    The invention relates to a method for cleaning linearly extended objects, wherein a substantially annular nozzle carrier is moved in the longitudinal direction relative to the object, wherein a cleaning medium is blown onto the object via nozzles attached to the nozzle carrier to remove oil or other foreign matter adhering to the object ,
    In the production of high-quality technical components, it is usually necessary to carry out cleaning steps in order to remove any residues of exciting processing, such as chips, oil or grinding emulsions. This is done in many cases by blowing off with a cleaning medium such as compressed air.
    It is known to move an annular nozzle carrier relative to the object for cleaning elongate components, such as axles, camshafts, spindles or screws, thereby directing the cleaning medium from nozzles attached to the nozzle body to the object. Typically, the object is clamped with a horizontal axis and the nozzle body is moved along the axis.
    In this context, however, the above definition also includes situations in which the axis of the object is perpendicular or the object is moved relative to the nozzle body. It is essential that the nozzle body has an extension in the longitudinal direction, which is significantly lower than that of the object and therefore the cleaning process proceeds progressively along the longitudinal axis.
    It is known to carry out such a cleaning in such a way that in the nozzle body a plurality of nozzles are arranged in the circumferential direction next to one another, which are directed approximately or exactly on the longitudinal axis of the object to be cleaned. At the same time, the nozzles are generally arranged obliquely with respect to the longitudinal axis, so that the nozzle axes, for example, span a cone with the vertex on the longitudinal axis of the object. The cleaning takes place in such a way that the cleaning medium occurring on the object - typically compressed air - is removed from the object and transported away in the longitudinal direction. Of course, the direction of movement of the nozzle carrier corresponds to the direction in which the nozzles are inclined so that the foreign bodies are blown away towards the not yet cleaned side of the object. 2 * * · · · * ·· ···· · ♦ * * * * · * * *
    This known device is successful, for example, fn cfer: * ·· ·· · «· * * # ·
    Automotive, since it is possible in this way to clean camshafts, screws or the like efficiently. However, a disadvantage is the relatively high air consumption, which requires a corresponding energy consumption, and the fact that a plurality of nozzles must be provided to securely detect each point of the workpiece.
    Object of the present invention is to avoid these disadvantages and to provide a solution in which the air consumption can be reduced and the technical structure can be simplified.
    According to the invention, at least part of the nozzles is directed into an annular gap between the object and the nozzle carrier tangentially to the object. This means that these nozzles, which are referred to as swirl nozzles in the sequence, perform a completely different effect than the nozzles in the method and the device according to the prior art. Namely, these nozzles do not produce an air jet directed perpendicularly or at an angle to the workpiece to directly remove foreign matter, but serve primarily to create a swirling flow in the annular gap between the object and the nozzle carrier. Therefore, such nozzles for better distinction here called swirl nozzles. The axes of these swirl nozzles are not directed to the object itself, but are tangent to the object or pass it.
    Thus, what is essential is the above-described swirl flow or swirl flow, which makes it possible to achieve at least the same cleaning effect with an overall significantly lower air quantity as in the case of processes according to the prior art. It is also different from the prior art that it is not necessary to tilt the nozzles longitudinally to blow away the foreign matter. By the swirl flow or vortex flow, a centrifugal force is generated, which removes the foreign body radially outward. Another aspect of the invention is that now with a substantially small number of nozzles Auslangen can be found, since the flow also transports foreign matter from locations that are not directly detected by the jet. Thus, it is particularly possible to provide nozzles in the circumferential direction only at one or two locations, so to find in extreme cases with a single swirl nozzle Auslangen. 3
    The method of the present invention is suitable not only for cylindrical objects, but also for elongated objects of more complex shapes, such as camshafts. In this case, it is of course necessary to allow the movements in the longitudinal direction at all, that the lumen of the nozzle carrier is greater than the envelope of all cross-sections of the camshaft. In this case, the swirl nozzles are, for example, directed tangentially to this envelope, in order to produce a swirl flow, which ensures safe removal of the foreign bodies also around the cams. On the other hand, it can be observed inadequate cleaning of the areas of smaller diameter between the cam. In such a case, a part of the cleaning medium is preferably directed more strongly to the longitudinal axis via separate nozzles, that is, at least in the region of the cams, the cleaning medium is directed directly onto the object. In the sections between the cams in turn there is then tangential flow.
    Furthermore, the present invention relates to a device for cleaning linearly extended objects, having a substantially annular nozzle carrier, which is movable in the longitudinal direction relative to the object, wherein the nozzle carrier at least one nozzle is formed to blow a cleaning medium to the object to oil or remove any foreign objects adhering to the object.
