    The invention relates to a plug-in part for detachably connecting a liquid-cooled welding torch with a bushing part arranged on a hose package, having an end face, a cylindrical tubular element, at least two axially extending welding wire channels, at least two cooling channels, each with an orifice, and at least two welding power lines, each having a contact region.
    Furthermore, the invention relates to a socket part for releasably connecting a hose assembly with a liquid-cooled welding torch, with a cylindrical end piece, with at least two axially extending welding wire channels, at least two cooling channels, each with an orifice, and at least two welding power lines, each having a contact region.
    Finally, the invention relates to a connecting device for releasably connecting a liquid-cooled welding torch with a hose package and an adapter element for detachable connection of a liquid-cooled single-wire welding torch with a hose package of a multiwire welding torch.
    US 6,683,279 Bl shows a double-wire welding torch which is detachably mounted on a hose assembly. The assembly of a connector part connected to the welding torch is carried out directly or via a connecting body to a socket part, which is connected to the hose package. From the plug part protrude two welding power lines, which protrude into corresponding openings on the socket part. The welding power lines simultaneously serve as welding wire channels. On the plug part cooling channels are arranged with check valves. Such connecting devices for double-wire welding torches can be used only conditionally for high currents, which may exceed 2 × 300 A, and welding or burn-off of the contact surfaces on the plug part and / or socket part can occur.
    The object of the present invention is to provide a plug part, socket part, a connection device and an adapter element of the specified type, by which a releasable connection of a welding torch can be provided with a hose package, which is also suitable for high welding currents and use in hollow shaft robots. Disadvantages of the prior art should be avoided or at least reduced.
    The object is achieved by an abovementioned plug part, in which each welding current line is arranged around a cooling channel at least in the area of the end face, and the contact area of each welding current line is arranged axially offset from the mouths of the cooling channels. By arranging the welding current line around the cooling channel at least in the region of the end face of the plug part, a particularly reliable cooling of the welding current line and the contact region can be achieved. Since the contact area is one of the limiting elements for the transmission of high welding currents, the better and more uniform cooling also enables the transmission of higher current densities. Inadmissibly high heating of the contact areas and associated damage due to burning or fusion can be reliably avoided with this cooling of the welding power lines and their contact areas. Due to the axially staggered arrangement of the contact areas and mouths of the cooling channels also a particularly compact design and thus a small outer diameter of the tubular element of the plug part can be achieved. Accordingly, the plug part is also suitable for use in welding torches with hollow shaft robot.
    The compact space-saving design can be improved if the mouths of the cooling channels are arranged projecting from the end face and the contact areas of each welding power line between the end face and mouth of the cooling channels are arranged. In addition, this arrangement can contribute to the formation of a cylindrical contact surface of the contact region, which favors a uniformly distributed power transmission to the socket part.
    Preferably, the contact areas of the welding power lines are silvered, whereby the contact resistance can be reduced and thus the power transmission can be improved.
    If a pin-shaped element, which may possibly be resiliently mounted, is provided on the end face of the plug part for receiving in a corresponding receiving opening of the socket part, the correct angular position of the plug part can be determined for the socket part, thus preventing incorrect mating.
    If the welding current lines are formed by a tube of conductive material at least in the region of the contact regions, the contact region of the welding current line can be formed by the lateral surface of the tube, which allows relatively large contact surfaces.
    If each welding power line concentrically surrounds at least one cooling channel in the region of the contact region, the contact area of each welding current line can be uniformly cooled by the enclosed cooling channel. This promotes the transmission of high welding currents or only allows the transmission of high welding currents, for example of 2 x 600 A and more in a confined space.
    The structure of the plug part can be simplified structurally if each welding power line forms a cooling channel at least in the region of the contact region. In addition, such a structure causes the direct contact of the cooling liquid with the welding power line, whereby the cooling of the contact area is supported.
    A favorable spatial arrangement of the cooling channel, welding power line and welding wire lines while maintaining the necessary isolation distances can be achieved, that in the region of the end face the welding power lines with the cooling channels and the welding wire channels are arranged diametrically to each other and preferably at equal angular intervals. In the case of a two-wire welding torch so the welding power lines are arranged at 90 ° to the welding wire channels angularly offset.
    If interchangeable valves are preferably arranged in the cooling channels in the region of the orifices, it is possible to prevent leakage of the cooling liquid when the connection between the plug part and the socket part is disengaged.
