Definitions

  • the invention relates to a method for threading pipes into a drawing device according to the preamble of claim 1, and a device according to the Preamble of claim 7.
  • the object of the present invention is based on the known prior art Technology and the problems and disadvantages presented, a method and to design a device of the generic type so that the times for process-related threading process and pulling the tubes forward significantly reduced and the pulling units without lowering or only slightly Lowering the pulling speed.
  • the drive motors of the drawing chains are used to dismantle the arch controlled in their speeds depending on the pulling force.
  • a generic device is characterized by at least two Chain pulling machines arranged one behind the other with radially movable ones Drive chains as well as with pliers arranged behind each chain pulling machine for gripping the drawbar formed at the beginning of the tube, which consists of a Rest position to the side of and outside the drawing line in a working position is pivotable in the pliers between the moving chains is movable in the pulling direction.
  • the main feature of the invention is thus the pulling of the pipe starts by means of a pair of pliers through the open drive chain while running in one Combination of at least two chain pulling machines arranged one behind the other.
  • a free space is preferably provided between two adjacent drawing units
  • Forming a sheet deflecting the drawn material from the straight line is provided, wherein Sensors for detecting the size of the sheet are arranged with the Drive motors for the drive chains are connected in terms of control.
  • the Bows are used to compensate for the speed differences between the successive drawing units, the size of the deflecting Arc is a measure of the speed difference.
  • the sensors for detecting the size of the sheet can be, for example, as Diode row barriers can be formed, the a signal for processing to a Submit computer that controls the drive motors for the drive chains accordingly.
  • the process of Threading a pipe start into three consecutively arranged as Chain drawing machines trained drawing units shown.
  • the Chain drawing machines are designated with 1,2 and 3, which are upper drive chains correspondingly with 1a, 2a and 3a and the lower drive chains with 1b, 2b and 3b designated.
