Device for the manufacture of wire mesh
(57) Abstract:The invention relates to the manufacture of wire mesh and allows you to improve the mesh quality, and improve the design of a machine for the manufacture of double-torsion. The device comprises a frame, nodes twisting and the drum to draw the grid. Nodes twisting made in the form of forks, two ends of which communicate with reels with wire, and the third end of the plug is connected to a power drive, which is located on the beam, which can be moved on the frame to the left and to the right, the bed is equipped with a power drive mounted with a possibility of vertical travel. 2 Il. The invention relates to the manufacture of wire mesh used in land reclamation, road construction and fencing.A device for the manufacture of wire mesh that contains the nodes twisting in the form of a kinematically interconnected chain transmission spur wheel gearing Novikov, slaves of which has two inclined channels, which are below the diametrical axis, and the upper parts of these channels pass through the cavities of teeth spaced from each other by at least 1.5 step, while caprices driven gears mounted for rotation in fixed on the carriage covers (ed. St. N 1304967. CL B 21 F 27/02, 1984).The disadvantage of this design is the low quality of the generated mesh. Each twist is formed Of V - shaped hole in the center of the twisting. The twist produced in different directions, which unnecessarily annoying metal (wire) and galvanizing, or otherwise coating can deviate from the base material (wire). The machine has a low productivity.Thus, the object of the present invention is to improve the quality wire mesh and improving the design of the machine.The problem is solved in that the nodes twisting made in the form of forks, two ends of which communicate with the coil and wire, and the third end of the plug is connected to a power drive, which is located on the beam, which can be moved on the frame to the left and to the right, the bed is equipped with a power drive mounted with a possibility of vertical travel.In Fig. 1 shows a frame 1, which can move up and down by means of hydraulic cylinder 2 along the guide rails 3,4. On the frame 1 of the strengthened beam 5, which can move left and right by means of the hydraulic cylinder 6. On beam 5 fortified actuators 7,8,9,10, which rotate the fork 11,1212 - in the coils 17 and 18, the plug 13 at 19 and 20, and the plug 14 at 21 and 22, the coil 23 in the moment. The grid 24 is pulled by the drum 25, which has made the cut on the configuration of the grid.In Fig. 2 is the same as in Fig. 1, but the beam 5 by means of the hydraulic cylinder 6 is moved to the right on the grid spacing, and forks 11,12,13 and 14 interact with the coils 16-17, 18-19, 20-21, 22-23, respectively.The proposed device operates as follows.Includes actuators 7,8,9 and 10 through plug 11,12,13 and 14 start to rotate coils 15-16, 17-18, 19-20, 21-22, respectively (coil 23 at this time is free). When actuators 7,8,9 and 10 will make the specified number of turns (usually two) and the wire coils will make two cables, coils engaged by the grippers or be in special nests (Fig. not shown), and the bed 1 by means of the hydraulic cylinder 2 goes down and with it goes beam 5, which are actuators 7,8,9 and 10 and plug 11, 12 and 13, and 14, up until the fork 11,12,13 and 14 will not be released from the holes in the coils 15-16, 17-18, 19-20, 21-22. After that, with the help of the hydraulic cylinder 6 beam 5 with the power wires 7,8,9 and 10 and plugs 11,12,13 and 14 moves to the right on the same grid spacing. Cylinder 2 raises a frame 1 and a beam ilıca 12 - with reels 18-19, fork 9 - coils 20-21, and the plug 14 with the coils 22-23. The coil 15 at this time is free (Fig. 2). Includes actuators 7,8,9 and 10, the wire of the coils makes a specified number of twists. Column 1 goes down, beam 5 moves to the left of the fork are included in the appropriate coil (Fig. 1), and the process repeats.The finished net is stretched drum 25, which is made corresponding notches on the configuration of the grid.The advantage of this construction lies in the increased quality of the grid, the machine advances over the device. Device for the manufacture of wire mesh that contains a frame, the nodes twisting and drum for pulling the grid, characterized in that the knots twisting made in the form of forks, two ends of which communicate with reels with wire, and the third end of the plug is connected to a power drive, which is located on the beam, which can be moved on the frame to the left and to the right, the bed is equipped with a power drive mounted with a possibility of vertical travel.
SUBSTANCE: invention is related to protective nets, intended for reinforcement of slope against fall, and to methods of their manufacturing. Net is made with diagonal plaiting and is woven of twisted wire strands bent in the shape of spirals, armature bundles or cords, which comprises two or more wires or twisted wire strands of steel. Method for manufacturing of protective net consists in the fact that twisted wire strand, cord or armature bundle is fed with a certain angle of lift at least to one bending mandrel of device and is bent at a certain length around bending mandrel approximately by 180°, then repeatedly moved along their longitudinal axis to bending mandrel at a certain length, bent accordingly around bending mandrel by 180° until this twisted wire strand, cord or armature bundle does not achieve shape of spiral, besides wire strand bent in the form of spiral, cord or armature bundle are woven together with the second twisted wire strand, cord or armature bundle bent in the form of spiral, and this is repeated until net is made with diagonal plaiting of desired value.
EFFECT: optimal fixation of slope is achieved, as well as damage danger is reduced.

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.
