Description
Technical field
The utility model relates to a kind of milling cutter, especially a kind of multiple-grooved is integrally formed milling cutter.
Background technique
It needs to process the step of four different heights on the outer housing of apple camera, is used as capillary groove, card slot etc.,
Good airproof performance is sought, was repeatedly processed using multitool in the past, to need repeatedly dress knife multiple bearing, causes precision not high, thus this
Applicant, which devises a kind of multiple-grooved and is integrally formed milling cutter, to be processed and formed at one time, and not only process time is short, high-efficient, to be processed into
This is also low.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of multiple-grooved integrated molding milling cutter.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of multiple-grooved is integrally formed milling cutter, including knife bar, it is characterised in that: the end of the knife bar is equipped with chip space, the
One cutting seat, the second cutting seat, third cut seat, and the chip space, the first cutting seat, the second cutting seat, third cutting seat are equal
It being bent in the shape of a spiral, and the first cutting seat is equipped with upper cutting edge portion, the second cutting seat is equipped with middle cutting edge portion,
The third cutting seat is equipped with lower cutting edge portion, and the upper cutting edge portion, middle cutting edge portion, lower cutting edge portion are apart from knife bar
The height of end face is different, and the upper cutting edge portion includes flank on first, flank and corresponding chip removal on described first
The side wall intersection of slot constitutes upper cutting edge；The middle cutting edge portion includes flank in first, flank and phase in described first
The side wall of chip space is answered to intersect cutting edge in composition；The lower cutting edge portion includes the first lower flank, the described first lower rear knife
Face is intersected with the side wall of corresponding chip space constitutes lower cutting edge, and the shape of the upper cutting edge is a straight line and the center with knife bar
Axis is parallel, and the shape of the middle cutting edge is V-shaped, and the shape of the lower cutting edge is arc.
The upper cutting edge portion further includes flank on second；The middle cutting edge portion further includes flank in second；Institute
Stating lower cutting edge portion further includes the second lower flank.
The beneficial effects of the utility model are: the end of the knife bar of the utility model is equipped with chip space, the first cutting seat, the
Two cutting seats, third cut seat, and it is described first cutting seat be equipped with upper cutting edge portion, it is described second cutting seat be equipped in cut
Cut blade, the third cutting seat is equipped with lower cutting edge portion, the upper cutting edge portion, middle cutting edge portion, lower cutting edge portion away from
Height from the end face of knife bar is different, thus time processing, can the upper processing on outer housing by above-mentioned cutting edge portion
The slot of three different sizes out does not have to tool changing and positioning, thus processing technology difficulty is low, high-efficient, cost is also low.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the front view of the utility model；
Fig. 3 is the enlarged view of the cutter head of the utility model.
Specific embodiment
Referring to figs. 1 to Fig. 3, the utility model discloses a kind of multiple-grooveds to be integrally formed milling cutter, including knife bar 1, the knife bar 1
End be equipped with chip space 2, first cut seat 3, second cut seat 4, third cut seat 5, first cutting seat 3, second cut seat
4, third cutting seat 5 is arranged in pairs, and successively between time arrangement, the chip space 2, first cuts seat 3, second and cuts seat 4, the
Three cutting seats 5 are bent in the shape of a spiral, guarantee the high speed of Cutting Stiffness and chip removal, and the first cutting seat 3 is equipped with upper
Cutting edge portion 31, the second cutting seat 4 are equipped with middle cutting edge portion 41, and the third cutting seat 5 is equipped with lower cutting edge portion
51, the upper cutting edge portion 31, the height of the end face of middle cutting edge portion 41, lower cutting edge portion 51 apart from knife bar 1 are different, from
And slot is milled out at various height, the upper cutting edge portion 31 includes flank 32 on first, flank 32 on described first
Intersect with the side wall of corresponding chip space 2 and constitutes upper cutting edge 33；The middle cutting edge portion 41 includes flank 42 in first, described
Flank 42 intersects cutting edge 43 in composition with the side wall of corresponding chip space 2 in first；The lower cutting edge portion 51 includes first
Lower flank 52, the described first lower flank 52 intersects with the side wall of corresponding chip space 2 constitutes lower cutting edge 53, the upper cutting
The shape of sword 33 is a straight line and the centerline axis parallel with knife bar 1, thus upper cutting edge 33 mills out square groove, the middle cutting edge
43 shape is V-shaped, thus upper cutting edge 33 washes out V-shaped groove, and the shape of the lower cutting edge 53 is arc, can be milled in this way
The cambered surface being recessed out.
As shown, the upper cutting edge 33 31 further include flank 34 on second；The middle cutting edge 43 41 also
Including flank 44 in second；The lower cutting edge 53 51 further include the second lower flank 54.
Milling cutter is integrally formed to a kind of multiple-grooved provided by the utility model embodiment above, is described in detail, this
It applies specific case in text to be expounded the principles of the present invention and embodiment, the explanation of above embodiments is
It is used to help understand the method and its core concept of the utility model；At the same time, for those skilled in the art, according to this
The thought of utility model, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification
It should not be construed as a limitation of the present invention.
