Abstract
The invention discloses an edging roll device of a rolling mill. The edging roll device comprises edging motors, speed reducers and edging rolls connected with the speed reducers. The edging rolls are arranged on an edging roll base, and an overrunning clutch is arranged between each edging motor and the corresponding speed reducer. Owning to the overrunning clutch added between each edging motor and the corresponding speed reducer, a strip stops advancing and the overrunning clutches are closed once the strip slip from the rolls, and the edging rolls are driven to edge actively and feed the strip to the rolls forcedly; once the strip is engaged and rolled by the rolls, the overrunning clutches are separated automatically due to the fact that the rolling speed is higher than the edging speed, and thus, damage to equipment due to internal stress generated by mismatching of speeds of the strip drive by the rolling motor and the edging motor is avoided. The rolls and the edging rolls have good synchronism, the quantity of the edging rolls is not required to be reduced, and broadsiding fluctuation of the rolled strip is small and is convenient to control.
