Definitions

  • the present invention relates to a resolving device for spinning machines, in particular open-end spinning machines, which is equipped with a clothing wire or a ring for singling fibers of a fed sliver.
  • the invention relates to a method for producing such a dissolving device.
  • the driving elements fastened on the circumference of the driving elements strike the fibers to be separated at high speed and accelerate them. This strong abrasive forces act on the corresponding components of the devices.
  • One way to design the driver elements is to equip an opening roller with a plurality of needle elements, the fibers in each round, for example remove a sliver and take with you.
  • Another technical solution provides to design the driver in the form of saw teeth.
  • clothing wires have proved to be useful, which consist of a long metal wire from which the sawtooth contour is punched out. The clothing wire thus produced is then attached to the opening roller by means of a helical groove.
  • Another solution provides to form the opening rollers in one piece.
  • sawtooth geometries in a one-piece workpiece for example by turning and grinding, formed.
  • the object of the invention is therefore to provide a resolving device and a method for their production, which allow for easier processing with improved service life with a particularly uniform quality of the products produced and beyond which are particularly well tuned to the products to be processed.
  • the object is achieved by a resolving device which is characterized in that, in particular, the clothing wire is pre-bent according to the geometry of a carrier ring or the clothing ring has the desired finished part geometry.
  • the respective workpiece surfaces have a construction of at least two layers, wherein an outer layer is a fabric layer which consists wholly or partly of particularly hard hard material shares and on an underlying Substrate layer rests.
  • a higher proportion of hard material leads to a particularly resistant, but also to the fibers to be processed harder surface and vice versa.
  • the type of incorporated in the outer layer of hard materials can be varied as needed. This vote can be adjusted depending on the needs of the user, in particular its spinning technology requirements.
  • the outer layer it has proved to be advantageous to apply this by means of a CVD, PVD or plasma CVD method. All methods have in common that they ensure a particularly uniform layer thickness. In particular, however, in the case of the PVD and the plasma CVD method, the application of the outer layer can be carried out at particularly low temperatures. This means that only very small changes in the microstructures of the substrate materials occur during the implementation of the method.
  • the hard material components of the outer layer optionally comprise one or more of the compounds CrN, CN, CrCN, TiN, TiCN, TiAlN, AlTiN, ZrN, NbN, WC or the properties of diamond-like carbon steel Own (DLC). Any of these compounds or materials may be used alone or in combination with one or more of the others. Thus, if necessary, their properties can be combined with each other in an advantageous manner.
  • the application of the outer layer is done in an advantageous embodiment of the invention in the form that the outer layer is formed as a one-component layer.
  • the outer layer can be applied directly to the substrate layer with a freely selectable hard material component or one or more types of hard materials.
  • the quantity and the quality of the layer containing outer hard materials can be adapted particularly well to the respective requirements.
  • the outer layer is formed as a multi-layer.
  • the outer layer is constructed from a plurality of layers.
  • it has proven to be particularly advantageous to have alternating arrangements of relatively elastic layers with particularly resistant and hard layers.
  • the structure corresponds to a kind of sandwich construction in this embodiment.
  • the alternating arrangement of elastic and hard layers has the advantage that on the one hand a particularly resistant surface is created and at the same time the flexibility of the component is largely retained by the elastic layers. This will increase the risk of spalling or other detachments of the hard surface significantly reduced.
  • the outer layer contains dispersed dissolved hard material particles with sizes in the nanometer range. So-called nanoparticles are firmly anchored in the outer layer because of their particularly small geometrical dimensions and therefore do not accidentally come off during operation. Due to their hardness, they can significantly increase the wear resistance of the component and are at the same time arranged in an elastic basic body.
  • an advantageous embodiment of the invention provides that the outer layer is precipitation hardened.
  • Precipitation hardening methods are already known in the art, but in the context of the present invention offer a possibility to further improve the positive properties of the devices according to the invention.
  • the outer layer is even more resistant to wear after precipitation hardening.
  • the substrate layer in particular the surface of the wear-prone sections of the opening device, is preferably tempered at the application temperatures of the outer layer prior to the application of the outer layer.
  • the tempering is therefore preferably carried out at the same temperature which also prevails during the subsequent application of the outer layer.
  • the PVD and plasma CVD processes offer the advantage of particularly low application temperatures.
  • Layer thicknesses of the outer layer which are between 2 and 8 ⁇ m have proven particularly advantageous.
  • the applied outer layers are, on the one hand, able to protect the underlying substrate layers to a sufficient extent. At the same time, however, it is ensured that the layer thicknesses are not so great that, for example, flaking or other detachments occur.
