Definitions

  • the invention relates to a method for producing sheet metal rings, at least have two opposite side faces.
  • sheet metal rings It is known to produce sheet metal rings from sheet templates by punching them out. This process generates significant amounts of waste. Furthermore the side surfaces of the sheet metal rings are often not completely parallel and with the Stamping burrs originating. Sufficient for many applications such sheet metal rings from. However, sheet metal rings are often also desired, whose side surfaces should extend parallel to each other and the have no burrs on their inner and outer edges.
  • the invention has for its object a method for producing To create sheet metal rings with the least possible or even there is no waste in the case of the side surfaces of the sheet metal ring run parallel to each other and avoid burrs on the ring edges becomes.
  • the sheet metal rings are said to have high dimensional accuracy and strength exhibit.
  • the task is solved with a method of the beginning mentioned type according to the invention in that an endless starting material is formed into rings and cut to length, and that the rings in the area of their ends butt welded and then plastically deformed into the Shape of sheet metal rings are transferred. According to the new procedure thus a round material formed into rings, the ends of which are butted together be welded. These rings are then fed to an embossing device and shaped into sheet metal rings. The sides of such a sheet metal ring are perfectly parallel to each other and no burrs occur. Waste completely avoided.
  • the sheet metal ring produced in this way has the advantage that it has a high strength has because the lines of force from the raw material are preserved and in the Find the metal ring again.
  • a wire coil is used for the starting material where the material is drawn off, wound up and cut to length.
  • a rolling and cutting device is used for the rings and their cutting to length. It is advantageous if the rings are cut to length individually.
  • the starting material can optionally be preformed and approximately one have an oval cross-section. This can already be done during the production of the starting material happen or even if the starting material from Coil is withdrawn.
  • the subsequent plastic deformation is carried out at room temperature.
  • the side surfaces of the sheet metal rings are parallel extend to each other.
  • the sheet metal rings can also be used with different Cross-sectional profiles are fitted around in the axial and radial directions to be able to withstand the highest loads with the least amount of material. This is particularly important when the rings are used as sheet metal support bodies provided with a jacket made of polymer material as radial seals are used.
  • the figure shows the individual process steps for the production of the Sheet metal ring 1 shown.
  • the profile wire 3 is withdrawn from the wire coil 2 and wound on a roll 4 with a given diameter and thereby cut to length at the same time.
  • the winding 4 is a rolling and cutting device, in the rings 5 are cut to length.
  • the starting material 3 is on shaped in this way to a still open ring 5.
  • the ring 5 thus formed is butt welded in the area of its ends 6, 7. Ring 5 placed in a welding device and its ends 6, 7 joined together. After butt welding, the ring 5 is inserted into an embossing device 8 and plastically deformed there.
  • the finished sheet metal ring 1 has that in the figure shape shown with the surfaces 9 extending parallel to one another, 10. The entire procedure is done at room temperature and is waste free.
