Definitions

  • the invention relates to a method and a machine device for straightening of profiles with the help of one or more above and below the target mutually parallel straightening axes arranged in series straightening tools for Elimination of multi-axis deviations from the required profile.
  • Profiles are placed on a cooling bed after rolling. Here they remain for cooling generally up to a temperature of approx. 60 ° C. Through the rolling process, like but especially due to the cooling especially warp unbalanced the profiles vertically as well as horizontally and can additionally still twist about its longitudinal axis. The consequences are besides the geometrical Non-uniformity of the rolling stock Internal stresses in the material Show the division of the profile even more clearly.
  • a device for re-bending thin-walled profiles into their desired shape is known from DE-AS 1264936, different form rollers being used depending on the type of profile.
  • a molding tool is also known that has a disk-like tool that extends into the profile.
  • the drive unit receiving the tool is tiltably mounted. Straightening thick-walled profiles created by rolling is not possible with this device.
  • the object of the present invention is a method and a machine Device to create low-stress straightening of profiles with the or an improved directivity by taking into account Directional axis deflection is achieved due to changing straightening forces.
  • both the straightening force adjustment and the adjustment of the horizontal inclination of the adjustable straightening axis take place hydraulically, wherein the hydraulic system is designed so that a quick change of position on the front and rear hydraulic cylinders as well as exclusively on the rear hydraulic cylinder is possible such that the straightening force and / or the horizontal inclination of the adjustable straightening axis can also be adjusted during straightening.
  • the straightening method according to the invention enables very quick compensation the bending of the straightening axes during the straightening process and thus allows the Correction of the straightening gap with changing straightening forces.
  • each directional axis with the Straightening tools independent of the other straightening axis without load in the axial direction adjustable is carried out electro-mechanically, and then one hydraulic bracing is carried out, so that a play-free axial position is achieved.
  • each Adjusting device has a measuring system, the signal in a computer-based rule model is fed in, taking into account the Geometry of the straightening machine and the measurement results, the straightening roller position, as well the straightening roll angle is calculated with the straightening of the straightening axis and specifications for optimizing the straightening gap are determined with which the Straightening axes can be set.
  • the advantage of the method according to the invention is that the straightening gap can also be readjusted under straightening force by adjusting the systems. In this way, fluctuations in directivity can be dynamically compensated for by the odd or non-uniform shape of the profile.
  • the hydraulic adjustment also allows the overload protection to be implemented simply because only one pressure relief valve has to be integrated into the hydraulic system.
  • a mechanical device for straightening profiles is characterized in that that at least one, preferably the lower leveling unit, over the two Vertical-acting hydraulic cylinders articulated at the ends of the directional axis is adjustable.
  • the hydraulic cylinder facing the straightening unit as Straightening cylinder is primarily provided for setting the straightening gap and the Hydraulic cylinder facing away from the straightening unit as an inclination cylinder.
  • the straightening cylinder, the tilt cylinder and the horizontal actuators, displacement transducers and on the straightening cylinder Force measuring devices are provided, the measured values of which together with the measured current consumption at measured values representing the main drives can be fed to a computer in which the Setting values for the degrees of freedom of the mechanical device can be calculated.
  • controlled adjustment and readjustment of the axis inclination can be carried out to compensate for the bend around a parallel straightening gap so that with the straightening method according to the invention and the machine device one independently of each other play-free determination of the axial position of the upper and the lower directional axis is possible, as is a horizontal as well as a vertical one Straightening and calibrating ability.
  • the setting and readjustment of the invention Axis inclination creates a parallel straightening gap even under rolling load.
  • the straightener essentially consists of one, but not in its details Upper and lower straightening roller unit 4, shown in more detail.
  • the upper Straightening roller unit each contains a drive including gear 1 which with the upper straightening axis 2 is connected, on which one or more straightening disks 3 e.g. different diameters above the profile, not shown, on one Sleeve to the straightening roller unit 4 are arranged pre-assembled.
  • Each lower straightening roller unit 4 is adjustable in height. Via a hydraulic cylinder 5.6 the directional axis 12 is brought into position. During the straightening roller unit 4 facing straightening cylinder 5 primarily sets the straightening gap, is on the free Inclination cylinder 6 located at the end of the directional axis is the one that sets itself under load Correction of the directional axis compensated. For this purpose, the lower directional axis 12 is above the Straightening cylinder 5 articulated in a spherical cap 10.
  • the lower directional axis 12 is guided in a carriage 11 in the base frame of the Machine is attached.
  • the lower 12 as well as the upper 2 directional axis are in rolling bearings stored and are axially adjusted by a gear motor 13.
  • the approached Position is clamped without play using a hydraulic clamping mechanism.
  • For Targeted adjustments are made at the end of the axis Control are involved.
  • Via the measuring device for the horizontal Adjustment of the straightening roller set 4 are also the prerequisites for precise Positioning given. This degree of freedom comes especially from judging and Calibrate asymmetrical profiles.
  • the computer model belonging to the regulation and setting of the machine relates to the set-up profile-related values that come from a database.
  • the Straightening cylinder 5 also has a straightening force measurement 7.
  • the tilt cylinder 6 at the free end of the directional axis also has a like the end of the directional axis Position measuring system 9. All position measuring systems have the task of their actual value for the To provide control, and also serve to specifically change the position to start.
  • the displacement measuring device is not arranged on the base of the vertical adjustment - that is, below the directional axis - but on the city side opposite the directional axis.
  • the displacement measuring device can be a linear encoder 14, to which a magnet belongs, which - as before - is attached to the adjustable axis. This configuration ensures that the spring deflection of the chocks and the stand itself is also measured, so that only the roll deflection has to be taken into account as an additional compensation value.
