Definitions

  • the present invention relates to a take-up device for a pipe produced in a rolling mill and to a rolling mill with such a take-up device and to a method for winding a finished pipe.
  • an extended hollow cylindrical blank is usually cold reduced in the fully cooled state by compressive stresses.
  • the blank is formed into a tube with a defined reduced external diameter and a defined wall thickness.
  • the most common pipe reduction method is known as cold pilgering, the blank being called billet.
  • the billet is rolled over a calibrated, i. the inner diameter of the finished tube, rolling mandrel pushed while calibrated from the outside of two calibrated, i. comprising the outer diameter of the finished tube defining rollers and rolled in the longitudinal direction over the rolling mandrel.
  • the billet undergoes incremental advance toward or beyond the mandrel, while the rolls are reciprocated horizontally over the mandrel and thus over the billet.
  • the horizontal movement of the rollers is predetermined by a rolling stand on which the rollers are rotatably mounted.
  • the roll stand is reciprocated in known Rollpilgeranlagen by means of a crank drive in a direction parallel to the rolling mandrel, while the rollers themselves receive a rotational movement through a fixed relative to the rolling rack, engage fixedly connected to the roller axes gears.
  • the feed of the billet over the mandrel is carried out by means of a feed tension slide, which allows a translational movement in a direction parallel to the axis of the rolling mandrel.
  • the superimposed conically calibrated rollers in the rolling stand rotate counter to the feed direction of the feed tension slide.
  • the so-called vocational mouth formed by the rollers captures the billet and the rollers press from the outside a small material shaft from the smoothing caliber of the rollers and the rolling mandrel to the intended wall thickness is stretched until the idling caliber of the rollers releases the finished tube.
  • the roll stand moves with the rolls attached thereto against the feed direction of the billet.
  • the billet is advanced by a further step onto the rolling mandrel, while the rolls with the rolling stand return to their horizontal starting position.
  • the billet undergoes a rotation about its axis to achieve a uniform shape of the finished tube.
  • the finished tubes in the prior art Due to the complex movements that run the billet or the finished tube, which consist of a superposition of rotational and translational movements, the finished tubes in the prior art have only completely left the rolling mill, before, for example by winding, in a transportable state can be brought.
  • the DD 128 573 A1 discloses a winding apparatus in a cold pilger mill which winds the exiting tube into a tube ring in unison with the rolling process.
  • a winding device for a tube made in a rolling mill with a bending device for bending the tube so that it can be spirally wound around a first axis and placed in a holding position, wherein the bending device is perpendicular to the first axis substantially the second axis is pivotally received on the holding frame, wherein the second axis coincides with the axis of symmetry of the finished outgoing from a rolling mill tube, and wherein the holding frame is configured so that it is movable in a direction substantially parallel to the second axis.
  • Such a device makes it possible to pick up the finished tube from the rolling mill and to bend it so that it can be wound up on a helical path.
  • This arrangement allows a considerable time savings in the production of steel tubes, which are dimensioned so that they can be wound up, since the expiring from the rolling mill tube can already be wound while in the same strand still in the pilgrim's mouth is introduced and transformed there.
  • the efindungssiee device allows a considerable space savings for the rolling mill as such, since in the manufacture of the tube not the entire strand must first run out of the rolling stand on its full length before it can be wound or shot.
  • the core of the winding device according to the invention is that the bending device is mounted pivotably about an axis. In this way, the bending device, the pivoting movement, which run the tube or the billet during rolling driven by the feed clamping slide, follow and the tube can be wound without twisting. Without a corresponding pivotable mounting of the bending device, there would be a twisting of the tube during winding and an associated significant loss of quality in the finished tube.
  • the bending device is driven by a motor to pivot about the second axis.
  • a motor drive largely prevents the tube from undergoing torsional stresses when it is wound up.
  • the bending device has at least three rollers rotatable about a respective axis of rotation, wherein the axes of rotation are arranged substantially parallel to the first axis and wherein at least two of the axes of rotation have a distance from the first axis different from each other, so that during operation the device is passed the tube between two rollers on a first side and a roller on another side.
  • rollers of the bending device allows a continuous bending of the tube and thus a winding about the first axis.
  • two rollers have a greater distance from the first axis than the third roller arranged between them.
  • the radius of curvature which the bending device imposes on the finished tube then depends on the difference between the distances between the first and the second roller and the third roller from the first axis.
  • the difference of the distances from the first axis can be set such that the pipe can run freely between the rolls, whereas only then is the difference between the distances of the rolls is adjusted by the first axis so that the roller, which is closer to the first axis, causes a curvature of the tube.
  • At least one of the rollers of the bending device is rotatably driven by a motor. While it is in principle also conceivable that the bending and the subsequent winding of the tube is driven by the movement of the feed tension slide of the rolling mill, a motor drive prevents at least one of the rollers of the bending device, that the tube during the winding compressive or tensile stresses in the longitudinal direction experiences.
  • the holding frame is designed so that it is movable in a direction substantially parallel to the second axis.
  • the winding device or its bending device can understand the translational movement of the tube in its longitudinal direction during rolling and the winding takes place substantially free of the influences of the forces of the feed during rolling.
  • the holding frame is driven by a motor movable.
  • the rolling mill is a cold pilger rolling mill with two rolls, wherein the take-up device is arranged in the feed direction of the pipe behind the rolls or the roll stand, on which the rolls are accommodated.
  • the rolling mill on two rollers and at least one feed chuck the feed chuck during operation of the rolling mill accommodates a billet and pushes between the rollers, wherein the feed chuck is designed to pivot and the doll receives about its longitudinal axis pivotally and wherein the rolling means a Control, which is arranged so that it synchronously pivots the feed chuck and the bending device during operation of the device.
  • the bending device is received by the second axis of the motor pivotally mounted on the holding frame. This "electronic wave" between the feed tension slide and the take-up device allows a longitudinally almost torsion-free winding of the finished tube.
  • the rolling mill has a controller which is set up so that during operation of the device in a first phase it drives at least one of the rollers of the bending device so that they pull the holding frame with the bending device on the pipe counter to the feed direction of the pipe and which fixes in a second phase at least one roller of the bending device so that the holding frame is movable with the bending device of the tube in the feed direction of the tube.
  • a controller which is set up so that during operation of the device in a first phase it drives at least one of the rollers of the bending device so that they pull the holding frame with the bending device on the pipe counter to the feed direction of the pipe and which fixes in a second phase at least one roller of the bending device so that the holding frame is movable with the bending device of the tube in the feed direction of the tube.
  • the winding process is interrupted and at least one of the rollers fixes the bending device to the wound pipe.
  • the holding frame is then moved in the direction of advance to the other end point of its translational movement, and the reeling operation of the winding device begins again.
  • Such a method is used in one embodiment for producing a coiled tube, which additionally comprises the steps of feeding a billet into a rolling mill and forming the billet into a finished tube.
  • the billet is formed by rolling, wherein the billet is pivoted during forming about its longitudinal axis, wherein the pivoting of the billet and the gift of the bending device takes place synchronously.
  • the bending device has rollers which engage with the tube, wherein in a first phase at least one of the rollers is driven so that they pull the bending device on the pipe against the feed direction of the pipe and wherein in a second phase at least one roller is fixed so that the bending device is moved by the tube in the feed direction of the tube.
