Definitions

  • the invention relates to a wire brake and tensioning device, in particular for wire drains, which includes the wire to be braked and tensioned.
  • Wire drains of the type mentioned above are used in conjunction with winding machines and essentially have the task of maintaining a constant tension of the wire from the wire reel to be unwound to the spool on the winding machine. Furthermore, these devices are intended to prevent the wire from being unwound further from the coil in an uncontrolled manner due to the moment of inertia of the rotating parts when the wire tension decreases.
  • the pretension given to the wire by the tensioning device must not exceed a certain value, which must be matched to the respective wire thickness, in order to ensure that there is no stretching of the wire which can lead to cracks in the insulating layer.
  • a certain value which must be matched to the respective wire thickness
  • the most commonly processed wire thicknesses of approx. 0.05 'to 2.0 mm require maximum tension of 24 to 15 kg.
  • this area cannot be covered, so that for the processing of wires from 0.04 to 0.45 mm, for wires from 0.17 to 0.90 mm and for those from 0.25 to 2.0 mm separate unwinding and braking and tensioning devices must be used.
  • the invention is based on the object of designing a wire brake and tensioning device of the type mentioned at the outset in such a way that it can be used for all practically occurring wire diameters and is also inexpensive to manufacture.
  • the device has at least one flexible brake band which is arranged essentially parallel to the wire and the ends of which are fastened in holders of the device, at least one of which is displaceable in the longitudinal direction of the wire and rotatable about the latter.
  • the brake or tension band can e.g. consist of textile or plastic fabrics.
  • the brake band is wound and tensioned around the wire by rotating and moving one of the brackets.
  • the braking effect transferred to the wire is adjusted depending on the number of times the wire is wrapped and the tension of the belt.
  • a device according to the invention can be used equally for round wires as well as for those with square, rectangular or polygonal cross sections.
  • the device consists of a cylinder, the one opening tion is closed by a plate provided with a centrally arranged hole and in the other opening a nut provided with a centrally arranged hole is screwed, wherein in the plate and in the mother several symmetrical to the wire fastening points are provided for the brake bands.
  • Two brake bands are advantageously used, which are fastened in the form of an endless band in the device.
  • the wire brake and tensioning device 1 shown in the figures consists of a cylinder 2, which is closed at one end by a plate 3.
  • the plate 3 is welded to the cylinder 2.
  • the other side of the cylinder 3 has an internal thread 4 and is closed with a nut 5.
  • Both the plate 3 and the nut 5 have a central bore 6 and 7, in which guide tubes 8, 9 are inserted, which are made of a soft material and are intended to prevent the insulation layer of the wire 10 from being damaged.
  • the plate 3 and also the nut 1 each have two further bores 11 and 12 through which a brake band 13 shown in broken lines is guided. Furthermore, the mother as well as the plate opposite cutouts 14 and 15, Brake band attached is.
  • the fastening and guiding of the brake band can be seen in FIGS. 1 and 2.
  • To insert the brake band it is first clamped behind the plate 3 and then pulled through the cutouts 14 and inserted through the bores 11 into the interior of the device 1 and then through the bores 12 to the outside and then through the cutouts 14 behind the nut 5 connected with each other.
  • the brake band is thus self-contained.
  • the cylinder 1 also has a fastening bolt 16 for its fastening e.g. on a wire drain. Furthermore, two viewing windows 17 are cut out in the cylinder 2, which facilitate the threading of the wire 10 into the device 1.
  • the device according to the invention is suitable for both the smallest and the largest occurring wire diameters. Furthermore, the braking force is continuously adjustable over a wide range.
  • the device according to the invention is characterized by an uncomplicated structure and, compared to the known braking and tensioning devices, is extremely inexpensive to manufacture.
