Definitions

  • the invention relates to a pair of rollers for low-tolerance rolling of strand-shaped profiled rolling stock with at least one caliber channel rollers, which are provided with mutually supporting jacket sections, which are pressed against each other with a pre-tensioning force substantially exceeding the rolling force, and in which deformations of the one another by means of changes in the pre-tensioning force supported jacket areas of the rollers and thus changes in the caliber enclosed by them.
  • a change in the elastic flattening of the supporting surfaces of the rolls running on one another is to be effected by changing the prestressing force, so that the caliber formed between the rolls and thus the dimensions of the rolling stock can be influenced, and the change in the prestressing force should also be used as a manipulated variable direct control can be used.
  • it proves to be disadvantageous in such adjusting or regulating processes that the achievement of changes in the distance of the rolls by changing the roll flattening of the regions supported against one another requires considerable actuating forces and thus the pretensioning force is disadvantageously high above the rolling force, so that the design of the these extremely high forces must be taken into account in the respective scaffolding.
  • the invention is therefore based on the object of creating an arrangement of rollers of the type described, in which, on the one hand, mutual support of the rollers via the additional prestressing support surfaces makes them largely independent of the expansion of the scaffold and thus a steep spring characteristic thereof can be achieved, on the other hand, however, there is the possibility of noticeably influencing the dimensions of the rolling stock by means of relatively small changes in the additional prestressing force, with simple control being possible for the adjustment, however, if necessary additionally, a thickness control using the prestressing forces as actuating forces is not excluded.
  • a work roll 1 is shown in half section, on the one roll pin 2 of which a drive pin 3 is connected for receiving the coupling body of a drive spindle.
  • a caliber channel 4 is provided in the center, which practically determines one half of a caliber.
  • wings 5 adjoin each other, which have the cylindrical jacket-shaped support surfaces 6, by means of which the two essentially identical rollers of a pair of rollers are braced against one another, and by means of which they support one another, mutually under the action of the applied pretensioning force.
  • the wings 5 and thus the support surfaces 6 are designed to a certain extent to be elastic, in that each wing 5 is gripped by a recess 7 and a decoupling groove 8 is provided between the caliber channel 4 and the support surface 6. Between the grooves 8 and the caliber channel 4 there are still delimiting surfaces 9 which essentially laterally close the caliber. However, they withdraw slightly from the support surfaces 6, so that the support within the elastic region of the support surfaces 6 of the wings 5 takes place solely via the support surfaces and the boundary surfaces do not impair the elastic deformation.
  • the rollers are used in stands, as are known, for example, from DE-34 33 300-A.
  • the rollers of a pair of rollers are pressed against one another by means of a preload force F v which significantly exceeds the rolling force F w , so that their supporting surfaces lying on and rolling on one another take over the difference between the preload force F v and the rolling force F w .
  • the biasing force is increased, the wings 5 and thus the support surfaces 6 elastically yield to a much greater extent than this would previously have permitted the roller pressure occurring on the support surfaces when the force was taken over. Larger adjustment or control ranges can thus be achieved without the prestress increasing the rolling force having to be set high, or even the stand having the rolls having to be dimensioned stronger with regard to peaks of the prestressing force than is necessary for the rolling process itself.
  • the direct support compensates for expansion of the stand, so that there is a relatively stiff characteristic of the stand suspension and thus a largely constant caliber, which enables a low-tolerance rolling.
  • the dimension of the caliber and thus the rolling stock produced can be changed by means of relatively low additional prestressing forces, so that these dimensions can be controlled and / or regulated to a certain extent.

Claims (3)

  1. Paire de cylindres pour laminage avec faibles tolérances d'un produit laminé profilé en forme de barre, qui comprend des cylindres comportant nu moins une cannelure (4) et des secteurs d'enveloppe qui prennent appui les uns sur les autres et sont poussés les uns contre les autres par une force de précontrainte (FV) nettement supérieure à la force de laminage (FW) et dans laquelle il est possible, en modifiant la force de précontrainte (FV), de produire des déformations des secteurs des enveloppes des cylindres qui prennent appui les uns sur les autres et, de ce fait, de modifier la forme de la cannelure qu'ils délimitent entre eux, caractérisée en ce que les secteurs d'enveloppe qui prennent appui les uns sur les autres peuvent,en raison de la présence d'évidements 7, se déformer élastiquement sous l'action de la force de précontrainte (FV) et, de ce fait, par les rainures (8) placées des deux côtés de la cannelure (4) sont désaccouplés de la partie rigide.
  2. Paire de cylindres selon la revendication 1, caractérisée en ce que la cannelure (4) et les rainures (8) délimitent des surfaces annulaires (9), en ce que les secteurs d'enveloppe constituées par des surfaces d'appui cylindriques (6) sont situées de part et d'autre de la cannelure (4) à l'extérieur des surfaces annulaires (9) et en ce que le diamètre des surfaces d'appui (6) est légèrement supérieur à celui des surfaces annulaires.
  3. Paire de cylindres selon l'une des revendications 1 ou 2, caractérisée en ce que les rainures (8) ont un profil sensiblement semi-circulaire.
