Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a wire rod fence.

[0002]

2. Description of the Related Art Fuences are manufactured from various materials, and wire fluences formed by combining relatively small-diameter wires among them are widely used. This wire rod fence is generally formed by welding a vertical wire rod and a horizontal wire rod in a lattice shape so as to be substantially orthogonal. Although this wire rod fence is light in weight and light in appearance, its strength is relatively weak, so that it is common to attach a rim to the upper and lower ends. However, there is a problem that the lightness of the appearance is lost or the assembling operation is complicated due to the waist edge. Therefore, as shown in FIG. Processing, forming a cylindrical part at the upper and lower ends,
Fuens without the rim is proposed and is now on the market and widely used. The wire grid fence proposed by the applicant of the present application eliminates the need for a rim, maintains a light feeling, and is also excellent in strength, but the portion excluding the upper and lower cylindrical portions is the same as the conventional wire grid fence. Since it is merely a line grating, the strength of this portion is insufficient, and there is a problem that the thickness is not sufficient and the appearance is inferior. In order to solve such a problem, the present applicant has proposed a fence in which a horizontal wire of a lattice fence is alternately bent in a thickness direction to form a folding screen.

[0003]

However, in the case of a screen-shaped fence, the vertical wire is not coplanar as a flat wire lattice fence, so the end of the vertical wire is bent into a cylindrical shape or the like. There was a difficult problem. Conventionally, the method of bending the upper and lower ends of the vertical wire material in advance, combining with the horizontal wire material, and then alternately bending the horizontal wire material has been adopted. However, there are drawbacks such as difficulty in processing, troublesome processing, long processing time, and high processing accuracy. An object of the present invention is to remedy the above-mentioned disadvantages of the prior art.

[0004]

In order to achieve the above object, in the method of manufacturing a wire rod fence according to the present invention, ends of a plurality of wires not arranged on the same plane are extended by a predetermined length. Forming an extension portion, bending at least a part or all of the extension portions of the plurality of wires to position the extension portion on the same plane, and forming the extension portion on the same plane; The part is subjected to predetermined processing. According to this method, the processing can be performed after the extension portion is once positioned on the same plane. Therefore, even when the vertical wire is not positioned on the same plane, the processing can be easily performed with high accuracy. become. The processing is generally bending processing, and the end of the fence is processed into a cylindrical shape, a rectangular tube shape, a triangular tube shape, or the like to enhance the strength of the fence body and replace the body edge. Is also possible. Further, a step of attaching another member to the extension portion located on the same plane may be further provided. For example, a step of providing a reinforcing horizontal wire or the like can be added. Further, in the invention according to claim 4, the vertical wire and the horizontal wire are combined in a lattice shape, and at least one end of the upper and lower ends of the vertical wire is extended to form an extended portion to form a fence body. ,
The horizontal wire is bent alternately in the thickness direction to make the fence body corrugated, and at least a part or all of the extending portions of the plurality of wires are bent so that the extending portions are on the same plane. , Processing the extension located on the same plane,
It is characterized by the following. With this configuration, it is possible to easily process the upper and lower ends of the folding screen-shaped fence obtained by alternately bending the horizontal wire into a wave shape. As this processing, it is possible to bend the extension part after fixing the reinforcing material to the extension part, and it is possible to easily manufacture a cylindrical trunk portion or the like.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4, a method of manufacturing the fence shown in FIGS. 3 and 4 will be described. FIG.
Although only the upper end of the fence is shown in FIG. 4, the lower end may have the same shape as the upper end, or may have another shape.

In FIG. 3, the horizontal wire 2 is alternately bent in a wave shape by a smooth curve, thereby forming a folding screen-shaped fence. The vertical wire 1 is mounted on the vertex of the waveform and the slope in the middle of the waveform, the vertical wire 1a at the vertex is bent from the center, and forms the same plane with the vertical wire 1b located on the slope, and this plane is bent. By the torso 50
Is formed.

The manufacturing method will be described in order with reference to FIGS. In FIG. 1, a left side perspective view and a right side view are shown. Here, for the sake of simplicity, an example in which bending is performed at the upper end is shown, but the present invention is not limited to this.
Only one of the upper and lower ends may be used, or both the upper and lower ends may be bent. First, as shown in FIG. 1A, a vertical wire 1 and a horizontal wire 2 are combined in a grid and welded to form a flat grid fluence. At this time, a projecting portion 10 is formed by projecting the upper end of the vertical wire 1 from the horizontal wire 2 by a predetermined distance. In addition, the length of the protruding portion 10 is alternately set to be longer or shorter in accordance with the length of a bent portion 11 to be described later.

Next, as shown in FIG. 1B, the horizontal wire 2 is alternately bent into a wave shape in the thickness direction to obtain a folding screen-shaped fence. For the bending into a corrugated shape, various conventionally known methods can be used. The bending process shifts the position of the vertical wire 1 in the thickness direction, and the vertical wire 1 is not located on the same plane. As shown in (B), there is a vertical wire 1a located at both ends in the thickness direction and a vertical wire 1b located at the center.

Next, the vertical wire 1a is bent to the position of the vertical wire 1b, thereby forming a bent-up portion 11.
a and the vertical wire 1b are positioned on the same plane. This is the state shown in FIG. This processing can be easily realized by using ordinary press processing or the like. Further, the protruding portion 10 is provided with a length in consideration of the length of the bent portion 11 as described above, and the upper end portion of the protruded portion 10 is aligned at the time of performing the bending process.

When the vertical wire 1 is positioned on the same plane as described above, predetermined processing is performed. In this embodiment, (D)
As shown in FIG. 5, six reinforcing wires 3 are welded to one side of the protruding portion 10 in the lateral direction.

FIG. 2 is an enlarged perspective view of this state. As can be seen from this figure, the protruding portion 10 of the vertical wire 1a is moved toward the center in the thickness direction by the bent portion 11 and forms the same plane F together with the protruding portion 10 of the vertical wire 1b. And the strength is strengthened by the reinforcing wire 3 to form a single flat lattice. Processing of such a flat lattice is extremely easy, and a conventional ordinary processing method can be applied as it is.

In this embodiment, the protruding portion 10 forming the same plane F is bent into a circular shape to form a cylindrical body edge 50. This state is shown in FIGS. This bending process is exactly the same as the process of forming the waist edge in the conventional manufacturing of the wire grid fence with the bent waist edge shown in FIG. 6, and the same apparatus can be applied in the same process as it is.

As described above, according to the manufacturing method of the above-described embodiment, a flat grid is formed once in a folding screen fence and then bent into a cylindrical shape. The apparatus and process can be adopted as they are, and there is an effect that the body edge 50 can be formed easily and with high accuracy.

In the above-described embodiment, an example is shown in which bending is performed in a circular shape on the same plane F. However, the present invention is not limited to this, and any bending can be performed. For example, a triangle or a quadrangle can be used. Further, as shown in FIG. 5, a process of merely providing the reinforcing wire 3 on the front and back may be used to make a bending angle.

[0015]

As described above, according to the method for manufacturing a wire rod fence of the present invention, it is possible to relatively easily and accurately perform a predetermined processing on the extended portion.
