Abstract
The utility model relates to an indexable threaded blade which comprises a cutter body, wherein a mounting hole is formed in the middle of the cutter body; three working faces are arranged on the cutter body; one cutting edge is arranged on each of the working faces; each of the cutting edges is buttress-shaped; a front cutter face is arranged on each of the cutting edges; each of the front cutter faces is connected with the cutter body through a chip removal arc surface; an included angle between each of the front cutter faces and the vertical line of the horizontal plane is between 15 degrees 20 minutes and 14 degrees 40 minutes; each of the cutting edges is composed of an addendum machining face, a left side machining face and a right side machining face; an included angle between the left side machining face and the vertical line of the horizontal plane is between 3 degrees 15 minutes and 2 degrees 45 minutes; an included angle between the right side machining face and the vertical line of the horizontal plane is between 10 degrees 15 minutes and 9 degrees 45 minutes. The indexable threaded blade is reasonable in design, the larger front cutting edge included angles and the reasonable radius of the chip removal arc surface are adopted to enhance the chip removal effect and prevent scrap iron from twining and stacking; the included angles between the left side machining faces and the vertical line of the horizontal plane and between the right side machining faces and the vertical line of the horizontal plane are reasonable in design, so that the cutting resistance is reduced, the cutting edges cannot be worn easily, and the service life of the indexable threaded blade is prolonged.
Description
Technical field
The utility model relates to a kind of threaded blade, especially relates to a kind of indexable threaded blade.
Background technology
In turning processing, buttress thread is because total cutting depth is large, and tool dimension is subject to the restriction of trapezoidal thread physical dimension.On market, existing tool stiffness is poor, and precision is low, and cutting resistance is large, and chip removal is not smooth, and iron filings are easily wound around, and makes cutting edge excess Temperature, serious wear, cutting edge easy fracture.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides that a kind of precision is high, cutting resistance is little, chip removal is smooth and easy, the indexable threaded blade of long service life.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of indexable threaded blade, comprise cutter hub, the middle part of described cutter hub is provided with installing hole, described cutter hub is provided with three working faces, described each working face is provided with 1 cutting edge, being shaped as of described cutting edge is partially trapezoidal, described cutting edge is provided with rake face, described rake face is connected with cutter hub by a chip removal arc surface, angle between described rake face and the vertical line of horizontal plane be 15o ± 20 ', described cutting edge is by tooth top machined surface, left side machined surface and right side machined surface composition, angle between described left side machined surface and the vertical line of horizontal plane be 3o ± 15 ', angle between described right side machined surface and the vertical line of horizontal plane be 10o ± 15 '.
Further, the radius of described chip removal arc surface is 2.5mm.
The beneficial effects of the utility model are: the indexable threaded blade reasonable in design of the utility model, adopt larger rake face angle, and the radius of rational chip removal arc surface, strengthen chip removal effect, prevent winding and the accumulation of iron filings; Angle angle design between left side machined surface, right side machined surface and the vertical line of horizontal plane of cutting edge is reasonable, and cutting resistance is reduced, and cutting edge is not easy to wear, the long service life of blade.Cutter hub is provided with three working faces, in real work, if the cutting edge of a working face damages, can directly insert to another working face, carries out work.
Accompanying drawing explanation
Fig. 1 is the structural representation of the indexable threaded blade of the utility model.
Fig. 2 is D-D cutaway view in Fig. 1.
Fig. 3 is the structural representation of the cutting edge of the indexable threaded blade of the utility model.
Number in the figure explanation: 1: cutter hub, 2: installing hole, 3: working face; 4: cutting edge, 41: tooth top machined surface, 42: left side machined surface, 43: right side machined surface, 5: rake face, 6: chip removal arc surface.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1 to Figure 3, a kind of indexable threaded blade, comprises cutter hub 1, and the middle part of described cutter hub 1 is provided with installing hole 2, for blade is arranged on to knife rest.Described cutter hub 1 is provided with three working faces 3, and described each working face 3 is provided with 1 cutting edge 4, and being shaped as of described cutting edge 4 is partially trapezoidal, for processing buttress thread.Described cutting edge 4 is provided with rake face 5, described rake face 5 is connected with cutter hub 1 by a chip removal arc surface 6, angle α between described rake face 5 and the vertical line of horizontal plane be 15o ± 20 ', the radius R of chip removal arc surface 6 is 2.5mm, such design has strengthened chip removal effect, prevents winding and the accumulation of iron filings.Cutting edge 4 is made up of tooth top machined surface 41, left side machined surface 42 and right side machined surface 43, angle β between described left side machined surface 42 and the vertical line of horizontal plane be 3o ± 15 ', angle γ between described right side machined surface 43 and the vertical line of horizontal plane is 10o ± 15, design rational angle, cutting resistance is reduced, cutting edge is not easy to wear, the long service life of blade.In addition, cutter hub is provided with three working faces 3, in real work, if the cutting edge of a working face damages, can directly insert to another working face, carries out work, and production efficiency is high.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
