Abstract
The invention discloses a high-strength sheet metal component used for an automobile and belongs to the technical field of automobile materials. The back of a sheet body is provided with a runner groove which projects outwards, the two side walls of the runner groove are provided with arc-shaped structures, the depth of the runner groove is at least one centimeter, and the width of the runner groove is at least 0.5 centimeter; and a reinforcing body is fixedly arranged in the runner groove, the cross section of the reinforcing body is triangular, and the reinforcing body consists of the following components in parts by mass: 6-12 parts of aluminum alloy, 45-55 parts of iron, 0.1-0.2 part of carbon, 0.6-1.2 parts of chromium and 0.2-0.4 part of silicon. The problem that the strength of the existing sheet metal material is low is solved.
Description
Technical field
The present invention relates to the technical field of automotive material, in particular to a kind of high intensity sheet metal component for automobile.
Background technology
Panel beating is a kind of comprehensive cold machining process for sheet metal (generally in below 6mm), including cutting, rush/cut/answer
Close, folding, welding, riveting, splicing, shaping (such as body of a motor car).Its significant feature is exactly Same Part consistency of thickness, is passed through
The product that sheet metal process is processed is called sheet metal component.Vehicle frame and car door of automobile etc. have all selected sheet metal component, usual sheet metal component
Face exposure outside, constitutes the outer surface of automobile, the back side of sheet metal component inwardly, or one side inwardly is not easy to see positioned at people
The position (position outside driver's cabin) for observing, or being coated by interior trim within driver's cabin.Automobile metal plate work
Some places are easier to be clashed into, therefore need to reinforce some places, but because the thickness of sheet metal component it is consistent,
During shaping, it is impossible to form thicker structure at the place of needing reinforcement.
The content of the invention
It is an object of the invention to provide it is a kind of for the high intensity sheet metal component of automobile with reach improve automobile sheet metal component
The purpose of intensity, solves the problems, such as above-mentioned.
To realize the object of the invention, the technical scheme for adopting for：A kind of high intensity sheet metal component for automobile, its feature exists
In the back side of the plate body is provided with the flow path groove of outwardly convex, and the two side of flow path groove is set to arc shape structure, the depth of flow path groove
Degree is at least 1 centimetre, and the width of flow path groove is at least 0.5 centimetre；It is fixed with reinforcing body in the flow path groove, reinforcing body cuts
Face is triangular in shape, and reinforcing body is made up of the mass fraction of following component：Aluminium alloy 6-12 parts, iron 45-55 parts, carbon 0.1-0.2 parts,
Chromium 0.6-1.2 parts, silicon 0.2-0.4 parts.
Further, the reinforcing body is made up of the mass fraction of following component：8 parts of aluminium alloy, 50 parts of iron, carbon 0.15
Part, 0.8 part of chromium, 0.3 part of silicon.
Using the invention has the advantages that：
1. it is provided with plate body for the flow path groove of cast reinforced body, by the way that the reinforcing body of molten condition is cast in into runner
In groove, reinforcing body is combined closely with flow path groove, and relative to by reinforcement or reinforcing plate the plate body back side, this kind of mode are welded on one by one
It is time-consuming shorter, in hgher efficiency, and the combination of reinforcing member and flow path groove is also more firmly, can meet the requirement at reinforcing；
2. reinforcing body is made up of the rational proportioning of metal material, even if deforming, also can be replied by sheet metal process, plus
Contain more iron in solid, iron is most useful on the earth, most inexpensive, most abundant metal, and have good ductility and resist
Impact property；Also contain aluminium alloy in reinforcing body, aluminium alloy quality is light, and intensity is higher, and plasticity is good；Chromium and silicon can be carried significantly
High intensity, hardness wearability.
Description of the drawings
Fig. 1 is a kind of structural representation of high intensity sheet metal component for automobile that the present invention is provided.
Specific embodiment
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
Fig. 1 illustrates a kind of structural representation of high intensity sheet metal component for automobile of present invention offer, and its feature exists
In the back side of the plate body is provided with the flow path groove of outwardly convex, and the two side of flow path groove is set to arc shape structure, the depth of flow path groove
Degree is at least 1 centimetre, and the width of flow path groove is at least 0.5 centimetre；It is fixed with reinforcing body in the flow path groove, reinforcing body cuts
Face is triangular in shape, and reinforcing body is made up of the mass fraction of following component：Aluminium alloy 6-12 parts, iron 45-55 parts, carbon 0.1-0.2 parts,
Chromium 0.6-1.2 parts, silicon 0.2-0.4 parts.
Used as preferred scheme, the reinforcing body is made up of the mass fraction of following component：8 parts of aluminium alloy, 50 parts of iron, carbon
0.15 part, 0.8 part of chromium, 0.3 part of silicon；
It is made up of the mass fraction of following component as another kind of reinforcing body：11 parts of aluminium alloy, 54 parts of iron, 0.19 part of carbon,
1.1 parts of chromium, 0.4 part of silicon.
1st, the reinforcing body 3 in the various embodiments described above all possesses good impact strength, corrosion resistance and its rational bullet
Property modulus, (, without in the case of reinforcing body 3, shock resistance is strong for plate body 1 greatly to improve the impact strength of automobile metal plate work
Degree is about 650MPa, so as to preferably be reinforced to plate body 1.
2nd, the casting time of reinforcing body 3 is shorter, it is only necessary to 5 minutes, and welds an equal amount of securing plate, and weld interval is at least
For half an hour, which can effectively improve efficiency.And from the form cast than the form with welding, plate body 1 and reinforcing body 3
Combination more firmly, because to large-area welding, commonly using spot welding, the bonding area of spot welding is less；And cast equivalent to
Full weld in welding, the area of welding is larger, and plate body 1 can be adequately bonded with reinforcing body 3.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
