Abstract

The invention relates to a double-arc irregular shaped inner-cooling type efficient titanium alloy milling tool. High processing difficulty, low cutting efficiency and short service life of a tool are caused by the mutual influence of physical, chemical and mechanical properties of titanium alloy, so that the titanium alloy becomes a typical difficultly processed material. The double-arc irregular shaped inner-cooling type efficient titanium alloy milling tool comprises a tool handle (1), wherein the tool handle (1) is transited to a milling tool bit with a double-arc shape at the front end through a cone (2); a pair of chip pockets (6) with front angle structures are arranged on one side of the tool bit; a cooling liquid channel (5) is arranged at the center of the tool; an outlet of the cooling liquid channel is located on the end part of the tool; and a negative chamfered edge (7) is arranged on the tail part of the tool. The invention is applied to the milling tool.

Description

Two circular arc abnormity inner-cooled titanium alloy high-efficient milling cutters
Technical field
the present invention relates to a kind of milling cutter.
Background technology
Difficulty of processing is big, stock-removing efficiency is low, cutter life is short owing to influencing each other of titanium alloy physics, chemistry and mechanical performance caused , makes it become a kind of typical difficult-to-machine material.Its main s cap processing is following:
(1) smear metal and the rake face contact area is little, point of a knife stress is big, temperature is high, thus point of a knife and cutting edge easy abrasion made.
(2) coefficient of friction is big.Under the same conditions, titanium alloy material is compared with ordinary carbon steel, and its coefficient of friction is big, and the frictional work of being done when rake face is flowed through in smear metal is big, causes the frictional interface temperature higher, makes cutter be easy to wearing and tearing.
(3) chemism is high.Chemism is very high during titanium alloy high-temperature; Can chemical reaction take place with airborne oxygen, nitrogen and steam etc.; Generate hardened layer at titanium alloy surface; Cause workpiece hardness to increase substantially, reduced workpiece plasticity simultaneously and made smear metal and the contact length of rake face further reduces, cause tool wear to be accelerated.
(4) pyroconductivity is low.The thermal conductivity factor of titanium alloy have only respectively iron 1/5, aluminium 1/14, the contact length of cutter and smear metal is short in addition, makes heat in metal cutting accumulate near the small size the cutting edge and is difficult for distributing, and causes the cutter temperature too high, has accelerated the wearing and tearing of cutter.
(5) elastic modelling quantity is little.Because the titanium alloy elastic modulus is little, yield tensile ratio is big, makes the own finished surface of workpiece in working angles, very easily produce resilience, cause the wear of the tool flank aggravation and the workpiece deformation of cutter easily.
Have relatively high expectations to lathe (6).Cutting of Ti Alloy requires lathe good rigidly, vibration little, and the process system to lathe has certain requirement in use, and the machine tool chief axis beat is little; Knife rest and whole machining process system rigidity will be got well; And machine vibration is little, and anti-cutter generation tipping is to improve the reliability of experimental data.

Beneficial effect:
1. the present invention solve problems such as titanium alloy cutting temperature height, the too early wear out failure of cutter and high-speed milling in semifinishing and fine finishining process be not steady, effectively improve cutter life-span and working (machining) efficiency, reduce production costs.
top 2. of the present invention bulb partly adopts two circular arc surdimensionnement, and position, ball head knife tip is the small curve circular arc, and bulb tip and cone excessively part are the deep camber circular arc.The cutter head of two arc structures, its axial cross section are oval, under the prerequisite that guarantees the cutter rigidity, have improved the point of a knife tapering of cutter to greatest extent, thereby have improved the sharpness of cutter, have effectively reduced the axial force of cutter in working angles simultaneously.
When 3. the present invention adopts this structure to produce above advantage; Not only can increase the contact area of cutting edge and surface of the work; Improve surface removal rate, the raising production and processing efficient of material, and can also effectively reduce processing cost.
chip pocket 4. of the present invention adopts the semiclosed grooved design of big plot ratio, and is the helical angle about 1 ° from point of a knife toward its bottom land of handle of a knife direction and handle of a knife central shaft.This design has improved the particularly discharge efficient of chip of smear metal; Can effectively guarantee handle of a knife rigidity and anti-crawl agentdefiection ability in the helical angle about 1 ° under the situation of high-speed milling, simultaneously smear metal and cooling fluid are ejected along the arc cell wall, thereby heat in metal cutting is taken away by smear metal and cooling fluid; The chip pocket of big plot ratio can effectively increase the area of dissipation that cutter is participated in the cutting position, can play dispersion simultaneously.
The optimal curvature of two arc cutters sub-district rate circular arc and deep camber circular arc has been announced in 5. the present invention; Realized the outflow of two arc cutter cleaning fluids like this; Cutting effect, the optimize results of running such as stage property intensity has improved industrial efficient and accuracy.
