Definitions

  • the invention relates to a process for producing a one-piece light metal wheel from a hardenable wrought aluminum alloy by flow pressing or rolling from a blank, in which the flow pressing or rolling to the finished product is carried out in the hot state and in which solution annealing is carried out at temperatures of approximately 530 ° C. depending on the type of alloy followed by quenching and heat hardening at 150 ° to 200 ° C, and in particular its use for producing a one-piece light metal wheel from an alloy of the type AlMgSi.
  • flange blanks are used, in which the flange, which is approximately rectangular in cross-section, is split radially and then the rim base is rolled out, or so-called pot blanks in which the rim base is also rolled out with support from the correspondingly shaped edge region becomes.
  • the blanks are heated to a temperature range of 150 ° to 250 ° C. in a known method. After completion, solution annealing takes place at temperatures of approximately 530 ° C., depending on the type of alloy, and heat hardening at 150 ° to 200 ° C.
  • the purpose of the invention is to largely avoid warping of the finished rolled part and to reduce the energy expenditure in a method of the type mentioned at the beginning.
  • thermoset This object of the invention is achieved with a method of the type mentioned, which is characterized in that, after solution annealing, the blank is quenched in a controlled manner to about 200 ° C., depending on the alloy type, flow-pressed or rolled at this temperature, avoiding excessive heating to the finished product, and then "is thermoset.
  • the blank is split and then flow-pressed or rolled into a finished pot.
  • the rolling out of the blank after the controlled quenching from the solution annealing temperature also leads to improved material structure and thus also to improved use properties.
  • the heat curing then takes place in a known manner.
  • the invention also includes the proposal to carry out quenching after solution annealing at high quenching speed using water showers with a defined amount of water and water temperature. Good mechanical properties are achieved in this way. However, it is also possible to quench several blanks in suitable racks using appropriate water sprinkling.
  • Such a method is preferably used to produce a one-piece light metal wheel from an alloy of the AlMgSi type.
  • the so-called turning allowance for the rim base can be significantly reduced. Concentricity and imbalance are reduced.
