    The invention relates to a device for releasably holding a welding wire in a welding wire guide.
    In welding wires, which are unwound from a supply reel and usually conveyed by a Fihrungsschlauch, under certain operating conditions, the welding wire should be axially held against its guide, for example in the range of a hose coupling for connecting the guide hose or in the region of a burner, so that the burner side End of the welding wire relative to the burner can not shift axially.
    The invention is therefore based on the object to provide a comparatively simple device, by means of which a welding wire can be securely held within a welding wire guide against axial displacement, and to enable the welding wire automatically when releasing the welding wire lock.
    The invention achieves the stated object in that the welding wire guide (4) comprises a cage (5) for radially displaceable brake body (6), wherein the brake body (6) encloses a locking cone (7) and that of the two cooperating, on the one hand by the Welding wire guide (4) and on the other hand by the locking cone (7) formed functional elements one in a holder (3) against displacement and the other against the shift-resistant Funktionsele-element against a spring force are axially displaceable.
    By providing two mutually axially displaceable functional elements, one of which forms a welding wire guide with a cage for radially displaceable brake body and the other a locking cone for these brake body, advantageous conditions for a secure locking of the welding wire within the welding wire guide are ensured because with the relative Move the locking cone with respect to the locking wire passing through the locking wire guide the brake bodies are pressed radially over the locking cone to the welding wire and this almost 25/09/2012 14:19

    Rrhwpiftrirahtfiihn neffirrert μμγΗβπ Irann never 7 ») The han hbp tion and the locking cone effective spring force can be used depending on the application to ensure the free welding wire or the welding wire lock. The spring force is adjusted accordingly by the choice of the spring and adapted accordingly to the diameter of the welding wire.
    If the welding wire lock used in conjunction with a hose coupling for connecting a guide tube for the welding wire, so simple design conditions arise when the holder for the two functional elements forms one of two nested coupling parts of a hose coupling, the other coupling part an actuating stop for the axially displaceably mounted , Having acted upon by a spring in the locking direction functional element. Due to the effective locking in the spring spring when locking the coupling of the welding wire is locked on the acting on the brake body locking cone within the welding wire guide.
    When coupling the two coupling parts are inserted into each other, wherein the loaded by the spring in the locking function element abuts an actuating stop of the opposite coupling part and is retained by this against further entrainment, so that when passing through the further coupling path, the axially displaceable functional element against the force of the spring the functional element mounted displaceably in the holder is displaced and therefore the brake bodies are released from the locking cone. With the complete coupling of the two coupling parts of the hose coupling thus given in the open clutch welding wire lock is automatically released.
    Although it is not important for the function of the welding wire lock whether the welding wire guide is mounted so as to be axially displaceable relative to the locking cone or the locking cone in relation to the welding wire guide, P.005 / 015 25/09/2012 14:19 Nr .: R050 3/14 25th SEP. 2012 14:21 +43 7242 241 5638 NR. 825 p. 6
    ben particularly favorable construction conditions, when the holder forms a plug-in projection of the coupling part, and when on the extension of the plug-extending, non-sliding welding wire guide the locking cone is guided displaceably. In this case, there is no relative movement between the welding wire guide and the welding wire during both locking and unlocking. For the displaceably mounted on the welding wire guide locking cone results in an advantageous travel, because yes the welding wire guide extends the plug neck of the coupling part, which also brings advantageous design conditions for the retention stop of the male connector female coupling part, which in the coupled state, the welding wire lock with the spring enclosing protective. For the application of the welding wire barrier in the region of a burner, the holder can aulweisen a cylinder for a drive-connected with the displaceably mounted functional element, loaded with the spring force piston, which is acted upon by a pressure medium against the spring force. Depending on the direction of action of the spring force is blocked or released by the pressure medium of the piston, the welding wire within the welding wire guide. In general, it is in this context advantageous if the axially displaceable mounted in the holder welding wire guide has the acted upon in the unlocking sense with the spring force piston and when the holder forms the locking cone. The spring force provides in this case for unlocking the wire lock, which is only turned on when the piston is acted upon by a pressure medium accordingly.
    In general, it is therefore advantageous that the welding wire can be fixed in its position during service measures, parts replacement or the like, but also for so-called teach operations. The fixation is independent of the wire feed motor or the wire feed motor detects the fixation and stops during the fixation, the promotion of the welding wire. Thus, the wire feed motor, which is often far away and arranged in other rooms, does not have to be manually switched off and on again. 25/09/2012 14:19 No .: R050 4/14 P. 006/015 25.

