Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present invention is described further:
As shown in Figure 1-2, the present invention is a kind of triangle alloy cutter head, in order to promote the cutting operation benefit of existing drill bit,
This triangle alloy cutter head include first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 and and rounded uniform arrangement be connected as a single entity,
First described cutting blade the 1, second cutting blade 2 and inner side of the 3rd cutting blade 3 is higher than outside makes first cutting blade the 1, second cutting blade 2 and the 3rd
The upper end of cutting blade 3 inclined shape respectively；By arranging the first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3, so making when drill bit
During industry, electric drill often drives bit one week, all can increase the cutting output of a piece of cutting blade, such drill bit accordingly than existing drill bit
Cutting benefit can be obviously improved 1/3rd, identical workload uses its activity duration of this triangle alloy cutter head accordingly can
Shorten, reduce the activity duration and can effectively extend the service life of drill bit；And by the first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade
The inner side of 3 arranges the high inclined shape than outside, and the junction of such first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 just can shape
Become a summit, during drilling work, it is simple to the location of alloy cutter head, and first cutting blade the 1, second cutting blade 2 and the 3rd
The most inclined shape of cutting blade 3, so when drill bit is in operation, its cutting angle is more preferable, and cutting benefit can be more preferably.Certainly, alloy knife
Head may be used without more cutting edge structures, such as arranges five cutting blades, forms five jiaos of alloy cutter heads, the cutting benefit of such drill bit
Can be higher, depending on specifically can requiring according to the market demand or user.
In the present embodiment, in order to improve the cutting benefit of alloy cutter head, first described cutting blade the 1, second cutting blade 2 and
The cross section of three cutting blades 3 is arc；By first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 are set to arc, so make in cutting
During industry, the contact area between first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 and cutting object can be effectively increased, improve cutting
Cutting output during operation, thus shorten the activity duration of cutting, promote the operational benefit of cutting；Certainly, the first cutting blade 1, second
Cutting blade 2 and the 3rd cutting blade 3 also can be not configured to arc, as straight in being arranged to, and can reach the purpose improving operational benefit equally, but
Being arranged to straight, the contact area between first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 and cutting object is cut not as arc
Sword is big, its cutting output also relative to lack, therefore, the embodiment of the present embodiment is preferred embodiments.
In the present embodiment, in order to improve the cutting output of arc cutting blade, first described cutting blade the 1, second cutting blade 2 and the 3rd
The cross section arc R radius of cutting blade 3 is 16 ° ± 5 °, preferably 16 °, certainly may also set up greater or lesser radius, if but set
Putting radius more than this value range, this can cause the arc of curvature of first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 too small, makes first
Cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 are less with the contact area of cutting object, it is impossible to promote the cutting output of drill bit；And if
Arrange less radius, then the arc of curvature that can cause first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 is relatively big, makes the first cutting blade
1, the second cutting blade 2 and the 3rd cutting blade 3 Yi Fahui when cutting operation break, and therefore, the embodiment of the present embodiment is the most real
Execute mode.
In the present embodiment, for ensureing the first cutting blade the 1, second cutting blade 2 and intensity of the 3rd cutting blade 3, prevent from making in cutting
Rupturing during industry, first described cutting blade the 1, second cutting blade 2 and the width d of the 3rd cutting blade 3 are 2mm～5mm, are preferably
2.5mm, certainly, it is possible to strengthen its thickness accordingly according to the size of drill bit, but use the technical program not only can ensure first
Cutting blade the 1, second cutting blade 2 and the working strength of the 3rd cutting blade 3, prevent fracture, meanwhile, also can farthest reduce and produce into
This, therefore, the embodiment of the present embodiment is preferred version.
In the present embodiment, in order to ensure the cutting benefit of triangle alloy cutter head, first described cutting blade the 1, 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, described anterior angle 4 angle is 30 ° ± 10 °, preferably 30 °；
Relief angle 5 angle is 60 °, ± 10 °, preferably 60 °；By the angle of anterior angle 4 and relief angle 5 being respectively set to 30 ° and 60 °, this
Sample can farthest ensure cutting operation benefit and prevent the first cutting blade the 1, second cutting blade 2 and fracture of the 3rd cutting blade 3；When
So, it is possible to the angle of anterior angle 4 and relief angle 5 be respectively provided with bigger or reduce, examination is repeated several times, at this but by the applicant
Can ensure the greatest benefit of cutting operation in the angular range of technical scheme, therefore, the embodiment of the present embodiment is the most real
Execute mode.
In the present embodiment, in order to ensure the degree of being connected firmly between first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3,
Promoting the intensity of triangle alloy cutter head, first described cutting blade the 1, second cutting blade 2 and the junction of the 3rd cutting blade 3 are provided with circular arc mistake
Crossing angle 6, the radius at this transition angle 6 is 2 °～5 °；By the connection between first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3
It is 2 °～5 ° of transition angles 6 that place arranges radius, preferably 2 °, so can effectively ensure that first cutting blade the 1, second cutting blade 2 and the 3rd is cut
Bonding strength between sword 3, is prevented effectively from the first cutting blade the 1, second cutting blade 2 and fracture of the 3rd cutting blade 3, extends it and uses the longevity
Life.
In the present embodiment, owing to the cross section of first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3 is arc, the most relative
Make the end angle of cutting blade the most sharp-pointed, in order to prevent cutting blade from collapsing angle, first described cutting blade the 1, second cutting blade 2 and
Three cutting blades 3 and end are respectively equipped with entrance angle 7, and the width of this entrance angle 7 is the first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3
2/5ths of width and its angle be 13 ° ± 2 °；By setting in the end of first cutting blade the 1, second cutting blade 2 and the 3rd cutting blade 3
Putting entrance angle 7, its width is 2/5ths of cutting blade width, and angle is 13 ° ± 2 °, reduce the most accordingly the first cutting blade 1,
Second cutting blade 2 and the sharpness of the 3rd cutting blade 3 entrance angle 7, when carrying out cutting operation, so that it may effectively prevent the first cutting blade 1,
Two cutting blades 2 and the 3rd cutting blade 3 collapse angle, thus can effectively extend the service life of triangle alloy cutter head and making of operator
Use safety.
Above-described embodiment is not construed as limitation of the present invention, but any spiritual improvements introduced based on the present invention, all
Should be within protection scope of the present invention.
