Abstract

PURPOSE:To enable a rigid body to be cut off without feeding free abrasives as well as to efficiently use abrasives by continuously forming the long peripheral section of a metallic band shape plate into a saw teeth shape, and thereby forming a blade edge section on the surface of which diamond powder is attached by means of electrodeposition. CONSTITUTION:The cutting blade 10 is made up of a metallic band shaped plate 12, and of a blade edge section 14 continuously formed in a saw teeth shape over the long peripheral section of the band shaped plate 12. Diamond powder 15 is attached on the surface at the center section of the blade edge section 14 butting against a rigid body by means of electrodeposition. Each saw tooth is formed into a triangle shape. When the rigid body is cut off using the cutting blade 10, the rigid body is cut off by the diamond powder 15 electro- deposited on the blade edge section 14 of the cutting blade 10 by advancing/ retreating the cutting blade 10 with a cutting machine operated.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a cutting blade,
More specifically, the present invention relates to a cutting blade used when cutting a rigid body such as stone, silicon, ceramic, or glass.

[0002]

2. Description of the Related Art A conventional cutting blade is formed by using a metal strip plate, and a long edge portion that abuts a rigid body such as stone, silicon, ceramic, or glass is formed in a straight line, and its surface is formed. No cutting material is attached. Therefore, when cutting a rigid body using this cutting blade, during cutting work, loose abrasive grains mixed with a cutting material in a liquid such as oil are repeatedly moved forward and backward while being pressed in the rigid body direction. The contact surface between the blade and the rigid body is continuously supplied from the outside. As a result, the cutting material that has entered between the contact surface of the cutting blade with the rigid body and the surface to be cut of the rigid body moves on the surface of the rigid body to be cut under the pressure from the cutting blade. The surface of will be cut.

[0003]

However, the above-mentioned conventional cutting blade has the following problems. The cutting material that actually enters between the contact surface of the rigid body of the cutting blade and the surface to be cut of the rigid body, and cuts the rigid body is a part of the cutting material contained in the supplied loose abrasive grains, Most of the cutting materials are not used for cutting and are discarded, so the usage efficiency of the cutting materials is low. Therefore, a large amount of free abrasive grains, that is, a cutting material, is required for the cutting work of the rigid body. Therefore, when cutting a rigid body in a short time to improve the efficiency of cutting work, it is better to use diamond fine powder as the cutting material, but considering the production cost, diamond fine powder, which is expensive, is used. Cannot be achieved and productivity cannot be improved. Further, since the cutting blade itself is cut by the cutting material at the same time as cutting the rigid body, there is a problem that the cutting blade can be used only once. Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a cutting blade capable of cutting a rigid body without using loose abrasive grains.

[0004]

The present invention has the following constitution in order to achieve the above object. That is, the present invention is characterized in that a long edge portion of a metal strip plate is continuously formed in a saw-tooth shape, and a cutting edge portion on which the fine diamond powder is electrodeposited is formed.

[0005]

The blade for cutting is continuously formed in a saw-tooth shape on the long edge portion of the metal strip plate, and the blade edge portion on which the fine diamond powder is electrodeposited is formed on the long edge portion. Rigid bodies can be cut without supplying grains.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. 1A and 1B are views showing a first embodiment of a cutting blade according to the present invention, in which FIG. 1A is a front view and FIG. 1B is a side view. FIG. 2 is an enlarged view of the cutting edge portion of FIG. FIG. 3 is an enlarged view of the cutting edge portion of the second embodiment. FIG. 4 is an enlarged view of the cutting edge portion of the third embodiment. First, the configuration of the first embodiment will be described with reference to FIGS. The cutting blade 10 includes a metal strip 12
And a blade edge portion 14 continuously formed in a sawtooth shape on the long edge portion of the strip plate 12. Further, diamond fine powder 15 is electrodeposited on the surface of the central portion of the cutting edge portion 14 that abuts on a rigid body (not shown). The sawteeth 16 are formed in a triangular shape.

The electrodeposition of the fine diamond powder 15 on the cutting edge portion 14 will be described in more detail. First, the long edge of the strip 12 is formed in a sawtooth shape by a grinding machine, and then the long edge of the strip 12 is formed. Except for the central part, masking is done with tape. After this, as procedure 1, first, the strip plate 12 is dipped in an electrolytic solution of nickel, and the central portion of the long edge portion is plated with a single layer of nickel. Next, as a procedure 2, the diamond fine powder 15 is dipped in an electrolytic solution of nickel,
A second layer of nickel plating is applied. Thereby, the strip 1
The fine diamond powder 15 is electrodeposited on the central portion of the long edge portion of 2. Further, as step 3, the strip plate 12 is again dipped in the nickel electrolytic solution, and the central portion of the long edge portion is plated with the third layer of nickel. This plating protects the diamond fine powder 15 contained in the second layer plating. Through the above procedure, the cutting blade 10 in which the fine diamond powder 15 is electrodeposited on the cutting edge portion 14 is completed. Note that the diamond fine powder 15 may be formed in any number of layers by repeating the above procedure 2 and procedure 3.

Next, a case of cutting a rigid body (not shown) using this cutting blade 10 will be described.
The cutting blade 10 is attached to a cutting machine (not shown) so that the cutting edge portion 14 of the cutting blade 10 contacts a rigid body. After this, the cutting machine is operated to move the cutting blade 10 back and forth. As a result, the diamond fine powder 15 electrodeposited on the cutting edge portion 14 of the cutting blade 10 contacts the surface of the rigid body, and the rigid body is cut. Further, since the cutting edge portion 14 has a saw-toothed shape, it is possible to release the cut chips of the rigid body and prevent the cutting ability of the cutting blade 10 from decreasing.

Further, as in the second embodiment shown in FIG. 3, the saw teeth 16 of the cutting edge portion 14 may be formed in a rectangular shape.
Further, when the saw teeth 16 of the cutting edge portion 14 are formed in a corrugated shape as in the third embodiment shown in FIG. 4, there is no portion where stress concentrates on the cutting edge portion 14 and cracks are less likely to occur. Therefore, the durability of the strip plate 12 is improved. As described above, the diamond fine powder is electrodeposited by plating on the cutting edge of the cutting blade, and the diamond fine powder is in contact with the rigid body for cutting, so that the strip plate is directly rigid until the plating comes off. Since the strips do not abut, the strip itself does not wear, and therefore the cutting blade can be used repeatedly until the plating comes off.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.

[0011]

EFFECTS OF THE INVENTION When the cutting blade according to the present invention is used, the cutting blade is continuously formed in a sawtooth shape on the long edge portion of a metal strip plate, and the surface thereof has a diamond fine powder electrodeposited on it. Since the portion is formed, the rigid body can be cut without supplying loose abrasive grains from the outside. Therefore, since the abrasive grains can be used efficiently, the cost increase can be prevented even if expensive diamond fine powder is used, and the cutting time can be shortened by using the diamond fine powder. It works.
