Description
Technical field
The utility model relates to cutter, relates in particular to a kind of necking tool that is applicable to the lathe grinding technology.
Background technology
Necking tool is a Digit Control Machine Tool cutter commonly used, what the producer that slots with numerically controlled lathe generally adopted at present is that " high-speed steel " cutter is slotted, " high-speed steel " cutter fluting efficient height, but also have significant disadvantages: at first high-speed steelknife is easy to wearing and tearing, and service life is very short.When especially slotting above the guide wheel of 500mm at length, high-speed steelknife is difficult to guarantee that guide wheel is gone into cutter and gone out cutter place flute profile is consistent, as with many when cutter is processed same guide wheel, tangible lapping defect can be occurred again, thereby guide wheel crudy and later stage client use can be influenced to a great extent with high-speed steelknife processing guide wheel.Moreover the guide pulley surface quality of high-speed steel processing is poor.Owing to high-speed steelknife weares and teares easily, just need very high process velocity guide wheel to be machined when processing guide wheel, but high efficiency very difficult simultaneously assurance is high-quality at once, the guide pulley surface quality is difficult to reach very bright and clean effect, and the uniformity of flute profile also is difficult to guarantee.
In order to overcome " high-speed steel " problem that cutter brought, a lot of producers that slot are to slotting with the PCD cutter, the English spelling Polycrystalline of PCD diamond, Chinese polycrystalline diamond by name, it has extraordinary wearability, can solve the existing problem of " high-speed steel " cutter, but the PCD cutter has a significant disadvantages: the PCD cutter is sharp inadequately, is difficult to guarantee crudy during the machined polyurethane guide wheel, and the fluting rear surface has a lot of residues, cause the groove left crude, processed finished products is poor.

Adopt a kind of necking tool advantage of the utility model to be:
1. use a kind of necking tool processing of the utility model back product groove grooved uniformity very high, product surface fineness, " V " type trench bottom R radian of being opened is very little, has strengthened the stability of parts such as embedded thin steel wire wherein.
2. a kind of necking tool of the utility model is installed and is stablized, and its blade sharpness height has effectively avoided point of a knife to collapse the appearance of cutter situation when turning during use.
3. a kind of necking tool fluting of the utility model is effective, and is suitable for the fluting of the line cutting guide wheel of all kinds of models, uses extensively, and is practical.
Description of drawings
Fig. 1 is the side view of a kind of necking tool of the utility model;
Fig. 2 is the vertical view of a kind of necking tool of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, a kind of necking tool comprises cutter hub 1 and the cutter head 2 that is connected on the cutter hub 1, described cutter head 2 is taper, two sides of described cutter head 2 intersect at the point of a knife top, and forming nose angle β is 70 degree, and the summit of described cutter head 2 is on the center line of cutter hub 1 basal plane.Be inlaid with blade 3 on the top of described cutter head 2, the vertical view of necking tool as described, shown in Figure 2, the point of a knife 9 of described blade 3 is a circular arc, the rake face 6 of described cutter head 2 forms anterior angle γ by the beginning of place, summit is downward-sloping with basal plane 5 cutter hub, make described cutter hub 1 and cutter head 2 junctions form " V " type groove 8 like this, described " V " type groove 8 runs through the left and right sides face of described cutter hub 1, and its base angle is 120 degree.The main back knife face 4 of cutter head 2 tilts to described cutter hub 1 inboard from point of a knife 9, with the cutting face 7 formation primary clearance δ of described necking tool.Described blade 3 long 6 millimeters, thick 1.6 millimeters, and made by polycrystalline diamond (PCD) material, characteristic such as PCD hardness height, compression strength height, thermal conductivity and wearability are good can obtain very high machining accuracy and working (machining) efficiency in high-speed cutting.And, adopt the blade embedding technique, after described blade 3 uses a period of time, can carry out sharpening to described blade 3, recover its cutting ability, up to going back changeable blade 3 behind the sharpening, such design has improved the adaptive capacity of cutter well, has also reduced the production cost of cutter.
Necking tool anterior angle γ among Fig. 1 is 15 degree, and primary clearance δ chooses 41 degree, and then the angle of wedge (angle that the rake face 6 of described cutter head 2 and main back knife face 4 form) is 34 degree.In Fig. 2, the nose angle β of described cutter head 2 is 70 degree, and the length of point of a knife 9 circular arcs is 0.02 millimeter.
In the turning grooving process, tool orthogonal rake directly influences the sharpness of edge, it is generally acknowledged, the cutter that anterior angle is big more is sharp more, but if anterior angle is crossed the intensity that conference reduces cutter, also may occur situations such as " collapsing cutter " corrupted sometimes, influences cutter life.And the PCD tool arc has determined the radian of " V " type trench bottom R of being opened, and directly influence embeds the stability of the parts such as thin steel wire of described " V " type trench bottom.The tool arc angle that the utility model adopted can make " V " type trench bottom R radian of the part that goes into operation very little, has strengthened the wherein stability of parts such as embedded thin steel wire so greatly.
Through practice test, add man-hour, adopt the necking tool of above-mentioned utility model, cooperate high-revolving lathe in machining polyurethane material workpiece, the rotating speed of will slotting is controlled at 800 rpms, its linear velocity can reach 900 meters per minutes, finds, in carrying out grooving process, the running of workpiece and necking tool is stable, the groove grooved uniformity height of being opened of the guide wheel of being processed, and surface smoothness height, it is sharp inadequately to have solved common PCD cutter, be difficult to guarantee crudy during the machined polyurethane guide wheel, the fluting rear surface has a lot of residues, causes the groove left crude, problems such as processed finished products difference.On service life, one is adopted the necking tool of present technique can process many guide wheels.But when a kind of other types of necking tool adapted of the utility model, and can solve the fluting problem that all model line are cut guide wheels, its scope of application is wide.
Will be appreciated that; the above embodiments are only as exemplifying and propose preferred embodiment of the present utility model; the utility model also not only is confined to this, and the various simple modifications that those skilled in the art can implement also should fall in the protection domain of the present utility model.
