(57) Abstract:

Use: for the manufacture of wire material. The inventive pornoamatuers block spirals round cross-section located relative to each other on two grid spacing, which are recorded accurately in the guide in the position which they occupy in the finished grid, and are cut to the specified length. Then there is the displacement of the mechanism of formation of spirals on the grid spacing. Is forming another block spirals grid being formed, rotate and continuously sliding with knives mechanism of morphogenesis, woven into the previously formed coil and the first coil previously manufactured fragment of the mesh, moving the guide strictly in the direction of the axes of the spirals. Then the last block of the spirals is cut to a predetermined length and offset of the finished portion of the grid in the direction perpendicular to the axes of the spirals in such a position that the first helix of the finished fragment of the mesh could weave the last spiral newly manufactured fragment of the mesh. 2 Il.

The invention relates to the production of woven metal mesh and allows you to weave fine mesh manufacturer for 8-10.

There is a method of weaving nets of wire helices, consisting in the fact that the mechanism of formation containing auger, made in the form of a sleeve with a continuous helical groove with a pitch equal to the pitch of the helix, and located inside the knife, calibrating the end part which has a cross sectional profile of the spiral, a spiral flattened cross-section, which rotates continuously get away with a knife and intertwined in ready a fragment of the mesh to the specified length, then the formation of the helix is terminated and it is cut to the specified length, then ready a fragment of the mesh is moved to the grid step and the cycle described operations are repeated.

The main disadvantages of this method are the following:

low productivity of manufacturing grid, due to the sequential formation and intertwining spirals (spiral after spiral");

the impossibility of making fine mesh of the circular helix with parameters (d 0.12 mm - 0.4 mm; D 1.2 to 4 mm), suitable for the manufacture of wire material, due to the small stiffness of the helix of fine wire and the absence of a device implementing this method of weaving, accurately fixing the position of the spiral, in which the and adopted for the prototype.

The aim of the invention is to improve the productivity of manufacturing grids and enabling weaving wire mesh, suitable for the manufacture of the wire material.

This objective is achieved in that the method of weaving mesh, comprising forming a spiral, its rotation and in addition ready a fragment of the mesh, thermoabrasion immediately block spirals round cross-section located relative to each other on the two step grid (grid spacing - the distance between the axes of adjacent coils that are located in positions convenient for the mutual interweaving), which is fixed in the guide in this position, and cut to a predetermined length, and then produce a displacement mechanism forming a spiral on the grid step and make the formation more blogosphere, which, being formed, rotate, and continuously sliding with knives mechanism of morphogenesis, woven into the previously formed unit coils in the first coil previously manufactured fragment of the mesh, moving the guide strictly in the direction of the axes of the spirals, then the last block of the spirals cut to a predetermined length and produce the offset of the finished portion of the grid in the direction perpendicular axes Speer is Rahl newly manufactured fragment of the mesh, then repeat the described cycle, and the grid spacing when the stomach is less than the distance between adjacent spirals in the finished grid, when adjacent spirals entered into direct contact with each other.

In addition, in order to obtain mesh with spljusnutymi the cross-sectional profile of the spiral finish grid can be filtered through the rolls, plushevaya it to the specified size and at the same time carrying out the tension of the grid and offset it to the required value.

In the proposed method, a fragment of the mesh is made as if in two steps, and the size of the fragment can be large and are determined by the diameter of the spiral and the number n (the number of spirals in the block) at the same time include spirals, which is only acceptable dimensions of the machine for weaving nets and can be quite large. For example, the length of the fragment coarse mesh (mesh Netting) may be 1.5-2 mm, Therefore, the performance of the proposed method may be several tens of times higher than the performance of the method, taken as a prototype.

Running spirals round cross-section, the exact position holding the first spiral of the finished portion of the grid and n spirals, strmilov the n coils enables the manufacture of wire mesh, suitable for the manufacture of the wire material.

The features distinguishing the claimed technical solution to the prototype, not identified in other technical solutions.

In Fig. 1 shows a diagram of a device for implementing the method of Fig. 2 - a device for weaving nets manually.

Mechanism 1 forming spirals (see Fig. 1) first forming wire 2 unit coils 3 a circular cross-section, which accurately fixed using the guide 4 (shown conventionally) in increments of two grid steps. Fragment 4 grid, made for the previous cycle is set using the displacement mechanism 6 ready-to-fragment of the mesh and the guide 7 in such position that its first helix 8 occupies the position in which it is interwoven with the last coil 9 of the produced fragment of the grid.

Mechanism 1 forming spirals after forming and segments of spirals 3 are shifted through the mechanism 10 to the step of the grid relative to the coils 3. In this position, the mechanism 1 (Fig. 1) and generates the next block spirals 11, which rotates continuously come with knives (Fig. 1 not shown) of the engine 1, weaving in helix 3. After the formation of the new Fraga, the first spiral of the new fragment of the mesh takes the place of the spiral 8.

Then the cycle of manufacturing grid is continuously repeated.

The opportunity for practical application of the proposed method for the manufacture of wire mesh, suitable for the manufacture of wire material, can be easily checked. It is enough to prove the possibility of interweaving one helix 11 once in two spiral 3 accurately fixed in the position which they occupy when the weaving fragment of the mesh.

Were made of steel wire of diameter d 0.35 mm stretched spiral with a circular cross section with diameter D 3,5 mm, And the step of stretching the spiral to be equalled its diameter.

Manually was woven stripe mesh of these spirals width 150 mm (mesh width equal to the length of the helix), which used a simple device (see Fig. 2), allowing to simulate the proposed method.

Two spiral 3 (see Fig. 2) was recorded in the guide 4, made in the form of a channel, in the position which they occupy in the finished grid, with the help of the needles 12. The diameter of the needles is selected so that the needle does not interfere with the intertwining spirals 11, which was woven by hand.

EPolicy time and provides the ability to manufacture wire mesh, suitable for the manufacture of the wire material. (56) USSR Author's certificate N 1463374, CL 21 F 7/02, 1989.

The METHOD of WEAVING NETS, including forming a spiral through the mechanism of formation, in which the helix rotates continuously with sliding knife mechanism of morphogenesis, cut it, shaping subsequent spiral, in which she weaves in the first spiral finish fragment, characterized in that, to increase productivity, net producing and providing weaving wire mesh, carry out simultaneous shaping block spirals with a circular cross section, arranged one relative to another at a distance equal to 2 S, where S is the distance between the axes of two adjacent spirals at the moment of their mutual interweaving, fixed in the guiding element in position, in which they intertwine with adjacent spirals, and after cutting these spirals mechanism of formation of spirals shift distance S and produce the formation of one more unit of spirals, which, moving in the guiding element along the longitudinal axis of the spiral, woven in a spiral previously made unit, and after cutting these spirals ready prietenie the last spiral of the subsequent fragment of the mesh in the first helix of the finished fragment of the mesh.

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.
