The applicant devises a double-sided lateral milling forming cutter to solve the above problems.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of double-sided lateral milling forming cutter.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of double-sided lateral milling forming cutter, including knife bar and cutter head, it is characterised in that：The cutter head is equipped with several combinations and cuts
Blade is cut, which includes front arc milling cutting portion, straight milling cutting portion and the rear arc milling cutting portion of sequence setting,
The front arc milling cutting parts are equipped with the chip space for extending to knife bar, the chip space in the end of cutter head, the cutter head
Between two combination cutting edge portion, the straight milling cutting portion includes straight cutting edge, straight milling rake face and straight milling flank, described straight
Cutting edge is that straight milling flank and straight milling rake face are crossed to form, and the front arc milling cutting portion includes front arc cutting edge, preceding
Arc milling rake face and front arc milling flank, the front arc cutting edge are front arc milling flank and front arc milling rake face
It is crossed to form；The rear arc milling cutting portion includes rear arc cutting edge, rear arc milling rake face and rear arc milling flank, institute
It is that rear arc milling flank and rear arc milling rake face are crossed to form to state rear arc cutting edge, the front arc cutting edge, vertical cut
Cut sword intersect with rear arc cutting edge constitute a continuous smooth lines, the front arc milling rake face, straight milling rake face after
Arc milling rake face is that the edge portions of chip removal groove sidewall are constituted.
The front arc milling flank includes preceding first arc milling flank and preceding second arc milling flank；The backarc
Shape milling flank includes rear first arc milling flank and rear second arc milling flank.
The straight milling flank includes the first straight milling flank and the second straight milling flank.
The chip space is helicla flute.
The shape of the front arc cutting edge and rear arc cutting edge is made of the continuous camber line of multistage.
The beneficial effects of the invention are as follows：The cutter head of the present invention is equipped with several combination cutting edge portion, the combination cutting edge portion
Include front arc milling cutting portion, straight milling cutting portion and the rear arc milling cutting portion of sequence setting, the front arc milling cutting parts
In the end of cutter head, cutter is parallel with the phone housing back side when processing mobile phone shell, passes through the vertical cut of straight milling cutting portion
While cutting sword processing mobile phone shell rear surface, by the front arc cutting edge of front arc milling cutting portion to the one side of phone housing
It is processed；The another side of phone housing is processed by the rear arc cutting edge by rear arc milling cutting portion, from
And can be once by the back side of phone housing and side while completion of processing, the above process does not have to tool changing, thus not only saves
Tool change time improves that efficiency and precision are more preferable, processing cost is lower.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the topology view of the present invention.
Specific implementation mode
Referring to Fig.1, include circular knife bar 1 and cutter head 2, the cutter head the invention discloses a kind of double-sided lateral milling forming cutter
It is set on 2 there are four cutting edge portion is combined, which includes the front arc milling cutting portion of sequence setting, straight milling cutting portion
And rear arc milling cutting portion, the front arc milling cutting parts are equipped in the end of cutter head, the cutter head and extend to knife bar
Chip space 3, the chip space 3 are located between two combination cutting edge portion, and the straight milling cutting portion includes knife before straight cutting edge 4, straight milling
Face and straight milling flank, the straight cutting edge 4 are that straight milling flank and straight milling rake face are crossed to form, and the front arc milling is cut
Portion includes front arc cutting edge 5, front arc milling rake face and front arc milling flank, and the front arc cutting edge 5 is front arc
Milling flank and front arc milling rake face are crossed to form；The rear arc milling cutting portion includes rear arc cutting edge 6, rear arc milling
Rake face and rear arc milling flank, the rear arc cutting edge 6 are that rear arc milling flank and rear arc milling rake face intersect
It is formed, the front arc cutting edge 5, straight cutting edge 4 intersect with rear arc cutting edge 6 constitutes a continuous smooth lines, described
Front arc milling rake face, the equal rear arc milling rake face of straight milling rake face are that the edge portions of 3 side wall of chip space are constituted.
As shown, straight cutting edge 4 be a helix, but the sword diameter of the every bit on the helix be it is identical, thus
Machinable goes out plane, and the shape of the front arc cutting edge 5 and rear arc cutting edge 6 is made of the continuous camber line of multistage,
The variation of sword diameter is changed by the variation of camber line, because the arc of phone housing side may be the different cambered surface of multiple radians
Constitute, thus the shape of front arc cutting edge 5 and rear arc cutting edge 6 also need to by multistage continuously with the contour line phase of cambered surface
The camber line matched is constituted, to be the side processing of phone housing.
As shown, the front arc milling flank includes knife after preceding first arc milling flank 7 and preceding second arc milling
Face 8；The rear arc milling flank includes rear first arc milling flank 9 and rear second arc milling flank 10；The straight milling
Flank includes 11 and second straight milling flank 12 of the first straight milling flank；In above structure, the design of continuous multiple flanks
Low-angle relief angle is gently favorably dropped to from the relief angle of wide-angle, not only can guarantee that cutter head 2 has enough intensity, but also can reduce and cut
The friction between sword and machined surface is cut, prevents from generating heat, to effectively in raising cutting precision.
The chip space 3 is helicla flute, and spiral helicine chip space 3 not only holds that bits amount is big, but also the process rotated in cutter
In, iron filings are larger by the extruding force of 3 wall of chip space, so as to quickly iron filings be guided to be discharged.
It is provided for the embodiments of the invention a kind of double-sided lateral milling forming cutter above, is described in detail, answers herein
With specific case, principle and implementation of the present invention are described, and the explanation of above example is only intended to help to manage
Solve the method and its core concept of the present invention；Meanwhile for those of ordinary skill in the art, according to the thought of the present invention,
There will be changes in specific implementation mode and application range, in conclusion the content of the present specification should not be construed as to this hair
Bright limitation.
