Definitions

  • the invention relates to a clamping device for clamping a mold on a lifting table, wherein the mold can be supported on the lifting table by means of laterally projecting support straps and can be clamped on the lifting table by means of tie rods passing through the support straps.
  • a tensioning device of this type is known from DE-A1-27 00 498, the mold being fixable on the lifting table by means of wedges penetrating the tie rods.
  • this clamping device is very robust, it requires that the wedges be pushed out or in to loosen or attach the mold from or on the lifting table, which is time-consuming.
  • To securely attach the mold to the lifting table it is necessary that the wedges have only a very small wedge angle. For this reason, it is necessary to adapt the wedges to the recessed part of each tie rod which passes through the support lugs before driving in, which represents a considerable expenditure of time.
  • the invention aims at avoiding these difficulties and has as its object to create a clamping device which allows a very quick mold change or mold removal, whereby force-requiring manipulations and effort in making the process are avoided.
  • This object is achieved in that the tensioning device out as a quick release device is formed, which is formed from two sleeves each, which are provided with mutually corresponding screw-shaped sliding surfaces, which form a thread, wherein a sleeve of the quick release device is each provided with a tie rod of the mold passing through tie rod.
  • a preferred embodiment is characterized in that a bushing is rigidly connected to the tie rod, the tie rod having its end projecting through the bracket being fixable in its longitudinal direction on a bracket, preferably by means of an insert.
  • a particularly robust construction of the tensioning device according to the invention is characterized in that; that the sleeve provided with the tie rod on the lifting table is non-rotatable, but is vertically displaceable in the axial direction of the tie rod, and the second sleeve is arranged between the sleeve provided with the tie rod and a support part of the lifting table and can be rotated by means of a pressure medium cylinder.
  • the helical sliding surfaces of the bushes are appropriately inclined at an angle of inclination that is smaller than the associated friction angle.
  • a structurally particularly simple clamping device is characterized in that two rotatable sleeves adjacent Schnellspannvorrichtun are g s connected by a common pressure-medium cylinder.
  • the bushings are in an off position Take the lift table arranged.
  • FIG. 1 shows a section through a strand guide frame of a continuous casting installation in a schematic representation
  • FIG. 2 shows a plan view of the mold with the cover plate lifted off.
  • a mold 1 is supported on a frame-shaped lifting table 3 by means of laterally projecting support straps 2. Casters 4 form a unit with the mold 1 and oscillate with this ..
  • the lifting table 3 is set in motion during casting by an oscillation drive (not shown).
  • the cast strand emerging from the mold 1 in a straight form is deflected into a circular path by the part 6 of the strand guide, which contains bending rolls 5, which adjoins the mold.
  • This strand guide part 6, hereinafter called the bending zone is arranged in a support frame 7, the supports 8, 8 'of which extend to the upper edge 9 of the mold 1.
  • the support frame 7 is mounted on a stationary steel frame 10 via hooks 11, into which an upper cross member 12 of the support frame 7 engages.
  • Each hook 11 can be precisely adjusted with washers 13, which can be inserted under its vertical and horizontal bearing surfaces on the steel frame 10, so that the support frame 7 with the bending zone 6 is precisely aligned with a subsequent strand guide part 14, drawn in broken lines in FIG. 1 can be.
  • a lower cross member 15 on the side of the hook 11 of the support frame 7 lies against the steel frame 10 without play.
  • the vertical supports 8, 8 ' have horizontal support surfaces 19, which are opposed to support surfaces 20 of the mold 1 with a play 21 which enables the mold to oscillate.
  • the support surfaces 20 of the mold 1 come into contact with those of the supports 8, 8 '.
  • the mold 1 is also lifted.
  • Each quick clamping device 22 has two with a thread education dendenschraubenförmigei g guide surfaces 23 provided bushings 24, 25, of which a sleeve is mounted vertically displaceably and non-rotatably in the lifting table 3 24, the second bushing 25 while the axis 26 of the first sleeve by means of a pressure cylinder 27 is rotatable.
  • the non-rotatable bushing 24 is rigidly connected to a tie rod 28 which projects vertically upward through the cover plate 29 of the lifting table 3 and further through one of the laterally projecting support straps 2 of the mold 1.
  • a recess 30 is provided, into which an insert 31 can be inserted, which insert 31 engages over the carrying tab of the mold.
  • the contact surfaces 32 of all support brackets 2 on the upper side of the lifting table 3 have a high friction factor, so that the mold is reliably fixed by means of the rotatable bushes 25 after the tie rods 28 have been tightened.
  • the helical sliding surfaces 23 of the bushes 24, 25 have an angle of inclination, which is smaller than the associated friction angle, so that after the bushings have been tightened, the pressure medium cylinders 27 which tension the bushes no longer have to be acted upon by pressure medium.
  • two rotatable sleeves arranged on one side of the mold are connected via levers 33 by means of a single pressure medium cylinder 27.
  • the support surfaces 19 and 20 have a low friction factor, so that it is possible to move the mold 1 relative to the bending zone 6 when the mold is seated on the support frame 7 of the bending zone 6.
