Abstract

A method for the individualized adaptation of the shape of components includes providing a basic material for producing the components. Next at least one unifying production method is selected. The components are then produced with a geometrically identical base shape by the unifying production method. Then at least one individualizing production method is selected. Then the shape of the components is adapted to at least two different final shapes by the individualizing production method that is different from the unifying production method. The final shape of each component differs from its basic shape.

First claim

What is claimed is:

1. A method for individually shaping components of a supporting structure, comprising:
a) providing a metal sheet as a basic material for producing the components;
b) producing the components by a unifying production method comprising the steps of pressing and immediately following the pressing, a joining operation, such that the components have a geometrically identical basic shape, wherein the pressing includes producing half shells; and after the half shells are produced, connecting the half shells to each other by the joining operation to create a plurality of junction elements having the geometrically identical basic shape including first and second ends arranged opposite each other on a common longitudinal axis and a third end arranged on a transverse axis relative to the longitudinal axis; and
c) adapting the shape of the junction elements by at least one individualizing production method selected from the group consisting of profile bending with an articulated mandrel, incremental forming, forming with an elastic die, or additive manufacturing, such that the junction elements are transferred from the geometrically identical basic shape into components having one of at least two different final shapes, wherein the junction elements are part of the supporting structure, the junction elements having three connecting points produced from the first, second and third end, respectively, wherein the unifying production method differs from the individualizing production method, and wherein the final shape of each component differs from its basic shape.

2. The method of claim 1 , wherein the basic material for producing the components is one of sheet steel or aluminum sheet.

3. The method of claim 1 , wherein said step of adapting the shape of the junction elements comprises adapting the shape of the junction elements by at least two different individualizing production methods of the group consisting of profile bending, incremental forming, forming with an elastic die, or additive manufacturing.

4. The method of claim 3 , wherein said adapting step includes adapting at least one of the shape or the orientation of at least one connecting point of the junction elements.

5. The method of claim 1 , wherein in said adapting step, the individualizing production method of profile bending is performed as profile bending with an articulated mandrel.

6. The method of claim 1 , further comprising the step of build-up welding the components as the additive manufacturing method.

7. The method of claim 1 , wherein said producing and adapting steps are performed together in one plant.

8. The method of claim 1 wherein at least one connecting point of the connecting points of a first junction element is deformed to have a first angle of inclination relative to the longitudinal axis and at least one connecting point of the connecting points of a second junction element is deformed to have a second angle of inclination relative to the longitudinal axis, the first and second angles of inclination being distinct.

9. The method of claim 1 wherein the junction elements are for a connection of tubes for supporting frameworks.

10. The method of claim 9 wherein the frameworks are one of scaffolding or bridges.

11. The method of claim 1 wherein the junction elements are used in an automotive platform.

12. The method of claim 1 wherein the junction elements are used in ergonomic adaptation of products to body contours.

13. A method for individually shaping components of a supporting structure, comprising:
a) providing a metal sheet as a basic material for producing the components;
b) producing the components by a unifying production method comprising the steps of pressing and immediately following the pressing, a joining operation, such that the components have a geometrically identical basic shape, wherein the pressing includes producing half shells; and after the half shells are produced, connecting the half shells to each other by the joining operation to create a plurality of junction elements having the geometrically identical basic shape including first and second open ends arranged opposite each other on a common longitudinal axis and a third open end arranged on a transverse axis relative to the longitudinal axis;
c) selecting a first junction element from the plurality of junction elements;
d) inserting an articulated mandrel into the first and second open ends of the first junction element;
e) bending the first and second open ends of the first junction element downward and away from the third open end with the articulated mandrel thereby adapting the shape of the first junction element by profile bending such that the first junction element is transferred from the geometrically identical basic shape into a component having a first shape of at least two different final shapes;
f) selecting a second junction element from the plurality of junction elements;
g) inserting the articulated mandrel into the first and second open ends of the second junction element; and
h) bending the first and second open ends of the second junction element downward and away from the third open end with the articulated mandrel thereby adapting the shape of the second junction element by profile bending such that the second junction element is transferred from the geometrically identical basic shape into a component having a second shape of at least two different final shapes, the second shape distinct from the first shape;
wherein the junction elements are part of the supporting structure, the junction elements having three connecting points produced from the first, second and third open end, respectively, wherein the unifying production method differs from the individualizing production method, and wherein the final shape of each component differs from its basic shape.

14. The method of claim 13 wherein the first open end of the first junction element is bent downward to a first angle and the second open end of the first junction element is bent downward to a second angle.

15. The method of claim 14 wherein the first and second angles are equal.

16. The method of claim 14 wherein the first and second angles are distinct.

17. The method of claim 14 wherein the first open end of the second junction element is bent downward to a first angle and the second open end of the second junction element is bent downward to a second angle, wherein at least one of the first and second angles of the first and second open ends of the first junction element is distinct from a corresponding one of the first and second angles of the first and second open ends of the second junction element.

18. A method for individually shaping components of a supporting structure, comprising:
a) providing a metal sheet as a basic material for producing the components;
b) producing the components by a unifying production method comprising the steps of pressing and immediately following the pressing, a joining operation, such that the components have a geometrically identical basic shape, wherein the pressing includes producing half shells; and after the half shells are produced, connecting the half shells to each other by the joining operation to create a plurality of junction elements having the geometrically identical basic shape including first and second open ends arranged opposite each other on a common longitudinal axis and a third open end arranged on a transverse axis relative to the longitudinal axis;
