摘要： The invention concerns a method for manufacturing a motor vehicle structural component (1) from an extruded multichamber hollow profile, with the following steps:
a) provision of an extruded profile (2) with at least two precursor hollow chambers (8, 9) which are separated from one another by an inner wall (7), wherein at least one outer wall (3, 4) of at least one precursor hollow chamber (8, 9), in cross-section perpendicularly to the longitudinal extent of the extruded profile (2), has a region (16) with non-linear course,
b) forming of the extruded profile (2) in at least one of its end regions into the motor vehicle structural component (1), wherein at least the region (16) with non-linear course of the at least one outer wall (3, 4) of the at least one precursor hollow chamber (8, 9), with non-linear course in cross-section, is at least partially straightened, with a change in cross-section of the respective precursor hollow chamber (8, 9) into the cross-section of the corresponding hollow chamber (14, 15) of the motor vehicle structural component (1).-

摘要： In a method for the production of a dashboard support for a motor vehicle, a blank is cut from an extruded profile part. The blank is then trimmed and shaped to form a mount which is connected to an end of a crossbeam for allowing subsequent coupling of the crossbeam via the mount to an A-pillar of the motor vehicle.

摘要： A plate heat exchanger has two metal plates brought into abutment, with a solder material between the plates. The plates are heated up to a first temperature. The plates are placed into a mold, the mold surfaces of which have cavities for envisaged channel structures. Channel structures are formed by local internal pressure forming of at least one plate under pressurization by the tool. The plates are heated up to a second temperature. The plates are solder bonded at the abuted surfaces. A plate heat exchanger has two metal plates, wherein channel structures have been formed in at least one plate and the plates are bonded to one another by soldering away from the channel structures. Eutectic microstructures having a longest extent of less than 50 micrometers are formed in the solder layer.

摘要： A motor vehicle sheet metal molding of the invention is produced by hot forming from a metal sheet composed of an aluminum alloy which cannot be precipitation hardened, which contains at least magnesium and optionally manganese in addition to aluminum as alloy component. The motor vehicle sheet metal molding after forming has, at least locally, degrees of deformation which are above the forming limit curve of the aluminum alloy at room temperature. To produce the motor vehicle sheet metal molding, the metal sheet is heated at least locally to a temperature in the range from 200° C. to 400° C. over a period of from 1 to 60 seconds. The heated metal sheet is subsequently placed in a forming tool of a forming press and formed to produce the motor vehicle sheet metal molding.
