Auxiliary device for quantitative end cutting of round steel

The utility model relates to the field of off-line finishing of round steel from a rolling mill, in particular to an auxiliary device for quantitative end cutting of round steel, which comprises a support frame and a limiting plate arranged on the support frame, a plurality of mounting stations are arranged on the support frame, the limiting plate is arranged on the mounting stations, and the mounting stations are sequentially arranged at intervals along the length direction of end cutting of the round steel. After the limiting plate is installed on the installation station, the force bearing face, facing the round steel, of the limiting plate is perpendicular to the length direction when the round steel is subjected to head cutting. A worker can estimate the defect length of the end of the round steel needing to be cut off according to experience and observation of the round steel with the end to be cut off, and then the limiting plate is inserted into the mounting station with the closest length to be cut o
