Abstract

PURPOSE:To obtain a nice-looking net on which a regular pattern has been repeated exactly without a dimension error, by arranging many formed wires in the vertical direction and the horizontal direction, and fitting the formed wire being orthogonal to a recessed part of each formed wire, to said part, respectively. CONSTITUTION:In each formed wire a' which has been placed in the vertical direction and the horizontal direction, and has been provided with a flapping 111 of a prescribed shape, a recessed part 91 is formed at every prescribed interval. By fitting the formed wire a' being orthogonal to the recessed part 91 of each formed wire a', to said part, a insetwined net A of a different waved- shaped can be obtained. In this way, it becomes that which has repeated a pattern having no error, and also since the wire is fitted into the recessed part, the strength is good.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a method for forming a recess into which a wire can be fitted in the axial direction of one wire, by forming a recess into which a wire can be fitted, by performing second shaping (corrugation) in a direction perpendicular to the axial direction. The present invention relates to a braided network made of formed wire and a wire forming method.

[Conventional technology]

Arrange many corrugated wires vertically and horizontally,
When the intersection points are fixed together to form a single mesh, this is known as a crimp mesh.

[Problem that the invention seeks to solve]

In this case, the corrugated work involves feeding out the wire intermittently,
When the wire is stopped, a wave pattern is applied to the wire, but it is extremely difficult to accurately form the regular wave pattern without dimensional errors. Especially if the wire is long (
The more errors they made, the more they accumulated, and the resulting net was in extremely bad shape, with defects that made it unsuitable for commercial use.

The main purpose of the present invention is to obtain a good-looking net in which regular patterns are accurately repeated without dimensional errors, and to complete a wire forming method that does not cause cumulative errors even when using particularly long wires. be.

Another object of the present invention is to simplify the mechanism by corrugating the wire while continuously feeding the wire, and to complete a method for forming the wire almost automatically and efficiently by increasing the feeding speed. This aims to reduce molding costs and minimize capital investment.

[Means for solving problems]

The net of the present invention is characterized by forming recesses into which wires can be fitted at predetermined intervals in the axial direction of the wire, and second molding is performed at predetermined intervals in the direction perpendicular to the axial direction. , a large number of wires are arranged in the vertical and horizontal directions, and the wires are braided by fitting the molding wires perpendicular to the recesses of each molding wire into the respective recesses. Further, the forming method of the present invention is characterized in that convex portions are formed at least at predetermined intervals on the outer circumferential surface of one wheel, and concave portions are formed at least at predetermined intervals on the outer circumferential surface of the other wheel, facing each other. A recess that is large enough to press the wire by a pressing pin that reciprocates in the direction of the rotational axis of the other wheel in synchronization with the rotation of one of the pair of wheels provided, and to fit the wire into that part. A first forming step of forming the wire in the axial direction, and a second forming step of forming the wire fed between the two wheels in a corrugated direction perpendicular to the axial direction by rotating the pair of wheels synchronously. It's about repeating.

[For production]

In the net of the present invention, recesses are formed at predetermined intervals in each of the molded wires arranged in the vertical and horizontal directions, and the molded wires perpendicular to the recesses are fitted into each recess to form a single mesh. ing. However, each formed wire is formed with corrugations at predetermined intervals, so that meshes having various shapes when viewed from a plane are formed, and are excellent in design.

On the other hand, in the wire forming method according to the present invention, convex portions are provided at predetermined intervals on the outer circumferential surface of one of a pair of wheels, and concave portions are provided at predetermined intervals on the outer circumferential surface of the other wheel so as to face each other. The wire to be formed is fed between the pair of wheels, but there is a pressing pin that reciprocates in the direction of the rotational axis of the other wheel in synchronization with the rotation of one of the wheels. The wire fed between the pair of wheels is formed with recesses at predetermined intervals in the axial direction into which the wires can be fitted. In addition, by synchronously rotating a pair of wheels, a convex portion and a concave portion provided so as to face each other on the outer peripheral surfaces of both wheels allow the wire fed between the pair of wheels to be placed in a predetermined direction perpendicular to the axial direction of the wire. Wave forming is performed at each interval. Both the corrugated forming and the forming of the recess into which the wire can be fitted are performed at predetermined intervals without any deviation.

〔Effect of the invention〕

The braided network according to the present invention has a wire perpendicular to one wire inserted into the recessed part of one wire at the intersection of the vertical direction and the horizontal direction, so it is advantageous in terms of strength compared to a wire that is simply crossed. Furthermore, when a single wire is braided with a recess that allows the wire to fit into it and a wave pattern that is regularly formed, the braided network will repeat the pattern without any errors, Not only does the product value improve accordingly, but it can also be extremely superior both in terms of design and industry.

Further, according to the forming method of the present invention, it is possible to form a concave portion and a wave pattern to the extent that the wire can be fitted into one wire by regular pinching without any cumulative error. In the second forming process (wavy pattern) in which the wire is formed in a direction perpendicular to the wire, there is no cause for cumulative errors due to a timing difference with the first forming process in which the recess into which the wire can be inserted is formed, and the periodic and accurate Patterns can be formed. Note that the first molding step of molding a recess into which the wire can be fitted is replaced by the second molding step of molding in a direction perpendicular to the axial direction (wavy pattern).
By performing this process earlier, it is possible to form an excellent wire with an undeformed wavy pattern.

In addition, if a wire forming device is designed based on the wire forming method of the present invention, the wire can be corrugated while being continuously fed out, so the feeding speed can be increased due to the simple mechanism. In addition, it has the advantage that many types of braided nets can be provided by simply changing the outer peripheral shape of the pair of wheels and the number of pressing pins.
