Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel three-dimensional welded wire mesh board manufacturing apparatus. More specifically, as will be clear from the detailed explanation below with reference to the attached drawings, a flat welded wire mesh 1 is formed into a corrugated shape by a corrugation device 11, and a corrugated mesh 3 is formed, and a large number of straight lines are arranged in parallel above and below the corrugated mesh 3. The vertical wires 2 are sent to the welding device 12, and the welding device 12 welds the contact portions of the corrugated mesh 3 and the vertical wires 2 to form a three-dimensional welded wire mesh 4, which is then loaded with a porous body 6 to form a flat plate. Three-dimensional welded wire mesh board as 6
This invention relates to manufacturing equipment for manufacturing.

For example, when forming a corrugated product made from a metal plate or a synthetic resin plate, even if a processing phenomenon such as shrinkage, elongation, or drawing occurs in a part of the product, large areas adjacent to the part may shrink. A desired waveform can be obtained by considering that the area can be changed gradually.

On the other hand, when a flat welded wire mesh 1 is formed into a corrugated shape by the corrugation device 11, the vertical lines 7 of the welded wire mesh 1 are suddenly pulled, and in addition, the horizontal lines 8 welded to the vertical lines are The welded wire mesh 1
Moreover, the formed corrugated mesh 3 tends to recover to its original state before forming by the time it reaches the welding device 12 for forming the three-dimensional welded wire mesh 4 due to residual stress. There are problems such as.

The present invention solves these problems: (1) the welded wire mesh 1 is supplied to the corrugating device 11 after being cut and still has some slack; A clamping means 13 for holding down the wire mesh 1 or 3 on the delivery side and/or a waveform maintaining feeding device 15 having a waveform 14 that follows the waveform so that the waveform mesh 3 is fed to the welding device 12 while maintaining the waveform. By providing the

In other words, the "sudden tensile force" in item (a) above is applied to the cut free end side of the feeding side of the cut welded wire mesh 1 relative to the position of the corrugating device 11 (see Figure 2), or The welded wire mesh 1 on the feeding side is distorted by the corrugation device 11'', because it is transmitted little by little to each of the slackened welded wire meshes 1 (see Figure 1) and absorbed. B. The sending side of the wave guide device 11 of the "sudden tensile force" in item (a) above is completely blocked by the clamping means 13, or (at the same time) is transmitted to the waveform 14 and absorbed. , and furthermore, the "residual stress" in item (b) above also applies to the clamping means 1.
3 and the waveform maintaining/feeding device 16, reducing the residual stress.In addition, the porous body 6' also acts synergistically, resulting in excellent strength and shape and dimensional accuracy. Three-dimensional welded wire mesh board with high commercial value 6
is obtained.

It is something.

Furthermore, according to the manufacturing apparatus of the present invention, the conventionally used multipolar electric resistance welding machine 34 can be used as is for manufacturing the C-welded wire mesh 1, and the corrugating device 11 and the clamping means 13 are added to this. and/or a waveform maintaining and feeding device 16, a straight vertical line feeding device (coil stand, bobbin 18, 19, conveyor (not shown), etc.)
, efficient continuous integrated production is possible with a manufacturing equipment that requires relatively small capital investment, such as a welding device 12 for manufacturing three-dimensional welded wire mesh and a porous material loading device 20, etc. It is possible to provide a three-dimensional welded wire mesh board 6 at a low price.

Moreover, the three-dimensional welded wire mesh 4 and the three-dimensional welded wire mesh board 6 manufactured by the manufacturing apparatus of the present invention have excellent strength because the corrugated mesh 3 forms a truss on the construction palm. It is possible to reduce the weight of the three-dimensional welded wire mesh 4 used, and the three-dimensional welded wire mesh board 6, which is made into a flat plate by loading the porous body 6, is lightweight and has the general properties of the porous body 5. It also has excellent thermal and sound insulation properties, and can be sprayed with mortar or plaster on its surface, or depending on the application, materials with high moisture-proofing and water-stopping effects can be mixed into the porous body 6, mortar or plaster to achieve the desired properties. A three-dimensional welded wire mesh board 6 is obtained.

There are advantages such as

An embodiment of the apparatus for manufacturing a three-dimensional welded wire mesh board according to the present invention will be described based on the accompanying drawings.

FIG. 1 is a side view showing an embodiment of the present invention, FIG. 2 is an enlarged side view showing a corrugating device, and FIG. 3 is a side view showing another embodiment of the corrugating device and the corrugating device. be.

As shown in Fig. 1, a welded wire mesh manufacturing apparatus using a multi-pole electric resistance welding machine that has been conventionally used is such that vertical wires 7 wound around a large number of coil stands 9 are straightened by a straightening machine (not shown). ) to remove the curls and straighten it into a straight line, and supply it to between welding electrodes 35 and 36, which are provided one pair above and below for each line of the multipolar electric resistance welding machine 34, while the straightening machine (not shown) A large number of horizontal wires 8 cut to a predetermined size are stored in a stocker 37 after being straightened by a straight line (omitted), and a horizontal wire dropping device 38 drops one at a predetermined period to a welding position on a vertical line T. made to fall;
Then, the upper welding electrode 36 is lowered and the upper welding electrode 3
5 - lower welding electrode 36 - each intersection of the vertical line 7 and the horizontal line 8 is welded by passing current between them. When welding is completed, the welded wire mesh 1 is fed out, the vertical wire 7 from the coil stand 9 is let out to the welding position, and the horizontal wire 8 is dropped. In this way, vertical line 7 and horizontal line 8
A flat welded wire mesh 1 in which the wires intersect in the shape of a base grid is manufactured.

