The invention relates to a flexible pipe bend for a welding torch, wherein at one end a nozzle for receiving a contact tube and a gas nozzle and at the other opposite end a central terminal for fixing the pipe bend is arranged on a burner holder, wherein the two ends via a flexible connecting element with each other are formed, which for the stable positioning of the arc components, in particular a welding wire or an electrode, and for receiving a wire guide core and / or the welding wire or the electrode is formed, and which is prepared for guiding a protective gas in its interior. The connecting element comprises a flexible actuating arm and a power cable ge, as described in the preamble of claim 1.
From the Austrian application A2009 / 01245 a flexible pipe bend for a welding torch is already known, in which at one end a nozzle for receiving a contact tube and a gas nozzle and at the other end opposite a central terminal for fixing the pipe bend is arranged on a burner holder, wherein the both ends are connected to each other via a flexible connecting element. The connecting element is designed such that a mechanical separation for the stability and the current transmission is provided by a Steliarm for stable positioning of the arc components, in particular a welding wire or an electrode, is provided. To the Steliarm a highly flexible power cable is laid, and the Steliarm is designed to receive a wire guide core and / or the welding wire or an electrode. Within the actuator arm, a protective gas is guided. The power cable is formed of a mesh of high-strength and flexible individual strands, which preferably consist of the material copper. The actuating arm is formed from a well-known from the prior art corrugated hose, in particular a so-called gooseneck.
The disadvantage here is that with such a structure for the bending properties and positional positioning of the manually bent pipe bend is only provided as a gooseneck actuator arm is provided. Thus, all opposing forces act on this, so that over a longer period of time, the position is no longer held by the actuating arm and thus the contact nozzle or the welding wire is changed in its spatial position. In the case of automated applications, this has a very negative effect on the welding process, since the weld bead is no longer formed at the desired position.
Furthermore, solutions with copper spring wires or steel springs and copper wires are known, which, however, do not have sufficient service life. Normal Cu wires are used, but they do not have good bending properties and thus break. In such embodiments, the mechanical forces act directly on the Cu wires, so that they are deformed and thus break faster, since they can deform during the bending process.
The object of the invention is to provide a flexible pipe bend and a welding torch in which the aforementioned disadvantages of the inaccurate position holder are remedied or at least improved by the actuating arm.
This problem is solved for a flexible pipe bend in that the power cable is designed for guiding, shaping and stabilizing by a plurality of defined wound copper wires or copper pipes, and that the actuating arm at both ends in fixed connection with the copper wires or copper pipes, the continuous and alternating are connected on a plane wrapped around the actuator arm.
The advantage here is that a defined bending radius is set by the use of a Steliarmes in the form of a gooseneck, which is designed such that a promotion of the welding wire through the gooseneck tube is possible without problems. Another advantage is that it is now ensured by fixing the wires or tubes on the actuating arm that no change in length of the pipe bend during bending, as was the case in the prior art, since the highly flexible Stromka-bel not connected to the actuator arm was and thus can expand in a bending process, whereby the attached nozzle and / or central terminal was slightly shifted in length. Thus, with the new design, the accuracy is significantly increased because the TCP (Tool Center Point) does not change due to the bends. Another advantage is the use of multiple wires or tubes, resulting in the total cross-section of the sum of the individual cross-sections, so that the flexibility is possible and the power transmission for higher performance N201D / 27500 06/10 2010 MT .15: 49 [SE / RM NR 5845] @ 006 2S 15:51:06 06-10-2010 7/28 -3-is. Another significant advantage is that the supporting function of the actuating arm for the windings of the wires or pipes they are no longer deformed during bending and thus the life and the bending number are significantly increased.
Another significant advantage is that due to the arrangement of the wound copper wires or copper pipes even a large bending angle of the Verbindungsseie-mentes causes no or minimal deformation of the wires or pipes.
Furthermore, it is advantageous that a longitudinal expansion and rotation of the connecting element is prevented by the mutual stabilization of the defined wound electrically conductive copper wires or copper tubes. By using the actuating arm, a defined minimum radius is created during bending, which can not be undershot, thus ensuring unimpeded conveyance of the welding wire.
