Definitions

  • the invention includes an elongated tubular member having a spray 266/6 %2l1:18/l1/2g I nozzle at one end which is axially movable with Fieid 148 149 spect to a stationary housing.
  • the housing includes T "IL;"I6"i f /Z R means for supplying the medium to be sprayed to the S 148/1216 tubular member and thus the spray nozzle for any i axial position of the tubular member.
  • heat treatment is accomplished by exposing the body to be treated to the spray medium issuing from a plurality of nozzles. Because the bodies to be treated are often multicontoured bodies, it is important, for a high-quality job of heat treating, that the various nozzles be adjustable so that the distance of the nozzles from the work piece may be varied. In the past, the adjustment of the position of the nozzles with respect to the work piece was accomplished by securing the-spray nozzle with their tubes in a holder such that the various nozzles and tubes could be interchanged. Because of the exchangeability of the various tubes, a longer or a shorter tube could be used, depending upon the diameter of the axially symmetrical metal body to be' treated.
  • the spray-heat treatment apparatus permits the continuousradial adjustment of the spray nozzles'with respect'to the body to be treated without keeping nozzles with various tube length-in stock, which have to be exchanged. Since the housing for the tube of each nozzle is fixed, without-impairing the radial adjustability of the spray nozzles. This is of advantage as far as the construction and sealing is concerned.
  • the tube carrying the spray nozzle is guided at the points at which it extends from the housing by stuffing boxes.
  • This guidance results, on the one hand, in a tight seal, and on the other-hand, it permits the selective displacement of the tubes in the housing-
  • the stuffing boxes can be braced axially again at the tube by axially acting bracing means.
  • the spray the holder in one or several rows staggered angularly around the metal body.
  • the holder is designed as a supporting arm and can be swung out of its operating position above the metal body.
  • FIG. 4 is a plan view partially in section of the con- I necting means between the spray tube and housing.
  • FIG. 5 is a cross sectional view of the central part of the spray tube and housing.
  • the spray-heat treatment apparatus of the present invention includes a support stand having two end blocks 1 and 2 which engage a multi-contoured axially symmetrical metal body 5 which is to be heat treated.
  • the metal body 5 is contacted at its end faces by the tips 3 and'4.
  • the tips 3 and 4 are adjustable'in an axial direction to secure the body 5 to be treated in the proper axial position and to prevent axial displacement of the body 5.
  • Between the end blocks 1 and 2 are two roller blocks 6 and 7 which are adapted to support the body SQMounted on each of the roller blocks 6 and 7 are a pair'of movable carriages23 and 24 which rotatably support the rollers 8,
  • roller 10 which are in turn adapted to carry and support the metal body
  • a second roller 10 corresponding to the illustrated roller'10 6 or 7 is coupled or associated with a driving motor to permit the metal body '5 to be set in rotation.
  • the support stand further includes means for supporting a plurality of spraying assemblies in a spraying position.
  • This means includes a supporting arm 11 ex-.
  • the supportin'garm 11 is secured by two substantially U-shaped arms mounted in :the part 12 to permit the support means to be pivoted out of its operating position and nozzles with their tubes and housing can be secured in includes three support brackets 26 which are axially parallel to the main axis A.
  • the supportbrackets 26 of the supporting arm 11 carry three straight rows of spraying assemblies each of which includes a housing 15, a tube or elongated tubular member 13 and a spray nozzle 14 arranged at one end of'the tube 13 and directed toward the metal body 5.
  • Each of the tubes 13 is closed at its other end.
  • each of the tubes 13 is axially movable and adapted to extend through or traverse the preferably cylindrical housing 15 which is immovably secured to the support bracket 26 of the supporting arm 11.
  • Each of the housings 15 is sealed at both ends from the tube 13 by a stuffing box which comprises a sleeve 19 having a collar or shoulder portion 18, a threaded nipple 17 and a packing 16.
  • the sleeve 19 is a relatively annular shaped member having external threads on a portion which is adapted to correspond with internal threads in the cylindrical housing 15.
  • the nipple 17 is likewise annular in shape and includes external threads adapted to correspond to internal threads in a portion of the sleeve 19.
  • the packing 16 When properly disposed, the packing 16 extends around the tube 13 and between the end portion of the nipple 17, the inner surface of the sleeve 19, and the shoulder portion. 18. By screwing the nipple 17 into the sleeve 19, an axial force or bracing is exerted on the packing 16 thus causing the packing 16 to be radially braced against the inside surface of the sleeve 19 and the tube 13 to immovably secure the tube 13 in the housing 15 and to seal the connection between the tube 13 and the housing 15. With this connecting means, the axially movable tube 13 may be selectively secured to the housing.15 to permit the selective adjustment of the axial position of the tube 13 and thus the distance between the spray nozzle 14 and the metal body 5.
  • connection 20 Connected with each of the housings 15 is a connection 20, which is associated with the feed line for the medium to be sprayed.
  • the medium to be sprayed is fed into the annular portion 21 (FIG. of the housing through the connection 20.
  • the fluid then flows through the' orifices 22 formed in the surface of the tube 13 and into the interior of the tube 13. From here, the medium is forced through the tube 13 and out through the spray nozzle 14.
  • the orifices 22 are arranged so that they are within the housing 15 and between the stuffing boxes at the ends of the housing 15 for any operative adjustment of the position of the tube As illustrated in FIGS.
  • the spraying assembly support means comprising the part 12, the supporting arm 11 and the support brackets 26 are arranged so that the spraying assemblies are supported in three rows parallel to the axis of the body to be treated with the three rows being angularly staggered around the body to be treated.
  • all of the threaded nipples 17 are initially loosened so that the tubes 13 may be adjusted in a radial direction with respect to the metal body 5.
  • the tight clamping or immovable associations between the housings 15 and the support bracket 26 permits the spray medium to be fed to the individual housing 15 over common non-flexible feed lines secured on the supporting arm 11 which in turn are fed from high pressure hoses.
  • the fixed laying of the feed lines and the relative immobility between the feed lines and the connection 20 insures a minimum danger of leaks even after prolonged use.
  • An improved apparatus for heat treating an axially symmetrical body comprising:
  • a support stand adapted for rotatably supporting the body to be treated
  • each spray assembly including;
  • an elongated tubular member having a spray nozzle at one end and beiirg axially movable through said housing such that a portion of said tubular member is disposed within said housing, said tubular member further having an orifice in the portion disposed within said housing to permit communication between the interior of said housing and the interior of said tubular member,
  • connecting means for sealing the connection between said tubular .member and said housing and for selectively securing said tubular member to said housing to permit the selective adjustment of the axial position of said tubular member and the distance between said spray nozzle and the body to be treated, and
  • tubular member includes a plurality of orifices which are arranged so that they are within said housing for any operative adjustment of the position of said tubular member.
  • said support stand includes a spraying assembly support means for supporting said spraying assemblies in a row parallel to the axis of the body to be treated.
  • said spraying assembly support means is adapted for supporting said spraying assemblies in a plurality of rows angularly staggered around the body to be treated.
