Definitions

  • the present invention relates to a device for producing reinforcement cages from reinforcement grids with transverse and longitudinal wires.
  • reinforcement cages such as those required for the production of concrete slabs, are manufactured in several work steps, some of which are purely manual work steps.
  • the object of the present invention was to provide a device which creates a reinforcement cage from a reinforcement grid in one operation.
  • the device according to the invention in that it has a support bench for the reinforcement grid, a longitudinal beam arranged at a distance above it with two carriages movable thereon, with at least one lowerable or lowerable on the carriage.
  • Liftable column is arranged, which is provided at its end with at least one gripper and that a bending mandrel device is provided in the support bench, which can be extended or retracted from the support bench to the reinforcement grid. is retractable.
  • the device according to the invention has a support bench 1, on which a reinforcing mesh 2 to be bent into a cage is positioned, as shown in FIG. 1. Additional support elements 3, 3 'are provided for supporting the reinforcement grid 2. Above this arrangement there is a carrier 4 on which two carriages 5, 6 are movably attached.
  • the carrier 4 is an I-profile carrier, for example.
  • the carriages 5, 6 can be moved along the carrier 4 by suitable drive means.
  • Each carriage has at least one column 7, 8 which can be extended downwards. At the end of this column, a box 9, 10 is attached, from which a gripper arm 11, 12 can be extended.
  • the gripper arm 11 can be extended at an angle of 45 ° from above with respect to the reinforcement grid plane, while the gripper arm 12 can be extended horizontally parallel to the reinforcement grid plane.
  • the gripping arms 11, 12 are provided with gripping means 13, 14, which can grip cross wires 2 'of the reinforcement grid 2.
  • a further column with a gripping arm is provided parallel to the column 8, which column is not shown in FIG. 1.
  • a bending mandrel device 15 is present in the support bench 1, which is shown here in its parking position below the reinforcement grid 2.
  • the mandrel device 15 can be moved from this position upwards through the mesh of the reinforcement grid 2.
  • the bending mandrel can then, for example, be brought over a cross wire 2 ′ of the reinforcement grid 2 and hooked onto it in order to hold the reinforcement grid 2 on the support bench and to bend the longitudinal wires about the support bench axis.
  • the bending can, however, also take place in the same way at any point on the longitudinal wires of the reinforcement grid.
  • a mandrel is provided for each line wire. It is clearly evident that the mandrel has a double function here.
  • the wire serves as a hold-down device for the wire, and on the other hand it determines the bending radius of the wire to be bent by its shape.
  • the bending mandrels themselves having several, preferably two, different radii of curvature, reinforcement gratings with different wire diameters can be processed without the need to first replace the bending mandrels. It only has to be ensured that the area of the bending mandrel provided with the appropriate radius of curvature lies over the wires to be bent.
  • the reinforcement mesh 2 can be processed for a number of applications.
  • Reinforcement grids with or without spacer elements attached to the wires can thus be moved, for example from a production machine into a magazine. Or only the wire ends of a reinforcement grid can be bent. Entire reinforcement cages can also be created fully automatically, as described below, for example. The automation of these processes is less expensive than the conventional, manual way of working and faster.
  • FIG. 2 shows how both gripper arms 11, 12 engage the last transverse wires of a reinforcement grid 2.
  • the bending mandrel device 15 is in its parking position. By moving the two carriages 5, 6, the reinforcement grid 2 is shifted to the right into the position shown in FIG. 3. Here the mandrel device 15 is now pushed upwards through the space between two transverse wires of the reinforcement grid. The reinforcement grid is then moved again to the left by means of the gripping arms 11, 12 until a cross wire 2 'comes into contact with the mandrel holder 15', as shown in FIG. 4. In this position, the bending mandrel 15 is moved downwards until it engages with the corresponding transverse wire 2 ', as shown in FIG. 5.
