Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing brush for forming a roll brush for removing slag of a rolled steel plate or the like and polishing the surface.

[0002]

2. Description of the Related Art This type of polishing brush has a channel type polishing brush in which the bases of a large number of brush bundles are sandwiched over the length of a U-shaped band, and a large number of brush bundles are disposed on the outer peripheral edge of a disk. There is a disc-shaped polishing brush formed by bundling the bases and extending the hair tips in a radial direction. The channel-shaped polishing brush is wound around the shaft in a spiral manner, while the disc-shaped polishing brush is a disc-shaped polishing brush. A large number of shaft holes are inserted through the shaft through a shaft hole provided at the center, and each polishing brush is strongly compressed in the axial direction of the shaft and fastened to the shaft to form a roll brush.

[0003]

However, in the conventional polishing brush, when the roll brush rotates at a high speed and comes into frictional contact with the surface of the steel plate, the brush bristles vibrate (chatter) to form horizontal stripes on the surface of the steel plate. There are problems such as sharpening marks (chattering marks), unevenness of the brush density between the turns of the channel brush, and generation of vertical striped sharpening marks (brush marks) due to the formation of winding gaps.

In the above-mentioned channel-type polishing brush, the edge (mouth) of the U-shaped band member strongly presses each brush bundle, and the brush bundle breaks at the pressing portion due to high vibration during operation. On the other hand, in the disk-type polishing brush, the edge (outer peripheral edge) of the disk of each polishing brush strongly presses the brush bundle. There are problems that arise, and their solution is an issue.

[0005]

According to the present invention, as a means for solving the above-mentioned problems, a large number of filaments are densely arranged in parallel, and after the parallel filaments are cured, they are coagulated with a flexible heat-resistant adhesive. A belt-like brush material is formed, and the base of the belt-like brush material is sandwiched by a gutter-like channel made of a U-shaped metal band to form a polishing brush in which a large number of belt-like brush materials are planted over the length of the channel.

Further, a polishing brush is formed in which a large number of the above-mentioned band-shaped brush materials are radially extended from the outer peripheral edge of the disk.

The above-mentioned belt-shaped brush material is formed by arranging a large number of filaments in the band width direction and a plurality of filaments in the band thickness direction.

The above-mentioned polishing brush is wound or penetrated on the shaft, and is strongly compressed from both ends in the axial direction of the shaft and fastened to the shaft to form a roll brush. It is possible to eliminate brush marks and chattering marks at the time of polishing a rolled steel sheet, thereby performing good polishing.

Further, each belt-shaped brush material exhibits a good buffering effect against the above-mentioned strong compression, and can prevent the breakage of the filament and the breakage of the brush material due to the violent vibration during the steel plate polishing.

[0010] Also, just by superposing a plurality of belt-shaped brush materials,
The planting density of the brush material can be easily increased, and effective steel plate cleaning can be performed while causing each belt-shaped brush material to bend.

According to the present invention, the above-mentioned conventional problems of the roll brush are achieved by causing the roll brush to have a good polishing and wiping effect while retaining the above-mentioned breakage preventing effect of the roll brush.

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIGS.

FIG. 1 shows a band-shaped brush material 1. As shown in FIG. 3, the band-shaped brush material 1 has a large number of filaments 1a densely arranged in parallel in the width direction and the thickness direction of the brush material 1. After the parallel filaments have been cured, they are coagulated with a heat-resistant adhesive 2 having a high flexibility, for example, from about 20 mm to about 5 mm.
It is formed with a band width of mm.

In the belt-shaped brush material 1, an adhesive 2 is interposed between the parallel filaments 1a to bond the filaments 1a to each other, and also covers the outer peripheral surface of the belt-shaped brush material 1 to form a coating layer 2a. .

The filament 1a is made of, for example, Conex (trade name), nylon, or the like manufactured and sold by Teijin Limited.
A filament made of a synthetic resin such as polypropylene or a metal, and has a suitable elasticity.
The nylon is a general name of a synthetic high-molecular polyamide,
It is used as a material for forming synthetic fibers, and polypropylene is a high molecular weight polymer of propylene and used as a material for forming plastics and synthetic fibers. These can be suitably spun. In the spinning, preferably, abrasive particles are mixed to form long filament yarns, and a large number of these filament yarns are arranged in parallel in a strip shape and coagulated with the heat-resistant adhesive 2. Is cut into a fixed length to form the belt-shaped brush material 1.

