Definitions

  • the invention relates to a device for cutting a strand according to the preamble of claim 1.
  • a device for cutting a strand according to the preamble of claim 1.
  • Such a device is used in particular in the production of moldings made of clay or the like for the construction industry, in particular bricks.
  • a brick cutting machine which has a hydraulic transverse drive.
  • a massive pivot arm pushes against a steel beam which in turn drives forward V-shaped vertically spaced slide arms whose corresponding end faces are vertically connected via cutting wires. With each thrust of the system, the cutting wires are pushed through the clay string, thereby splitting it.
  • a strand cutting device is disclosed, with a cutting block the means of mounted cutting bracket.
  • the drive of the cutting device via a clutch, a gearbox and a disc with an eccentrically mounted bolt automatically.
  • the invention is based on the object to improve a device of the type described above with respect to the transverse guide or the transverse drive for the holder. This object is solved by the features of claim 1. Advantageous developments of the invention are described in the appended subclaims.
  • the transverse drive on two drive elements which engage in a direction along the conveying direction distance from each other on the holder.
  • an uneven distribution of the cutting forces on the holder and its transverse guidance is avoided and achieved a uniform distribution of the cutting forces.
  • Another advantage is that the guide surfaces are less stressed and therefore a long life is achieved. Due to the improved guide or drive situation, it is also possible with a sufficient guidance, the guide length of the guide body relatively short, so that the design size can be reduced in the guide direction of the transverse guide.
  • the embodiment of the invention is particularly well suited for such devices in which two or more, one along the conveying direction directed distance from each other having cutting wires are held on the holder, which make it possible to perform multiple cuts simultaneously in a transverse movement of the holder.
  • Another advantage of the embodiment of the invention is therefore that an efficient device is achieved, which is also characterized by a simple design.
  • the embodiment according to the invention with a plurality of cutting wires arranged one behind the other in the longitudinal direction of the passage is also particularly well suited in combination with a device designed for bidirectional cutting, in which a spreading of the cut strand sections is not required.
  • a device of this combination is characterized by high performance with low design, construction and control effort, with a stabilized support of the holder or the transversely opposed holder is achieved in the cutting motion.
  • hinge rods and pendulum lever which ensure small and simple constructions in the transverse direction.
  • a lever drive also allows a simple way to change the stroke length of the drive elements. It is possible to increase the stroke length only in one direction or reduce and thus adapt to a desired transverse dimension of the strand, with an end point of the stroke length always remains the same, as it is set constant by the support of the clay string on the conveyor.
  • the holder transversely to the conveying direction is formed as a continuous and thus closed frame.
  • a holder in the longitudinal and transverse guide which is preferably driven vertically by a respective arranged on the associated side drive.
  • the drawing shows the device according to the invention for cutting a strand of plastically deformable material, in particular clay, in longitudinal sections, preferably brick, in side view.

  • a plurality of cutting wires 1a extending transversely to the longitudinal central axis 2 can be arranged on the holder 1, which have a distance a extending from one another along the longitudinal central axis 2.
  • Two or more cutting wires 1a preferably three or four or more cutting wires 1a, may be fastened to the holder 1, as the drawing shows by way of example.