    In the drawing, the subject invention is shown, for example. Show it
    Fig. 1 shows an inventive device for releasably holding a
    Welding wire on the example of a hose coupling with separate coupling parts in a simplified longitudinal section,
    2 the hose coupling according to FIG. 1 in the coupled state, FIG.
    Fig. 3 shows an inventive device in conjunction with a welding torch, not shown in a simplified longitudinal section in the unlocked position and
    Fig. 4 shows the device of FIG. 3 in the locked position.
    1 and 2, a hose coupling with two plug-in coupling parts 1,2 is provided, of which the one coupling part 2 has a plug neck of the coupling part 2 forming holder 3 for a sleeve-shaped welding wire guide 4, in the region of the plug extension end region Cage 5 for radially adjustable, spherical brake body 6 forms. On this non-displaceably connected to the holder 3 welding wire guide 4, a locking cone 7 is mounted axially displaceable, which cooperates with its contact surfaces with the brake bodies 6 and is acted upon by means of a spring 8 in Verriege-lungssinn, on the one hand to the holder 3 and on the other hand Verriegefungskonus 7 is supported. The spring action of the locking cone 7 thus causes, as shown in FIG. 1, a radial pressing of the spherical brake body 6 to the welding wire 9 extending through the welding wire guide 4. For example, three brake bodies 0 are each staggered by 120e. Accordingly, therefore, the locking cone 7 encloses the brake body 6. Thus, a corresponding weld wire lock is effected, as shown in FIG. 1 can be removed. The position of the axially conveyed welding wire 9 is therefore fixed by the brake body 6 when the coupling parts 1, 2 are opened or not coupled. Thus, the welding wire 9 is a resistance for a wire feed motor, so that it automatically stops the promotion. Such a wire feed motor and its arrangement in a Drahtvorschubge- appliance, a welding torch or the like are sufficient from the date of 25/09/2012 14:20

    Technique known, so this is not shown and will not be discussed in detail.
    2, the welding wire guide 4 engages with the locking cone 7 in the insertion opening 10 of the Kuppiungsteils 1 until the locking cone 7 abuts a retention stop 11 of the coupling part 1 and against further penetration into the insertion opening 10 is prevented. This means that the locking cone 7 is moved against the force of the spring 8 in Entriegelungssinn on the welding wire guide 4 until the secured by locking balls 12 of the coupling part 1 coupling position is reached, in which the spherical brake body 6 are completely released by the locking cone 7 so that the welding wire 9 can be conveyed through the welding wire guide 4 unhindered by the wire lock formed by the brake bodies 6.
    To release the hose coupling, first the locking balls 12 of the coupling part 1 are to be released via a securing sleeve 13 that can be displaced axially against spring force, before the two coupling parts 1 and 2 can be moved apart. In this case, the locking cone 7 is pressed by the spring 8 back into the locking position of FIG. 1, whereby the welding wire 9 is clamped in the welding wire guide 4 via the brake body 6.
    In the embodiment according to Figures 3 and 4, the device for releasably adhering the welding wire 9 is shown in conjunction with a welding torch, not shown, since this is well known in the prior art. The displaceably guided in a holder 3 welding wire guide 4 forms a piston 14 of a resulting in the holder 3 cylinder 15. This piston 14 is loaded on one side by a spring 8 and can via a pressure medium connection 16 on the opposite side against the spring force with a Pressure medium to be acted upon. The spherical brake bodies 6 are held in a cage 5 on the side of the welding wire guide 4 which is chamfered on the spring 8 and cooperate with a locking cone 7 formed by the holder 3. The locking cone 7 encloses the 25/09/2012 14:20 Nr .: R050 6/14 P. 008/015 25. SEP. 2012 14:22 +43 7242 241 5638 NR. 825 p. 9

    Brake body 6, which are arranged according to the number offset by the respective degrees. So with three Bremskörpem 6 offset by 120®.
    If the pressure medium connection 16 without supply, the spring 8 comes into action, which acts on the welding wire guide 4 via the piston 14 in Entriegelungssinn, so that the brake body 6 are released by the locking cone 7 and the welding wire 9 can be promoted unhindered by the welding wire guide 4, as this is shown in FIG. 3.
    If the piston 14 is acted on via the pressure medium connection 16 with a pressure medium, so supplied for example with compressed air, the welding wire guide 4 is displaced against the force of the spring 8 in the locking direction, wherein the spherical brake body 6 are pressed radially over the locking cone 7 to the welding wire 9 and clamp it against axial displacement as shown in FIG. 4 as long as the pressurization pressure of the piston 14 is maintained by the pressure means. 25/09/2012 14:20
