Definitions

  • the invention relates to a straightening machine for straightening metal sheets and bands, with top and lower straightening rollers, which in turn use their length supported support rollers arranged in roller mills are supported.
  • a straightening machine of this type is described in DE 42 00 922 A1 known.
  • the upper and lower support rollers supporting crossbeam is the upper crossbeam for Positioning the straightening rollers against the lower crossbar adjustable.
  • the straightening rollers of this Straighteners can also be adjusted individually and individually driven, for which they are driven by cardan shafts with a drive are connected.
  • Lowering or Individual straightening rollers are lifted in the lower or upper Roller mill bearing carrier wedges and - for example by a Pressure cylinder - assigned sliding wedges.
  • straightening machines with individually driven straightening rollers are problematic when high-strength and also thin sheets or strips, for example with a yield strength of 1700 N / mm 2, which is common with spring steel, and with a thickness of approximately 2 mm, have to be straightened .
  • the straightening rollers must have a much smaller diameter, for example 45 mm, compared to conventional systems, but the high torques required must nevertheless be introduced. Because of the lower straightening force on the straightening rolls in the case of thinner sheets, the transport guaranteed by the frictional contact between the straightening rolls and the strip or sheet causes difficulties.
  • the invention has for its object a straightening machine to create the kind mentioned at the beginning, with which the Straighten high-strength, thin sheets and strips resulting Have difficulties eliminated.
  • the intermediate rolls on the Supported support rollers are assigned to roller mills.
  • the Intermediate rolls are thus between the the indirect supporting straightening rollers supporting support rollers and the the upper and lower roller mills of the straightening machine supported support rollers, so that the outside from the inside the following structure results: support rollers, driven intermediate rolls, Support rollers, straightening rollers.
  • An advantageous embodiment of the invention sees between the straightening rollers arranged, a smaller diameter than the auxiliary rollers having the straightening rollers. This each in the gaps between two neighboring upper and lower ones Straightening rollers extending, idling, i.e. without contact to the straightening sheet or strip arranged auxiliary rollers support the threading or guiding of the sheet to be straightened or band. Straightening of strips or of continuous Tape material is omitted when the material has been previously hardened. Because hardened, endless Tape material could no longer be adjusted, so that in this Cases, therefore, strip or sheet boards are directed.
  • Straightening roller sets arranged offset to each other can be opposite usual roller systems, in which the upper straightening rollers each in the middle of the distance between two neighboring lower ones Straightening rollers arranged in the form of an isosceles triangle are the straightening rollers with a smaller distance and thus smaller pitch of each in the running direction Set successive upper and lower straightening rollers.
  • the very small divisions or levers between successive, engaged upper and lower Straightening rollers lead to significantly higher straightening forces on the individual straightening rollers, which is one for the transport of the Reach sheet metal with increased frictional contact leaves.
  • a straightening machine 1 has one of two im Foundation anchored stands 2 existing machine frames on.
  • the stands are through an upper frame cross member 3 as well rigidly connected to each other by a lower crossbar 4.
  • On the upper, adjustable crossbar 5 is an upper Roll mill 6 held.
  • a lower roller mill 7 is on the lower crossbar 4 arranged; over on both sides of the Straightener 1 provided in the direction of the straightening good Last, the lower roller mill 7 is based on the Crossbeam 4.
  • the upper crossbeam 5 is over a Adjusting cylinder 8 adjustable against the lower crossbar 4.
  • Roller setting wedges 9 are mounted on the lower roller mill 7 and by a pressure medium cylinder, not shown slidable. Each lower straightening roller 11 this supporting inner support rollers 12, the associated driven, a much larger diameter than that Straightening roller 11 having lower intermediate roller 13 and the this is supporting outer support rollers 14 (see FIG. 2) such a wedge 9 assigned.
  • the one above the level 15 arranged upper roller and roller set 16 is the same Set up like the lower roller and Roll set 17, i.e. the upper straightening rollers 18 are from the inside Support rollers 19 supported, which outward or upward connect driven upper intermediate rollers 20, which in turn are supported by outer support rollers 21.
  • the support rollers 21 of the upper roller and roller set 16 are on one Setting wedge 22 mounted. Each of the neighboring ones, in one of the Number of straightening rolls 18 or intermediate rolls 20 available Number of wedges 22 is on the other side of the upper roller mill 6.
  • the wedges 22 are also through one - not shown - pressure cylinder slidable.
  • the two cross members 4,5 are on the inlet and outlet side Outer, not shown, arranged symmetrically to the machine center Fixed stops against the roller mill 6 or 7 supported. There are also on the inlet and outlet side of the Roller leveler 1 between the lower crossbar 4 and the roller mill 7 assigned to it or the upper crossbar 5 and the associated roller mill 6 with the same distance from each other in a row between the fixed stops arranged compensation cylinders 24 and 25 (see FIG. 1).
  • FIG. 3 are compared to the Straightening rolls 11 and 18 with a much larger diameter executed intermediate rollers 13 and 20 individually driven and for this purpose with coupled drive shafts 26 not shown drives connected.
  • the individually driven Intermediate rollers 13 and 20 are provided with recesses 27, about which to seal the bearings with roller axes in Web plates 28 stored inner support rollers 12 and 19, respectively Medium (sealing air) can be supplied.
  • the in Running direction according to arrow 29 successive lower and upper Straightening roller 11 or 18 with a very small pitch 30 closely moved together; compared to straighteners Conventional straightening roller arrangement can be offset by moving the lower roller and roller set 17th reach receiving roller mill 7.
  • the narrow division 30 allows the straightening forces on the straightening rollers 11 and 18 to increase considerably and thus to transport the sheet or tape in the direction 29 required frictional contact guarantee.
