Definitions

  • the invention relates to a roller straightening machine with a straightening path along which straightening rollers are arranged offset both above and below one another and the rollers located above the straightening path are fastened in an upper roller mill and those below are fixed in a lower roller mill, at least one of which is adjustable.
  • the material to be processed is fed in the form of a strip-like sheet, which the manufacturer mainly supplies in a rolled-up state.
  • the sheet metal strip remains in a strongly bent state for a frequently longer period, the respective curvature of the strip inside the roll being particularly high and decreasing from there to a certain value up to the outer edge.
  • straightening machines are used for this purpose, in which the sheet metal strip is guided along a straightening path between straightening rollers arranged above and below and offset with respect to one another, so that it is aligned, in the majority of cases in the flat state.
  • the degree of curvature of the strip changes at the infeed of the straightening machine in the sense that the curvature increases with the length of the runout.
  • one of the roller mills is usually the upper one, which means that both a shift of the roller mill while maintaining the parallel arrangement of the straightening rollers as tilting of the same, ie a change in the clear cross-section along the straightening path, is also possible.
  • the sheet metal strip is not fed to the processing machine in a flat state but with a certain pre-curvature up or down. This can, for example, make it easier to pull it in and thread it into the tool itself, or it can compensate for any distortions in the workpiece that occur during pressing or punching by means of corresponding counter-tensioning in order to obtain a flat end product.
  • the invention has set itself the task of further developing roller straightening machines with the aid of which sheet metal strips with different and adjustable curvatures can be produced and obtained.
  • This object is achieved according to the invention in that the last direction seen in the transport direction roller in relation to the common inner tangential plane defined by the remaining straightening rollers of the same roller mill is attached to the outside.
  • the straightening rollers of a roller mill are attached in such a way that they span a tangential plane common to all rollers towards the side of the straightening path, which roughly defines the limitation of the straightening path.
  • the main idea of the invention is that, in deviation from this, the last straightening roller is displaced outwards, so that the cross section increases in this area.
  • the staggered arrangement of the straightening rollers of the upper and lower roller frame clearly defines the last, shifted straightening roller.
  • the straightening roller to be moved can be attached to both the upper and lower roller mill.
  • the straightening rollers of the roller straightening machine are not to be attributed to the feed or extraction rollers.
  • the straightening roller located on the opposite roller mill which at the same time represents the last of this chair, but not that of the entire device, is located between the last straightening roller which is offset outwards according to the invention and the straightening roller which is arranged directly in front of it on the same roller mill.
  • This last straightening roller can be moved by moving one of the two roller mills to the two oppositely arranged straightening rollers, one of which is offset, with the result that the strip leaving the straightening machine has a curvature in the direction of the through this straightening roller defined roller mill.
  • the procedure just described for obtaining a certain curvature of the continuous strip can also be carried out in principle in the straightening machines which are already familiar from the state of Tecknik. However, only the exiting band can be curved in one direction in this way. It is crucial that the proposal according to the invention of moving the last straightening roller outwards opens up the possibility for the first time of obtaining a curvature in the opposite direction.
  • the roller straightening machine proposed according to the invention allows, by the known and already existing adjustment of a single roller mill, the curvature of the strip emerging from the machine to be carried out in both directions from the plane defined by the straightening path and to be influenced in its strength.
  • the straightening rollers are connected to intermeshing drive wheels and also support rollers, in particular the last drive wheel and the support roller can also be retained if the displacement of the last straightening roller takes place on a circular arc, the curvature of which is that of the last drive wheel meshing with this straightening roller matches.
  • the last straightening roller is then still connected to the corresponding (last) drive wheel and the support roller.
  • This type of displacement only requires the adjustment of the last straightening roller and leaves all drive wheels and support rollers unchanged.
  • the structural changes to be made to the known devices for realizing the invention are therefore small and simple to carry out.
  • the roller straightening machine shown consists, in a manner known per se, of an upper roller mill 1 and a lower roller 2.
  • the upper roller mill 1 is in this case equipped with four upper straightening rollers 3, 4, and the last of the upper straightening rollers to simplify the description of the function which will be made later provided with the reference number 4.
  • the lower roller mill 2 consists of five lower straightening rollers 5 and 6, the last lower roller here also being provided with reference number 6.
  • four drive wheels 7 are also attached and shown in meshing relationship with the lower straightening rollers 5, 6.
  • a strip 8 preferably made of sheet metal, is unwound from a roll 9 and introduced into the straightening section 10 defined by both the upper straightening rolls 3, 4 and the lower straightening rolls 5, 6. It is crucial that in the Tecknik state all upper straightening rollers 3, 4 in the region of straightening path 10 and the same tangential plane 11 and the lower straightening rollers 5, 6 span the lower tangential plane 12. The result is a flat band 8 free from curvatures.
  • the difference of the invention in contrast, is that the last lower straightening roller 6 is shifted outward in an arc in the direction of arrow 13.
  • the axis of rotation is shifted along an arc, the curvature of which is determined by that of the last drive wheel 7, so that even after the shift, the last lower straightening roller 6 is still in engagement with the associated drive wheel 7.
  • the already shifted straightening roller 6 is shown in solid lines and in its normal position in dashed lines. The displacement of the last lower straightening roller results in a downward curvature of the belt 8 leaving the straightening machine.
  • this curvature in particular the respective dimension, can be carried out by adjusting the last upper straightening roller 4, which is done by translating and tilting the upper roller mill 1 as a whole in parallel position. This gives a movement of the straightening roller 3 in the direction of arrow 14. The lower the position of the straightening roller 4, the more the belt 8 emerging from the straightening machine is given an upward curvature. Due to the already known adjustment of the upper roller mill 1, the curvature of the strip 8 can be influenced in any way when it exits the straightening machine.
  • the curvature of the processed strip 8 can be set as desired and in any desired manner.
