Blade saw for cutting and manufacturing method thereof

Abstract

The invention provides a blade saw for cutting and a manufacturing method thereof, wherein the flexure stress of a matrix metal disk is fully increased while small stones and the like can be prevented from springing upward, the safety performance is excellent; and the blade can be inserted in the weed tree and the like in a right angle manner for cutting, and good cutting performance can be obtained easily. The matrix metal disk is characterized in that the matrix metal disk is provided with an installation flat section and a stair-shaped part and a blade flat section, wherein a mounting holethrough which the blade saw is installed on a cutting machine, is formed on the central part of the installation flat section; the stair-shaped part is arranged on the outside of the installation flat section and protrudes to the opposite side of the cutting machine; the blade flat section is arranged on the outside of the stair-shaped part, faces to the peripheral direction of the matrix metal disk and extends nearly parallel to the installation flat section; when the installation flat section is installed on the cutting machine through a mounting bolt, the stair-shaped part is higher than the protruding part of the mounting bolt; and a plurality of protruding sections which are in a concentric state with the mounting hole are formed on the blade flat section, and the protruding sectionsprotrude to the opposite side of the cutting machine and are roughly hemispherical.

Description

technical field [0001] The present invention relates to a cutting blade saw mounted on a cutting machine and used for cutting weeds or miscellaneous wood (hereinafter referred to as miscellaneous wood, etc.) and a manufacturing method thereof. Background technique [0002] Conventionally, as a blade saw for cutting, for example, Figure 8 And the blade saw shown in Fig. 9 is well known. Such as Figure 8 As shown, in this blade saw 101, a mounting hole 103 for mounting to a cutting machine 104 is formed on a flat portion 102a of the central portion of a disc-shaped base metal disk 102, and at the same time, a downward expansion is formed around the outer side of the flat portion 102a. The ring-shaped bulging portion 102b. In addition, on the outside of the bulging portion 102b of the base metal disk 102, the blade portion 102c faces the direction of the flat portion 102a and is tilted backward. [0003] Then, as shown in Fig. 9 (a), (b), on the blade mounting portion 105 a...

AI Technical Summary

Problems solved by technology

[0007] In addition, when cutting miscellaneous wood, etc., the operator will strive to cut off the roots of miscellaneous wood, etc., so that the blades 106, 107 as blades will easily enter the bottom of small stones, etc., causing the small stones to bounce upwards. Or the damage to the blades 106, 107 causes fragments to fly, so that personal accidents may occur to the operator