    If the valves are arranged in current thorns, which form current spikes the contact areas of the welding power lines, maintenance can be facilitated and downtime or maintenance intervals of the welding torch can be reduced. So wear parts, such as current arbors and valves and seals can be changed in one step, whereby the maintenance can be reduced.
    Due to the construction of the plug part according to the invention, an outer diameter of the cylindrical tubular element of less than 80 mm, in particular between 50 mm and 65 mm, can be achieved. Such dimensions of the plug part are characterized for use in hollow shaft robots.
    If the cylindrical tubular element in the region of the end face with insulating material, in particular epoxy, shed, the lines and channels can be fixed in position and it can be maintained the necessary insulation resistance. This can further improve a compact space-saving design of the plug part.
    The object is also achieved by a bushing part mentioned above in which each welding current line is arranged around a cooling channel at least in the region of the end piece, and the contact region of each welding current line is arranged axially offset from the mouths of the cooling channels. If ever a cooling channel surrounded by a welding power line at least in the region of the end of the socket part, a particularly reliable cooling of the welding power line and in particular their contact areas can be achieved in the socket part, as by this arrangement, the welding current line and thus the contact area directly or indirectly over the mantle Cooling channel is cooled. As a result, the transmission of high welding currents, for example in the range of 2 × 600 A and more, is made possible without undue heating of the contact areas and associated damage due to burn-off or merging. Characterized in that contact regions of the welding power lines are arranged axially offset from the mouths of the cooling channels, an unobstructed flow of the cooling liquid and thus improved cooling in the region of the contact areas is achieved. Furthermore, a particularly compact design can be achieved by the axially staggered arrangement of contact areas and openings, which also allows use in hollow shaft robots.
    The current transmission between socket part and plug part can be further improved if the contact region of each welding current line has at least one contact element, in particular a contact spring or contact strip. This contact element can increase the contact pressure on the contact region of the plug part, whereby the contact resistance in the current path of the connection socket part to plug part can be kept small. In addition, for example, a contact spring or contact blades cause a large amount of contact points both to the contact region of the plug part and the socket part. The current can therefore be divided into many different paths, whereby the current load of the individual contact points - even at high welding currents - can remain within the permissible range. In conjunction with the cooling, welding currents of more than 2 x 600A can be transmitted.
    Preferably, at least the contact regions of the welding current lines are also silvered in the socket part, whereby the contact resistance can be reduced and the current transmission can be improved.
    If a receiving opening for receiving a corresponding pin-shaped element of the plug part is provided on the cylindrical end piece of the socket part, the desired angular position of the socket part can be set to the plug part.
    If the welding current lines are formed by a tube of conductive material at least in the region of the contact regions, the contact region can be formed by the lateral surface of the tube, which allows relatively large contact surfaces. As a result, an improved distribution of the current flow with a lower contact resistance can be achieved.
    If interchangeable valves are preferably arranged in the cooling channels in the region of the orifices, it is possible to prevent the coolant from escaping when the connection of the plug part is disconnected from the socket part. If the valves and any seals are made replaceable, downtime of the welding torch can be reduced.
    Advantageously, the outer diameter of the cylindrical end piece of the socket part is less than 80 mm, in particular between 50 mm and 65 mm. Such small dimensions also sign out the female connector for use with hollow shaft robots.
    If the cylindrical end piece is encapsulated with insulation material, in particular epoxy resin, both the position of the lines and channels can be fixed and the necessary insulation resistance can be maintained. This can improve a compact, space-saving design of the socket part.
    The object of the invention is also achieved by a connecting device for releasably connecting a liquid-cooled welding torch with a hose package, wherein the welding torch has a connector part mentioned above and the hose package has a female part described above.
    Finally, the object is also achieved by an adapter element mentioned above for the detachable connection of a liquid-cooled single-wire welding torch with a hose package of a multiwire welding torch, wherein the adapter element for the single-wire welding torch has a connector part described above. As a result, a simple change between single and multi-wire welding torch can be realized on one and the same hose package.
