Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the invention.

The first embodiment is as follows:

referring to fig. 1-3, a diamond tool bit with good wear resistance comprises a tool bit main body 1, wherein a plurality of heat dissipation protrusions 2 are arranged on the tool bit main body 1, and two side layers 3 are respectively arranged on two sides of the tool bit main body 1;

the side layer 3 comprises a sheet-like interlayer 301 and a trapezoidal layer 302 having an upper end length of half of a lower end length.

Concretely, tool bit main part 1 and side layer 3 are through brazing fixed welded connection, set up like this and can fix tool bit main part 1 and side layer 3, carry out the abrasionproof protection by side layer 3 to tool bit main part 1, and the brazing technique is comparatively ripe, and the cost is lower.

Specifically, trapezoidal layer 302 up end flushes with 1 up end of tool bit main part, sets up like this and can reduce the regional thickness in trapezoidal layer 302 upper portion, makes the conflict cutting that tool bit main part 1 can be quick wait to cut article, guarantees the cutting sharpness of this tool bit.

Specifically, heat dissipation arch 2 is the arc arch, and heat dissipation arch 2 surfaces are provided with the burr, and the arc arch can improve tool bit main part 1's heat radiating area, and the hydroscopicity of burr is better, can further improve tool bit main part 1's radiating effect through evaporation of water, avoids tool bit main part 1 to lead to the problem of diamond carbonization because the heat siltation that the friction produced leads to the diamond heating in cutting process, has further improved the wear resistance of this tool bit.

Specifically, the abrasive grain concentration of the side layer 3 is twice as high as that of the tool bit main body 1, so that the smoothness of the side layer 3 is high, the material is cut through the tool bit main body 1, and the upper end face of the tool bit is prevented from becoming spherical.

Specifically, the wear resistance of the bonding agent adopted by the side layer 3 is one point and one time of the wear resistance of the bonding agent adopted by the tool bit main body 1, and the wear resistance of the side layer 3 can be improved by the arrangement.

Specifically, the thickness of the side layer 3 is one third of the thickness of the tool bit main body 1, and the advantage that the sharpness of the tool bit main body 1 is high is facilitated to be exerted by the thickness proportion, and meanwhile, the wear resistance of the side layer 3 is ensured, and the tool bit main body 1 is protected by the side layer 3.

Example two:

the difference between this embodiment and the first embodiment is:

specifically, the abrasive grain concentration of the side layer 3 is one point three times of that of the tool bit main body 1, so that the material cost of the diamond is increased, the smoothness of the side layer 3 is higher, and the cutting effect of the tool bit main body 1 is more obvious.

Specifically, the bonding agent wearability that side layer 3 adopted is one point two times the bonding agent wearability that tool bit main part 1 adopted, sets up like this and makes tool bit main part 1 protrusion effect unobvious, has reduced sharpness, has nevertheless improved side layer 3's wearability.

Example three:

the difference between this embodiment and the first embodiment is:

concretely, tool bit main part 1 and side layer 3 pass through laser welding fixed weld connection, and laser welding makes the residue in the middle of tool bit main part 1 and side layer 3 less, and it is more firm to bond.

Specifically, the abrasive grain concentration of the side layer 3 is one to five times of that of the tool bit main body 1, so that the material cost of diamond is further increased, the smoothness of the side layer 3 is further higher, and the cutting effect of the tool bit main body 1 is more obvious.

Specifically, the bonding agent wearability that side layer 3 adopted is one bit four times the bonding agent wearability that tool bit main part 1 adopted, sets up like this and makes tool bit main part 1 protrusion effect unobvious, has reduced the sharpness, has nevertheless further improved side layer 3's wearability.

The working principle is as follows: the tool bit is fixed on the edge of a diamond saw blade in a welding mode, one end of the trapezoid layer 302 is outward, then the diamond saw blade is driven to rotate by power equipment, the tool bit is driven to rotate by the diamond saw blade, the side layer 3 is firstly contacted with a material to be cut in the rotating process of the tool bit, the abrasive concentration of the side layer 3 is one point two to one point five times of that of the tool bit main body 1, therefore, the side layer 3 is softer than the tool bit main body 1, but the sharpness is inferior to the tool bit main body 1, the loss of the side layer 3 is faster, the tool bit main body 1 keeps protruding, the upper end face of the tool bit is prevented from becoming spherical, the cutting sharpness of the tool bit is ensured, the thickness of the upper area of the trapezoid layer 302 can be reduced by the design of the trapezoid layer 302, the material to be cut can be rapidly cut by the tool bit main body 1, and the cutting sharpness of the tool, the binder wearability that the while side layer 3 adopted is one to one bit quadruple for the binder wearability that tool bit main part 1 adopted, this just makes the wearability of side layer 3 better than tool bit main part 1, can play the effect of protection to tool bit main part 1, improve the wearability of this tool bit, the arch 2 that dispels the heat simultaneously has the viscose water, increase heat radiating surface area's effect, can improve the radiating effect to tool bit main part 1, avoid tool bit main part 1 to lead to the problem of diamond carbonization to the diamond heating because the heat siltation that the friction produced in the cutting process, the wearability of this tool bit has further been improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
