Definitions

  • the invention relates to a method and a device for the stretch straightening of Cold strip with the features specified in the independent claims.
  • Such a method and such a stretch bending apparatus are known from the US 5,704,237 A known.
  • EP 0 393 301 B2 is a method for continuous Drawing of metallic strips with a strip thickness between 0.05 mm and 0.5 mm, in particular bands of steel, aluminum or the like Metals have become known. There passes through the straightening band one Brake roller set and a Switzerlandrollensatz and is between two sets of rollers subjected in the course of his stretching in the plastic area to a stretch train, which corresponds to the yield strength of the strip material or these Yield point slightly exceeds.
  • the band is formed by superposition of Bandzug and bending in the casserole or expiration point of the tape on the individual Rolls of the Hochzug roller set plastically extended. It can thereby be a point-symmetrical structure of the bends in the other set of rollers reach, especially with thicker bands, not by pure train between the rolls can be stretched.
  • the band with short 'guy length between the respective departure and run points of the individual Rolls passed through the roller set.
  • the tape is improved and reduces the tendency of the band to form longitudinal folds.
  • the short guy length can be achieved, for example, that in the direction of the wrap or the band pass successive roles of the roller set have a smaller distance from each other than that in conventional S-roll arrangements is the case.
  • a preferred measure provides that the degree of stretching regulated as follows is that in which arranged between the brake and the Werrollensatz another set of rolls the Einzelstreckgrade in the up and down points the individual roles are summed up to a cumulative degree of what are the degrees of stretching outside of the set of rollers between each of the Train building and judging or the judging and the train dismantling Rolls of the brake and Werrollensatzes tapped and on the Torques of the rollers of the further roller set are returned. It Thus, a difference speed is no longer required between the rollers, which finally gives a required degree of stretch behind two rolls, Rather, this scheme allows meaningful distributions of the individual degrees of stretching to reach.
  • An embodiment of the invention provides that the tension rollers of the further roller set a different diameter than the rollers of the brake and Werrollenasta have.
  • By changing the roll diameter may be due a specifically set speed difference the plasticization of the Bandes and thus the achievable or adjustable degree of stretching can be influenced.
  • the inner two In a set of four-roller reels, only the inner two can be used Pull rollers or all four roles with the remaining roles, i. to those the brake and Werrollensatzes deviating roll diameters provided become. If these roles compared to the other roles a smaller Diameter own, can be with decreasing diameter the greater the resulting degree of stretch when bending the tape with superimposed Reach train. The boundaries are where the tape surfaces are damaged could become. For very sensitive tape surfaces results a minimal impact on rather larger roll diameters, e.g. from 800 to 1500 mm.
  • a plant 1 for stretch straightening of Regenbändem 2, preferably with Thicknesses above 0.5 mm, according to FIG. 1 consists of a brake roller set 3 and - seen in the direction of the tape passage marked by arrows following this - another, subsequently high-tensile roll set 5 Roll set and a Switzerlandrollensatz 4.
  • the brake roller set 3 is with four rollers 6 and the Werrollensatz 4 formed with four rollers 7, respectively arranged in pairs S-shaped.
  • the Hochzug roller set 5 also has four roles, also in pairs
  • the upper pair of rollers 8a, 8b and the lower pair of rollers 9a, 9b is on the one hand in relative to the individual roles to each other and on the other hand of pair of rollers Pair of rollers arranged as close together as possible. It will be so a short guy length 10, each between the drain point 11 of preceding in the direction of tape travel to the roll following in the direction of tape travel defined, whereby the tape improves and the training of Longitudinal folds (towel effect) is reduced.
  • the band 2 in the pull-up roller set 5 of an alternating bend - with only one existing pair of rolls definitely subjected to a bend - turns into the pull-up roller set 5, a degree of stretching increased by the bending of the tape under tension one.
  • the resulting due to bending of the belt 2 with superimposed train The degree of stretching becomes greater, the smaller the diameter of the rollers.
  • the limits are where a small roll diameter disadvantageous sensitive tape surfaces, because a rather large roll diameter, e.g. 800 to 1500 mm, minimizes the influence.
  • the Roll diameter are selected, so in any case creates a plastic Extension of the band 1 by superposition of strip tension and bending in the Casserole or drain point 11, 12 of the rollers 8a, 8b and 9a, 9b.
  • the control scheme shown allows the degree of stretching by the mutual Influence of the individual degrees of stretch in the up and down points 12 or 11 of the rollers in the high-tension roller set 5 to a total degree of stretching add up. It is provided with a suitable pilot control and regulation of Single torques reaches a desired degree of stretch.
  • the degree of stretching will be outside the Hochzug roller set 5 between the train building and judging roles or the directing and the train dismantling roles of Brake and Werrollensatzes 30 and 40 tapped and on the torques the roles of Hochzug roller set 5 returned. It will be so a meaningful distribution of the individual degrees of stretch possible.
