Definitions

  • the invention relates to a device for coating a hollow body.
  • a material is applied to a carrier component in a layer which is usually only a few ⁇ m in size, in order, for example, to increase its wear resistance or to impart certain properties (for example electrical conductivity) to the component surface.
  • thermal brushing methods in which the coating material is melted and then - regularly atomized by means of a compressed air or other gas stream - and transported to the surface to be coated, are used.
  • thermal coating methods are plasma coating, (high speed) flame spraying and arc wire spraying.
  • the disclosed therein arc spray unit has a burner shaft in the form of a hollow shaft, which is inserted into the cavity to be coated. At the lower end of the burner shaft there is provided a radially directed nozzle through which the droplets of the molten coating material are discharged by means of compressed air supplied through the hollow interior of the burner shaft.
  • a replenishment device with two wire rollers is attached to this.
  • the two wires are led parallel to the longitudinal axis of the burner shaft up to the top.
  • an arc is generated between the two wire ends by means of an electrical high voltage, which melts the wire material.
  • the drops of molten wire are then captured by the flow of compressed air and discharged through the nozzle.
  • the replenishment device ensures a continuous supply of the burner with coating material.
  • the burner shaft is permanently driven in rotation and simultaneously moved linearly in the hollow body. The superposition of the two movements results in a spiral coating course.
  • a disadvantage of the device of DE 19841 617 A1 is the high design complexity associated with the fact that the entire unit of burner shaft and replenishment device must be driven in a rotating manner at high speeds (usually at 100 to 150 revolutions per minute).
  • the invention is therefore based on the object of specifying an improved method and an improved apparatus for coating hollow bodies, wherein at least one disadvantage known from the prior art is reduced.
  • a device should be specified, which allows a structurally simpler structure.
  • the invention is based on the idea that the coating of the hollow body is no longer carried out in a spiral shape by a superimposition of a rotational movement with a linear movement, but in a clocked linear movement.
  • the distribution device for the coating material and the hollow body moving linearly relative to one another become.
  • at least one linear drive is provided according to the invention, by means of which the distributor and / or the hollow body are moved linearly and thereby moved relative to one another. After reaching the stroke end, which is usually due to reaching the end of the linear extent of the surface to be coated, in a subsequent step, the Verteilvorrich- direction relative to the hollow body is rotated by a certain angle, the rotation preferably around the Axis of the previously performed, linear movement takes place.
  • at least one rotary drive for the distributor and / or the hollow body is provided.
  • the surface to be coated can be coated in a second section, for which purpose in turn a linear relative movement of the distributor to the hollow body is carried out. This can be done during the return movement of the distributor relative to the hollow body and thus in the opposite direction to the movement during the coating of the first portion.
  • the distributor can also inactive, that is, without the discharge of coating material to be returned to the output side of the hollow body and the coating of the second section in a subsequent stroke in the same direction as in the previous coating stroke. In this way, if necessary, a coating can be achieved which was carried out exclusively with the same direction of movement.
  • the linear relative movement of the inactive distributor to the hollow body can according to the invention take place before or after the rotational movement.
  • the linear and rotary drive can drive the distributor and / or the hollow body directly or indirectly.
  • it can be provided to provide a fixing device for the hollow body, by means of which the hollow body is securely and accurately positioned. If a linear and / or rotary drive is provided for a movement of the hollow body, this can also be done by moving the fixing device by means of the drive (s), which in turn carries / carry the hollow body positioned thereon.
  • the linear drive is designed as a two- or three-axis linear drive. This makes it possible to move the distributor in one or two further directions in addition to the linear lifting movement, the two or three directions preferably being oriented at right angles to each other.
  • the distance between the distributor and the surface to be coated can be set to the optimum for the coating process, but often a decentralized position of the distributor in the hollow body must be taken into account.
  • the two- or three-axis linear drive may consist of individual elements, which may be spatially and structurally separated from each other, but are preferably controlled by a central control device.
  • Fig. 2 is a diagram showing the movement sequence according to a first embodiment of the invention.
  • Fig. 3 is a diagram showing the movement sequence according to a second embodiment of the invention.
  • a hollow cylinder 1 is shown, the inner surface is sprayed by means of a spray lance 2 with a molten coating material.
  • the structure and operation of the spray lance 2 are basically known from the prior art.
  • the spray lance can be moved by means of a linear drive 3 in the hollow cylinder 1 and moved there along the longitudinal axis of the hollow cylinder 1 over its entire longitudinal extent.
  • the hollow cylinder 1 itself is connected to a rotary drive 4, which drives this invention intermittently rotating, as is apparent from the movement diagrams of FIGS. 2 and 3.
  • FIGS. 2 and 3 show a schematic representation of the movement of the spray lance 2 relative to the hollow body 1 in two alternative embodiments.
  • the linear relative movement (s) along the longitudinal axis of the hollow cylinder and on the abscissa axis of the rotation angle ( ⁇ ) are indicated on the ordinate axis.
  • the inner surface of the hollow cylinder 1 is coated both during the upward and the downward stroke of the spray lance 2. This is symbolized by the arrows at the vertical sections of the curve in the diagram of FIG.
  • the hollow cylinder 1 is rotated by means of the rotary drive 4 by a defined angle ( ⁇ ).
  • ⁇ a further coating stroke of the spray lance 2 is carried out.
  • the inner surface of the hollow body 1 is coated only in an upward stroke.
  • a downward stroke (section of the curve shown in dashed lines) is carried out, in which the spray lance 2 is inactive, ie no coating material is discharged. Only after the completion of the downward stroke is the hollow cylinder 1 rotated by the desired angular amount before a new coating cycle begins.
