Description
Technical field
The utility model, which belongs to, bores chip technology field, and in particular to a kind of special-shaped brill piece.
Background technology
It is relatively conventional structure that abnormity, which bores piece, is mainly used for special occasion and carries out brill processing, traditional technology it is different
Although shape bores piece and can meet the use demand of ordinary circumstance, chip generation is had when in use due to boring piece, and it is existing
The abnormity of technology bores piece there is no corresponding chip removal structure, and the presence of too many chip can not only influence to bore the normal use of piece,
And brill piece is easily damaged, applicability and practicability are restricted.
The content of the invention
The purpose of this utility model is to provide the special-shaped brill piece that a kind of structure setting is reasonable and stability in use is good.
The technical solution for realizing the utility model aim is a kind of special-shaped brill piece, and including drill body, the drill body includes one
Molding drill lip portion and muscle bar portion, and drill lip portion and muscle bar portion, into " 7 " character form structure, the width in the drill lip portion is more than muscle bar portion
Width, set that there are two isosceles trapezoid guiding face and two isosceles trapezoid guiding faces with muscle bar between drill lip portion and muscle bar portion
The center line symmetrical setting in portion, the long base of isosceles trapezoid guiding face are in drill lip portion, are set on isosceles trapezoid guiding face
There is dust lead groove, be additionally provided in drill lip portion and tiltedly draw face, the face of tiltedly drawing is separately positioned on drill lip with isosceles trapezoid guiding face
The both sides in portion, it is described tiltedly draw between Middle face and muscle bar portion have cooling liquid guiding channel.
The bottom surface in the drill lip portion is to be in isosceles trapezoid with the horizontal the inclined surface at 18 degree of angles and the bottom of inclined surface
At guiding face, top be in tiltedly draw at face.
The width of the muscle bar portion is 6.4mm, and the width in the drill lip portion is 15.3mm.
The utility model has positive effect：The structure setting of the utility model is reasonable, not only can effectively realize
Dust lead operates, and can have makes cooling liquid directly reach drill lip portion, so as to the service life for being conducive to improve drill body and using steady
It is qualitative, strong applicability and practicability is good.
Description of the drawings
In order to which the content for making the utility model is more likely to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, wherein：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the utility model, and wherein Fig. 1 is the structural representation of the utility model
Figure.
See Fig. 1, a kind of special-shaped brill piece, including drill body 1, the drill body 1 includes integrally formed drill lip portion 2 and muscle bar portion 3,
And drill lip portion and muscle bar portion, into " 7 " character form structure, the width in the drill lip portion 2 is more than the width of muscle bar portion 3, drill lip portion 2 with
Between muscle bar portion 3 set there are two isosceles trapezoid guiding face 4 and two isosceles trapezoid guiding faces it is symmetrical with the center line of muscle bar portion
It setting, the long base of isosceles trapezoid guiding face 4 is in drill lip portion, and dust lead groove 5 is provided on isosceles trapezoid guiding face 4,
It being additionally provided in drill lip portion 2 and tiltedly draws face 6, the face of tiltedly drawing is separately positioned on the both sides in drill lip portion with isosceles trapezoid guiding face,
It is described tiltedly draw between Middle face and muscle bar portion have cooling liquid guiding channel 7.
The bottom surface in the drill lip portion is to be in isosceles trapezoid with the horizontal the inclined surface at 18 degree of angles and the bottom of inclined surface
At guiding face, top be in tiltedly draw at face.
The width of the muscle bar portion is 6.4mm, and the width in the drill lip portion is 15.3mm.
The structure setting of the utility model is reasonable, not only can effectively realize that dust lead operates, and can have and make cooling liquid
Drill lip portion is directly reached, so as to be conducive to improve the service life and stability in use of drill body, strong applicability and practicability is good.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
It is exhaustive.And the obvious changes or variations that these connotations for belonging to the utility model are extended out still falls within this practicality
New protection domain.
