The invention relates to the processing of metals by pressure, in particular to devices for the manufacture of wire mesh.

The aim of the invention is to increase productivity and simplify the design of the device.

FIG. a flowchart of the device is depicted; in fig. 2 - device, general view; in fig. 3 - twisting knot, general view; in fig. 4 is a diagram of a cam mechanism for changing coil positions; in fig. 5 — node 1 in FIG. 3

The device for making wire mesh consists of a bed 1 on which coils 2 wires, supports 3 blocks are located. Wire twisting assemblies 4 are made in the form of blocks, each of which includes a stationary tubular guide 6 supplied with a spring-loaded conical sealer 5 twist, passing inside a screw gear through P1esteren 7 and 8 from the electric motor 9 through the gearbox 10 and the brush 9 with the electric coupling 12 installed on frame 1, section 13 with tapered seats 14 on the flanges 15 and clamps 16 for gripping and securing the mandrel 17 with the coil 18. The mandrel 17 is capable of reciprocating movement for changing positions by means of a cam mechanism, consisting of the stop rod 19 and cam 20, with which electrofusion 21 interacts, rods 22 with protrusions 23 and 24 acting on clamps 16 located on the axis and locking element 25. Command On the operation of the electric couplings 12 and 21, a Nipper 26 screw is cut on the shaft with gears 8 by means of a slider 27, which includes end switches 28 and 29 mounted on the base 1.

The grid is pulled by drum 30 with teeth 31 attached to it, which serve to form the cells and hold the grid. The drum 30 receives the drive from the electric motor through a double-flow reducer 32. Through the same reducer, the drum 33 receives the drive, against which the product roller 34 is pressed with a load 35, and on which the finished mesh is wound.

The device works as follows.

One row of wires from coils 2 through spring-loaded tapered seals 5, not 10

The electric motor 9, which, through a gearbox 10, by means of a chain transmission and gear 11 with an electric coupling 12, rotates gear 8, with which gears 7 of spindle drive 13 of block 4 are engaged. The twisting process begins.

When the shaft of gears 8 rotates on which the Nipper screw is cut (having three turns by the number of twists), the slider 27 moves to the right and turns on the limit switch 29 in the extreme position, which by means of the electric coupling 12 stops further rotation of the blocks. The limit switch 29 includes an electric motor, which, through a double-flow reducer 32, begins to draw the net with the drum 30 and winding onto the product roller 34 with the drum 33, and the electro-coupling 21, which interacts with the cam 20, to drive it into rotation. Under the action of the cam 20, the rod 22 with its protrusions disconnects the latches 16 and moves the mandrels 17 with the rollers 18, which are fixed in the adjacent blocks 4 in order to twist with the wires of the neighboring blocks. At the same time, the slider 27 reaches the extreme left position of the Nipper screw 26 and turns on the limit switch 28, which disables the electrofusion 21 to move the pole 22; an electric motor that stops the broaching and winding of the finished mesh through a double-flow reducer 32 and turns on the electromotive 12 to begin twisting the wires of the neighboring blocks, thereby repeating the cycle.
