But, require that the material used is the least possible, for instance to realize favourable cost structure at manufacture view simultaneously. But, processed by those known rolling formings, the further saving of material can not be realized, because harder material, especially high-strength material are only capable of rolling forming under some restrictive conditions, after during during manufacture or immediately manufacturing, less material wall thickness can cause elastic return to increase. For this, commonly used high strength steel in the mill, described high strength steel has the wall thickness of the tensile strength reaching 800MPa and at least 1.6mm. At least at the structural member of the armchair structure for motor vehicles, especially in the structural member of seat rail for vehicle, so far but without making semi-finished product formula goods have less wall thickness and/or bigger tensile strength.

In this approach, according to the present invention, semi-finished product formula plate-shaped products is that rolling forming processes and controlled temperature, and wherein temperature controls to occur in local, especially in the shaped region of semi-finished product formula goods, the pending shaping operation of described shaped region. Temperature controls to comprise heating and/or cooling, and preferably takes place before shaped half-product formula goods or period. The section bar processed in this way or structure member is made then to have higher load-carrying ability than those section bars or structure member not controlled temperature.
Shape according to section bar to be manufactured or parts, rolling forming processes and occurs with predetermined forming sequence. In this article, term " forming sequence " refers to the order that each shaped region is processed, be namely formed, and wherein forming sequence is produced by section bar to be produced or structural member and radius of corner thereof. Therefore each section bar manufactured by rolling forming includes the forming sequence determined during rolling forming processes. In order to realize rolling or shape and temperature controlled as far as possible directly association in time, shaped region is one after the other controlled temperature in the forming sequence that rolling forming processes. In this way, the energy input needed for processing procedure can be reduced on the one hand, the load acting on during manufacture can being reduced on the other hand on the semi-finished product formula goods of pending shaping operation or acting on component end item.
In this processing procedure, local heating occurs preferably in the banding shaped region of semi-finished product formula goods, described banding shaped region along rolling forming direction arrange so that shape or processing procedure in stress or experience deformation shaped region controlled temperature, especially heated.
Embodiment according to method or design, it can be advantageous to application sensing heating or carry out energy input by laser emission. The implementation that both is relevant to method all provides the option of heating semi-finished product formula goods, it is intended that in targeted mode, described semi-finished product formula goods are formed operation under given conditions and therefore in shaped region. In a preferred embodiment, laser emission is occurred by fibre laser device.
Semi-finished product formula goods can also be made after such shaping to harden, i.e. the quenching when using coolant (such as oil groove etc.). The parts produced by this way can include intensity that is higher and that therefore improve, particularly in previous thermoforming region, local or radius of corner region. In this processing procedure, these thermoforming regions, local or radius of corner region can shape or between rolling forming, period or be heated afterwards.
In addition, this will cause that another application of the invention option, described application of option include being produced parts to be manufactured or structural member by normally used more soft material, and described more soft material is generally speaking more economically, especially somewhat softer steel, described steel is hardened process by quenching subsequently. Additionally, quenching or hardening after partial temperature control, especially local heating energy and rolling forming occur in combination. Such as can improving the load-carrying ability of more soft material by this way, described more soft material (such as manganese-boron steel) is easier to shape, and the section bar therefore manufactured by these materials also can be further optimized.
Parts, the structure member being particularly useful for the armchair structure of motor vehicles have tabular section, described tabular section is oriented relative to one another to an angle, and it is connected with each other by being designed at least one shaped region of radius of corner, according to the present invention, shaped region experience makes the temperature control that material behavior changes process, and includes the change of the microstructure produced owing to temperature control processes. Therefore, shaped region is different from tabular section for material structure, also different from the miscellaneous part not being temperature controlled and processed by rolling forming, but, described shaped region has as hereinbefore or than aforementioned higher intensity.
Especially, parts are made by high strength steel or by high-intensity aluminium, usually, they can additionally by rolling forming method or rolling forming disposal methods, and especially for the parts being formed from steel, intensity is higher than especially 1,000MPa or more or 1,200MPa or more.Therefore, parts constructed in accordance can preferably have 1.5mm or even 1.4mm or 1.3mm or less than all aforesaid wall thickness.
