Definitions

  • the invention relates to a device for producing metallic bodies by spraying a nebulized melt of a metal with a housing which at least partially envelops a crucible, a nebulizing device and a material discharge unit, and which has seals for the workpiece holding device and the workpiece.
  • a method and a device for the production of bodies required for its implementation is known, by spraying a atomized melt of a metal or an alloy onto a collecting surface, between which and the spray mist generates a relative movement in the circumferential direction of the body to be produced becomes.
  • the process is carried out under protective gas in a container.
  • the body running from the end of the workpiece holding device passes through a gas seal in the area of the container passage, which is intended to prevent the penetration of oxygen into the interior of the housing.
  • the seal which is only indicated in the figure and is not further described in the patent, is not suitable to solve the problems occurring at this point.
  • air is always sucked in, so that the spray mist is oxidized.
  • solidified metal particles get out of the housing through the passage opening, resulting in high maintenance costs and non-compliance with applicable environmental regulations or standards.
  • a pipe coating device which has a housing which has double-walled passage lock chambers surrounding the pipe which are connected to a device for generating a negative pressure.
  • the invention therefore has set itself the goal of creating a generic device which ensures simple closure of the passage opening for the workpiece holder or the workpiece with simple constructional means.
  • the invention achieves this aim by the characterizing features of the main claim.
  • this includes the constructive mechanical measures with regard to the sealing in the area of the passages, such as the safe setting of the pressure conditions.
  • a hot seal which consists of a contact seal and a protective shield and is rotatably mounted in the passages of the housing.
  • the protective shields are constructed from metallic lamellae, which collect the majority of the metallic particles located in the interior of the housing during spraying. Since this seal rotates with the workpieces, there are no accumulations, especially in the upper area of the workpiece.
  • the contact seal is made up of brush-shaped segments. In order to achieve an axially secure tightness, individual brush segments can be staggered one behind the other will. In order to reduce the wear caused by the axial movement of the workpiece and the thermal loads, guide bolts are proposed which allow the distance or the contact pressure to be made adjustable on the workpiece surface.
  • the contact seal can consist of lamellae. The lamellae are segment-like and are staggered for easy adaptation to different diameters.
  • the blade or brush segments have a blade shape, the side edges of which are guided parallel and the end face of which adapts to the workpiece surface.
  • the blade or brush segments are suspended on guides. Due to the extremely high thermal load and the heavily polluted environment, it is proposed to design these guides in the form of levers with bearings arranged on the head side.
  • the individual segments are guided towards the workpiece by elastic elements. Springs are preferably used, but pneumatic, hydraulic or electrical displacement elements can also be provided.
  • the springs are preferably designed as tension springs.
  • the individual articulation points of the guides on the segments are used as a holder for a tension spring arranged in a ring.
  • the ring with the seals can be rotated by a separate drive.
  • the ring is supported both axially and radially in the passages of the housing.
  • it is provided with openings through which the interior space between the protective shield and the contact seal can be placed in negative pressure. So much volume is sucked off that no oxygen gets into the interior of the spray system and at the same time not too much metallic fog is extracted.
  • the guide pin for the safe distancing of the contact seal either has a rolling element on the head side or is provided with a preferably ceramic protective layer to avoid excessive wear.
  • FIG. 1 shows a spraying device 10 with a housing 11 which is penetrated by a crucible 12 and has a nozzle 13 at which gas supply lines 14 open.
  • the spray jet generated at the nozzle is shown schematically.
  • a material removal 15 is provided in the lower region of the housing 11. Approximately in the middle of the housing 11 there is a passage 16 for a holding device and a passage 17 for a pulling device.
  • the workpiece holder is designated with 18 and the tool pulling device with 19.
  • Seals 20 are arranged in the passages 16 and 17, namely a perforated disk 21 designed as a shield facing the interior of the housing and a perforated disk 22 designed as a contact seal facing outwards.
  • the perforated disks 21 and 22 are provided in a rotatably mounted ring 23, with the bearing has received position number 24.
  • a sealing area is further detailed in FIG.
  • the perforated disk 21 shows lamellar segments 25 which are at least partially overlapping one behind the other.
  • the drain 32 opens into an annular chamber 36, which is formed by the housing 11 and the ring 23 and seals 34 and 35. Openings 29 are provided in the ring 23 so that gas can be sucked out of the space 33 without hindrance.
  • a drive 50 is provided, which is arranged on the housing and drives the ring 23, which in the present example has a ring gear on its forehead.
  • FIG. 3 shows the top view of the ring 23 which can be rotated by the drive 50, specifically in the direction of view of the perforated disk 22, here in the form of elements 26 designed as blades 28.
  • the individual blades are pressed against the workpiece W by a pressing unit 40 , here in the form of springs 43.
  • the blades 28 have grooves 45, in which guide bolts 44 are arranged, which are fastened to a guide 41, here in the form of guide arms 42.
