Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cutting apparatus for cutting a hard material,

Disclosed is a cutting apparatus for machining a hard and high-hardness cutting-resistant material.

In the case of a cutter for cutting incombustible materials such as inconel, titanium, and high manganese steel, a phenomenon that the carbide tip of the cutter (insert tip) is damaged by high hardness of the material frequently occurs.

In order to compensate for this, the carbide tool maker controls the fracture phenomenon of the carbide due to the increase of the toughness of the carbide itself or the change of the cutting toughness by controlling the amount of cobalt of carbide.

However, there is still a lack of an optimal solution for high-hardness, high-strength material cutting.

In addition, in the case of the carbide tip, if one side is worn, if it is machined by turning it to another side, it can be used again four times or more, but if it is damaged, it needs to be replaced with a new carbide tip immediately.

The present invention provides a cutting device for machining hard materials, which can prevent breakage of a carbide tip due to impact relaxation by assembling a carbide tip through a locator when machining a hard material.

A cutting device for machining a hard material includes a tool wheel which is formed in a disk shape and processes a hard material through its rotation; A locator having an assembly part formed along the rim of the tool wheel and assembled in a state where a side surface and a rear surface are in contact with each other, And a cemented carbide tip that is detachably attached to the assembling portion of the locator so as to be able to be detached from the locator and directly cuts the rough material by contact with the roughing material.

The locator may be a structure made of high-carbon steel for structure that absorbs the impact of the carbide tip.

The locator is formed with a lining of brass material on one side and the rear side which are in contact with the tool wheel.

The brass material lining of the locator may be structured such that an oblique surface is formed and closely attached to the assembly space of the tool wheel.

The oblique surface may have a concavo-convex shape by intersection of a continuous concave portion and a concave portion.

According to this apparatus, a locator for supporting a carbide tip can be provided on a tool wheel to prevent breakage of a carbide tip when machining a hard-to-reach tough material.

In addition, by effectively absorbing the impact applied to the carbide tip using the locator, the life of the carbide tip can be extended more than twice as compared with the conventional one, and the economical effect can be achieved by extending the service life of the carbide tip.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms as used herein include plural forms as long as the phrases do not expressly express the opposite meaning thereto. Means that a particular feature, region, integer, step, operation, element and / or component is specified, and that other specific features, regions, integers, steps, operations, elements, components, and / And the like.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

1 is a view schematically showing a cutting apparatus for machining a hard material according to the present embodiment.

As shown in Fig. 1, the cutting device for machining a hard material can prevent damage to the insert tip when machining the hard material having a high hardness and high toughness.

In this embodiment, the cutting device for machining a difficult-to-cut material is roughly composed of a tool wheel 10, a locator 20 and a carbide tip 30. In a state where the carbide tip 30 is installed on the locator 20, .

In other words, the tool wheel 10 is formed in a disc shape, and is used for machining a rough material through its rotation. The locator 20 is provided with an assembly space formed along the rim of the tool wheel 10, And the cemented carbide tip 30 is detachably attached to the assembly part 21 of the locator 20 so that the cemented carbide tip 30 can be directly brought into contact with the material It is possible to cut a hard material.

The cutting device for machining a hard material is characterized in that the carbide tip 30 is mounted on the tool wheel 10 via the locator 20 so that the locator 20 can be moved in a direction perpendicular to the axis of the carbide tip 30 And a high-carbon steel structure for absorbing the high-carbon steel.

Since the locator 20 can effectively absorb the impact applied to the carbide tip 30, it is possible to prevent the carbide tip 30 from being broken during processing of the material for roughing.

2 is a view schematically showing the locator of the cutting apparatus according to the present embodiment.

FIG. 3 is a view schematically showing a lateral side engaging portion of the locator according to the present embodiment.

4 is a view schematically showing a rear-side engagement portion of the locator according to the present embodiment.

5 is a view schematically showing an oblique surface formed in a joint portion of the locator according to the present embodiment.

2 to 5, the locator 20 is formed with a lining 22 made of brass on one side and a rear side contacting the tool wheel 10, and the brass of the locator 20 The material lining 22 may have a structure in which an oblique surface 23 is formed and closely assembled to the assembly space of the tool wheel 10.

A lining 22 of brass material is formed on the assembly surface of the locator 20 and the lining 22 forms an oblique surface 23 so that the contact between the locator 20 and the tool wheel 10 And the lining 22 is made of a brass material in order to strengthen the fixing force of the locator 20. [

The beveled surface 23 has a concavo-convex shape by intersection of the continuous concave portion 23a and the concave portion 23b. The beveled surface 23 has a concavo- The locator 20 can absorb more effectively.

For example, the tool wheel 10 supporting the cemented carbide tip 30 constitutes a cutting device, and the tool wheel 10 is a cutting tool, The carbide tip 30 is attached to the tool wheel 10 via the locator 20 so that the carbide tip 30 is inserted through the structure of the locator 20, Can be absorbed.

It is preferable that the locator 20 is made of a structural high carbon steel having excellent impact absorption and restoring force. The locator 20 itself is made of a high carbon steel material and has excellent elasticity, so that the shock absorbing and restoring force can be improved.

The locator 20 has a brass material lining 22 for enhancing the fixing force of two contact surfaces with the tool wheel 10 and a groove 23 in the shape of a surface 23 of the lining 22, The adhesion between the tool wheel 10 and the locator 20 can be increased.

The beveled surface 23 forms a concave / convex portion through intersection of the continuous concave portion 23a and the concave portion 23b, so that the concavo-convex portion serves as a projection and a shock absorbing function, so that the carbide tip life is twice as long as that of the conventional cutter .

Therefore, the locator 20 for supporting the carbide tip 30 can be provided on the tool wheel 10 of the cutting device for machining a difficult material, so that the carbide tip 30 can be prevented from being damaged during the machining of the hardly- The lifetime of the cemented carbide tip 30 can be extended more than twice as compared with the conventional one by effectively absorbing the impact applied to the carbide tip 30 by using the locator 20, So that an economical effect can be achieved.

While the illustrative embodiments of the present invention have been shown and described, various modifications and alternative embodiments may be made by those skilled in the art. Such variations and other embodiments will be considered and included in the appended claims, all without departing from the true spirit and scope of the invention.
