Straightening machine for steel wire with diameter smaller than 1 decimeter

According to the straightening machine for the steel wire with the diameter smaller than one decimeter, the steel wire is led in through a leading-in sleeve, penetrates through a hole formed by nine straightening rollers and the U-shaped bottom of a roller frame and then is led out through a leading-out sleeve, leading-out power is applied to the leading-out end, the steel wire is continuously input into steel wire straightening assemblies, and the adjacent straightening assemblies oppositely form a certain angle and height. The straightening rollers roll the steel wire, meanwhile, the motor drives the belt pulley to enable the rotor frame to rotate, the steel wire and the straightening rollers rotate relatively, the steel wire is further rolled, the steel wire is pulled in one direction through the leading-out end, tensile force between the rollers is generated, it is guaranteed that the steel wire is rolled in the pulled state, and then the straightening purpose is achieved. The screw is matched with the nu
