Definitions

  • the invention relates to a device for cleaning a gas nozzle of a welding torch with a rotating tool which can be inserted into an intermediate space formed between a contact nozzle (current nozzle) of the welding torch and the gas nozzle.
  • welding spatter occurs, which preferentially settles on the gas nozzle and must be removed from time to time.
  • cleaning stations are already known, such as from DE 33 32 678 C2, DE 34 21 885 C2 or WO 96/23619. Milling cutters are usually used as cleaning tools. However, in the case of a conically shaped gas nozzle with a corresponding design of the contact tip, the use of cutters is no longer possible, since practically only the tip of the gas nozzle can be cleaned from welding spatter.
  • the object of the invention is to provide a device for cleaning a gas nozzle of a welding torch of the type mentioned at the outset which enables effective cleaning even in the case of conically shaped gas nozzles with, if appropriate, the configuration of the contact tip.
  • this object is essentially achieved in the cleaning device of the type mentioned in the introduction in that the rotating tool has at least one, preferably a plurality of bristles.
  • the rotary movement of the bristles according to the invention enables effective cleaning even with conically shaped gas nozzles with a suitable configuration of the contact tip, since the welding spatter adhering to the walls is completely removed by brushing. This gentle way of cleaning
  • CONFIRMATION COPY also ensures that there is no or no significant wear of the gas nozzle and contact tip.
  • the bristles are arranged on a circumference and are designed to be resilient. This facilitates the insertion of the bristles into the space formed by the gas nozzle and the current nozzle and enables particularly good cleaning. Furthermore, the elasticity of the bristles ensures that no stress, such as scoring, occurs on the surfaces of the gas and current nozzle to be cleaned after the welding spatter has been removed.
  • the bristles are held in pairs in the tool body to form U-shaped bristle elements.
  • Two bristles each form a U-shaped bristle element.
  • the fixation can take place, for example, in that corresponding bores are provided in the tool body, through which the bristles are pushed until the connecting web between the two bristles rests on the back of the tool body between the two bores. Then all that is required is a suitable anchoring of the bristle elements. Additionally or alternatively, it is also conceivable that the bristles or bristle elements are cast in the tool body.
  • the bristles have an outward bias. This achieves a further improvement in cleaning, as a result of which, in particular, residues of the brushed-off welding spatter are removed cleanly.
  • the bristles preferably have spherical thickenings preferably in the area of their free ends. This will make the The effectiveness of cleaning is increased, since the spherical thickening can also be used to remove particularly resistant weld spatters.
  • the bristles consist of elastic plastic, in particular polymer plastic, or metal. These materials ensure both the required dimensional stability and the elasticity of the bristles.
  • the bristles are advantageously arranged within a centering sleeve or insertion sleeve and are pushed into the space between the gas nozzle and the current nozzle for cleaning beyond the sleeve. This facilitates the insertion of the bristles into the space between the gas nozzle and the contact tip. Furthermore, the effectiveness of the cleaning process is increased again, since the cleaning can already start when the bristles are inserted into the gas nozzle.
  • a receptacle for inserting and centering the gas nozzle in a coaxial alignment with the axis of rotation of the bristles is arranged, preferably molded, on the axial end of the centering bushing or the insertion sleeve opposite the bristles. This enables simple insertion of the bristles into the gas nozzle.
  • the centering bush or the insertion sleeve and the receptacle are held on a, preferably rotationally secured holder, the gas nozzle being displaceable in the axial direction together with the holder.
  • the brush can be placed on an output shaft of a drive by means of a thread. This enables time-saving replacement of the used bristles.
  • a cutting disk for cutting off a wire electrode of a welding torch is arranged on the output shaft of the drive. This enables the wire electrode to be shortened, so that welding balls which preferentially settle at the tip of the wire electrode when the welding process is ended can also be removed quickly.
