Definitions

  • the invention relates to an adjustable plate mold with between broad side walls clampable narrow side walls, each in the upper as in the lower after outer edge area of the narrow side walls to one actuator each are articulated, which are mounted on a cassette holder.
  • DE-OS 29 23 113 describes a method for changing a strand cross-sectional format and a mold for carrying out the method known, in which the Narrow side walls are hinged actuators, which in one Chill side walls surrounding frames are stored.
  • the actuators are can be operated independently and at least one actuator is on the Frame articulated, i.e. a pivoting movement in the to the broad side walls allowing parallel plane of symmetry, stored.
  • Adjustment devices of molds of this type have the disadvantage that at least outside the clamping phase of the narrow side walls through the Broad side walls the adjusting device has to absorb transverse forces.
  • the invention has become known with the knowledge of the above. Disadvantages set the goal to create an adjustable mold, using simple constructional means, The horizontal position of the narrow side walls is unobstructed and requires little maintenance can be specified while changing the slab format.
  • holding parts are provided which cover the narrow side walls Hold the predeterminable horizontal line. These holding parts form together with the actuators and the narrow side walls or the cassette holders Truss. Due to this particularly rigid construction, any roll movement is prevented of the narrow side walls prevented. At the same time, the desired location of the Narrow side walls adhered exactly, especially outside the clamping phase of the Narrow side walls through the wide side walls.
  • the holding part is a rod that is at an angle to each narrow side wall is guided and its length can be changed.
  • the rod is attached to the cassette holder at the other end and diagonally to that of the actuators, the narrow side walls and the Cassette holders formed frame out.
  • two are diagonal Arranged rods provided as piston-cylinder units or as electric linear drive are designed.
  • the rod has a thread that corresponds to a spindle nut which is attached to the cassette holder.
  • This rod is dimensioned so that it can safely take over the expected tensile and compressive forces.
  • the spindle nut is also actuated in a corresponding translation and the length of the diagonal bar of the truss is changed accordingly.
  • the holding part is a rope that is connected to a drivable rope drum arranged on the cassette holder. Since a rope can only absorb tensile forces, as far as the holding part also has to absorb compressive forces, a second rope is installed, which is arranged symmetrically with respect to the first tether and quasi takes over the compressive forces through the reversal.
  • the holding part is a simple rod that is connected to a two-armed lever.
  • the arm connected to the staff The two-armed lever is dimensioned so that it is negligibly small Bending forces take over, so that the rod together with the narrow side walls and the actuator forms a fully-fledged framework.
  • a measuring and control device is provided for safe broadside adjustment, the control technology with the actuators on the one hand and the drives of the holding part connected is.
  • a mold 11 is shown on both sides Has side walls 12 and narrow side walls 13 and 14 respectively.
  • the individual narrow side walls 13 or 14 are connected via actuators 31 and 32, respectively Cassette holders 21 or 22 connected.
  • the actuators 31 are a type that on the cassette holder on the respective narrow side wall 13th or facing 14.
  • the actuator 32 is with its drive part on the Mold 11 is arranged on the side facing away from the cassette holder 21 or 22, the Drive shaft is guided by the respective cassette holder 21, 22 and articulated on the narrow side wall 13 or 14 is attached.
  • a pump 33 is provided for media supply.
  • a rod 44 that can be changed in length is provided supported at one end on the cassette holder 21 and at an angle a to Narrow side wall 13 is guided.
  • a drivable cable drum 45 is in the left part of the drawing Head of the cassette holder 21 arranged on a rope 42, which on a Breakpoint 23 of the narrow side wall 13 is fastened with the narrow side wall 13 connected is. Due to the dead weight of the narrow and broad sides 12 to 14 the rope 42 exclusively and sufficiently stressed in train.
  • a rope drum 45 is provided, from which two ropes are guided around the cassette holder 22 via rollers 48 Narrow side wall 14 provided stops 23 and 24.
  • the intersecting ropes 42 which are subjected to tension thus fulfill the function of a holding rod which Can absorb tensile and compressive forces.
  • a rod 44 is provided in the left part, which is at an angle a to Narrow side wall 13 is guided and at the other end a drivable spindle nut 47 having.
  • the drive of the spindle nut 47 is control engineering with a measuring and Control device 51 connected to the actuators 31 in conjunction is to coordinate the movement of the narrow side wall 13 during the Width adjustment.
  • a rod 44 is provided, which ends at one end Breakpoint 23 of the narrow side wall 14 is articulated and at the other end is connected to a rocker arm 43, which is operated by a rocker arm drive 46 is drivable.
  • the rocker arm 43 is a two-armed lever, the one with the rod 44th connected lever arm is so strong that it has almost no bending is subject.
  • the drive 46 of the rocker arm 43 is in turn control technology with a measuring and Control device 51 connected.
