Definitions

  • a machine for producing a large diameter tube from strip sheet metal material comprises a frame, a profiling station and a folding station.
  • the frame comprises lower and upper rings which are connected to one another by vertical posts.
  • the vertical posts carry supporting rollers, which are arranged in the form of a helix with a vertical axis.
  • strip sheet metal is fed to the profiling station where it is bent into a curve having a diameter equal to the required diameter of the tube and profiled so that subsequent turns can be slotted together.
  • the strip is then fed to the folding station, which locks adjacent turns together.
  • the tube being formed is supported by the supporting rollers by a flange formed by the folding operation.
  • This invention relates to a machine for the production of a large-diameter tube, more particularly a silo, from a sheet-metal strip coiled on a feed reel, comprising a profiling station, which has a path which is constructed to match the bending of the tube wall and extends in offset relationship to the cylinder defined by the tube, and comprising a folding station which is disposed substantially on one side, more particularly on the outside, of the wall of the tube under production, the profiling station and filing station being associated with a frame.
  • the object of the invention is to provide a machine with which a vertical tube, more particularly a silo, can be readily produced from the ground up, those parts of the machine which are situated inside the tube being adapted to be removed therefrom after the tube or silo has been produced and before the same has been lowered on to the ground.
  • a machine for the production of a tube from a sheetmetal strip coiled on a feed reel comprising a frame of annular construction which is adapted to be erected on the ground, supporting rollers carried by the frame and disposed on a helix at a distance from the bottom end of the frame, and intended to support the tube at a fold therein, a profiling station associated with the frame, adapted to be erected on the ground and having a path which extends next to the helix defined by the supporting rollers in offset relation to the tube, so as to match the bending of the tube wall and a folding station associated with the frame and, which is also disposed on the ground so as to be substantially on one side of the wall of a tube when produced the folding station having a path which coincides with the helix defined by the supporting rollers.
  • the steps of the method required for producing the tube from a sheet metal strip can be carried out from the ground irrespective of the height of the tube or silo, the tube or. silo helix being continued in the upward direction on the supporting rollers during the production operation, in accordance with the strip feed.
  • the bottom end of the finished tube resting on the supporting rollers may have a distance from the ground such that the parts of the machine resting on the ground inside the tube can be removed from the latter before it is lowered to the ground, for which purpose the tube is rotated helically in the opposite direction.
  • the supporting rollers support the tube until it rests on the ground.
  • the supporting roller is mounted on a pivoting arm which is pivotable about a substantially horizontal axis and which is secured against excessive deflection towards the interior of the frame by means of a strap.
  • the supporting rollers can adjust to small diameter variations of the tube or silo and, by their inclined position or by their distance from a reference point, indicate whether the tube is below size or oversize in the region of the frame. If the machine has a separate infinitely controllable drive motor for each of the profiling and folding stations, then advantageously two limit switches for controlling one of the motors are provided on the annular frame in radially spaced relationship between the profiling station and the folding station, the inner switch being used to increase the :speed and the outer switch to reduce the speed of the controlled motor.
  • An equalizing mechanism may be associated with the folding station to adjust the tube to the required nominal diameter if the latter is exceeded or not attained.
  • At least one of the supporting rollers may be provided with a drive comprising an infinitely controllable motor, so that there may be more than two motors to raise the silo helically. This is advantageous particularly in the production of very high and/or large-diameter silos. Silos of a diameter of more than 20 m and a height of more than 20 m may be built by means of the machine.
