The round steel bar straightening machine is a straightening equipment for the metal bar,bar,pipe and wire rod.The straightening machine squeezes the rod through the straightening roller to change its straightness.It usually has two rolls of straightening rollers.The roller is rotated by the rotating rod or the friction of the pipe.For the straightening transmission system, the transmission mode of motor,reducer gear distribution box,safety coupler and universal coupling to the straightening roller is generally adopted.During its producing process,the quality of it is always strictly controlled.Rollers are adjustable to the desired position,the machines can be offered with stepless variable speed.
