Definitions

  • the application relates to a device and a method for cleaning preferably metallic workpieces, in particular for removing solid and / or liquid residues such as sand, chips, lubricants or the like, with an immersion container for a washing liquid and with a holding device for the workpieces to be cleaned, whereby the receiving devices are rotatable about a turntable.
  • Machining residues or impurities are often found on workpieces of the most varied shapes made of the most varied materials or material compositions of metallic or non-metallic type. These adhere both to the outer surface and to the inner wall surfaces of cavities or bores or other recesses. These can be both intermediate products and finished products.
  • Such cleaning systems are used, for example, in the automotive industry to clean complicated workpieces, such as gears or crankshafts.
  • Such devices are known, for example, from DE 35 39 620 C1. This describes a generic device with an immersion container for a washing liquid, in which a lifting frame projecting into the container is provided, on which a workpiece holder can be raised and lowered and can also be rotated about an axis of rotation.
  • the workpiece is moved with an approximately horizontal axis of rotation on this mast into the immersion bath and irradiated with compressed air there, so that a horizontal "water roller” is formed which has a very good cleaning effect.
  • EP 0 360 162 B1 it has been proposed in EP 0 360 162 B1 to use the workpieces in receiving carriers for cleaning, which are arranged in a star shape on a polygonal wheel projecting outwards.
  • the polygonal wheel then rotates the receiving carriers successively into an immersion bath, the cleaning process being carried out by rotating the receiving carriers about an axis perpendicular to the polygonal wheel axis.
  • This known device has also proven very successful.
  • the object of the invention is therefore to propose a generic device and a corresponding method in which the dimensions of the immersion baths can be reduced.
  • the receiving device can be pivoted about an essentially horizontal pivot axis running above the immersion tank between two positions, of which the first arranges the receiving device above the liquid level in the immersion tank and the second the receiving device in the immersion tank arranges substantially perpendicular axis of rotation.
  • this object is achieved in that after the workpiece has been clamped above the liquid surface of the immersion bath, the receiving device with the workpiece is pivoted into the immersion bath about a pivot axis.
  • the size of the work container is on the order of 30%; Achieving a vertical instead of a horizontal water roller also means an energy saving of approximately the same order of magnitude, since the vertical water roller is self-sustaining.
  • the device is characterized in that the immersion bath is followed by an evaporator or maintenance system for wastewater-free operation.
  • this is achieved by completely changing the liquid in the immersion bath after each cleaning process.
  • the swivel angle about the swivel axis is approximately 90 °.
  • nozzles connected to a pressure line for washing liquid and / or air are arranged in the immersion container for the workpiece to flow against the receiving device.
  • Metallic workpieces 1 are preferably to be cleaned in an immersion container 10 which is filled with a washing liquid 16.
  • a receiving device 20 of the device according to the invention is loaded in the swung-out state, ie a position above the immersion container 10, with the washing liquid 16, as shown in FIG. 1, with the workpiece 1 to be cleaned.
  • the workpiece 1 is clamped in the holding device 20. This can happen automatically, for example in the course of a production line in the automotive industry.
  • the holding device 20 together with the clamped workpiece 1 is pivoted downward about the horizontal pivot axis 25 through an angle 27 of approximately 90 °.
  • the workpiece 1 and the receiving device 20 are thus immersed in the washing liquid 16.
  • the workpiece 1 is now located completely below the liquid level 15 in the immersion container 10. This position of the device according to the invention is shown in FIG. 2.
  • the receiving device 20 has an axis of rotation 26 with which the clamped workpiece 1 can be rotated about a longitudinal axis or an axis that is otherwise advantageous in terms of cleaning technology. Simultaneously with the pivoting process or thereafter, a rotation of the receiving device 20 with the clamped workpiece 1 begins about the now approximately vertical axis of rotation 26.
  • 10 nozzles 40 can be arranged in the immersion container for the workpiece 1 to flow against it.