Due to the configuration that the copper wires or copper pipes are fixedly connected to the ends of the actuating arm, is achieved in an advantageous manner that thereby a security against rotation is created, since the individual spirals or wound wires stabilize each other and prevent rotation. This also ensures that an exact length stability is achieved, since the wires or tubes can not move in a bending operation relative to the steep arm in their length, so that the components attached thereto are also fixedly defined.
It is also an embodiment of advantage in which the copper wires or the copper pipes each have a diameter between 3 and 5mm, preferably 4mm, as this also the wires are formed for receiving the bending forces and thus the actuating arm is supported in the position stabilization.
But it is also advantageous if the number of copper wires or copper tubes is adapted to a required total cross section between 30mm2 and 50mma depending on the required burner performance, as this is the formability and stability regardless of the Brennerieistung.
It is also advantageous if the copper wires or copper tubes are arranged at an angle between 65 ° and 75 ° to the longitudinal axis of the actuating arm or the welding torch, so that the deformability and stability is specified or defined.

A further advantageous embodiment is achieved in that the actuating arm of a flexible, but semi-rigid arm of coiled metal hose, in particular of a gooseneck tube is formed, as a high stability for the wound copper wires or copper tubes is achieved, since this serves as a support body , In addition, it is also achieved that the use of a gooseneck tube, a defined minimum radius is given, and thus the copper wires or copper pipes are not overstressed, so that the number of possible bending cycles for such a copper wire or such a copper tube is substantially increased,
Bel an embodiment of the invention, in which the beginning and the end of the copper wires aufgeteiit evenly connected to a diameter of a transition piece and are connected to this, is achieved in an advantageous manner that so that attachment of the other components is easier possible.
Finally, an embodiment is advantageous in which the copper wires or copper tubes are insulated from each other. This is achieved in an advantageous manner that no arcing between the turns in a bending process can occur.
Further advantageous embodiments are described in the description of the figures. The resulting benefits may also be taken from this description.
The present invention will be explained in more detail with reference to the accompanying schematic drawings.

In Fig. 1, a welding apparatus 1 or a welding system for a variety of processes or processes, such. MIG / MAG welding or TIG / TIG welding or electrode welding, double wire / tandem welding, plasma or soldering, etc. are shown.
The welder 1 comprises a power source 2 with a power arranged therein
The control device 4 is connected, for example, to a control valve which is located in a supply line for a gas 5, in particular an inert gas , such as C02, helium or argon and the like., Between a gas storage and a welding torch 7 and a burner is arranged.
In addition, a wire feeder 8, which is customary for MIG / MAG welding, can be actuated via the control device 4, wherein a filler material or a welding wire 9 from a supply drum 10 or a wire reel into the area of the welding torch 7 via a supply line is supplied. Of course, it is possible that the wire feeder 8, as is known from the prior art, in the welder 1, in particular in the housing 11 of the power source 2 is integrated and not, as shown in Fig. 1, as an additional device on a carriage 12th is positioned. Here is spoken by a so-called "compact welding machine" 1. It is also possible that the wire feeder 8 can be placed directly on the welding device 2, that is, that the housing 11 of the power source 2 is formed on the top for receiving the wire feeder 8, so that the carriage 12 can be omitted.
It is also possible for the wire feeder 8 to supply the welding wire 9 or the additional material outside the welding torch 7 to the process elements, for which purpose a non-consumable electrode is preferably arranged in the welding torch 7, as is customary, for example, in TIG / TIG welding.
The current for building up an arc 13, in particular an arc of work between the electrode or the welding wire 9 and a workpiece 14 preferably formed from one or more parts, is not shown to the welding torch 7, in particular the electrode or the welding wire 9, via a welding line (not shown) ) supplied from the power part 3 of the power source 2. The workpiece 14 to be welded is connected via a further welding line for a further potential, in particular via a ground cable, to the current source 2 (not shown). In this way, a circuit is closed via the arc 13 or the plasma jet formed for a welding process. When using a torch with internal arc 13, the two welding lines (not shown) are guided to the burner, so that in the burner, a corresponding circuit can be constructed, as in plasma N2010 / 27500 06/10 2010 MI 15:49 [SE / EM NR 58451 ®010 15:52:08 06-10-2010 11/28 25 15:52:08 06-10-2010 11/28 25

Brenner can be the case.
