The invention relates to the manufacture of wire mesh used in land reclamation and road construction the holding frame, the feeders, tension and direction, pulling and forming drums wires, nodes, twisting and wires from twisting elements in the form of driving through a common chain drive gears, which are provided with inclined channels, which are below the diameter of the wheel axis, and the upper parts of these channels pass through the cavities of teeth spaced from each other by 1.5 step, means to restrict the twisting and winding mechanism of the finished grid.

The disadvantage of the design is its complexity, for laying wires in binding sites need to raise and lower the platform with the binding sites.

This design does not provide a reliable contact wires in binding sites, especially the second series of nodes twists. Therefore, the operator has to guide the wire into the binding sites manually, which may take up to 10% of the time, which reduces the productivity of the machine.

The task to be solved by the invention is the improvement of the design of the machine and reliable packing of wires in binding sites.

The problem is solved in that the device has installed between nodes twisting its step, and the nodes are twisting and means for limiting zone twist is installed on the fixed frame, while the frame has wedges on the number of nodes twists and mounted for movement introduced into the guiding device mounted at an angle to the frame.

The invention is illustrated by drawings, where: Fig.1 shows the diagram of the machine; Fig.2 - mechanisms of twisting frame and actuator nodes twists, and Fig.3 - frame support Assembly of Fig.3A is the same, side view; Fig.4 is a device top view when the frame is up and the wires are not laid in binding sites; Fig.5 is a device top view when the frame is at the bottom and closer to the second row of twists and wire laid in binding sites.

Where 1 - fixed frame, 2 - drawing reel, 3 - forming drum, 4 - oil station, which includes a motor, a pump, a radiator to cool the oil with fan, safety valves and fittings /hoses, tank, etc./, 5 - marking device where the coil wire, 6 - limiters twists, 7 is the first number of binding sites, 8 - second number of binding sites, 9 - frame, 10 - wedge-shaped teeth for extension wires (Fig.3), 11 - slider rigidly attached to the frame 9 under some is by hinges 13 (Fig. 3) attached to a support 14, which in its upper part overlaps (in the drawing) the bar on the frame 9, below the teeth 10 (at the same height as the upper part of the support strap 14) on the side view of Fig.3 - marked by the dotted line. To support 14 deviated only by a specified amount between the frame 9 and the support 14 attached limiter (flexible) 15, the support 15, the support 14 is deflected from the frame 9 under its own weight and if that's not enough, it is possible to establish between them the spring. Frame 9 moves up and down along the guide rails 12 by means of hydraulic cylinder 16 (Fig.1). To support 14 is not touched for a second number of binding sites 8 attached strip 17, in which the bearing 14 slides when moving up or down, strips 17 may be one or two. The drive of the first and second number of binding sites 7 and 8 are in the form of hydraulic cylinders 18 and 19 of the gear racks (Fig.2) 20 and 21, respectively. To the coil with the wire unwinding device 5 does not spin spontaneously, provided the brake 22. The grid 23 is pulled by the drum 2 and is wound on the drum 3, which have a power actuator in the form of an electric motor or hydraulic actuator (Fig. not shown).

The proposed device operates as follows.

Wire unwinding of CDCP these wires go from the unwinding device 5 to the twisting, located near the drum 2. In Fig.4 shows that the divergence of the wires goes smoothly from twisting near the drum 2 to the unwinding device 5. However, the residual stress in the area of twisting wires (near drum 2) makes the divergence angle of the smaller wires. Wire converge in the middle between the two rows 7 and 8. So get the wedges 10 between the wires, in order to move them apart and they got into binding sites of the second series of nodes twisting seems to be problematic. Wire remain separated only near the first row of binding sites 7 and get the wedges 10 are the most acceptable (and this forms the focus of this proposal). The wedges 10 are between the wires, the frame 9 with the wedges 10 and support 14 moves downward along the guide rails 12 on which slide the sliders 11 and is closer to the second number of binding sites 8, the wedges 10, pushing the wire (as if combing them), close to the second row of binding sites 8, and wire fall into binding sites (Fig.5). Bearing 14 when lowering the frame 9, by interacting with the strip 17, is close to the frame 9. When produced twisting wires in the first 7 and second 8 rows of binding sites, the hydraulic cylinder 16 raises the frame 9 up and it along the guides 12, including floaters, 11, rises up and od is the wires, the cycle repeats. The finished grid is pushed out frame 9 up, and to pull the net out of the second row 8 twisting nodes and the desired bearing 14, which pushes it out anywhere between 7 and 8 rows of twisting knots, depending, as adjusted (by length) flexible rod 15, bounding the deviation of the bearing 14 from the frame 9. The grid 23 is pulled by the drum 2 by a specified amount.

The proposed device has the following advantages - frame, moving diagonally, reliably gets wedges 10 between the wires and the operator does not have to manually correct wire, which increases machine productivity by 10-15%, you can automate the process of tying the grid.

SUBSTANCE: invention relates to machine building and may be used for producing braided gauzes. Proposed method comprises forming first unit helices by set of blades to preset length at preset pitch and expending them by expansion mechanism in helix axes to preset pitch defined by claimed relationship. forming second unit helices by second set of blades arranged opposite the first set at opposite side of produced gauze with shift relative to first unit helices through gauze pitch to ensure preset pitch in continuous rotation of helices. Said helices slide from blades to get braided into expanded helices of the first set to make gauze fragment. Length of said helices is selected appropriately. First unit helices are released from expansion mechanism and shifted to open the zone. Second unit helices are cut in said zone to cut finished gauze fragment to be displaced for connection with the next fragment. Gauze next fragment and connection helix are made, for the latter to be braided in the last helix of the next fragment and to the first helix of previous fragment over the entire length of all helices. Cycle is reiterated unless required length of gauze is produced.

EFFECT: production of fine gauzes.
