Kev Nyuaj Siab Thiab Kev Txhim Kho Kev Ntsuas Rau Tapping Me Me hauv Titanium Alloy

Internal threads ntawm qhov me me M6 thiab hauv qab no yog ib qho kev sib sib zog nqus kev sib txuas cov qauv ntawm titanium alloy qhov chaw. Txawm li cas los xij, txwv tsis pub los ntawm cov khoom siv thiab qhov chaw nqaim nqaim, tapping qhov me me yog cov txheej txheem nyuaj nrog kev tsis lees paub siab. Cov teeb meem xws li kais tawg, xov puas, khawb qhov chaw thiab qhov loj me tawm - ntawm - kev kam rau siab nquag tshwm sim, uas degrade qhov raug sib dhos thiab kev pab cuam lub neej ntawm cov khoom.

 

 

 

1. Cov khoom siv aggravate kev sib txhuam thiab deformation

Titanium alloymuaj ib tug tsis tshua muaj elastic modulus. Tom qab machining, lub qhov phab ntsa rebounds thiab clamps tus kais kom nruj, uas ua rau ntau dua tapping torque dua hlau. Nws cov plasticity zoo yooj yim ua rau ua - nce ntug, ua rau cov xov burrs thiab qhov sib txawv ntawm qhov sib txawv. Lub siab shear zog coj loj txiav quab yuam, uas accelerates kais coj thiab puas.

 

2. Cov cua kub tsis zoo ua rau cov cuab yeej hnav sai

Titanium alloy nthuav tawm tsis tshua muaj thermal conductivity, yog li feem ntau txiav cov cua sov accumulates ntawm cov npoo. Qhov chaw kaw hauv qhov me me ua rau nws nyuaj rau xa cov kua dej txiav. Qhov kub kub hauv zos ua rau muaj ntau hom kev hnav, thiab cov oxide txheej ua rau ntawm qhov chaw ua haujlwm, tsim kom muaj lub voj voog tsis zoo ntawm qhov kub siab - qhov kub thiab txias.

 

3. Cov nti nti tawm tsis zoo yooj yim ua rau nti txhaws thiab tsis kam ua haujlwm

Cov qhov me me muab qhov chaw nyob tsawg nti. Nruam, hloov tau yooj yim titanium alloy chips yog ib qho nyuaj rau kev tawg, nws yooj yim rau winding thiab clogging nti flutes, uas khawb threads. Chip blockage nce machining torque thiab yooj yim twists tawm kais dej, thiab nti tsub zuj zuj nyob rau hauv qab ntawm qhov muag tsis pom qhov ua rau muaj teeb meem loj dua.

 

4. Tsis txaus rigidity ntawm me me kais dej ua rau tsis zoo machining raug

Cov kais dej rau M6 thiab hauv qab no muaj nyias diameters thiab tsis muaj zog rigidity. Lawv zoo li vibrate thiab deform nyob rau hauv txiav quab yuam, ua rau tsis tsim nyog ntawm xov coaxiality thiab suab raug. Cov ilv txiav npoo tawg nyob rau hauv me ntsis overload, thiab tawg kais yog nyuaj rau extract, ncaj qha scrapping lub workpiece. Cov txheej txheem kais dej nrog cov raj nplaim zoo tib yam thiab cov hniav profiles tsis haum rau titanium alloy machining, ntxiv rau qhov tsis xws luag.

 

 

1. Xaiv cov kais dej tshwj xeeb thiab txhim kho lawv cov qauv

Tso tseg cov txheej txheem zoo tib yam kais dej thiab txais yuav cov cemented carbide lossis coated siab - ceev steel tshwj xeeb kais. Cov txheej yuav txo tau kev sib txhuam thiab tiv thaiv kev ua - nce ntug. Hais txog cov qauv, hla- cov hniav kais dej uas muaj cov hniav tsawg dua thiab cov nplais loj loj raug xaiv los txhim kho nti tshem tawm. Nthuav lub khob hliav qab thiab txais yuav lub khob hliav qab loj kom tawg cov khoom tawg; luv-ntug kais dej yog siv rau qhov dig muag qhov. Txiav ntug passivation kev kho mob txo cov ntug chipping thiab txhim kho xov nto tiav.

 

2. Ua kom lub hauv qab qhov loj me me thiab lav qhov zoo hauv qab

Loj lub kais laum txoj kab uas hla raws li xov specifications: ntxiv 0.05-0.1 hli machining nyiaj pub rau M2-M3 threads, thiab 0.1-0.15 hli rau M4-M6 threads. Qhov nyiaj pub dawb no haum rau cov khoom siv springback, txo cov extrusion torque, thiab tiv thaiv kais qaug dab peg thiab tawg. Txais cov kauj ruam drilling ua raws li los ntawm reaming kom lav zoo kawg nkaus puag ncig, du bore nto.

 

3. Sib tw qis- ceev txiav tsis tau thiab txais yuav segmented rau pem hauv ntej thiab rov qab tapping

Thaum machining Ti-6Al-4V titanium alloy, siv qis qis, zoo sib xws spindle ceev ua ke nrog lub teeb pub tus nqi:

M2-M3 kais dej: 80-120 r / min

M4-M6 kais dej: 120-180 r / min

Tshem tawm cov kais dej tom qab txhua 2-3 xov pitches kom tshem cov chips; Qhov no rhuav tshem cov ribbon chips txuas ntxiv thiab ua kom yooj yim rau cov cua sov dissipation. Rau qhov sib sib zog nqus qhov tapping, txo qhov tob ntawm txhua qhov pub dhau thiab ua kom cov kais retraction zaus.

 

4. Txhim kho lub siab txias thiab lubrication system

Siv - siab tapping roj tshwj xeeb tsim rau titanium alloy. Hnyav- cov khoom siv siab ntxiv tsim cov zaj duab xis lubricating kom txo kev sib txhuam thiab tiv thaiv- adhesion rau cov cuab yeej txiav. Ua ntej cov kais dej nrog rau sab hauv siab -siab txias rau cov kua dej. Yog tias cov khoom siv cua txias sab hauv tsis muaj, txais yuav drip infiltration lubrication; lubricating paste tuaj yeem siv rau kev ua tiav tapping kom txuas ntxiv yaug cov chips tawm ntawm qhov.

 

5. Ua kom zoo dua cov cuab yeej thiab cov cuab yeej, thiab xaiv tau ultrasonic-pab machining

Hloov phau ntawv tapping nrog CNC tsis siv neeg tapping, nruab nrog siab -precision floating chucks los them cov coaxial yuam kev. Ultrasonic vibration tapping tuaj yeem siv rau siab - precision machining kom tawg cov chips, dissipate tshav kub thiab qis txiav tsis kam. Calibrate fixtures ua ntej machining los xyuas kom meej qhov chaw ruaj khov tsis muaj workpiece offset.

 

6. Txuj kev tshaj tawm -kev kho mob thiab tag nrho- txheej txheem kev tshuaj xyuas zoo

Ntxuav cov chips thiab roj residue hauv qhov nrog cov cua txhuam tom qab tshuab, thiab tshem cov kais dej ntawm qhov ceev kom tsis txhob muaj xov khawb. Ua kev sim txiav los ntsuas tag nrho cov xov ntsuas ua ntej ntau lawm, ua cov qauv kuaj xyuas ib ntus thaum lub sijhawm ua haujlwm, hloov cov cuab yeej hnav raws sijhawm thiab kho cov txheej txheem tsis tu ncua kom ruaj khov tus nqi ntawm cov khoom tiav.
