Definitions

  • the invention relates to a method for the continuous tensile stretching of thin strips, in particular of metallic strips made of steel, aluminum or the like.
  • the reduction in bandwidth in the transverse direction is hindered in particular because one uses as little as possible Wants to build up high stretching rollers and consequently uses rollers whose roller jackets are provided with a friction lining made of rubber, plastic or the like.
  • the last role of the brake roller set and the first role of the pull roller set have to transfer the maximum stretch on the belt according to a staggering of the coefficient of friction e ⁇ .
  • the stretching stretches generated are set such that the respective stretching limit or yield point of the band in question is reached between the last braking roller and the first tensioning roller and any lengthening of the band which can be set as desired.
  • the longitudinal stresses that occur here cause the aforementioned transverse stresses, which are dependent on the strip material.
  • the ratio of ⁇ cross to ⁇ longitudinal ', the so-called Poisson's coefficient ⁇ , is between 0.25 - 0.3 for metals.
  • the inner edges have slightly longer sides than the outer edges, which also disturbs. This effect is further enhanced by the fact that the band can press into the elastic coating of the roll shells, so that the band edges press into the roll shells more strongly in the edge region than in the middle band region.
  • the invention has for its object to provide a method and an apparatus for the continuous tensile stretching of thin strips, in particular of metallic strips, of the type described at the outset, according to which the strip transverse changes occurring during plastic stretching are reduced to a minimum and consequently the formation of central dishes and of over the bandwidth of unevenly distributed residual voltages can be almost eliminated.
  • the invention in a generic method in that the strip is only subjected to the drawing stretch required for stretching it in the plastic area in an intermediate drawing stretching roller pair between the braking roller set and the pulling roller set.
  • the invention teaches with independent importance that with the pair of tension stretching rollers about 5% - 25% of the maximum stretch for the plastic stretching and with the brake roller set and tension roller set 75% - 95% of the maximum stretching for the elastic stretching of the belt.
  • that is now generated by the brake roller set and the pull roller set that stretching train which is required for the elastic deformation of the continuous belt.
  • the rollers of the brake roller set and the pulling roller set therefore has a relatively high stretching component.
  • the belt does not experience any permanent transverse changes in the course of its elastic deformation.
  • the plastic deformation of the strip in the course of the stretching process takes place only in the area of the pair of drawing stretching rollers, which has the remaining and comparatively low stretching component.
  • the stretching required for the desired stretching of the belt is thus divided between the brake roller set and the pulling roller set for the elastic stretching on the one hand and the pair of tension stretching rollers for the plastic stretching of the relevant strip on the other hand.
  • the invention is based on the knowledge that only a low stress component is required for the stretching in the plastic region, that is to say in order to reach and, if necessary, to slightly exceed the yield or flow limit of the strip material.
  • the invention also relates to a train stretching system which is particularly suitable for carrying out the claimed method and has a brake roller set and a train roller set in its basic structure.
  • This train terran location is characterized in that a pair of draw rollers is arranged between the brake roller set and the pull roller set.
  • the tensioning of the brake roller set, pair of draw rollers and pull roller set can take place in a known manner.
  • the drawing stretching rolls have metallic roll shells, the surface of which is hardened or hard-coated and finely machined.
  • the friction between the belt in question and the pair of tensioning rollers is minimized in such a way that transverse stresses no longer build up due to frictional influences from the belt edge to the belt center, but rather an essentially uniform tension distribution over the belt width is achieved.
  • the invention provides that the roller shells of the pull rollers made of a metal alloy with a low coefficient of friction such. B. of austenitic cast iron with lamellar or spheroidal graphite, bronze alloys. Like. Consist. This also allows sliding without tendency to seize. The sliding effect can be further optimized in that the tension stretching rollers are preferably coated with a lubricant, e.g. B.
  • the diameter of the drawing stretch rollers is expediently 1,500 times greater than the maximum strip thickness, so that the bend on the drawing stretch rollers which is still involved in the plastic drawing stretch has only a slight influence on the longitudinal curvature or flatness.
  • a tension stretching system for the continuous tension stretching of thin metal strips M made in particular of steel, aluminum or the like is shown with a strip thickness between 0.05 mm and 0.5 mm.
  • this pull stretching system has a brake roller set A with brake rollers 1, 2, 3, 4 and a pull roller set B with pull rollers 7, 8, 9, 10. Between the brake roller set A and the pull roller set B, a pair of draw rollers C with draw rollers 5, 6 is arranged. At least the tension stretching rollers 5, 6 have metallic roller jackets 11, the surface of which is hardened or hard-coated and finely machined. In particular, it can be a metal alloy with a low coefficient of friction such as. B.
  • the draw rollers 5, 6 can be acted upon with a lubricant.
  • the diameter of the draw rollers 5, 6 is 1500 times larger than the maximum strip thickness.
  • the brake roller set A and the pull roller set B can basically have two or more brake or pull rollers. The bracing can be done in a known manner.
  • the transverse expansion is a factor 1 10th reduced because the band in the intermediate stretching roller pair C between the brake roller set A and the tension roller set B is only subjected to the stretching stretch required for its stretching in the plastic region, namely about 5% - 25% of the maximum stretching stretch for the plastic stretching, while with the brake roller set and tension roller set 75% - 95% of the maximum stretch, however, are only generated for the elastic stretching of the belt.
  • FIG. 5 shows a train stretching system which has independent inventive significance.
  • tension-controlled brake drives 12 operate on the brake rollers 1, 2, 3, 4 and tension-controlled tension drives 13 on the tension rollers 7, 8, 9, 10 and a speed-controlled stretching drive 14 on the tension stretching rollers 5, 6, with the interposition of a superposition gear 15
  • a speed-controlled main motor 16 operates as a speed master for the traction roller set B.
  • the brake roller set A and the traction roller set B are traction-controlled, while the traction roller pair C is connected via a differential gear and the stretching drive 14 as the tensioning motor the desired one Degree of stretching generated by speed control.
  • the stretching drive 14 operates, plastic stretching takes place.
  • the stretching drive 14 is set with the percentage of the rotational speed of the main motor 16, so that the stretching drive 14 effects a uniform stretching over the entire speed range.
  • the superposition gear 15 consists essentially of a planetary gear and a bevel gear connecting shaft, via which the draw rollers 5, 6 are supported.
