Abstract
The invention discloses a hard alloy basin angle tooth milling cutter tooth. The hard alloy basin angle tooth milling cutter tooth comprises a connecting part and a cutting part integrally molded, wherein a cutting insert is embedded in one side of the cutting part. The hard alloy basin angle tooth milling cutter tooth is characterized in that a chip removing groove and a cooling liquid runner are respectively arranged at the two sides of a connected part between the connecting part and the cutting part; and the chip removing groove is positioned at one side opposite to the cutting insert. The hard alloy basin angle tooth milling cutter tooth is simple and novel in structure, smooth in chip removal, excellent in heat dissipating performance, long in service life and in favor of improving the machining efficiency of basin angle teeth.
Description
Technical field
The present invention relates to a kind of machining tool structure, especially hard alloy basin angle tooth milling cutter tooth.
Background technology
Basin angle tooth is also known as dish angle tooth, and be widely used in mechanical transmission fields, when being applied in the larger equipment of the load such as automobile, engineering machinery, basin angle tooth adopts the Hardmetal materials such as 20CrMnTiH1 usually.Affect by its hardness, in machining process, there is chip removal difficulty, the problem such as to dispel the heat bad, and difficulty of processing is large, stock-removing efficiency is low.
Summary of the invention
For solving above technical problem, the invention provides a kind of hard alloy basin angle tooth milling cutter tooth facilitating chip removal and heat radiation, to improve working (machining) efficiency.
Its technical scheme is as follows:
A kind of hard alloy basin angle tooth milling cutter tooth, comprise integrated coupling part and cutting tip, described cutting tip side is embedded with cutting insert, its key is: the both sides of described coupling part and cutting tip connecting portion are respectively equipped with chip removal groove and cooling liquid flowing channel, described chip removal flute slot is in the side deviating from cutting insert, be arranged on the chip removal groove of cutter tooth side, the iron filings produced in process are skidded off along chip removal groove, the chip removal groove being positioned at cutting insert homonymy can increase the contact area of the cutting tip of cooling fluid and cutter, substantially increase radiating effect.
As preferably, the anterior angle of described cutting tip is 10 ~ 15 °, and relief angle is 25 ~ 40 °, and this structure can reduce the friction between cutting edge and workpiece, improves cutter heat dispersal situations further, tool life.
Described cutting insert is globoidal structure near the side sidewall of cooling liquid flowing channel, and this sidewall be arranged in this cooling liquid flowing channel at least partially, to increase the area of dissipation of cutting insert further, improve radiating effect.
For convenience of Cutting tool installation manner, installing hole through before and after being provided with in the middle part of described coupling part.
For further facilitating connection, described coupling part is preferably rectangular structure.
Described cutting tip entirety is in wedge structure, along away from the direction of coupling part, its thickness reduces gradually, and this structure can reduce the friction between the forward and backward knife face of cutter and metal fillings, machined surface, ensure the sharp keen and intensity of cutting edge roundness, contribute to improving working (machining) efficiency.
Beneficial effect:
Hard alloy basin angle of the present invention tooth milling cutter tooth, its structure is simply novel, and chip removal is smooth and easy, has good heat dispersion, and long service life, the working (machining) efficiency contributing to improving basin angle tooth is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view along A-A line in Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
A kind of hard alloy basin angle tooth milling cutter tooth as shown in Figure 1, comprise the cutting tip 2 of coupling part 1 in rectangular structure and wedge structure, this cutting tip 2 and coupling part 1 are formed in one structure, connecting hole 11 through before and after coupling part 1 is provided with at the middle part of its length direction, cutting tip 2 is inlaid with the cutting insert 3 of hard material in its side.
Cutting tip 2 has rake face 21 and rear knife face 22, chip removal groove 4 and cooling liquid flowing channel 5 is respectively equipped with in the both sides of coupling part 1 and cutting tip 2 connecting portion, wherein, chip removal groove 4 is positioned at the side deviating from cutting insert 3, cooling liquid flowing channel 5 is positioned at cutting insert 3 homonymy, and the bearing of trend of chip removal groove 4 and cooling liquid flowing channel 5 is parallel to rear knife face 22 or arranges in acute angle with rear knife face 22.
The anterior angle Kr of cutting tip 2 is 10 ~ 15 °, and relief angle Kr ' is 25 ~ 40 °, in the present embodiment, and anterior angle Kr is preferably 12 °, and relief angle Kr ' is preferably 30 °.
Coupling part 1 is provided with the sunk structure of this cutting insert 3 accommodating, and cutting insert 3 embeds in sunk structure, and the end face outside of cutting insert 3 protrudes sunk structure surprisingly, within making a part for the inner sidewall 31 of this cutting insert 3 be positioned at cooling liquid flowing channel 5.
Composition graphs 2 can be found out, the thickness of cutting tip 2 and cutting insert 3 reduces gradually along the direction away from coupling part 1, and this cutting insert 3 is positioned at the side sidewall 31 of cooling liquid flowing channel 5 in globoidal structure.
Finally it should be noted that; foregoing description is only the preferred embodiments of the present invention; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite without prejudice to present inventive concept and claim; can make like multiple types and representing, such conversion all falls within protection scope of the present invention.
