Definitions

  • the invention relates to a device for cutting strands, for example of clay strands for the production of ceramic products such as masonry and roof tiles by means of at least one cutting edge.
  • Clay strings for the production of masonry and roof tiles are conventionally cut in a device with a cutting device to an appropriate level, wherein the cutting device has a clamped between two holders wire. It is known to guide the wire in the region of its restraint in a sleeve, so as to fix the wire position. It is also known to use a curved sleeve to transfer the wire to a slight angle.
  • the device of the type mentioned is characterized in that the holder of the cutting edge are pivotally supported in the cutting device.
  • the cutting edge or the cutting edges used, for example, clamped wires on the respective brackets can be transferred to an inclination to the vertical, without the wire undergoes a kinking or deflection by the wire by the pivoting mounts on train held in a straight line orientation. This significantly improves the service life of the wire.
  • the respective holders can be moved relative to each other so that a holder for an upper end of a wire end the other holder for a lower end of a wire ahead - or even lags.
  • the holder of the upper end of rotation is anticipatory, so that is made by the clay strand of a pulling cut by means of the cutting edge.
  • a plurality of parallel spaced apart wires are provided as cutting.
  • the device has a linear guide to receive the cutting edge.
  • the cutting edge is preferably connected to a deflectable spring.
  • the cutting edge can be adjusted in an angular range of 0 to 25 ° to the vertical, automatically adjust the holder this set angle of inclination and ensures for each angle that the corresponding cutting edge is loaded in a straight line to train.
  • the apparatus for cutting strands is numbered.
  • This device is used to make about 12,000 standard size bricks (NF bricks) per hour.
  • the device 1 is designed as a cutting table, wherein from the previous known concept of a vertical section of the continuously supplied extruded clay strand 2, a procedure of cutting with eg five cutting, namely have passed five cutting wires. It is advantageous that relatively short Clamping lengths of the cutting wires result, which results in significant simplifications of electronic cam to control the device, for example, only a synchronous time for the cutting process is correct, and beyond that additional facilities for example airing the table or the ventilation of wires can be omitted ,
  • the apparatus has a cutting table 5 with a base frame 3, a measuring roller 4 for the clay strand 2, an Ankantvorraum 6, adjusting rollers 7 for the clay strand 2 and a device 1 associated extruder 8, from which the clay strand 2 is supplied continuously.
  • the pressed from the extruder 8 Clay 2 is fed to the actual cutting table 5 via the adjusting rollers 7.
  • the speed of the clay cord 2 is determined with a roller 4.1 of the measuring roller 4, which is arranged below the clay cord 2.
  • the adjusting rollers 7 ensure that the clay strand 2 is guided laterally so that it is conveyed exactly in the center of the cutting table area.
  • the clay strand is slightly pre-tanned.
  • the cutting table itself can be moved synchronously with the clay strand via a crank drive 9.
  • the Ankantvorgang takes place via the Ankantvorraum 6.
  • the clay strand is easily pre-scored.
  • not identifiable notching tools are arranged in detail, which correspond to the contour of the Clay 2.
  • the clay strand 2 is further conveyed to the cutting table 5.
  • the cutting table has a cutting device 11, in which cutting wires as cutting 10, for example, five cutting wires or more (Fig. 7b), are arranged.
  • the cutting process is carried out transversely to the conveying direction of the extruded strand 2.
  • the cutting process takes place alternately once from the left or from the right.
  • the device 1 has the cutting device 11 (Fig. 2, Fig. 2.1), the upper holder 12 and lower holder 13 has.
  • These holders 12 and 13 are each pivotally mounted at 14 in bearings 15 (Fig. 4 and Fig. 6).
  • the holders 12 and 13 are respectively fixed in a carriage 16 (above) and 17 (below) which support additional precutting rollers 18 (above) and 19 (below).
  • a cutting wire 20 is stretched, which is shown in the illustration of FIG. 2 in a tensioned state before an actual cutting operation.
  • the carriage 16 is to be moved by a drive 21 along the guide 22, and the carriage 17 by a drive 23 along the guide 24.
  • the Vorschneidrollen 18 and 19 are located in front of and behind the cutting wire 20. During a cutting operation, they score the clay strand 2 slightly in front.
  • the apparent in Fig. 2 adjusting device is pneumatically operated and is used to fix the Clay 2 and continue to absorb cutting forces.
  • the upper carriage 16 is transferred from the drive 21 in a relation to the lower carriage 17 staggered position to the left and thus in an anticipatory cutting position in which the cutting wire 20 taken a skew has and the holders 12, 13 have pivoted in the apparent oblique position.
  • About the linear actuators can be adjusted electronically in the embodiment shown, a wire pitch of 0 ° to 25 ° to the vertical.
  • FIG. 5 shows enlarged the upper carriage 16 and the lower holder 17. From the illustration of FIG. 5 it can be seen that on the upper carriage 16 nor a linear guide 26 with an adjusting screw 27 and a spring element 28 for length compensation for an inclination of the cutting wire 20 is provided.
  • Fig. 7 illustrates schematically the Mehrschneiddrahtabschneiderkal.
  • the holders 12 and 13 with the cutting wire 20 are shown. According to the illustration of FIG. 7b), these are arranged in a multiple arrangement at a distance next to each other and each supported resiliently at 30 with their upper holders. If, as illustrated in FIG. 7c), a deflection of the wire (shown here without a movement of the upper holder 12 relative to the lower holder 13 - or vice versa), the cutting wire 20 gets into its deflected position. A corresponding length compensation can join the wire to some extent due to the resilient support.
