    The invention relates to a bending machine for wire mesh mats, which consist of flocks of mutually perpendicular crossing, welded together at the crossing points longitudinal and transverse wires.
    Regardless of whether they are offered as single or double bending machines, the automatically available bending machines for wire mesh mats currently available on the market, due to their bending lever geometry, are not able to produce positive or negative bending angles on a wire mesh mat formed from welded longitudinal and transverse wire coulters , In order to bend negative bending angles, the wire mesh mat must be turned several times. For this process a lattice mat turner is necessary. Further, to make a turn clockwise or counterclockwise two main drive units are required, each of which must apply the full bending force.
    The invention aims to provide an improved machine for bending wire mesh mats, which does not require a mat turner and allows for bending the longitudinal or transverse wires of the wire mesh mat with both positive and negative bending angles. The invention achieves this in a bending machine with a machine frame accommodating the bending elements, a wire mesh mat through the bending frame

All bending forces are generated by means of a single main drive unit.
    The invention will be explained in more detail below by way of example with reference to the drawings. 1 to 4 are schematic side views of a bending machine according to the invention in various stages of bending the longitudinal wires of a wire mesh mat, Fig. 5 is a schematic view of the bending machine in the direction of the grid mesh feed, and Fig. 6 is a partial plan view to Fig. 5th
    The bending machine shown has a precision feed device, not shown, which engages positively and non-positively on the wire mesh mat to be bent, e.g. a carriage with clamping elements, and they programmatically in the sense of the arrow P in the Gitttermattenebene E moves through the bending machine. The respective work program is supplied by a program control device, also not shown. In addition, a central drive device is provided for all machine parts to be driven.
    A machine base 13, which can accommodate bending forces in all directions, carries a machine-width extending beam-like receiving device 14 for a series of bending mandrels 1, the servo-controlled by means of an associated hydraulic displacement device 17 (FIG. 6) in the cross-machine direction displaced (arrow P3 in FIG Fig. 6) and in height by means of an associated lifting device 16 'is adjustable (arrow PI in Fig. 5). The number of bending mandrels 1 results from the machine width and the minimum longitudinal wire pitch that is possible on the bending machine. For example, the minimum longitudinal wire pitch is 50 mm.
    Furthermore, a likewise beam-like, extending over the machine width receiving device 15 for one of the first row of mandrels 1 associated second row of bending mandrels 2 is mounted on the machine base frame 13, which is also servo-controlled by means of an associated hydraulic displacement device 19 (FIG. 6) in the cross machine direction displaced (arrow P4 in Fig. 6) and in height by means of an associated lifting device 16 " is adjustable (arrow PI in Fig. 5).
    A third beam-like receiving device 11 is provided on the machine base frame 13 for the bending mandrels 1, 2 associated bending rollers 3, which is also servo-controlled by means of an associated hydraulic displacement device 18 in the cross-machine direction (P6 in Fig. 6) and by means of an associated lifting device 16 within a frame guide 13 'in the height is adjustable (arrow P7 in Fig. 1). The Ver-
    Pushers 17, 18, 19 are actuated by a central drive device, not shown.
    For actuating the bending rollers 3, the bending machine, as shown in FIG. 1, a driven by the central drive device drive shaft 9 for a provided on one side of the machine crank gear 6, which is coupled with a machine width extending over the lever mechanism, which is a bar-like carrier has, the lever 4 'with bending rollers 3 carries. A slider crank G can also be provided symmetrically on both sides of the machine.
    As is apparent from Fig. 1, a connecting rod 20 is connected on the one hand to the drive shaft 9 and on the other hand in a bearing point 10 with the piston rod of a hydraulic cylinder 12 which is mounted on the receiving device 11 and a handlebar 5, the positioning of the bending rollers 3 relative to the respective Bending mandrel 1 or 2 causes.

    Hereinafter, the operation of the bending machine for bending the longitudinal wires 21 of a wire mesh mat in a clockwise upward as shown in FIG. 1 will be explained.
    The row of bending mandrels 1 serves as a bending element about which is bent. The bending row 1 is servo controlled by the associated lifting device 16 '(Fig. 5) in the direction of arrow Pl, depending on the diameter of the longitudinal wires 21, raised to a predetermined height position above the longitudinal wires, and the bending mandrel 1 is then by lateral displacement with the aid of Displacement device 17 (Fig. 6, arrow P3) positioned on the longitudinal wires 21 to be bent.
    The second row of bending mandrels 2 serves as an anvil and is servo-controlled in the direction of the arrow P2, again depending on the wire diameter, by means of the associated lifting device 16 " raised to a predetermined height position below the longitudinal wires 21 to be bent. After the bending mandrels 2 are positioned below the longitudinal wires 21 to be bent, the bending rollers 3 are actuated. The side of the machine base frame 13 arranged hydraulic UmschaltZylinder 12 for the bending lever carrier 4 is retracted so that the handlebar 5 and the connecting rod 20 occupy their retracted position and the beam-like Biegehebelträger 4 with the attached thereto bending levers 4 'and the bending rollers 3, triggered by the not shown central drive device 8 ♦ ♦ · · Φ · φ «·« * Φ φ t · · · Φ «····· · · · via the drive shaft 9 and the crank handle 6, an approximately circular movement of the bending rollers 3 in a clockwise direction ( Circle 8) around the bending element serving as a bending mandrel l causes. The required bending angle is servo-regulated by the program control device.
    The retraction of the beam-like bending lever 4 and the bending mandrel rows 1, 2 takes place in reverse order. The receiving device 11 of the bending lever carrier 4 with the bending rollers 3 moves, driven by the central drive device in the direction of the arrow 7 back to the starting position.
    The bending mandrel row 1 is laterally displaced by means of the displacement device 17 in the direction of the arrow P3 and servo-controlled means of the lifting device 161 lowered down (arrow PI). The bending mandrel row 2 is moved by means of the associated lifting device 16 " also servo-controlled lowered downwards (arrow P2).
    In a subsequent bending cycle shown in Fig. 2 on the grid mesh longitudinal bars counterclockwise upwards (circle 81) - there is no cross wire between first and subsequent bending - only the beam-like bending lever carrier 4 with the bending levers 4 'and bending rollers 3 in the starting position emotional. The bending mandrels 1, 2, however, are only slightly lifted from the longitudinal wires, so that the (not shown) precision feed device, which may be as mentioned servo-controlled carriage with clamping elements, the wire mesh mat can move to the new position in which the bending mandrels 1, 2 again be employed on the longitudinal wires and with the actuated by the bending lever carrier 4 bending rollers 3, the next bend is performed.
    In a further bending of the longitudinal wires in a counterclockwise upward direction - the transverse wires are located between first and subsequent bends - are, as described above, driven for each bending cycle, the rows of mandrels 1, 2 and the bending lever carrier 4 in the starting position and for the subsequent bending between the relevant longitudinal wires 21 re-threaded.
