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.

摘要： The invention relates to a supporting core (1) for using in a device for shaping plates to form a structured hollow profiled element comprising a plurality of interconnected supporting members (2), and to a method for producing structured hollow profiled elements from a plate. The aim of the invention is to provide a supporting core (1) for using in the production of structured hollow profiled elements, which ensures an all-over support of the plate, and thereby enables the production of hollow profiled elements with a variable cross-section or a curved form. To this end, when the individual supporting members (2) are pushed together, at least part of the surface thereof forms the inner contour of the hollow profiled element to be produced and they are interconnected by means of coupling elements (4). The coupling elements (4) allow the supporting members to be separated, said supporting members (2) being interconnected in an articulated manner in the separated position thereof.

摘要： The invention relates to a method for at least partially removing coatings from metal blanks (5) coated on one or both sides, in areas which have a main extension direction, wherein the areas from which the coating is to be removed can extend straight or curved in the main extension direction. The invention further relates to a device (1) for at least partially removing coatings from a coated blank (5) for performing the method according to the invention. The aim of providing the simplest possible method and the simplest possible device (1), by means of which device the coating of a blank (5) can be removed effectively and in a cost-saving manner, in one pass if possible, is solved for a method in that the blank (5) is laid onto a blank support (4) of a press (1), and during the closing movement of the press (1) at least one scraping knife (7-10) removes the coating of the blank (5), preferably completely, by scraping substantially perpendicularly to the main extension direction of the area of the blank (5) from which the coating is to be removed.

摘要： The invention relates to a method for producing hollow profiles having a longitudinal flange, wherein a blank disposed between a punch and a first die is preformed into a U-profile having a first limb and a second limb by driving a punch into a first die, and wherein the U-profile is formed into an O-profile having a longitudinal flange by means of a second die. The aim of disclosing a reliable method for producing hollow profiles having a longitudinal flange and allowing better control of the dimensions and shape of the longitudinal flange is achieved in that a longitudinal flange limb segment is formed in at least the first limb when preforming the blank into the U-profile, and the longitudinal flange limb segment is formed into a part of the longitudinal flange while substantially retaining the shape thereof during the forming of the U-profile into an O-profile.

摘要： The invention relates to a process for producing a hollow body from metal, said hollow body having at least one first axial portion with a first cross-sectional area and a second axial portion with a second cross-sectional area, and in which the two axial portions of the hollow body are connected to one another by means of a shape transition running in the axial direction, wherein a preform body having at least one transition region which extends in the axial direction of the hollow body to be produced and is arranged between the first axial portion and the second axial portion is produced, wherein, in the transition region, the cross-sectional area of the preform body preferably continuously changes from the cross-sectional area of the first axial portion into the cross-sectional area of the second axial portion, the preform body (1) is accommodated in a die (5), wherein the die (5) has the final external shape of the hollow body to be produced, a shaping mandrel (7) is inserted into the preform body (1), wherein the shaping mandrel (7) has the internal shape of the hollow body to be produced, and an axial movement of the shaping mandrel (7) upsets the preform body (1) in the die (5) into the final shape of the hollow body. In addition, the invention relates to an apparatus for carrying out the process.
