Embodiment Construction

[0039] figure 1 A first part 1 and a planar second part 4 are shown intended to be joined together. In this case, the first part 1 is designed as a hollow profile with a crosspiece 2 which forms a centrally oriented central crosspiece of the hollow profile. The upper surface of the hollow profile forms the joining surface 3 and is intended for joining to the second part 4 . Possible positions for the profiled punch rivets are already marked on the second part 4 , wherein these positions are each arranged exactly above the crosspiece 2 of the first part 1 .

[0040] figure 2 is a schematic cross-sectional view of a composite part according to the invention. image 3 More precisely shown by the figure 2 The details are indicated by means of dotted circles. Punch rivets 5 are profiled at the level of the crosspiece 2 from the side of the second part 4 so that the second part 4 is connected to the first part 1 . The crosspiece 2 is used as a die when shaping the rivet 5 . ...

Abstract

A method for producing a punch-riveted connection between a first component and a second component having a flat cross-section, and a composite component that includes the first component and the second component.

Description

technical field [0001] The invention relates to a method for producing a punch riveted connection. The clinched connection is produced between the first part and the second part. The invention also relates to a composite part comprising a first part and a planar second part. Background technique [0002] The joining of two parts by means of punch riveting is known per se. Punch riveting is a riveting method in which it is not necessary to pre-stamp the part. Usage is done for example by solid rivets or semi-tubular rivets. In punch riveting with semi-tubular rivets, the rivet is pushed through a first part and deforms a second part, in particular a sheet metal. During this process, the rivet is expanded and the second part forms the closed head of the rivet. During the riveting operation, the joint is supported on a die that acts as a stand. [0003] In punch riveting of a non-flat first part with a flat second part, although punch rivets can be positioned from the sid...