    The subject invention will be explained in more detail below with reference to the accompanying figures which show by way of example, schematically and not by way of limitation advantageous embodiments of the invention. Show

    Fig. 1 shows a connecting device 1 for releasably connecting a liquid-cooled multi-wire welding torch 2 with a hose package 3. The connecting device 1 includes a plug part 4 on the multiwire welding torch 2, and a matching or corresponding female part 4, which is attached to the hose package 3 , The multiwire welding torch further includes a burner body 15 and a gas nozzle 16. In this embodiment, a shutdown box 6 and a robot flange 7 are additionally shown, through which substantially the hose package 3 is guided and which are arranged on the last robot axis (as shown) when used with a robot. In the cylindrical tubular element 8 extend two axial Schweißdrahtkanäle 10, two cooling channels 11, two welding power lines 12, a protective gas line 13 and a Ausblasluftleitung 14, as will be explained in more detail below with reference to Figures 2 to 5. About a union nut 65, the plug part 4 can be screwed and secured with the socket part 5. In general, it is stated that the proposed allocation plug part 4 to multi-wire welding torch 2 and socket part 5 to 3 hose package is not mandatory. It is equally conceivable that the female part 5 on the multiwire welding torch 2 and the male part 4 on the hose package 3 are arranged to produce a detachable connection between the welding torch 2 and the hose package 3.
    As can be seen from the view according to FIG. 2, the outer jacket of the plug part 4 is formed from a cylindrical tubular element 8. In the cylindrical tubular element 8 extend two axial Schweißdrahtkanäle 10, two cooling channels 11, two Schweißstromleitungen 12, a protective gas line 13 and a Ausblasluftleitung 14 from the end face 9 on to the burner body 15 and through this to the gas nozzle 16. In the welding wire channels 10 are welding wires (not shown) promoted to contact tubes in the gas nozzle 16. The current for generating the arc, in particular work arc, between the electrode or the welding wire not shown in detail and formed from one or more parts workpiece is via the welding power lines 12 and their contact areas 17 via the welding power lines 20 and their contact areas 18 of the female part 5 (see Fig. 3) supplied. The cooling of the multi-wire welding torch 2 via a cooling liquid, which is conveyed via corresponding cooling channels 11. The cooling channels 11 of the plug part 4 open into corresponding openings 19. In the cooling channels 11 valves 27 may be arranged to prevent leakage of the cooling liquid in the dissolved connection of the plug part 4 from the socket part 5.
    Depending on a welding current line 12 surrounds at least in the region of the end face 9 of the plug part 4, a cooling channel 11 and is preferably arranged concentrically around this. Thus, a particularly reliable cooling of the welding current line 12 and in particular of the contact region 17 of the welding current line 12 is achieved. In particular, the contact region 17 is one of the limiting elements for the transmission of large currents from the female part 5 to the plug part 4. The cooling of the welding power line 12 and the contact region 17 according to the invention enables the transmission of higher welding currents. Inadmissible heating of the contact areas 17 and associated damage due to burning or merging are reliably avoided.
    In addition, the contact areas 17 of the welding power lines 12 are arranged axially offset from the openings 19 of the cooling channels 11. Accordingly, the transitions of the cooling liquid and the welding current are arranged directly one after the other, which, when the plug part 4 and the socket part 5 are connected, allows unhindered coolant flow and thus reliable cooling in the area of the contact areas 17. Likewise, a mechanical stabilization of the contact region 17 is achieved by the orifices 19, so that a uniform power transmission is ensured.
    The staggered arrangement of contact areas 17 and openings 19 also allows a particularly compact design, which allows a small outer diameter of the cylindrical tube member 8. This allows the use of the connecting device 1 for hollow shaft robot.
    In the plug part 4, a possibly resiliently mounted pin-shaped element 29 can be arranged on the end face 9, which fits into a corresponding receiving opening 30 of the socket part 5 (see FIG. 3). As a result, a certain angular position of the plug part 4 is predetermined to the socket part 5. In addition, a device for electronic identification 31 of the welding torch can be provided on the plug part 4. This electronic identification 31 makes it possible to verify the connection between the socket part 5 and the plug part 4 or between the associated hose package 3 and multiwire welding torch 2, which prevents the use of incompatible combinations. In addition, any data of the multi-wire welding torch 2 can be transmitted to the hose package 3. In order to achieve a compact arrangement, protective gas line 13, pin-shaped element 29, blow-out line 14 and electronic identifier 31 are arranged essentially on a circle 32 on the plug-in side 9. On an axis 33 between electronic identifier 31 and pin-shaped element 29, the welding wire channels 10 are arranged substantially diametrically to each other center near. Along an axis 34 which extends between the welding wire channels 10 and through the center 35, welding power lines 12 and the cooling channels 11 enclosed or formed by the welding current line 12 are arranged diametrically opposite one another. The axis 33 and the axis 34 are arranged substantially 90 ° to each other. This allows, despite a compact, space-saving design to comply with the necessary distances for isolation.
