Description

Device for preventing roller of vertical rolling mill for producing deformed steel bar by three-segmentation

Technical Field

The utility model belongs to the technical field of the three segmentation production techniques of the screw-thread steel of iron and steel enterprise and specifically relates to a prevent that three segmentation production edgers of screw-thread steel from falling device of roller.

Background

With the continuous progress of the three-segmentation process technology in the steel industry, the steel enterprises face more and more challenges. One of the reasons that the yield of the deformed steel bar three-cutting production is not high is that the rolling defective products are increased due to uneven cutting. In order to ensure the uniformity of the three-cutting of the deformed steel bar and reduce rolling defective products, a vertical rolling mill is often used for pre-cutting the previous pass, the rolling mill of the type belongs to a two-roll rolling mill, and the uniformity of the cutting can be ensured only by ensuring the standard and stability of the material type of the pass on a deformed steel bar production line. However, due to the influence of the specificity and gravity of the two-roll vertical rolling mill, the outer roll of the two-roll vertical rolling mill on the line may automatically fall for a certain distance due to the self weight, so that the material shape deviation is caused, the uniformity of the three-slitting is further influenced, and the number of rolling defective products is increased due to uneven slitting.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is exactly in order to solve the problem that the roller was easily fallen to the three segmentation production edgers of present deformed steel bar, provides a device that prevents that the three segmentation production edgers of deformed steel bar from falling the roller, can prevent effectively that the three segmentation production lines of deformed steel bar from stopping because of the trouble that the roller brought falls, reduces the wastrel on the three segmentation production lines of deformed steel bar, reduces the adjustment time of stopping time, improves the operating rate, increases output.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a prevent that thread steel three segmentations from producing vertical rolling mill from falling device of roller, is including setting up the roll on the rolling mill seat, and the roll is connected on the roll chock, even has the steel sheet of cuboid on the roll chock, and a fixed ear is connected respectively at the upper and lower both ends of steel sheet, all is equipped with the round hole on every fixed ear, and the round hole in-connection has matched with bolt and nut, and the steel sheet passes through the bolt and nut and links to each other with the roll chock fastening.

Further, the axis of the steel plate is arranged parallel to the axis of the roll.

Further, the round hole is a round hole with a threaded inner thread and the diameter of the round hole is 30 mm.

Further, the steel plate is arranged on the outer side of the roll chock and is perpendicular to the roll chock.

Furthermore, the fixing lugs and the steel plates are perpendicular to each other, and the bolts vertically penetrate through the round holes in the fixing lugs and are fastened and connected with the nuts matched with each other.

The technical scheme of the utility model in, through fixing the steel sheet parallel with one side at the vertical rolling mill bearing frame of two roller with bolt and nut and guarantee that the nut fastening targets in place to prevent that the outside roll from dropping because of the dead weight, the utility model discloses a device has effectively prevented when the trouble that the deformed steel bar three-segmentation production line brought because of falling the roller stops to adjustment time when reducing and stopping also can reduce the production of rolling wastrel simultaneously, thereby increase of production.

Detailed Description

Example 1

For the present invention to be more clearly understood, the following is a further explanation of the device for preventing the deformed steel bar from falling off the roller of the vertical rolling mill, and the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

Referring to fig. 1, a prevent that deformed steel bar three-segmentation production vertical rolling mill from falling device of roller, including setting up roll 2 on rolling mill seat 1, roll 2 is connected on chock 3, its characterized in that:

the roller bearing seat 3 is connected with a cuboid steel plate 4, and the axis of the steel plate 4 is parallel to the axis of the roller 2;

the steel plate 4 is arranged on the outer side of the roll chock 3 and is vertical to the roll chock 3;

the upper end and the lower end of the steel plate 4 are respectively connected with a fixing lug 5, and the fixing lugs 5 are perpendicular to the steel plate 4;

each fixing lug 5 is provided with a round hole 5a, and the round hole 5a is a round hole with a threaded inner tooth with the diameter of 30 mm;

the round hole 5a is internally connected with a bolt 6 and a nut 7 which are matched with each other, and the steel plate 4 is tightly connected with the roll chock 3 through the bolt 6 and the nut 7.

When the screw-thread steel normally produces, will the utility model discloses a bearing frame assigned position is installed to the device, can normally use, the utility model discloses a device preparation is convenient, easy operation has solved the roller problem that falls, has reduced the off-time on the three segmentation production lines of screw-thread steel, and then has improved screw-thread steel production operation rate, has increased output.
