Technical field
The present invention relates to technical field of metallurgical machinery, particularly relate to a kind of conticaster crystallizer vibrating device.
Background technology
That the frame mode of realizing the crystallizer movement locus mainly contains is guide tracked, long-armed type, compound differential type and galianconism four link type.Because guide tracked, long-armed type and compound differential type or, or because of maintenance load in using is big, or, seldom on newly-built billet caster, use because of factors such as service life are short because of complex structure.Be used in the vibration mode on the billet caster at present, it mainly is the galianconism four link type, it is the rigidity four connecting rod vibrating mechanisms with four roll articulation points, this mechanism by two rigidity shaker arms and four by rolling bearing form hinged, its design accuracy can be not more than 0.02mm, can satisfy the requirement of continuous casting manufacturing technique, but because rolling bearing when mounted, the gap error of hole axle and the wearing and tearing of bearing, use a period of time also certain shaking phenomenon can occur, the little amplitude and high frequency rate mode of vibration of carrying out at present particularly, when frequency greater than 200min
-1When above, it is not enough that the lateral stability of this structure just seems.Little amplitude also makes the lubricated difficulty that becomes of pin joint, causes the wearing and tearing of bearing, thereby causes the not steady of vibration.
On the basis of said structure, some producer when transforming original rigidity quadric chain, to wherein one be subjected to the fork of pulling force to change flexible steel plate into, the vibration of this form is called veneer spring four connecting rod vibrating mechanisms.This device has solved the side direction beat amount of original vibrating device to a certain extent, but also has two pin joints, and is still difficult in the bearing lubrication at pin joint place, easily causes the wearing and tearing of bearing, thereby causes the not steady of vibration.
A kind ofly begun on billet caster, to use, and obtained effect preferably with steel plate four bar vibrating mechanisms as fork under tension state.Because this vibrational structure does not have pin joint, therefore there are not insufficient lubrication and wearing and tearing, lateral stability is good, still bumpy motion when dither.
Summary of the invention

The technical solution adopted for the present invention to solve the technical problems is: this conticaster crystallizer vibrating device, by the vibration guiding mechanism, vibratory drive mechanism and tension-adjusting gear are formed, it is characterized in that: between the adjutage 10 of shake table 2 and stand 4, use flat spring 3, middle leaf spring 8 and following flat spring 7 connect, last flat spring 3, middle flat spring 8 and following flat spring 7 are called the inner near an end of continuous casting billets, the other end is called the outer end, the inner of last flat spring 3 connects with adjutage 10 at shake table 2, the outer end of last flat spring 3 connects with stand 4, the inner of middle flat spring 8 connects with stand 4, the outer end of middle flat spring 8 connects with adjutage 10, the inner of following flat spring 7 connects with adjutage 10, the outer end of following flat spring 7 connects with stand 4, last flat spring 3, in flat spring 8 and following flat spring 7 be arranged on three diverse locations of the casting machine radius R by center of circle O, last flat spring 3 is topmost, middle flat spring 8 is in the centre, following flat spring 7 is in the bottom, one end of following flat spring 7 is provided with tension-adjusting gear, following flat spring 7 and tension-adjusting gear can make flat spring 3 and middle flat spring 8 be in extended state all the time, to guarantee the stability of high-precision oscillation trajectory of conticaster crystallizer vibrating device and work.
Last flat spring 3 and middle flat spring 8 are respectively that a rectangle latch plate is formed, and also can be that one of them is the rectangle latch plate, and another is made up of two blocks of spring laths; Following flat spring 7 is made up of a rectangle latch plate, also can be made up of two blocks of spring laths.
The end that vibration generating arrangement 6 drives drive rod 5 is that swivel point is done little amplitude fluctuation with bearing block 11, and the other end of drive rod 5 drives vibrating grid 2 and crystallizer 1 vibration by drive plate spring 9 by adjutage 10.
Vibratory drive mechanism can also directly drive vibrating grid 2 and crystallizer 1 vibration with hydraulic cylinder by hydraulic system.
Outer end at following flat spring 7 is provided with the tension-adjusting gear (see figure 3), one end of following flat spring 7 is connected on the slide block 14 with bearing pin 18, pressing plate 19, slide block 14 slides in the groove of adjustment seat 13, be fixed with double-screw bolt 15 on the slide block 14, the other end of the double-screw bolt 15 folded spring 17 of nut 16 clamping sleeves on double-screw bolt 15, thus realize the tensioning of flat spring 7 down.
In addition, it will be appreciated that also the conticaster crystallizer vibrating device also can be arranged in the outer arc side of crystallizer, in the case, flat spring rearranges possibly, makes it keep extended state.
The invention has the beneficial effects as follows: can realize the high-precision motion track of crystallizer under dither, have and do not wear and tear, need not keep in repair and advantage such as reliable operation.
