Chip breaking；The outflow direction that iron filings can effectively be stopped by one end of tattooing handle simultaneously, when iron filings are flowed out by the salient point at chip space bottom
When encountering one end of tattooing handle, one end of tattooing handle forms obstacle energy moment and fractures and iron filings or form fragment shape, greatly promotes the disconnected of cutter
It considers performance to be worth doing, to preferably realize that turning automation, workshop be unmanned, the progress of work of machine substitute human labor, is answered conducive to being widely popularized
With.
With reference to the accompanying drawing with embodiment, the present invention will be further described.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is the schematic view of the front view of the utility model.
Fig. 3 is the side structure schematic view of the utility model.
Specific embodiment
Embodiment: see Fig. 1 to Fig. 3, a kind of back vehicle indexable insert tip, throw away tip of the utility model comprising if mounting body 1 and
Dry to be symmetricly set on the cutting cutter hub 2 in the mounting body 1 in the center of circle, the appearance profile of the mounting body 1 is square, the peace
The center for filling main body 1 is equipped with countersunk head through-hole 11.The countersunk head through-hole 11 locking, which is passed through, by screw is mounted on fixed turning tool rod
On.The quantity of the cutting cutter hub 2 is two, is symmetricly set in the two opposite side walls of mounting body 1 in the center of circle.Other implementations
In example, the appearance profile of the mounting body 1 may be round or other shapes, and the quantity of cutting cutter hub 2 may be three
It is a or four etc..
For lift structure intensity, the mounting body 1 and cutting cutter hub 2 are integrated connection structure.The cutting cutter hub 2 is excellent
It is selected as hard alloy component, metal/ceramic part, polycrystal cubic boron nitride component or polycrystalline diamond stone-arch culvert, hardness is high, makes
It is long with the service life.
The rake face of the cutting cutter hub 2 inwardly concaves to form chip-breaker 21 close to the lateral edge locations of main flank, this is disconnected
The bottom surface for considering slot 21 to be worth doing is equipped at least two salient points 22.It is other equipped with being sequentially arranged at intervals there are four salient point 22 in the present embodiment
In embodiment, the quantity of the salient point 22 can be three, five or more.
The appearance profile of the salient point 22 can be round, oval, triangle and other rules or irregular polygon
Shape.
Tool strength has can be improved in the salient point 22, reduces the contact surface for being removed iron filings and cutter groove, and reduction rubs
It wipes, for heat dissipation and good cooling and lubricant effect, while also aggravating the bending curling of chip, be conducive to chip breaking.
The side wall of the chip-breaker 21 is equipped with one end of tattooing handle 23.In the present embodiment, the quantity of the one end of tattooing handle 23 is three
It is a, it is arranged on the side wall of chip-breaker 21.It, can be according to the number of required corresponding setting one end of tattooing handle 23 in other embodiments
Amount.Preferably, the height of projection of the one end of tattooing handle 23 is preferably 0.1 ~ 1.5mm.The one end of tattooing handle 23 is used to hinder shelves iron filings, when
It is removed iron filings and passes through the chip-breaker 21 with salient point 22, fracture or formed the bending elastic slice of short and small shape after iron filings meet obstructions
Shape, fracture iron filings again after the bending elastic slice shape that iron filings form certain length.
The tool cutting edge angle a of the cutting cutter hub 2 is 25 ~ 35 degree.The bottom surface of the chip-breaker 21 be inclined surface, the inclined surface with
Angle b between rake face is 5 ~ 20 degree.Design of the angle b from 5 degree to 20 degree is to change knife in different materials cutting
The sharpness of piece, purpose change the intensity for cutting main cutting edge.
The rake face 24 of the cutting cutter hub 2 is equipped with the excessive slot being connected with the chip-breaker 21 close to position of tool tip
25, iron filings flowing is more conducive to by excessive slot 25 and bending crimps.
When processing, due to being equipped with salient point 22 on the bottom surface of chip-breaker 21, tool strength can be improved, reduces cutting to slot
The friction at bottom and rake face 24, prolongs the service life, while also aggravating the bending curling of chip, is conducive to chip breaking；Then pass through resistance
Gear boss 23 can effectively stop the outflow direction of iron filings, when iron filings encounter one end of tattooing handle by the outflow of salient point 22 at chip space bottom
When 23, one end of tattooing handle 23 formed obstacle energy moment fracture iron filings or formed fragment shape, chip-breaking performance is good, can preferably realize vehicle
Cut that automation, workshop be unmanned, the progress of work of machine substitute human labor.
According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned reality