  • a carrier layer is applied between the outer layer and the substrate layer.
  • This carrier layer has two functions. The first function is to create a secure bond between the substrate layer and the overlying outer layer. The second function of the carrier layer is based on the fact that it compensates for unevenness and irregularities in the substrate layer and thus creates a particularly uniform contact surface for the outer layer.
  • a carrier layer is used which is a chemically applied nickel-phosphorus layer. Chemically applied layers, in particular of the aforementioned type, have the advantage that they have extremely uniform layer thicknesses.
  • the outer layer is deburred and or polished.
  • This can be done in principle by means of all known Entgratungssch and methods, but in particular chemical or electrochemical deburring has been found to be very suitable.
  • the so-processed particularly smooth surfaces of the clothing wires or clothing rings treat the fibers to be processed extremely gently and consequently produce a particularly low dust formation during the spinning process.
  • it also makes sense to polish the outer layer. This can be done for example by a relative movement between the inventively designed component and a polishing fluid.
  • the polishing fluid leads to particles of hard material which smooth the surface of the component by repeated impingement.
  • hard particles for example, diamond particles, corundum, silicon carbide or silicon nitride serve, all of which have a particularly high hardness. If, for example, a dissolving device is left to rotate for a long time in such a polishing fluid, a particularly smooth and resistant surface is obtained.
  • the carrier layer is a layer applied by means of a galvanic process. It has proven to be particularly advantageous if this layer is a galvanically applied nickel layer. Electroplated layers are particularly inexpensive to manufacture and can be applied with sufficient uniformity.
  • the carrier layer is an additional hard material layer.
  • this hard material layer designed as a carrier layer can be optimized, for example, by suitable choice of material with regard to particularly great elasticity and excellent adhesion mediation.
  • the layer thickness of the carrier layer is advantageously between 3 and 10 microns and is thus slightly stronger than the layer thickness of the outer layer. In this case, as the layer thickness of the carrier layer increases, its ability to compensate for unevennesses on the substrate layer increases.
  • the carrier layer at temperatures of 320 ° C to 370 ° C, in particular of 350 ° C is annealed.
  • a chemically applied nickel-phosphorus layer such as a tempering already in the support layer, a hardness of 900-1000 HV can be achieved.
  • This is a particularly resistant layer on which an outer layer applied to it finds a particularly good hold and on the other hand finds a particularly solid foundation.
  • the respective workpiece surfaces are provided with an at least two-layered structure, wherein an outer layer is applied to an underlying substrate layer which is a hard material layer and which consists wholly or partly of particularly hard hard material constituents.
  • an outer layer is applied to an underlying substrate layer which is a hard material layer and which consists wholly or partly of particularly hard hard material constituents.
  • FIG. 1 shows a side view of an opening roller 1 according to the invention.
  • a clothing wire 3 is arranged on a support ring 2 on its radially outer side. This is arranged with a plurality of turns and with a constant pitch in the axial direction on the support ring 2.
  • the opening roller 1 according to the invention rotates in the normal operating state at high speed about a rotation axis 4.
  • the fibers in the radial direction to the opening roller 1, for example in the form of a sliver, are detected upon reaching driving elements of the clothing wire 3 and dissolved out of the dressing.
  • the driver elements are subject to a particularly high mechanical wear due to the high speed and the continuous operation.
  • FIG. 2 shows a section of a clothing wire 3 in a side view.
  • the clothing wire 3 has a foot region 5 which serves for attachment to the carrier ring 2.
  • the use of foot profiles which are tuned to grooves in the support ring 2 have proven in practice for fastening the clothing wire 3.
  • the driver elements which are formed in the present case in the form of teeth 6.
  • the teeth 6 have on one side a shallow rising leg 7 and on the opposite side a steeper sloping leg 8.
  • a tip 8 formed between the two legs is inclined towards one side, which defines a direction of rotation 9 of the opening roller 1.
  • FIG. 3 schematically shows the helical winding of the clothing wire 3, which is pre-bent with a predetermined diameter d.
  • the diameter d corresponds to either exactly or at least approximately the outer diameter of the support ring 2 and the diameter of the groove bottom of the associated groove on the support ring 2.
  • FIG 4 one half of an opening roller 1 according to the invention is shown in an axial sectional view.
  • the body of the carrier ring 2 is characterized by a coarse hatching on the cut surface.
  • a spiral groove 10 are incorporated, in which the marked with a fine hatching Garniturdraht 3 is inserted.
  • FIG. 5 shows another possible embodiment of an opening roller 1.
