Definitions

  • the invention relates to an arrangement for grinding a metal strip, comprising a grinding device, a pressure device acting on the grinding device with at least one Anyakmotor for moving / pressing the grinder against said metal strip, a measuring device for measuring the thickness / surface of the metal strip, which in the direction of movement the metal strip / grinding device is arranged in front of the grinding device, and a drive for moving the metal strip relative to the grinding device and / or vice versa. Furthermore, the invention relates to a method for grinding a metal strip, in which a thickness / surface of the metal strip is measured prior to grinding, a grinding device is moved / pressed against the said metal strip and / or vice versa and in which the metal strip in the longitudinal direction relative to Grinding device is moved and / or vice versa.
  • the AT 505 640 A1 to a method in which the metal strip is ground by a grinder and then its thickness is measured by means of a measuring device. If the result obtained is not satisfactory, the metal strip is ground again and then measured again in terms of its thickness. This process is repeated until the metal strip has the desired thickness. For example, such a processing operation in the production of (high-gloss polished) endless belts made of stainless steel.
  • a disadvantage of this arrangement, or in this method is that the grinding device in the known method in places where no removal must take place, under certain circumstances lifted off the metal strip and grinding a dent during reassembly. This naturally precludes the desired homogenization of the thickness of the metal strip.
  • An object of the invention is therefore to provide an improved arrangement and an improved method for grinding a metal strip.
  • the metal band After grinding it should be free of any unevenness, and the grinding process should be faster.
  • the metal strip has a substantially uniform height / roughness profile after the grinding process, or the grinding process can also be carried out in a shorter time, since due to the proposed measures usually less grinding passes are a satisfactory result than in conventional methods.
  • the metal strip of Antikmotor is controlled by the control / regulation based on the determined actual height / roughness profile. Specifically, the contact pressure is increased at those points of the metal strip, which have a high height, or roughness. Accordingly, the contact pressure is reduced at those points of the metal strip, which are relatively low in relation to a desired plane, or have a low roughness.
  • the pressure of the grinding device against the metal strip is not lowered below a predefinable (positive) minimum value during the grinding process.
  • the measuring device comprises at least one ultrasonic sensor. In this way, the thickness / surface of the metal strip can be measured quickly and accurately.
  • the pressure device comprises at least one group, each with two pressure motors coupled in series and different in terms of their drive type.
  • a first Anyakmotor for the coarse adjustment a second Anyakmotor be provided against the fine adjustment.
  • At least one An horrmotor is designed as a hydraulic cylinder.
  • a hydraulic cylinder can generate relatively high forces; on the other hand, it is also possible to realize relatively large displacement paths.
  • At least one pressure motor is designed as a piezoelectric sensor. In this way, the pressure device and thus the grinding device can be adjusted very quickly.
  • the pressure device and / or the grinding device comprises at least one mass which can be deflected by a motor.
  • the grinding device has a plurality of independently controllable pressure devices which act on portions of the metal strip, which are spaced apart in a widthwise extension of the metal strip is particularly advantageous.
  • the grinding device or its pressure device is segmented.
  • the abrasive medium e.g., abrasive belt, abrasive roll
  • abrasive belt, abrasive roll can be pressed against the metal strip in the individual segments in this way to different extents.
  • a comparatively wide path can be ground on the metal strip in one pass, without having to forego an individually adjustable ablation.
  • the presented arrangement comprises a spraying device acting on the grinding medium of the grinding device and / or the metal strip. In this way, the grinding device and the metal strip can be cleaned of dirt or cooled.
  • the grinding medium is designed as a grinding belt and the spray is arranged in the region of a drive roller for the grinding belt and / or a deflection roller for the grinding belt.
  • the spraying device is oriented at an angle which deviates from the normal to the drive roller / deflection roller on which the spraying device acts. In this way, dirt from the sanding belt can be removed particularly well, since the centrifugal forces acting in the area of the drive / deflection roller have a supporting effect on the cleaning.
  • the spraying device acts on a region of the metal strip which is arranged in the direction of movement of the metal strip immediately in front of the grinding device is. In this way, the metal strip is again cleaned / cooled immediately before grinding.
  • a wiper lip may be provided.
  • control / regulation is set up to detect a vibration of the pressure device and / or grinding device and to drive at least one pressure motor and / or the at least one motor-deflectable mass substantially in the opposite phase to the detected vibration. Due to hardly avoidable vibrations in the grinding device, despite a triggering of the pressure motor in the above-mentioned manner, a ripple in the height profile may result in the end result. In order to further improve the grinding result, it may now be provided to detect a vibration of the pressure device and / or grinding device and to actuate the pressure motor and / or the at least one motor-deflectable mass substantially in antiphase to the detected vibration, so that the height profile achieved is largely straight ,
  • a cutting speed during grinding is selected on the basis of the determined thickness / surface. Specifically, the cutting speed can be increased with high desired removal over the cutting speed with low desired removal and vice versa.
  • the cutting speed is generally determined by the relative speed between metal strip and abrasive medium.
