Abstract
The utility model discloses a kind of superhard knife cut off for chip, light guide plate, it is characterised in that：Including superhard knife body and cutting edge, the cutting edge is arranged on superhard knife body, both are structure as a whole, the cutting edge includes symmetric part and non-symmetrical portion, the symmetric part is arranged on superhard knife body upper end, the non-symmetrical portion is arranged on symmetric part upper end, three is structure as a whole, the utility model cutter is according to designing different angle automatchings using product object, symmetry angle and asymmetric angle are designed, prevents chip from chamferring, makes the product cut surface after cutting without scratch, flash, and other defect.
Description
Technical field
The utility model is related to a kind of superhard knife, in particular, and it is related to a kind of for chip（Sheet capacitor/MLCC,
Chip inductor/ferrite inductance, semiconductor chip etc. are commonly called as）The superhard knife of light guide plate extrusion mouth of a river cut-out.
Background technology
Chip industry is increasingly minimized originating from Japan.The precision of chip is directly connected to the efficiency and electricity of SMT attachments
The effect of property.The cutter of cut-out mainly with coarse carbon steel knife or common wolfram steel knife, does not reach the required precision of element.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is that providing a kind of chip, light guide plate of being used for cuts
Disconnected superhard knife.
To achieve the above object, the utility model provides following technical scheme：It is a kind of to be cut off for chip, light guide plate
Superhard knife, it is characterised in that：Including superhard knife body and cutting edge, the cutting edge is arranged on superhard knife body, and both are integrated
Structure, the cutting edge includes symmetric part and non-symmetrical portion, and the symmetric part is arranged on superhard knife body upper end, described non-
Symmetric part is arranged on symmetric part upper end, and three is structure as a whole.
Preferably, non-symmetrical portion includes left side cutting edge and right side cutting edge, the folder of the left side cutting edge and blade tip bisector
Angle is β 1, and β 1 is 2 degree, and the right side cutting edge includes upper cutting edge and lower cutting edge, and the angle of the upper cutting edge and blade tip bisector is β
2, β 2 be 2 degree, and the angle of the lower cutting edge and blade tip bisector is β 5, and β 5 is 8.5 or 9 degree.
Preferably, the angle of symmetric part and superhard knife body side is β 3, β 4, and β 3, β 4 are 8.5 or 9 degree.
Preferably, superhard knife body and cutting edge are the superhard wolfram steel material of ultra micron.
The utility model tool has the advantage that：The utility model cutter is according to designing different angles using product object
Match somebody with somebody, design symmetry angle and asymmetric angle prevent chip from chamferring, make the product cut surface after cutting without scratch, flash, and its
His defect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in reference picture 1, a kind of superhard knife cut off for chip, light guide plate of the present embodiment, including superhard knife body 1
With cutting edge 2, the cutting edge 2 is arranged on superhard knife body 1, and both are structure as a whole, and the cutting edge 2 includes the He of symmetric part 21
Non-symmetrical portion 22, the symmetric part 21 is arranged on the superhard upper end of knife body 1, and the non-symmetrical portion 22 is arranged on symmetrical portion
Divide 21 upper ends, three is structure as a whole.
It is explained for all parts of the present embodiment：
1）Non-symmetrical portion 22 includes left side cutting edge and right side cutting edge, and the angle of the left side cutting edge and blade tip bisector is
β 1, β 1 is 2 degree, and the right side cutting edge includes upper cutting edge and lower cutting edge, and the angle of the upper cutting edge and blade tip bisector is β 2, β 2
For 2 degree, the angle of the lower cutting edge and blade tip bisector is β 5, and β 5 is 8.5 or 9 degree.
2）The angle of symmetric part 21 and the superhard side of knife body 1 is β 3, β 4, and β 3, β 4 are 8.5 or 9 degree.
3）Superhard knife body 1 is the superhard wolfram steel material of ultra micron with cutting edge 2.
The utility model cutter according to designing different angle automatchings using product object, design symmetry angle with it is asymmetric
Angle, prevents chip from chamferring, and makes the product cut surface after cutting without scratch, flash, and other defect.
Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
