Definitions

  • the present invention relates to a straightening machine for straightening a metal strip or flat metal parts according to the preamble of claim 1 and a method for operating such a straightening machine according to the preamble of claim 12.
  • Such a straightening machine comprises a number of upper straightening rolls, which are mounted in an upper roll frame, and a number of lower straightening rolls, which are mounted in a lower roll frame.
  • the upper and lower straightening rollers are arranged in such a way that they form a straightening gap between an inlet and an outlet of the straightening machine in order to act there from above and from below on the metal strip or metal part to be straightened and to guide the metal strip or metal part through the straightening machine.
  • the straightening rollers are provided with coupling elements for coupling drive shafts, usually articulated shafts of a drive device.
  • the straightening rollers can be removed from the respective roller mill so that they can be replaced after a wear limit has been reached.
  • Straightening machines of the present type are used to eliminate tension and unevenness in metal strips or metal parts.
  • the upper and lower straightening rollers are offset from one another along the straightening gap in such a way that the material to be straightened is guided through the straightening gap in a kind of wavy line and is bent up and down alternately on the straightening rollers.
  • the bending takes place in such a way that the material is bent beyond its yield point, at least on the first straightening rollers, so that undesired bends and stresses in the material are eliminated as completely as possible.
  • the material is usually heavily plasticized on the first straightening roller of the leveler. At each additional straightening roller the material is slightly less bent and the material is no longer plasticized at the last straightening roller, ie it is only elastically deformed.
  • metal strips are often used, which are delivered as so-called coils and unwound from there for production.
  • a leveler of the type mentioned is for example from EP-A-2 712 687 known.
  • This known straightening machine is also particularly suitable for straightening flat metal parts and deals with the problem that the straightening gap of the straightening machine widens during a straightening process when stud bolts are used to connect the upper and lower roller frames.
  • More straighteners of the present type are, for example, from EP-A-2 002 907 , which deals in particular with a gear arrangement for the leveler, and from EP-A-1 491 270 known.
  • the straightening rollers of a straightening machine of the present type usually have a coupling element on one end face for coupling cardan shafts of the drive device. This is usually designed as a coupling pin with an external profile. On the opposite end of the straightening rollers there is a bearing journal for an axial bearing in the respective roller mill. To remove the straightening roller from the roller mill, the cardan shaft on the drive side is pulled off the straightening roller, the associated bearing is loosened and the straightening roller is pulled out of the opposite bearing.
  • the straightening rollers of a straightening machine of the present type are exposed to high forces and are therefore subject to more or less rapid wear.
  • the straightening rollers When the straightening rollers have reached a level of wear that leaves visible defects on the surface of the metal strips or metal parts to be straightened, the straightening rollers must be replaced. Due to the necessary high stability, strength and dimensional accuracy of the straightening rollers, replacing the straightening rollers is correspondingly expensive.
  • the present invention is therefore based on the object of proposing a straightening machine of the type mentioned at the beginning and a method for operating this straightening machine, with which the service life of the straightening rollers is increased, in particular when the straightening machine is also used for straightening flat metal parts can be.
  • straightening rollers of straightening machines which are used for straightening flat metal parts, wear particularly quickly on that side of the straightening machine which is opposite the drive device.
  • This is related to the fact that a person who operates the straightening machine and puts the metal parts to be straightened into the infeed of the straightening machine, usually placing them on a roller conveyor or other conveyor device arranged in front of the infeed, staying on the side of the straightening machine opposite the drive device.
  • the metal parts to be straightened are not usually centered if they are narrower than the width of the infeed, but enter the straightening gap near the operator, i.e. on the side of the straightening machine facing away from the drive device. This means that the leveling rollers on the operating side of the leveler wear out more quickly than on the drive side.
  • the service life of the straightening rollers can be significantly increased simply by turning the straightening rollers inside the straightening machine, i.e. after a number of removed from the respective roller mill after the straightening processes carried out, turned over and reinserted in the roller mill with the end faces swapped over.
