JP2005145033A - Thickness-thinning grind and dual blade saw toothed without set of tooth - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a dual blade saw toothed without set of teeth in which both blades have stabilized thickness and their cutting effect or cutting force is enhanced by mechanizing the surface grinding of a saw body such that the front side near the neck part of the saw body has an original thickness but the body is gradually thinned toward its distal part to become a thin blade in its distal end. <P>SOLUTION: The thickness-thinning surface grinding work 7 of the body 2 of the dual blade saw 1 is mechanically performed so that the front side 3 near the neck part has the original thickness and the body is gradually thinned toward its distal part to become the thin blade in the periphery 5 of its distal end. Then, the cross-cutting blades 8 are set on one side of the longitudinal direction of the body, and the longitudinally cutting blades 9 on the other side while stabilizing the thickness of both blades, and finally they are toothed 10 without set of teeth. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

    The present invention relates to a double-edged saw with plate thickness slide polishing and sharpening.

    Conventionally, as an effect of suppressing run-out during cutting of a double-edged saw, the thickness of the front of the neck is polished by thinning the surface of the saw blade so that the thickness near the front of the neck is thinned, and the tip of the saw blade is thin. However, there was a problem that advanced polishing work was required, and it could only be done by manual polishing.

    In the present invention, in order to enhance the cutting effect of the double-edged saw, the thickness near the front of the neck is polished by polishing the surface of the saw blade so that the thickness of the blade is gradually thinned forward and the tip of the saw blade becomes a thin blade. The purpose of the present invention is to provide a double-edged saw with sharpening without claws with a blade thickness that is mechanized and a blade thickness slide polished by mechanization and with a constant blade thickness for both blades and an increased cutting force.

    In order to achieve the above-mentioned problem, in the saw blade of a double-edged saw, both the surfaces in the longitudinal direction are in the state of the thickness to be used at the front of the rear neck, and the thickness of the blade is gradually thinned toward the front. Thick edge slide polishing is performed by mechanization with a thin blade around the tip, and a horizontal grinding blade is provided on one side, which is the longitudinal direction of the saw blade, and a vertical grinding blade is provided on the other side. Take a means to make it constant and sharpen without claws.

    In addition, by machining the plate thickness slide polishing process, it is possible to polish evenly and accurately on the surface of the saw blade, the blade is bent with good deflection and less blade shake, and the blade is sharp when cutting with sharpening. It is preferable to eliminate the resistance and to remove wood chips at the same time to improve the cutting speed and provide a beautiful cut surface.

    The double-edged saw that has been subjected to plate thickness slide polishing and sharpening without claws of the present invention is designed to increase the effect of absorbing and cutting vibration due to back-and-forth operation during cutting. The surface of the saw blade, which is gradually thinned toward the tip and is thinned around the tip of the saw blade, is used for both the blade thickness slide polishing process and the two blades, which have so far required high technology and could not be mechanically polished. This is a sharpening process without claws with a constant blade thickness and increased cutting force.

    In the embodiment shown in FIG. 1, in the blade 2 of the double-edged saw 1, on both surfaces in the longitudinal direction, the rear neck portion 3 near the front of the neck is used as the thickness 4 to be used, and the plate thickness is gradually reduced toward the front. The thickness of the saw blade tip 5 is reduced to a thin blade state 6 by a mechanical thickness polishing 7, and the saw blade 2 has a horizontal grinding blade 8 on one side and a vertical grinding blade on the other side. No. 9 is provided, and the blade thickness is constant for both the blades, and the sharpening process 10 is not performed.

    In addition, by performing the plate thickness slide polishing process 7 by mechanical polishing, the surface of the saw blade 2 can be evenly and accurately polished, the saw blade 2 is bent flexibly with little blade shake, and there is no settling. The sharpening process 10 eliminates the resistance of the saw blade during cutting, and at the same time eliminates wood chips so that the cutting speed is improved and a beautiful cut surface is obtained.

    It is a side view which shows the Example of this invention.
