Definitions

  • the invention relates to a method for forming hollow sections having at least one opening, wherein in the hollow profile, a fixed insert is placed and the hollow profile is applied externally by the action of a forming device with at least one forming force to achieve a hollow profile end shape and reshaped.
  • Hollow sections per se, ie structural elements with a closed, non-massive cross section, has long been known and generally well controlled, for example by extrusion. Hollow sections have - depending on the precise design - a very good ratio between the achieved stiffness of the hollow body, in particular bending and torsional stiffness, and the amount of material used.
  • hollow sections with a constant over the longitudinal extent of the profile cross-section are relatively easy to produce, however, often, for example, in the body structure, form requirements made that make a far-reaching transformation of the hollow section required.
  • Hollow profiles with constant cross-section, with single or multi-chamber cross-sections require over the deformation of solid bodies of a special, more complex treatment, since in the external action of a forming force on the hollow profile there is a risk of buckling and cracking.
  • the hollow profiles often do not accept the desired contour of the tools of the forming in the molding process, on the contrary, even significant deviations from the target contour remain, which is due to constriction and different compression and elongation of the hollow profile material.
  • Object of the present invention is to avoid the drawbacks in known methods for forming hollow sections - at least partially - to provide, in particular a method that allows deformation of hollow sections with high dimensional accuracy, in particular without deposits within the reshaped hollow profile remain.
  • the indicated object is achieved according to the invention first and essentially in the subject method in that the insert is transferred after and / or upon achievement of the hollow profile end shape at least partially in a liquid and / or gaseous state and substantially completely from the hollow profile Will get removed.
  • the insert liquefies after or during the transformation - which also includes a resolution - or is gasified, it is usually readily removable from the formed hollow section and can - depending on the material used - be reused or recycled. If it is mentioned that the insert located in the liquid and / or gaseous state "substantially completely" is removed from the hollow profile, then it is meant that at least a significant proportion of the deposit material is removed from the hollow profile, preferably more than 80%, more preferably more than 90%, most preferably more than 99% of the insert material originally used. Hollow sections frequently have openings at their ends even after a forming process, from which openings the fluid and / or gaseous state can flow out or flow out. If, after the forming of the hollow profile, such an opening is no longer present, in a preferred embodiment of the invention, an opening is introduced into the hollow profile to remove the transferred into a liquid and / or gaseous state deposit.
  • the insert is converted into a liquid and / or gaseous state by the insert is heated directly or indirectly via the hollow profile.
  • An immediate heating of the insert can for example be ensured by the fact that the insert also a heater - for example in the form of a heating wire - introduced into the hollow section and placed there, the heater is activated to liquefy the insert in retrospect.
  • the heating device can either be pulled out of the hollow profile or remain in the hollow profile if the hollow profile has been over-embossed for a distance.
  • the indirect heating of the insert over the hollow profile is possible, for example, by the use of thermal radiation or in that the hollow profile is exposed to a heat bath.
  • Materials with a lower melting temperature are advantageous in that less energy has to be expended in order to remove them from the hollow profile after the forming process, therefore it is also preferable to use material which a melting temperature more than 60 ° C, more preferably greater than or equal to 40 ° C. If the manufacturing environment allows it, a melting temperature of only greater than 30 ° C. may also be advantageous. Although, in principle, materials can be used whose melting temperatures are below the working temperature, but these are inevitably expensive to handle, since they are in other temperature ranges -. B. climate chamber - must be provided and processed quickly to prevent premature liquefaction.
  • wax or a wax-like substance is used as the material for the insert, "wax-like substance” referring in particular to the mechanical properties of wax (viscosity, hardness, toughness), not to the optical properties.
  • Waxes have the property that they are plastically deformable under normal conditions - ie under normal atmospheric pressure at about 20 ° C - without cracking or crumbling, but are still relatively dimensionally stable
  • most waxes are free of pollutants and therefore manageable even in direct contact with wax, which also has a very significant technical advantage, since it can be used to seal off Surfaces and thus used for corrosion protection Especially in the automotive industry, cavities, in particular cavities in hollow profiles, are sealed by wax for decades.
  • the opening of the hollow profile - or the openings - is sealed after introduction of the insert, in particular by embossing and / or by applying or introducing a stamp, for example a stamp of the forming device.
  • a stamp for example a stamp of the forming device.
  • the volume of the insert is such that it corresponds to the volume of the hollow profile upon reaching the hollow profile end shape.
  • the insert acts in the hollow profile not only as a counter-support based on a pure reaction force, but there are during forming areas of the hollow profile in which due to the hollow profile internal pressure exerted a resultant, outwardly directed force on the wall of the hollow profile becomes. Overall, this leads to a much better dimensional accuracy of the resulting formed hollow profile than is the case with hollow sections, which have been produced without such an insert - in particular wax-like insert.
