Electrically driven board cutter blade

Abstract

To provide a strong and long-lasting electrically driven board cutter blade whose initial performance can be maintained for a long time, because conventional electrically driven board cutter blades have a comparatively short life.MEANS FOR SOLVING THE PROBLEM: Cutting blades are provided to an entire circumference of a blade body in an electrically driven board cutter, and the blades are possible to be replaced in an opposite direction and used. Products each capable of maintaining high performance for a long time are realized by making each angle of the cutting blades be an efficient angle.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a tool used for cutting gypsum boards and wood boards. [Background technology]

[0002] Although there are electric board cutter blades manufactured and sold by a number of manufacturers, it is desired to realize an electric board cutter blade that is superior in performance and durability to these. [Prior art documents] Summary of the Invention [Problem to be solved by the invention]

[0003] The challenge of how to extend the life of an electric board cutter blade lies in changing the blade structure. [Means for solving the problem]

[0004] To achieve the above object, the present invention provides a saw-tooth cutting blade (2) around the periphery of a steel plate (1) having a thickness of 0.7 mm to 0.9 mm, a length of 55 mm to 57 mm, and a width of 15 mm to 17 mm, with a mounting groove (3) in the center having a length of 43 mm to 45 mm and a width of 4.0 mm to 4.5 mm. The height (6) of the cutting blade is 1.5 mm to 2.0 mm, the width (7) of the base of the cutting blade is 2.0 mm to 2.5 mm, the interior angle (4) of the cutting edge of the cutting blade is 25° to 35°, and the inclination angle (5) of the cutting blade relative to the extension line (8) of the base of the cutting blade is 50° to 70°, thereby realizing an electric board cutter blade that maintains high performance and has a long life. [Effects of the Invention]

[0005] As described above, the blade of the electric board cutter of the present invention exhibits high performance in cutting gypsum boards and wooden boards, and at the same time, it is easy to use and economical because of its long life. [Brief explanation of the drawings]

[0006] [Figure 1] 1 is a front view of a blade of an electric board cutter showing an embodiment of the present invention. [Figure 2] FIG. Modes for carrying out the invention

[0007] The blade of the electric board cutter of the present invention has cutting edges all around, but when cutting a material, the cutting edge in the cutting direction is mainly used, and the cutting edge on the opposite side acts as a deburring blade. If the blade's performance deteriorates after use for cutting, it can be replaced with the blade on the opposite side that was used as a deburring blade, allowing the blade to perform as well as it did originally. The cutting ability of the blade decreases with use, but to compensate for this, sharpening it can be done in the same way as a regular saw to restore its performance. The blade of this electric board cutter is compatible with both plasterboard and woodworking. [Explanation of symbols]

Claims

[Claim 1] A saw-like cutting blade (2) is provided around the periphery of a steel plate (1) having a thickness of 0.7 mm to 0.9 mm, a length of 55 mm to 57 mm, and a width of 15 mm to 17 mm, and a cutting edge (3) having a length of 43 mm to 45 mm and a width of 4.0 mm is provided in the center. The blade of the electric board cutter has a cutting blade height (6) of 1.5 mm to 2.0 mm, a cutting blade base width (7) of 2.0 mm to 2.5 mm, an inner angle (4) of the cutting blade tip of 25° to 35°, and an inclination angle (5) of the cutting blade relative to an extension line (8) of the cutting blade base of 50° to 70°.