    In the area of the contact areas 17, the Schweißstromleitun conditions 12 may be formed of a conductive tube 36, which tube 36 each preferably a cooling channel 11 concentrically surrounds. Since the cooling channel 11 does not have a separate jacket in this region, a cooling channel 11 is formed by the inner circumferential surface of the welding current lines 12. Thus, the compact design is achieved at the same time optimal cooling and also allows use with smaller hollow shaft robots.
    The welding power lines 12 of the plug part 4 can be designed as exchangeable current mandrels 37, which comprises the mouth 19 and the contact area 17. The valves 27 of the cooling channels 11 are preferably interchangeable together with any seals 38 with the current thorns 37 in one step. For this purpose, the current mandrels 37 are attached via a thread 67 to an associated Stromdornaufnahme 68. In the current mandrel 37, the cooling channel 11 preferably has two different diameters, the diameter being greater in the region of the valve 27. Necessary maintenance of both the current thorns 37 and the valves 27 can be carried out quickly, which significantly reduces downtime.
    The above-mentioned structural measures allow a compact design of the detachable connection between the plug part 4 and socket part 5, the outer diameter smaller than 80mm, in particular between 50mm and 65mm, allow. As a result, use is possible even with a hollow shaft robot.
    The arrangement of the welding wire channels 10, welding power lines 12 and cooling channels 11 can be fixed by casting the tubular element 8 with insulating material 39. A suitable insulation material 39 is, for example, epoxy resin. In addition, the casting of the tubular element 8 also serves for the insulation of the individual welding wire channels 10 and welding wire leads 12. In this case, the tubular element 8 can be cast completely or else only in the area of the end face 9.
    The socket part 4 corresponding to the female part 5 is shown in Fig. 3 in more detail. The female part 5 can be connected directly, but also via a shut-off box 6, a robot flange 7 or also via other connecting elements with the hose package 3. The socket part 5 has a cylindrical end piece 21 with two axially extending welding wire channels 41 for, two welding power lines 20 each having a contact region 18. The welding power lines 20 are sheathed in the region of the contact region 18 with an insulating sleeve 40 in order to be able to comply with the necessary insulating distances and safety measures. Furthermore, a protective gas line 43 and a blow-out air line 44 and two cooling channels 22 for the forward and return of the cooling liquid are arranged. For connection of the cooling channels 22 with the corresponding cooling channels 11 in the plug part 4 are at the end piece 21 of the female part 5 corresponding mouths 45 of the cooling channels 22, which coincide with the mouths 19 of the cooling channels 11 in the plug part 4, so that the cooling liquid unhindered to the end of the multi-wire Welding torch 2 can flow. In the socket part 5, a receiving opening 30 for receiving the pin-shaped element 29 of the plug part 4 and contacts 46 for receiving the electronic identifier 31 of the plug part 4 may be arranged.
    Also in the socket part 5 are in the region of the end piece 21 each have a welding current 20 each arranged around a cooling channel 22, preferably concentric with each other. Thus, a particularly reliable cooling of the welding current line 20 and in particular their contact areas 18 is achieved in the socket part 5, since the welding current line 20 and thus the contact area 18 comes into direct contact or indirectly via the jacket of the cooling channel 22 with the cooling liquid. The contact areas 18 of the welding power lines 20 are arranged axially offset from the openings 45 of the cooling channels 22, which allows an unimpeded flow of the cooling liquid and thus reliable cooling in the area of the contact areas 18 and also a particularly compact design.
    The preferably silvered contact areas 17 of the welding current lines 12 of the plug part 4 or contact areas 18 of the welding current lines 20 of the socket part 5 are particularly suitable for the transmission of high welding currents, as this further reduces the contact resistances.
    The welding power lines 20 can also be formed in the contact region 18 from a conductive tube 47, which encloses the cooling channel 22 concentrically. The mouths 45 of the cooling channels 22 may also contain valves 23 to prevent leakage of the cooling liquid when the connection device 1 is disconnected. The valves 23 and any wearing parts, such as seals 48, which must be changed regularly, are preferably carried out interchangeable in one step. Overall, the above-mentioned structural measures allow a compact design.