  • a speed of the metal strip during grinding is selected on the basis of the determined thickness / surface. Specifically, the belt speed at high desired removal compared to the belt speed can be lowered with low desired removal and vice versa. In general, the belt speed determines the residence time of the metal strip on the grinding device.
  • the inertia of the pressing device is taken into account.
  • a change in movement / pressure is already initiated before this would be indicated on the basis of the determined actual height / thickness / roughness profile. This means that, for example, an increase in the pressure is increased / decreased already somewhat before the appearance of a mountain / valley in order to compensate for delays in the control and also the inertia of the pressure device, so that the selected pressure is already present when the mountain / valley arrives at the grinding device.
  • abrasive media eg abrasive media with different grain sizes and / or different abrasive materials
  • the removal rate per period of use / grinding work, the necessary contact pressure for a specific removal rate depending on the period of use / grinding work and / or the required cutting speed for a specific removal rate depending on the duration / grinding work can be determined empirically and stored in said database.
  • the data can also be stored using approximate formulas.
  • the grinding work corresponds to the temporal integral of the grinding performance or removal rate and is measured, for example, in MJ.
  • the measurement of the thickness / surface of the metal strip takes place at another, in particular at a lower, belt speed than the grinding thereof.
  • the measured value acquisition does not need to be adapted to the grinding process.
  • higher measuring accuracies can also be achieved at a slower belt speed.
  • Fig. 1 shows an arrangement 101 for grinding a metal strip 2, comprising a grinding device 3, a pressing device 4 acting on the grinding device 3 with at least one pressure motor 5 for moving / pressing the grinding device 3 against the called metal strip 2, a measuring device 6 for measuring the thickness / surface of the metal strip 2 and a drive 7 for moving the metal strip 2 relative to the grinding device.
  • a grinding device 3 comprising a grinding device 3, a pressing device 4 acting on the grinding device 3 with at least one pressure motor 5 for moving / pressing the grinding device 3 against the called metal strip 2, a measuring device 6 for measuring the thickness / surface of the metal strip 2 and a drive 7 for moving the metal strip 2 relative to the grinding device.
  • the grinding device 3 additionally or alternatively to the drive 7 relative to the metal strip 2 along (in the Fig. 1 horizontally) is displaceable.
  • the metal strip 2 additionally or alternatively to the pressure motor 5 with respect to the grinding device 3 transversely (in the Fig. 1 vertically) is displaceable.
  • the grinding device 3 in this example comprises a carrier 8, in which three rollers 9, 10 and 11 are rotatably mounted. To these rollers 9, 10 and 11, one or more of which are designed as a drive roller (s), a grinding belt 12 is guided. On the support 8, one end of a hydraulic cylinder 5 is fixed, which acts as a pressure motor in this example. The other end is supported on a fixed bearing 13. The metal strip 2 is guided around the drive roller 7 and around the deflection roller 14. Furthermore, the arrangement 101 comprises a control / regulation 15, to which the input side, the measuring device 6 is connected, which is formed for example as an ultrasonic sensor. On the output side, the control / regulation 15 is connected to the hydraulic cylinder 5.
  • the pressure motor 5 is now controlled via the control / regulation 15 on the basis of the determined actual height / thickness / roughness profile. Specifically, the grinding should be done according to the thin line (target removal). For this purpose, the contact pressure is increased at those points of the metal strip 2, which have a large thickness / height or roughness. At the mountain peaks thus the contact pressure is particularly increased.
  • Fig. 3 now shows a result according to the prior art, in which the grinding device 3 is lifted in the valleys A, since there no ablation must take place. However, it can also be seen in the resulting height / thickness / roughness profile that at the end of the valleys A, a dent B is formed by the replacement of the grinding device 3. In part, these are even deeper than the adjacent valley A, which runs counter to the actual purpose of the grinding process, namely the homogenization of the thickness of the metal strip 2.
  • Fig. 4 shows a grinding result in which the pressure of the grinding device 3 against the metal strip 2 is not lowered below a minimum value even when a grinding due to the determined height h / thickness / surface respectively due to the selected target removal would not be necessary per se. This means that even in the valleys A there is an abrasion removal, albeit less.
  • the in a method after Fig. 3 occurring dents avoided.
  • the surface in the valleys A is also leveled, which facilitates grinding in a subsequent grinding pass.
  • the removal rate per period of use / grinding work, the necessary contact pressure for a specific removal rate depending on the period of use / grinding work and / or the required cutting speed for a specific removal rate depending on the duration / grinding work can be determined empirically and stored in said database.
  • the data can also be stored using approximate formulas.
  • a request for the change of the abrasive belt 12 is issued if its duration of use / its completed grinding work exceeds a predefinable threshold. In this way it is avoided that it is ground with an already used abrasive belt 12 in order to avoid overheating of the metal strip 2 and / or other (irreparable) damage to the metal strip 2.
  • the measurement of the thickness / surface of the metal strip 2 is generally carried out before the same.
  • the measuring device 6 is arranged in front of the grinding device 3 in the direction of movement of the metal strip 2 / the grinding device 3.
  • the measuring device 6 can be provided during the measurement of the metal strip 2 a complete run of the same without this being ground.
  • a "map" of the metal strip 2 are stored in a memory, which is used as a result of the control / regulation 15 to control the An horrmotor 5.
