Abstract

The disclosure relates to a method for producing a overlapping connection, in which at least two overlapping components are connected to one another via a folded flange, with a first edge of a first component being folded over a second edge of a second component to form the folded flange, along with a body component that includes such an overlapping connection for a vehicle and a stamping tool for such a body component. According to the disclosure at least one connection region is formed on the folded flange, in which the stamping tool stamps the first component through the second component at least one stamping point, with displaced material of the first component passing into the second component and producing a positive connection.

First claim

The invention claimed is:

1. A method comprising:
folding a first edge of a first component over a second edge of a second component to form a folded flange;
forming at least one connection region on the folded flange;
stamping, with a stamping tool, the first component through the second component simultaneously at two adjacent stamping points, wherein displaced material of the first component passes into the second component and produces a positive connection.

2. The method according to claim 1 , wherein a double tip of the stamping tool stamps the two adjacent stamping points simultaneously into the first component in the at least one connection region of the folded flange.

3. The method according to claim 2 , wherein a plurality of connection regions are formed at a predefined distance from one another on the folded flange.

4. The method according to claim 2 , further comprising:
applying an adhesive between the first edge of the first component and the second edge of the second component to form an adhesive bond.

5. The method according to claim 1 , wherein a plurality of connection regions are formed at a predefined distance from one another on the folded flange.

6. The method according to claim 5 , further comprising:
applying an adhesive between the first edge of the first component and the second edge of the second component to form an adhesive bond.

7. The method according to claim 1 , further comprising:
applying an adhesive between the first edge of the first component and the second edge of the second component to form an adhesive bond.

8. The method according to claim 1 , wherein a plurality of connection regions are formed at a predefined distance from one another on the folded flange.

9. The method according to claim 1 , further comprising:
applying an adhesive between the first edge of the first component and the second edge of the second component to form an adhesive bond.
