Definitions

  • the invention relates to a method for producing rotationally symmetrical bodies, and a device for carrying out the method.
  • EP-A-0 398 455 discloses a method for producing rotationally symmetrical bodies by spraying a molten metal, in which the position of the spray plane is detected by an optically operating transceiver unit.
  • the object of the invention is to achieve an improvement in the known method and the device with a view to a greater constancy of diameter.
  • the invention will be explained in more detail below with reference to the device shown in the figure.
  • the invention is based on a known device in which the melt located in the storage vessel 1 emerges through an opening in the bottom of the storage vessel 1 and is atomized into fine droplets in the nozzle 2.
  • the nozzle 2 is suspended and the pendulum area is indicated by the pendulum angle.
  • This makes it possible to coat an adjustable area on the base 3 and to generate a rotary body by the rotary movement of the base 3.
  • the position of the spray plane 4 and the diameter of the product to be produced are thus defined in the starting position.
  • the drawing shows the base 3 in the lowered position and the spray plane 4 is formed by the free end face of the body 5 already produced.
  • the base 3 is located on a rod 6 on which a transport device 7 engages and causes the rod 6 and thus the base 3 to be lowered.
  • the nozzle 2 and the support 3 are located within a chamber 9 filled with inert gas.
  • the height of the support 3 or the spray level 4 is detected by a transmitter 10 emitting measuring beams in connection with a receiver 11, which are arranged such that the support 3 or the bolt 5 lies in the beam path 12 of the measuring device 10, 11.
  • the procedure in detail is described in DE 39 16 115 A1.
  • a transmitter 14 for generating a light band 16, which is parallel to the base 3, and a receiver 15 with photosensitive cells are arranged opposite the transmitter 14 in the wall of the chamber 9.
  • the transmitter 14 and the receiver 15 are arranged such that they are as close as possible below the spray plane 4 and the light band 16 detects the outer contour 5 ', that is to say the diameter of the body 5.
  • a paired arrangement of transmitters 14 and receivers 15 can be recommended, which can be adjusted by shifting to the respective intended diameter of the body 5 in such a way that they detect opposite sides of the cylindrical body 5 when viewed in longitudinal section. If the temperature of the cylindrical body produced is high enough, ie emits rays due to its temperature, which in the receiver 15, for.
  • the transmitter 14 can be omitted.
  • the one or more receivers 15 are connected to the controller 13.
  • the measured values of the receiver 15, which characterize the diameter of the body 5, are incorporated into the existing control loop or the existing control via the controller 13. This inclusion can take place very early, since the diameter measurement is located just below the spray level.
  • the diameter of the body 5 to be produced is initially given by the distance of the spray plane 4 from the nozzle 2 and the pendulum angle of the nozzle. If, at a defined distance of the spray plane 4, a diameter that is too small or too large compared to the nominal diameter is registered, the position of the spray plane is to be raised or lowered to the extent that it corresponds to the deviation.
  • the diameter determination thus raises or lowers the original target position of the spray plane 4 to the target dimension in the sense of a correction of the diameter, specifically by means of a changed removal speed of the base 3.