  • Another advantage of the method according to the invention is therefore that even - assuming the choice of a suitable material for the deposit, such.
  • B. wax - a reshaping of the hollow profile from the inside to the outside with conventional forming devices is possible without having to resort to expensive devices, as used for example in the hydroforming.
  • a further advantageous embodiment of the method is that the insert is placed in the hollow profile by the material in the liquid state of the insert is filled in the hollow profile and the material of the insert is cooled to solidification in the insert.
  • FIG. 1 and 2 a method for forming hollow sections 1 is shown with at least one opening 2, the Fig. 3 and 4 show process products, hollow sections 1 "in hollow profile final form.
  • FIG. 1 shows in an overview, the time course of the actual process can not readily recognize the necessary for carrying out the process elements, namely a fixed insert 3, - present three fixed deposits 3, one insert for each of the three chambers - and a forming device 4a, 4b, wherein the hollow profile Outside by the action of the forming device 4a, 4b applied with a forming force to achieve a Hohlprofilendform and reshaped.
  • FIG. 1 the different deformation states of the hollow profile 1 are shown, wherein the unprocessed hollow profile 1 to the hollow profile 1 'closed by sealing points 5, from which finally the hollow profile 1 "in hollow profile final form 4b of the shaping device 4a, 4b are moved toward one another under the action of force and reshape the inserted hollow profile 1.
  • the upper tool 4a and the lower tool 4b accordingly have the negative form of the desired hollow profile shape, which should come as close as possible to the hollow profile end shape characterized in that the insert 3 is transferred after and / or upon reaching the Hohlprofilendform the hollow section 1 in a liquid and / or gaseous state and substantially completely removed from the hollow profile 1, which is not explicitly illustrated, but readily understandable ,
  • the insert 3 is converted into a liquid state by the insert 3 is indirectly heated via the hollow profile 1, namely, as in Fig. 2g indicated, is exposed to a stream of hot air.
  • the indirect heating of the insert 3 via the hollow profile 1 is particularly suitable when the hollow profile 1 consists of a good thermal conductivity material.
  • the hollow profile 1 consists of an aluminum alloy, which is highly thermally conductive. This is advantageous in this case, because automatically first the areas of the insert 3 are heated and liquefied, which are responsible for the fact that the insert 3 in the reshaped hollow section 1 "adheres.
  • the deformed metallic hollow profile 1 is inductively heated
  • the deformed hollow profile 1 is used for the heat treatment hung so that the insert automatically releases by gravity from the hollow profile, as soon as the edge areas have been liquefied enough.
  • 3 wax is used as the material for the insert, which has a melting point at about 40 ° C.
  • the working temperature at which the process described here is carried out is usually between 18 ° C and 25 ° C, a temperature range at which ordinary wax is readily plastically deformable without cracking or breaking.
  • Fig. 2 a nearly complete process flow is shown.
  • the insert 3 is placed in the hollow profile 1; the insert is already fixed during the placement.
  • the insert or the liquefied material of the insert is introduced into the reshaped hollow profile and cooled only in the hollow section so far that the material of the insert 3 solidifies into a solid insert 3.
  • Fig. 2b It is shown that the openings 2 of the hollow profile 1 are sealed after introduction of the insert 3, namely by embossing with stamping dies 6.
  • the sealing point 5 is located adjacent to the insert 3 in the hollow section 1 or the insert 3 is already through the Embossing compacted at the sealing points 5 in the hollow section 1.
  • the cavity of the hollow profile 1 is almost completely filled with the insert 3.
  • the volume of the insert 3 corresponds to the volume of the hollow profile 1 "upon reaching the hollow profile end shape., That means that at the completion of the forming process, the largest internal pressure is generated Volume of the hollow section 1 corresponds, the greatest possible conversion from the inside to the outside can be achieved, since practically at the beginning of the forming process, a considerable hollow profile internal pressure is generated Fig. 2g It can be seen that the end portions 7 of the deformed hollow profile 1 "are separated so that the subsequently liquefied insert 3 can flow out of the formed hollow profile 1". In other, not shown embodiments, smaller openings in the formed hollow section 1 "are introduced to remove the converted into a liquid state insert 3 can.
  • Fig. 3 and 4 are compared with the forming results which can be achieved with a conventional non-insert method ( Fig. 3 ) and which can be achieved with the method according to the invention - here with a wax-like insert 3.
  • Fig. 3 is good to realize that without the use of an insert no hollow profile internal pressure can be generated, which leads to an unsatisfactory shape, since only embossing contours can me poorly profiled transitions can be achieved; Bulges can not be generated at all, although the forming device provides the necessary space for it.