  • the straightening rollers that are to be turned are not only provided with coupling elements on one end face, but rather have coupling elements on both end faces. In itself, this is in different contexts from the CN-B-104226735 , On which the preamble of claim 1 is based, of CN-U-203235784 and the CN-U-205217654 known.
  • the coupling elements can be designed as drive pins with a profiled cross section for axial torque transmission by means of a drive shaft or articulated shaft that can be plugged on; alternatively, it can be provided that the coupling elements are in the form of drive sleeves with a profiled cross-section, into which correspondingly profiled pins of drive shafts can be inserted.
  • the straightening rollers designed in this way can be coupled and uncoupled from the drive shafts of a drive device by means of an axial movement.
  • the reversible design of the straightening rollers according to the invention makes it possible to achieve a greatly improved service life of the straightening rollers, with the improvement being greater the more often metal parts are straightened that enter the straightening gap eccentrically, usually shifted to the operator side of the straightening machine.
  • the areas of the straightening roller that are subject to greater stress and are therefore subject to faster wear are exchanged for the areas of the straightening roller that are subject to less stress and are therefore less worn. In the ideal case, this results in an essentially uniform stress on the straightening rollers.
  • the straightening rollers are not only rotated periodically and reinserted into the roller mill with the end faces swapped over, but also the sequence of the straightening rollers along the straightening gap is reversed periodically. Because it has been recognized that the straightening rollers are subjected to greater stress during the straightening process and accordingly wear out more, the closer they are arranged to the inlet of the straightening machine.
  • each straightening roller is assigned at least two pairs of support rollers on its side facing away from the straightening gap, which support the straightening rollers against bending during the straightening process.
  • the support roller pairs for to arrange a straightening roller in such a way that they are not positioned symmetrically with respect to a center of an imaginary line between the two bearing points of the straightening roller. This means that after the straightening roller has been turned, the contact areas between the support rollers and the straightening roller are located at a different point on the straightening roller, so that premature wear in these contact areas and in particular in the area of the front edges of the support rollers is avoided. This also further increases the service life of the straightening rollers.
  • this load is a measure of the load and thus indirectly of the wear and tear to be expected from the corresponding straightening cycle, and it receives a lower value if, for example, the time interval of the force is shorter than in a straightening process with a longer time interval, for example because metal parts are of different lengths have been straightened, which otherwise have the same dimensions and consist of the same material, or it receives a higher value corresponding to a detected asymmetry of the forces.
  • individual values of forces are preferably measured which occur in the straightening machine between the two roller mills at different points Locations within the straightening machine act simultaneously, ie the asymmetric distribution of the forces - if there is one - is preferably detected. This can also be done purely quantitatively by counting when threshold values for a corresponding asymmetry of the forces are exceeded and for a time interval in which this asymmetry is above the threshold values. However, a better approximation of the actual wear-related processes can be achieved if any asymmetrical distribution of the forces and their progress over time is qualitatively recorded and, if necessary, summed up.
  • an expected value for wear of the straightening rollers is determined from the quantitatively and/or qualitatively recorded forces which act during a straightening process between the upper and the lower roller mill, from their course over time and possibly their asymmetric distribution, and after reaching a predetermined expected Threshold value, the straightening rollers are removed from the respective roller mill, turned and reinserted into the roller mill with reversed end faces and possibly also with reversed order along the straightening gap.
  • Threshold value a predetermined expected Threshold value
  • sensors are preferably provided for detecting forces which act between the upper and the lower roller mill during the straightening process. This detection of forces can in turn be done quantitatively and/or qualitatively.
  • the sensors are preferably distributed in the straightening machine so that, in addition to detecting the forces acting between the upper and lower roll frames during the straightening process, they can also quantitatively and/or qualitatively detect an asymmetric distribution of the same.
  • the studs are usually provided with sensors, in particular displacement sensors, which detect an elongation of the respective studs. It is therefore advantageous within the scope of the present invention if the sensors for detecting the forces acting between the roller mills and possibly their asymmetrical distribution are precisely those sensors which detect an elongation of the respective stud bolts and are designed, for example, as displacement sensors.
