Description
Technical field
The utility model, which belongs to, bores chip technology field, and in particular to a kind of trapezoidal brill piece.
Background technology
Need to bore piece using special-shaped in the drilling situation of some occasions, but it is traditional it is special-shaped bore piece its there is no corresponding
Dust lead structure, piece damage is bored at abnormal shape to be very easy to chisel when in use, simultaneously because the special-shaped structure for boring piece is more special
Very, thus will be higher to chip removal requirement, the special-shaped demand bored piece and just cannot be satisfied market at all of traditional technology.
Invention content
The purpose of this utility model is to provide the trapezoidal brill piece that a kind of structure setting is reasonable and stability in use is good.
Realize that the technical solution of the utility model aim is a kind of trapezoidal brill piece, including drill body, the cross section of the drill body
For right-angled trapezium, there are inclined guide surface, inclined guide surface, at 35 degree of acute angles, inclining with horizontal plane between the drill lip and brill top of drill body
At least three dust lead grooves are evenly arranged on oblique guiding face, at least two are evenly arranged on the inclined surface of right-angled trapezium and is led
To groove, the one end for being oriented to groove extends to the other end in inclined guide surface and extends on the top surface of drill body, in the drill body
U-shaped groove is provided in the middle part of top surface, the dust lead groove and guiding groove are connected with U-shaped groove.
The tail portion of drill body is provided with v-depression, the v-depression is separately positioned on the both ends of drill body with drill lip.
The a length of 10mm in bottom edge, a length of 5.5mm of top margin and a height of 6.5mm of the right-angled trapezium.
The utility model has the effect of positive：The structure setting of the utility model is reasonable, can effectively complete dust lead
Operation, to be conducive to improve the stability in use of drill lip, while when using cooling liquid is injected also can by dust lead groove and
It is oriented to groove and directly reaches drill lip, so as to timely and effectively cool down to drill lip, be conducive to improve its service life, make
It is good with stability, strong applicability and practicability is good.
Description of the drawings
In order to make the content of the utility model be 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 structural schematic diagram of the utility model.
Specific implementation mode
(embodiment 1)
Fig. 1 shows that a kind of specific implementation mode of the utility model, wherein Fig. 1 are the structural representation of the utility model
Figure.
See Fig. 1, a kind of trapezoidal brill piece, including drill body 1, the cross section of the drill body 1 is right-angled trapezium, the drill lip 2 of drill body 1
There are inclined guide surface 4, inclined guide surface, at 35 degree of acute angles, to be uniformly arranged in inclined guide surface 4 with horizontal plane between being pushed up with brill
There are at least three dust lead grooves 5, at least two guiding grooves 6 are evenly arranged on the inclined surface of right-angled trapezium, are oriented to groove 6
One end extend to the other end in inclined guide surface 4 and extend on the top surface of drill body 1, be provided in the middle part of the top surface of the drill body
U-shaped groove 3, the dust lead groove 5 and guiding groove 6 are connected with U-shaped groove 3.
The tail portion of drill body is provided with v-depression 7, the v-depression is separately positioned on the both ends of drill body with drill lip.
The a length of 10mm in bottom edge, a length of 5.5mm of top margin and a height of 6.5mm of the right-angled trapezium.
The structure setting of the utility model is reasonable, can effectively complete dust lead operation, to be conducive to improve drill lip
Stability in use, while also drill lip can be directly reached by dust lead groove and guiding groove when using injection cooling liquid, to
It can timely and effectively cool down to drill lip, be conducive to improve its service life, stability in use is good, strong applicability and practicality
Property 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 fall within this practicality
Novel protection domain.
