Definitions

  • the invention relates to a method for producing metal sheets, in particular large-sized metal sheets, from rolled steel or metal strips with a predetermined strip thickness.
  • metal sheets and in particular large-format metal sheets with sheet formats of z. B. 2 mx 6 m and thicknesses from 3 mm to 15 mm use.
  • the internal stresses which arise from the different cooling after hot rolling must be largely eliminated by means of heat treatment. After this heat treatment - annealing and cooling - the metal sheets are no longer flat. Because of the high demands placed on flatness, such metal sheets are treated discontinuously in stationary roller straightening machines and draw stretchers. The mechanical and, in particular, machining of such metal sheets often gives rise to warpage, dents or the like, which cannot be eliminated satisfactorily by local communication.
  • the invention is based on the object of specifying a method for producing metal sheets and in particular large-sized metal sheets of the embodiment described at the outset, according to which rational and economical sheet production is ensured.
  • the invention in a generic method in that the steel or metal strip in question is first heat-treated by means of a continuous treatment to reduce stresses, is stretch-bend-oriented after the heat treatment and is stretched and stretched by a predetermined amount after the stretch-bending straightening by means of a discontinuous treatment the stretching is cut into predetermined sheet formats.
  • the hot or cold rolled strips can consist not only of steel, but also of such metals as aluminum, copper, brass, titanium or the like.
  • the steel or metal strips can have a length of 100 m to approximately 1200 m and are wound into coils.
  • the steel or metal strip can be straightened before the heat treatment to remove coil sets will. This also applies preferably to thick steel or metal strips.
  • the steel or metal strip is preferably pre-trimmed after straightening and before the heat treatment and after the stretching and before the cutting is trimmed in sheet metal, ie brought to the desired final width by means of trimming scissors.
  • the steel or metal strip is stretched with a degree of stretching of 0.5% to 3.0% in order to completely remove the residual stresses.
  • the invention provides that the steel or metal strip is stretched with overlapping clamping points and the clamping points as well as constriction points are cut out in the course of the final trimming to form the specified sheet formats.
  • the clamping points are opened and the steel or metal strip in question is advanced according to the desired length of the sheet.
  • the metal or steel strip is moved with the markings of its first clamping point so that these markings overlap with the second clamping point. In this way, the material losses when cutting out the metal sheets are reduced by 50% if the clamping points and constriction points are cut out in the outlet section of the treatment line. It is only here that the metal sheets with the desired sheet formats are produced, which are brought to a stacking station on a roller table. - In the context of the invention, the steel or metal strip can be trained before stretch bending straightening in order to obtain an optimal surface finish.
  • the invention also relates to a system for carrying out the claimed method, which is characterized by a continuously operating system part with at least one heat treatment device in the strip running direction with an annealing and cooling device and with a downstream stretch-bending device and by a discontinuously operating system part with a tension stretching device and one downstream cutting device.
  • a straightening device can be arranged upstream of the heat treatment device.
  • a skin pass mill can be connected upstream of the stretch bending device.
  • the draw stretching device can be followed by a trimming device, which is consequently arranged between the draw stretching device and the cutting device.
  • a system for producing sheet metal sheets 1 and in particular large-format sheet metal sheets from hot or cold-rolled steel or metal strip 2 is shown.
  • This system has an unwinding device 3 and a straightening device 4, which adjoins the strip running direction, for eliminating coil set.
  • a heat treatment device 9 with an annealing and cooling device 9a, 9b which is preceded by a strip store 10.
  • the belt store 10 is followed by a skin pass mill 11, which is followed by a stretch bending device 12.
  • a tension stretching device 14 with a stationary clamping jaw 15 and a movable clamping jaw 16 follows, which is moved forward by hydraulic or pneumatic cylinders 17 in the course of the tension stretching.
  • the Switzerlandreck stroke is indicated by dashed lines.
  • the metal sheets 1 to be produced are still stretched in the strip state, the clamping point A remaining stationary and the steel or metal strip in question being moved from the A to the adjustable clamping point B so that the clamping marks overlap.
  • sheet metal sheets 1 and in particular large-size sheet metal sheets can now be treated in the strip state in such a way that the required flatness and freedom from tension is ensured if the steel or metal strip 2 in question is cut into sheet metal sheets 1 which are distinguished by a long service life have to.
