Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of manufacturing a welded wire mesh panel for a fence, which is mainly used as an inclined fence installed on a slope.

(Prior Art) Conventionally, welded wire mesh panels used as sloped fences installed on slopes, etc., are made by arranging a large number of vertical metal wires and horizontal wires at a preset angle, and then Each intersection was welded together to form a parallelogram panel.

(Problem to be Solved by the Invention) However, in this conventional manufacturing method, the wire rods are crossed at a preset angle and then the crossing portions are welded, so once welded, it is difficult to adjust the crossing angle between the wire rods. This has the disadvantage that it is difficult to obtain panels that are suitable for the site, such as the slope where it is installed.
Moreover, when manufacturing panels suitable for various slopes, it is necessary to arrange a large number of wire rods by setting the intersecting angles of the wire rods at various angles in advance, making it difficult to produce a wide variety of products in small quantities.

(Means for Solving the Problems) In order to solve the above problems, the method for manufacturing a welded wire mesh panel for fences according to the present invention provides a grid in which a large number of vertical metal wires and horizontal wires are arranged substantially perpendicularly at predetermined intervals. A welded wire mesh standard panel is prepared in advance in which the wires are arranged in a shape and the intersections of the wires are welded. Rotating force is forcibly applied to each intersection in parallel with the panel surface, plastically deforming the wire and deforming the lattice network.

(Example) The present invention will be described below with reference to the drawings.

A connecting bar 15 substantially orthogonal to the bars 14, 14...
15 by a pin 16 so as to be rotatable. That is, as shown in FIGS. 3 and 4, the mold 6 is arranged so that the holding molds 7 and 8 face each other so that the insertion grooves 9 and 13 are inside and the holding bars 10 and 14 intersect with each other, and the connecting bar 11 , 15 are rotatably and detachably connected by a connecting pin 17.

In the manufacturing method of the present invention, the standard panel 1 is first held between the holding molds 7 and 8 of the mold 6 as shown in FIGS. 2 to 4.

The standard panel 1 is fitted between the holding molds 7 and 8 by being fitted into the fitting grooves 13 of the standard panel 1, respectively, and the body edges 5 and 5 are held by protruding outside the mold 6.
Next, while holding the standard panel 1 between the holding molds 7 and 8, a rotating force parallel to the panel surface of the standard panel 1 is applied to the mold 6, thereby deforming the mold 6 into a parallelogram shape as shown in FIG. Then, the standard panel 1 is plastically deformed by simultaneously applying rotational force parallel to the panel surface to each of the intersection parts 4, 4, etc. in the mold 6, and the first

The welded wire mesh standard panel 1 has vertical wire rods 2 and horizontal wire rods 3 welded together in a grid pattern, and does not have a body edge portion 5. The manufacturing method in this case is to hold the entire standard panel 1 between the holding molds 7 and 8 of the mold 6 and mold it in the same manner as described above.

In addition, in the case of the above figures 1 to 9, standard panel 1

The standard panel 1 may be formed according to the site where it will be installed as a fence. Furthermore, in the mold 6, the ends of the holding bars 10, 14 of the holding molds 7, 8 may be fixedly pinned to predetermined positions of the connecting bars 11, 15, respectively; If the standard panel 1 is slidable along the crosspieces 11 and 15, when holding the standard panel 1 in the mold 6,

Although it is designed to correspond to the vertical wire rods 2 and horizontal wire rods 3 of the standard panel 1, extra holding bars 10 and 14 may be provided. We can respond even if things change. Further, the holding bars 10 and 14 of the holding molds 7 and 8 have fitting grooves 9 and 13 so as to be able to hold the vertical wire rod 2 and the horizontal wire rod 3, but the holding bars 10 and 14
may have a structure in which the vertical wire rod 2 and the horizontal wire rod 3 can be clamped and held, respectively.

FIG. 11 is a plan view showing the state before panel molding, FIG. 12 is a front view of the same, FIG. 13 is a side view of the same, and FIG.
15 are plan views showing the state after panel molding, respectively.

In FIGS. 10 to 15, 1 to 4 indicate the same parts as in FIGS. 1 to 9. A mold 18 is composed of a plurality of divided molds 19, 19, . . . . In the split mold 19, short holding bars 21 having grooves 20 for vertical wire rods 2 are arranged in parallel at predetermined intervals, and one end of the holding bars 21, 21...
A pin 23 is attached to the connecting bar 22 which is almost perpendicular to 1, 21...
On the other hand, a holding bar 25 having a fitting groove 24 for the horizontal wire 3 faces the connecting bar 22, and a holding bar 21,
21..., and both ends of the holding bar 25 and the connecting bar 22 are rotatably and detachably connected to each other by a connecting pin 26.

As shown in FIG. 11, the split molds 19 of the mold 18 are arranged in correspondence with rows of intersecting portions 4, 4, . . . that are continuous in the lateral direction of the standard panel 1.

In this manufacturing method, the standard panel 1 is held by each split mold 19 of the mold 18 as shown in FIGS. 11 to 13. Specifically, one vertical wire 2 of the standard panel 1 is divided into each intersection 4, and the horizontal wire 3 is inserted into the insertion groove 20 of the holding bar 25.
The standard panel 1 is held by being fitted into each of the panels 4 and 4. Next, while holding the standard panel 1 in the mold 18, a force parallel to the panel surface of the standard panel 1 is applied to each divided mold 19. In the case of FIG. 14, a force is applied to each split mold 19 simultaneously or sequentially in the direction of the arrow to deform the entire mold 18 into a parallelogram shape. Then, the standard panel 1 is plastically deformed by applying rotational force to each of the crossing portions 4, 4, . . . in parallel to the panel surface. Further, in the case of FIG. 15, an example is shown in which the standard panel 1 can be deformed in various ways by adjusting the force applied to each split mold 19.

Further, the manufacturing method of the present invention is not limited to the above-mentioned method, and for example, it is possible to produce uniform intersections by arranging a jig or the like to apply power simultaneously or sequentially to each intersection 4 of the vertical wire rod 2 and the horizontal wire rod 3 of the standard panel 1. Any method may be used as long as a rotational force is applied to 4 in parallel to the panel surface. Furthermore, in the present invention, the standard panel 1 may be deformed after being painted, or may be deformed before painting, but it is better to deform it after painting, since the painting equipment that is compatible only with the standard panel 1 in the painting manufacturing line is This is preferable because it only needs to be installed, and the drying oven can be made more compact than when dealing with deformed panels.

(Effects of the Invention) As detailed above, in the manufacturing method of the present invention, after a standard welded wire mesh panel in which vertical wire rods and horizontal wire rods are approximately perpendicular to each other is prepared in advance, each intersection of the vertical wire rods and horizontal wire rods is parallel to the panel surface. Since rotational force is applied by adjusting the rotational force, the intersection angle of the wire rods can be easily adjusted by adjusting the rotational force, and it is also possible to easily obtain a panel suitable for the site where it is installed, such as a slope. Moreover,
It can easily handle high-mix, low-volume production.

In addition, since it is manufactured from a standard welded wire mesh panel in which the vertical wire rod and the horizontal wire rod are almost orthogonal, it is easy to procure materials, and it is also possible to easily manufacture a variety of panels without having to keep many types of inventory as in the past. It is also possible to make it cheaper in terms of cost.

Furthermore, since the standard panel is plastically deformed after being painted, the painting production line only needs to be adapted to the standard panel, making the drying oven more compact than when painting conventional deformed panels. I can do it.
