Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a method for manufacturing a material for a strong metal brush used for polishing and grinding various hard members or removing adhered members such as burrs. This invention is used in industrial fields that manufacture, sell, and use metal brushes of this type.

(Prior art) Conventionally, this type of metal brush material has been made by bundling a large number of metal filaments and flocking this bundle, or, in the case of a rotary polishing brush, by drilling holes around the brush mounting plate. The above-mentioned bundle is inserted into the provided brush mounting hole and bent to be installed. However, if each metal wire is a straight linear body, variations may occur, so operations such as flocking, insertion, and bending are required. In addition, polishing, grinding force, or peeling force is weak, and clogging occurs during polishing.

Therefore, at present, for example, as disclosed in Japanese Utility Model Application Publication No. 59-49411, after a bundle of metal wires is continuously subjected to zigzag (wavy) refraction, the outer periphery of the bundle is wrapped with steel. Efforts are being made to solve the above-mentioned drawbacks by winding the wire in a spiral.

(Problem to be Solved by the Invention) However, after continuously forming zigzag-like bends in a bundle of metal wires as described above, a wrapped steel wire is simply wound in a spiral shape around the outer periphery. In the case of the material of the constructed metal brush, there are the following problems.

(b) The process of bending the bundle of metal wires in a zigzag pattern and the process of winding the wrapped steel wire in a spiral around the outer periphery of the bundle are performed in separate processes, so production Efficiency is low.

(b) Since the wrapped steel wire is simply wrapped around the outer periphery of the bent bundle, and is not bent at the same place as the bundle at the same time, its holding force against the bundle is weak; If it is used under harsh conditions like a metal brush, the convergence body will come apart in a short period of time, resulting in a lack of durability as a metal brush.

The present invention was developed in response to the above-mentioned problems, and the present invention is a metal brush material that does not cause the bundle as a metal brush material to come apart at all, and therefore can reliably solve the above-mentioned problems. The purpose is to provide a manufacturing method for.

(Means for Solving the Problems) In order to achieve the above object, the method for manufacturing a metal brush material according to the present invention includes feeding a bundle of metal wires toward a refracting mechanism that refracts them in a zigzag shape. a step of wrapping the required number of metal wires in a spiral around the outer periphery of the bundled body when feeding the bundled body to bind the bundled body, and feeding the bundled body to the refraction mechanism. , a step of continuously forming a zigzag-shaped bent part on the bundle and the wrapped metal wire at the same time, and with this bent metal wire wrapped,
It is characterized by tightly holding and bundling a focusing body bent in a zigzag shape.

(Function) According to the method for manufacturing a metal brush material according to the present invention, the bundle of metal wires is first wound in a spiral shape with metal wires on its outer periphery without going through the steps described above. and are temporarily tied together.

Next, when the bundle passes through a refraction mechanism, both the bundle and the metal wire that make up the bundle are refracted in an orderly zigzag pattern, and as a result,
The bundle is tightly bound with metal wires and will not come apart.

(Example) Hereinafter, an example of the present invention will be described based on an example of an apparatus schematically shown in the accompanying drawings.

In Fig. 1, R ₁ and R ₂ are reels each having a through hole 1 in the center and a guide ring 2 in the flange, and are arranged on the same axis with a required interval. Yes, although not shown,
It is configured to be adjustable and rotated at a desired speed in opposite directions via a motor or the like. Furthermore, long metal wires 3 made of hard steel wires of about 0.2 to 0.3 mmφ are wound in opposite directions on each of the reels R ₁ and R ₂ .

G ₁ is a gear with teeth at a required pitch arranged horizontally behind the reels R ₁ and R ₂ on the axes thereof, and G ₂ is arranged vertically further behind the gear G ₁ . One set or two sets of these gears constitute a refraction mechanism 4 that refracts a bundle of metal wires in a zigzag shape as described below. .

5 is a bundle of a large number of the metal wires 3, and 6 is a gear.
A guide roll 7 is placed behind _G2 , and a winding drum 7 is placed behind the guide roll, and the winding drum 7 is rotated at a required speed by a motor (not shown). It is composed of

Next, an embodiment of the present invention using the apparatus configured as described above will be described.

First, a bundle 5 of a large amount of metal wires 3 (not shown) prepared in advance on the left side as viewed in FIG. 1 is reeled.
It is inserted into each through hole 1 of R ₁ and R ₂ , and then only between the first opposing gear G ₁ that constitutes the bending mechanism 4, or between the first and second opposing gears G ₁ and G ₂ (in this embodiment, between both gears), and then passed through the guide roll 6, and then the winding drum 7
Wrap it around.

Next, after inserting the wound metal wire 3 wound around one or both of the reels R ₁ and R ₂ (both reels in this embodiment) through the respective guide rings 2, by appropriate means. They are wrapped around the bundle 5 from opposite directions before the first opposing gear _G1 . In this state, when the winding drum 7 is rotated at the required speed and the reels R ₁ and R ₂ are rotated at the required speed in the direction of the arrow (opposite direction),
The metal wires 3 wound around both reels R ₁ and R ₂ are spirally wound around the surface of the bundle 5 from both the left and right directions, and the bundle is wrapped around the bundle 8.
In this state, it is sent to the refracting mechanism 4 side together with the focusing body 5, and when passing between the first opposed gears _G1 ,
It is bent continuously in a zigzag shape in the vertical direction, and then bent in a zigzag shape in the left and right direction when passing between the second opposed gears _G2 . At this time, since the bundle 5 and the wrapped metal wire 3 are simultaneously bent in a zigzag shape, the bundle 5 is tightly held and bound by the wrapped metal wire 3, and the bending mechanism 4 The metal brush material is fed out and wound up by the winding drum 7 to continuously obtain the desired metal brush material.

The metal brush material B manufactured through the above manufacturing process has the form shown in 4 in FIG. 2, but in the above manufacturing process, one reel _R1
(or R ₂ ) and one opposing gear G ₁ (or G ₂ ), a metal brush material B having the form shown in 1 in FIG. 2 can be obtained. In addition, in the above manufacturing process, both reels R ₁ and R ₂ and one opposing gear G ₁
(or G ₂ ) alone, a metal brush material B having the form shown in 2 in _FIG .
R ₂ ) and both opposing gears G ₁ and G ₂ are used to
A metal brush material B having the form shown in 3 in the figure is obtained.

Metal brush material B manufactured as above
This is because not only the bundle 5 is bent in a zigzag shape, but also the wrapped metal wire 3 is bent at the same location, so that the bundle 5 is tightly held and bound. It does not come apart at all and can produce various effects as described later.

Note that the metal wire may be not only the hard steel wire mentioned in the above example, but also stainless steel wire, brass wire, and other materials that are strong and have high wear resistance, elasticity, and toughness. If there is one, it can be selected and used as appropriate.
The zigzag-shaped refraction mechanism is also not limited to that of the above embodiment.

Furthermore, when forming two types of zigzag-shaped bending parts in the left-right direction and horizontal direction in the convergence body using the two gears G ₁ and G ₂ , the arrangement interval, arrangement angle, tooth pitch, etc. of both gears should be adjusted. By making appropriate adjustments, it is possible to continuously and orderly form zigzag-shaped bent portions that differ in direction at equal intervals.
