Embodiment Construction

[0019] figure 1 The component 1 shown in is formed into a profile by roll forming and is generally produced by roll forming. This part 1 comprises several plate-shaped sections 3 which are produced substantially unchanged from semi-finished plate-shaped products. The individual plate-like sections 3 are connected to one another in the radial region of the component 1 by hatched forming regions 4 a , 4 b , 4 c , 4 d which are formed during the flow forming process. In particular, these forming regions 4 a , 4 b , 4 c , 4 d present significant problems in terms of formability when forming high strength steels especially with Rm > 800 MPa, especially during the formation of closely adjacent fillet radii.

[0020] figure 2 shows the basic development of the section of part 1 figure 2 . Such as figure 1 In the example shown, the shaped regions 4 a , 4 b , 4 c , 4 d shown shaded are demarcated by corresponding lines and each extend in the direction of roll forming. These for...

Abstract

The invention relates to a method for the roll-forming of profiles or structural parts from semifinished sheet-like products, in particular from metallic materials, in particular from steel sheet or aluminium. For this, the semifinished sheet-like product is adjusted in its temperature, the adjustment of the temperature taking place locally, in particular in forming regions of the semifinished product that are intended to undergo a forming operation. Furthermore, the invention relates to a component preferably produced by using this method, in particular a structural part for a seat structure of a motor vehicle, in particular a vehicle seat rail that can be adjusted forwards and backwards to adjust the seat, and to a roll-forming device for carrying out the method.

Description

technical field [0001] The invention relates to a method for roll forming a semi-finished plate-shaped product, especially a metal material, especially a steel plate or aluminum, into a profile or a structural part. Furthermore, the invention relates to a component preferably produced by such a method, in particular to a structural part for a seat structure of a motor vehicle, and also to a roll forming device for carrying out the method. Background technique [0002] These profiles or structural elements require the materials used to have a specific strength, so that most structural components have sufficient load carrying capacity. At the same time, however, it is required that as little material as possible be used, for example in order to achieve an advantageous cost structure in terms of production. However, with known flow forming processes, no further savings in material can be achieved, since harder materials, especially high strength materials, can only be flow for...
