Definitions
- the invention relates to a device for producing at least partially closed hollow sections of a
- the invention relates to a method for producing an at least partially closed hollow profile of a circuit board.
- At least partially closed hollow sections are often used in the automotive industry to replace open and welded profiles.
- Standard U-O forming requires at least two forming steps, with each forming step being carried out separately in one or more presses and passing the component between the workstations. With a favorable design, although a finished part can be produced per press stroke, but this requires
- German Laid-Open Publication DE 10 2007 021 798 A1 is a device for producing at least
- the cycle time achievable by this device is in need of improvement, since a finished part is produced only with every second press stroke.
- the present invention is based on the object, an apparatus and a method for producing at least partially closed
- the object is achieved by a device in that the tool set in the axial direction of the produced at least partially closed hollow profile runs parallel to each other and in the closing direction of the tool halves
- the die receiving more than two at least partially U-shaped dies, wherein the number of dies is a multiple of two.
- the matrix recording can therefore preferably four, six or contain, for example, eight U-dies, so that the Matrizenaufnähme can simultaneously accommodate several reshaping boards. In particular, the removal of the finished
- the die holder according to a further embodiment of the device in
- the device can therefore be configured advantageously in that bearing blocks for rotatably supporting the die receiving and at least one Kernzugvorides are provided, wherein the at least one Kernzugvortechnisch is optionally arranged on the bearing blocks.
- the U-punch is disposed below the upper die, wherein the U-punch optional hold-down
- the arrangement of the U-punch below the upper die allows easy insertion of a board for performing the U-forming.
- the optionally provided hold-downs in the first half of the mold allow a controlled insertion of the board during the U-forming and ensure, in particular, if this until the
- Vertex baseline of the U-stamp the first tool half can be moved, a further improved insertion of the board.
- the maximum unrolled side wall length of the hollow profile to be produced corresponds to the maximum length of a U-leg of the at least partially U-shaped formed board.
- the corresponding expression of the side walls of the at least partially U-shaped dies of the die holder allows a U-forming, which offers a higher process reliability in the subsequent 0- reshaping especially for strongly rebounding materials, since the legs of the at least partially U-shaped board in this Do not fall by
- legss of at least partially U-shaped formed board must be performed in the upper die of the second tool half, simplified and made more reliable process. In addition, funds can carry on further
- the above-described object is achieved by a method for producing an at least partially closed hollow profile from a circuit board using the device according to the invention with the following steps:
- a support core can be positioned via a core pulling device in the at least partially U-shaped formed board, which is removed again before the removal of the finished hollow profile.
- both a U-forming and a 0-forming in the device is performed simultaneously by only one closing operation of the mold half.
- Cycle times of the method according to the invention are correspondingly low.
- the method according to the invention can be further improved by virtue of the die receptacle having at least partially egg-shaped dies and the die receptacle being rotated by 90 ° after each opening of the first and second mold halves. This ensures that the cycle times for rotation of the die receiving and positioning of an at least partially U-shaped formed board are reduced in the second mold half. In addition, a simple removal of the finished formed parts after the O-forming and the rotation of the Matrizenapplication is made possible by 90 °.
- Displacement of the displaceable portions of the side walls are omitted, so that the device is further simplified.
- the movable sections can, for example spring-loaded, so that after opening the second tool half in its original position
- the method is further improved in that further work steps are performed on the at least partially U-shaped board or on the at least partially closed hollow profile in the die receiving.

- Fig. 1 shows first an embodiment of the apparatus for producing at least partially closed hollow sections of a circuit board in the open state.
- the device 1 has a tool set 2, 5, which comprises a U-punch 3, which is arranged in the first mold half 4. Further, an upper die 6 is included, which is arranged for forming an at least partially U-shaped board in an at least partially closed profile in the second mold half 7. Furthermore, it can be seen that the
- the die holder 9 comprises in the embodiment shown here four identical, at least partially U-shaped dies 10, which are arranged in a star shape around the axial axis 11 of the die holder 9.
- the die holder 9 is rotatably mounted about its axial axis 11. About a here only schematically illustrated positioning drive 12, the die holder can be rotated.
- FIG. 1 also shows a Kernzugvorraum 13, which is arranged in the region of the second mold half and allows the introduction of a support core in the reshaping at least partially U-shaped board or its removal after the forming process.
- Kernzugvortechnische 13 used supporting core is not shown here.
- the Kernzugvortechnisch 13 is on bearing blocks 14, which are also shown here only schematically arranged.
- weight loss means are 15,
- FIG. 2 shows the embodiment of Fig. 1 also in a perspective schematic representation with an inserted board 16 and an at least partially U-shaped reshaped board 17.
- the board 16 lies on the reaching to the apex baseline of the punch 3
- the side walls of the U-shaped dies 10 have a height which is at least half of the maximum rolled side wall length of the hollow profile to be produced, ie the length of the legs of the U-shaped formed board. In addition, sliding in the side walls
- Subregions 19 are provided, which improved the
- FIG. 3 now shows the device 1 in the closed state, ie with a closed tool set 2, 5. It can be seen that the circuit board 16 has now been formed into an at least partially U-shaped circuit board. In FIG. 3, in addition to the U-shapes which are not involved in the forming process,
- Dies 10 of the die holder 9 an at least partially U-shaped formed plate 20 and a finished molded at least partially closed hollow profile 21 shown, which from the U-forming or from the O-forming in the first mold half 4 respectively in the second

- Matrizenage 9 is freely rotatable.
- the directions of movement 22 of the tool half 7 and the die holder 9 are shown in Fig. 3.
- the finished molded, at least partially closed hollow profile 21 can be removed in a simple manner after the O-forming and a rotation of the die holder 9 by 90 ° counterclockwise from the U-die 10, for example using a corresponding robot. Due to the simple construction of the device according to the invention, it is thus possible to carry out a forming movement simultaneously two forming processes, a U-forming and an O-forming, and also to ensure easy removal of the finished products from the device.
- the second tool half 7 comprises an upper die 6, the side walls 6a and 6b of which on the
