UA74704C2 - Method for manufacture of grid for fences and grid for fences - Google Patents

Abstract

Invention relates to working of metals by pressure. Grid for fences contains the rows made of closed wire rings connect together with interlacing of the rings of adjacent rows. In the grid each ring of adjacently located in each row rings is passed through the next ring, and each ring from lower- and upper-located row with respect to the central row is passed simultaneously through two adjacently located and interlaced rings of central row. Each ring is made of the turns of one section of wire twisted between them. Invention ensures the increase in the form stability of grid, its bearing capacity.

Description

Description of the invention

The invention relates to the processing of metals by pressure, in particular to the construction of wire mesh cloths, and can be used to obtain chain mail cloth used as barrier fences, for example, as a protective net against falling stones.

There is a well-known net for fences, which contains rows made of closed wire rings, connected to each other by interweaving the rings of adjacent rows (ZY, Auth. svid. Mo 475202, B21E 31/00, publ. 09/16/1975).

The disadvantage of this grid is due to the fact that it is made by unfolding 70 spiral springs in one plane with subsequent interweaving of turns between adjacent rows. With this manufacturing technology, the grid has the possibility of deformation in width and length due to a change in the geometry of the ring, which is unacceptable for barrier systems.

In addition, the used method of manufacturing the mesh is low-tech, because during the process of forming the rings, the spring coils are deformed, which lowers the load-bearing capacity of the coil in the mesh. 12 The specified well-known decision was adopted as a prototype for the declared objects.

This invention is aimed at solving the technical problem of making a grid of rings made as separate elements, woven in an original way both in each row and between rows.

The technical result achieved in this case consists in increasing the form-retaining mesh and its load-bearing capacity while ensuring the maximum possible reduction in weight.

The specified technical result for the method is achieved by the fact that in the method of manufacturing a grid for fences, which consists in forming rows of closed wire rings due to the mutual interweaving of the specified rings in each row and the rings of the same row with the rings of an adjacent row, each ring of adjacently located in in each row of rings is passed through a ring located next to it, and each ring from the lower and upper rows in relation to the central row is passed simultaneously through two s 22 adjacently located and intertwined rings of the central row, while in the manufacture of rows Go) of intertwined rings and interweaving of rows between each ring is made from one piece of wire by forming a base coil of a ring from a piece of wire, which is passed through an adjacent ring, and winding the remaining part of the wire around the base coil.

The specified technical result for the device is achieved by the fact that in the mesh for fences, which contains M, rows made of closed wire, made in the form of separate elements of rings, are connected to each other by interweaving the rings of adjacent rows, each ring of adjacently located rings in each row is omitted through the adjacent ring, and each ring from the lower and upper rows in relation to the central row is simultaneously passed through two adjacent and intertwined rings of the central "I" row, while each ring is made of twisted turns of one wire segment. 3o The specified features for each of the declared objects are essential and interconnected with the formation of a stable set of essential features sufficient to obtain the required technical result.

This invention is illustrated by a specific example, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result with the given set of features. "

In fig. 1 - shows the general view of the grid for barriers. WITH

According to the present invention, the grid for fences contains rows made of closed wire rings 1, interconnected by interlacing the rings of adjacent rows. Each ring 1 is made as a separate element, which is made by weaving one piece (segment) of wire around the first (basic) turn of the same wire. The ring is a piece of wire wrapped many times around the first turn of this wire.

The end of the wire is inserted into a metal crimped sleeve. The ring is formed at the same time as the mesh is woven, so each ring cannot be separated from the mesh. To separate the ring from the mesh, it must be unwoven. and Each ring 1 from adjacently located rings in each row is passed through an adjacent ring, and each ring from the lower and upper rows in relation to the central row is simultaneously passed through two adjacent and intertwined rings of the central row. 7 The grid is made as follows. at 20: First, the first ring is woven on the machine. The first turn of the wire is made and then the remaining part of the same wire is wound around the first turn. The rest of the wire is cut. Next, into the already finished ring

T" weave the next ring due to the production of another segment of the wire woven into the first ring of the first turn, around which the remaining part of this wire is wound. In this way, the first row of interwoven rings is made. Next, the rings of the first row are individually woven into the rings of the second row, etc. 29 With such interweaving, the shape retention and load-bearing capacity of the net increases significantly when it is justified

GF) minimum weight parameters. The net withstands a large dynamic load due to the high strength of individual rings, each of which is an integral element of the net, as well as due to the large surface friction against the wire inside the ring.

This invention is industrially applicable, as it can be manufactured using simple 60 technologies used in the production of metal woven meshes.
