Abstract (en)
[origin: WO2016066155A1] The invention relates to a method for producing a component by subjecting a sheet bar of steel to a forming process according to the preamble of patent claim 1, which makes it possible for cold-hardened mechanically separated edges of sheet to undergo forming and, independently of the forming into a component, at any desired point in time after the cutting to size of the sheet bar and any further stamping or cutting operations, the edges of sheet that have been cold-hardened by the cutting or punching operations and undergo subsequent cold working in the production of the component are heated to a temperature of at least 600°C, and the time of the temperature exposure is at most 10 seconds.
