Definitions

  • the invention relates to a device for producing pipes by helically winding a preferably corrugated band with a winding device made of freely rotatable support rollers arranged in a circle on the outer circumference of the pipe to be wound, their axes of rotation parallel to one another and to the longitudinal axis of the pipe to be wound on a common carrier plate are arranged, with two drivable feed rollers arranged at the entry point of the belt into the winding device, acting on the two broad sides of the belt, and with two drivable drive rollers arranged at a distance in front of the pair of entry rollers, also acting on the broad sides of the belt, the carrier plate being such is arranged that the center axis running through the center of the circle formed by the support rollers and parallel to the axes of rotation of the support rollers is the plane determined by the axes of rotation of the inlet rollers in the pitch angle of the R to be wound ear cutting to
  • a known device of this type has the disadvantage of only a very low production speed
  • the object of the present invention is to develop a device of the type mentioned at the outset such that pipes of any length can be produced in a simple manner at high working speed.
  • the object is achieved in that the peripheral speed of the inner run-in roller arranged inside the winding device is lower than the peripheral speed of the outer run-in roller arranged outside the winding device.
  • the inner infeed roller advantageously has a smaller diameter than the outer infeed roller.
  • the Slip of the inner feed roller with respect to the outer feed roller is preferably 0.2 to 0.5 mm per revolution of the inner feed roller.
  • the carrier plate is arranged such that the central axis intersects the plane determined by the axes of rotation of the inlet rollers in the intersection line of this plane with the plane running through the center of the inlet rollers and perpendicular to the axes of rotation of the inlet rollers.
  • the carrier plate preferably has an abutment surface which is inclined at an angle of 90 ° to the central axis and which is inclined by the pitch angle of the tube to be wound and which bears on a holding surface perpendicular to the axes of rotation of the inlet rollers, and is the carrier plate in the winding direction of the band around the central axis rotated arranged that the line of intersection of the plane of the contact surface with a plane perpendicular to the central axis intersects the plane extending through the axes of rotation of the feed rollers at an acute cutting angle.
  • the cutting angle is preferably 0.5 to 1.5 °.
  • the carrier plate is advantageously of annular design.
  • the carrier plate is preferably releasably attached to the holding surface.
  • a belt guide is arranged between the feed rollers and the drive rollers.
  • the peripheral speed of the drive rollers is advantageously greater than the peripheral speed of the outer feed roller.
  • the slip of the drive rollers to the outer feed roller is preferably 0.2 to 0.5 mm per revolution of the drive rollers.
  • a bending roller is preferably arranged between the belt guide and the inlet rollers, said bending roller projecting beyond the connecting line between the inlet point and the belt guide in the direction of the central axis of the winding device.
  • the bending roller can preferably be rotated about an axis of rotation parallel to the axes of rotation of the infeed roller.
  • the bending roller is advantageously displaceable and fixable in the direction of the central axis.
  • a holder 1 has a holding surface 2, on which a winding device 3 is arranged.
  • the winding device 3 has an annular support plate 4, which carries annularly arranged, freely rotatable support rollers 5 on the outer circumference of the tube to be wound, the axes of rotation 6 of which are parallel to one another.
  • the central axis 7 running through the center M of the circle formed by the axes of rotation 6 of the support rollers 5 and parallel to the axes of rotation 6 of the support rollers is equal to the central longitudinal axis of the tube to be wound.
  • two entry rollers 9 and 10 are arranged which can be driven and which act on the two broad sides of the strip.
  • the inner infeed roller 9 is arranged inside the winding device 3, while the outer infeed roller 10 is arranged outside the winding device.
  • the feed rollers can be rotated about axes of rotation 11 perpendicular to the holding surface 2 and can be driven by a drive device, not shown.
  • the inner feed roller 9 has a smaller peripheral speed than the outer feed roller 10.
  • the carrier plate 4 has an abutment surface 12 which extends to the central axis 7 at an angle of 90 ° by the pitch angle ⁇ of the pipe to be wound and which bears on the holding surface 2, so that the axes of rotation 6 of the Support rollers 5 or the central axis 7 intersect the plane designated by 13 in the pitch angle, determined by the axes of rotation 11 of the inlet rollers 9 and 10.
  • the carrier plate 4 is arranged on the holding surface 2 such that the central axis 7, the plane determined by the axes of rotation 11 of the inlet rollers 9, 10, designated by 13 in the line of intersection of this plane with that through the center of the inlet rollers 9 and 10, perpendicular to the axes of rotation 11 of the infeed rollers run, 14 designated plane intersects.
  • the band 8 to be wound runs symmetrically to this plane, which is designated by 14.
  • the carrier plate 4 is arranged rotated about the central axis 7 in the winding direction indicated by the arrow 15 in such a way that the line of intersection of the contact surface 12 designated with 16 has a plane perpendicular to the central axis 7 (in FIG. 2, for example the level denoted by 17) by intersects the axes of rotation 11 of the inlet rollers 9 and 10, designated 13 at an acute cutting angle ⁇ .
  • two drive rollers 18 are arranged on the holder 1, which also act on the broad sides of the belt 8.
  • the drivable drive rollers 18 are rotatable about axes of rotation 19 perpendicular to the holding surface 2, the plane running through the axes of rotation 19, designated by 20, running parallel to the plane designated by 13 through the axes of rotation 11 of the feed rollers 9 and 10.
  • a belt guide 21 is arranged between the drive rollers 18 and inlet rollers 9 and 10. The peripheral speed of the drive rollers 18 is greater than the peripheral speed of the outer feed roller 10.
  • a bending roller 22 which can be rotated about an axis of rotation 23 perpendicular to the contact surface 2 and is arranged on the holder so as to be displaceable and fixable in the direction of the central axis 7.
  • the bending roller 22 is set such that it projects beyond the connecting line between the entry point and the belt guide 21 in the direction of the central axis 7, as shown in FIG. 1.
  • the band In the manufacture of a tube by helically winding the band 8, the band is first fed in the direction of the arrow labeled 24 to the drive rollers 18, which feed it through the band guide 21 and via the bending roller 22 to the inlet roller pair 9 and 10 of the winding device 3.
  • the band 8 In the winding device, the band 8 is wound helically to form a tube, the feed rollers 9 and 10 establishing the connection of the incoming band with the tube that has already been wound.
  • the wound tube is withdrawn from the winding device 3 in the direction of the arrow labeled 25.
  • the slip between the two inlet rollers or between the outer inlet roller and the drive rollers is 0.2 to 0.5 mm per revolution of the inner inlet roller or the drive rollers.
  • a value of 0.5 to 1.5 0 was found to be favorable for the cutting angle f.
  • the ring-shaped carrier plate 4 is releasably attached to the holding surface 2 of the holder 1, so that another winding device with the corresponding diameter can be fastened to the holder 1 in order to produce a tube with a different diameter.
  • the fact that the inner feed roller 9 has a very small diameter not only makes bending work easier, but it is also possible to produce tubes with a very small diameter.
