Abstract
The invention relates to a drill bit with heat dissipation holes in a blade portion. The drill bit comprises a drill bit body, the blade portion and the heat dissipation holes. The blade portion is arranged at one end of the drill bit body, and the heat dissipation holes are formed in the blade portion and penetrate through the whole blade portion. The drill bit is good in heat dissipation performance and long in service life, and scrapping of the product is greatly reduced.
Description
Technical field
The present invention relates to drill bit, be specifically related to a kind of blade band louvre drill bit.
Background technology
Nowadays, producing when machinofacture, the drill bit instrument that is absolutely necessary, drill bit is in the time using at a high speed, and caloric value is very big, and blade often ruptures, and is mainly because the heat of blade cannot be discharged and cause in time, increases extra production cost to enterprise.
Summary of the invention
The object of this invention is to provide a kind of blade 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 blade 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 on blade, and louvre runs through whole blade.
Described drill body is white steel, and wolfram steel material is made, and shape can be circle, rectangle and other shape.
Described louvre, on blade, and runs through each blade.
The shape of described louvre can be circular, the shapes such as rectangle.
The sword number of described blade can freely design.
Advantage of the present invention and good effect are: 1. good heat dissipation; 2. long service life; 3. reduce greatly scrapping of causing to product.
Brief description of the drawings
Fig. 1 is a kind of blade band louvre drill bit.
Wherein: 1, drill body, 2, blade, 3, louvre.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of blade band louvre drill bit, as Fig. 1, shown in Fig. 2, it comprises drill body 1, blade 2, louvre 3; Described blade 2 is in one end of drill body 1, and louvre 3 is on blade 2, and louvre 3 runs through each blade 2, forms blade band louvre drill bit.
Concrete operations are as follows: first on drill body 1 load facility, when after opening of device, blade 2 is processed processed product, the heat producing is shed with drill body 1 by the louvre 3 on blade 2, thereby reduce the heat on blade 2 with the fastest speed, increased the service life of blade 2.
In the present invention, as becoming row embodiment, the shape of louvre can be circular, the shapes such as rectangle.Therefore the scope that the scope of the present invention limits with claims is as the criterion.
Claims (5)
