Dab tsi yog Drawing Technologies ntawm Titanium Hlau?

titanium hlau yog ib qho tseem ceeb titanium ua cov khoom, thiab nws cov precision thiab kev ua tau zoo ncaj qha txiav txim siab qhov zoo ntawm cov khoom muaj feem xyuam. Cov txheej txheem kev kos duab yog cov cuab yeej tseem ceeb rau "txo txoj kab uas hla thiab txhim kho precision" ntawmtitanium hlau.Los ntawm cov pob zeb ntxhib mus rau micron - theem precision titanium hlau, kev ua tiav hauv cov txheej txheem kos duab txuas ntxiv ua rau kev txhim kho ntawm titanium hlau daim ntaub ntawv.

 

I. Dab tsi yogTitanium Hlau Drawing txheej txheem?

Nrog rau cov yas deformation ntawm titanium, titanium billets raug yuam kom dhau los ntawm kev tuag nrog ib qho aperture nyob rau hauv tensile quab yuam kom txo tau tus ntoo khaub lig-sectional cheeb tsam thiab nce qhov ntev, thaum kawg tau txais titanium hlau. Piv nrog rau cov hlau thiab txhuas, titanium muaj chav tsis zoo - kub plasticity, siab deformation tsis kam, thiab nws yuav ua rau adhesion tuag. Yog li cov txheej txheem kev kos duab muaj cov kev cai nruj dua rau cov tsis, tuag, thiab lubrication.

II. Cov txheej txheem tseem ceeb txuas ntawm Titanium Hlau Drawing

1. Pleev Pretreatment

Raws li lub hauv paus ntawm kev kos duab, nws ncaj qha cuam tshuam cov txheej txheem stability thiab tiav cov khoom zoo.

Kev kho saum npoo- siv cov tshuaj sib xyaw ntawm hydrofluoric acid thiab nitric acid kom tshem tawm cov tawv TiO₂ oxide nplai thiab tsim cov zaj duab xis passivation;

Annealing kev kho mob- cua sov ntawm 600-800℃kom tshem tawm kev ntxhov siab sab hauv ntawm qhov loj-loj lossis titanium alloy blanks thiab txhim kho plasticity;

Tswj lub flatness thiab roundness ntawm lub ntsej muag dawb paug kom tsis txhob muaj kev ntxhov siab tsis sib xws uas ua rau tuag hnav lossis titanium hlau eccentricity.

 

2. Tuag System

Ib qho tseem ceeb tivthaiv uas txiav txim siab qhov tseeb qhov tseeb thiab qhov zoo ntawm titanium hlau. Cov tuag yuav tsum muaj siab hardness, hnav tsis kam, thiab tiv thaiv -adhesion. tungsten carbide thiab polycrystalline pob zeb diamond (PCD, ntau haum rau ntau- dhau daim duab ntawm precision titanium hlau) feem ntau yog siv. Hom lub qhov tau txais cov qauv sib xyaw ntawm lub conical inlet, thaj chaw ua haujlwm, qhov loj me, thiab qhov hluav taws xob cheeb tsam. Lub khob hliav qab ntawm qhov chaw ua haujlwm yuav tsum tau tswj xyuas kom meej- me me dhau los ua rau muaj kev sib txhuam me me thiab nws yooj yim rau khawb, thaum loj heev yooj yim ua rau "kab xyoob sib koom- zoo li" tsis xws luag ntawm titanium hlau.

 

3. Lubrication thiab txias system

Tus yuam sij rau kev daws "adhesion" thiab "overheating" hauv titanium hlau kos duab. Kev lag luam feem ntau siv cov "roj-raws li lubrication + yuam kom txias" hom:

Roj-raws li lubricants (muaj cov khoom siv siab heev) tsim cov yeeb yaj kiab lubricating kom cais cov tuag ntawm qhov khoob, thiab cov khoom siv siab heev ua rau hnav- cov yeeb yaj kiab resistant nyob rau hauv qhov kub thiab txias;

Kev ua kom txias ua tiav tiag tiag -lub sij hawm kub txo los ntawm cov dej / roj, tswj qhov kub hauv qab ntawm titanium recrystallization kub kom tsis txhob muaj kev ua haujlwm degradation. Kev kho mob titanium hlau xav tau zaub mov-qib / kho mob- qib roj nplua nyeem kom ntseeg tau tias biocompatibility.

 

4. Txheej txheem Parameter Optimization

Lub hauv paus ntawm kev ua tiav "siab efficiency thiab tsawg noj" ntau lawm.

Qhov kev deformation dhau yuav tsum phim cov yas ntawm titanium cov ntaub ntawv: 15% -25% rau cov hlau titanium ntshiab hauv ib zaug, thiab txo mus rau 10% -18% rau titanium alloys xws li Gr5. Intermediate annealing yuav tsum tau nyob nruab nrab ntawm ntau qhov kev kos duab kom tshem tawm kev ua haujlwm nyuaj.

Cov duab nrawm raug xaiv raws li qhov xav tau: 1-5m / min qis ceev rau qhov kawg dhau kev ua tiav ntawm precision titanium hlau, thiab 10-30m / min kev kub ceev los txhim kho kev ua haujlwm ntawm cov duab ntxhib / nruab nrab daim duab (yuav tsum muaj zog lubrication thiab txias).

Lub nro yuav tsum tau tswj kom ruaj khov kom tsis txhob muaj txoj kab uas hla hloov pauv lossis xaim tawg.

 

III. Txheej txheem Optimization Directions thiab Core Applications

1. Cov txheej txheem ua kom zoo tshaj plaws cov lus qhia
