Abstract
Description
More particularly, the present invention relates to an interchangeable type grindstone assembly, which is capable of polishing a surface of an abrasive to be polished so that a cutting force can be improved by having a longer cutting edge and a longer cutting edge, The present invention relates to a replaceable grinding wheel assembly,
Generally, a grinding wheel is a kind of tool used to polish a metal or the like, and means a tool used to sharpen a blade of a knife or a work tool mainly in a home or a carpenter.
Particularly, a grindstone used for grinding a blade of a knife used in the home is traditionally the same as the example of Fig.
That is, when the worker uses a sense of his / her own knife on the surface of the
In addition, there is a problem that the surface of the
For example, a fixed type in which a grinding stone (abrasive) of a ceramic or stainless steel is superimposed on each other in a V shape, and then a blade such as a knife is passed through the abrasive stone to sharpen it is disclosed.
However, in this case, since the grinding stone is of a fixed type, only one of the grinding wheels is worn out, so that it is not possible to carry out subsequent polishing by the unevenly worn portion as in the example of Fig.
2, a cemented
In this case, it is very convenient because you can set the edge of the knife by pulling or pushing the knife blade against the 'V' groove. However, since the cutting edge is only changed, the cutting surface is not wide and the knife blade But also has a drawback that the cutting surface becomes rough.
In addition, although a plurality of grindstones such as those disclosed in Japanese Patent Application Laid-Open Nos. 2007-0099476, 1086984, and 1242043 are disclosed as related arts, the configuration is complicated in order to provide a convenient and efficient cutting surface. , And manufacturing costs are increased.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems in the prior art, and it is an object of the present invention to provide a polishing apparatus and a polishing apparatus which are structurally simple and easy to use while uniformly polishing a polished surface of a polished knife, The present invention provides a replaceable grinding wheel assembly which can reduce the cost by allowing only the grinding wheel to be detached when the grinding wheel is worn.
It is another object of the present invention to provide a replaceable grindstone assembly which can uniformly polish a knife or the like, sharpen a blade line, increase cutting force, and allow the cutting material to drop well.
According to another aspect of the present invention, there is provided a replaceable grindstone assembly including first and second grindstones (100, 200) for grinding a blade to rotate a blade, The first and
At this time, a plurality of embosses E are formed on the surfaces of the first and
The first and second fixing bases F1 and F2 are formed in the shape of a plastic bobbin having an inner diameter and the first and second keyways KH1 and KH2 are formed at corresponding positions of the inner diameter and the first and
In addition, the present invention provides a replaceable grindstone assembly including first and second grindstones (100, 200) for grinding a blade to grind the blade line; A pair of first and second holding frames (F1, F2) which are machined into a plastic bobbin in the shape of a truncated cone and are placed in contact with each other; The first and
In this case, the first and
In addition, the first and
According to the present invention, since the knife blade is erected using the warp-processed rotary type grindstone, the time required for grinding the blade is shortened, the polishing operation is easy, the polished surface is uniform and uniform and the quality is good, The cutting line can be polished for a long time, and the cutting force is improved, and the cutting material does not stick to the cutter after cutting, so that it is easy to use.
In addition, since the present invention allows only the grinding wheel to be detached and replaced when the grinding wheel is worn, the maintenance cost can be reduced.
1 and 2 are illustrations of a grinding wheel according to the prior art.
3 is an exemplary internal structural view of a replaceable grindstone assembly according to the present invention.
4 is an exemplary view showing another example of a replaceable grindstone assembly according to the present invention.
FIGS. 5 and 6 are views showing still another example of a replaceable grindstone assembly according to the present invention.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.
In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
As shown in FIG. 3, the replaceable grindstone assembly according to an embodiment of the present invention includes two grindstones, that is, a
At this time, the first and
In addition, the first and
The first and second

At this time, in the present invention, the length of the first and second
Particularly, since the first and second
On the other hand, the first and second fixing tables F1 and F2 are closely fixed to the rear end surfaces of the first and second grinding
The first and second fixing tables F1 and F2 are fixing members having the same diameter as the first and second
The first and second through holes H1 and H2 of the first and
At this time, if a plurality of embosses E and grooves (not numbered) for accommodating the embosses E are formed on the surfaces of the first and
The first and
The fixing structures of the first and second fixing tables F1 and F2 and the first and second
That is, as shown in FIG. 4 (a), the first and second fixing members F1 and F2 are formed into a plastic bobbin shape having an inner diameter, And the first and second keyways KH1 and KH2 are inserted into the first and second keyways KH1 and KH2.
In addition, the first and second fixing bases F1 and F2 of the plastic bobbin type may be formed into a truncated cone shape while the key coupling structure is maintained as described above, and then the first and
As another example, as shown in FIG. 4B, the first and
As is well known, the abrasive leather (100 ', 200') is very tough and soft and suitable for raising a knife-like blade. Here, the meaning of raising the knife blade is to grind the completely blunt blade It is a concept that the blades made of alloy such as stainless steel are thinner than the blades which are made of stainless steel, so that the parts are oxidized by contact with oxygen, and the blades are removed by removing fine oxide remaining on the surface.
Therefore, the example shown in Fig. 4 (b) can be used when the already polished blade is finely finished so as to have a fine and sharp blade.
In addition, although not shown, the first and
