摘要： A straightening method is presented where a concave roller, which has a roller caliber and in which the projection of the roll caliber forms an arc with respect to the cross section of a pipe. The projection arc radius can freely be changed by adjusting the angle between the roller axis and the axis line of the pipe. A plurality of concave rollers are arranged on the outer surface of the metal pipe in the circumferential direction, and rolling is applied on the outer diameter of the pipe while revolving these rollers about the pipe axis.

摘要： A STRAIGHTENING MACHINE FOR ROUND TUBULAR OR BAR STOCK WHEREIN THE STRAIGHTENING ROLLS ARE ADJUSTABLE RADIALLY TOWARD AND AWAY FROM AS WELL AS ANGULARLY WITH REFERENCE TO THE PATH OF TRAVELLING STOCK. THE ROLLS ARE DISPOSED IN GROUPS AND EACH GROUP OF ROLLS CAN BE MOVED RADIALLY OR ANGULARLY BY ONE OF SEVERAL INPUT SHAFTS WHICH EFFECT ADJUSTMENTS OF ROLL HOLDERS BY WAY OF PLANETARY TRANSMISSIONS.

摘要： Provided is a rolling straightening machine which enables outer-diameter-reducing rolling and straightening rolling of a pipe or tube material or a bar material at high speed with high accuracy. The rolling straightening machine includes at least two rollers arranged across a pass line of a pipe or tube material or a bar material, the at least two rollers having a gap therebetween, the gap being defined by an outer-diameter-reducing rolling portion having a diameter reduced from an upstream side toward a downstream side in the rolling straightening machine and a straightening rolling portion continuous from an exit side of the outer-diameter-reducing rolling portion toward a downstream side of the rolling straightening machine, the rollers having shapes which are symmetrical about the pass line in the outer-diameter-reducing rolling portion, and in the straightening rolling portion, asymmetrical to the pass line in the outer-diameter-reducing rolling portion.

摘要： Wire is straightened as an incident to being pulled through axially spaced upstream, intermediate and downstream straightening dies carried within a rotating arbor. Each die is formed with a groove which is specially shaped to cause the wire to tend to follow its natural path as the wire is straightened, the shape of the grooves reducing high stress concentrations on the dies and increasing the service life thereof.

摘要： The present disclosure relates to the machines for straightening pipes, particularly thin-walled ones, in the process of their motion. The machine comprises the feeding mechanisms and holders with straightening rolls, said holders located between said feeding mechanisms; said holders are cantilevered on the supports (speed reducers) moved along the pipe feed axis. The holders have roll-holding pins with bushings and washers connected correspondingly with gears. Each holder has two gearwheels meshing with said gears. In each holder the gearwheel meshing with the gear of the bushing is intended for simultaneous radial displacement of all the straightening rolls of this holder while the gearwheel meshing with the gear of the washer is intended for simultaneous angular displacement of all its straightening rolls.
