Abstract
The invention relates to a drill bit with heat radiation holes on a side face. The drill bit comprises a drill bit body, edge parts and the heat radiation holes, wherein the edge parts are arranged at one end of the drill bit body and the heat radiation holes are formed among the edge parts; the heat radiation holes are through holes. According to the drill bit with the heat radiation holes on the side face, the heat radiation of a product is good; the service life of the drill bit body and the edge parts is long; the scrapping to the product is reduced greatly.
Description
Technical field
The present invention relates to drill bit, be specifically related to a kind of side band louvre drill bit.
Background technology
Nowadays, when producing machinofacture, the drill bit instrument that is absolutely necessary, in use, caloric value is very big for drill bit, main by drill body heat radiation, because thermal diffusivity is bad, often cause Drill Crack phenomenon, sometimes directly break in product the inside, cause product rejection ，Gei enterprise to increase extra production cost.
Summary of the invention
The object of this invention is to provide a kind of side band louvre drill bit, this drill bit is to overcome the deficiencies in the prior art.
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is: a kind of side band louvre drill bit, it is characterized in that, and it comprises drill body, blade, louvre; Described blade is in one end of drill body, and louvre is between blade, and louvre is through hole.
Described drill body is white steel, and wolfram steel material is made, and shape can be circle, rectangle and other shape.
Described louvre is between blade.
The shape of described louvre can be the shapes such as circle, rectangle.
The sword number of described blade can freely design.
Described louvre be the louvre of marshalling, quantity can freely design.
Advantage of the present invention and good effect are: 1. good heat dissipation; 2. drill body and blade long service life; 3. reduce greatly scrapping of causing to product.
Accompanying drawing explanation
Fig. 1 is a kind of side band louvre drill bit.
Wherein: 1, drill body, 2, blade, 3, louvre.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A band louvre drill bit, as shown in Figure 1, it comprises drill body 1, blade 2, louvre 3; Described blade 2 is in one end of drill body 1, and louvre 3 is between blade 2, and louvre 3 is through-hole type, forms side band louvre drill bit.
Concrete operations are as follows: first on drill body 1 load facility, after opening of device, 2 pairs of processed products of blade are processed, the heat producing is shed with drill body 1 by the louvre 3 between blade 2, thereby with the fastest speed, reduce the heat on blade 2 and drill body 1, drill body 1 and the service life of blade 2 are increased.
In the present invention, as becoming row embodiment, the shape of louvre can be the shapes such as circle, rectangle.Therefore the scope that the scope of the present invention limits with claims is as the criterion.
Claims (6)
1. a side band louvre drill bit, is characterized in that, it comprises drill body, blade, louvre; Described blade is in one end of drill body, and louvre is between blade, and louvre is through hole.
2. a kind of side according to claim 1 band louvre drill bit, described drill body is white steel, and wolfram steel material is made, and shape can be circle, rectangle and other shape.
3. a kind of side according to claim 1 band louvre drill bit, described louvre is between blade.
4. a kind of side according to claim 1 band louvre drill bit, the shape of described louvre can be the shapes such as circle, rectangle.
5. a kind of side according to claim 1 band louvre drill bit, the sword number of described blade can freely design.
