In this case, poly crystalline diamond (3) is generally referred to as 'PCD', which is mixed with metal powder and pressurized and sintered to 1000 atm below 1000 ° C. It is mainly used for rotary blades.

However, in the conventional wheel 2, in order to use the expensive PCD 3, it is attached with the minimum number, without arranging a large number.

In other words, the wheel 2 is in a state where only the minimum number is arranged to obtain the maximum grinding effect on the contacted surface.

However, this high strength PCD (3) was very weak to brittleness, if some of the failure to sharply or even if the ability to remove, even if the situation was used to replace the entire wheel.

The present invention has been developed to solve the above problems, the object of the present invention is to develop a wheel that uses a PCD that is machined to a certain shape, or a PCD of a relatively small particles without processing.

It is also to provide a wheel that does not sharply drop efficiency even if some PCD is broken.

It also provides a wheel that can replace a partially damaged PCD.

In order to achieve the above object, the present invention has a convex plate-shaped upper surface, and a fixing hole is fixed to the center of the upper surface to be coupled to the power tool, and the bottom surface is partially embedded to remove the polycrystalline diamond (PCD). In the wheel of the tool;

A plurality of protrusions protruding in a cylindrical shape with a predetermined height adjacent to the bottom edge of the wheel is integrally formed, and the bottom surface of each of the protrusions is embedded to expose a plurality of polycrystalline diamond pieces.

In addition, the protrusion is characterized in that the shape of the square pillar.

In addition, the protrusion is characterized in that the triangular prism shape.

In addition, an insertion groove into which the protrusion is inserted is formed at a portion where the protrusion of the wheel is mounted, and a coupling hole is formed at the center of the insertion groove;

The protrusion is manufactured separately so that a screw hole corresponding to the coupling hole is formed on an upper surface thereof;

When the protrusion is coupled to the insertion groove is characterized in that it is fixed by the coupling bolt.

In addition, the top of the protrusion is manufactured separately and joined to the protrusion by welding, characterized in that the pad is provided with the screw hole and has a shape that is correspondingly inserted into the insertion groove.

As described above, the present invention has the effect of reducing the cost of the wheel by manufacturing the wheel using a fragmented PCD or a PCD having a relatively low cost small particles.

In addition, by using a large number of pieces of PCD, even if some damage, the efficiency of the device does not significantly reduce the durability is excellent effect.

In addition, it is possible to replace parts that are partially damaged and the role is significantly reduced, thereby reducing the cost of repurchase and can use the wheel semi-permanently.

Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

Figure 1 is a bottom perspective view according to an embodiment of the present invention, Figure 2 is a side cross-sectional view according to an embodiment of the present invention, the upper surface has a convex plate-shaped fixed in the center of the upper surface coupled with the power tool (1) In the wheel of the elastic film removal tool is formed, the hole 21 is formed, the bottom surface is embedded so that the polycrystalline diamond (PCD; 3) is partially exposed;

A plurality of protrusions 4 protruding in a cylindrical shape with a predetermined height adjacent to the bottom edge of the wheel 2 are integrally formed, and a plurality of polycrystalline diamond pieces 31 are partially exposed on the bottom of each of the protrusions 4. The wheel used for the elastic film removal tool, characterized in that it is embedded.

The biggest advantage of the present invention is that the unit price is very low because it uses the PCD piece 31 is not processed without using the processed PCD.

In particular, if the damage occurs such as cracking during the conventional PCD processing, the value of the product is often lost, it is a great advantage to use this.

In addition, the process of forming the protrusions 4 may be integrally formed. However, the process of forming the PCD piece 31 on the upper surface in the process of pressing and molding the metal powder only on the protrusion part may be performed by welding. The most preferred embodiment.

3 is a bottom perspective view showing an example of a protrusion having a different shape in the present invention, the protrusion 4 may be manufactured in various shapes such as a triangular prism or a square pillar.

The formation of the protrusions 4 is due to the nature of the present invention using a small crystal PCD piece 31 so that if the bottom of the wheel 2 is buried directly on the bottom of the wheel 2, the bottom surface of the wheel 2 is in contact with the floor and worn or the cause thereof. This is to prevent the PCD fragment 31 is damaged or falling occurs.

In this case, the contact area with the floor is small, which minimizes the resistance during operation, thereby enabling effective work.

4 is a bottom perspective view according to another embodiment of the present invention, Figure 5 is a side cross-sectional view according to another embodiment of the present invention, the protrusion 4 is provided in the portion where the protrusion 4 of the wheel 2 is mounted An insertion groove 22 to be inserted is formed so that a coupling hole 23 is formed in the center of the insertion groove 22;

The protruding portion 4 is manufactured separately so that a screw hole 41 corresponding to the coupling hole 23 is formed on an upper surface thereof;

When the protrusion 4 is coupled to the insertion groove 22 is shown an embodiment to be fixed by the coupling bolt (5).

This embodiment allows only the protrusion 4 including the PCD piece 31 to be replaced when partial damage occurs.

6 is a side cross-sectional view according to another embodiment of the present invention, which is separately manufactured at the upper end of the protrusion 4 and is joined to the protrusion 4 by welding, and includes the screw hole 61 and the insertion groove. An embodiment in which the pad 6 having a shape corresponding to that of (22) is additionally configured is shown.

This is mainly caused by the above-described metal powder molding.

That is, in the case of metals having high melting point such as cobalt, titanium, and tungsten and having high melting point, they are molded by powder metallurgy or sintering.

In the case of mounting a PCD having a high strength, general carbon steel is unsuitable, and a metal material having a high strength is used, and a suitable metal is generally manufactured by a sintering process.

However, the screw hole forming operation is very difficult for the parts manufactured by the sintering work, and there are many problems of damage to the parts.

For this reason, the pad 6, which is easy to process the screw hole 61, is welded and the screw hole 61 is formed in the pad.

In the case of the above method, the protrusion 4 manufactured by sintering or a metal powder generally referred to as a part manufactured by sintering in the industry may be easily heat treated to increase durability.
