Embodiment Construction

[0030] exist figure 1 The panel connection formed by the aluminum panel part 1 and the steel panel part 5 is shown in . In this panel connection, the aluminum panel part 1 is connected to the panel part 5 by means of a steel punch-in element 3 . The production of the aluminum-steel connection shown is carried out in two stages, that is to say first with a deep drawing process in which the steel punching element 3 is extruded into the aluminum sheet part 1 and with a subsequent Resistance spot welding, in which the sheet steel part 5 is welded to the end 7 of the plunger element 3 protruding from the aluminum sheet part 1 .

[0031] as from figure 1 As follows, the aluminum sheet part 1 has a deep-drawn punched recess 9 which protrudes downwards from the base plane of the aluminum sheet part 1 approximately in the shape of a pot. The plunger element 3 is pressed into the punched recess 9 in a form-fitting manner. The punched recess 9 is closed downwards, ie the aluminum mat...

Abstract

The invention relates to a method for connecting at least two sheet metal parts (1, 5), wherein an impressing element is fastened to the first sheet metal part (1) and then the impressing element (3) fastened to the first sheet metal part (1) is welded to the second sheet metal part (5), in particular by spot welding. According to the invention, in order to fasten the impressing element to the first sheet metal part (1), the impressing element (3) is pressed into the material of the first sheet metal part (1) in a deep-drawing direction (T) in a deep-drawing process and enters into a form-locked connection to the first sheet metal part (1) under plastic deformation.

Description

technical field [0001] The invention relates to a method for connecting at least two panels according to the preamble of claim 1 or a panel connection according to claim 10 . Background technique [0002] The use of aluminum-steel connections is known in lightweight construction for automotive applications, in which, for example, an aluminum sheet part is connected to a sheet steel part. To connect the two sheet metal parts, a steel punch-in element can first be pushed into the aluminum sheet parts. The steel punch-in elements pushed into the aluminum sheet part can then be connected to the sheet steel part by spot welding. [0003] A connection method of this type is known from DE 10 2009 035 338 A1, in which the steel punching element can be placed on the aluminum sheet part and can be pushed through it with a given pushing force, whereby punching burrs are produced. The steel punching element has an enlarged rivet head and a rivet shank. After being pushed in, the stee...
