Definitions

  • the invention relates to a device according to preamble of claim 1 for forming a board to a hollow profile with at least one base plate on which the reshaped board can be placed at least one punch core for the hollow profile and at least two die halves for forming the board to the hollow profile and a method
  • a device and method are known from US 2158176 known.
  • stiffening and / or functional elements are generally understood tabs, brackets, flanges, etc., which are used on the one hand, for example, for attaching other hollow sections, so-called flange or connection elements.
  • flaps bent over by 180 ° can also form stiffening elements by forming a region with a double board thickness.
  • connection elements for connecting a further component is introduced into a hollow profile to be wound up.
  • the introduction of the connection elements should, however, take place in a prebent region of the hollow profile in order to ensure the dimensional accuracy of the introduced connection opening.
  • the connection elements are formed from a prebent region of the board, but these still have residual bends. Due to the residual bends, the distance between the areas of the connection elements to be joined together varies.
  • the known connection elements ensure no ideal joining conditions, so that the process reliability decreases when joining various hollow profiles.
  • the present invention has the object to provide a method and an apparatus for producing a hollow profile with at least one molded stiffening and / or functional element of a board available, with which or with which corresponding hollow profiles can be produced inexpensively, at the same time ensure high process reliability when connecting different hollow profiles.
  • the above-described object is achieved by a generic device in that at least one forming die is provided, with which an introduced into the planar board element structure in a stiffening and / or functional element can be formed and / or fixed.
  • the steps of molding or fixing the stiffening and / or functional elements can be integrated with the steps for forming the board to the hollow profile in a device, so that the number of steps is reduced by avoiding additional set-up or positioning steps.
  • a minimization of the setting or positioning steps is achieved by providing means for punching and / or cutting the element structure in the planar board.
  • By appropriate means and the upstream process of punching or cutting the element structure can be integrated into the planar board in the device, so that all steps starting can be performed from a flat board to the finished hollow profile with molded stiffening and / or functional elements in a device.
  • the means for punching and / or cutting the element structure in the planar board are at least partially integrated in the punch core, so that the structure of the device according to the invention is simplified.
  • the position of the individual stiffening and / or functional elements in the finished hollow profile can be varied particularly easily by incorporating means movable in the stamp core for cutting and / or punching.
  • the stated object is procedurally achieved in that using the device according to the invention by punching and / or cutting a later stiffening and / or functional element forming element structure is introduced into the planar board, at least one forming die the element structure forms the stiffening and / or functional element and optionally fixed and then the board is formed into a hollow profile.
  • the stiffening and / or functional elements are formed according to the invention from the planar board, so that this principle has no residual bending conditionally and ideal joining conditions when connecting made of several hollow profiles are ensured by the inventive method.
  • the tooling costs for the production of the hollow profiles can be low be kept because the formations always takes place in the planar board and the tools can therefore be designed according to simple.
  • the stiffening and / or functional elements need not be added to the hollow profiles, so that the number of work steps and the production costs for producing a hollow profile with stiffening and / or functional elements can be reduced.
  • a further reduction of the manufacturing costs is, according to a next embodiment of the method, achieved in that after placing the board on a base plate of an apparatus for forming the board to a hollow profile of the forming die forms the element structure and optionally fixed.
  • the number of necessary punching and / or cutting tools is minimized by the punching and / or cutting of the element structure by means provided in the apparatus for forming the board to a hollow profile provided movable means for punching and / or cutting the board.
  • An economical production of longitudinally welded or joined tubes in medium quantities thereby gephilrleitstet that when forming the board to the hollow profile, the board is pressed by a punch core against a hollow profile shaped support plate, laterally disposed die halves that Form hollow profile against the punch core and optionally joined the opposite longitudinal edges of the formed board, in particular welded.
  • Said method can on the one hand produce hollow profiles with different lengths with little effort and, on the other hand, can be adapted with little effort to the production of different cross-sectional shapes of the hollow profiles by exchanging the die halves and the die.
  • hollow profiles can be provided both with integrally formed and also attached stiffening and / or functional elements.
  • illustrated boards 1, 2 have according to a first embodiment of the method introduced element structures 3, 4.
  • the element structures 3, 4 generally consist of stamped or cut openings in the sinkers 1, 2, which can be converted into stiffening and / or functional elements, for example connection or flange elements.
  • Fig. 2 a) and b) are the boards 1, 2 shown to a hollow profile 5, 6 formed.
  • the element structures 3, 4 have been formed using a forming die, so that the hollow profile 5, 6 is a functional element, in this case a connecting element 7, 8 having.
  • the stiffening and / or functional elements can be formed at any point of the hollow profile, for example on the front side or in the middle of the hollow profile.
  • the shows Fig. 2 a) and b) only the formation of the functional elements 7, 8 as connecting elements.
  • a stiffening element can be easily achieved by bending the individual cut out tabs of the element structure by 180 °, so that an area with double board thickness is formed.
  • connecting elements 7, 8 were formed from the planar board 1, 2, the tabs are flat and show no disturbing residual bends.
  • the connecting elements 7, 8 produced by the method according to the invention therefore ensure ideal joining conditions for adding further hollow profiles.
  • Fig. 3 is now shown in a sectional view schematically the region of the die of an embodiment of a device according to the invention for forming a circuit board to a hollow profile.
  • the Fig. 3 shows a base plate 9, which has a recess 10, wherein the recess for forming the previously brought into the board and in Fig. 3 not shown element structures is used.
  • two die halves 11, 12 shown which by forming a closing movement of the board 13 against the punch core 14 to form a hollow profile, for example, with a nearly square cross-section.
  • the forming die 15 which is integrated in the punch core 14, on the one hand serves, before the closing movement of the die halves 11, 12, the element structures to form a stiffening and / or Functional element, for example, form terminal element, wherein the circuit board 13 rests on the base plate 9.
  • the stiffening element and / or functional element 16 during forming into a hollow profile.
  • the punch core in the Fig. 3 not shown means for punching and / or cutting the element structures in the board, so that a hollow profile with integrally formed stiffening and / or functional elements can be prepared in a single operation, starting from a flat board.
