharp-edged elevations. This succeeds in an advantageous manner, if the excessive approaches in Region of one end of the rib-like elevations are formed, because in this case the vast length of the rib-like elevations are available as not affected by the approaches appearances. If, for optical reasons, the rib-like elevations are formed symmetrically to their longitudinal center, then appropriate approaches are to be provided at both ends of the rib-like elevations.
- FIG. 1 shows a sheet metal rolled according to the method of the invention after a straightening process, in a detail, in a plan view of the structured surface
- FIG. 2 shows a projection formed by a shaping roller
- FIG. 4 shows a section along a recess of a rolling shell for the formation according to the invention of a rib-like elevation
- 5 shows a representation corresponding to FIG. 2 of a construction variant of an elevation for forming a structured sheet metal surface
- FIG. 6 shows a section along the line VI-VI of FIG. 5.
- a sheet metal 1 produced by the method according to the invention has a rolled surface structure with rib-shaped elevations 2 which form an, for example, triangular cross-section.
- the flanks 3 of these rib-like elevations 2 intersect sharp-edged in a back line 4.
- lugs 5 are provided whose height H slightly exceeds the height h of the rib-like elevations 2, as shown in FIG can.
- the surveys 2 at least take over part of the surcharge, the sharp-edged back line 4 of the elevations 2 for the slip resistance of the structured surface of the sheet 1, and not the lugs 5, which serve only to preserve the sharp edge of the elevations 2 during the manufacturing process of the sheet 1.
- FIG. 4 is a section through the mantle of a roll 6 used for patterning the sheet surface along a partial formge ⁇ reproduced recess 7 of the rib 'enartigen elevations 2.
- a recess 8 for forming the lugs 5 at.
- this depression 8 has a depth T which exceeds the height H ü of the projections 5 formed by the rolling process, as indicated in phantom in FIG. 4.
- the remaining between the among the among the among the among the among the among the among the among the among the among the among the among the among the among the among the among the several lugs 5 and the recess 8 space 9 serves to the rolling fluid used in rolling the surface structure of a metal strip during penetration of the rolling stock to displace into the recesses 7 and 8 in this space 9, in order to avoid a plaque-forming extrusion of the rolling fluid in the region of the resulting elevations 2.
- the lugs 5 are compared to a sheet metal 1 made from such a sheet metal strip according to FIGS Oversize of the height H u formed.
- the sheet metal strip Since the rolled sheet metal strip is generally unwound to form a bundle and unwound from this bundle before further processing, the sheet metal strip is to be straightened after unwinding, which is carried out with the aid of a dressing stand.
- the straightening forces acting on the metal strip via the straightening rolls would destroy the sharp-edged back line 4 in the event of an attack on the elevations 2.
- the excessive projections 5 are provided in the end region of the elevations 7, so that the straightening forces are transmitted via these approaches 5 on the sheet metal strip, under a plastic deformation of the excessive projections 5, which are thereby compressed to the height H.
- the sharp-edged elevations 2 therefore remain free from the action of the leveling rolls and retain their sharp-edged shape.
- FIGS. 5 and 6 show a different embodiment of the elevations 2 and the projections 5 relative to the embodiment according to FIGS. 1 to 3.
- the function of both the elevations 2 and the end-side lugs 5 remains the same. It is only sought a symmetrical to the longitudinal center of the rib-like elevations 2 appearance, but this can not be achieved with approaches that match the approaches 5, otherwise the tread support on the surveys 2 is at risk.
- projections 10 are provided on the ends of the elevations 2 opposite the projections 5, which have a contour shape corresponding to the projections 5, but have a height h a which is lower than the fin height h of the elevations 2.
- the invention is not limited to the illustrated perennialsbei ⁇ games.
- rib-like elevations 2 with corresponding projections 5 can be provided because it does not depend on the geometric shape of the elevations 2 and lugs 5, but rather on the fact that the over-elevated lugs 5 during the subsequent straightening of the rolled sheet metal strips sharp-edged elevations 2 remain substantially free of straightening forces.
