Definitions

  • the invention has for its object a method for Manufacture of body and chassis parts for vehicles specify with which also longitudinally welded aluminum pipes and roll-formed profiles as well as open rolled profiles with different Wall thickness can be produced.
  • the actual Profile forming process in which the flat ribbon-shaped plane Semi-finished products by means of which form a tubular profile or an open profile Rolling is formed at least one further processing upstream.
  • the required ones Wall thicknesses of the final body and chassis parts determined become.
  • the material thickness is selectively across the width of the semi-finished product formed to the required wall thickness. This happens through upstream rollers.
  • This keeps the plane Material is the material thickness, which is the tube or profile wall thickness after forming into the desired tube profile or open Profile then in the appropriate places without further Post-processing forms.
  • the method according to the invention has the advantage that it integrates into existing production lines can be.
  • the flat strip-shaped semi-finished product selectively over its length using upstream rollers to the material thickness required for the required wall thickness be reshaped. It is so different Wall thicknesses not only over the circumference of the profile but also to achieve over the length of the profile, i.e. in the axial direction.
  • the wall thicknesses can also be varied in this way local loads over the length of the pipe or open Customize profiles. Furthermore, another material and Weight saving possible.
  • the material thickness of the flat flat flat semifinished product can be chosen so that in connection with the material forming Increase in thickness in areas laterally in addition to the areas processed by rollers, just the areas needed Wall thickness of the final body or chassis part having. This way it becomes a particularly good one Utilization of the raw material achieved and it can be inexpensive Insert semi-finished products.
  • the arrangement of the tubular profile or open is expedient Profile-forming rollers depending on the changed section modulus the change in thickness previously occurred and hardening of the flat band-shaped material. This arrangement takes into account the previous processing changed moments of resistance and thus achieved that the extent of finishing after performing the Forming and possibly the longitudinal seam welding less can fail.
  • Fig. 1 shows a schematic representation of a production line.
  • a magazine 10 continuously becomes a flat ribbon flat semi-finished product of specified width and thickness fed.
  • the semi-finished product came to a first processing station 12, where it is selectively over its Width and possibly also over its length to the material thickness required for the required wall thickness is reshaped.
  • a Pipe profile or open profile forming rollers that first still flat band gradually formed into the final profile. The areas in which the material thickness previously reached has been changed to the intended positions in a certain one, from the original material thickness deviating wall thickness is required.
  • the lateral ones Edges of the originally flat semi-finished product are adjacent to one another and are optionally in a third processing station 16 longitudinally welded.
  • a fine calibration by by further Roll the final desired external dimension by forming is achieved.
  • a fifth processing station 20 the continuous pipe or profile strand separated into pipe or profile sections.
  • Figures 2a to c show examples of tube profiles that were produced by the method according to the invention.
  • Figure 2a is a rectangular profile in which the wall thickness s1 is equal to 1/2 s2.
  • Figure 2b is one oval profile in which the wall thickness s1 is essential is larger than s2.
  • Fig. 2c there is a triangular one Profile shown.
  • the wall thicknesses s1 and s2 are one below the other equal and larger than s3.
