Definitions
- the invention relates to an oscillation device for continuous casting molds according to the preamble of claim 1.
- a mold oscillation device of the generic type is known from German Offenlegungsschrift DE-A-19 09 710.
- the oscillation device consists of a square base frame, in which cams are mounted on the opposite end faces, which are driven by drive devices consisting of a shaft and a drive motor.
- the mold is fastened in a rectangular mold support frame, on the underside of which bottom rollers are attached in the corners, which rest on the cams and transmit the oscillation to the mold.
- the mold support frame is held by guide devices which are each arranged in the middle of the sides of the support frame, the guide devices having vertical rails and guide rollers which are in engagement with the rails.
- the disadvantage here is that there is too much play between the guide rails and guide rollers due to wear, which on the one hand means that bottom rollers and cams no longer lie centrally one above the other and on the other hand that exact guidance of the mold or the mold support frame is no longer guaranteed.
- a mold support frame must be used for the storage of the mold, so that a correspondingly large mass has to be recovered during oscillation.
- this arrangement proves to be disadvantageous when the mold is replaced.
- the invention is therefore based on the object of providing an oscillation device for continuous casting molds which has the smallest possible mass to be moved and an exact one Ensures synchronism of movement with the intended strand path.
- a device of the generic type according to the invention in that the mold is fastened in a centrally recessed opening of a support plate, that a wear plate is arranged at each corner of the support plate, the wear plate being supported on an eccentric outer ring which is supported on the rotationally driven eccentric is rotatably mounted and that spring bars arranged parallel to the edges of the support plate can be connected to the base frame at the corner points and to the support plate between the corner points.
- the respective connection between the spring bar and the support plate is made by means of a sheet which is detachably connected on the one hand to the spring bar by screws and on the other hand to the support plate by means of a wedge connection.
- connection between the spring bars and the corners of the base frame consists in each case of a mounting bracket fastened to the base frame and a cuboid fastening element arranged at the respective end of the spring bar, which can be displaced parallel to the longitudinal axis of the spring for adjusting the mold and can be non-positively connected to the mounting bracket and the spring bar in the operating state is.
- the eccentric shafts arranged in parallel can preferably be driven in opposite directions to one another.
- the advantages achieved by the invention consist in particular in that, on the one hand, the weight saving makes it easier to change the mold and the driving force is reduced, and on the other hand the wear of the oscillation device itself is reduced.
- the lateral migration of the mold during the oscillation is prevented by the laterally arranged spring bars, which are quickly detachably connected to the connecting plates by screws and the connecting plates to the support plate by means of wedge connections.
- the mold 1 shows an overall view of the elements arranged in the device.
- the mold 1 is fastened in the middle in the recessed opening of the support plate 2 and lies on the eccentrics 4 at the corners of the support plate with wear plates 3 attached there.
- the spring bars 6 arranged laterally around the support plate 2 are connected to the base frame 7 itself at the corners of the base frame 7 via support brackets 10.
- the sheets 8 serving as connecting elements between the spring bars 6 and the support plate 2 are each arranged centrally on the sides of the support plate 2.
- the connecting plates 8 are connected on the one hand by a screw connection 9 'to the spring bars 6 and on the other hand by a wedge connection 9 to the support plate 2.
- the eccentrics 4 arranged under the wear plates 3 are driven by two parallel eccentric shafts 5,5 '.
- the eccentric shafts 5,5 ' are themselves with the corner gear 12 Drive motor 13 connected.
- As a drive motor either a motor with drives on both sides, which is arranged between the corner drives, or a drive motor, which is arranged outside the corner drives, can be used.
- an eccentric outer ring 4 ' is arranged in stock, which carries out the implementation of the rotary movement of the eccentric or the eccentric shaft 5.5' in a lifting movement, and by the abutment of the wear plate 3 on the eccentric outer ring 4 'the oscillation transfers to the support plate 2 or mold 1.
- Figure 4 shows a section through the spring bar 6 and its connection to the support plate 2.
- the spring bar 6 contains a thickening 6 'in the center, through which holes 6' 'are passed. These bores 6 ′′ serve to produce a detachable screw connection 9 ′ with the connecting plate 8.
- the connecting plate 8 is quickly detachably connected to the support plate 2 via a wedge connection 9.
- Figure 5 shows the top view of a spring bar.
- the centrally arranged thickening 6 ' can be seen and the connection to the support plate 2.
- fastening elements 11 are arranged through which holes are passed which connect the spring bar 6 to the base frame 7 via the support brackets 10 do.
- These fasteners 11 are designed so that they can be moved slightly for adjustment in the direction of the longitudinal axis and in Operating state with the support brackets 10 are non-positively connected. This enables the spring bars 6 to be re-tensioned.
- the oscillation device is designed in such a way that all types of molds, e.g. H. straight molds but also curved molds can be used. Furthermore, the design of the eccentric 4 with the eccentric outer ring 4 'is designed such that conventional eccentric adjustment devices for selecting different oscillation amplitudes can be inserted at this point.
- the compact but relatively simple construction also enables a quick change of a strand guide segment attached to the base frame.
