Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wire for a rotating brush used for removing rust from metal surfaces, removing paint, and the like.

[Conventional technology]

Various types of wire brushes, such as beher type, cup type, and foil type, are used for removing rust from metal surfaces, removing paint, polishing welded areas, etc., depending on the purpose.

FIG. 3 shows an example of a conventional wire brush, in which the bases of a large number of wires A are bundled and fixed to a rotating member B in an annular shape. The rotating member B is attached to a drive device (not shown),
The wire A rotates at a high speed of about 10,000 revolutions per minute, and as it rotates, it presses against the object to be polished, such as metal or concrete, and performs polishing.

The wire A used in such conventional wire brushes is made of a thin straight metal wire with appropriate hardness, and a large number of metal wires are aligned to a certain length and the base is connected to the rotating member as described above. They are arranged and fixed in a ring shape at B.

[Problem that the invention seeks to solve]

The wires used in conventional rotating brushes are thin as mentioned above (and have moderate hardness), so the wires can break in the middle or from the base due to contact friction with metal or concrete grade GF polishing bodies. Due to the high-speed rotation, broken wire pieces would fly off into the surrounding area due to centrifugal force, and since the wire itself was thin, there were many accidents where the broken wire pieces could get stuck in the body of the worker directly or people in the vicinity, making it extremely dangerous.

[Failure to solve the problem]

SUMMARY OF THE INVENTION In view of the various problems with the wires used in conventional brushes, an object of the present invention is to provide a wire that is flexible, strong, and unbreakable.

To achieve this objective, the wire of the present invention is characterized in that the surface of a single long metal core material is integrally covered with a plurality of braided metal wires.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the wire according to the invention.

The wire 1 in this embodiment has an east linear core material 2 integrally covered with a fully flexible reticular wire material 3.

The eastern linear core material 2 is made by wrapping a single metal wire 5 around the outer peripheral surface of a plurality of thin metal wires 4 along the length of the wires 4 and converging them, as if they were a single ward. It is formed on the core material.

The surface of the core material 2 is covered with a mesh wire 3 formed by braiding a plurality of metal wires, and the core material 2 and the mesh wire 3 are integrally connected.

To knit the net-like wire material 3, it is possible to use a conventional device for knitting cloth 'IJ strings' such as shoelaces and "tsusuri strings" used for W type binding.

That is, while the long core material 2 described above is continuously transferred to the center of a known knitting device (not shown), a plurality of metal wires are rolled up onto the outer surface of the core material 2, About 8 to 10 wire rods are used to form the mesh wire rod 3.

Furthermore, there is no limitation on the way the wires grow, as long as the multiple metal wires cover the outer peripheral surface along the length direction of the intersecting C'' joint 1 and the core material 2 and are integrated as a whole. good.

As the east linear core material 2 and the 1)4 foreshadowing material 3, conventional wire rods can be used, and other thin metal wires having appropriate hardness can also be used.

FIG. 2 shows another embodiment of the invention, in which the same parts as described above are given the same reference numerals.

In this embodiment, the core material 2 is characterized in that a plurality of thin straight metal wires 4 are twisted together to form a single stranded wire, and the surface of the core material 2 is integrated with a mesh wire material 3. The coating is the same as in the previous example.

The wires 1 shown in each of the above embodiments may be cut to the same length, and a large number of wires 1 may be arranged and fixed in a ring shape to a known rotating member, or each wire 1 cut to the same length may be fixed to a known rotating member. It may be folded in half and the folded portion may be fixed to a rotating member.

〔Effect of the invention〕

The present invention has the above-mentioned configuration, and by covering the surface of one long core material 2 with a mesh wire material 3 and integrally bonding the core material 2 and the wire material 3, a large number of metal wire materials 4 and wire materials can be formed. The three elements work together and cooperatively to provide flexibility and moderate stiffness, and will not break even when pressed against the object to be polished at high speed rotation.

Furthermore, since each wire 1 is formed of a large number of thin metal wires, the contact FM between the end face of the wire 1 and the gFIW object is
The friction becomes good, and the polishing efficiency can be improved.
