The disadvantage of all known solutions is that each element of the fence fencing is attached separately, which makes the production process of each section difficult and lengthy. In addition, the decorativeness of the fence is limited only by the shape of the fence profile and it is not possible to carry out the fence with a pattern inside. These well-known solutions are made welded from straight sections of all-metal bars or shaped pipes. Such products are cheap, but ugly and the quality of their manufacture greatly depends on the professional qualifications of the workers.

There are also solutions that are fences welded from forged elements [http: //xn--80aaagn7aeafyyji.xn--plai/Ogradki/; http://kovka-vladimir.ru/ogrady/eskizy-kovanyh-ograd]. These products are beautiful, but expensive. For their high-quality production, workers of even greater qualification are required than for the technologies described above.

It is also known to manufacture a span of the fence by cutting it entirely with a CNC plasma cutter from a sheet of metal [http://vilas-yug.ru/galery.php?id=6; publ. 03/15/2016]. This solution allows us to produce exclusive products of consistently high quality. The solution is chosen for the prototype.

The disadvantage of this technology is the high cost and, as a consequence, the inaccessibility of such products to the general population. In addition, the fence section is large in size and not convenient to install and transport. The inconvenience and difficulty in installing the section of the picture in the span between the supports of the fence lies in the fact that with a long span the decorative element must be fixed to the support. At the same time, 1 or 2 people at the time of welding should hold the decorative element of the fence with their hands until it is fixed in at least 2 places above and 2 below. This technology also requires cutting the entire span pattern, which is why a lot of metal goes into waste and the area of the consumed material is equal to the span.

The present invention is based on the solution of a problem that allows to simplify the process of creating and assembling metal fences while maintaining wide decorative capabilities.

The technical result provides a simplification of the technological operations of obtaining a section of the fence with the ability to create a variety of forms of decorative elements. In addition, the invention allows the assembly of the fence and its installation in place by only 1 person, which simplifies the transportation of the elements of the fence and its compactness, and this reduces the need for the use of trucks to transport the fence. It also saves metal consumption in the manufacture of the fence section.

The specified technical result is achieved due to the fact that the claimed method of production of metal fences, characterized by the manufacture of a decorative element of the span of the fence by cutting it with a CNC plasma cutter from a sheet of metal, fastening the decorative element of the fence to the support, characterized in that the frame of the fence is made of two round metal profiles , or U-shaped, or rectangular section, the ends of which are pre-bent, and then both parts of the frame are welded with each other; each decorative element of the span of the fence is formed from two identical parallel curves that form the edges of the edge of the detail of the decorative element; the ends of each decorative element are then welded to the upper and lower parts of the frame, forming the desired pattern inside the span of decorative elements.

According to the second variant, a method for the production of metal fences is claimed, characterized by manufacturing a decorative element of the span of the fence by cutting it with a CNC plasma cutter from a sheet of metal, attaching the decorative element of the fence to a support, characterized in that the frame of the fence is formed by bending into a closed loop from a solid metal round profile, or a U-shaped or rectangular section, then both parts of the frame are welded with the ends with each other; each decorative element of the span of the fence is formed from two identical parallel curves that form the edges of the edge of the detail of the decorative element; the ends of each decorative element are then welded to the upper and lower parts of the frame, forming the desired pattern inside the span of decorative elements.

When cutting with a CNC plasma cutter from the sheet of metal, the edges of one part of a decorative element form the leading edge of the next part.

Preferably, the welding process of all elements of the span of the fence is carried out at the place of its installation.

A metal fence consisting of a metal frame and a fence placed inside the decorative element of the span, previously cut with a CNC plasma cutter from a sheet of metal, characterized in that the fence frame is made of two metal profiles of a round, or U-shaped, or rectangular section, the ends of which are pre-bent wherein both parts of the frame are welded together; each decorative element of the span of the fence is formed of two identical parallel curves that form the edges of the edge of the detail of the decorative element; the ends of each decorative element are welded to the upper and lower parts of the frame.

The implementation of the invention

The invention is implemented using plasma cutting technology for sheet metal by a CNC machine in the manufacture of metal fencing.

This technological solution allows you to create inexpensive in production, but at the same time beautiful metal fences of the roadway, lawns, front gardens and ritual purposes.

The fencing frame is made of two metal profiles of circular, or U-shaped, or rectangular cross-section, the ends of which are pre-bent (see Fig. 1), for example, on a bending machine, and then both parts of the frame are connected with each other (see Fig. . 2) and brew. Only such profiles retain sufficient rigidity during bending.

According to the second embodiment of the method, the fencing frame is formed by bending into a closed loop from a solid metal profile of a round or U-shaped or rectangular section, then both parts of the frame are welded with the ends with each other.

CNC plasma cutting machine produces decorative elements 3 of a special shape (see Fig. 3). The shape of these elements 3 is specially designed for their most dense stacking on a sheet of metal to be cut. Further, these elements are welded inside the metal frame 1, made of two profiles of a U-shaped or rectangular section, performing a supporting function. The ends of 2 parts 1 of the frame are pre-bent, and then both parts 1 of the frame are welded with the ends 2 to each other. A round, U-shaped section or a rectangular section of the profile provides the strength of the supporting structure.

Thus, a high price / quality ratio is achieved (any decorative pattern and low cost of the product).

What is new is that not the entire span (or the whole pattern) is cut entirely on the CNC machine, but separate decorative elements 3 of the same shape are made and they fill the space inside the span with a repeating pattern.

The essence of the technical solution is in the form of decorative elements 3, which is composed of two identical curves that form the front and rear edges of the part. This allows, by cutting the trailing edge of one part, thereby forming the leading edge of the next. Thus, the maximum yield of decorative elements from a sheet of metal is achieved and, as a result, a significant reduction in the cost of production, reduction of waste.

Let us consider the details by the example of manufacturing the decorative element shown in FIG. 4. During the cutting process, only one cutting path is used (see Fig. 5). Following one after another, such cutting paths form an array of parts (see Fig. 6). A sample of sheet cutting of 1250 mm to 2500 mm of such parts is shown in FIG. 7. As you can see, there will be very little waste from the sheet.

By the same principle, a variety of decorative elements for fences can be made. Examples of their manufacturing options are shown in FIG. 8.

Examples of finished products are shown in FIG. 9.

Due to the fact that each decorative element is individually welded to the frame, only 1 person can assemble and install the fence on the spot, since the individual elements of the fence do not represent any significant weight. Due to the fact that (see Fig. 3 (a)) the individual elements of the fence are small, the disassembled fence can be easily transported by passenger transport, which simplifies the transportation of the fence elements and its compactness, reduces the need for using freight vehicles to transport the fence.
