Definitions

  • the present invention relates to an apparatus and method for removing burnt burrs on wear bodies for guiding metal belts.
  • metal strips In the production of metal strips, these are conveyed by means of metal belt conveyors, for example roller conveyors, to processing machines, for example reels, where they are wound up. It is necessary to subject the metal bands of a lateral guide. Especially before the start of winding this is necessary in order to keep the offset of the individual windings on the wound coil as low as possible in order to achieve a uniform side surfaces.
  • Devices for lateral guidance are called, for example, guide rulers or run-in rulers. The edges of the running metal strip, on which the devices for lateral guidance act, causing a great wear on the - on the guide rulers or inlet rulers attached - wear strips or their wear surfaces.
  • the band edges which are guided with high lateral forces, cut into these wear strips, especially with thinner bands under sparks flying over the entire length of the band - which can be over 2000 m long.
  • the wear surfaces of the wear strips must therefore be renewed several times a week, depending on the production program.
  • Such a device for the lateral guidance of a metal belt running via a metal belt conveyor comprises at least one main body module with guide plane and at least one wear body with a wear surface, which is characterized in that at least one wear body is rotatable about a, preferably substantially perpendicular to the guide plane, rotation axis.
  • all wear bodies of such a device are designed in this way.
  • the metal belt conveyor is, for example, a roller table, for example, a roller table of a tape coiler;
  • the metal strip is for example a steel strip or an aluminum strip.
  • the main body module with guide level is, for example, a so-called guide ruler or inlet ruler, which has a suitable surface for guiding the metal strip, the guide plane .
  • It can for example be formed by one or more - on a support body attached wear plate (s); Support body and wear plate (s) together then form the main body module.
  • the lateral guidance device may comprise a base body module or a plurality of base body modules. For example, two main body modules, for guiding on one side of the metal strip one each.
  • the guide level is used for lateral guidance of the metal strip by means of contact with the sides of the metal strip. It limits the freedom of movement of the metal strip in their direction, whereby the metal strip is guided laterally.
  • the device for lateral guidance also additionally comprises at least one wear body with a wear surface.
  • the wear body is a different component than the main body module, but can be inserted into the main body module or attached to it.
  • the wear body has at least one wear surface, which faces the metal band when the metal band is guided and wears out as a result of contact with the metal band in the course of the lateral guidance of the metal band.
  • the incoming metal strip is pressed with a force of up to 400 kN on the wear body and cuts or eats if necessary under sparks flying into the wear body - for example, in a steel hot strip, which with a temperature of about 600 ° C. and a speed of about 60 km / h - which is basically a desired effect, because the incised contours reinforce the Guiding effect for the metal band.
  • the material of the wear body can be selected with regard to its hardness so that on the one hand the cutting of the guide improving contours promoted, and on the other hand, the replacement intervals are kept to an acceptable extent.
  • the wear body can also have from the outset guide contours for guiding the metal strip, which are still deepened by the cutting of the metal strip during operation.
  • burnt burrs occur due to the seizure of the band and the associated melting of the wear bodies, usually between each roller division of the roller table at the ends of the cut guide surfaces lying in the direction of strip travel. These burnt burrs tend to break off uncontrollably. Firing ridges, which come to rest on the surface of the incoming belt, are rolled into the belt by the driving rollers pressing against the belt with high forces. This causes surface defects on the belt and on the drive roller.
  • Device for the lateral guidance of a running over a metal belt conveyor metal strip comprises at least one main body module with management level and at least one wear body with Schlmony Structure, in which at least one Schllustration stresses about a, preferably substantially perpendicular, to the guide plane standing axis of rotation, is rotatable.
  • a device for laterally guiding a metal strip running over a metal belt conveyor comprising at least one main body module with guide plane and at least one wear body (12) with wear surface, wherein at least one wear body is at an angle between 60 ° and 90 °, preferably substantially perpendicular, to the management level standing axis of rotation is rotatable characterized in that it includes at least one device for removing burrs on the wear bodies.
  • At least one device for removing burnt burrs is fixed in place, wherein the wear body is rotatable relative to this device for removing burrs.
  • the burr can be removed by the burr removing device from this wear body.
  • At least one removal device is movably mounted in the direction of a wear body. In this case, by moving the device for removing burrs, the burr can be removed from this wear body.
  • the firing ridge is sheared off.
  • a further subject of the application is a method for operating a device according to the invention, characterized in that firing burrs on the wear bodies are removed by the device for removing burrs.
  • the burr is removed by the device for removing burrs from the wear body.
  • the burr is removed by the device for removing burrs from the wear body. For example, if it is a shearing device, the firing ridge is sheared off.
  • the device according to the invention and the method make it possible to control burnt burrs and if necessary to remove them automatically.
  • they are removed between guiding two consecutive bands.
  • FIG. 1 schematically shows a conventional device 1 for the lateral guidance of a running over a roller table metal strip 2 laterally from above.
  • the metal strip 2 runs in the direction of the arrow towards the driver 3 a coiler. It is guided laterally by means of the inlet rulers 4a, 4b.
  • FIG. 2 shows a part of a wear strip 5 of an infeed ruler 4a or 4b of a known device 1 for the lateral guidance of a running over a roller table metal strip FIG. 1 , By means of the guide level 6, a metal strip is guided. The wear strip is worn and needs to be replaced. (Dashed line) outlines areas where burnt burrs mostly occur.
  • FIG. 3 shows a section of a device according to the invention for the lateral guidance of a metal belt running over a roller table. Strichliert) surrounds areas where burrs mostly occur.
  • the wear body 12 is a round disc whose base surface forms the wear surface of the wear body. He is about a rotation axis perpendicular to the management level rotatable, which is not shown separately.
  • the axis of rotation is at the center of the round disc.
  • the axis of rotation is arranged above the middle between the axes of rotation of the roller table rollers, which is not shown separately.
  • the wear body 12 is arranged in a largely round recess of the wear plate 9 - since the wear plate 9 does not completely surround the wear body 12, the recess is not quite round; however, the part comprising the wear body 12 is part of a circle.
  • FIG. 4 shows enlarged how a wear body 4 a track 13 is ground, with a burr 14 at the end of the track 13th
  • a device for removing burrs on the wear bodies in this case a shearing device 15 for shearing off the burr 14 from the wear body 4, is also present.
  • Their shearing body 16 is fixed locally, wherein the wear body is rotatable relative to at least one shearing body.
  • the firing burr 14 can be sheared off from the wear body 4 by the shear body 16; represented by a corrugated arrow for the rotational movement of the wear body.
  • FIG. 5 shows one too FIG. 4 largely analogous view.
  • the shearing body 16 of the shearing device 15 is movably mounted in the direction of the wear body 4.
  • the firing burr 14 can be sheared off from the wear body 4 by movement of the shear body 16; represented by a transparent arrow and dashed outlines of the shear body on his way towards Brenngrat.
