Abstract
The utility model discloses a hard alloy milling cutter which comprises a cutter handle and a cutter body, wherein a cooling liquid through hole is formed in the inner part of the milling cutter; four groups of chip removing grooves and four groups of cutting edges are arranged in the cutter body; an opening is formed in the end edge of the cutting edge on the cutter body; only symmetrical ends of one group, at the cutting edge, of the cutter body are mutually connected. According to the hard alloy milling cutter, the heat dissipation effect of the milling cutter is improved, the cooling liquid is effectively utilized, the working efficiency of the milling cutter is improved and the service life of the milling cutter is prolonged.
Description
Technical field
The utility model relates to a kind of machining equipment, is specifically related to a kind of carbide-tipped milling cutter.
Background technology
Milling cutter is for Milling Process, has the rotary cutter of one or more cutters tooth.When work, individual cutter tooth can be successively intermittently remove cut part, milling cutter is mainly used in processing step on milling machine, plane, groove, molded surface and cut-out workpiece etc., when carbide-tipped milling cutter is used for rough milling, for the processing of large-scale alloy forged piece and sales volume large, because usually cooling mode is difficult for cutter head to lower the temperature, make cutting speed etc. less than good lifting, affect working (machining) efficiency, also can cause and write unnecessary waste, the cutter tooth end of milling cutter does not have chip area, in the easy adhesion of cutter tooth end sword, the wearing and tearing of aggravation cutter, affect the cutting power of milling cutter, reduce milling cutter service life.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, and a kind of carbide-tipped milling cutter is provided, and has cooling block, prevents the advantage of chip removal adhesion.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of carbide-tipped milling cutter, comprises handle of a knife and cutter hub, and milling cutter inside is provided with cooling fluid through hole, and described cutter hub is provided with four groups of chip areas and four groups of blades, and described cutter hub is provided with opening at the end sword place of blade.
Described cooling fluid through hole, comprise the straight way through hole of told handle of a knife internal helicoid through hole and described cutter hub inside, increase the contact area of cooling fluid and milling cutter inside by spiral through hole, accelerate heat radiation, described straight way through hole can effectively prevent from destroying the structure of cutter hub, and is cutter hub heat radiation.
Described cutter hub only has one group of symmetrical end to interconnect at end sword place, prevent that produced scrap from entering into straight way through hole, and scrap is with respect to the milling cutter of holding sword all to link together, can effectively scrap be discharged.
Described blade and described chip area are all helical arrangement, and described helical angle is 30 °～60 °.
The degree of roughness of described blade, handle of a knife is 0.2um, and the roughness of described chip area is 0.4um, and described cutter hub adopts carbide alloy.
The beneficial effects of the utility model: by cooling through hole, temperature while effectively reducing cutter hub corase grind, and cooling fluid flows to cutter hub outside and also can continue as cutter hub outer surface cooling effect is provided, end sword place only has one group of symmetrical end to interconnect, accelerate chip removal speed, the utility model has extended milling cutter service life, has improved milling cutter operating efficiency.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cutaway view;
Fig. 3 is the new right view of this practicality.
In figure, description of reference numerals is as follows: 1, handle of a knife; 2, cutter hub; 3, blade; 4, chip area; 5, opening; 6, cooling fluid through hole; 7, straight way through hole; 8, spiral through hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of carbide-tipped milling cutter, comprises handle of a knife 1 and cutter hub 2, and milling cutter inside is provided with cooling fluid through hole 6, and cutter hub 2 is provided with four groups of chip areas 4 and four groups of blades 3, and cutter hub 2 is provided with opening 5 at the end sword place of blade 3.
Cooling fluid through hole 6, comprise the straight way through hole 7 of told handle of a knife 1 internal helicoid through hole 8 and cutter hub 2 inside, increase the contact area of cooling fluid and milling cutter inside by spiral through hole 8, accelerate heat radiation, straight way through hole 7 can effectively prevent from destroying the structure of cutter hub 2, and dispels the heat for cutter hub 2.
The degree of roughness of blade 3, handle of a knife 1 is 0.2um, and the roughness of chip area 4 is 0.4um, and cutter hub 2 adopts carbide alloy.
In the time that milling cutter of the present utility model is used for roughly grinding, cooling fluid is first by spiral through hole 8, then enter straight way through hole 7, then flow out from opening 5, the cooling fluid of outflow acts on milling cutter outer surface, continue as milling cutter heat radiation, milling cutter is played to cooling effect, and cutter hub 2 has one group of symmetrical end to interconnect at end sword place, prevented that chip from entering straight way through hole 7 and causing obstruction, cutter hub 2 has one group of symmetrical end not interconnect at end sword place, can effectively discharge chip.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technology people of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of 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.
