Abstract
The invention discloses an external cutter tooth of a hard alloy frontal-arc milling cutter, comprising integrally formed connecting part and cutting part, wherein the cutting part is provided with a main cutting blade, a chip removal groove is formed at one side of the connecting position of the connecting part and the cutting part, and the chip removal groove is located at one side back to the main cutting blade. By adopting the external cutter tooth of the hard alloy frontal-arc milling cutter, disclosed by the invention, chip removal is smooth, heat dissipation is good, service life is long, and the milling and machining efficiency of basin apical teeth is effectively improved.
Description
Technical field
The present invention relates to a kind of machining tool structure, especially the outer cutter tooth of hard alloy frontal arc milling cutter.
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 part material, in machining process, there is the problem of chip removal difficulty, difficulty of processing is large, and efficiency is low.
Summary of the invention
For solving above technical problem, the invention provides a kind of chip removal outer cutter tooth of hard alloy frontal arc milling cutter smoothly, to improve working (machining) efficiency.
Its technical scheme is as follows:
The outer cutter tooth of a kind of hard alloy frontal arc milling cutter, comprise integrated coupling part and cutting tip, described cutting tip has main cutting edge, the side of described coupling part and cutting tip connecting portion is provided with chip removal groove, described chip removal flute slot is in the side deviating from main cutting edge, chip removal groove is set in cutter tooth side, the iron filings produced in process are skidded off along chip removal groove, contribute to improving working (machining) efficiency.
As preferably, the width of described coupling part is less than the width of cutting tip, this cutting tip being provided with inside arc-shaped recess structure with coupling part connecting portion, to ensure that chip removal is smooth and easy further
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, 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.
Described coupling part is preferably rectangular structure, to further facilitate the connection between cutter tooth and cutter hub, described cutting tip entirety is in wedge structure, along the direction away from coupling part, its thickness reduces gradually, this structure can reduce the friction between the forward and backward knife face of cutter and metal fillings, machined surface, ensures the sharp keen and intensity of cutting edge roundness, contributes to improving working (machining) efficiency.
Beneficial effect:
The outer cutter tooth of hard alloy frontal arc milling cutter of the present invention, chip removal is smooth and easy, and heat radiation is good, and long service life, effectively improves the Milling Process efficiency of basin angle tooth.