  • the opening roller is equipped with a fitting ring 11.
  • the production of such Gamiturrings 11 can be done for example by machining on a lathe, followed by a subsequent incorporation of the tooth contours by grinding processing in the transverse direction to the previously machined toothed webs.
  • FIG. 6 shows an inventive construction of a first preferred embodiment of the invention.
  • the upper side represents the outside of the workpiece and the lower side shows the area in the direction of the workpiece interior.
  • the material of the clothing wire 3 or the clothing ring 11, hereinafter referred to as the substrate 12, represents the lower substrate layer.
  • an outer layer 13 is applied, which preferably has a layer thickness of 2-8 microns.
  • the application of the outer layer 13 by means of a PVD, CVD or plasma CVD method.
  • PVD and plasma CVD methods are used, since they can be carried out at significantly lower coating temperatures than the CVD method.
  • profound thermally induced microstructural changes in the substrate 12 are avoided during the layer application.
  • the substrate 12 has been subjected to an annealing process prior to the application of the outer layer 13.
  • the temperature of the heat treatment preferably corresponds to that temperature at which the outer layer 13 is applied. In this way, the otherwise occurring during application of the outer layer 13 structural transformations are anticipated.
  • the outer layer 13 is formed in this embodiment as a single-layer. Contained in this outer layer 13 are hard material components which can be adapted both in their quality and in their quantity to the respective requirements.
  • FIG. 7 shows the schematic structure of the surface structure of another advantageous embodiment of the invention.
  • the substrate 12 is shown, which has the same properties as the substrate 12 previously described in FIG. 6.
  • the overlying outer layer 13 in this embodiment has a different construction in that I am in this case a multilayer.
  • the outer layer in turn has a layer thickness of preferably 2-8 microns.
  • This sandwich of layers allows different materials and their advantageous properties to combine with each other, which at the same time the use of particularly elastic and highly resistant materials within the outer layer 13 is possible.
  • the first layer 14 shown without hatching may be a particularly elastic layer which firmly bonds an overlying particularly resistant second layer 15 to the substrate 12 and the underlying layers, respectively. If a component constructed in this way undergoes deformations, the residual stresses arising in the hard layers 15 are significantly lower than would be the case with a hard material layer extending homogeneously over the entire layer thickness. As a result, flaking either no longer occurs or at least only under extreme conditions.
  • FIG. 8 shows a further advantageous embodiment, in which again the substrate 12 has been kept unchanged.
  • the outer layer 13 which, however, this time contains the disperse dissolved nanometer-sized hard material particles 13a.
  • the size ratios shown in FIG. 8, in particular those of the hard material particles 13a do not reflect the real size ratios.
  • the storage of dissolved hard particles 13a increases the wear resistance of the outer layer 13 considerably.
  • the layer thickness of the outer layer 13 was carried out in the range of 2-8 microns, so that the layer on the one hand provides sufficient wear reserves and at the same time no chipping due to excessive internal stresses occur.
  • FIG 9 another advantageous embodiment of the invention is shown in which between the known from Figure 6 outer layer 13 and the substrate 12 also known from this figure, an additional support layer 16 is arranged, which preferably has a layer thickness of 3-10 microns ,
  • the carrier layer 16 has two tasks.
  • the first object is to improve the adhesion between the outer layer 13 and the substrate 12.
  • the second object is to compensate for any unevenness present on the surface of the substrate 12 and to provide a particularly well-prepared bearing surface for the outer layer 13.
  • the carrier layer 16 is optionally applied by a chemical process or a galvanic process.
  • the surface created in this way is particularly clean and free of disturbances and is also particularly easy to reproduce in large-scale use. Furthermore, a particularly high hardness can already be achieved here with corresponding carrier layers. If a nickel-phosphorus layer is used as the carrier layer, its surface can reach hardness values of approximately 1000 HV by annealing at preferably 350 ° C. This creates a particularly advantageous basis for the later applied thereto outer layer 13, which is both very hard and even and also provides good adhesion.
  • FIGS. 10 and 11 once again illustrate the substrate 12 and the outer layer 13, as already described in FIGS. 7 and 8.
  • the carrier layers 16 according to the invention are respectively arranged between the outer layer 13 and the substrate 12.
  • the present invention is not limited to the illustrated embodiments. Rather, numerous modifications of the invention within the scope of the claims are possible.
  • suitable materials and compounds with other properties can be used instead of the hard material components mentioned in the subclaims.
  • the layer structures described for the opening device can also be used on other components of textile machines that are subject to wear, such as, for example, thread take-off nozzles or rotors.