As the heat-resistant adhesive 2, a rubber-based adhesive or the like having a high flexibility after curing is used. Preferably, the polishing effect is obtained by coagulating with the adhesive 2 mixed with the abrasive particles 3. The entire belt-shaped brush material 1 is allowed to flex freely while improving. That is, the belt-shaped brush material 1 is
The elasticity of the filament and the flexibility of the heat-resistant adhesive 2 for bonding the filaments 1a to each other make the filament 1a freely bendable.

As shown in FIG. 2, the above-mentioned belt-shaped brush material 1 is formed by stacking a plurality of belt-shaped brush materials 4 to form a brush material 1 in a roll brush described later.
Can be uniformly and easily increased.

As shown in FIGS. 4 and 5, the laminated band-shaped brush material 4 can be formed into a prism having a substantially square end face by the above-mentioned polymerization, and the base 10 of each band-shaped brush material 1 is bonded to the heat-resistant adhesive. It is joined by a covering portion 11 made of an adhesive having the same or at least the same properties as the agent 2, and the tip side of each band-shaped brush material 1 can be freely bent with the base 10 as a fulcrum.

As shown in FIG. 2, the band-shaped brush material 1 (laminated band-shaped brush material 4) formed as described above is folded in two so as to straddle the core member 5 and the like. As shown in FIG. 7, a channel-type polishing brush 8 or a disk-type polishing brush 9 in which a large number of band-shaped brush materials 1 are implanted by being sandwiched or bound by a gutter-like channel 6 or a disk 7 is formed.

Each of the figures shows, as an example, a channel-type polishing brush 8 or a disc-type polishing brush 9 made of a laminated band-shaped brush material 4, but a single belt-shaped brush material 1 can be applied. This will be described as a brush material 1.

As shown in FIGS. 5 and 6, the metal gutter-like channel 6 and the core material 5 having substantially the same length, for example, a round bar steel material 14 are used.
A large number of belt-like brush materials 1 are straddled and folded in two to raise both ends of the brush material 1, and the two-fold base 10 is interposed and sandwiched in the gutter-like channel 6 together with the core material 5. At this time, the cover of the covering layer 2a of each belt-like brush material 1 prevents the edge 6 'of the trough-like channel 6 from biting into each filament 1a at the edge 6a, and the brush material 1 at the time of steel plate cleaning is removed. Is prevented from being broken.

FIG. 6 shows a double channel type polishing brush 8, in which the trough-shaped channel 6 is used as an outer channel, and the core material 5 is formed by an inner channel 15 having substantially the same length as the outer channel 6. The belt-like brush material 1 is provided in the inner channel 15.
Are folded over a large number, and the folded base 10 is included in the outer channel 6 together with the inner channel 15.

At the edge 6a of the outer channel 6, a large number of claw pieces 6b inclined toward one end of the channel 6 are provided at intervals. The brush material 1 is bent along the inner wall at an inclined angle to clamp the brush material 1 together with the inner channel 15, and as shown in FIG. 6B, polishing a large number of band-shaped brush materials 1 over the length of the outer channel 6. The brush 8 is formed.

In the same manner as described above, the coating layer 2 of each belt-shaped brush material 1
a, the edges 6a, 1 of both channels 6, 15 to the filament 1a forming the belt-shaped brush material 1.
The biting of the edges 6 'and 15' in 5a is prevented.

In the double channel type polishing brush 8 shown in FIG. 6, the brush material 1 is sandwiched at an inclination angle toward one end of the outer channel 6, and the flexibility of the filament 1a forming the brush material 1 itself is increased. By imparting an appropriate bending property to the tip side of the heat-resisting adhesive 2 by the heat resistance and the flexibility of the heat-resistant adhesive 2, the brush material 1 can be ground by rotating the brush material 1 in the opposite direction or in the forward direction. The cleaning is done effectively.

As another example of each of the channel-type polishing brushes 8, as shown in FIG. 10A, the band-shaped brush material 1 is folded in two without using the core material 5, and is planted (pinched) in the channel 6. Alternatively, as shown in FIG. 10B, it is also possible to implant (clamp) the belt-like brush material 1 in the gutter-like channel 6 without folding it.

In the channel-type polishing brushes 8 formed as described above, the covering portion 11 formed by applying the heat-resistant adhesive 2 to the planting base 10 of each band-shaped brush material 1 can be formed. By crimping the rim 6a over the length of the gutter-like channel 6 at the portion 11, as shown in FIG. 8, the covering portion 11 is bitten by the edge 6 'of the rim 6a, and The material 1 is clamped, and the edge 6 'is prevented from biting into each filament 1a forming the belt-shaped brush material 1 in cooperation with the jacket layer 2a.

