Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To provide a cutting blade for woodworking, which enables a desired work to be easily and speedily performed by a person who is not a skilled worker in the process, and has high safety and excellent work feeling. .. SOLUTION: Bending cutting blades each having a substantially L-shaped cross section are provided at a peripheral edge of a disk-shaped blade main body at a predetermined pitch so as to sequentially change their bending directionality, and each cutting blade has a deep depth. It is assumed that the control claw body is provided adjacently.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a cutting blade for woodworking, and more particularly to a cutting blade for woodworking used for producing wood products having relatively individual characteristics such as carvings, folk craft products, and floor pillars.

[0002]

[Background of device]

 In general, most of the above-mentioned work requires manual tools and tools, which requires a lot of time from roughing to surface finishing, and sometimes requires skill. Has become.

[0003]

[The purpose of the device]

 Therefore, the present invention has been made by paying attention to the actual situation and problems of the related art. By solving these problems, even a person skilled in the process can easily and speedily perform desired work. The purpose of the present invention is to provide a cutting blade for woodworking, which is highly safe and has a good work feeling.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, the cutting blade for woodworking according to the present invention has a curved cutting blade portion having a substantially L-shaped cross section at a predetermined pitch on the periphery of a disk-shaped blade body in the bending direction. The cutting blades are characterized in that they are provided so as to project, and each cutting edge portion is provided with a claw body for depth control adjacently.

[0005]

[Action]

 With the above configuration, when the peripheral edge of the rotating blade body comes into contact with the target wood to be cut, the cutting blades change the bending direction alternately, so the friction resistance is small and the work can be done with a light touch. Moreover, the depth is controlled by the presence of the claws, and irreversible mistakes can be prevented.

[0006]

[Embodiment of device]

 Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a cutting blade for woodworking according to the present invention, Fig. 2 is a front view showing the same proper use condition, Fig. 3 is a perspective view showing the rough cutting work condition, and Fig. 4 is the finishing work condition. FIG. 5 is a perspective view of a glider to which a cutting blade is to be attached.

In these drawings, reference numeral 1 denotes a steel blade main body, and the blade main body is provided with a mounting hole 3 at the center thereof for mounting on a motor shaft of a disc grinder 2 shown in FIG. Further, the blade body 1 has a disk shape, and the peripheral edge 4 is protruded in a stepped shape in a flat plate shape.

Further, cutting blade bodies 5, 5, ... B bent in a substantially L-shaped cross section are formed on the peripheral edge 4 of the above-mentioned blade body 1 at a pitch of 60 degrees. It has been changed in the opposite direction.

Further, the claw bodies 6, 6 ... Are provided so as to be adjacent to the respective cutting blade bodies 5, 5, ... And these claw bodies 6, 6 ... Are arranged in the rotational direction of the blade body. It is located in front of the cutting blades 5, 5, ... And forms a gentle arc line in the direction of rotation. That is, the claw bodies 6, 6 ... Control the cutting depth and guide the cutting of the cutting blade bodies 5, 5 ,.

The cutting blade for woodworking according to the present embodiment is configured as described above, and the blade body 1 is attached to the disc grinder 2 as described above. As a state of use, the blade body 1 is brought into contact with the object A to be cut with the cover 2a of the grinder 2 set at about 45 degrees. At this time, the orthodox holds the grip 2b of the grinder 2 with the left hand and, if possible, the optional auxiliary grip 2c with the right hand to establish a firm and stable state.

Further, the blade main body 1 becomes groove cutting when it goes straight in the rotating direction, and becomes cutting by moving it in a direction intersecting with the rotating direction. By defeating like this, it becomes a sharpening with an emphasis on finishing.

[0012]

[Effect of device]

 The cutting blade for woodworking according to the present invention is constructed and operates as described above. Therefore, anyone can easily and quickly perform work on various types of wood to be cut, the work accuracy is high, and the safety is high. In addition, since the cutting blade can be used by polishing, it has a long product life and is economically advantageous.
