Figure；
Fig. 2 is the structural representation of cutter head shown in FIG. 1.
Fig. 3 is a kind of part-structure schematic diagram remained in burr when the profile milling cutter on tailing uses shown in Fig. 1.
In figure：Knife bar 1, cutter head 2, cutting edge 3, product 4, connecting rod 11, transition part 12, ramp 31, lower inclined plane 32.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 schematically shows that a kind of of a kind of embodiment according to the present utility model remains in burr on tailing
Profile milling cutter, Fig. 2 then shows the structure of the cutter head 2 for the milling cutter.As shown in Figs. 1-2, which includes one cylindric
Knife bar 1, the diameter of knife bar 1 is generally taken as 4.0mm, and wherein error range can be taken as -0.01~0mm；
And one end end of knife bar 1 is connected with one end of a connecting rod 11, connecting rod 11 is generally also set as cylindric, if its
Length is 2.50mm, and a diameter of 0.8mm, wherein error range can be taken as -0.01~0.01mm.
And in the installation of the other end of connecting rod 11, there are one cutter heads 2, and the entire length of cutter head 2 is 0.40mm, maximum gauge
For 0.16mm, wherein error range is taken as -0.01~0mm；And the entire length of milling cutter is preferably taken as 50.0mm, the company of removing
The length of the length and cutter head 2 of bar 11, the length that can obtain knife bar 1 are 47.1mm.
Further, since the diameter of knife bar 1 and connecting rod 11 is inconsistent, junction that can also be with connecting rod 11 on knife bar 1 is set
One transition part 12, wherein transition part 12 are gradually reduced in cone, diameter from knife bar direction to connecting rod direction, and cone angle is excellent
It is selected as 90 °.
Cutter head 2 is equipped with multiple spiral helicine cutting edges 3 extended outward, and the quantity of cutting edge 3 is generally four,
Even to be distributed on cutter head 2, it is 8 ° that the Angular Dimension of wherein cutting edge 3, which is anterior angle, and relief angle is 8 °, and helical angle is then -20 °.
The side of the cutting edge 3 of general milling cutter is set as inclined-plane, can be used for being processed.And in the present invention, it will
The inclined-plane of the side of the opposite cutting edge 3 in two positions is formed by the oblique angle that angle is known as the inclined-plane of the cutting edge 3.And in this reality
In novel, the side of each cutting edge 3 includes then a ramp 31 and a lower inclined plane 32, and wherein lower inclined plane 32 is compared on
Inclined-plane 31 is far from knife bar 1.
The length of lower inclined plane 32 is preferably set to 0.15mm, and wherein its error range is -0.02~0mm.And due to cutter head 2
Entire length be 0.40mm, wherein error range can be taken as -0.01~0mm, it is known that the length of ramp 31 be 0.25mm.
And the angle at the oblique angle of ramp 31 is preferably taken as 8.6 °, the angle at the oblique angle of lower inclined plane 32 can be taken as 77.3 °, much larger than upper
The angle at the oblique angle on inclined-plane 31, it follows that the width of lower inclined plane 32 is smaller than ramp 31.
General milling cutter is in processing, after the cutting edge on cutter head is extend into the working position of product, due to cutting
The side of sword is provided only with an inclined-plane, and generated burr can be left on product by the compressing of cutting edge, then also need
Manually burr to be removed, it is time-consuming and laborious, it is also possible to influence product quality.
Fig. 3 is the structure of milling cutter its 2 part of cutter head when in use shown in Fig. 1.As shown in figure 3, using the utility model
In milling cutter when being processed to product 4, the cutting edge 3 on cutter head 2 can extend into the working position of product 4, the utility model
In milling cutter there are two the different inclined-planes of angle, and since the angle at the oblique angle of lower inclined plane 32 is larger so that its width is than upper
Inclined-plane 31 is small, and thus lower inclined plane 32 can form a dead zone that can temporarily accommodate tailing in processing with 4 inner wall of product, and
The burr generated when processing can be fallen on the tailing to fall off in the dead zone, and be stayed in tailing by the compressing of cutting edge 3
On, it can be also discharged after processing is completed with tailing, not only need not manually remove deburring, it is ensured that the matter of product 4
Amount, additionally it is possible to reduce tool wear, improves cutter life.
In addition, the top on the working position of product 4 is in the lower inclined plane 32 of the position of connecting rod 11 and lower section and product 4
The dead zone distance that wall is formed farther out, so burr and tailing caused by being processed at the position are difficult to fall in dead zone sometimes,
To be left on product 4 by the compressing of ramp 31.At this point it is possible to which designing makes cutter head 2 at the interconnection with connecting rod 11
It being slightly slanted to connecting rod 11, angle of inclination is preferably 2 ° or so, in this way, in processing, the top on the working position of product 4
Burr and tailing caused by the position of close connecting rod 11 can be detached from along the top of cutter head 2 from working position, so as to
It is enough smoothly to remove deburring, while ensure that the quality of product 4.
It follows that knife in the present invention is larger and wide by the way that an oblique angle is arranged in the end profile of cutting edge
The smaller lower inclined plane of degree, makes it form one dead zone with product inner wall, and generated burr is with falling off when to make processing
Tailing fall in the dead zone and stayed on tailing together, then can be easily discharged with tailing.On the one hand, it ensure that production
Quality improves product yield；On the other hand, reduce to the degree of wear, improve service life and the equipment of cutter
Utilization rate；In addition, also saving manpower and materials, processing cost is reduced.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