    Also on the socket part 5, the welding wire channels 41, welding power lines 20, cooling channels 22, etc. by casting the cylindrical end piece 21 with insulating material 49, such as epoxy resin, fixed and isolated from each other.
    If the plug part 4 is connected to the socket part 5 (see FIG. 4), the contact regions 17 of the welding current leads 12 of the plug part 4 abut against the contact regions 18 of the welding current leads 20 of the socket part 5. During the connection of the male part 4 with the female part 5, the valves 27 of the cooling channels 11 protruding from the welding current lines 12 of the male part 4 are in engagement with the corresponding valves 23 of the cooling channels 22 of the female part 5, whereby the valves 27 and 23 are opened. The cooling fluid flows unhindered through the interior of the welding power lines 12 and 20 and cools them accordingly. Thus, the welding power lines 12 and 20 are in direct contact with the cooling liquid, whereby the contact areas 17, 18 are cooled indirectly via the welding power lines 12 and 20.
    The detachable connection of a liquid-cooled multiwire welding torch 2 with a hose package 3 via the described plug part 4 and socket part 5 can be done with a union nut 65 with an internal thread 64 which engages in an external thread 63 arranged on the end piece 21 of the socket part 5. The union nut 65 is arranged on the plug part 3 via a clamping ring 66. In addition to this connection variant, other possibilities of connection, such as an exchange coupling for an automated burner replacement are conceivable.
    As can be seen from the detail view in FIG. 5, the contact areas 18 of the welding current lines 20 of the socket part 5 can have grooves 24 for receiving a contact element 25, such as a contact spring 26. This contact spring 26 increases the contact pressure on the contact region 17 of the welding current line 12 of the plug part 4, whereby the contact resistance is kept low. In addition, the contact spring 26 causes an increase in the number of contact points 28 both to the contact portion 17 of the male part 4 and the contact portion 18 of the female part 5. The current is therefore divided into many different paths, whereby the current load of the individual contact points 28 can be kept low , In conjunction with cooling via the cooling channels 11, 22, welding currents of more than 2 × 600 A can be transmitted. Instead of a contact spring 26 and a plurality of contact springs 26 or contact blades (not shown) can be used to improve the contact.
    A different application example of the plug part 4 for a liquid-cooled welding torch is shown with reference to FIGS. 6 to 9. In this case, the plug part 4 is not part of a liquid-cooled multi-channel welding torch 2, but part of an adapter element 50 between the female part 5 of a hose package 3 for a liquid-cooled multiwire welding torch 2 and a liquid-cooled single-wire welding torch 2 '. For this purpose, the adapter element 50 is equipped with a plug part 4 (essentially according to FIG. 2) in order to allow a detachable connection with the socket part 5 according to FIG. 3 of the hose package 3. For connection to the single-wire welding torch 2 ', the adapter element 50 on the opposite side of the plug 4 a socket part 5', which is compatible with a plug part 4 'of the single-wire welding torch 2' is executed. The socket part 5 'has on its end face 51 a central welding wire channel 53, two cooling channels 54, the mouths 55 are equipped with valves 56, a common shielding gas Ausblasluftkanal 57, contacts 58 for the electronic identification of the single-wire welding torch 2' and a welding power line 59th In the cylindrical tube element 8 of the plug part 4 of the adapter element 50, the current-carrying, cylindrical body 60 is arranged to conduct the welding current and to receive the current mandrels 37. In the cylindrical body 60 of the adapter element 50, the two welding wire channels 10 are brought together on a welding wire channel 53, which allows a mutual welding with one of the two welding wires, not shown. In addition, in the adapter element 50, the welding power lines 12, protective gas channel 13, blow-out air channel 14, cooling channels 11 and electronic identifier 31 for connection to the corresponding channels 54, 57 and lines 58, 59 on the female part 52 reoriented. This is at least partially apparent from FIG. 9. On the socket side, only one welding current line 59 in the form of the current-carrying, cylindrical tube element 60 is present, wherein the current transmission to the single-wire welding torch 2 'is tubular in the edge region of the socket part 52. The end face 61 of this welding current line 59 forms the contact region 62 for the single-wire welding torch 2 '. This adapter element 50 thus allows easy to handle change between single and multi-wire welding torch.