For cooling the welding torch 7, the welding torch 7 can be connected via a cooling device 15 with the interposition of other components, such as a flow monitor, with a Fiüssigkeitsbehälter, in particular a water tank 16 with a level indicator 17, whereby the cooling device 15, in particular one for the in the water tank 16 arranged liquid used liquid pump is started at the start of the welding torch 7, whereby a cooling of the welding torch 7 can be effected. As shown in the illustrated embodiment, the cooling device 15 is positioned on the carriage 12, on which then the power source 2 is set. The individual components of the welding installation, that is to say the current source 2, the wire feeder 8 and the cooling unit 15, can be designed in such a way that they have corresponding projections or recesses, so that they can be safely stacked on top of each other.
The welding device 1, in particular the current source 2, further has an input and / or output device 18, via which the most varied welding parameters, operating modes or welding programs of the welding device 1 can be set or called up and displayed. In this case, the welding parameters, operating modes or welding programs set via the input and / or output device 18 are forwarded to the control device 4, from which subsequently the individual components of the welding system or the welding device 1 are actuated or corresponding setpoint values for regulation or control are specified. Here, it is also possible that when using a corresponding welding torch 7 and adjusting operations on the welding torch 7 can be made, the welding torch 7 is equipped with a welding torch input and / or Ausgabevorrichiung 19. Preferably, the welding torch 7 is connected via a data bus, in particular a serial data bus, to the welding device 1, in particular the current source 2 or the wire feed device 8.
To start the welding process, the welding torch 7 usually has a starting switch (not shown) so that the arc 13 can be ignited by actuating the start switch. In order to be protected against the high heat radiation from the arc 13, it is possible that the welding torch 7 is equipped with a heat shield 20.

Furthermore, the welding torch 7 is connected in the illustrated embodiment via a hose package 21 to the welding device 1 or the welding system, the hose package 21 is attached via a bend protection 22 on the welding torch 7. In the hose package 21 are individual lines between the welding device 1 and the welding torch 7, such as the supply line or lines for the welding wire 9, for the gas 5, for the cooling circuit, for the data transmission, etc. in contrast, the ground cable is preferably connected to the extra power source 2. The hose package 21 is connected via a coupling device (not shown) to the power source 2 or the wire feeder 8, whereas the individual lines are secured in the hose assembly 21 with a kink protection on or in the welding torch 7. So that a corresponding strain relief of the hose assembly 21 is ensured, the hose package 21 can be connected via a strain relief device (not shown) with the housing 11 of the power source 2 or the wire feeder Θ.
In principle, it should be mentioned that not all of the previously named components must be used or used for the different welding methods or welding apparatuses 1, such as, for example, TIG devices or MIG / MAG devices or plasma devices. In contrast, it is possible, for example, that the welding torch 7 can be designed as an air-cooled welding torch 7, so that, for example, the cooling device 15 can be dispensed with. It can therefore be said that the welding device 1 can also be formed merely by the current source 2, the wire feed device 8 and the cooling device 15, wherein these components can also be arranged in a common housing 11. Furthermore, it is possible that even more parts or components can be arranged or used, such as a grinding guard 23 on the wire feeder 8 or an option carrier 24 on a holding device 25 for the gas storage 6, etc.
FIGS. 2 to 11 show a flexible pipe bend 29 for a welding torch 7. Flexible pipe bends are known per se. For example, a flexible pipe bend in the Austrian application A 2009/01245 is included. The basic structure of such a flexible pipe bend is therefore not described here in detail, but it will only reference to the significant differences according to the invention between the pipe bend 29 according to the invention and known in the art pipe bends reference. N2010 / 27500 06/10 20.10 WED 15:49 [SE / KM NR 5845] @ | 012 25 15.52: 42 06-10-2010 13/28 -9-
As already known, the pipe bend 29 is formed such that at one end a nozzle 30 for receiving a contact tube 31 and at the other opposite end a central terminal 32 for fixing the pipe bend 29 to a burner holder (not shown) are arranged, wherein the two ends are connected to each other via a flexible connecting element 33. It is also possible that other components, such as a gas nozzle 34, a union nut 35 or the like, are fixed or arranged on the nozzle 30 or the central terminal 32.
