Abstract

The utility model discloses a drill bit with diamond dust granule, including drillstock, drill neck, drill tip, the drillstock be the cylinder structure, one end is connected the drill neck, the drill neck other end is connected the drill tip, the drill neck on be equipped with a spiral chip groove, the drill tip is equipped with two cutting edges, two the cutting edge use the the central axis of drillstock to be screw set as the center, drill neck and drill tip on the surface uniform application have the diamond dust granule. In this way, the utility model discloses simple structure only is provided with a chip groove, ensures the width of chip groove, guarantees that the chip removal is unobstructed, simultaneously, sets up the diamond dust granule on the surface at the drill neck drill tip, and diamond dust hardness is big, effectively avoids the drill neck wearing and tearing, and antioxidant activity is good, and is indeformable under high temperature, can guarantee that the hole of boring is highly polished, and the sand trace is few and shallow.

Description

A kind of drill bit with particles of silicon carbide

Technical field

This utility model relates to field of drill, particularly relates to a kind of drill bit with particles of silicon carbide.

Background technology

Drill bit is the cutter that boring is conventional, drill bit is when boring, mainly through bit tip, workpiece is cut, by chip area, chip is discharged, if the discharge that chip can not be much smoother, then can cause that cut occurs in the hole inwall bored, even result in workpiece and become waste product, existing drill bit usually arranges three chip areas, and chip area is narrow, and chip removal is slow, it is easily caused hole inwall and cut occurs, also can affect the bright and clean degree of hole inwall flour milling plus the material of drill bit, it is many that this allows for the hole inwall sand trace that drill bit gets out, and drilling effect is poor.

Utility model content

This utility model, mainly solving the technical problems that provide a kind of drill bit with particles of silicon carbide, has chip removal unobstructed, and carefully and uniformly, sand trace is few and shallow for flour milling.

For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of drill bit with particles of silicon carbide, it is characterized in that, including: drillstock, drill neck, apex point, described drillstock is cylindrical structure, one end connects described drill neck, the described drill neck other end connects described apex point, described drill neck is provided with a helical form chip area, described apex point is provided with two cutting edges, two described cutting edges are helically arranged centered by the central axis of drillstock, and described drill neck has particles of silicon carbide with uniformly dispersing on apex point surface.

In one preferred embodiment of this utility model, the helical angle of described chip area is 30 °-45 °.

In one preferred embodiment of this utility model, the angle of described apex point is 135 °.

In one preferred embodiment of this utility model, described particles of silicon carbide adopt plating, hot pressing, welding method be fixed on the drill neck of drill bit, apex point surface.

The beneficial effects of the utility model are: this utility model simple in construction, only it is provided with a chip area, it is ensured that the width of chip area, it is ensured that chip removal is unobstructed, simultaneously, arranging particles of silicon carbide on drill neck apex point surface, corundum hardness is big, is prevented effectively from drill neck abrasion, antioxygenic property is good, at high temperature indeformable, it is possible to ensureing that the hole bored is highly polished, sand trace is few and shallow.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:

Fig. 1 is the structural representation of a kind of drill bit one preferred embodiment with particles of silicon carbide of this utility model；

Fig. 2 is the structural representation of shown cutting edge；

In accompanying drawing, the labelling of each parts is as follows: 1-drillstock, 2-drill neck, 3-apex point, 4-chip area, 5-cutting edge, 6-particles of silicon carbide.

Detailed description of the invention

Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Referring to Fig. 1 and Fig. 2, this utility model embodiment includes:

A kind of drill bit with particles of silicon carbide, it is characterized in that, including: drillstock 1, drill neck 2, apex point 3, described drillstock 1 is cylindrical structure, and one end connects described drill neck 2, and described drill neck 2 other end connects described apex point 3, described drill neck 2 is provided with a helical form chip area 4, described apex point 3 is provided with two cutting edges 5, and two described cutting edges 5 are helically arranged centered by the central axis of drillstock 1, and described drill neck 2 has particles of silicon carbide 6 with boring uniformly dispersing on 3 point surfaces.

It is different from prior art.

In another embodiment, the helical angle of described chip area 4 is 30 °-45 °, only arranges a chip area, is effectively ensured the width of chip area, keeps chip removal unobstructed.

In another embodiment, the angle of described apex point 3 is 135 °.

In another embodiment, described particles of silicon carbide 6 adopt plating, hot pressing, welding method be fixed on the drill neck of drill bit, apex point surface, its toughness of corundum is strong, advantage is the highly polished of mill part, and sand trace is few and shallow, and flour milling is carefully and uniformly, with low cost, long service life.

Utility model works principle: this utility model simple in construction, only it is provided with a chip area, it is ensured that the width of chip area, it is ensured that chip removal is unobstructed, simultaneously, arranging particles of silicon carbide on drill neck apex point surface, corundum hardness is big, is prevented effectively from drill neck abrasion, antioxygenic property is good, at high temperature indeformable, it is possible to ensureing that the hole bored is highly polished, sand trace is few and shallow.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in scope of patent protection of the present utility model.
