Definitions

  • This invention relates to a burner for electric are metal coating of the type having a system for guiding the wire electrodes, for stabilizing the position of both fusible arc electrodes wires and for enabling a correct guiding of wires, even when the electrodes have irregularities.
  • the burner for metal coating by means of an electric arc comprises a burner body with a guiding insert with guiding grooves for both are electrodes.
  • a pair of first spring loaded chucks urges the electrodes against the guiding insert, and a pair of second spring loaded chucks close to the fusing ends of the electrodes secures the correct position of the fusing ends of both electrodes.
  • Stop means determines the initial position of the pair of second Chucks.
  • a supporting piece 7 for the. arc electrodes 8 and 9 is inserted into the end of burner body 6.
  • the end of the body 6 is provided with external threads and the internal surface of body 6 widen towards its end.
  • a guiding insert 1 is fixed in the central part of the supporting piece 7, said guiding insert 1 having guiding grooves for both are electrodes 8 and 9.
  • the supporting piece 7 is secured in the burner body 6 by a covering nut 4 threaded on the external thread of the burner body 6.
  • the electrodes may be driven by conventional means 20, 21, as shown by the arrows, for example as shown in US. Pat No. 3,141,616, and are connected to suitable terminals 22, 23.
  • a pair of supporting bolts 10 are provided in the supporting piece 7, supporting pivotably a pair of first chucks 2 and another pair of supporting bolts 11 are provided supporting pivotably a pair of second chucks 3.
  • Each chuck 2 and 3 has a recess 12 and 13, respectively, opposite to each other.
  • the supporting bolts l0 and 11 are mutually offset and a common spring 5 extending between the recesses 12 and 13 generates a pressure urging the chucks 2, 3 against the electrodes 8, 9 leaning against the guiding insert 1.
  • the pair of chucks 2 and 3 and the guiding insert 1 are at least partially made of some electrically insulating and abrasion resistant material as, for instance, of fused corundum, so that both are electrodes 8 and 9 are mutually electrically insulated.
  • the guiding insert 1 is stable and determines by its guiding grooves the position of the are for I straight arc electrodes 8, 9.
  • the are electrodes 8, 9 rest against the guiding insert 1 along two of their generating lines of their surface.
  • the springs 5 enable the first chucks 2 and subsequently also the second chucks to recede so that the irregular part of the arc electrode can pass without difficulty.
  • a common spring 5 is shown in the drawing acting simultaneously to both chucks 2 and 3. It is understood that alternatively each chuck 2 or 3 can be urged against the arc electrodes 8, 9 by its own spring. A still better stability of the arc can be achieved, if the chucks 2 and 3 are also provided with guiding grooves for the arc electrodes 8, 9.
  • the second chucks 3 rest in their initial position with their rear part against the internal surface of the covering nut 4, which simultaneously secures the supporting piece 7 in the burner body 6. If arc electrodes 8, 9 of different cross sections have to be used, special stop means must be provided for adjustment of the correct initial position of the second chucks 3.
  • the improved stability of the ends of the fusible arc electrodes ensures a quietbuming of the arc and a uniform fusion of the metal, which is particularly of importance for mechanized metal coating, where the individual coating tracks join one another to form a continuous coating.
  • the uniformity of thickness of the deposited layer on each place is directly proportional to the uniformity of fusion of the metal of the arc electrodes.
  • a pair of second spring loaded insulated chucks close to the fusing ends of the wire electrodes, securing the correct position of the fusing ends of the electrodes, and stop means positioned to determine the initial position of said second chucks.
  • An arrangement for guiding a pair of wire electrodes connected to driving means and electric terminals of a burner for metal coating by means of an electric arc comprising in combination:
  • an insulating guide insert mounted in said burner body and having guiding grooves for guiding said wire electrodes at an angle to each other
  • said chucks being positioned with each group of one first and one second chuck engageable with a separate electrode and the second chucks being closer to the fusing ends of said electrodes than said first chucks;
  • stop means positioned to limit the displacement of said second chucks toward said electrodes.
