Description
Technical field
The present invention relates to a kind of cutting tool in machining field, particularly a kind of cutting GH4169 alloy
Micro structure carbide-tipped lathe tool piece.
Background technology
Machining is the Main Means that machinery manufacturing industry material removes, and the quality of cutting tool directly affects cutting
The efficiency of processing and crudy.In machining, cutting edge is as main portions, cutting edge and the cutting edge removing material
(cutting edge near field refers to the tiny area near cutting edge on cutter rake face, dotted line bag in such as Fig. 2 in neighbouring rake face region
The region enclosed) working environment is the most severe, and its structure is directly connected to cutting wear and the efficiency processed and quality
Processing, so rational cutting edge and cutting edge near field structure design are particularly important to the performance of lifting lathe tool.Industry pair at present
The structure design of cutter rake face is concentrated mainly on the design of antifriction groove and chip-breaker, the former be primarily upon how reducing cutter with
The friction of chip bottom metal, to reduce the purpose that cutting temperature improves durability, the latter is concerned with how that appropriate design makes
Chip can fracture as requested or bend, it is to avoid impact processing and machined surface quality.During machining, the temperature meeting of cutter
Drastically raise, this not only can reduce cutting wear, but also machining quality can be reduced.Industry mainly adopts at present
Cooling means be processing when lowered the temperature using coolant, this cool-down method can only reduce lathe tool surface temperature you.By above-mentioned
Understand, how current industry does not also reduce the structure design to lathe tool cutting edge near field for the cutting temperature.
Content of the invention
It is an object of the invention to, provide a kind of rake face cutting edge near field micro structure of cutting GH4169 alloy hard
Matter alloy turning insert.The present invention has the characteristics that to reduce cutting temperature and improves tool life.
Technical scheme：A kind of cutting GH4169 alloy micro structure carbide-tipped lathe tool piece, including before
Knife face, the edge of rake face is provided with main cutting edge, is provided with microflute at the cutting edge near field of rake face；Described microflute is in not right
Claim, the overall not wide and deep J-type micro structure such as not.
In the micro structure carbide-tipped lathe tool piece of aforesaid cutting GH4169 alloy, described microflute is on rake face
Section be asymmetrical curve type, the bottom surface of microflute is in plane or cambered surface, and depth capacity H of microflute is 0.27～0.34mm.
In the micro structure carbide-tipped lathe tool piece of aforesaid cutting GH4169 alloy, length L of described microflute is
2.15～2.66mm, the width W of microflute is 0.89～1.21mm.
In the micro structure carbide-tipped lathe tool piece of aforesaid cutting GH4169 alloy, the close master of described microflute cuts
Cutting the outer rim of sword side minimum range T away from main cutting edge is 0.06～0.09mm.
In the micro structure carbide-tipped lathe tool piece of aforesaid cutting GH4169 alloy, the described outer rim of microflute and master
The type of attachment of cutting edge is equal height type and not equal height type.
In the micro structure carbide-tipped lathe tool piece of aforesaid cutting GH4169 alloy, along knife face direction after master
Observation, the linear type of described main cutting edge or arc line type.
Beneficial effect
Compared with prior art, the present invention passes through to arrange the micro groove structure of J-type at rake face cutting edge near field, makes cutter
When cutting GH4169 alloy, the temperature reduction of knife-bits actual contact area (this region be located at cutting edge near field) thus
Effectively improve cutting wear.It is known that cutter is in working angles, knife-bits contact area can occur severe friction and shape
Become, produce localized hyperthermia's high pressure, produce a large amount of heat in metal cuttings；There is shearing slip in primary deformation zone in working angles simultaneously, cuts
The anti-shearing work of deformation almost all cutting region is converted into heat in metal cutting, through the transmission of heat, also results in Tool in Cutting temperature
Rising.In the present invention, applicant by finding to the many experiments analysis of GH4169 alloy, when on rake face away from master
(this distance is the outer rim of close main cutting edge side away from main cutting edge to the distance of cutting edge 0.06～0.1mm (optimum is 0.1mm)
Distance, i.e. T) insert " J " type micro groove structure, between 0.27～0.34mmmm and length L of microflute is depth capacity H of microflute
When 2.15～2.66mm, Breadth Maximum W are 0.89～1.21mm, the new construction of cutting edge near field has more apparent cooling-down effect；Main
If because：1) presence of microflute increases chip and cutter rake face contact area, reduces cutter in knife-bits contact position area
Direct stress, this direct stress gradually decreases to a certain marginal value, reduces the possibility that internal friction occurs inside chip underlying metal,
So that script knife-bits contact area part internal friction regioinvertions are converted into sliding friction for the external friction region friction zone that bonds
Area, because internal friction region is the main source region of cutter heat, the reduction in this region result in tool temperature and reduces；2) micro-
The presence of groove changes the Thermal-mechanical Coupling effect of tool cutting process, changes primary deformation zone stress-strain state, improves
Primary deformation zone shearing slip, reduces the generation of heat in metal cutting.Comprehensive function makes Tool in Cutting temperature effectively be reduced, and then
Effectively ensure that the durability of lathe tool.
When using, microflute also has the function of chip breaking to the present invention, and microflute makes in working angles chip along its Surface runoff,
Curved surface produces certain barrier effect so that chip crimps to the flowing of chip, when chip flows through outside microflute
During edge, by the high stress at this, when cutting because the strain being occurred by local stress effect reaches its limiting strain
During value, chip can fracture.Compared with common chip-breaker and antifriction groove, the difference of microflute of the present invention, except above-mentioned
Outside design principle, microflute location, mainly in the knife-bits contact area of rake face cutting edge near field, yardstick is generally less than
Chip-breaker and antifriction groove, and the scope of its present position is relatively distant from main cutting edge；In working angles microflute cutter of the present invention with
The contact shape of chip bottom almost Full connected or overwhelming majority contact (as shown in Fig. 6-Figure 11), increases knife before chip and cutter
Face contact area, reduces the direct stress in knife-bits contact position area for the cutter；And commonly antifriction groove cutter contact with chip bottom
For incomplete contact between, because the design main purpose of common antifriction groove is to reduce cutter contact with chip bottom.
Prove beneficial effects of the present invention in order to be able to more preferable, applicant has done following emulation experiment：Closed using ordinary rigid
Golden turning insert (hereinafter referred to as compareing lathe tool) carries out cutting GH4169 alloy simulation comparison with the present invention.
All in identical machining condition, (cutting data, cutter are several for each group of contrast experiment of above-mentioned comparison lathe tool and the present invention
What structure, cutter and workpiece material etc.) under carry out, the simulation comparison experiment scheme of cutting GH4169 alloy and result such as table
Shown in 1.
Table 1
As shown in Table 1, the highest of cutter can effectively be reduced using the present invention, cooling extent reaches 10～25%, cooling-down effect
Substantially.