The channel-type polishing brush 8 formed as described above is spirally wound in the axial direction of the shaft 16 as shown in FIG.
6, the brush materials 1 are strongly compressed from both ends in the axial direction to bring the brush materials 1 into close contact with each other, and are fastened to the shaft 16;
To form

When the channel-type polishing brush 8 is compressed and fastened, the outer layer 2 a of each brush material 1 or the covering 11

The resulting breakage of the brush material 1 is reliably prevented.

FIG. 7 shows a disk-shaped polishing brush 9, which is folded in two while inserting the band-shaped brush material 1 into each of a plurality of brush material installation holes 17 provided at equal intervals on the outer peripheral edge of the disk 7. Then, both ends thereof are extended radially outward from the outer periphery of the disk 7, and as shown in FIG. 7B, the two-folded base portions 10 of the brush materials 1 are formed into small holes 18 formed in the plate surface of the disk 7. A binding wire 19 made of a steel wire or the like is passed through and tightly bound. At this time, the outer peripheral edge 7 'of the disk 7 and the binding wire 19 are prevented from biting into each filament 1a by the cover of the covering layer 2a of each belt-shaped brush material 1, and the brush material 1 is broken at the time of steel plate polishing. To prevent.

Each of the strip-shaped brush members 1 implanted as described above has the flexibility of each filament 1a and the filament 1a.
Due to the flexibility of the heat-resistant adhesive 2 for connecting the two, the brush material portion that can be extended to the outside of the disk 7 can be bent.

As another example of the disk-shaped polishing brush 9, as shown in FIG. 11, a large number of brush material planting holes 17 opened at the outer peripheral surface of the disk 7 are formed at equal intervals. The base 10 of the brush material 1 is fitted and locked in the mounting hole 17, preferably fixed with an adhesive or the like, and the tip side of the brush material 1 is radially extended outward from the outer periphery of the disk 7. Brush material 1
The base 10 has a planting block 23 made of metal or resin.
The planting block 23 is integrated with the planting hole 17.
To be implanted on the disk 7.

In the disk-shaped polishing brush 9 formed as described above, the covering portion 1 is attached to the planting base 10 of each band-shaped brush material 1 in the same manner as the channel-shaped polishing brush 8.
As shown in FIG. 8, the coating portion 11 is made to bite on the outer peripheral edge 7 ′ of the disc 7 so as to form the brush material 1.
And the bite of the edge 7 'and the binding wire 19 into each filament 1a forming the brush material 1 is reliably prevented in cooperation with the jacket layer 2a.

As shown in FIGS. 7 and 13, a large number of the disc-shaped polishing brushes 9 are inserted through the shaft 16 through shaft holes 20 provided in the center of the disk.
The belts 1 are arranged with a pitch shifted in the circumferential direction of the shaft 16 so as to intervene between the band-shaped brushes 1 between the other band-shaped brushes 1, and the polishing brushes 9 are strongly compressed in the axial direction of the shaft 16 so as to be closely adhered. To the same shaft 16,
The roll brush 22 is formed.

In fastening the disk-shaped polishing brush 9, the covering 11 formed on each brush material 1 is attached to the shaft 1.
6 can be applied to the outer peripheral edge 7 ′ of the polishing brush 9 adjacent to the polishing brush 9 in the axial direction to enhance the adhesion, and the strong pressing force can be applied to the coating layer 2 a of each belt-shaped brush material 1.
In addition, the absorption by the covering portion 11 causes a good cushioning effect on the entire roll brush 22. This reliably prevents breakage of the brush material 1 (filament 1a) that occurs at the outer peripheral edge 7 'of the disk 7 due to high vibration during steel plate cleaning.

In the above-described roll brushes 21 and 22, for example, as shown in FIG.
And a laminated brush material 4 'composed of four strip-shaped brush materials 1 are formed, and a channel-type polishing brush 8 or a disk-type polishing brush 9 in which these are alternately implanted is formed. That is, the number of superposed laminated strip-shaped brush members 4 ′ is made smaller than the number of superposed laminated strip-shaped brush members 4, so that the laminated strip-shaped brush members 4 and 4 ′ are alternately arranged in the axial direction of the shaft 16. 16 is wound or penetrated to achieve high density planting of the brush material.