  • a collective load memory is preferably assigned to the sensors of the straightening machine according to the invention, which quantitatively and/or qualitatively record the forces acting during the straightening process between the upper and lower roll mills, their temporal progression and/or their asymmetrical distribution. This serves to store detected forces and/or to store and add up straightening cycles determined quantitatively or qualitatively from the detected forces.
  • the collective load memory can be designed in such a way that it stores the forces recorded during a straightening process and their progression over time, as well as - insofar as recorded - their asymmetric distribution and/or calculates a load and, if necessary, its asymmetric distribution from this and the calculated value as a saves the load cycle.
  • These load cycles are a measure of the wear-generating load on the straightening rolls, with an asymmetric distribution possibly being weighted into the load cycles, so that summing up the load cycles, which can be done in the collective load memory, enables the wear caused by the load to be estimated.
  • the straightening machine according to the invention is provided with a wear calculator, which is designed in such a way that it calculates a wear value from the straightening cycles or load cycles summed up in the collective load memory and, when a predetermined wear threshold value is reached, outputs a signal to turn the straightening rollers .
  • the wear calculator can be designed in such a way that it calculates an expected value for wear of the straightening rollers based on the forces stored in the collective load memory and detected by the sensors and their progression over time and, if detected, their spatial distribution calculated and outputs a signal when a predetermined expectation threshold value is reached.
  • the intermediate step of adding up the straightening cycles or the load cycles can be omitted in the latter case.
  • FIG 1 a plan view of a straightening machine of the present type is shown.
  • the actual straightening machine 1 in which the straightening rollers (not visible here) are mounted, is provided with a drive device on the drive side shown here on the right, which consists of a drive motor 2 and a gear block 3 as well as a number of cardan shafts 4, which connect the individual gear connections connect with coupling elements 5 of the straightening rollers.
  • An inlet 6 and an outlet 7 of the straightening machine are provided with an inlet roller conveyor 8 and an outlet roller conveyor 9, respectively, in order to feed flat metal parts 10 into the inlet 6 and remove them from the outlet 7 in a directed manner.
  • the straightening machine 1 has a wide inlet 6, there are quite often metal parts 10 during operation, the width of which does not correspond to the width of the inlet 6. These are then, as in figure 1 shown, off-centre, shifted towards the operating side, onto the infeed roller conveyor 8 hung up. Accordingly, when straightening the metal part 10, the straightening rollers of the straightening machine 1 are only loaded in the areas oriented towards the operating side, while those towards the in figure 1 Areas of the straightening rollers that are oriented toward the drive side shown on the right remain completely unstressed by this straightening process.
  • figure 2 shows a schematic side view of the straightening machine 1 figure 1 , seen from the operating side.
  • An upper roller frame 12 and a lower roller frame 14 are mounted in the frame 11, the two roller frames 12, 14 being connected to one another by means of four stud bolts 20.

  • the upper and lower straightening rollers 15, 16 are each arranged in a row one behind the other in such a way that they form a straightening gap 17 between the row of the upper straightening rollers 15 and the row of the lower straightening rollers 16, which gap extends from the inlet 6 to the outlet 7 through the straightening machine 1 extends.
  • a metal part is now placed in the inlet 6, it is transported through the straightening machine 1 in the straightening gap 17 between the upper straightening rollers 15 and the lower straightening rollers 16 and, in the process, alternately around the upper and lower straightening rollers 15, 16 in a serpentine upwards and downwards bent.
  • the straightening rollers 15, 16 are offset at the straightening gap 17.
  • the stud bolts 20, which connect the lower roller frame 14 to the upper roller frame 12, are firmly anchored in the lower roller frame by means of anchors 18, while they are adjustably fastened to the upper roller frame 12.
  • the adjusting devices 13 are in figure 1 to recognize; on the one hand, they are firmly connected to the upper roller frame 12 and, on the other hand, carry a counter bearing for the stud bolts 20.
