Definitions
- the present invention relates to a method for applying a surface lubricant carrier layer to a material to be subsequently deformed in a cold forming process, in particular to a wire material to be deformed in the drawing method, a solid lubricant subsequently being able to be applied to the lubricant carrier layer.
- the invention also relates to a special device for carrying out this method and a novel substance for use in the method according to the invention, i.e. to form the lubricant carrier layer.
- this lubricant carrier layer can also be formed by so-called phosphating (see Lueger, volume 8, page 546).
- the lubricant carrier fills the valleys of the rough material surface (underground filler) and thus serves to anchor an actual separating lubricant to be applied subsequently.
- wire drawing is usually a solid lubricant based on soap, especially a metal soap, such as lithium stearate (so-called "dry pulling", see Lueger, volume 8, page 124).
- the wire is drawn through a carbide or diamond drawing nozzle and its cross-section is reduced and elongated (plastic, essentially non-cutting deformation).
- the drawing nozzle is preceded by a container in which the solid lubricant is located Is in powder form, and the wire passes through this lubricating powder and constantly takes particles with it, which then form a "lubricating film" in the drawing nozzle.
- the present invention is therefore based on the object of reducing the outlay for applying a lubricant carrier layer and preferably also for the required material pretreatment, but at the same time ensuring an at least consistently good separating lubrication during the subsequent cold-forming process .
- productivity should even be increased by improved lubrication properties.
- this is first achieved by means of a new type of dry coating process, with an equally new type of dry carrier material, ie a carrier material which is in the "dry phase” and not dissolved in water or another solvent, in the cold state (approximately usual room temperature) is applied.
- This preferably powdery and / or granular dry carrier material is preferably applied mechanically by pressing or pressing.
- the complex wet chemical processes are therefore unnecessary.
- the dry carrier material according to the invention consists of a preferably powder and / or granular dry formulation which - as a "reactive component" - contains a soap portion, in particular a metal soap ; and preferably - as "non-reactive component” - contains certain fillers.
- non-reactive component fillers
- the preferably contained “non-reactive component” brings about good adhesion to the material surface by filling in the unevenness due to the small particle size of the fillers and thus acting as a primer or adhesion promoter.
- the "reactive component” can - depending on the amount of its content in the dry substance - already provide sufficient lubrication for the subsequent forming process (eg wire drawing), so that a further lubricant may possibly be entirely unnecessary.
- an "actual lubricant” is preferably added, which can be a known solid lubricant with metal soap components.
- the soap components of the dry carrier material according to the invention and of the dry lubricant then react with one another, in particular by pH compensation, in such a way that the dry lubricant adheres well to the material via the lubricant carrier layer produced according to the invention.
- a special device for applying the new dry carrier material as a lubricant carrier layer has a “dry coating container” for holding a large number of loose pressure bodies and a certain amount of the dry carrier material, with the formation of the lubricant carrier layer on the material arranged at least in regions within the container the pressure body surrounding the material can be set in motion in such a way that Uniform contact contacts over the surface of the material mechanically press, rub or press the dry carrier material between them onto the surface of the material.
- the rather small particles of the dry substance are firmly pressed into the existing material roughness.
- the device can have a screw, injector or dry dipping system; a preferred embodiment of the device according to the invention will be explained in more detail in the description of the figures.
- the invention makes the coating extremely simple and economical to carry out. It is only necessary to fill the dry carrier material for the pressure bodies in the container. In the following, it then only needs to be ensured that there is always a sufficient "reservoir", ie the dry carrier material only needs to be supplemented by the amount consumed. Disposal or basic emptying is advantageously completely eliminated.
- the pressure elements can advantageously also be formed by the dry carrier material itself, in that it consists of larger particles or parts in granule or pellet form.
- different shapes and / or sizes are preferably combined with one another in such a way that a coarse fraction and a fine fraction are formed, the coarse fraction acting as a pressure body and at the same time rubbing to form finer particles, which then mechanically separate from the larger particles on the material surface be pressed on.
- the fine fraction thus arises practically "by itself", so that essentially only the coarse fraction needs to be refilled.
- a device which is very similar to the coating device according to the invention is preferably provided, which has a container for holding a large number of loose, dimensionally stable grinding media which surround the material arranged at least in regions within the container and can be set in motion in such a way that they pass through the material - Evenly touching the surface mechanically remove the backing.
- the wire can be treated in a straight line in the pulling direction in a continuous process, so that there is no unforeseen or undefined elongation of the wire.

- FIG. 3 shows a longitudinal vertical section through the descaling device in the section plane III-III according to FIG. 2,
- FIG. 4 shows a plan view in the direction of arrow IV according to FIG. 1 of a “dry coating device” according to the invention
- FIG. 5 shows a longitudinal vertical section through the coating device in the section plane V-V according to FIGS. 4 and
- FIG. 6 shows a transverse vertical section through the descaling or coating device in the section plane VI-VI according to FIG. 3 or FIG. 5.
