Definitions

  • the invention further relates to a forming device for producing a component having flanges from sheet metal, in particular a forming device for carrying out a method of the aforementioned type, according to the preamble of claim 5.
  • the flanges of the component produced by forming can also be referred to as wings or flanks.

  • Insufficient dimensional accuracy of the component can lead to further production problems if, after the forming process, component flanges of two components, for example a right and a left sheet metal shell, are welded to one another to form a tubular hollow body, especially butt-welded. Serious dimensional deviations of the component flanges can cause failure of the component or welded connection, especially with butt welding.
  • the JP 2014 4618 A discloses an apparatus for forming high-strength steel blanks into components with a U-shaped cross-sectional profile.
  • the steel blanks clamped between a punch and an upper hold-down device are first formed by an essentially vertical downward movement of die parts, whereupon the die parts are then shifted along inclined sliding surfaces by cams in the direction of the die. Any cracking of the components formed in this way should be compensated for by overbending.

  • the operation of the respective forming press line may have to be stopped in order to achieve the required dimensional accuracy of the components, in order to readjust the forming and / or calibration tools or to replace them with other forming and / or calibration tools to exchange. This is associated with considerable labor and material costs.
