Definitions

  • the present invention relates to a method for producing hollow profiles with a longitudinal flange, wherein by inserting a punch in a first die a arranged between the punch and the first die board is preformed into a U-profile with a first leg and a second leg and wherein with a second die, the U-profile is formed into an O-profile with a longitudinal flange, wherein at the preforming of the board to the Ü-profile in at least the first leg a Leksflanschschenkelabêt is formed and the Leksflanschsschenabrough during the molding of the U-profile to a O-profile is formed substantially form presented to a part of the longitudinal flange.
  • a method for producing a hollow profile with a longitudinal flange for example, in DE 10 2005 011 764 A1 described.
  • a cross-sectionally U-shaped profile with parallel legs is produced in a first bending die by means of a punch.
  • this U-shaped profile is formed in a second bending die by means of an upper bending die to a tubular body with a closed cross-section.
  • a longitudinally extending flange is formed in at least one of the legs.
  • Hollow profiles with longitudinal flange are used especially in vehicle as body elements use.
  • the longitudinal flange serves for example for the connection of Body panels.
  • At the dimensional accuracy of hollow profiles ever higher demands are made. This applies in particular to the sections of the hollow profiles with which the hollow sections are connected to other components.
  • These requirements are not always met with hollow profiles manufactured with the conventional method with longitudinal flange, since due to the transport of the U-shaped profile of the first die to the second die inevitably results in a certain degree of inaccuracy, if not very complex and costly measures are taken. This applies in particular to curved hollow profiles.
  • the present invention therefore has the object of specifying a process reliable method for producing hollow sections with a longitudinal flange.
  • this object is achieved by a method for producing hollow profiles with a longitudinal flange, in which at the beginning of the preforming by means of a positioning in the direction of advance, displaceable sub-punch of the punch and a counter to the retraction direction positioned above, displaceable side wall of the first Gesenk the L jossflanschschenkelabrough is formed by further retraction of the punch in the first die of the punch and the side wall are each moved from the projecting position into a flush position and the board is preformed to the U-profile.
  • the longitudinal flange is already formed in the preforming step in which a U-profile is produced, so that the dimensions of a part of the longitudinal flange can be specified precisely.
  • the overall dimensional stability of the hollow profile can thus be improved, since in the later forming steps the high dimensional accuracy of the longitudinal flange no longer has to be taken into account explicitly.
  • Retraction in the sense of the invention means that the punch and the first die move toward one another, ie a relative movement between punch and die. This can be ensured either by a movement of the punch or the first die but also by a movement of both the punch and the first die.
  • the Leksflanschschenkelabites is inventively formed at the earliest possible time. At this time, the position of the board is specified and the risk of warping by a simultaneously running deep drawing process largely reduced.
  • the method can be further developed by using a first die with at least one first displaceable sidewall and displacing the first sidewall in the retraction direction when the U-profile is formed into the O-profile with longitudinal flange by means of the second die.
  • the sidewall can laterally support the U-profile during molding to the O-profile with longitudinal flange, so that the process reliability of the method can be improved.
  • a second die which comprises a first part die associated with the longitudinal flange leg portion and at least one further die part, and the U profile is formed into the zero profile by lowering the further die before the first die , By dividing the second die, the process reliability in forming the U-profile to the 0-profile can be further improved.
  • Double longitudinal flanges are characterized by an increased rigidity, so that higher forces can be introduced into the hollow profile with them.
  • the method can be further configured by introducing a support core, in particular an articulated support core, into the U-profile before the U-profile is shaped into the O-profile with a longitudinal flange.
  • a support core in particular an articulated support core
  • the U-profile can be supported during molding to the 0-profile from the inside and a buckling can be avoided.
  • the use of an articulated Support core allows a support even if the U-profile is to be formed into a curved hollow profile.
  • a structured support core can also be pulled out of the curved hollow profile without destruction.
  • the method can also be further developed by forming an edge joint by forming the U-profile to the 0-profile with longitudinal flange and closing the O-profile along the edge joint at least partially with material fit.
  • the heat input into the hollow profile can be minimized.
  • a change in the material properties of the hollow profile by closing can thus be largely avoided.
  • the support core is pulled before or after the cohesive closing. Pulling the support core prior to cohesive closure can facilitate the removal of the support core. For example, the risk of accidental cohesive connection of the support core is reduced with the 0-profile. In addition, the edge impact can be made accessible in this way for closing from the inside. On the other hand, a pulling of the support core allows a higher dimensional accuracy of the hollow profile to be produced.
  • the hollow profile is made of a monolithic board, a tailored blank or a patchwork blank.
  • a monolithic board is understood to be one which consists of a single sheet of a given thickness and a single material.