In the illustrated pipe bend 29 of the nozzle 30 and the central terminal 32 are thus connected via the flexible connecting element 33, ie, that the curvature of the pipe bend 29 can be adjusted arbitrarily via the connecting element 33, so that an optimal adaptation of the nozzle 30, in particular from the Contact tube 31 exiting welding wire 9, can be made to a welding task. Thus, even hard to reach places can be welded in the usual welding position, since the user can easily bend the pipe bend 29, as shown for example in Figs. 7 to 11. Here it can be seen that the pipe bend 29 can be deformed / bent in a variety of ways and with different radii. It can be seen that the maximum bending radii are designed such that a perfect promotion of the welding wire 9 is ensured by the connecting element 33.
The connecting element 33 is designed in such a way that there is a mechanical separation for stability and current transmission, by providing an actuating arm 38 for stably positioning the arc components, in particular the welding wire 9 or an electrode (not shown). Preferably, the actuator arm 36 is also designed to receive a wire guide core and / or the welding wire 9 or for receiving a non-consumable electrode for a TIG / TIG burner, preferably further required for a welding process elements, such as the inert gas, within the actuator arm 38 are guided.
As Stellarm 38 is (as well as in the Austrian application A 2009/01245) a so-called gooseneck, as it is known from the prior art, used so that is dispensed with a detailed description of the structure. For example, such actuating arms 38 are sold by Boa AG of Rothenburg or Flex-perte www.flexperte.de under "Biegbare Arme" type: BA 151L11. This stellar
N2010 / 2750E 06/10 2010 MI 15:49 [SE / EM NF 5845] ®013 25 15:53:00 06-10-2010 14/28 I · · «t ··· * * ·» * Μ • · are flexible and rigid at the same time and consist of a combination of inner round wire with one from the outside indented triangular coil,
According to the prior art, now a highly flexible cable is laid around the control arm 38, which receives no mechanical forces to stabilize the position and thus is designed only for the power supply. In this design, the cable consists of sheer fine strands, so that this cable can easily bend, but does not dwell in this bent position without tools, but moves back into the straight starting position,
According to the invention, it is now provided that the power cable 39 is designed to conduct electricity and likewise to stabilize and position and shape the arc components, ie the nozzle assembly, by forming the power cable 3Θ from a plurality of defined copper wires or copper tubes 40, wherein the individual copper wires or Copper tubes 40 are continuously and alternately wound on a plane around the steep arm 38, that is, now that the actuator arm 38 and the power cable 39 independently of each other for receiving the mechanical forces, in particular the bending forces, restoring forces, etc "are formed, so a much better Form stability of the burner / pipe bend 29 is achieved because now two components for absorbing the forces are available. It can therefore be said that several copper wires or copper tubes 40 form the power cable 39. However, it is also conceivable that the power cable 39, i. the wires or tubes 40 provided for its construction can not consist of copper but also of other electrically conductive materials, such as, for example, silver or silver alloys.
In order to achieve a good length stability when bending, the copper wires or copper tubes 40 of the power cable 39 are fixedly connected to the ends of the actuator arm 38, thereby preventing them from being displaced beyond the actuator arm 38 during bending or from shortening. The stretching and shrinking processes that occur during bending are compensated by the individual windings, ensuring that the pipe bend length always remains the same. The attachment of the copper wires or copper tubes 40 on the stiffening arm 38 can be done for example via a ferrule and / or by soldering, but also any other suitable type of fastening, such as, terminals, rivets, welding, gluing, etc. can be used. At the same time, the other components, in particular the nozzle 30, the Zentraianschluss 32, also attached to the ends, ie, that N2010 / 27500 06/10 2010 Ml 15:49 [SE / EM NR 5845] @ 014 25 15:53:19 06-10-2010 15/28 * · · · · «· · 4 I * · # · * ····« · · «« < • · * * · «« Φ * * * I «| 4 * · I I · -11 - the gooseneck tube with the ends of the copper wires and / or the copper tubes 40 and the other components, in particular the central terminal 32 and the nozzle 30 are connected. Thus, this fixed connection prevents longitudinal expansion of the copper wires and / or copper tubes 40 and their rotation when bending the flexible pipe bend 29, since the actuating arm 38 serves as a support body. Likewise, this fixed connection of both components provides a minimum radius, so that a bending of the pipe bend 29 is prevented over a non-permitted radius. This radius is mainly defined by the construction of the gooseneck tube, that is to say that by using different swan neck tubes different burners with different bending radii can be made.
