Definitions

  • the invention relates to a device for cutting strands, such as clay strands for the production of ceramic products such as masonry and roof tiles according to claim 1.
  • 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. Also known Here, to use a curved sleeve to transfer the wire in a slight tilt.
  • a method and apparatus for cutting semi-plastic lightweight concrete bodies is known in which the cutting wires are clamped in rocker arms so that the wires can be moved either in constantly constantly opposite directions or simultaneously upwards or downwards through the lightweight concrete body as desired. It is advantageous that the clamped wires can be transferred via the respective tilting supports also in an inclined position for example vertical, without the wire undergoes a bend or a deflection by the cutting wire is held by the pivoting brackets on train, in rectilinear orientation.
  • This known device is not optimally used for cutting eg clay strands, as this material is in a non-plastic or semi-plastic state during the cutting process.
  • a cutting device for a clay strand in which a cutting wire is resiliently held at one end, so that a resilient support of the cutting wire is made possible.
  • the cutting wire is always aligned exactly vertically, so that the clamped wires can not be converted into an inclined position to the vertical, without the wire undergoes a kinking or deflection.
  • the device of the type mentioned above is characterized by a device according to claim 1.
  • the corresponding holders are to be moved relative to each other so that a holder for an upper end of a wire end the other for a lower end of a wire ahead or even lags.
  • the holder of the upper end of the wire is leading, so that a pulling cut is to be carried out by means of the cutting edge 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 Schrägauslegiswinkel to be set and it is ensured 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, being of the previously known concept of a vertical section of the continuously supplied extruded clay strand 2, a procedure of cutting with eg five cutting edges, namely have been passed, for example, five cutting wires. It is advantageous that result in relatively short clamping lengths of the cutting wires, resulting in significant simplifications of electronic cam to control the device, since, 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 continuously supplied.
  • the pressed from the extruder 8 Clay 2 is fed via the Justierrollen 7 the actual cutting table 5.
  • 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 centered in the cutting table area.
  • the clay strand is slightly pre-scored.
  • the cutting table itself can be moved synchronously with the clay strand via a crank drive 9.
  • the Ankantvorgang first takes place over the Ankantvortechnisch 6 instead.
  • 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 the 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 , Fig. 2.1 ), the upper holder 12 and lower holder 13 has.
  • These holders 12 and 13 are each pivotally at 14 in bearings 15 ( Fig. 4 and Fig. 6 ) stored.
  • 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, in the illustration to Fig. 2 is shown in a tensioned state before an actual cutting process.
  • 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 incise the clay strand 2 slightly in front.
  • apparent adjusting device is pneumatically operated and is used to fix the clays 2 and continue to receive cutting forces.
  • Fig. 2.1 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 has taken a skew 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.
  • the Fig. 3 to 6 shows enlarged the upper carriage 16 and the lower holder 17. From the illustration Fig. 5 It can be seen that on the upper carriage 16 is still a linear guide 26 with an adjusting screw 27 and a spring element 28 for length compensation for an inclined position 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.
  • Fig. 7b After the presentation after Fig. 7b ) These are arranged in a spaced arrangement at a distance next to each other and resiliently supported at 30 with their upper holders each. It comes, as in Fig. 7c ), to 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.
