Fig. 2 is a kind of overlooking structure figure of triangle alloy cutter head of the utility model embodiment
Specific embodiment
The utility model implementation method is described further below in conjunction with the accompanying drawings：
As shown in Figure 1-2, the utility model is a kind of triangle alloy cutter head, in order to the cutting operation for lifting existing drill bit is imitated
Benefit, this triangle alloy cutter head includes the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 and and rounded uniform arrangement is linked as one
Body, the inner side of described the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 is higher than outside to make the first cutting blade 1, the and of the second cutting blade 2
The upper end of the 3rd cutting blade 3 is oblique respectively；By setting the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3, so work as drill bit
In operation, electric drill often drives bit one week, can increase the cutting output of a piece of cutting blade than existing drill bit accordingly, so
The cutting benefit of drill bit can be obviously improved 1/3rd, and identical workload is corresponding using its activity duration of this triangle alloy cutter head
Meeting shorten, reduce the activity duration and can effectively extend the service life of drill bit；And by the first cutting blade 1, the second cutting blade 2 and the 3rd
The inner side of cutting blade 3 sets higher than outside oblique, and the junction of such first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 is just
A summit can be formed, during drilling work, is easy to the positioning of alloy cutter head, and the first cutting blade 1, the and of the second cutting blade 2
3rd cutting blade 3 is oblique, and so when drill bit is in operation, more preferably, cutting benefit can be more preferably for its cutting angle.Certainly, close
Golden cutter head can also use more cutting edge structures, such as set five cutting blades, form five jiaos of alloy cutter heads, the cutting of such drill bit
Benefit can be higher, depending on can specifically being required according to the market demand or user.
In the present embodiment, in order to improve the cutting benefit of alloy cutter head, described the first cutting blade 1, the second cutting blade 2 and
The section of three cutting blades 3 is arc；Arc is set to by by the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3, is so made in cutting
During industry, the first cutting blade 1, the second cutting blade 2 and the contact area between the 3rd cutting blade 3 and cutting object can be effectively increased, improve cutting
Cutting output during operation, so as to shorten the activity duration of cutting, lifts the operational benefit of cutting；Certainly, the first cutting blade 1, second
The cutting blade 3 of cutting blade 2 and the 3rd can also be not configured to arc, as straight in being arranged to, and equally can reach the purpose for improving operational benefit, but
It is arranged to straight, the first cutting blade 1, the second cutting blade 2 and the contact area between the 3rd cutting blade 3 and cutting object are cut not as arc
Sword is big, and its cutting output is also relative will to be lacked, therefore, the implementation method of the present embodiment is preferred embodiments.
In the present embodiment, in order to improve the cutting output of arc cutting blade, described the first cutting blade 1, the second cutting blade 2 and the 3rd
The section arc R radiuses of cutting blade 3 are 16 ° ± 5 °, preferably 16 °, greater or lesser radius are may also set up certainly, but if setting
Radius is put more than this value range, this can cause the arc of curvature of the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 too small, make first
Cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 are smaller with the contact area of cutting object, it is impossible to lift the cutting output of drill bit；And if
Smaller radius is set, then the arc of curvature of the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 can be caused larger, make the first cutting blade
1st, the second cutting blade 2 and the 3rd cutting blade 3 Yi Fahui in cutting operation break, therefore, the implementation method of the present embodiment is preferred real
Apply mode.
In the present embodiment, to ensure the first cutting blade 1, the second cutting blade 2 and the intensity of the 3rd cutting blade 3, prevent from making in cutting
It is broken during industry, the width d of described the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 is 2mm~5mm, preferably
2.5mm, certainly, the size also dependent on drill bit increases its thickness accordingly, but can not only ensure first using the technical program
The working strength of cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3, prevents fracture, meanwhile, can also farthest reduce and be produced into
This, therefore, the implementation method of the present embodiment is preferred scheme.
In the present embodiment, in order to ensure the cutting benefit of triangle alloy cutter head, described the first cutting blade 1, the second cutting blade 2
And the 3rd the upper surface of cutting blade 3 be respectively equipped with anterior angle 4 and relief angle 5, the described angle of anterior angle 4 is 30 ° ± 10 °, preferably 30 °；
The angle of relief angle 5 is 60 °, preferably ± 10 °, 60 °；30 ° and 60 ° are respectively set to by by the angle of anterior angle 4 and relief angle 5, this
Sample can farthest ensure cutting operation benefit and prevent the fracture of the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3；When
So, also can the angle of anterior angle 4 and relief angle 5 be respectively provided with bigger or is reduced, but examination is repeated several times by the applicant, at this
The greatest benefit of cutting operation can be ensured in the angular range of technical scheme, therefore, the implementation method of the present embodiment is preferred real
Apply mode.
In the present embodiment, in order to ensure the degree of being connected firmly between the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3,
The intensity of triangle alloy cutter head is lifted, the junction of described the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 is provided with circular arc mistake
Angle 6 is crossed, the radius at the transition angle 6 is 2 °~5 °；By the connection between the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3
It is 2 °~5 ° transition angles 6 that place sets radius, preferably 2 °, so can effectively ensure that the first cutting blade 1, the second cutting blade 2 and the 3rd are cut
Bonding strength between sword 3, is prevented effectively from the fracture of the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3, extends it and uses the longevity
Life.
In the present embodiment, it is so relative because the section of the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3 is arc
The end angle for making cutting blade it is more sharp, in order to prevent cutting blade from collapsing angle, described the first cutting blade 1, the second cutting blade 2 and
Three cutting blades 3 and end are respectively equipped with entrance angle 7, and the width of the entrance angle 7 is the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3
2/5ths of width and its angle be 13 ° ± 2 °；Set by the end of the first cutting blade 1, the second cutting blade 2 and the 3rd cutting blade 3
Put entrance angle 7, its width for cutting blade width 2/5ths, angle be 13 ° ± 2 °, so reduce accordingly the first cutting blade 1,
The sharpness of the second cutting blade 2 and the entrance angle 7 of the 3rd cutting blade 3, when cutting operation is carried out, so that it may effectively prevent the first cutting blade 1, the
Two cutting blades 2 and the 3rd cutting blade 3 collapse angle, so as to the service life of triangle alloy cutter head and making for operating personnel can effectively be extended
Use security.
Above-described embodiment is not construed as to limitation of the present utility model, but any is made based on spirit of the present utility model
Improve, all should be within protection domain of the present utility model.
