Problems solved by technology

However, the problem arises with this external reinforcement that for this there must be space outside the hollow profile
In addition, this external reinforcement is also accompanied by significantly greater weight and its performance is often unsatisfactory
Finally, due to these external connections also negatively affect the formation of creases in the event of a crash, since the carrier cannot form creases in the reinforcement area

Embodiment Construction

[0049] figure 1 The initial hollow profile 1 for the inventive hollow profile is shown, which is configured as a two-chamber hollow profile. Here too, the initial hollow profile 1 is designed as a rectangular hollow profile with a first side wall 18 and a second side wall 19 as well as a positioning wall 2 and an introduction wall 4 connected to the side walls 18 , 19 . In addition, an intermediate wall 5 between the side walls 18 and 19 is arranged inside the initial hollow profile 1 . figure 1 The initial hollow profile 1 is shown in a perspective view from above, so that the positioning opening 3 for the positioning element 8 of the support element 7 made in the positioning wall 2 can be seen.

[0050] figure 2 Now shown in a perspective view from above figure 1 The initial hollow profile 1. An introduction opening 6 can be seen here, which is arranged in the introduction wall 4 .

Abstract

The invention relates to a method for producing a hollow profile with the following method steps: a) providing an initial hollow profile (1) with an introduction wall (4) and optionally an introduction opening (6) in at least one intermediate wall (5) ); b) providing a support element (7) with a pin element (9), an active element (10) and a support wall (11) arranged between the pin element (9) and the longitudinal side wall (12) c) pass the support element (7) through the introduction opening (6) until the support wall (11) is positioned in the initial hollow profile (1); d) apply a tool to the action element (10); e) Turn the support element (7) with the tool until the area (13) of the longitudinal side wall (12) comes into contact with the inner wall (14) of the initial hollow profile (1); f) the area (13) of the longitudinal side wall (12) It is connected to the initial hollow profile (1) through the inner wall (14).

Description

technical field [0001] The invention relates to a method for producing a hollow profile with a support element. Background technique [0002] Hollow profiles are used in a variety of ways in the automotive sector, especially as structural or running gear components, which must be high-strength on the one hand, especially as longitudinal and / or transverse load-carrying elements in the interior of the vehicle body, but On the other hand, it can also be loaded dynamically. In this case, dynamic loads arise in particular locally during the coupling to the chassis components. [0003] Such hollow profiles are increasingly being processed by extrusion. In order to increase the rigidity in the region of the coupling to the components, such hollow profiles configured as structural components usually have support elements made of metal in their cavities, possibly perpendicular to their longitudinal extension. Such a support element is usually designed as a continuous cylindrical s...
