Abstract
The utility model discloses a continuous-casting machine flexibility dummy bar. A limiting block at the left end is located on the upper portion of the end head. A limiting block at the right end is located on the lower portion of the end head. Two adjacent chain links are connected end to end through a first pin shaft. A second pin shaft is arranged on one side of the first pin shaft. The limiting block on the right end head portion of one chain link is tightly pressed through the second pin shaft. A third pin shaft is arranged on the other side of the first pin shaft. An adjusting bolt is arranged on the third pin shaft. A gap is arranged between the top surface of the bolt and the limiting block at the left end of the other chain link. The flexibility dummy bar is particularly applicable to a square and round billet continuous-casting machine with few outer-arc supporting rollers, and a phenomenon that withdrawal speed is unstable due to crawling (bounce) of the dummy bar when casting is conducted can be avoided.
Description
Technical field
The utility model relates to a kind of conticaster flexible dummy bar.
Technical background
Dummy bar has rigidity and flexible two kinds of structures, in the main flexible dummy bar that uses chain structure in the large section square-round billet continuous casting machine, each chain link bend in one direction that can make progress.
Dummy bar enters conticaster along caster roll row under the traction of withdrawal straightening machine, block the crystallizer end opening, makes molten steel be frozen into certain thickness base shell in crystallizer and form with the dummy bar head firmly to be connected, and opens when watering, and dummy bar is pulled out two cold-zones with strand.
In large section square-round billet continuous casting machine secondary cooling zone roller be listed in interior outer arc direction dummy bar do not had clamping action, only have several rollers in two cold-zone tail region, by the guide pad of arcwall face is set between roller, when dummy bar is sent in realization to the guiding of dummy bar, for avoiding strand through out-of-date scuffing, the guide pad arc surface is lower than the outer camber line at roll surface place, adopt common chain type flexible dummy bar, when chain link process outer arc roller, because of the inside transition bending of dummy bar, wriggle (vibration), cause bleed-out when serious.
The utility model content
The purpose of this utility model is to provide a kind of conticaster flexible dummy bar, and dummy bar wriggling (vibration) phenomenon appears in the amplitude that this flexible dummy bar is bent upwards by control when avoiding the dummy bar chain link through outer arc roller.
A kind of conticaster flexible dummy bar, comprise that two ends have the chain link of limited block, wherein the limited block of left end is positioned at top, termination, the limited block of left end is positioned at the bottom, termination, the first bearing pin joins end to end two adjacent chain links, it is characterized in that: a side of described the first bearing pin is provided with the second bearing pin, and the second bearing pin compresses the limited block of a chain link right-hand member head; Opposite side at the first bearing pin is provided with the 3rd bearing pin, is provided with the adjustment bolt on the 3rd bearing pin, has the space between the left end limited block of bolt end face and another chain link.
In order to prevent from adjusting bolt looseness, cover has locking nut on the described adjustment bolt.
In order to prevent the axial float of the 3rd bearing pin, locking nut has the effect that backing plate plays axle end baffle plate.
Be bent downwardly in order to prevent each chain link by the second bearing pin in the utility model; The 3rd bearing pin, adjust the amplitude that bolt is bent upwards in order to adjust flexible dummy bar, make whole dummy bar more level off to the theoretical camber line of conticaster, when chain link can not wriggled (vibration) during through certain roller, thereby guarantee to open the stable of pulling rate when watering.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the A-A cutaway view among Fig. 1;
Fig. 4 is the state diagram after the utility model bending.
Among the figure: 1-the first chain link, 2-the 3rd bearing pin, 3-the first bearing pin, 4-the second bearing pin, 5-the second chain link, 6-adjust bolt, 7-locking nut, 8-backing plate.
The specific embodiment
Below in conjunction with accompanying drawing implementation of the present utility model is described further:
As shown in Figure 1 to Figure 3, the first chain link 1 be connected chain link 5 and connect by the first bearing pin 3, consist of the dummy bar of a chain structure, the second bearing pin 4 restriction the first chain links 1 and the second chain link 5 are bent downwardly, on the 3rd bearing pin 2 screwed hole is arranged, adjust bolt 6 by rotation, change and adjust the height that bolt 6 stretches out the 3rd bearing pin 2, the make progress amplitude of bending of control adjacent link is adjusted and is screwed locking nut 7 after complete.The 3rd bearing pin 2 adopts matched in clearance with the assembling of each chain link, automatically adjusts angle when adjacent link holds out against with adjustment bolt 6, guarantees that adjusting bolt 6 is that face contacts with the chain internode.Adjusting bolt 6 diameters can not be too small, and the one, proof strength, the 2nd, the 3rd bearing pin 2 rotations when preventing from adjusting bolt and adjacent link and holding out against, the adjustment bolt does not have the position-limiting action of expection.Backing plate 8 is fixing by locking nut 7, plays the effect that prevents the 3rd bearing pin 2 axial floats.Calculating provides when adjusting the gap d design between bolt 6 and adjacent link during the dummy bar horizontal positioned, also can be for further adjustments during use.
Large section had an area of in base, the special-shaped billet continuous casting machine engineering during the utility model can be widely used in.
