Description
Technical field
The present invention relates to a kind of brills to mill composite cutter.
Background technique
Slot position, the hole location of several installations are offered on handset shell, the edge of handset shell is equipped with radian or gradient is different
Bevel edge, specifically depending on the Cell Phone Design of different model depending on, to those installation positions and its corresponding bevel edge carry out molding add
When work, it usually needs multiple cutter cooperations carry out：It is first drilled or is slotted by bore cutter, then by not having to radian or gradient
Angle cutting tool carry out milling side.Cutter be easy to cause the handset shell process tool of different model chaotic more when processing, while
Increase the cost of cutter.
Summary of the invention
In order to overcome the deficiencies of the prior art, the present invention proposes a kind of brill milling composite cutter, drills compound with the rose reamer on milling side,
The accuracy and matching degree for improving processing simultaneously are avoided using confusion, also reduction production cost.
The present invention proposes that a kind of brill milling composite cutter, including cutter head and knife bar, the cutter head include two cutting edge portion and be located at
Chip space between two cutting edge portion, the cutting edge portion successively include drilling section, chamfering section and segment of cutting, the drilling section packet
Include drilling sword and the first cutting edge, the drilling sword is set to the end of the cutter head, and the chamfering section includes the first chamfering blades, the
Two chamfering blades, and the changeover portion of connection the first chamfering blades and the second chamfering blades, the segment of cutting include the second cutting edge.
It further, is in inner concavity in cutting edge portion described in the chamfering Duan Yu.
Further, first chamfering blades are arc sword.
Further, second chamfering blades are straight sword.
Further, it is in twisted shape that the cutting edge portion is twisted tilted.
Further, first cutting edge is connected with major first face, the first main flank and minor first flank, institute
It states the second cutting edge and is connected with the second rake face, the second main flank and the second minor flank, the major first face and second
Rake face, minor first flank and the second minor flank are separately connected into the cell wall of chip space.
Further, the cutter head is set on tool apron, and is connect by the tool apron with knife bar, and the chip space extends to institute
It states on tool apron.
The beneficial effects of the present invention are：Cutting edge portion of the invention successively includes drilling section, chamfering section and segment of cutting, is led to
Cross and be embedded in double rose reamers on bore cutter, realize that drilling and the rose reamer on milling side are compound, at the same improve processing accuracy and
With degree, avoid reducing production cost using confusion.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of side of the present invention.
Fig. 3 is the structural schematic diagram of cutter head end face of the invention.
Specific embodiment
As follows in conjunction with attached drawing, application scheme is further described：
Referring to attached drawing 1-3, a kind of brill mills composite cutter, including cutter head 2 and knife bar 1, the cutter head 2 include two cutting edge portion and
Chip space 3 between two cutting edge portion, the twisted tilted cutting edge portion is in twisted shape.The cutter head 2 is set to tool apron 21
On, and connect by the tool apron 21 with knife bar 1, the chip space 3 extends on the tool apron 21.
The cutting edge portion successively includes drilling section a, chamfering section b and segment of cutting c.The chamfering section b is in the cutting edge
It is in inner concavity in portion.The drilling section a includes drilling sword 5 and the first cutting edge 6, and the drilling sword 5 is set to the end of the cutter head 2
Portion.The chamfering section b includes the first chamfering blades 7,8 sword of the second chamfering, and the first chamfering blades 7 of connection and the second chamfering blades 8
Changeover portion 9, the design of changeover portion 9 avoid the first chamfering blades 7 and the second chamfering blades 8 from crossing and cusp occur.First chamfering blades 7
For arc sword；Second chamfering blades 8 are straight sword.The segment of cutting c includes the second cutting edge 4.The drilling section a and segment of cutting c
Drilling cutting is carried out as bore cutter, the chamfering section b carries out milling molding for opponent's envelope edge.Milling edge formation packet
Include the molding arc side of the first chamfering blades 7 and the molding straight flange of the second chamfering blades 8.
First cutting edge 6 is connected with major first face 61, the first main flank 62 and minor first flank 63, described
Second cutting edge 4 is connected with the second rake face 41, the second main flank 42 and the second minor flank 43, the major first face 61
The cell wall of chip space 3 is separately connected into the second rake face 41, minor first flank 63 and the second minor flank 43, large area
Chip space helps with chip and cuts the discharge of heat, reduces tool wear.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Same, approximate or technology deduction, replacement, improvement for making based on this etc., are regarded as the protection scope of this patent.
