Description
Technical field
The utility model is related to special milling cutter field more particularly to a kind of left-and-right spiral profile milling cutters.
Background technology
Milling cutter is the rotary cutter for Milling Process, with one or more cutters tooth.When work each cutter tooth successively between
Cut the surplus of workpiece with having a rest.Milling cutter is mainly used for processing plane, step, groove, forming surface and cut-out workpiece on milling machine
Deng.Milling cutter is generally the workpiece for processing specific shape and specially manufactures and designs, and is commonly used for machining angle face, groove surface, spy
Different shape hole and step surface etc., the blade type that milling cutter cuts cutting edge is generally adapted with the shape of workpiece, in order to pass through time processing
Required specific shape is formed on workpiece.To be processed respectively to product with two cutters in the past, need to knife several times and
Tool changing is processed the several positions of product respectively, and this processing efficiency is relatively low.
Utility model content
In order to overcome the defects of the prior art, a kind of left-and-right spiral profile milling cutter is provided.
The utility model is realized by following proposal：
A kind of left-and-right spiral profile milling cutter, includes the handle of a knife of cylindrical-shaped structure, cutter head, and the cutter head includes front end with after
End, be correspondingly provided on the front end it is left right-hand screw cutting edge, in the rear end on be correspondingly provided with it is opposite with nose-cut-ting edge
It is right left-hand screw cutting edge.
Preferably, the size of the core diameter of the front end is the 50% of sword diameter, and the size of the core diameter of the rear end is sword diameter
35%.
Preferably, the front end, rear end spiral cutting sword include three or more cutting tooths, front-end and back-end are cut
Tooth is cut to be spaced apart with same phase difference around the handle of a knife axis.
Preferably, the spiral cutting sword of the front end, rear end is including four cutting tooths.
Preferably, the spiral cutting angle of cutting edge of the front end is 5-7 °, and helical angle is 35 °.
Preferably, the anterior angle of the spiral cutting sword of the rear end is 10-12 °, and helical angle is 35 °.
The first relief angle of corresponding spiral cutting sword is 10 ° -12 ° on the rear end, and the second relief angle is 25 ° ± 2 °.
Preferably, the roughness of the rake face of the spiral cutting sword of the front-end and back-end is no more than 0.2 micron.
The beneficial effects of the utility model are：
To portioned product in machining be related to the more clampings of multi-process need it is several tool sharpening, with the milling cutter of the application
Disposable one cutter can be completed, improve the precision of product, the stability of production, improve production efficiency.

Specific implementation mode
The utility model is further illustrated in the following with reference to the drawings and specific embodiments：
The utility model discloses the handle of a knife 1 of a kind of left-and-right spiral profile milling cutter, including cylindrical-shaped structure, cutter head 2 is described
Cutter head 2 include front end 201 and rear end 202, be correspondingly provided on the front end 201 it is left right-hand screw cutting edge 2011, in the rear
Be correspondingly provided on end 202 it is opposite with nose-cut-ting edge it is right left-hand screw cutting edge 2021.The spiral of front and rear end cutting edge is revolved
To on the contrary, in the present embodiment, the cutting edge of 201 left-hand screw of front end fluting, rear end 202 is the cutting edge of right-hand screw fluting.
It is preferable over, the core diameter r of the front end 2011Size be sword diameter R 50%, the core diameter r of the rear end 2022Ruler
The very little R35% for sword diameter.Its front and back core diameter is different, ensure that cutter rigidity, while effectively preventing grinding manufacture craft mistake
To the influence of cutting edge quality in journey, while avoiding interference with can held stationary in the cutting process, under front end after chip removal
Chip removal is non-interference on end, and bits slag will not scratch machined product face.
Be preferable over, the front end 201, rear end 202 spiral cutting sword include three or more cutting tooths, front end and after
The cutting tooth at end is spaced apart around the handle of a knife axis with same phase difference.
In the present embodiment, the front end 201, rear end 202 spiral cutting sword include four cutting tooths.Front and back end is with circle
Centered on bar axis, four teeth are uniformly distributed, can guarantee high-revolving dynamic balancing, four dental transition are resistance in processing stainless steel material
Mill.
The anterior angle a of the spiral cutting sword of the front end 2011It is 5-7 °, helical angle b1It is 35 °.
The anterior angle a of the spiral cutting sword of the rear end 2022It is 10-12 °, helical angle b2It is 35 °.
First relief angle c of corresponding spiral cutting sword on the rear end 2021、c3、c5It is 10 ° -12 °, the second relief angle c2、c4、
c6It is 25 ° ± 2 °.
The roughness of the rake face of the spiral cutting sword of the front end 201 and rear end 202 is no more than 0.2 micron, reduces
The friction of cutter and machined material in processing, bits slag can quickly be discharged along rake face, keep cutting more brisk, reduce built-up edge
Generation and cutting region temperature it is excessively high, ensure that cutting-tool's used life.
To portioned product in machining be related to the more clampings of multi-process need it is several tool sharpening, with the milling cutter of the application
Disposable one cutter can be completed, workpiece 3 as shown in Figure 3 can be used the milling cutter time processing of this case, improve product
Precision, the stability of production, be not necessarily to multiple clamping, improve production efficiency.
Although having done more detailed elaboration to the technical solution of the utility model and having enumerated, it should be understood that for
For those skilled in the art, modification is made to above-described embodiment or uses equivalent alternative solution, this skill to this field
Be for art personnel it is clear that on the basis of without departing from the spirit of the present invention these modifications or improvements, belong to
In the range of the requires of the utility model protection.