  • the cutting disc is accommodated in a cover which, for the insertion of the wire electrode, has an opening aligned axially to the axis of rotation of the drive on the circumference of the cutting disc. This enables the welding electrode to be cut off at a defined distance from the gas nozzle or current nozzle.
  • the cleaning device has a spray unit for spraying the cleaned gas nozzle with release agent. This creates a compact cleaning station with an integrated injection unit.

  • a tool 3 which in the exemplary embodiment selected here has a plurality of bristles 5 arranged on a circular circumference and is set in rotation by means of a drive 14.
  • the bristles 5 engage in an intermediate space 10 formed between a contact nozzle or a current nozzle 4 of the welding torch 1 and the gas nozzle 2 and cause the welding spatter to be completely removed by brushing.
  • the bristles 5 are designed to be resilient and consist of spring steel in the exemplary embodiment selected here. Of course, it is also possible to manufacture the bristles 5 from polymer plastic or other materials. This elasticity of the bristles 5 ensures the required dimensional stability and facilitates their introduction into the intermediate space 10 formed by the gas nozzle 2 and the current nozzle 4. The resilient design of the bristles 5 also brings about a gentle cleaning, since there is no wear in after the welding spatter has been removed Form of, for example, grooves on the surfaces of the gas nozzle 2 and the current nozzle 4 to be cleaned.
  • a non-rotatable holder 12 Arranged between the welding torch 1 and the bristles 5 is a non-rotatable holder 12 which has a receptacle 11 for inserting and fixing the gas nozzle 2. This ensures that reaction forces caused by the rotary movement of the bristles 5 cannot be transmitted either to the gas nozzle 2 or to the mechanics of the feed device for axially displacing the burner during the cleaning process.
  • a centering bushing or insertion sleeve 9 for inserting and centering the bristles 5 is formed at the axial end of the receptacle 11 opposite the gas nozzle 2, the axis of rotation of the bristles 5 being aligned coaxially with the gas nozzle 2.
  • the diameter of the centering bushing 9 is adapted to the opening diameter of the gas nozzle 2.
  • the bristles 5 are received within the centering bushing 9.
  • the bristles 5 have an outward bias so that they adapt to the inner wall of the gas nozzle 2 during subsequent cleaning.
  • the welding torch 1 is moved, for example by means of a robot arm, in the direction of the arrow according to FIGS. 1 and 2 to the rotating brush 3, so that the bristles 5 extend beyond the insertion sleeve 9 into the space 10 between the gas nozzle 2 and the contact tip 4 intervene and remove welding spatter from the gas nozzle.
  • the bristles 5 can have spherical thickenings in the region of their free ends, as a result of which particularly resistant welding spatter can also be removed.
  • the pretensioning of the bristles 5 ensures that they rest on the inner surfaces of the gas nozzles 2 even with conically shaped gas nozzles 2, with a corresponding design of the current nozzle 4, so that any remaining welding spatter on the walls is complete be removed. Overall, this results in a particularly effective cleaning, since the rotating bristles 5 come into effect during the entire process of the entry and exit movement.
  • the machining tool 3 has an internal thread on its shaft for coupling to a drive shaft 15 of the drive 14. This ensures a time-saving replacement of a used bristle tool 3.
  • FIG. 4 shows the possibility of integrating the cleaning device into a cleaning station 21.
  • This cleaning station 21 also has a spray unit 20 which is used to spray the cleaned gas nozzle 2 with a separating agent.
  • the release agent is supplied and the release agent is sprayed by means of a pump 27.
  • the spray unit 20 or an injector is fastened in the cleaning station 21 by means of a holder 25 and has an opening 26 in the housing for receiving the gas nozzle 2.
  • the cleaning station 21 is provided with a separating unit 16 for cutting off a wire electrode 17 of the welding torch 1 with a separating unit 16, which is arranged projecting beyond the lateral edge of the housing of the cleaning station 21. This makes it possible to shorten the wire electrode 17 and thus to remove welding balls, which are preferably deposited on the tip of the wire electrode 17 when the welding process is ended.
