Definitions

  • the invention relates to a roll-profiled component, in particular for a motor vehicle, and to a method for producing such a component.
  • the roll-profiled component is in particular a structural part or body part of a motor vehicle.
  • a roll-profiled component according to the preamble of claim 1 is known from DE 197 20 109 A1 known.
  • the object of the invention is to propose a roll-profiled component which is variable in height, and to provide a method for its production.
  • a roll-profiled component having the features of claim 1.
  • the roll-profiled component which is in particular a structural part or body part of a motor vehicle, is made of two individual parts which have a variable height along their longitudinal axis and which are interconnected. It is possible to make the component from more than two parts.
  • the connection of the individual parts can be done by welding, in particular by laser welding.
  • one or both items are cropped at its inner edge.
  • the items are connected to each other at the optionally trimmed inner edges.
  • the items have a horizontal portion and a vertical portion. It is possible that the items have several horizontal sections. Instead or in addition, the items may have multiple vertical sections.
  • a horizontal section is understood to mean a section that extends in the direction of the width of the component or part.
  • a vertical section is understood to mean a section that extends in the direction of the height of the item or of the component. It is advantageous if the item has a Z-profile with a vertical and two horizontal sections. It may also be advantageous that the item has an L-profile with a horizontal and a vertical portion. Other profile shapes are possible.
  • a further advantageous development is characterized in that the height of the individual parts or the vertical portions of the items in the middle is greater than at the ends. This is particularly advantageous when the component is subjected to bending. Preferably, the component or item in the middle of the greatest height.
  • the individual parts have a variable width along their longitudinal axis.
  • the problem underlying the invention is further achieved by a method having the features of claim 5.
  • the method for producing a component by roll profiling in particular a component according to the invention, is characterized in that two individual parts with a variable over its longitudinal axis Height can be produced. It can also be made more than two items. The items are manufactured by roll profiling.
  • One or both or all parts are trimmed at their inner edge.
  • the inner edges are preferably trimmed in a straight line. However, it is also possible not to cut the inner edges straight.
  • the individual parts are connected to each other at their inner edges.
  • the connection is preferably by welding, in particular by laser welding.
  • An advantageous development is characterized in that the items are made with a variable over its longitudinal axis width.
  • a first item 1 and a second item 2 are shown, both of which have been made by roll profiling from a rectangular, flat sheet metal strip.
  • the first item 1 has a Z-shaped cross-section, the a lower horizontal portion 3, a vertical portion 4 and an upper horizontal portion 5 consists.
  • the lower horizontal section 3 has the same width over the longitudinal axis of the first item 1.
  • the vertical section 4 has a variable height over the longitudinal axis of the first item 1.
  • the height of the vertical portion 4 is lowest at the ends of the first item 1. It climbs towards the middle and reaches the highest altitude in the middle.
  • the height of the vertical section 4 follows a substantially S-shaped course. It is larger in the middle than at the ends.
  • This embodiment is particularly advantageous when the component is subjected to bending, since the bending moment in the middle of the component is greatest and there the greater height of the vertical portions of the bending moment opposes the greatest resistance.
  • the inner edge 6 at the end of the upper horizontal portion 5 does not form a straight line.
  • more material for the vertical portion 4 is required in the middle of the first item 1, so that there is less material available for the upper horizontal section 5.
  • the width of the upper horizontal portion 5 is thus lower in the middle of the first item 1 than at the ends.
  • the second item 2 is symmetrical to the first item 1 and includes the corresponding components 3 ', 4', 5 'and 6'.
  • the comments on the first item 1 apply in a corresponding manner for the second item. 2
  • the items 1, 2 are trimmed at their inner edges 6, 6 '. How out Fig. 2 it can be seen the items 1, 2 'at their inner edges 6, 6' rectilinear, so that rectilinear, parallel to the longitudinal axis of the items 1, 2 extending cutting edges 7, 7 'are formed.
  • the in Fig. 3 shown component 8 is formed, which has a height variable over its longitudinal axis.
  • the component 8 has over its longitudinal axis everywhere the same width, ie everywhere the same distance between the vertical sections 4, 4 '. However, it could also have a variable width along its longitudinal axis (not shown in the drawing).
  • the cross sections of the component 8 form as shown Fig. 4 can be seen, a hat profile with lower horizontal sections 3, 3 ', vertical sections 4, 4' and upper horizontal sections 5, 5 ', which along the inner cut edges 7, 7' are welded together.
  • section AA whose height is less than in the middle, namely in section BB.
  • the invention makes it possible to vary the cross section in a roll-profiled component, specifically by forming two or more individual parts or segments which have a variable cross-section in the longitudinal axis.
  • the items 1, 2 can be rollprofiled on a system.
  • the items 1, 2 are then trimmed. They can be joined together to form a discontinuously laser-bonded component.
  • the component can be manufactured by the following process steps: (1) Conventional rolling; (2) variation of both individual parts or segments, in particular in height; (3) trimming online; (4) join and weld, in particular laser welding; (5) cutting off the ends.
  • the individual parts can be produced as two rolling profiles in a scaffold.
