Txoj kev ncaj ncaj ntawm cov pas nrig hlau thiab titanium raj yog nro straightening, sinusoidal straightening, siab straightening, thiab lwm yam.
Tension straightening yog ib txoj hauv kev ua haujlwm uas siv lub zog tensile ntev tshaj qhov kev txwv ntawm cov khoom siv rau cov khoom ua haujlwm kom ua rau cov yas txuas ntxiv kom ua tiav cov kev kho qhov tsis xws luag, tseem hu ua kos duab straightening. Thaum lub sij hawm straightening, tensile kev nyuab siab tshaj qhov kev txwv ntawm cov khoom siv yog siv rau titanium pas nrig, titanium hlau, thiab titanium raj nrog yoj zoo tsis xws luag ntawm lub nro leveler. Lub tensile kev nyuaj siab yog superimposed nrog tus thawj residual kev nyuaj siab ntawm titanium bar. Ntawm qhov loj dua, ib feem ntawm tensile stress yog offset, kom qhov tseeb deformation kev nyuaj siab yog txo, thiab cov yas extension yog me me thaum lub sij hawm straightening; thaum nyob rau ntawm qhov qub txuas ntxiv, vim qhov nro ntawm Lub superposition ntawm kev ntxhov siab, qhov tseeb deformation ntawm kev ntxhov siab nce, thiab cov yas txuas ntxiv nce thaum lub sij hawm ncaj. Yog li ntawd, los ntawm qhov kev txiav txim ntawm qhov nro, txhua qhov chaw ntawm lub workpiece straightened txuas tusyees, thiab cov wavy defect yog li tshem tawm.
Hauv kev tsim khoom, sine straightening txoj kev yog dav siv rau cov pas nrig, cov xov hlau, thiab cov kav dej uas yooj yim hla ntu. Titanium tubes thiab rods yog tsim los ntawm inclined yob straightening tshuab. Tus naj npawb ntawm cov yob ntawm lub tshuab straightening yog ntau tshaj 4 (feem ntau 5 ~ 29 yob), thiab nws txoj kev ua haujlwm yog ua kom tsis tu ncua thiab pheej khoov lub workpiece los ntawm peb-taw tes dabtsi yog khoov ntawm txhua yob, yog li maj mam txo qhov sib txawv ntawm qhov seem. curvature ntawm lub workpiece.
Sinusoidal straightening feem ntau yog siv ua ke nrog lub siab ncaj. Ua ntej, lub workpiece nrog loj curvature yog straightened los ntawm lub siab straightening tshuab, thiab ces inclined roller straightening yog ua. Cov nyhuv straightening tsuas yog nyob ntawm lub siab ntawm lub straightener thiab inclination ntawm yob. Qhov loj ntawm lub siab nyob ntawm qhov tawm los lub zog thiab khoov ntawm cov khoom siv alloy. Yog hais tias nws yog ib tug high-strength titanium alloy thaum lub curvature loj, lub straightening siab yuav tsum loj, thiab vice versa. Qhov loj ntawm lub yob inclination lub kaum sab xis nyob ntawm txoj kab uas hla ntawm lub workpiece, thiab lub workpiece nrog ib tug loj txoj kab uas hla yuav tsum loj tshaj lub me me straightening inclination lub kaum sab xis. Tom qab straightening, lub workpiece tsis tsim nyog yuav tsum tau rov qab mus rau rov ncaj. Titanium tubes uas tsis tuaj yeem ncaj yuav tsum raug xa mus rau lub nro straightener rau straightening.
Lub hauv paus ntsiab lus ntawm roller straightening yog:
(1) Feem ntau, qhov me me ntawm cov yob txoj kab uas hla thiab ntau dua cov yob, qhov siab dua qhov tseeb; qhov me dua qhov kev ncua deb ntawm tus nqi yog, nws muaj txiaj ntsig zoo rau qhov tom ntawm lub workpiece thiab tsim cov txheej txheem ncaj.
(2) Lub luag haujlwm tseem ceeb ntawm thawj ob peb lub rollers ntawm cov menyuam ncaj yog txo qhov sib txawv ntawm qhov seem curvature ntawm workpiece raws qhov ntev kev taw qhia, thiab lub luag haujlwm tseem ceeb ntawm cov yob tom kawg yog txo qhov seem curvature kom nws zoo ib yam.
(3) Qhov zoo thiab qhov tsis zoo ntawm kev ua kom zoo yog nyob ntawm qhov kev txiav txim siab tsim nyog ntawm qhov rov qab curvature ntawm lub workpiece nyob rau hauv txhua tus menyuam. Nyob rau thawj ob peb yob (qhov thib ob thiab thib peb yob), qhov rov qab curvature loj yog xaiv, thiab qhov rov qab curvature ntawm cov rolls tom ntej yog txiav txim siab raws li qhov siab tshaj qhov seem curvature uas tuaj yeem ncaj nraim rau cov yob nyob ib sab pem hauv ntej.
(4) Qhov loj dua qhov hardening coefficient 7 yog, qhov nyuaj dua nws yog kom ncaj cov khoom. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tau xaiv qhov sib txawv ntawm qhov loj dua, cov yob ncaj dua, thiab lub voj voog me me.
