Definitions

  • the invention relates to a mold oscillation device for a continuous casting installation, a frame-like mold lifting table carrying a mold or the mold itself being connected via connecting rods to eccentrics arranged on a rotary drive shaft, the lifting height of the oscillation adjustable and the connecting rod acting on defined points of attack of the lifting table or the mold .
  • a mold oscillation device with lifting height adjustment is known from European Patent 0 207 055.
  • the mold oscillation is carried out via connecting rods mounted thereon, which are connected to the mold lifting table via fastening means.
  • the lifting height is adjusted by rotating the eccentric bushing relative to the rotary shaft.
  • the position of the eccentric bushing corresponding to the selected lifting height, with respect to the eccentric part of the shaft, can be fixed by means of a flange and counter flange through connecting pieces passing through it.
  • the disadvantage here is the time-consuming conversion when the lifting height has to be changed.
  • the invention aims at eliminating this disadvantage and has as its object to provide a mold oscillation device of the type described in the opening paragraph which enables the lifting height to be changed quickly and safely.
  • An advantageous construction is characterized in that the piston has a lateral projection and the coupling means between the eccentric and the lifting table or mold consist of cylinders with stamps arranged displaceably therein, the cylinders being fastened to the lifting table or the mold, the stamp on the end face of the piston can be pressed, and the piston can be fixed against an abutment via the projection.
  • One of the abutments is rigid, i. H. firmly connected to the cylinder.
  • Each additional abutment consists of a movable ring stamp and can therefore be changed in position.
  • the stamp and ring stamp can be acted upon hydraulically.
  • the respective cylinders of all points of attack assigned to the same lifting height are each connected to a control circuit.
  • Fig. 1 shows the use of the object according to the invention in a known square arrangement.
  • Two parallel eccentric shafts mounted on a supporting frame 15 are driven by corner gears 9 with a drive motor 10 with drives on both sides.
  • Each of the four points of attack 11, 12, 13, 14 in the exemplary embodiment shown consists of one of the eccentric units described in the invention.
  • the pistons of the same stroke height of all points of attack are each connected to a remote-controlled control circuit.
  • the stroke height is selected by selecting the cylinder in which the piston is guided with the appropriate eccentricity.
  • the selected cylinder actuates the punch 6 contained therein and presses it against the end face of the piston, the piston being pressed against the abutment 7 or 7 'via its lateral projection 4'.
  • the non-positive securing of the piston, both on the front side and on the lateral projection ensures a non-positive coupling with the mold lifting table or the mold, both during the upward and downward movement of the Oscillation.
  • the cylinders 5 arranged per point of application are expediently designed as a coherent cylinder block 5 'or eccentric unit.
  • the abutments 7, 7 'in the cylinder blocks 5' consist of ring punches 7 'fitted therein, the abutment, which is assigned to the piston with the greatest eccentricity per eccentric unit, being designed as a rigid abutment 7.
  • the various eccentrics arranged on the rotary shaft for each point of application are arranged in phase.
  • the application of the punches 6 and ring punches 7 'by hydraulic means named in the exemplary embodiment can also have the same effect by magnetic, electrical or motor means.
