Description

[Detailed description of the invention] This invention uses an aluminum clad wire, which is made by cladding aluminum to a uniform thickness on iron wire or mild steel wire, as a core wire.
The present invention relates to a barbed wire constructed using an aluminum wire or an aluminum alloy wire as a side wire.

As is well known, barbed wire refers to thin wire with barbs that is strung around pastures, fields, and other land, and in the past most wires were mainly made of iron wire.

However, such barbed wire has the following unavoidable drawbacks due to the use of iron wire as a constituent material.

(a) First of all, it is easy to rust.

This phenomenon was unavoidable not only with bare iron wire that has not undergone any treatment, but also with iron wire that has been plated with zinc or the like.

In particular, the cut ends of the side wires that make up the barbs directly expose the bare iron wire even in galvanized wires, so rust is noticeable from these parts.

(b) Second, it is heavy.

In other words, the iron metal itself has a very high specific gravity, which increases the overall weight of the barbed wire and causes various adverse effects.
For example, handling during transportation is inconvenient, and supporting members need to be quite strong during use.

The present invention aims to solve the above-mentioned drawbacks of conventional barbed wire, and its characteristics are that aluminum wire or mild steel wire is uniformly clad with aluminum as the core wire. The main feature is that aluminum alloy wire is used as the side wire.

Next, one embodiment of the present invention will be described with reference to the drawings.

First, a long iron wire or mild steel wire is clad with aluminum to a uniform thickness by various known methods to obtain an aluminum clad wire.

Then, this aluminum clad wire is used as the core wire 2 as a single wire or a twisted wire.

Next, the aluminum or aluminum alloy wire is formed to have barbs to form the side wire 3, and the barbed wire 1 is manufactured using a known barbed wire manufacturing apparatus.

In the case of this embodiment, two core wires 2 are used, and while twisting these two core wires 2, 2, the side wire 3 is wound around both core wires 2, 2 at regular intervals, cut, and the sharp cut ends are turned outward. It is something that stands out.

By constructing the barbed wire using the above-mentioned materials, the corrosion from the side wire, which has been a problem with conventional methods such as the tendency to rust, can be avoided by using aluminum wire or aluminum alloy wire for the side wire 3. Since I used it, there was no problem at all.

In addition, there was no problem in terms of strength as long as the wire diameter and other factors were selected.

Moreover, compared to conventional products, it can be expected to last nearly twice as long due to rust.

In addition, since the core wire 2 is made of aluminum clad wire, which is made by cladding iron wire or mild steel wire with aluminum to a uniform thickness, it can be made several times thicker than simple aluminum plating, so the strength of the aluminum layer is increased. Since the wire is large, even if the wire is damaged during twisting, it will not reach the underlying metal, so problems such as corrosion will not occur from there.

Moreover, the problem of decrease in mechanical strength no longer occurs.

Compared to conventional galvanized iron wire, it is 5 to 6 resistant to rust.
You can expect twice the lifespan.

Furthermore, when steel wire is used, since its tensile strength is high, the problem of wire breakage that occurs with conventional iron wires can be eliminated.

Furthermore, since such barbed wire uses aluminum wire or aluminum alloy wire for the side wire 3, the weight of the product can be reduced to about 60% compared to conventional galvanized iron wire.

As described above, according to the present invention, it is possible to provide an excellent barbed wire that is lightweight and has excellent corrosion resistance.
