Straightening mechanism for hot rolling screw steel rod straightening and cutting machine

The utility model relates to a hot rolling screw steel rod straightening and cutting machine, in particular to a straightening mechanism for hot rolling screw steel rod straightening and cutting machine. The utility model is characterized in that five straightening blocks(6) are arranged inside a rotary cylinder(1) of a straightening mechanism. Inside a guide groove, distance between the straightening block(6) and an axial line of the rotary cylinder(1) is adjusted by an adjusting screw(2). A bearing(4)arranged at two ends of a wheel frame(5) is arranged on the straightening block(6), while a straightening roller(7) is arranged on the wheel frame(5). As the utility model adopts the designing, no scratch marks are existed on a vertical rib and horizontal rib of the hot rolling screw steel rod after the straightening, and mechanical properties of the steel rod is same as that before the straightening. .
