Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil brush for extrapolating a roll to form a rotating roll brush.

[0002]

2. Description of the Related Art A channel brush is formed by holding a base portion of a brush material in a channel, and the channel brush is closely spirally wound to form a coil brush. 2. Description of the Related Art There is known a rotary roll brush formed by pressing and compressing.

In the above-mentioned coil brush, flanges are fitted into both ends of the cavity formed by the channel, and a roll insertion hole defined by the inner peripheral edge of the flange is formed at the center of each flange. A key groove is provided on the inner peripheral edge for engaging with the key of the roll, and the key is received in the key groove, and the roll is axially inserted into the roll insertion hole to transmit the rotation.

[0004]

The rotating roll brush is subjected to a polishing operation under a high-speed continuous operation, and is subjected to a strong impact on a regular basis, which may cause peeling at the winding end of the channel of each coil brush. have.

[0005] The present invention provides a coil brush for forming a rotary roll brush which appropriately solves the problem of channel separation by a flange.

Further, since the coil brush has a structure formed by spiral winding, the phenomenon that both side surfaces are inclined with respect to the axis cannot be forbidden. For this reason, the flange is internally fitted to the inner deep portion which is separated from the winding end of the channel. As a result, the winding end of the channel is separated from the flange, and it is difficult to reinforce the winding end by the flange to prevent the peeling.

[0007] The present invention provides a coil brush for forming a rotary roll brush in which the end of a channel can be appropriately reinforced by a flange.

The overhanging portion of the winding end of the channel, which causes the above-mentioned inclination, ie, the overhanging portion of the winding end of the coil brush, is crushed over a certain length to correct both sides of the coil brush so as to be as perpendicular to the axis as possible. A method of welding and reinforcing the channel end by fitting a flange at the end of the cavity is also conceivable, but this method significantly reduces the brush implant density of the channel end at a certain length due to the crushing process. Alternatively, an empty channel portion must be formed, and as a result, a region having a low brush density is formed in a region adjacent to each coil brush in the roll brush, causing a problem of uneven polishing. In addition, a complicated operation for giving a crushing process is required.

The present invention provides a coil brush for forming a rotary roll brush, which does not require crushing or the like at the winding end of the channel and which can effectively prevent the reduction of the density of brush installation.

Further, conventionally, a structure in which the coil brush is extrapolated to the roll while the key groove is engaged with the key, the channel winding ends in adjacent portions of the coil brush are separated from each other or overlap with each other. And a gap is generated on the surface of the rotary roll brush due to this, causing a problem of uneven polishing.

According to the present invention, the brush winding densities in the adjacent portions of the coil brushes are made uniform by abutting the end faces of the channels between the adjacent coil brushes in parallel, and the above-mentioned problems of the formation of gaps and the uneven polishing are properly solved. A coil brush for forming a rotary roll brush is provided.

SUMMARY OF THE INVENTION According to the present invention, flanges are fitted at both ends of a cavity formed by a channel of a coil brush, and a plurality of protruding pieces are spaced apart from the outer peripheral edge of the flange. Each of the projecting pieces was welded to the bottom of the channel, and one of the projecting pieces was welded to the bottom near the end face of the winding end of each channel to reinforce the winding end.
Preferably, one side edge of one of the projecting pieces coincides with the end face of the left and right winding ends of the channel.

The present invention appropriately solves the problem of peeling of the end of the channel by the above-mentioned inner fitting flange. The above-mentioned protruding pieces are separated from each other and independent of each other, so that one of them can be made longer than the other protruding pieces, that is, a length reaching the winding end of the channel projecting outward and welding to the bottom of the winding end. Can be achieved.

At this time, by aligning one side edge of one of the projecting pieces with the end face of the channel winding end, the end faces of the channel winding ends of the respective coil brushes extrapolated to the roll are brought into contact with each other, and The side edges of the pieces are butted against each other, and the flange bears a part of the butting strength.

Further, according to the present invention, one side edge of one of the projecting pieces is welded to the bottom of the channel so as to coincide with the end face of each winding end of the channel, and the other end face of each winding end of the channel is the same base of the coil brush. Place on a line. Then, one side edge of one of the protruding pieces is arranged on the center line of the key groove on the diameter line of the coil brush.

Due to the configuration in which the end faces of the channels are arranged on the same generatrix and the configuration of the flanges, one type of flange having the same protruding position of the protruding piece and the key groove forming position is provided at both ends of each coil brush. The end faces of the winding ends of the channels can be properly obtained only by engaging the key and the key groove.

By simply extrapolating the coil brush to the roll by the key groove and the guide of the key, the winding ends of the coil brushes in the rotary roll brush abut each other without gaps, and gaps and density unevenness are generated on the brush surface. Not a healthy rotating roll brush can be formed.

Further, a reinforcing piece is formed by bending one side edge of one of the protruding pieces onto the end face of the winding end of the channel.

This ensures the strength of the vicinity of the end of the channel and the end face thereof when the coil brushes of the rotary roll brush are brought into contact with each other, and effectively prevents peeling of the end of the channel brush.
