Definitions

  • the invention relates to a method for producing opening roller rings, in particular for open-end spinning machines, according to the features of the preamble of claim 1.
  • opening roller rings by winding a piece of pipe that already has the length of the opening roller ring with a sawtooth wire and attaching it to the pipe section at its beginning and end. This manufacturing method cannot keep up with the increasing demands on the concentricity of opening rollers.
  • opening roller rings including their clothing are often milled from the solid, which is complex and expensive.
  • the invention is therefore based on the object of making available a method of the type mentioned at the outset which, while maintaining the required accuracies, enables simple and cost-effective production of opening roller rings.
  • the beginning and end of the sawtooth wire wound on the opening roller ring are fastened to it again. It is important, however, that the start and end of the short sawtooth wire do not coincide with the start and end of the long sawtooth wire wound on the entire tube. In addition to the high accuracy of the opening roller rings produced in this way, they can also be produced very economically, since not every opening roller ring has to be wound separately.
  • the wound tube is plasma-coated before being separated into the opening roller rings. This has the advantage that not every opening roller ring has to be plasma-coated on its own and that the opening roller ring is nevertheless completely coated.
  • the sawtooth wire can be particularly easily attached to the tube in the Einstechnuten in the electron steel welding process.
  • a particularly permanent fastening can be achieved according to the feature of claim 4 in that the electron beam is guided in a zigzag pattern around the tube around the groove base of the Eintstechnut. Sawtooth wires with narrow feet can also be securely and permanently attached to the tube.
  • the puncture can also be produced by milling, it is preferred according to claim 5 to grind away the teeth in the puncture by means of a plunge grinding slide. This allows the groove base of the insertion can be processed immediately on the required surface, whereby it does no harm if the sawtooth wire is already hardened from being pulled onto the pipe.
  • the wound tube is cut by a laser cutting steel into the opening roller rings, this has the advantage that the opening roller rings then no longer have to be reworked.
  • the laser cutting beam cuts the sawtooth wire feet previously welded onto the tube in one step and the tube.
  • the laser separating beam can be guided exactly through the center of the Einstechnut. This creates the same clamping points for the opening roller rings on both sides.
  • the sawtooth wire is wound onto the tube in such a way that the feet of adjacent sawtooth wire turns abut one another. Since the sawtooth wire naturally has a changing moment of resistance to bending over its length, the tooth base wraps around the tube in the form of a polygon when the tube is wound. In the tooth root area between two teeth, the base of the sawtooth wire does not rest on the surface of the tube. If these places were freely accessible, particularly fine, thin fibers could penetrate and jam here, which would impair the work result of the opening roller. However, when the feet of adjacent sawtooth wire turns meet, the fibers are denied access to these locations. The fibers can therefore not get caught under the base of the sawtooth wire.
  • a tube 1 is shown in a partially sectioned side view.
  • the length of the tube 1 is several times greater than the length of the opening roller rings 2 to be produced (cf. FIG. 5).
  • a sawtooth wire 3 is wound onto the tube 1, the beginning 4 and end 5 of which are fastened to the tube 1 by means of screws 6.
  • Such a sawtooth wire 3 is shown in FIG. 6. It can be seen that the sawtooth wire 3 has an L-shaped profile in cross section, the vertical L-leg representing the teeth 7, while the horizontal L-leg forms the foot 8 of the sawtooth wire 3. It can be clearly seen from the illustration in FIG. 6 that the foot 8 is many times wider than the cross section of the teeth 7.
  • the sawtooth wire 3 is wound onto the tube 1 in such a way that the feet 8 of two adjacent sawtooth wire turns abut one another without a gap.
  • the tube 1 looks as shown in FIG. 1.
  • the teeth 7 of the sawtooth wire 3 are then ground away at intervals a by means of a plunge-cut grinding wheel, not shown, so that circumferential plunge grooves 9 are formed. Only the foot 8 of the sawtooth wire 3 remains in the area of the insertion grooves 9.
  • the width of the groove 9 is approximately 1 1/2 times the width of the base 8 of a sawtooth wire 3.
  • the first groove 9 is placed directly next to one of the fastening screws 6, after which a further groove is then inserted at intervals a follow 9.
  • the distances a correspond to the later width of an opening roller ring 2.
  • the base 8 of the sawtooth wire 3 is fastened to the tube 1 in the insertion grooves 9 using the electron beam welding method.
  • the electron beam is guided along a zigzag line 10, so that the foot 8 of two adjacent sawtooth wire turns 12 and 13 is captured by the electron beam.
  • the tube 1 wound with the sawtooth wire 3 can then be plasma-coated as a whole, which is known per se.
  • a plasma layer with the finest grain and subsequent weak impregnation is preferred.
  • the dimension a it must be taken into account that the separation of the opening roller rings with a laser beam also means that material is lost, so that the dimension a must be slightly larger than the desired final length of an opening roller ring.
  • the initial turn 12 and the end turn 13 of the sawtooth wire 3 have no teeth 7, but only the foot 8, which is attached to the tubular body by electron beam welding.
  • the sawtooth wire can also be attached by laser welding. It is also conceivable to secure the sawtooth wire in the insertion grooves by means of electrical spot welding on the pipe 1, although a counterhold must then be provided inside the pipe.
  • the opening of the opening roller rings 2 from the tube 1 can also be done mechanically by means of cutting discs or the like.
