Definitions

  • the present invention relates to a device for receiving and vertically holding an object to be coated by an electrolysis process according to the preamble of claim 1.
  • a thread can be provided in the end area of a workpiece, in particular when it is a question of piston rods or other elongated workpieces.
  • the object of the present invention is to provide a device by means of which filigree areas of a workpiece, such as a thread in the contact area with a current / voltage source, can be kept free from damage.
  • the present invention is implemented at least when the electrically conductive contact between the device for supplying a workpiece with voltage / current is provided by a plurality of electrically conductive contacts.
  • the plurality of contacts also assume a holding function, which holds the workpiece on the device.
  • the exchange of the workpiece on the holding device can take place automatically, i.e. no operating personnel are required to manually rotate / pull the elongated workpieces into a receiving area of the holding device for the workpiece or out of the receiving area.
  • the purpose of the plurality of conductive holding contacts can be to provide the largest possible contact surface between the holding device and the workpiece. This can prevent the workpiece from burning in the contact area with the holding device if a current flows between the holding device and the workpiece, since only a partial stream of electrons flows through the respective holding device to the workpiece due to the plurality of contact points or contact surfaces between the workpiece and the device. As a result, the respective contact or workpiece temperature in the contact area, i.e. the contact point or the contact surface between the workpiece and the holding contacts, can be reduced when an electrical current is flowing compared to a current flow through a small-area individual contact with the workpiece.
  • the receiving area can also be referred to as a holder.
  • the holding contacts of the holding device are aligned at least in groups and parallel to one another.
  • the workpiece preferably the part introduced into the receiving area, in particular its outer circumference, can be delivered to the individual holding contacts. In principle, this can be done radially, but also tangentially along the workpiece surface. Accordingly, the direction of extension of a holding contact can also take place, for example, laterally past the workpiece and thereby be in contact with the surface of the workpiece.
  • the holding contacts can in principle, starting from several sides of the receiving area, be fed to different sides of the workpiece.
  • the holding contacts can be aligned parallel to one another.
  • the holding contacts on the same side of the workpiece / holder can also be aligned parallel to one another.
  • the springs 20 are aligned in a secant manner with respect to a longitudinal axis of the base body and preferably parallel to one another. If part of a workpiece is inserted into the holder, the loose ends of the springs 20 (holding contacts), which are not connected to the base body 10, are bent / deflected outwards in the direction of the inner wall of the base body 10.
  • the work performed on the spring 20 (holding contacts) as a result can provide a restoring force which presses the spring (holding contacts) against an outer contour of the inserted workpiece area.
  • the surface friction thus provided between the holding contacts and the workpiece can hold the workpiece in the holder. This can also be guaranteed by an additional safety unit such as a magnet (15/35).
  • the individual lamellae can be formed as part of the base body 40, preferably punched out.
  • an insert can also be provided in the holder, which insert can be firmly connected to the holder and can have the lamellae 30.
  • the lamellae can be arranged in several planes one above the other along a longitudinal direction of the holder and / or also be provided in different areas / on different sides with respect to an inserted workpiece. Accordingly, the lamellae 30 can be provided distributed over an entire inner circumference of the receiving area or the holder.
