The diameters of the upper working roll and the lower working roll are 80-250mm, and the diameters of the supporting roll and the lower supporting roll are 39-120 mm.
Two ends of each lower working roll are arranged in a lower roll system bearing block which is arranged at the lower part of the machine frame.
The oil cylinder is opened quickly, the oil cylinder is called as an oil cylinder for short, the speed of the oil cylinder is 80mm/s, and the speed of fine adjustment of the speed reducer is 2 mm/s. The speed of the oil cylinder is higher than the fine adjustment speed, and the oil cylinder is mainly used for opening when threading, only two limit positions, namely the longest limit position and the shortest limit position, can be accurately positioned at any position by the speed reducer, and is used for adjusting the position of a working roller when the straightening machine works to ensure the straightening effect. Therefore, the oil cylinder is opened quickly.
The supporting roller comprises a shaft, a roller sleeve is sleeved outside the shaft through a bearing, and two ends of the shaft are fixed on the arc supporting surface of the cross beam. The roller sleeve supports the working roller and can rotate along with the working roller, so that the supporting effect is achieved.
The utility model discloses increase independent support below every upper/lower working roll, solved upper/lower working roll intensity problem, the upper working roll possesses the function of independent adjustment simultaneously, and the adjustment of upper working roll includes the coarse adjustment of realizing by oil cylinder piston rod is flexible from top to bottom and the fine setting that is realized by the reducing gear box.
