Definitions

the invention relates to a supporting structure for an oscillating mold with fixed vertical supports, on which support frames for Recording the mold are arranged with one another in pairs arranged handlebars on the one hand with the straps and on the other hand are articulated to the support frame.
EP 0 421 560 A1 describes an oscillation device for Continuous casting molds with a square base frame, on which two rotating drives Eccentric shafts are arranged in parallel. About the on it arranged eccentric, the oscillation can be transferred to the mold.
EP 0 150 357 describes a guiding device for an oscillating driven continuous casting mold, being on a mold lifting table Brackets are attached, each with a spring element are connected to a frame. On one in its middle area on the frame anchored spring support is a leaf spring with Distance to this arranged and fixed with its ends on this. The mold lift table is over one on the middle of the leaf spring attached intermediate piece connected to the leaf spring.
DE-OS 22 48 066 discloses a further device for guiding an oscillating continuous casting mold.
this device is the mold attached to spring elements, which are transverse to the direction of oscillation are anchored to the scaffolding. These spring elements are clamped on one side in the manner of a cantilever, the Mold is attached to the free end.
the spring elements are as multilayer spring assemblies designed in such a way that the deflection corresponding to the mold weight is at least that Oscillation stroke corresponds to the mold.
the present invention is based on the aforementioned prior art based on the task of a new solution for the suspension of the Indicate mold, which in particular a freedom of play of the Joint points guaranteed even after a long period of operation thus freedom from maintenance and freedom from wear of the joints enables and with extremely inexpensive manufacture of the mold suspension none pronounced with regard to the spring / mass system Has natural resonance and extremely precise guidance of the oscillating Mass allows.
the invention proposed that the handlebars with the carriers and Support frame are connected by means of movable hinges, the Hinges are designed as leaf spring hinges.
FIG. 1 shows a supporting structure for an oscillating mold 10 (FIG. 2) with two fixed vertical supports 1, each of which a support frame 2 is arranged with one another arranged in pairs horizontal links 3, on the one hand, with the supports 1 and on the other hand are articulated to the support frame 2.
the support frames are with vertical supports 5 and with cantilever arms 4 trained to accommodate the mold 10. Between each carrier 1 and the vertical support 5 parallel to it at a distance are these connecting horizontal handlebar 3 arranged with hinges.
the hinges are designed as leaf spring hinges 20. This As previously pointed out, leaf spring hinges are maintenance-free and extremely wear-free in their joints inexpensive to manufacture leaf spring connections.
the drive can for each of the two support frame 2 by a hydraulic cylinder 11 occur, i.e. it is not a hydraulic system with complex synchronization devices required.
the foundation must be extremely favorable leverage does not take up a double load.
the spring / mass system also has no natural resonance. As a result, it is provided that only 4 below each cantilever a drive member 11 the oscillating drive of the support frame 2nd effected with the mold 10.
This bar 12 is horizontal at one end Leaf spring hinge 20, 20 'on the carrier 1 and on the opposite End over a similar leaf spring hinge 20, 20 'with the vertical support 5 articulated.
Each leaf spring hinge 20, 20 ' is about a horizontal one Swing axis x-x designed and arranged to be swingable.
the cross section of a leaf spring hinge 20, 20 ' should advantageously be designed so that its moment of inertia in the direction of deformation is small and large in the direction of leadership. That is, the Tensions created by the movement are smaller than that permissible stresses for alternating bending stress. In the direction of leadership May the deformation due to that caused by the executives arising voltage, however, only be very small.
a particularly inexpensive manufacture of the leaf spring connections results from the fact that the free ends of each leaf spring hinge 20, 20 'by means of screw connections 13 Clamped connections clamped in horizontal slots 14, 14 ' are held.
Fig. 2 shows a complete support structure for an oscillating Mold 10, wherein the same elements with the same reference numerals are provided. 2 is the constructive one Straightforwardness and practicality of the supporting structure according to the invention for an oscillating mold 10 clear to the person skilled in the art recognizable.