- a wire material 1 preformed by hot rolling is cold-formed in a continuous pass, the so-called drawing process, for which purpose it is at least one drawing station 2, but usually successively by several Pull stations one after the other, is pulled.
- Each drawing station 2 consists, in a manner known per se, of a drawing nozzle 4 (drawing die, in particular made of diamond or hard metal) and one of these upstream lubricant containers 6, in which there is a powdered solid lubricant based on metal soap, through which the wire material 1 is drawn. that lubricant particles adhere to the wire and are taken into the drawing nozzle 4 in the direction of arrow 7 and form a separating lubricating film there.
- a previous descaling (removal of a surface oxide layer) is provided, and on the other hand after the descaling in a coating device 10 according to the invention a lubricant carrier layer is provided on the surface of the wire material 1 forms, and according to the invention in a novel dry coating process, which will be discussed in more detail below.
- the descaling of the wire material 1 takes place in particular mechanically (dry descaling) and can be carried out by repeatedly bending the wire material 1 in a known bending descaling device 12 by deflecting the wire material 1 several times via deflection rollers or rollers 14.
- a novel “linear descaling device” 16 is provided according to the invention.
- This descaling device 16 will now be explained in more detail with reference to FIGS. 2, 3 and 6.
- she has a trough-like container 18 for receiving a large number of loose grinding bodies 20 (only shown in FIG. 3), which surround the material 1 arranged at least in some areas within the container 18 and can be set in motion in such a way that they are moved by Remove the scale layer mechanically from the material surface, even contact contacts (mechanical pressure, impact and / or friction).
- a conveyor screw 22 is preferably mounted within the container 18 so that it can be driven in rotation.
- This screw conveyor 22 consists of a worm shaft 24 and a web-like worm gear 26 that winds helically around the worm shaft 24.
- the worm gear 26 has a cylindrical lateral surface in the axial projection, and the bottom of the container 18 is accordingly concavely curved such that the worm gear 26 is slightly spaced from the container bottom over a circumferential gap.
- the worm shaft 24, which is in particular arranged approximately horizontally, has an axial machining channel 28 for the passage of the wire material 1.
- the worm shaft 24 is practically tubular.
- the screw shaft 24 has a radial passage opening 30, 32 for the grinding media 20, the screw conveyor 22 being driven in the direction of the arrow 34 depending on its screw thread direction in such a way that the grinding media 20 - see this 3 - be moved in a circuit, specifically outside the processing channel 28 and the worm shaft 24 in the container 18 in a direction opposite to the drawing direction (arrows 36) of the wire material 1 (arrow 38), then through the first Passage opening 30 inwards into the processing channel 28 into and there in the direction of drawing 36, where they are mainly carried along by the wire material 1 moving in this direction and during which remove the scale layer by constant contact and thereby form scale particles 40.
- the grinding bodies 20 together with the scale particles 40 then exit the machining channel 28 again via the second passage opening 32 of the worm shaft 24, in particular due to gravity, and into the region of the container 18 surrounding the screw conveyor 22.
- the grinding media 20 are then moved back in the direction of arrow 38, etc ..
- the container 18 in its lower region, ie in the region of its base, Sieböffnun ⁇ gene 42 such that the scale particles 40 fall due to gravity from the container 18 (see arrow 44 in Fig. 3), while the grinding media 20 are kept in circulation in the container 18.
- lugs 46 are expediently arranged in a distribution that is uniform over the length and the circumference of the machining channel 28.
- the lugs 46 are preferably arranged radially and can be formed by pins or rivets which are inserted into the wall of the hollow worm shaft 24 and fastened there.
- cross-sectional constrictions (not shown) distributed over its length can also be formed within the machining channel 28.
- Det be so as to generate a pressure on the wire material 1 via the grinding media 20.
- an axial wire inlet opening 48 leading into the container 18 and the processing channel 28 is provided on the one hand, and an axial wire outlet opening leading outwards from the processing channel 28 and the container 18 on the other hand 50, wherein the inlet opening 48 and the outlet opening 50 each have a preferably slightly larger diameter than the wire material 1 in order to enable a practically friction-free relative movement.
- a scraper for retaining the scale particles 40, that is to wipe 'or cleaning may be provided (not shown).
- the grinding media 20 to be used according to the invention are preferably at least approximately spherical and consist of a relatively hard, dimensionally stable material, in particular of ceramic material or of steel. Magnesium silicate or aluminum oxide is particularly suitable.
- the diameter of the grinding media 20 is preferably in the range from 3 mm to 25 mm.
- the dry coating device 10 according to the invention, which has already been briefly mentioned above, will now be explained in more detail.
- this device 10 corresponds principally and structurally largely to the descaling device 16 according to the invention, so that for more detailed information reference can be made to the above description in this regard, the same parts each having the same Reference numerals are provided. In the following, only specific differences will be discussed in more detail.
- the container 18 thus serves the coating device 10 to accommodate a large number of loose pressure bodies 52, which basically correspond to the grinding bodies 20 of the descaling device 12 and / or can be formed from larger particles (pellets) of a special dry carrier material 54.
