Abstract

PURPOSE:To prevent the fall of the abrasive material, and reduce the frequency of application of the abrasive material and the consumption thereof by overlapping multiple buff clothes having multiple projecting parts and recessed parts on the surface thereof to form a wheel-shape, and housing the abrasive material in the recessed parts, and holding it with the projecting parts between each buff cloth. CONSTITUTION:A circular buff cloth 1 is formed with multiple projections 2 and multiple recessed grooves 3, which are positioned between the projections 2, so as to be parallel to each other, and a hole 4 is formed in the center of the buff cloth 1. Multiple circular buff cloths 1 are overlapped concentrically, dislocating the direction of the projections 2 in order, and the peripheral parts of the holes 4 are sewn with each other by a thread 5 to form a disc-shape buff wheel. Furthermore, each disc-shape support plate 6 having a shaft through hole 7 is adhered to both side surfaces of the hole 4 of the disc-shape buff wheel to form a buff polishing wheel W. Plural buff polishing wheels W are supported concentrically and freely to turn, and the peripheral surface thereof is coated with the abrasive material 9. At this stage, the abrasive material 9 is housed in the recessed grooves 3 and held by the projections 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buffing wheel formed by polymerizing a large number of buff cloths into a ring shape.

[0002]

2. Description of the Related Art Generally, a buffing wheel is generally used by applying an abrasive to the outer peripheral surface of the wheel during polishing. In that case, the applied abrasive is held on a buff cloth for a long-term sharpness. Is desired to be maintained.

Therefore, conventionally, when a plurality of circularly cut buff cloths are polymerized, spacer cloths having a smaller diameter than the buff cloths are sandwiched between the buff cloths, and the buff cloths are superposed by the spacer cloths. It is widely used that the applied abrasive is contained in a gap formed between the two.

[0004]

However, in this conventional buffing wheel, there is nothing to hold an abrasive in the gap formed between the buff cloths, and the buffing wheel is entirely open to the outer peripheral surface of the polishing wheel. Therefore, even if the abrasive is once stored in the gap, the abrasive is easily removed from the gap at the time of high-speed rotation and only slightly remains in the texture of the buff cloth. Therefore, in the polishing work, the abrasive is frequently used. However, there is a drawback in that it is inconvenient for the work and the economical disadvantage that the abrasive must be applied. The present invention aims to eliminate the drawbacks of the prior art.

[0005]

Means for Solving the Problems As a means for solving the above problems, according to the present invention, a plurality of buff cloths having a large number of irregularities on a cloth surface are polymerized to form a ring shape, and the buff cloths are overlapped with each other. A buffing wheel is characterized in that a large number of concave portions of each uneven surface are formed in the abrasive material storage gap and a large number of convex portions are formed in the abrasive material holder.

The above "concavities and convexities" in the present invention include linear ones such as straight lines and curved lines, points and spots, and various other forms.

The above-mentioned "unevenness" is formed by applying glue to a buff cloth and heating and pressing with a desired mold,
As the paste, starch paste, casein paste, poval paste, etc. are used, and polyethylene etc. are used as resin-processed paste. What is formed and various other irregularities are included.

Further, in the present invention, "the buff cloths are polymerized into a ring shape" means that a large number of buff cloths cut in a circular shape are concentrically overlapped with each other to form a disk shape, a drum shape, or the like. Formed in a circle, or a large number of buff cloths cut in a fan shape are arranged in a circle while partially overlapping the petals in order, and formed into a ring shape such as a disk shape or a drum shape by overlapping one or more turns. , A long strip of buff cloth is folded in order to form a circular shape while partially folding it.
It includes a ring-shaped body such as a disk-shaped body or a drum-shaped body formed by stacking a plurality of layers around each other, and other various buff cloth polymerized ring-shaped bodies. Embodiments of the present invention will be described below with reference to the drawings.

Example 1 A buff cloth (1) shown in FIG. 1 (a) is composed of a straight-woven cotton cloth having a starch content and a number of linear projections (2) ... (2)
It is a circular buff cloth having a hole (4) at the center formed by forming concave grooves (3) in parallel with each other (2). The convex stripes (2) ... and the concave grooves (3) ... form a concave groove and a convex stripe on the back surface, respectively.

A large number of the buff cloths (1) (2 as an example)
0 sheets) are concentrically overlapped with each other while sequentially shifting the directions of the convex stripes (2) ... In this case, the holes (4) of the buff cloth (1) ... , A disc-shaped buff wheel is formed by stitching with a thread (5), and a disc-shaped support plate (6) having shaft through holes (7) on both sides of the buff wheel holes (4). (6) is adhered with an adhesive to form a buffing wheel (W).

In use, the buffing wheel (W) described above is used.
... A plurality of shafts are fitted to one shaft through the support plates (6) (6), the shaft through holes (7) (7), ... of the buffing wheels (W) ... side by side. Tighten in a state of pressing. The outer peripheral surface (polishing surface) of such a buffing wheel (W) ...
The polishing material (9) is applied to the ... And rotated, and the object to be polished is brought into contact with the polishing surface to perform polishing. The above-mentioned applied abrasive (9) is pushed between each polymerization adjacent buff cloth (1) (1), ... And each buff cloth (1) ... as shown in FIG.
The outer surface (8) of the buff cloth (1) is prevented from falling off to the wa by the ridges (2) and the outer peripheral surface (8) of the buff cloth (1). On the back surface of the back surface, the abrasive material (9) is housed in the groove of the back surface of each of the convex stripes (2), and is removed by the projection of the back surface of the concave groove (3). Therefore, the abrasive material (9) is housed and held in the concave grooves by the ridges when the polishing wheel (W) rotates at a high speed.

[0015]

According to the buffing wheel of the present invention, the abrasive material applied to the outer peripheral surface (polishing surface) of the polishing wheel during use is accommodated in a large number of recesses between each adjacent buff cloth. It is held by the convex part, which makes it possible to sufficiently prevent the abrasive from falling off during rotation polishing, or to keep it small, so that the number of times of applying the abrasive is reduced and the waste of the abrasive is significantly increased as compared with the conventional wheel. It can be reduced.
