    摘要: The invention relates to a method for heat-forming a work piece (1), in particular a blank made of sheet steel, wherein: the work piece (1) is heated before being formed; the heated work piece (1) is then heat-formed in a forming tool (2), having two tool components (3, 4) in the form of a die (3) and a punch (4), by coming into contact with both tool components (3, 4); and then at least sections of the formed work piece (1) are directly exposed to a gas surrounding the forming tool (2), thereby quenching said work piece. According to the invention, in order to achieve the highest possible fatigue strength with low weight and reduced production costs, after the forming process, at least one tool component part (4.1) of the one tool component (4) is moved away from the side (1a) of the formed work piece (1) facing the tool component (4), while the side (1b) of the formed work piece (1) facing away from said tool component (4) remains entirely in contact with the other tool component (3). The invention also relates to a corresponding forming tool (2) and a corresponding work piece (1).

    摘要: The invention relates to a method for producing a component (5) for a vehicle, having the following steps: -(A) providing a workpiece made of a heat-treatable steel material (2), said workpiece being provided with a zinc-containing coating on both sides, -(B) at least partly heating the workpiece to a temperature above Ac1, -(C) introducing the at least partly heated workpiece into a hot-forming and/or press-hardening tool which comprises at least one punch and at least one die, -(D) closing the tool by moving the punch and/or the die relative to each other and hot-forming and/or press-hardening the workpiece, wherein at least one region of the heated workpiece is cooled in the closed tool such that a hardened microstructure is at least partly formed. The aim of the invention is to provide a method for producing a component for a vehicle, a component for a vehicle, and a use of the component, wherein together with an active corrosion protection, a sufficient component strength in the event of a crash and a sufficient service life expectancy can be ensured in particular with cyclical loading. This is achieved in that the workpiece has a first surface (3) with a smaller layer thickness of the zinc-containing coating than the second surface (4) of the workpiece. The workpiece is introduced into the hot-forming and/or press-hardening tool such that the first surface (3) of the workpiece is positioned on the side which is largely loaded with pressure and/or tension during the component manufacturing process, in particular the tool side which has a largely concave shape.
