Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 4, the present invention provides a diamond saw blade for high efficiency cutting, which comprises a disk substrate 2 and a cutting head 1 disposed at the radial edge of the disk substrate 2 at a distance, wherein the cutting head 1 has a radial cutting surface 11 and a radial connecting surface 12, the radial connecting surface 12 is welded or connected with the disk substrate 2, the radial cutting surface 11 is used for directly contacting with a material to be cut, and the rotation direction of the disk substrate 2 is the cutting direction, specifically the direction of the arrow in fig. 1.

The axial both sides of tool bit 1 are equipped with a plurality of cutting grooves 13 of arranging along the cutting direction, cutting grooves 13 are the V style of calligraphy and cutting grooves 13 includes the first point portion 14 of pointing to the cutting direction.

Therefore, the V-shaped cutting grooves 13 enable two axial sides of the cutter head 1 to form sharp parts capable of cutting, when the cutter head 1 cuts a material to be cut into an opening, the material to be cut continues to penetrate into the opening gradually for cutting, at the moment, the two axial sides of the cutter head 1 are in contact with the material to be cut and the side parts of the opening are assisted by the cutting grooves 13, the opening is accelerated to penetrate further, sharp cutting points are additionally arranged on the two axial sides of the cutter head 1, and therefore cutting efficiency is improved. In addition, the cutting groove 13 has a short clearance with the material to be cut, and the air flow in the clearance can be accelerated at the high-speed operation of the disc substrate 2, thereby realizing rapid heat removal.

For example, in the diamond blade disclosed in the chinese utility model 201220012723.X, a groove is formed in the disc substrate between two adjacent diamond tool bits to facilitate chip removal, and the groove has a long strip-shaped structure, so that a chip removal space is small. The disc base body 2 is provided with a chip groove between two adjacent cutter heads 1, the chip groove comprises a V-shaped groove 22 and a circular groove 23 which are connected, and the V-shaped groove 22 comprises a second tip portion 24 pointing to the cutting direction. Because the cutting groove 13 is additionally provided with the cutting surface, the scraps are increased at the same time, the scrap discharging space is increased by combining the V-shaped groove 22 and the circular groove 23, and the scraps can be discharged to two sides of the V-shaped groove 22, so that the scrap discharging speed is accelerated, and the influence on cutting caused by accumulation of the scraps is avoided. Compared with the prior art, the present case has both improved the cutting efficiency of tool bit 1, improves disc base member 2 simultaneously and makes its cooperation tool bit 1 accelerate chip removal efficiency, and then improves holistic cutting efficiency.

Moreover, the disc matrix also has the effects of vibration reduction, noise reduction and cracking prevention after being grooved.

In addition, the long-strip-shaped groove also increases the wind resistance and consumes the rotation energy of the disc base body 2, and the V-shaped groove 22 of the scheme is a flow guide structure capable of reducing the wind resistance, so that the air flow resistance can be reduced, the energy consumption is reduced, and the heat dissipation is facilitated.

The disc base body 2 further comprises a plurality of silencing holes 25, vibration transmission in cutting of the disc base body 2 is reduced, noise is low, and the heat dissipation effect is good.

Preferably, two oblique groove surfaces 15 are formed on two sides of the cutting groove 13 in the cutting direction, and a sharp corner 16 is formed on one side of the cutting groove 13, that is, the axial section of the cutting groove 13 is in a trapezoidal structure, the conventional tool bit 1 only has one radial cutting surface 11 and two tips at two ends of the radial cutting surface 11 for cutting, the oblique groove surfaces 15 form new cutting surfaces, and the sharp corner 16 forms a new cutting tip, so that the cutting action area is greatly increased, and the cutting efficiency is further improved.

Preferably, both radial ends of the cutting flutes 13 extend to the radial cutting faces 11 and radial connecting faces 12 of the cutting head 1. Thus, the radial direction of the cutting groove 13 is a through structure, so that not only can waste chips cut by the radial cutting surface 11 be discharged in time, but also the heat of the radial cutting surface 11 can be discharged, and the deformation of the cutter head 1 is prevented.

Preferably, in the cutting process, the material to be cut also has a reaction force on the cutter head 1, and the cutting grooves 13 on the two axial sides of the cutter head 1 are arranged in a staggered manner, so that the two sides of the cutter head 1 are stressed more uniformly in the cutting process and are not easy to break.

Preferably, the radial cutting surface 11 and the axial both sides of tool bit 1 all are equipped with a plurality of row diamond particle 17, and two adjacent rows of diamond particle 17 are crisscross to be arranged, and even distribution does benefit to and treats even application of force of cutting material, realizes even cutting, avoids tool bit 1 body to influence life because of wearing and tearing inhomogeneous.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
