Description

Technical Field

[0001] The utility model relates to the field of steel production, in particular to an anti-impact device for the steel separating claw of a steel separating roller table. Background Art

[0002] The steel separating roller table is a device on a double high-speed wire production line, used to distribute the steel bars rolled out by the rough rolling mill to the first line and the second line. The steel bars rolled by the rough rolling mill are transported forward through the middle roller table of the steel separating roller table. When the steel bars approach the intermediate rolling mill, they stop running. The steel separating device of the first line starts to push the steel bars to the first-line roller table of the steel separating roller table, and the first-line roller table runs to transport the steel bars to the first line of the intermediate rolling mill for rolling. When the next steel bar stops running when approaching the intermediate rolling mill on the middle roller table of the steel separating roller table, the steel separating device of the second line starts to push the steel bars to the second-line roller table of the steel separating roller table, and the second-line roller table runs to transport the steel bars to the second line of the intermediate rolling mill for rolling, and so on.

[0003] Due to the rolling characteristics, the heads of the steel bars rolled out by the rough rolling mill will have varying degrees of bending, and the bending directions are not fixed. The temperature of the steel bars reaches 900°C, and their own stiffness is not strong. The distance between the two rollers of the middle roller table of the steel separating roller table is relatively large. Therefore, when the head of the steel bar is between the two rollers, there will be a phenomenon of tilting downward. When the elbow of the steel bar and the downward bending reach a certain degree, the head will hit the steel separating device, and the steel bar cannot continue to be transported forward, resulting in accidents. Summary of the Utility Model
