The profile component is subdivided into at least two regions; wherein, a first component region (2) has a ferrite or pearlite/ferrite structure with strength below 850MPa, and a second component region (3) has a martensite structure with strength above 1400MPa, which is characterized in that: the two regions (2, 3) are subdivided along a divisional plane (4) extending in a vertical and/or oblique manner.
Description
Technical field
The utility model relates to as a kind of section bar parts of a bodywork component of power actuated vehicle and the A post with this section bar parts.
Background technology
In serial car construction, normally the load according to them designs bodywork component.In order to realize this point, used to have the most various possible intensity and the sheet material of material structure.
Be known as the B post from EP 1 180 470 A1 and disposed a post member, this B cornice has a following length part that goes up the length part and a high ductility is arranged, this on length partly by a kind of mainly be that martensitic material structure constitutes and has a 1400N/mm
2Above intensity, it mainly is double carbide/pearlitic material structure and 850N/mm that this time length partly has a kind of
2Following intensity.The different plasticity rigidity behavior that causes therefrom in this upper and lower length part has a kind of positive effect to the collision behavior of B post.In addition, in the case, can reduce production costs and weight.
The utility model content
The purpose of this utility model is that above-mentioned section bar parts of the prior art are optimized, and a kind of section bar parts of the bodywork component as power actuated vehicle are provided, so that improve the further application in body construction.
According to the utility model, this purpose realizes that by following 1 and 6 wherein 2-5 is preferred embodiment:
1. as the section bar parts of a bodywork component of power actuated vehicle, these section bar parts are subdivided at least two zones, first component area wherein has a kind of ferritic or pearlitic matrix/ferritic structure of the following intensity of 850MPa, and this second component area has a kind of martensitic material structure and the above intensity of 1400MPa, it is characterized in that these two zones are to segment along a division plane that extends vertically and/or obliquely.
2. above-mentioned 1 described section bar parts is characterized in that, this first component area is by multiple compulsory assemble method, as punching press riveted joint or clamping, assemble with a plurality of adjacent member.
3. above-mentioned 1 described section bar parts is characterized in that, this second component area is to be made by the steel of superhigh intensity.
4. the described section bar parts of one of above-mentioned 1-3 is characterized in that, a transitional region is extended between this first and second component area.
5. the described section bar parts of one of above-mentioned 1-4 is characterized in that, the sheet sheet metal that these section bar parts are weldings.
6. A post has a kind of section bar parts of one of above-mentioned 1-5.
The utility model relates to a kind of section bar parts as the bodywork component of power actuated vehicle, these section bar parts be subdivided on request different vertically and/or the zone that separates obliquely.First area is made of a kind of steel of superhigh intensity, and it has a kind of martensitic material structure and the above intensity of 1400MPa.The second area of a high ductility is made of a kind of ferritic or pearlitic matrix/ferritic material structure, and it has the following intensity of 850MPa.These different intensity area also are used to make it to have by assemble method machinery or compulsory (for example as punching press riveted joint, clamping, or the like) comes the stack-mounted ability, and is used to collide the optimization with weight simultaneously.This ductile zone is suitable for assemble method multiple machinery or compulsory, and the enhancing of section bar parts has been caused in this superhigh intensity zone.
These section bar parts can be made in hot formed process by a kind of direct or indirect production method, and can be through heat-treated so that reach suitable strength rating.In the case, both can be by also can realize the difference of these intensity to the heat treatment of the orientation of single component area by the multiple different steel quality that employing has a sheet sheet metal of welding.
The essence of the present utility model that should see is, compares multiple section bar parts with bigger significantly longitudinal extent with lateral extent and is subdivided into above-mentioned component area by a division plane along their longitudinal extent.
This second area is owing to its ductility can be assembled by multiple compulsory assemble method (as punching press riveted joint or clamping) and a plurality of adjacent components.
This first area can be made by the steel of superhigh intensity, and the rigidity of whole bodywork component is improved.
According to this production method, a transitional region can be extended between this first and second zone.The width of this transitional region can be relatively low, for example when having used the sheet sheet metal of a plurality of weldings.Directional heat in forming process is handled the transitional region that causes as the result's who produces a broad.
In a preferred embodiment, these section bar parts sheet sheet metal that can be a welding.
A preferred application according to section bar parts of the present utility model is the shell spare of conduct on the A post.As finding on direct of travel, so this front area is designed to the zone of a high ductibility, and this Background Region is designed to have superhigh intensity.Consequently, in this front area, can make the A post by the assemble method of routine.In the Background Region of A post, this martensitic material structure provides the enough rigidity that is used to connect door hinge.
Description of drawings
Explain a preferred embodiment of the present utility model in more detail below by accompanying drawing, in the accompanying drawings:
Fig. 1 shows the transparent view of the section bar parts of an A post, and
Fig. 2 shows a lateral plan according to the section bar parts of Fig. 1.
The specific embodiment
Fig. 1 shows the transparent view (not illustrating in greater detail) of the section bar parts of an A post.Section bar parts 1 are subdivided into two component area, and wherein, forepiece zone 2 produces with a kind of soft, ductile quality, and it has greater than 10% breaking elongation and the intensity that is lower than 850MPa.In this zone, might use the assemble method of multiple machinery.As finding on direct of travel F, back part zone 3 is that the quality with a kind of superhigh intensity produces, and it has and is used to bear impact stresses or is used to connect the desired intensity greater than 1400MPa of door hinge.
Division plane 4 extends between two component area 2 and 3 in vertical direction.This division plane 4 can randomly extend with an angle, extends obliquely with it in other words.The extension of division plane 4 between component area 2 and 3 is to select according to the requirement that will satisfy.
Depend on that whether the component area 2 that taken place and 3 vertical separation be owing to use different steel qualities or because the heat treatment in the process that forms forwardly can obtain a bigger or less transitional region 4 of width between part zone 2 and the back part zone 3 in the sheet sheet metal of a welding.
