Definitions

  • the invention relates to a method for producing an at least partially closed sheet metal profile made of metal and to corresponding uses.
  • Formed sheet metal components which have at least two longitudinal edges with an edge contour along which a closed sheet metal profile (profile with a closed cross section) is produced by means of a form fit and material connection are known from the prior art, see for example DE 103 21 863 A1, WO 1993 / 005903 A1, US Pat. No. 3,273,601 A and US Pat. No. 2,317,198 A.
  • the methods known from the prior art for producing sheet metal profiles with closed cross-sections are only limited to relatively simple cross-sections and do not allow the production of individual and / or complex profile geometries .
  • the invention is therefore based on the object of providing a method for producing an at least partially closed sheet metal profile with which individual and / or complex profile geometries can be produced.
  • this object is achieved by a method having the features of claim 1.
  • a method for producing an at least partially closed sheet metal profile from metal comprising the following steps:
  • the first longitudinal edge at least partially having a first edge contour and the second longitudinal edge at least partially having a second edge contour
  • the first The edge contour is designed to be complementary to the second edge contour, in such a way that the longitudinal edges interlock via the edge contours and are thus initially connected with one another in a form-fitting manner and then the longitudinal edges that are interconnected with one another in a form-fitting manner are at least partly materially connected to produce an at least partially closed sheet metal profile.
  • the longitudinal edges are at an angle to one another and are connected to one another.
  • the planes of the longitudinal edges are therefore essentially not congruent, so that they have an angle of less than 180 °, in particular less than 160 °, preferably less than 140 °, preferably less than 120 °.
  • the angle is designed as an obtuse angle, particularly preferably as an acute angle. Due to the "angled" arrangement of the longitudinal edges to one another, individual and / or complex profile geometries can be produced.
  • this object is achieved according to a second embodiment by a method having the features of claim 2.
  • a method for producing an at least partially closed sheet metal profile from metal comprising the following steps:
  • the first sheet metal blank is formed into a first sheet metal component, the first longitudinal edge of the first sheet metal component at least partially having a first edge contour and the second longitudinal edge of the first sheet metal component at least partially having a second edge contour.
  • the at least second sheet metal blank can be formed into a second sheet metal component, the first longitudinal edge of the second sheet metal blank or of the second sheet metal component at least partially having a first edge contour and the second longitudinal edge of the second sheet metal blank or of the second sheet metal component at least partially has a second edge contour in regions.

  • the edge contours of the longitudinal edges are generated by means of a laser.
  • a laser to cut an edge contour along a longitudinal edge allows a more filigree cut compared to mechanical cutting, for example punching, and preferably enables the formation of complementary edge contours essentially without further post-processing of the edge contours on the longitudinal edges that are initially to be positively connected.

  • the material connection is generated by means of a laser.
  • a laser for material-to-material connection (welding) can be aimed specifically at the longitudinal edges that are already positively connected to one another due to their edge contours.
