Technical field
The utility model relates to milling cutter technical field, especially relates to a kind of Integral alloy R type balance milling cutter.
Background technology
The notch of existing R type milling cutter is generally straight trough, can waste a large amount of man-hours in the process of processing, and in use procedure, efficiency comparison is low, quick abrasion, and the life-span is short, waste resource, and in being difficult to be applied to and running up.In view of this, one is raised the efficiency, and reduces wear, and having of life-extending novel milling cutter is necessary.
Utility model content
The utility model, for solving the problems of the technologies described above, is to provide a kind of Integral alloy R type to balance milling cutter.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of Integral alloy R type balance milling cutter, comprises shank section and cutter head portion,
Described cutter head portion is provided with multiple blade, and multiple described blade is distributed in the surrounding in described cutter head portion, described blade in described cutter head portion in the shape of a spiral;
Described blade, described cutter head portion and described shank section are formed in one;
The helical angle of described blade in described cutter head portion is 30 ° ~ 40 °.
As preferred technical scheme, the middle part of described blade caves inward, and is respectively equipped with land at two of described blade, and the chamfering of described land is 15 °.
As preferred technical scheme, described blade is provided with multiple chip-breaker.
As preferred technical scheme, described blade is provided with 1-3 chip-breaker, and further, the chip-breaker quantity of spaced described blade is identical.
As preferred technical scheme, described blade is the left sword of dextrorotation in described cutter head portion.
As preferred technical scheme, described shank section is provided with more than one connection draw-in groove, realizes the steadiness installed.
Beneficial effect
The utility model Integral alloy R type balance milling cutter due to blade be helical structure, and helical angle is 30 ° ~ 40 °, increases the area of cut, improves production efficiency, extend service life; Be provided with again blade and ligament, better extend service life, and the effect of use at a high speed can be ensured.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Wherein:
1-R type balance milling cutter, 11-shank section, 12-cutter head portion, 13-connect draw-in groove, 121-blade, 1212-land, 12111-chip-breaker.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Figure 1-Figure 2: Integral alloy R type balance milling cutter 1, is made up of shank section 11 and cutter head portion 12.Wherein cutter head portion 12 is provided with multiple blade 121, blade quantity in the present embodiment is chosen for six, and these six blades 121 are distributed in the surrounding in cutter head portion 12, blade 121 on cutter head 12 in the shape of a spiral, can the area of cut be increased like this, efficiency is significantly improved.Wherein blade 121, cutter head portion 12 are formed in one with shank section 11, and its material is alloy.In order to determine optimized cutting area, arranging the helical angle of blade 121 in cutter head portion 12 is 30 ° ~ 40 °.Helical angle in cutter head portion 12 in the present embodiment is set as 35 °, increases the area of cut, improves service life.In order to increase the service life further, the middle part of blade 121 caves inward; In the present embodiment, blade 121 is the left sword of dextrorotation in cutter head portion 12; Be respectively equipped with land 1212 at two of blade 121, wherein the chamfering of land 1212 is 15 °.Blade 121 is provided with multiple chip-breaker 12111, be traditionally arranged to be 1-3 chip-breaker 12111, and chip-breaker 12111 quantity of spaced blade is identical, namely the quantity of the chip-breaker 12111 of odd number gear is identical, in concrete the present embodiment be three, the quantity of the chip-breaker 12111 of even number tooth is identical, is 2 in concrete the present embodiment.More firm in order to make to install, shank section 11 is provided with more than one connection draw-in groove 13, in the present embodiment is two and connects draw-in groove.Integral alloy R type balance milling cutter in the present embodiment due to blade be helical structure, and helical angle is 30 ° ~ 40 °, increases the area of cut, improves production efficiency, extend service life; Be provided with again blade and ligament, better extend service life.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