    According to the invention, it is provided that the at least one nozzle as a swirl nozzle is directed tangentially to the object in an annular gap between the object and the nozzle carrier. Such a device allows an improved utilization of the given amount of air and therefore an improved cleaning effect with respect to the amount of air used or generally to the amount of the cleaning medium.
    An extension of the residence time of the cleaning medium in the annular gap can be achieved, in particular, by virtue of the fact that the at least one swirl nozzle has an axis which lies in a plane which is substantially perpendicular to the axis of the object. This allows a further increase in efficiency.
    If several swirl nozzles are provided, it is particularly advantageous that they are aligned in the same direction of rotation, d. H. When viewed in the longitudinal direction, they all blow either clockwise or counterclockwise. The several 4 a · · ft * ··· ** ·· ···· ··· * ·
    In this case, swirl nozzles can be arranged offset in the axial direction next to one another pdpr ip UrpfgngsrjchSupg ····· ··· ·· · m.
    In the case of complicatedly formed contours of the object, it may be necessary to provide at least one blowing nozzle, which is directed directly onto the object, in addition to the at least one swirl nozzle. In this way it is possible to locally modify the mainly effective swirl flow to also effectively clean concave areas or undercuts. It is particularly advantageous if the bias nozzle has an axis which is more inclined in the radial direction and more in the axial direction than the axis of the at least one swirl nozzle.
    A particularly favorable embodiment of the device according to the invention is given when the annular gap has a thickness of between 5% and 20% and preferably of the inner diameter of the nozzle carrier. Moreover, it is favorable if the nozzle carrier has an axial extent which is at least 80%, preferably at least 120%, of the inner diameter of the nozzle carrier. In this way, a high degree of efficiency can be ensured with the least possible effort.
    In the following, the present invention will be explained in more detail with reference to the embodiments illustrated in FIGS. 1 shows schematically a device according to the invention; 2 shows a first embodiment of a nozzle carrier in a view in the axial direction. Fig. 3 shows a second embodiment of a nozzle carrier in a view in the axial direction with an object to be cleaned.
    Fig. 1 shows schematically a device according to the invention, comprising a housing 1, which has at its end faces receptacles 2, 3 for an object to be cleaned, which in the present case is a camshaft 4. A nozzle carrier 5 can longitudinally not shown on guides, not shown. along the double arrow 6 relative to the camshaft 4 are moved back and forth. The nozzle carrier 5 has a plurality of nozzles 7, via which a cleaning medium, for example compressed air, can be blown into an annular gap 8 between the camshaft 4 and the nozzle carrier 5. The longitudinal axis of the camshaft 4 is denoted by 4a. 5 ················································ «
    In Fig. 2, the nozzle carrier 5 of Fig. 2 is made up of two-jawed tubes, and has a lumen 18 of circular cross-section, can be moved through an object, not shown here. A nozzle 7 is aligned as a swirl nozzle with an axis 7 a so that the distance d from the longitudinal axis 4 a is about 90% of the radius r of the lumen 18.
    FIG. 3 shows an alternative embodiment variant in a corresponding illustration corresponding to FIG. 2. The object to be cleaned is a camshaft 4 with a longitudinal axis 4a. The camshaft 4 consists of a cylindrical body 5, on which three cams 10a, 10b and 10c are formed, which are offset at equal angular intervals of 120 ° to each other, as is typically the case with V6 engines. 2 arranged on the outer periphery so that the blown cleaning medium, represented by the arrow 11, is guided circularly along the annular gap 8, which is not occupied by the camshaft lumen 18 of Camshaft 4 represents. In addition to the swirl nozzles 7, a blowing nozzle 10 is provided, whose axis 10a is parallel to the axis 7a of the blowing nozzle 7, but which is arranged further inside. This means that the tuyere 7 is directed directly to the camshaft 4 in the region of the cams 10a, 10b and 10c, but is likewise arranged tangentially in the region of the shaft section 9, as can be seen from the further arrow 12 for the tuyere 10.
    The annular gap 8 has a comparatively small thickness, which is for example 10% of the inner diameter r of the nozzle carrier 5 and preferably between 5% and 20% and the inner diameter D = 2. r. The width of the nozzle carrier 5, i. its axial extent should be at least 80%, preferably at least 120% of the inside diameter 2. r of the nozzle carrier 5 amount.
    Both the swirl nozzles 7a and the blowing nozzle 10 are in the embodiment of Fig. 3 with their axes 7a and 10a in the plane of representation or parallel to it. However, one or more of these nozzles may also be slightly inclined to the plane of the illustration, if required. that the jet from this nozzle or from these nozzles has a slight component in the axial direction.
