Abstract

Composite component, in particular for use in vehicle construction, comprising a base material, wherein the base material integrally forms a plurality of, in particular different, components, which are intended for common use.

Description

The present invention relates to a component assembly, in particular for use in vehicle construction, a method for manufacturing, in particular of motor vehicle components, and a use of a component composite for the production of motor vehicle components.

In particular, this is sheet metal parts / components and their production. Sheet metal parts are used in all areas of daily life. In particular, in the production in large quantities, it is customary to assign each sheet metal part its own item number, which controlled due to this part number production and the entire logistics chain. This requires a considerable control, administrative and logistics costs, which leads among other things to high production costs. Another problem is that a complete tool is required for each sheet-metal part. In the production of individual sheet metal parts also often falls to much waste, which is no longer usable. The same applies to corresponding components made of plastic (s) or composite material (s).

It is therefore an object of the present invention to provide a component assembly, a method for manufacturing and a use of a component composite, which eliminate the aforementioned disadvantages and in particular contribute to a cost reduction.

This object is achieved by a component assembly according to claim 1, by a method according to claim 9 and by a use according to claim 15. Further advantages and features will become apparent from the dependent claims and the description and the accompanying figures.

According to the invention, a component assembly, in particular for use in (automotive) vehicle construction, comprises a base material, for example a metal sheet, wherein the base material integrally forms or forms a multiplicity of, preferably different components, and wherein the components are intended for common use are. In other words, the components z. Conveniently, a preferably substantially flat or plate-shaped base material, such as a metal sheet or a sheet metal blank, is provided, which has a plurality of components, for example at least two, preferably three, four, five or six, seven, eight, nine, ten or more components. In this case, it is particularly preferred for these to be produced integrally and connected to one another in an integral manner, in other words, to one another, this connection being or are formed by the base material itself, that is to say integrally or integrally. The component composite is therefore a unit which can be handled as a whole. The invention is not limited to the body and / or vehicle but can also, for example, in the field of production of household appliances (refrigerators, stoves, washing machines, etc.), just to name another example, use.

The common use is to be understood both in that the components z. B. be used for a common assembly as well as in terms of time, namely that the components are used or used at a substantially simultaneous time in the context of a manufacturing process. In that sense, sharing can be defined both in terms of time and function. The advantage is that the component assembly provides all (individual) components / components that are needed for the production or manufacture of an assembly, wherein the assembly is a part that consists of the individual components / components accordingly this is joined together. The logistics costs are reduced enormously.

Under a component is z. B. a plastic or sheet metal part, such as a cover or a wall component of a housing of a food processor, a Türverstrebung a motor vehicle, corresponding hinges, suspension components, etc. The assembly then includes accordingly the entire housing (the example mentioned kitchen machine) or ( entire) door of the motor vehicle. It is understood that the component composite does not have to comprise or comprise all individual parts, components or components from which the (final) assembly is actually constructed, but preferably at least those of the same material (and possibly also the same wall thickness).

According to one embodiment, at least one component is machined and / or shaped and / or manufactured by a forming process. Examples include, for example, forging, driving, indenting, rolling, folding, deep drawing, beading, flanging, straightening, bending, stretching and / or upsetting. According to one embodiment, for example, further or alternative manufacturing methods are separating, joining and / or coating. Also, at least partially, change of material properties is possible.

According to one embodiment, the base material is a sheet of a metal such as steel or aluminum, for example with a wall thickness in a range of about 0.8 to 5 mm. Under a sheet is in the present case, however, for example, to understand an extruded profile, so that the sheet can be an elongated body whose length is significantly greater than its width. The aforementioned flat sheet is, for example, substantially rectangular, for example, square or rectangular, shaped, the side lengths, depending on the application, can be in a range of about 50 to 300 cm.

Alternatively, the base material can also be a plastic material, in particular a fiber-reinforced plastic material, in other words a composite material. Also material combinations are conceivable.

Preferably, the component assembly is machined by a tool or is produced by a tool that can shape / form the various components in one operation. A tool geometry thus advantageously includes the geometry of the various components.

Preferably, several components in a single operation, in particular in a forming operation, ie by a forming process, processed / molded / manufactured. So are particularly preferred with a tool simultaneously several components in z. B. the sheet formable or producible. The processing is performed with advantage in such a way that the component composite remains as such, in other words no "individual parts" arise. In the case of a plastic material or a composite z. For example, a mold is used which is designed to form a plurality of components.

