Abstract

Method for producing individualized components, comprising the steps: casting, in particular die casting, of a basic component, comprising at least one use-specific functional area; assigning the basic component to a use; removing the functional area (s) that are not intended for the assigned use or are.

Description

The present invention relates to a method for producing individualized components, a method for producing vehicles and a cast component, in particular a die-cast component.

A disadvantage associated with casting, in particular with die casting, for example, is the high tool costs. In addition, die-casting is also relatively inflexible, since a shape once produced cannot easily be changed. Likewise, it is not possible to exchange a tool at short notice, for example in a die-casting system, since the set-up times and the associated work are extremely time-consuming and lengthy.

It is therefore an object of the present invention to eliminate the aforementioned disadvantages and to specify a method for producing individualized components and a cast component which make it possible to reduce tool costs and at the same time offer high flexibility in production.

This object is achieved by a method according to claim 1, by a method according to claim 6 and by a cast component according to claim 7. Further advantages and features emerge from the subclaims as well as the description and the attached figures.

• - Gießen, insbesondere Druckgießen, eines Grundbauteils, umfassend zumindest einen verwendungsspezifischen Funktionsbereich;
• - Zuweisen des Grundbauteils einer Verwendung;
• - Entfernen des oder der verwendungsspezifischen Funktionsbereiche, welche(r) nicht für die zugewiesene Verwendung bestimmt ist oder sind.

According to the invention, a method for producing components, in particular individualized components, comprises the steps:

• Casting, in particular die casting, of a basic component, comprising at least one use-specific functional area;
• - Assigning the basic component to a use;
• - Removal of the use-specific functional area (s) which is or are not intended for the assigned use.

The process is particularly advantageous for metallic casting processes, such as, in particular, die casting. In addition, the process can also be used when casting non-metallic materials, such as injection molding. Advantageously, the basic component, comprising the at least one use-specific functional area, enables a very high degree of flexibility in production, since the basic component combines a wide variety of possible uses. The underlying casting mold or tool mold advantageously combines all of the requirements. After the casting, the basic component is individualized as required by post-processing.

• - Entfernen der Funktionsbereiche oder des Funktionsbereichs durch mechanisches Bearbeiten.

The method preferably comprises the step:

• - Removal of the functional areas or the functional area by mechanical processing.

Preferred processes are, for example, cutting processes such as dividing or machining. Functional areas that are not required can advantageously be removed by means of milling, drilling, sawing, grinding, etc.

• - Festlegen verschiedener Verwendungen für das herzustellende Bauteil zum Bestimmen gemeinsamer Funktionsbereiche sowie des zumindest einen verwendungsspezifischen Funktionsbereichs;
• - Integrieren oder Vorhalten der gemeinsamen Funktionsbereiche sowie des zumindest einen verwendungsspezifischen Funktionsbereichs in die Form des Grundbauteils bzw. in das (Guss-)Werkzeug des oder für das Grundbauteil.

According to one embodiment, the method comprises the steps:

• - Specifying different uses for the component to be produced to determine common functional areas and the at least one use-specific functional area;
• - Integrating or providing the common functional areas and the at least one use-specific functional area in the shape of the basic component or in the (casting) tool of or for the basic component.

The basic component advantageously has synergy effects for use in various uses. The mold shape of the basic component advantageously includes all functional surfaces and requirements at the same time. In other words, the functional areas, requirements or functional areas are integrated into the tool shape.

The at least one use-specific functional area is expediently a vehicle-specific functional area. The necessary differentiations, for example due to the vehicle design, connection points for neighboring components, etc., are made through subsequent processing.

• - Bearbeiten gemeinsamer Funktionsbereiche zum Individualisieren des Grundbauteils.

According to one embodiment, the method comprises the step:

• - Editing of common functional areas to individualize the basic component.

The aforementioned processing can include the mechanical processing methods already mentioned. The aforementioned processing can also include removing or ablating the corresponding functional area at least in certain areas.

• - Herstellen von fahrzeugspezifischen Bauteilen nach dem erfindungsgemäßen Verfahren zum Herstellen individualisierter Bauteile;
• - Verwenden der fahrzeugspezifischen Bauteile in unterschiedlichen Fahrzeugtypen.

According to the invention, a method for manufacturing vehicles comprises the steps:

• - Production of vehicle-specific components according to the method according to the invention for producing individualized components;
• - Use of the vehicle-specific components in different vehicle types.

Vehicle types can in particular mean vehicles from different vehicle classes, such as small cars, compact cars, medium-sized cars, luxury cars, SUVs (Sport Utility Vehicles), SAVs (Sport Activity Vehicles), sports cars, etc. In addition, the term “vehicle type” also includes the derivatives within one Vehicle class, e.g. sedan, station wagon, etc.

“Vehicles” means, in particular, motor vehicles, preferably passenger cars. Likewise, the term “vehicles” in the present case also includes commercial vehicles and motorcycles.

The invention is also directed to a cast component, in particular an aluminum die-cast component, which is produced according to the method according to the invention for producing individualized components.

According to a preferred embodiment, the cast component is a structural component, such as, for example, a structural component of a vehicle body or a vehicle frame.

According to one embodiment, the cast component is a strut support or a longitudinal or cross member of a chassis.

Further advantages and features emerge from the following description of cast components with reference to the attached figures.

• 1: eine Ausführungsform eines individualisierten Gussbauteils, erzeugt aus einem Grundbauteil;
• 2: eine weitere Ausführungsform eines individualisierten Gussbauteils, erzeugt aus dem gleichen Grundbauteil.

Show it:

• 1 : an embodiment of an individualized cast component, generated from a basic component;
• 2 : Another embodiment of an individualized cast component, produced from the same basic component.

1 shows an embodiment of a cast component in a perspective illustration 10 , especially a strut support.

the 2 also shows a cast component or a suspension strut support 10 , whereby this was created from the same basic component as that of the 1 . By removing the corresponding use-specific functional areas, the two cast components are 10 but individualized differently. It can be seen that, for example, the one with the reference symbol 20th provided, use-specific functional area for the suspension strut support 10 in the embodiment of 2 was removed. Common functional areas 30th , 31 or. 32 are unprocessed or individualized differently. Such is the common functional area, for example 31 according to the embodiment of 2 with a hole 42 Mistake. The common functional area 32 is partially removed or also provided with a hole. In the 1 is the common functional area 32 reworked by inserting two elongated holes. With just one tool, components can be created that can be used in completely different vehicles.
