Description

Double-edge cutter

Technical Field

The utility model relates to the technical field of machining, in particular to double-edged tool.

Background

The alloy blade of traditional diamond structure only has a blade, and single-edge blade exists the tipping easily, wearing and tearing scheduling problem too fast.

Disclosure of Invention

To above defect, the utility model aims at providing a double-edged tool, aim at solving among the prior art cutter and easily collapse sword, the too fast technical problem of wearing and tearing.

In order to solve the technical problem, the technical scheme of the utility model is that:

the utility model provides a double-cutting-edge tool, includes the rhombus cutter body, is equipped with the locating hole in the middle of the rhombus cutter body, and the rhombus arris department of rhombus cutter body is equipped with the notch, and the notch sets up around rhombus cutter body a week, and the intersection of notch and rhombus cutter body terminal surface is first blade, and the intersection of notch and rhombus cutter body side is the second blade.

Wherein, the section of the notch is V-shaped.

The axial distance between the first cutting edge and the second cutting edge along the positioning hole is 0.1-0.3 mm, and the radial distance between the first cutting edge and the second cutting edge along the positioning hole is 0.25-0.4 mm.

The axial distance between the first cutting edge and the second cutting edge along the positioning hole is 0.3mm, and the radial distance between the first cutting edge and the second cutting edge along the positioning hole is 0.4 mm.

Wherein, the rhombus cutter body is 80 degrees rhombus cutter body.

Wherein, first blade all is the fillet with the second blade and handles, and fillet radius is 0.02 ~ 0.04 mm.

After the technical scheme is adopted, the beneficial effects of the utility model are that:

because the utility model discloses double-edged tool is equipped with the rhombus cutter body of locating hole including the centre, the rhombus limit arris department of rhombus cutter body is equipped with the notch, the notch sets up around rhombus cutter body a week, the intersection of notch rhombus cutter body terminal surface forms first blade, the intersection of notch and rhombus cutter body side forms the second blade, make in the course of working, first blade participates in the cutting simultaneously with the second blade, make first blade and second blade atress simultaneously, two blades carry out effective share to the total atress of rhombus cutter body, greatly reduced first blade and second blade atress, the cutter life and machining efficiency are improved.

To sum up, the utility model provides an among the prior art technical problem that the cutter easily collapses sword, wearing and tearing are too fast, the utility model discloses a processing is participated in simultaneously to two blades, has reduced the atress of the single blade of cutter, has reduced the sword probability that collapses of cutter, has reduced the wearing and tearing of cutter, has prolonged the cutter life-span, has promoted machining efficiency.

Drawings

FIG. 1 is a schematic structural view of the double-edge cutting tool of the present invention;

fig. 2 is a sectional view taken along a line a-a in fig. 1.

In the figure, 1 is a diamond cutter body, 10 is an end face, 11 is a side face, 12 is a notch, 13 is a first cutting edge, 14 is a second cutting edge, and 15 is a positioning hole.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The position that involves in this specification all takes the position of the utility model discloses when double-edged tool normally works as the standard, does not restrict the position when its storage and transportation, only represents relative position relation, does not represent absolute position relation.

As shown in fig. 1 and 2, the double-cutting-edge tool comprises a rhombic tool body 1, wherein the rhombic tool body 1 is preferably an 80-degree rhombic tool body 1, a positioning hole 15 is formed in the center of the rhombic tool body 1, notches 12 are formed in two rhombic edges of the rhombic tool body 1, the cross section of each notch 12 is preferably a V shape, and other types such as an arc shape and a bevel edge shape are applicable. The notch 12 surrounds the diamond-shaped edge of the diamond-shaped cutter body 1 for a circle, so that the notch 12 is convenient to machine and form, and has the function of containing scraps. The notch 12 divides the diamond-shaped edge of the diamond-shaped cutter body 1 into two parts, the two parts are respectively a first cutting edge 13 and a second cutting edge 14, two diamond-shaped surfaces of the diamond-shaped cutter body 1 are end surfaces 10, a vertical surface surrounding the diamond-shaped surfaces for a circle is a side surface 11, the intersection of one groove surface of the notch 12 and one end surface 10 of the cutter body is the first cutting edge 13, the intersection of the other groove surface of the notch 12 and the side surface 11 of the cutter body is the second cutting edge 14, the axial distance between the first cutting edge 13 and the second cutting edge 14 along the positioning hole 15 is 0.1-0.3 mm, and the radial depth of the notch 12 along the positioning hole 15 is 0.25-0.4 mm. Preferably, the axial depth of the notch 12 along the positioning hole 15 is 0.3mm, and the radial depth of the notch 12 along the positioning hole 15 is 0.4mm, so as to ensure the cutting feed capability of the first cutting edge 13 and the second cutting edge 14. When the cutting tool is used, the first cutting edge 13 and the second cutting edge 14 participate in cutting at the same time, so that the first cutting edge 13 and the second cutting edge 14 are stressed at the same time, the total stress of the diamond-shaped tool body 1 is effectively shared by the two cutting edges, the stress of the first cutting edge 13 and the stress of the second cutting edge 14 are greatly reduced, and the service life and the processing efficiency of the cutting tool are improved.

Preferably, first blade 13 all is the rounding off with second blade 14 and is handled for increase double-edged tool's life, guarantee that fillet radius is 0.02 ~ 0.04 mm.

The present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes without creative labor from the above conception, and all the changes fall within the protection scope of the present invention.