  • the measurement of the thickness / surface area of the metal strip 2 is at a different (in particular at a lower) belt speed than the grinding thereof. As a result, the measured value acquisition does not need to be adapted to the grinding process.
  • the metal strip 2 is measured simultaneously to the grinding process.
  • the metal strip 2 is measured / ground in several passes.
  • the grinding process can be controlled or regulated.
  • the drive roller 7 may be provided with a rotary encoder. It is also conceivable that the metal strip 2 itself is provided with one or more position marks that can be optically detected, for example. It is advantageous if the inertia of the pressing device 4 is taken into account for the movement / pressing of the grinding device 3. For example, a change in movement / pressure is already initiated before this would be indicated on the basis of the determined actual height / thickness / roughness profile. This means that, for example, an increase in the contact pressure is increased somewhat before the appearance of a mountain in order to compensate for delays in the activation and also the inertia of the pressing device 4, so that the selected pressure is already present when the mountain arrives at the grinding device 3.
  • Fig. 5 shows an example with so-called "chatter marks" in the strip surface. These are undulating structures that typically have a depth of 1 ⁇ and a length of about 7mm. Basically, the chatter marks are undesirable.
  • the measuring device 6, as in the Fig. 1 represented, offset from the grinding device 3, so that said vibrations can not or only to a limited extent on the measuring device 6 and on the measuring device 6 opposite portion of the metal strip 2 can be transmitted.
  • the measurement of the thickness / surface of the metal strip 2 can therefore be done comparatively accurately.
  • the pressure device 4 can comprise at least one group, each with two pressure motors coupled in series and different in terms of their drive type.
  • Fig. 6 shows an arrangement 102, which of the arrangement 101 from Fig. 1 is very similar.
  • a hydraulic cylinder 5 is arranged in series with a piezoelectric sensor 16. With the help of the piezoelectric encoder 16, it is now possible to compensate for high-frequency vibrations. The contact pressure / the pressure movement of the hydraulic cylinder 5 is superimposed on the contact pressure / the pressure movement of the piezoelectric sensor 16.
  • a second pressure motor 16 it is also possible to provide at least one motor-deflectable mass 17 on the pressure device 4 and / or the grinding device 3.
  • Fig. 7 shows a device 103, which in turn of the device 101 of the Fig. 1 is very similar. In this case, however, a vertically movable mass 17, which, for example, can be deflected electromagnetically, is located on the carrier 8 is.
  • a mass-spring system is adapted to the frequency of the vibration to be compensated, that is, the natural frequency of the mass-spring system largely corresponds to the frequency of the vibration to be compensated.
  • Fig. 8 now shows an embodiment of an assembly 104, which in the Fig. 1 shown arrangement 101 is very similar. In contrast, however, a support roller 18 for the metal strip 2 is arranged in the region of the grinding device 3. As a result, an excessive yielding of the metal strip 2 during pressing of the grinding device 3 is avoided.
  • Fig. 9 shows a further embodiment of an arrangement 105, which in the Fig. 1 shown arrangement 101 is very similar.
  • the grinding device 3 is not arranged in a straight portion of the metal strip 2, but in the region of the deflection roller 14.
  • the measuring device 6 is arranged in the region of the deflection roller 14. Due to the relatively high tensile forces with which the metal strip 2 is stretched, this is very tight on the guide roller 14, whereby the grinding process and the measuring can be done very accurately.

  • the grinding device 3 and the measuring device 6 can also be arranged in the region of the drive roller 7. It is also conceivable that the grinding device 3 is arranged on the deflection roller 14 and the measuring device 6 on the drive roller 7 or vice versa.
  • Fig. 10 shows still another embodiment of an arrangement 106, which in the Fig. 1 shown arrangement 101 is very similar. In contrast, however, this has a force acting on the abrasive belt 12 of the grinding device 3 and the metal strip 2 first and second spray 19 and 20. In this way, the abrasive belt 12 and the metal strip 2 can be cleaned or cooled by means of a grinding emulsion. Concretely, a wet grinding process is realized in this way.
  • the first spraying device 19 is arranged in the region of the guide roller 11. Due to the centrifugal force acting excess abrasive emulsion and dirt are ejected particularly well from the sanding belt 12. Completely equivalent, the first spraying device 19 could also be arranged on the deflection roller 10 for this purpose.
  • the first spraying device 19 as in the Fig. 10 is shown aligned at an angle which deviates from the normal to the guide roller 11, on which the first spray device 19 acts. That is, the first spraying device 19 is aligned flat on the guided around the guide roller 11 grinding belt 12. In this way, excess abrasive emulsion and dirt are even better thrown off the abrasive belt 12
  • the second spraying device 20 acts on a portion of the metal strip 2, which is arranged in the direction of movement of the metal strip 2 immediately in front of the grinding device 3. In this way, the metal strip 2 is again cleaned / cooled immediately before grinding.

  • FIG. 10 also shows that the metal strip 2 and the grinding belt 12 are moved during grinding in synchronism. In this way, dirt can also be kept away from the processing site. In principle, of course, a grinding in the opposite direction is conceivable.
