    The present invention relates to a bending machine according to the preamble of claim 1.
    Bending machines are known which, for example, bring steel wire into a "zig-zag" shape with the aid of a bending ram, wherein the ram can be moved by two linear drives. At a free end of the bending ram there are bending surfaces which exert pressure against the wire. The wire itself is held by two clamping mechanisms. ES is also provided with an advancing device so that the working rhythm consists of the steps advancing the wire, fixing the wire by two clamping mechanisms , Bending of the wire by the bending ram, releasing the clamping mechanisms, feeding the wire and again following clamping of the wire consists. It is of course necessary that one of the clamping mechanisms is arranged movable on the machine frame, otherwise the wire would be stretched during bending.
    A disadvantage of bending machines of the prior art is that the use of two linear drives of the Beigestößel itself is heavily stressed to bending, which is why this must be relatively large dimensions. Another disadvantage that arises from two linear drives, is that with a structure only certain bending angle are possible. To produce, for example, lattice girders with different geometries, such bending machines of the prior art had to be extensively converted.
    The object of the invention is to provide a bending machine which is designed to save material at the same time and can bend wire in an extended angle range compared to the prior art.
    This object is achieved by a bending machine with the features of claim 1.
    This is done by the plunger is mounted translationally and rotationally movable by a first bearing means and by a second bearing means. With 2/14 other »words, the translatory and rotational bearing always allows the bending plunger to be aligned in the direction of the force that it should exert on the wire. As a result, it is less subject to bending and can therefore be made smaller.
    Another advantage is the extended applicability. Because the additional rotational movement significantly more bending angle can be realized without having to rebuild the Beigemaschine itself before. As a result, it is then possible that a device for the production of lattice girders, the road machine is designed according to the invention, lattice girders of any geometry, as disclosed for example in the Austrian patent application A 174/2013, can be produced.
    The described improvement, which eliminates conversions for different lattice girder geometries, makes it possible to manufacture lattice girders in the JusWn-time process. In other words, these lattice girders can be quickly produced to order and in small economic quantities. Also lot sizes with the quantity 1 are possible. The machine can thus be integrated, for example, in a precast concrete plant and provide the respective required lattice girders immediately before the concreting process. In devices for the production of lattice girders, as they are known in the prior art, this is not possible due to the required conversion work and it always had to be made for a profitable operations larger amounts of the same lattice girders, since the conversion yes costs time and thus productivity.
    Advantageous embodiments of the invention are defined in the dependent claims.
    It is preferably provided that the plunger has a fixed, invariable in operation length. The design can be simplified as a result, since, for example, complex hydraulic cylinders are avoided in the ram itself. 3/14
    In order to optimally exploit lever ratios at the same time and avoid stressing the ram, it may be provided that the first bearing device articulates the ram at an end region of the ram and / or that the second bearing device articulates the ram at an end region of the ram. The end regions should not be more than 20% of a total length of the plunger and of course be counted from one end of the plunger so as not to lose the technical effect.
    The simultaneous translational and rotational bearing of the plunger can be achieved in a particularly simple manner by the first bearing device comprising a crank drive and / or in which the second bearing device comprises a push rod.
    Adapted to these two forms of movement, a first preferably rotary drive for moving the crank mechanism and / or a second, preferably linear, drive for moving the push rod can then be provided.
    In particular, in the lattice girder production, it is advantageous that exactly two bending surfaces are provided for bending exactly two wires, since each lattice girder exactly two curved wires, which are then used as diagonal straps, are needed.
    Protection is further desired for a device for lattice girder production with a bending machine according to one of claims 1 to 7 according to the invention and a welding device for welding diagonal straps made by means of the bending machine with bottom straps and a top chord
    Due to its material properties, steel is the preferred material for lattice girder production.
    Further advantages and details of the invention are apparent from the figures and the associated description of the figures. Show: 4/14 ················································:

    Fig. 6 is a side view of a bending machine according to the invention, the three figures illustrate the flow in a bending process, a perspective view of a bending machine according to the invention, a schematic representation of a device according to the invention for lattice girder production, a side view of a lattice girder to illustrate the different angles and dimensions.
    In the following, reference is made to FIGS. 1, 2 and 3. In this embodiment, the bending ram 2 is mounted on the machine frame 10 via a first bearing device 11 and a second bearing device 12. The first storage device 11 has a crank mechanism 3. The second storage device 12 has a push rod 7.
    After the feed of the wire 1 by the feed device 9, the wire 1 is fixed by the clamping device 4 and the further clamping device 5. This is shown in FIG. By the linear drive 14, which acts on the push rod and the rotary drive 13, not shown, which acts on the crank mechanism 3, the plunger 2, at the free end of which two bending surfaces 6 are moved from below against the wire 1 and bends it thereby. As shown in Figure 2, also the further clamping mechanism must be moved by a linear drive, otherwise the wire would be stretched. It is important that the clamping mechanism is traversed at exactly the right speed, since compression of the wire 1 is also undesirable. Finally, FIG. 3 shows how the bending by the plunger 2 has ended. In this situation, the plunger 2 can be moved downwards again by the first drive 13 and the second drive 14, and the clamping on the clamping mechanisms 4, 5 can be released and the advancement of the wire 1 can take place 5/14 by means of:; d: i © · V0 ^ <b. The bending machine 20 is then ready for a new bending operation.
    FIG. 4 shows a perspective view of the bending machine 20. Here it becomes clear that two wires 1 are bent at the same time. This is particularly advantageous in the manufacture of lattice girders, since the bent wires 1 can then be used as diagonal straps 22, where they are needed in pairs in a lattice girder. As is also apparent from this figure, both the crank 3 and the push rod 7 is executed in a forked construction. The Bückftächen lie on a bolt which is guided both by the ends of the fork-shaped push rod 7 and by a fork-shaped end of the plunger 2.
    FIG. 5 schematically shows a device for producing lattice girders. Supplied are coils 15, on which suitable wire is wound. By unwinding 16 this is unwound and supplied in the case of the upper straps 23 and lower straps 21 of a leveler 17. The one wire for the
    Diagonal belts 22 is determined, the Biegemasehine 20 is supplied.
    The lower chords, the upper chord and the diagonal straps produced in the bending saw 20 are fed together to the welding device 25, in which they are welded to form a lattice girder 24. Appropriately, the lattice girders are then stored in a reservoir 18.
    FIG. 6 shows a side view of a lattice girder. The most important dimensions of a lattice girder can be seen here. These are, on the one hand, the pitch T and the height H of the lattice girder. Also important are the angles und and 3 between the diagonal belt 22 and the bottom flange 21. Unlike the prior art, the bending mass of the invention allows a completely free choice of the parameters T, Η, α and β One of the angles α or β is technically not a problem. Typical values for the height H are 60 mm to 450 mm. Typical values for the pitches T are 150 mm to 250 mm 6/14 ·· ·· ···· ·· ···· «• · · · · · · · · · ·« · · · · · · · · · · · ·