According to one embodiment, at least two components are formed differently / shaped / manufactured or also machined.

The fact that at least two components are formed or shaped differently, in particular aims that they are advantageously designed for use in one or the common assembly. Conveniently, the component assembly comprises a plurality of components or individual parts, wherein the components contained are each provided for the production of a common assembly or assembly.

In addition, the components can also be arranged in such a way that they are used, for example, only locally or temporally simultaneously. This means that the component assembly is advantageously transported as a unit to a specific position / point in the manufacturing process and "separated / separated" / separated, so that the components are essentially (time) the same, in other words, processed without a further intermediate storage can. This reduces the logistics and storage costs enormously.

Conveniently, the components are designed or compiled so that they can be used at least partially simultaneously and / or assembled or joined. Preferably, at least some, preferably all, components are assigned to a common assembly. In the assembly, it may be z. Example, to act a door of a motor vehicle or a housing of a food processor, which are each composed of a plurality of individual components / components. The component composite advantageously includes this plurality of (different) components, so that based on the component composite, for example, the entire door or the entire housing can be assembled, at least as far as the parts of the same material. The entire logistics effort is thus reduced enormously, since, for example, a certain assembly can be manufactured on the basis of a corresponding component composite. It is therefore not necessary to bring the different parts from different areas of production, to coordinate etc. The parts required for the respective modules are space-saving and ideally combined in the corresponding component group.

Advantageously, the base material is divided into processing zones, wherein the components are or are formed in the processing zones. Preferably, a processing zone is designed / dimensioned for at least one component.

According to one embodiment, the components are arranged adjacent to each other, for example substantially immediately adjacent to one another. Conveniently, the components touch or are connected to each other via line and / or point contacts. These line and / or point contacts can be designed such that the separation of the components is / is facilitated. For this purpose, the line and / or point contacts z. B. corresponding predetermined breaking points, for example in the form of perforations, impressions, etc. on.

According to one embodiment, the components are connected by tabs and / or webs. Advantageously, the tabs or webs are also provided by the base material or the processing zones, d. H. a part of the processing zone is formed into one component, while another part forms a later tab or web.

Appropriately, the aforementioned tabs and / or webs or the line and / or point contacts in the context of machining of the components, if possible, formed with. Optionally, it is also possible to manufacture them in a separate operation. It is also not excluded, possibly in the components existing openings or to use holes to later (additional) reinforcements, straps or bars attach / fasten, etc., if necessary, the component composite as a unit to reinforce or stiffen or even produce. Also, the aforementioned tabs and / or webs are advantageously in turn connected via line and / or point contacts with the respective components.

It is particularly preferred in this context, in particular against the background of the best possible material utilization, that in any recesses or recesses of a component, one or more processing zones are formed for further components or one or more further components are positioned. Conveniently, therefore, at least one component has a recess or a recess or forms it, wherein in the region of the recess or the recess a processing zone is formed, in other words one or more (other) components are formed. Thus, the sheet metal base material can be exploited in an ideal manner and any wastage can be reduced to a minimum.

According to one embodiment, the component composite has a main component which, for example, comprises about 60 to 90% of a base area of the base material. Conveniently, it is an irregularly shaped component, which would normally lead to much waste or material waste. Conveniently, a plurality of components are now arranged in any recesses, recesses, undercuts of the main component, whereby the material utilization can be optimized or maximized.

According to one embodiment, the components have the same wall thickness. Conveniently, the components of the composite component are also compiled to the effect that they have a same wall thickness. Here, too, the sheet preferably has a constant wall thickness.

Alternatively, the base material or sheet, which forms the plurality of components, also at least partially have a different wall thickness, thereby a component composite is made possible, which comprises components having different wall thicknesses. Conveniently, the corresponding tool for shaping the composite component, designed to process the sheet or the base material with the different wall thicknesses in one step.

Alternatively and / or additionally, the production of the various components can also take place in several steps. A sequence could, for example, be realized as follows: forming or deep drawing, subsequent at least regional separation, for example for producing or introducing bores, and subsequent cutting for cutting or shaping an outer contour of the components or of webs, etc.
