Embodiment 1

[0040] In this embodiment, the side view structure of the groove 7 is as Figure 4 Shown. The first groove wall 71 and the second groove wall 72 are symmetrical about the transverse central section S2 of the cutter wheel, and the platforms 73 are both convex arc-shaped platforms, extending from the circumferential edge 6 to the bottom of the groove 7 In terms of the above, the height h between adjacent platforms gradually increases, and the angle θ between adjacent platforms gradually increases. As the distance between the two cones gradually increases, the surface area of ​​the platform gradually increases.

[0041] In this embodiment, while the angle θ gradually increases every 10°, the height h of the platform gradually increases every 0.5um, so as to ensure that each platform participates in cutting.

[0042] It should be noted that the arc-shaped platform in this example can only be convex but not concave, otherwise it will not play the role of secondary cutting. The cutting ...

Embodiment 2

[0044] In this embodiment, the side view structure of the groove 7 is as Figure 5 Shown. The first groove wall 71 and the second groove wall 72 are symmetrical with respect to the transverse central section S2 of the cutter wheel, and the platforms 73 are both convex trapezoidal platforms, in the extending direction from the circumferential edge 6 to the bottom of the groove 7 , The height h of adjacent platforms gradually increases, and the angle θ between adjacent platforms gradually increases. As the distance between the two cones gradually increases, the surface area of ​​the platform gradually increases. As a linear platform, the convex trapezoidal platform can make the cutter wheel have the advantages of small tangent line damage, smooth cutting line, flat cutting section, and uniform crack depth. In this embodiment, while the included angle θ gradually increases every 5°-10°, the height h of the platform gradually increases every 0.2-0.5um to ensure that each platform p...

Abstract

The invention discloses a knife wheel with platforms. The knife wheel comprises two symmetrical disk faces and a shaft hole for mounting a knife shaft, wherein the shaft hole is positioned in the center of the knife wheel and transversely extends to the disk faces; the disk faces extend to a longitudinal center cross section of the knife wheel along the outer edge and are intersected to form two symmetrical tapered faces; an intersection line of the tapered faces forms a peripheral edge; grooves are uniformly formed in the peripheral edge; cross sections of openings of the grooves are V-shaped; the openings of the grooves extend to a transverse center cross section of the knife wheel along the peripheral edge and are intersected to form first groove walls and second groove walls; the firstgroove walls and the second groove walls bulge outwards to form at least two platforms; and the platforms transversely extend to the tapered faces to form inner edges. According to the knife wheel with the platforms, a wear degree of the edges is reduced in a cutting process by dispersing cutting pressure at the edges; a cutting life is prolonged; at the same time, the platforms serve as the facial inner edges and can assist in cutting; a cutting scope is enlarged; and the inner edges formed by the platforms can allow a cutting pressure scope and an application scope of the knife wheel to bewider.

Description

Technical field [0001] This application relates to the field of tool processing, and in particular to a cutter wheel with a platform. Background technique [0002] The tool for cutting brittle materials such as glass is generally a disc-shaped cutter wheel. The commonly used cutter wheel consists of a shaft hole, a two-sided symmetrical disc surface, two intersecting cone surfaces, and a cutting edge. The basic structure of the cutter wheel is that the center of the disc surface is provided with a shaft hole for installing the cutter shaft. The outer edges of the disc surfaces on both sides extend outward into two symmetrical tapered surfaces. The two cone surfaces intersect to form the circumferential edge of the cutter wheel, along the circumferential direction of the circumferential edge. The spaced distribution has concave tooth-shaped grooves. The tooth-shaped groove is composed of two symmetrical groove surfaces formed at the top ends of the two conical surfaces. The inter...