The welded wire mesh 1 manufactured in this way is processed up to the corrugating device 11,
Either feeding with slack as shown in FIG. 1 or cutting and feeding as shown in FIG. 2 is selected. In FIG. 1, 10 is a bit (groove),
A space large enough to accommodate the slack portion of the welded wire mesh 1 is required.

In order to maintain this slack, it is preferable to match the feeding of the welded wire mesh 1 with the feeding device (not shown) and the feeding device portion (conveyor) 16 of the waveform maintenance feeding device 15. This method is suitable for continuous integrated production and for managing the entire production system. In FIG. 2, 39 is the shearing force of a shear (shearing machine), and when the completed welded wire mesh reaches a predetermined size, it is preferable to detect this and lower the shearing force 39 so that it is sheared. The sheared welded wire mesh 1 of a predetermined length is conveyed to the corrugating device 11 by a conveyor 40.

The Namiite 1 device 11 uses the press method shown in Figs.
There is a corrugated roller method as shown in the figure. Although various types of press molds are possible, a combination of a chevron mold 22 that reciprocates up and down and a fixed valley mold 23 is common sense. In the press method, it is preferable to provide a clamping means 13 for holding down the wire mesh on the delivery side of the corrugating device 11. Clamping means 13
It also consists of an upper die 24 that reciprocates up and down and a fixed lower die 26.

The lower die 26 may also be allowed to move up and down.

By welding or temporarily welding the corrugated net 3 and a large number of straight vertical lines 2 in the corrugating process or clamping process, the manufacturing system can be improved because the waveform maintaining and feeding device 15 and welding device 12, which will be described in detail later, can be omitted. is simplified. Therefore, the corrugating device 11
The chevron-shaped mold 22 and the valley-shaped mold 23 and the upper mold 24 and lower mold 215 of the clamping means 13 are made of a copper-based material with good conductivity (chrome copper or I) so that they can be used as welding electrodes that can conduct electricity.
When using iron-based materials (such as chrome plating on various high-hardness steels for molds, stainless steel, etc.), take measures to improve conductivity (conductivity). (A thin plate with good electrical conductivity is attached to the surface, or a surface treatment such as plating is performed to cover the surface with a hard and highly conductive material.) Or temporary welding is performed as long as a specified welding strength is sufficient. However, it is preferable to select a method in which a welding process is then performed again.

The corrugated net 3 is constructed according to the above-mentioned proposal, that is, by using welding electrodes that can conduct electricity through the chevron-shaped mold 22 and the valley-shaped mold 23 of the corrugating device 11 and the upper mold 24 and the lower mold 26 of the clamping means 13, and the corrugating process. Except for the method in which a three-dimensional welded wire mesh 4 is formed by simultaneously performing a connecting process at It is necessary to provide a feeding device 16. The waveform maintaining/feeding device 15 is a conveyor type having a waveform 14 along the waveform on the lower side and/or the upper side as shown in FIGS. A method with attached rollers is considered. In the corrugated roller system, each roller 2θ, 27, 28, and 29 can serve as the corrugation device 11 and the corrugation maintaining and feeding device 16. That is, the first pair of rollers 26,27 and the second pair of rollers 28
By providing a drive source (not shown) that rotates at the same speed as the waveform net 3, the waveform network 3 can be fed in addition to the functions of waveform shaping and waveform maintenance.

The corrugated mesh 3 is fed between two pairs of welding electrodes, a movable electrode 30.32 and a fixed electrode 31.33, which are configured to be reciprocally movable in the vertical direction of the welding device 12.

Above and below this waveform net 3, there are coil stands and bobbins 18.
．． A large number of parallel straight vertical wires 2 are sent out from the welding electrode 19 and straightened into straight lines by removing their curls by a straightening machine (not shown), and are simultaneously fed between the two pairs of welding electrodes. In this way, the part where the corrugated net 3 and the direct vertical line 2 that are fed into the welding device 12 come into contact with each other is the welding device 1
2 moving electrodes 30 and 32 are moved forward, and this moving electrode 3
0.32 and the fixed electrode 31.33 are welded by applying electricity to form a three-dimensional welded wire mesh, and then the movable electrode 30.32 is moved back and welded by the size of the mesh to form a three-dimensional welded wire mesh. The shaped welded wire mesh 4 is sent out to the right in FIGS. 1 to 3, and then the next welding process begins.

The three-dimensional welded wire mesh 4 thus formed is sent to the porous material loading device 20, and the porous material is ejected from the nozzle 2OA of the nozzle 2OA to be successively filled with the porous material. The three-dimensional welded wire mesh board 6 can be obtained by cutting this into predetermined dimensions using the shearing force 21 of a cutting device. Examples of porous materials include plastic foam materials, lightweight cellular concrete, mineral fibers, glass fibers, and various types of (verite, perlite and gypsum) plasters. In this case, for the purpose of reducing costs, various materials such as Portland cement, concrete lightweight aggregate (ALA), natural lightweight aggregate, and industrial waste (such as blast furnace slag) may be mixed into the porous body, or adhesives and Desired materials may be mixed in to improve performance such as water resistance.
