Description
Technical field
The present invention relates to a kind of cutter, particularly a kind of watchcase inwall forming cutter.
Background technology
Wrist-watch is the conventional carry-on articles of present social people, and the general precision prescribed of wrist-watch is higher, particularly mechanical watch,
Pointer fine rotational is all made by mechanical engagement, thus it is higher to required precision, and if to ensure service precision, we are first
First require that machining accuracy reaches requirement, so as to which the applicant devises a forming cutter to process wrist-watch inner casing, ensure processing essence
Degree.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of watchcase inwall forming cutter.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of watchcase inwall forming cutter, including cutter head and knife bar, it is characterised in that：The cutter head end face is provided with combination forming blade
And chip area, the combination forming blade include knife face after rake face, combination, and rake face intersects the group formed with knife face after combination
Cutting edge is closed, the rake face is formed for the one side of chip area, the first perpendicular sword that the combination cutting edge includes being sequentially connected,
First chisel edge, the first Circular Nose Cutting Edge, the second chisel edge.
Described first perpendicular sword is vertical with the first chisel edge.
The chip area is V-groove, and the cutter head is provided with an inclined-plane, and the inclined-plane intersects with the side described in composition
Chip area.
Knife face includes knife face, second after knife face, the first Circular Nose Cutting Edge after knife face, the first chisel edge after the first perpendicular sword after the combination
Knife face after chisel edge, the described first perpendicular sword is intersected by knife face after the first perpendicular sword with rake face to be formed, and first chisel edge is horizontal by first
Knife face intersects composition with rake face after sword, and first Circular Nose Cutting Edge is intersected by knife face after the first Circular Nose Cutting Edge with rake face to be formed, institute
State the second chisel edge and intersected by knife face after the second chisel edge with rake face and formed.
The beneficial effects of the invention are as follows：Bag cutter head and knife bar of the present invention, the cutter head end face be provided with combination forming blade and
Chip area, the combination forming blade include knife face after rake face, combination, and rake face intersects the combination formed with knife face after combination
Cutting edge, the rake face are formed for the one side of chip area, the first perpendicular sword that the combination cutting edge includes being sequentially connected, the
One chisel edge, the first Circular Nose Cutting Edge, the second chisel edge.
The present invention is provided with combination forming blade and chip area including cutter head end face, and the combination forming blade includes rake face, combination
Knife face afterwards, and rake face intersect the combination cutting edge formed with knife face after combination, and the rake face is the one side structure of chip area
Into the combination cutting edge is made up of some sections of straight lines, and said structure can not only complete wrist-watch inner casing processing and forming, and group
Synthesis type blade intensity is high, is not easy to crumble, chip resistance is good.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the present invention；
Fig. 2 is the view of the other direction of the present invention.
Embodiment
Reference picture 1, Fig. 2, the invention discloses a kind of watchcase inwall forming cutter, including cutter head 1 and knife bar 2, the cutter head 1
End face is provided with combination forming blade and chip area 3, and the combination forming blade includes knife face after rake face 4, combination, and rake face 4
Intersect the combination cutting edge formed with knife face after combination, the rake face 4 is formed for the one side of chip area 3, and the combination is cut
Cut the first perpendicular sword 5, the first chisel edge 6, the first Circular Nose Cutting Edge 7, the second chisel edge 8 that sword includes being sequentially connected.
Described first perpendicular sword 5 is vertical with the first chisel edge 6.
The chip area 3 is V-groove, and the cutter head 1 is provided with an inclined-plane, and the inclined-plane intersects with the side forms institute
Chip area 3 is stated, because this structure is cutting edge combination cutting, the position height of each cutting edge is again different, thus in order to ensure
The intensity and function of cutting edge, V-groove is preferably provided to, and V-groove empty avoiding space is big.
After the combination knife face include after the first perpendicular sword after knife face 9, the first chisel edge knife face after knife face 10, the first Circular Nose Cutting Edge,
Knife face after second chisel edge, the described first perpendicular sword 5 is intersected by knife face 9 after the first perpendicular sword with rake face 4 to be formed, first chisel edge 6
Intersected by knife face 10 after the first chisel edge with rake face 4 and formed, first Circular Nose Cutting Edge 7 is by knife face and rake face after the first Circular Nose Cutting Edge
4 intersecting compositions, second chisel edge 8 is intersected by knife face after the second chisel edge with rake face 4 to be formed.
A kind of watchcase inwall forming cutter provided above the embodiment of the present invention, is described in detail, and herein should
The principle and embodiment of the present invention are set forth with specific case, the explanation of above example is only intended to help and managed
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 embodiment and application, in summary, this specification content should not be construed as to this hair
Bright limitation.