In order to allow a long life and a high number of bending operations for the pipe bend 29, it is necessary that the copper wires or copper pipes 40 are formed and wound up accordingly. The copper wires or copper tubes 40 each have a diameter between 3 and 5mm, preferably 4mm.
Depending on the required burner output, the individual copper wires or copper tubes 40 thereby form a total cross section between 30 mm 2 and 50 mm *, ie, the required cross section for a corresponding current conduction is divided among a plurality of copper wires or copper tubes 40, whereby the thickness of the tube bend 29, ie the outside diameter of the connecting element 33 can be reduced while improving the bending properties and the positional stability. So that a simple bending of the pipe bend 29 is possible, the orientation of the individual windings of the copper wires or copper pipes 40 to the longitudinal axis 41 of the pipe bend 29 is observed. Namely, if the winding is formed too flat, the bending properties are good in the horizontal direction, but very bad in the vertical direction and vice versa. In order to ensure good bending properties both in the vertical and in the horizontal direction, the copper wires or copper tubes 40 are preferably arranged at an angle 43 between 60 ° and 75 ° to the longitudinal axis 41 of the actuating arm 38 and the welding torch 7.
It should be noted in the design of the pipe bend 29 but also that the arrangement of several copper wires or copper pipes 40 rach possible in a plane. In this case, the beginning and the end of the copper wires or copper tubes 40 are evenly divided by a diameter of the actuator arm 38, in particular the gooseneck tube, and connected to these, as best seen in Fig. 3 in the region of the central terminal 32.

In the winding of the copper wires or the copper tubes 40 is alternately wound along the actuator arm 38, that is, for example, six copper wires or copper tubes 40 first all six in the first winding are arranged consecutively, and only then the second winding of the individual copper wires or copper tubes 40 and the other windings are formed. Thus, the wires always alternate. Preferably, the pipe bend 29 is wound with only one layer, wherein the wires preferably without gaps line up. The individual windings are also formed against each other insulating. Furthermore, it is achieved by the use of an actuating arm 38, that the winding shape of the copper wire or copper tube 40 is supported by the actuating arm 38 during bending, so that the copper wire or copper tube 40 can not buckle. Thus, the life and the bending number is significantly increased.
If the pipe bend 29 is used for a water-cooled welding torch 7, then it is recommended that individual copper pipes 40 are used, through which the cooling medium is guided. Here, it is possible that, for example, three of six copper tubes 40 are used as supply lines and the other three copper tubes 40 are used as return lines, wherein the corresponding connections of the ends of the copper tubes 40 is integrated in the nozzle or is produced by additional lines. But it is also possible that all copper tubes 40 are ausgebiidet as supply lines and the return line within the actuator arm 38 extends or all lines are arranged for cooling within the actuating arm 38, but advantageously a gooseneck tube is used with a larger diameter. Preferably, copper tubes 40 are used therein. For the dimensioning of such a pipe bend 29 or welding torch, for example, in a water-cooled burner, a diameter of copper pipes 40 of 3 to 4mm 4 to 7 copper tubes 40 are used, so that a total cross section between 25 and 35mm2 results and thus a power transmission to 520A possible is. A typical dimensioning for an air-cooled burner, for example, be such that a 3 to 4mm thick copper wire 40 is used, are arranged by the four to seven individual copper wires 40 on the circumference, so that a total cross section of 40 to 50mm2 is achieved, and thus a power transmission up to 320A is possible. Both welding torches 7 or elbows 29 have the same outer diameter of the connecting element 33. Of course, it is also possible to produce more powerful or weaker pipe bends by appropriate dimensioning.

It is also possible that instead of round copper wires or copper tubes 40 other shapes, such as triangular wire helixes are used, which in turn should be sized for the corresponding power range.
In order to protect the user from electric shock, the current-carrying parts, in particular the actuator arm 3B, with the power cable 39 wound thereon are covered with a protective hose 49, in particular a rubber hose, as can be seen in FIGS.
Of course, it is possible that the previously described pipe bend 29 is also used in a welding torch 7, that is, that the flexible pipe bend 29 Fix or plug is attached to the burner handle, so that the user can bend the pipe bend 29 before or during the welding process.