  • the height of the counter bearing relative to the upper roller frame can be changed by means of the adjusting devices 13, so that the stud bolts 20 can be lengthened during a straightening process in which the Straightening gap 17 is widened by a metal part, by shifting the counter bearing can be compensated upwards by also "elongating" the mounting of the stud bolts 20 on the upper bearing block 12 in a corresponding manner.
  • the adjusting device 13 does not change the actual length of the studs 20, but only their effective length, which is proportional to the straightening gap 17, and can keep the straightening gap 17 constant.
  • the force flow of the opposing forces runs from the upper roller mill 12 via the stud bolts 20 into the lower roller mill 14.
  • the stud bolts 20 lengthen here, with the lengthening being all the more pronounced the less complex the stud bolts 20 are designed . Due to the elongation of the stud bolts 20, the straightening gap 17 widens, but this is compensated for by the adjusting device 13.
  • sensors 19 are attached to all four stud bolts 20, which in the present case are embodied as displacement sensors. Based on the values for an elongation of the studs 20 reported by the sensors 19 to a machine control, the adjusting device 13 can increase the height of the counter bearing of the studs 20 on the upper roller frame 12 accordingly, so that the effective length of the studs 20 does not change despite an elongation of the same and thus the straightening gap 17 remains constant, ie does not widen.
  • This configuration of a leveler is in itself from the EP-A-2 712 687 known.
  • the sensors 19, which are already present as displacement sensors for the adjusting device 13, can also be used to record the forces acting during a straightening process between the upper roller frame 12 and the lower roller frame 14, specifically at all four corners of the Roller mills 12, 14, namely on each stud 20.
  • the wear of the straightening rollers 15, 16 can be inferred from the values supplied by the sensors 19 in different variants.
  • completed straightening cycles can be counted, a straightening cycle being counted when a specific force in straightening gap 17 or, in the present example, a certain path of sensors 19 for the elongation of studs 20 is exceeded for a specific time interval.
  • a number of asymmetric straightening cycles are counted, which are accordingly defined by a specific asymmetry of sensor values being detected above a specific threshold and over a predefined time interval.
  • a signal is output at the controller of the straightening machine 1, which indicates that the straightening rollers 15, 16 are turned and/or in should be reversed in their order along the straightening gap 17 in order to achieve uniform wear of all straightening rollers 15, 16.
  • the extent of asymmetric wear of the straightening rollers 15, 16 can also be inferred from spatially and time-resolved measured values for the forces acting in the straightening gap, and this extent can be used as a trigger for a signal to turn and/or swap the straightening rollers 15, 16 will.
  • the straightening roller 15 In order to be able to turn the straightening rollers 15, 16, they are provided with coupling elements 5 on both end faces according to the invention.
  • FIG 3 which shows the two end faces of a straightening roller 15 according to the prior art, this is made clear:
  • the straightening roller 15 only has one of its end faces via a coupling element 5, which is designed here as a drive pin with a profiled cross-section for axial torque transmission.
  • the straightening roller 15 has a bearing journal 21 on the other end face.
  • the straightening roller 15 according to the prior art is mounted in a conventional axial bearing 22 in the associated roller frame 12 by means of this bearing journal 21 .

  • the straightening rollers 16 are supported against the straightening pressure in the roller mill 14 by means of the support rollers 23a, 23b, so that on the one hand the entire straightening pressure is not removed via the first bearing points 24 and the second bearing points 24 and on the other hand a deflection of the straightening rollers 16 is avoided.
  • support roller pairs 23a, 23b are not positioned symmetrically with respect to a center of an imaginary line connecting the two bearing points 24, 25 of the straightening rollers 16, but are preferably each shifted a little to the left.
  • the track of the pairs of support rollers 23a, 23b is then in a different area of the straightening rollers 16 or is slightly offset, so that here too the wear caused by the contact between the support rollers 23 and the straightening rollers 16 is evened out he follows.
