Abstract
The utility model discloses a kind of single side side milling forming cutters, cutter head is equipped with several combination cutting edge portion, the combination cutting edge portion includes straight milling cutting portion and arc milling cutting portion, the straight milling cutting parts are in one end away from knife bar, it thus can be with cutter installation parallel with the phone housing back side when processing mobile phone shell, while by the straight cutting edge processing mobile phone shell rear surface of straight milling cutting portion, the arc milling sword of arc milling cutting portion is also processed the side of phone housing, the above process does not have to tool changing, thus not only save tool change time, improve efficiency, and precision is more preferable, processing cost is lower.
Description
Technical field
The utility model is related to a kind of cutters, particularly a kind of single side side milling forming cutter.
Background technology
The side of phone housing is usually all designed to smooth arc shape for beauty, and the back side of phone housing is then
It is smooth flat, thus after phone housing shaping the surface that its side and the back side are processed into best bright finish is needed to need with two
Different milling cutters is processed, aforesaid way needs tool changing, and not only long processing time, efficiency are low, but also high processing costs.Thus
The applicant devises a single side side milling forming cutter to solve the above problems.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of single side side milling forming cutter.
Technical solution is used by the utility model solves its technical problem：
A kind of single side side 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 straight milling cutting portion and arc milling cutting portion, and the straight milling cutting parts are in away from knife bar
One end, the cutter head, which is equipped with, extends to the chip space of knife bar, and the chip space is located between two combination cutting edge portion, described straight
Milling cutting portion includes knife face after straight cutting edge and straight milling, and the part edge of the one side wall of the chip space forms straight milling rake face,
The straight cutting edge is that knife face and straight milling rake face are crossed to form after straight milling, the arc milling cutting portion include arc milling sword and
Knife face after arc milling, another part edge of the one side wall of the chip space form arc milling rake face, the arc milling sword
It is crossed to form for knife face after arc milling and arc milling rake face, it is continuous that the straight cutting edge intersects composition one with arc milling sword
Smooth lines.
Knife face includes knife face after knife face after the first straight milling and the second straight milling after the straight milling.
Knife face includes knife face after knife face after the first arc milling and the second arc milling after the arc milling.
The chip space is helicla flute.
The beneficial effects of the utility model are：The cutter head of the utility model is equipped with several combination cutting edge portion, the combination
Cutting edge portion include straight milling cutting portion and arc milling cutting portion, the straight milling cutting parts in away from knife bar one end, thus
It can be processed when processing mobile phone shell with cutter installation parallel with the phone housing back side by the straight cutting edge of straight milling cutting portion
While the phone housing back side, the arc milling sword of arc milling cutting portion is also processed the side of phone housing, above-mentioned mistake
Cheng Buyong tool changing, thus not only save tool change time, improve efficiency and precision is more preferable, processing cost is lower.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the topology view of the utility model.
Specific embodiment
With reference to Fig. 1, the utility model discloses a kind of single side side milling forming cutter, including circular knife bar 1 and cutter head 2, institute
It states and is set on cutter head 2 there are four combination cutting edge portion, which includes straight milling cutting portion and arc milling cutting portion, described
Straight milling cutting parts are equipped with the chip space 3 for extending to knife bar 1, the chip space 3 in one end away from knife bar 1, the cutter head 2
Between two combination cutting edge portion, the straight milling cutting portion includes knife face after straight cutting edge 4 and straight milling, and the one of the chip space 3
The part edge of side wall forms straight milling rake face, and the straight cutting edge 4 is crossed to form for knife face after straight milling and straight milling rake face, institute
Stating arc milling cutting portion includes knife face after arc milling sword 5 and arc milling, another part edge of the one side wall of the chip space 3
Arc milling rake face is formed, the arc milling sword 5 is crossed to form for knife face after arc milling and arc milling rake face, the vertical cut
It cuts sword 4 and intersects one continuous smooth lines of composition with arc milling sword 5.
As shown in the figure, straight cutting edge 4 be a helix, but the sword footpath of the every bit on the helix be it is identical, thus
Machinable goes out plane, is formed because the arc of phone housing side may be the different cambered surface of multiple radians, thus arc milling
The camber line that the shape of sword 5 is also continuously matched by multistage with the contour line of cambered surface is formed, and the variation in sword footpath is by cambered surface
Change and change, so as to be the side processing of phone housing.
As shown in the figure, knife face includes knife face 7 after 6 and second straight milling of knife face after the first straight milling after the straight milling；The arc
Knife face includes knife face 9 after 8 and second arc milling of knife face after the first arc milling after milling.In said structure, continuous multiple rear knife faces
Design favorably gently drops to low-angle relief angle from the relief angle of wide-angle, not only can guarantee that cutter head 2 has enough intensity, but also can reduce
Friction between cutting edge and machined surface prevents from generating heat, so as 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 discharge.
It to a kind of single side side milling forming cutter that the utility model embodiment is provided, is described in detail, herein should
The principle and embodiment of the utility model is set forth with specific case, the explanation of above example is only intended to sides
Assistant solves the method and its core concept of the utility model；It is new according to this practicality meanwhile for those of ordinary skill in the art
The thought of type, there will be changes in specific embodiments and applications, in conclusion this specification content should not manage
It solves as the limitation to the utility model.