  • Monolithic boards can be special be inexpensively separated from cold or hot tapes.
  • "Tailored blanks” refers to blanks that are assembled from individual sheets of different thickness, strength and / or surface coating. As a result, it is possible, on the one hand, to use a thicker and / or even thinner, but also higher-strength material in places with a higher load, so that a lower weight is achieved with a higher load capacity. On the other hand, can be used at the remaining locations on thinner sheets.
  • Tailored blanks thus allow a reduction in weight with the same strength properties.
  • motherboards are strengthened locally by attaching individual additional reinforcement plates. Motherboard and reinforcing plates can be easily shaped together afterwards. The laborious and costly attachment of reinforcements on the later component can thus be omitted.
  • Tailored blanks are also suitable as base plates for patchwork blanks, wherein the reinforcing plates can be used to provide localized reinforcement in a small area, so that a further reduced thickness or another material can be selected for the individual sheets of the tailored blanks.
  • Fig. 1 shows a board 1, which is tailored specifically for the production of a hollow profile with longitudinal flange.
  • the blank of the board 1 mainly depends on the geometry of the finished hollow profile but also on the geometry of the formed during the preforming Lssensflanschschenkelabitess 10.
  • the cut board 1 between a punch 2 and a first die 3 is arranged.
  • the first die 3 is composed of two side walls 4 and 6 and a bottom element 5.

  • a first leg 8 and a second leg 9 and in the first leg a Leksflanschschenkelabrough 10 is formed.
  • a support core 11 is then introduced.
  • the U-profile is formed by means of a second die 12 to a 0-profile with longitudinal flange.
  • Fig. 4 shows a not yet completely transformed into an O-profile U-shaped profile 13.
  • the second die 12 used for molding is used shown in a slightly raised position.
  • the U-profile 13 is formed around the support core 11.
  • the shape of the L jossflanschschenkelabsacrificinges 10 is substantially retained.
  • the material is doubled.
  • this portion of the U-profile 13 is squeezed together, so that a 0-profile is formed with a doubled squeeze flange.
  • Fig. 5 shows the corresponding hollow section 14 after the laser welding of the edge joint formed by the two legs and pulling the support core 11.
  • Longitudinally of the curved hollow section 14 is a doubled longitudinal flange 15 is formed with the other components can be attached to the hollow section 14.
  • Fig. 6 shows greatly simplifies the process steps performed in the manufacture of the hollow profile, in each of which the resulting cross-sectional shapes are shown.
  • a U-profile 17 is first preformed with a first leg 18 and a second leg 19.
  • a Leksflanschschenkelabites 20 is formed in the first leg 18.
  • the U-profile 17 is formed into an O-profile 21.
  • the Leksflanschschenkelabites 20 is doubly formattahrend doubled and squeezed into a longitudinal flange 22.
  • the longitudinal flange 22 therefore has a particularly good dimensional stability and due to the doubling an enormous strength.
  • the longitudinal flange 22 can then be used very well for fastening the hollow profile or for fastening other components to the hollow profile.
  • the edge impact 23 is at least partially closed by laser welding, so that the hollow profile has a very high Stiffness receives.
  • a support core is used. This is used for complex hollow sections. For simple geometries, it is quite possible to dispense with a support core.
  • Fig. 7 shows a further tailored board 24 for producing a hollow profile. This is between a punch 25 and a first die 26, as in Fig. 8 illustrated arranged.
  • the punch 25 in this case has a partial punch 27 positioned in the retraction direction R above.
  • the partial punch 27 is associated with a displaceable side wall 28 of the first die 26, which is also positioned above.
  • the longitudinal flange leg portion 29 in the first leg 30 of the in the first leg 30 of the in the Fig. 9 illustrated U-profile 31 formed.
  • the partial punch 27 and the side wall 28 are displaced into a flush position and the first leg 30 and the second leg 32 are formed.
  • an articulated support core 33 is introduced into the further arranged in the first die 26 U-profile 31.
  • the second die 34 is composed of a first part die 35 assigned to the longitudinal flange leg portion 29 and a further part die 36, Fig. 10 ,
  • First, according to Fig. 11 moves the partial die 36 in the direction of the first die 26.
  • the part of the U-profile facing away from the longitudinal flange leg section 29 is deformed.
  • the part of the die 35 lowers, so that an O-profile is formed.
  • the hollow profile 37 can be very complex shaped, for example, be curved. Nevertheless, the method according to the invention makes it possible to produce a hollow profile with a longitudinal flange 38 which is highly dimensionally stable.
  • Fig. 13 are the individual process steps of the last embodiment of an inventive production of a hollow profile illustrated by the individual cross-sectional shapes during the process steps illustrated (without support core).
