Description
Technical field
The present invention relates to machining cutting tool technical field, relate to or rather a kind of blade for gear milling cutter device for milling gear, tooth bar.
Background technology
At present, in mechanical gear processing, traditional processing mode mainly contains two kinds: a kind of is on special gear shapping machine, to carry out shaping; Another kind is on special gear-hobbing machine, to carry out gear hobbing processing.All there is certain manufacturing deficiency in these two kinds of processing modes.Gear Shaping efficiency is low; What cutter material was selected is high-speed steel, and in process, wearing and tearing comparatively fast, not only increase the cost of charp tool, and is difficult to guarantee stable dimensional accuracy, causes the uniformity of the product processing poor.Gear hobbing accurate to dimension is not high, and surface smoothness is not high yet, thereby reduces the quality of workpiece.And two kinds of processing modes need special gear shapping machine and gear-hobbing machine above, make the equipment cost of processing higher.
Summary of the invention
The technical problem to be solved in the present invention is that a kind of blade for gear milling cutter device that is applied to machining gears on milling cutter device, tooth bar is provided.
Technical solution of the present invention is, a kind of blade for gear milling cutter device with following structure is provided, and comprises body; Described body is triangular shaped; On each angle of described body, be equipped with cutter head; The center of described body is provided with installing hole; The shape of the cross section of each cutter head all matches with the shape of the cross section of the teeth groove of processed gear.
Adopt after above structure, the present invention for the blade of gear milling cutter device compared with prior art, has the following advantages:
Because the shape of the cross section of each cutter head of the blade for gear milling cutter device of the present invention all matches with the shape of the cross section of the teeth groove of processed gear, therefore blade of the present invention is arranged on milling cutter device with regard to formative gear milling cutter device, by gear milling cutter application of installation in machining gears, tooth bar, make gear, the processing of tooth bar has the advantage of milling cutter device processing, make working (machining) efficiency higher, accurate to dimension is high, the surface smoothness of the product processing is good, and add man-hour as long as milling cutter device is arranged on the lathe of machining center and just can, without special equipment, thereby can reduce equipment cost.In addition, blade of the present invention has three cutter heads, can change use according to the abrasion condition of cutter head, takes full advantage of material.
As a modification of the present invention, the body described in described body is made by W-Co kind carbide alloy or titanium cobalt series hard alloy or General hard alloy.Adopt after this kind of structure, make the hardness of described blade high, wearability good, heat-resisting quantity is strong, thereby can extend the service life of blade, reduce the cost of charp tool.
As another kind of improvement of the present invention, the rake face of described cutter head and the angle of horizontal plane are 10-15 ゜.Adopt after this kind of structure cutting effect the best of described cutter head.
Also have one to improve as of the present invention, the upper surface middle part of described body is provided with boss; Described rake face is inclined-plane; Between described rake face and boss, be connected by arcwall face; Between the sidewall of two cutter heads that described body is adjacent, be equipped with projection.Adopt after this kind of structure, described boss and protruding role, all in order to increase the intensity of blade, by arcwall face transition, can decompose the power of the suffered part of blade between described rake face and boss, the pressure having born while having reduced blade work, thereby the service life of prolongation blade.
Also have one to improve as of the present invention, the thickness of described body is 4-5mm.。This kind is designed to the best.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8.
Blade for gear milling cutter device of the present invention comprises body 1.Described body 1 is triangular shaped.On each angle of described body 1, be equipped with cutter head 1.1.The center of described body 1 is provided with installing hole 1.2.The shape of the cross section of each cutter head 1.1 all matches with the shape of the cross section of the teeth groove of processed gear, the cross section of described cutter head is perpendicular to along the face of the center line on cutter head thickness direction, object is that profile and the teeth groove of the cutter head in order to make blade matches, and cuts the teeth groove of gear to be processed.Described body 1 is made by W-Co kind carbide alloy or titanium cobalt series hard alloy or General hard alloy.The rake face of described cutter head 1.1 and the angle a of horizontal plane are 10-15 ゜, and the best angle of described angle is 12 ゜.The upper surface middle part of described body 1 is provided with boss 1.3; Described rake face 1.5 is inclined-plane; Between described rake face 1.5 and boss 1.3, be connected by arcwall face 1.6; Between the sidewall of two cutter heads 1.1 that described body 1 is adjacent, be equipped with projection 1.4.The thickness of described body 1 is 4-5mm, and optimum thickness is 4.5mm.
W-Co kind carbide alloy, conventional trade mark YG3, YG6, YG8, wherein numeral is containing the percentage of cobalt amount, containing cobalt amount the more, toughness better, more shock-resistant and vibration, but can reduce hardness and wearability.Therefore, this alloy is applicable to cutting cast iron and non-ferrous metal, can also be used to blank that cutting-impact is large and steel part and stainless steel part through quenching.Titanium cobalt series hard alloy, the conventional trade mark has YT5, YT15, YT30, the percentage of numeral titanium carbide.Carbide alloy, containing after titanium carbide, can improve the sticking temperature of steel, reduces coefficient of friction, and can make hardness and wearability slightly be improved, but reduced bending strength and toughness, and character is become fragile, and therefore, such alloy adapts to Cutting Steel class part.General hard alloy, in above-mentioned two kinds of carbide alloy, add appropriate rare metal carbide, as ramet and niobium carbide etc., make its grain refinement, improve its normal temperature hardness and high temperature hardness, wearability, bonding temp and non-oxidizability, can make the toughness of alloy increase to some extent, therefore, this series hard alloy cutter has preferably comprehensive cutting ability and versatility, its trade mark has: YW1, YW2 and YA6 etc., because its price is more expensive, be mainly used in difficult-to-machine material, as high strength steel, heat resisting steel, stainless steel etc.
