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 DE 198 22 265 A1 provides a two-layer structure of a nickel-diamond coating on a spinning rotor, wherein in an inner support layer larger diamond grains are embedded and smaller grains in an outer working layer. Due to the fine grain of the working layer a good sliding quality for the fibers should be achieved, whereby the life of the coating should be increased.
  • the US 4,358,922 provides a two-layered construction with an inner layer in which hard-material grains are embedded, and an outer layer without Hartstoffkörner. The outer layer should cover the hard grains of the inner layer and provide a smooth surface.
  • the coating is preferably designed as a nickel-phosphor coating, embedded in the inner layer of diamond grains.
  • the US 6,293,083 B1 describes a multilayer structure of a nickel-diamond layer, wherein between two layers containing hard material grains, in each case a layer is introduced, which is free of hard material Körnem. The wear resistance of the coating should thereby be increased even with damage to the outer layer.
  • the DE 101 09 523 A1 describes a multilayer structure of a hard material coating on a component for cutting or forming machining.
  • the layers are titanium-based and deposited by a PVD, CVD or plasma DVD process. Between two layers of the hard coating, in each case an intermediate layer, preferably of cobalt, which reduces stresses in the coating and should reduce the risk of spalling is disposed. As a result, comparatively thick layers with good adhesion can be applied.
  • the DE 41 01 680 A1 shows an opening roller, the set is provided with a two-layer structure, wherein as the outer layer, a wear-resistant nitride layer is applied in a PVD process.
  • the inner first layer is also applied as a wear-resistant layer, preferably as a carbide layer, with a rough surface structure.
  • the layer thickness is therefore between 15 microns to 30 microns.
  • the object of the invention is therefore to provide a resolving device and a method for their preparation, which allow for easier processing with improved service life with a particularly uniform quality of th PRODER th products 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 in accordance with the geometry of a carrier ring or the clothing ring has the desired finished part geometry.
  • the respective workpiece surfaces have an at least two-layer structure, wherein an outer Layer is a fabric layer which consists wholly or partly of particularly hard hard constituents and rests on an underlying substrate layer.
  • an outer Layer is a fabric layer which consists wholly or partly of particularly hard hard constituents and rests on an underlying substrate layer.
  • 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.
  • particularly hard and brittle outer layers may be applied to the wear-loaded surfaces of the disintegrators as needed, which would otherwise often result in chipping when post-formed.
  • the properties of the surface can be varied by varying the hard material proportions within the outer layer.
  • 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 hard material components of the outer layer optionally have one or more of the compounds CrN, CN, CrCN, TiN, TiCN, TiAIN, 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.
  • As a particularly advantageous has an alternating arrangement of relatively elastic layers with particularly resistant and hard layers proved.
  • 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 significantly reduces the risk of chipping or other detachment of the hard surface.
  • 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 annealed at the application temperatures of the outer layer prior to the application of the outer layer is.
  • annealing a structural transformation occurring under certain circumstances during application of the outer layer is already anticipated.
  • 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.
  • 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 for a long time in such a polishing fluid rotate, you get a particularly smooth and resistant surface.
  • the carrier layer is a layer applied by means of a chemical process.
  • 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 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 is tempered at temperatures of 320 ° C to 370 ° C, in particular of 350 ° C.
  • 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 fractions.
  • 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 fractions.