- this special dry carrier material 54 is poured into the container 18 in powder and / or granule form — optionally in addition to the dimensionally stable pressure bodies 52.
- the pressure bodies 52 can be set in motion within the container 18 such that they mechanically apply the finer dry carrier material 54 contained between them as a lubricant carrier layer to the surface of the material 1 by means of uniform contact contacts across the material surface. This is practically a pressing, pressing, rolling or rubbing, whereby in any case the particles are pressed into the surface depressions of the material 1.
- the movement of the pressure bodies 52 is also brought about essentially by the screw conveyor 22.
- the wire inlet opening 48 here also preferably has a slightly larger diameter than the wire material 1, in order to ensure a smooth or low-friction movement .
- the outlet opening 50 is preferably adapted in its diameter to the wire material 1 and the desired layer thickness of the lubricant carrier layer in such a way that the desired layer thickness is achieved by stripping off a part of the - actually "thicker" formed within the processing channel 28 - Lubricant • carrier layer is set.
- the pressure elements 52 can correspond to the grinding elements 20 of the descaling device 16, and / or at least a partial amount of the pressure elements are formed by the then - granulate or "pellet" -shaped dry carrier material 54 itself.
- the container 18 of the coating device 10 is of course closed in its lower, tub-like area, ie has no screen openings or the like as the descaling device 16.
- a dry carrier material 54 is preferably used, which consists of a particular powdery and / or granular dry formulation which preferably contains fillers and a soap portion in certain proportions.
- the fillers primarily adhere to the material 1 and for this purpose preferably consist at least in part of metal oxides and / or metal salts.
- the soap portion consists in particular of a metal soap or of a mixture of several (for example two) metal soaps and provides a primer for a dry lubricant to be subsequently applied in the drawing station 2 by reacting the soap portions with one another.
- the dry formulation according to the invention preferably contains a relatively high filler content of in particular about 70 to 98% by weight and a relatively low soap content of in particular about 2 to 30% by weight.
- a soap-based dry lubricant with a very high soap content and a low filler content can then preferably be used. According to the invention, it is therefore a "shift" of the fillers causing the adhesion to the material into the dry carrier material according to the invention.
- the low percentage of soap in the dry carrier material only acts as a connection component to the solid lubricant. According to the invention, however, it can also be provided that the dry carrier material already has sufficient lubricating properties due to a higher percentage of soap, so that it may even be possible to dispense with a solid lubricant to be applied subsequently.
- Fillers about 38% by weight of titanium dioxide, about 38% by weight of lithium phosphate and about 15% by weight of magnesium oxide as well
- Soap content about 9% by weight zinc stearate.
- Potassium soaps have special advantages in that quick and easy cleaning of lubricants is required for the finished material.
- a water-soluble lubricant layer can advantageously be achieved with potassium soap components.
- a dry carrier material based on potassium soap shares has the following advantages over, for example, potassium and sodium soap shares:
- a dry carrier material with a potassium soap content is advantageously suitable for doing without a subsequent solid lubricant during the drawing process and nevertheless producing good lubricating properties, especially if the potassium soap content is above 70%.
- Materials which have been coated with potassium soap dry carrier material can advantageously also be processed very well in a subsequent wet shaping process or wet drawing process, without the need for a further lubricating component.
- the dry-coated material only needs to be exposed to water, which immediately results in a surface that can be deformed in terms of lubrication technology, namely by means of emulsion or dispersion, depending on the exact drying recipe.
- the following surprising advantage also arises that the adhesion properties of the deformed material or wire with other materials, such as rubber, are influenced very positively. This represents a major advantage for the tire industry, for example represents, where steel wires are connected with rubber (steel cord - tyrecord wire).
- Such formulations are used wherever the coating is highly insoluble, e.g. arrives for sealing the surface (so-called separating lubrication).
- a connection or reaction of the dry carrier with a solid lubricant or wet lubricant (also mineral oil) or water does not take place.
- the descaling device 16 is not limited to use in or before the coating method according to the invention, but can also be used independently of it, i.e. can also be used detached from a cold forming process for removing an oxide layer or the like surface layer - for example before a subsequent painting process or the like.
- the coating device 10 can in principle be used for any type of dry coating, ie not only for applying lubricants or lubricant carriers, but also, for example, for the formation of corrosion protection layers or similar coatings that are Leave to dry.
- a coating material in dry form is then filled into the pressure bodies and / or as pressure body in the container 18.
- the device 10 or 16 is thus generally said to be a "device for applying or removing a surface layer onto or from a material, in particular onto / from wire material in a continuous pass", which also can be used regardless of the specific application in cold forming processes.
- the invention is thus not limited to the specific embodiment and application example shown and described, but also includes all the embodiments, variants and applications having the same effect in the sense of the invention. Furthermore, the invention is in no way limited to the features contained in each of the independent claims, but can also be defined by any other combination of certain features of all the individual features disclosed in the application as a whole. This means that practically every single feature of each independent claim can be omitted or replaced by at least one single feature disclosed elsewhere in the application. In this respect, the claims have so far only been understood as a first attempt at formulating an invention.
