Definitions

  • the present invention relates to an apparatus for manufacturing a closed profile having a cross-section varying in longitudinal direction to the use of an apparatus for manufacturing a profile as well as to a method for manufacturing a profile.
  • Profiles made of sheet metal are widely used in the prior art, e.g. in manufacturing bumper beams for the automobile industry.
  • the bending facilities comprise bending means for bending the sheet metal in a bending direction other than the moving direction of the sheet metal.
  • the bending means frequently consist of at least two opposing moulded forming rollers contacting an upper and lower side of the sheet metal directed in-between to perform a bending operation based on a respective mould of the forming rollers.
  • the rotary axis of the moulded forming rollers has a constant orientation. To allow bending of sheet metals having different diameters, the distance between the rotary axes of the opposing moulded forming rollers frequently can be adjusted.
  • DE 100 11 755 A1 proposes the use of transforming rollers which are variable adjustable in a bending direction during bending operation.
  • the transforming rollers contact an upper and lower side of the sheet metal directed in-between to perform a bending operation.
  • DE 100 11 755 A1 additionally discloses the use of transforming roller-orientating means, which guarantee a tangential contact between the transforming rollers and the sheet metal during bending operation.
  • Deep-drawing/stamping usually is performed by pressing sheet metal into a mould by using a stamp corresponding to the respective mould. In consequence, deep-drawing/stamping usually is not performed continuously but in line with the work cycle of the stamp.
  • Both, the above described bending and deep-drawing/stamping operation requires a certain formability of the material used for the sheet metal to achieve a desired geometry. In consequence, it is frequently necessary to simplify the geometry to allow use of a certain material. Especially the use of materials showing a poor formability at room temperature (e.g. magnesium, aluminium and high strength steels) is extremely difficult since these materials tend to rip during deep-drawing/stamping operations.
  • materials showing a poor formability at room temperature e.g. magnesium, aluminium and high strength steels
  • the radii at bending edges usually have to be significantly more than e.g. 3 times the thickness of the used sheet metal to allow deep-drawing/stamping of the sheet metal.
  • the temperature of the sheet metal might be increased during deep-drawing/stamping operation to increase formability of the respective material.
  • a temperature around 900°C is required to significantly increase formability.
  • Aluminium and magnesium require a temperature of between 200°C to 250°C to significantly increase formability.
  • heating means for the sheet metal has to be provided. Said heating means significantly increases the manufacturing costs. Furthermore, immediate further processing of the manufactured parts frequently is not possible, since the manufactured parts have to be cooled down first.

  • the inventive apparatus allows manufacturing of a closed profile made of a sheet metal having an elongation after fracture A 80 of less than 15 %.
  • the inventive apparatus is especially suitable for processing sheet metal consisting of a material having a poor formability at room temperature.
  • This increased field of application is caused by the surprising effect realised by the inventors that a tangential contact between the transforming rollers and the sheet metal directed in-between during bending operation significantly decreases the occurrence of cracks during bending operation.
  • the achieved bending radii are three times or less since three times the thickness of the sheet metal used. More preferably, the bending radii in a direction orthogonal to the longitudinal direction of the profile are less than 1.5 times and most preferably less than 1 times the thickness of the sheet metal.
  • the sheet metal is made of aluminium or magnesium or martensitic steel or a light metal alloy since these materials combine light weight with a high stability.
  • the resulting profile is at least partially closed.
  • a sheet metal of rectangular shape can be used and no synchronisation between the position of the sheet metal and the bending operation of the opposing transforming rollers is necessary.
  • the resulting profile is completely closed and the used sheet metal is of non-rectangular shape.
  • a synchronisation between the bending operation performed by the opposing transforming rollers and the position of the sheet metal is necessary.
  • the used sheet metal has a varying thickness to provide a variable strength of the profile.
  • the thickness of the sheet metal varies about 1% in longitudinal direction and more preferably about 0,5% in longitudinal direction to avoid sudden changes of thickness and thus cracks in the transition area where the thickness changes.
