Definitions

  • the invention relates to a composite profile with a support body made of a light metal material as a profile component and at least one with it during an extrusion process metallically bonded as a surface coating further profile component, in particular a profile band from a different metal.
  • the invention also covers a method for producing a composite profile two profile components.
  • DE-PS 24 32 541 of the applicant is a method for Manufacture of busbars from a support profile and at least a part of the surface of the Carrier profile-forming support from another's ribbon Remove metal.
  • the carrier profile by pressing out a block generates the shaping cross section of a die, and at the same time, the profile strip runs through to the longitudinal axis of the die parallel to the die opening or shaping cross section.
  • the inventor was aware of this state of the art set the goal, the connection between beam profile and profile tape while maintaining the special economic Manufacturing opportunities further improve.
  • the profile strip has at least one its longitudinal edges from its inner surface on the supporting body protruding formations at a distance, which are embedded in the support body.
  • the should Formations limit undercut gaps, which from the metallic material of the support body are filled out.
  • the additional elements should be preferred to the profile tape be welded and, if necessary, an undercut Limit space that - as mentioned above - from metallic material of the support body with a positive fit is filled out.
  • the formations to the inner surface of the profiled belt must be inclined, if so arise two different directions of inclination.
  • the profile band parallel to its longitudinal edges as an additional element fixed at least one wire organ, preferably one Round wire welded in the central axis of the profile. Or it will at least one channel profile attached to the profile tape, that its gutter leg from the inner surface of the profile strip or the underside of the steel strip directed away are.
  • these gutter legs can also be in one Angles run to the inner surface, especially to the outside - so away from the longitudinal edges of the profile - be inclined.
  • Another embodiment includes on the steel band welded bolts as anchor elements.
  • An inventive method for producing the Composite profile is characterized in that in the Light metal matrix from the level of the band-like profile component outstanding forms embedded and with her be positively connected.
  • Composite profiles 10 as parts of a so-called multiple composite profile 11 generated jointly in one embodiment each with a rail-like support body 12
  • Rail heads 16 formed on both sides of a web 14 on the one hand and at least one with one of the rail heads 16 connected profile strip during the pressing process 18 on the other hand.
  • the latter is made from an iron or Non-ferrous metal, the support body 12 made of an aluminum alloy.
  • the profile strip 18 becomes a forming one Die breakout or shaping cross section of the Extruded press fed and migrated along with it the one from a hot bolt in flowable condition transferred matrix from an aluminum alloy, whereby thanks to the two metal materials on their contact surfaces of the high molding pressure.
  • the boundary surfaces of the shaping cross section due to contact with the edges and surfaces of the ready-to-use profile strip 18 are the profile strips 18 adjacent composite profiles 10 on top of each other.
  • the harder composite partner that is the profile band 18, is preparatory to its particularly recognizable in FIG. 4 Longitudinal edges 20 with the inner surface of the supporting body 21 of the profile strip 18 protruding formations or formations 24 provided, which at a medium distance f are provided from each other and thus undercut between them Limit recesses 26.
  • the enlarged representation of two hollow profiles 10 h of FIG. 2 with profile tape support shown in FIG. 3 shows on the one hand a position of the formations 24 that is inclined outward here at an angle w and on the other hand indicates that the formations 24 of the two adjacent profile strips 18 can be offset from each other in side view.
  • center, the protrusions 24 a projecting at right angles from that inner surface 21 of the profile strip 18 are at an angle e to the longitudinal axis M of the composite profile 10.
  • the inclined or right angled position of the formations 24,24 a is either produced prior to the feed of the profile bands 18 to the extruder or immediately before entering the mold cross-section of the shaping cross-section extrusion die offering by a bending device.
  • the three configurations of the profiled strips 18, 18 a , 18 b shown in FIG. 4 either have shapes 24 of trapezoidal shape on the longitudinal edges 20 or hook-like shapes 24 a , 24 b with hook ends 25 running at a distance a from the profile surface 21.
  • a row of projections 24 m running at the center axis M of the composite profile 10 and molded onto that inner surface 21 is indicated at a distance n from the longitudinal edge (s) 20.
  • T-shaped formations 24 c and formations 24 d for the manufacture of which bores 30 are made in an angle leg 28 of a profile strip 18 d , after which an edge strip 29 of height b of the angle leg 28 is removed.
  • the profile strip 18 is made of a steel strip Width c - or a distance between the two longitudinal edges 20 from each other - from here 75 mm and a height h of 4.5 mm preparatory to its inner surface 21 in Profile center axis M, for example, by resistance roller seam welding with a round wire 23 of diameter d from about 6 mm has been connected, which then made into the matrix an aluminum alloy - support body 12 - embedded becomes.
  • the profile strip 18 of FIGS. 8, 9 carries a channel profile 36 or 36 a welded onto the inner surface 21 from a steel strip, preferably made of stainless steel, with a thickness q of here 2 mm. Legs 37 of a length t of 6 mm are formed at right angles from this steel strip in FIG. 8, which are inclined outward at an angle w 1 in the embodiment 37 a according to FIG. 4.
  • Both designs can be used as channel profiles 36, 36 a with a constant leg length t, or - as shown in FIG. 10 - recesses 40 of length g are made in the legs 37, 37 a ; the length of the crenellar leg portions 42 remaining therebetween is denoted by g 1 .
  • This cross-stamped channel profile 36, 36 a is also resistance welded on the steel.
  • Fig. 11 shows from the inner surface 21 of a profile strip 18 projecting bolts 32, 32 a , 32 b , which are connected to the profile strip 18 by shooting bolt welding.
  • the left bolt 32 is frustoconical and creates an undercut ring surface 34.
  • the middle bolt 32 a is equipped with an external thread 35, whereas the right bolt 32 b is formed by a square profile.
  • These additional elements or bolts 32, 32 a , 32 b indicated by way of example can be distributed as desired on the inner surface 21.
  • All of the additional elements 23; 32, 32 a , 32 b ; 36, 36 a are anchored in the finished composite profile 10 in the light metal matrix; thanks to these additional elements 23; 32, 32 a , 32 b ; 36, 36 a - and other configurations of the formations are conceivable - a positive mechanical connection is created during the pressing process in addition to the metallic bond between the two profile components or bond partners 12 and 18.
  • the profile strips 18 are, for example, by two reels angled and walk through before entering the Extrusion die or the tool a heating device as well a brush station in which the profile strips 18th adherent oxide layer to ensure the metallic Bond is removed. After the actual pressing process the profile strips 18 come out of the tool with them compressed light metal attached as support body 12, in which - as I said - they are so embedded that they the tool in the area of the cross section of the mold, or only touch little.
