High-permeability glass cutter wheel with chamfer on side edge of concave part of cutting edge

Abstract

The invention relates to a high-permeability glass cutter wheel with a chamfer on the side edge of a concave part of a cutting edge. The cutter wheel is provided with a V-shaped cutting edge part, a disc surface and a shaft hole, wherein the V-shaped cutting edge part comprises a first curved surface S1, a second curved surface S2 and an outer edge ridge L. The cutting edge and the concave part are formed on the periphery of the outer edge ridge L of the V-shaped cutting edge part; and a first chambering oblique surface and a second chambering oblique surface which are symmetrical with each other are formed on the side edge of the concave part. Due to the adoption of the structure, the blockage of glass chips in the concave part of the cutter wheel can be avoided or reduced, the cutting pressure is reduced, and a destructive fracture line at the cutting edge of glass is reduced, so that the glass cutting quality is improved, and the service life of the cutter wheel for cutting the glass is improved.

Description

technical field [0001] The invention relates to a high-permeability glass cutting cutter wheel with a concave edge and chamfered side edges, which belongs to the technical field of processing and cutting tools. Background technique [0002] Japan's MDI Corporation has announced an invention patent with the patent number 96101939.5. The feature of this patent is that regular gaps are processed on the outer circular ridge line of the cutter wheel, thereby increasing the glass cutting depth and improving the cutting quality. This patent made MDI company get a good development. But the notch processed on the ridgeline of the outer circular cutting edge described in this patent often has a wider bottom. The ridged cutting edge of the cutter wheel with this structure improves the penetration of cutting, but the table top at the bottom of the depression will increase the glass cutting pressure and cause a certain degree of damage to the glass cutting surface. [0003] In 2008, Be...

The ridged edge of the cutter wheel with this structure improves the penetration of cutting, but the table top at the bottom of the depression will increase the glass cutting pressure and cause a certain degree of damage to the glass cutting surface

[0003] In 2008, Beidou Diamond Company applied for a cutter wheel with double cutting edges, and the patent publication number is CN101745990A; this patented product can solve the obstruction and damage effect of the concave bottom platform on glass cutting in the patent of MDI Company, but its cutting edge and The included angle of the notch is an acute angle, and the tip of the tooth is easy to break during cutting, resulting in reduced cutting quality and short life of the cutter wheel
