Tension straightening yog siv longitudinal nro rau lub workpiece tshaj qhov kev txwv ntawm cov khoom siv, thiaj li hais tias nws tsim cov yas txuas ntxiv kom ua tiav cov duab tsis xws luag, tseem hu ua kos duab straightening. Thaum straightening, lub tensile kev nyuaj siab tshaj qhov kev txwv ntawm cov khoom yog siv ua ntej thiab tom qab lub nro straightening tshuab rau titanium rods, nyob ntawm tej thiab cov hlab uas feem ntau muaj wavy zoo tsis xws luag. Lub tensile kev nyuaj siab yog superimposed nyob rau hauv lub qub residual kev nyuaj siab ntawm lub titanium bar, thiab nyob rau hauv lub residual kev nyuaj siab (piv txwv li tus thawj extension ntawm lub loj nthwv dej), ib feem ntawm lub tensile kev nyuaj siab yog muab tso tseg, thiaj li hais tias qhov tseeb deformation kev nyuaj siab yog txo, thiab yas extension yog me me thaum straightening. Nyob rau hauv lub residual tensile kev nyuaj siab (xws li lub extension yog me me), vim lub superposition ntawm tensile kev nyuaj siab, qhov tseeb deformation kev nyuaj siab nce, thiab cov yas extension yog loj thaum straightening. Raws li qhov tshwm sim, tom qab qhov nro straightening ntawm lub workpiece, tag nrho cov seem ntawm qhov txuas ntxiv ntawm lub teeb, wavy tsis xws luag yog li tshem tawm titanium raj, titanium bar straightening yog nqa tawm nyob rau hauv inclined yob hom straightening tshuab. Feem ntau siv ua ke nrog lub siab straightening, firstly lub workpieces nrog loj curvature yog straightened los ntawm lub siab straightening tshuab, thiab ces lub inclined yob hom straightening yog nqa tawm. Cov workpieces yuav tsum tau ncaj yog xa mus rau lub tshuab ncaj nraim thiab ncaj raws li nyob rau hauv ib theem tom qab hloov ntawm lub tshuab, thiab ib tug tom qab lwm yam. Qhov zoo ntawm straightening feem ntau yog nyob ntawm lub siab ntawm lub tshuab straightening thiab qhov loj ntawm lub yob inclination lub kaum sab xis. Qhov loj ntawm lub siab nyob ntawm seb hom alloy thiab qhov degree ntawm dabtsi yog khoov. Yog hais tias lub titanium alloy nrog lub zog siab thiab loj dabtsi yog khoov degree, lub straightening siab yuav tsum loj dua, thiab vice versa. Qhov luaj li cas ntawm tus pas qaij lub kaum sab xis nyob ntawm txoj kab uas hla ntawm lub workpiece, txoj kab uas hla ntawm lub workpiece yuav tsum loj dua qhov me me straightening qaij lub kaum sab xis. Straightening tseem yuav tsum tsis tsim nyog workpiece rov qab mus ncaj. Tsis tuaj yeem ncaj lub titanium raj yuav tsum raug xa mus rau qhov nro straightening tshuab straightening.
Kev tsim cov txheej txheem yooj yim ntawm cov khoom ua haujlwm yog siv dav hauv cov yob ntau dua 4 (feem ntau 5 ~ 29 yob) ntawm ntau cov yob ncaj. Nws txoj haujlwm ua haujlwm yog los ntawm cov yob ntawm lub workpiece tas mus li rov ua peb-point dabtsi yog khoov, yog li maj mam txo qhov ntau ntawm cov kev hloov pauv ntawm qhov seem curvature ntawm lub workpiece.
Lub hauv paus ntsiab lus ntawm roller straightening yog:
(1) Qhov me me ntawm txoj kab dav dav dav, qhov loj ntawm cov yob, qhov siab dua qhov tseeb; yob nrug 5 tus nqi yog me me yog qhov zoo rau qhov tom ntawm lub workpiece thiab tsim cov txheej txheem ncaj.
(2) Lub luag haujlwm tseem ceeb ntawm thawj ob peb yob yog txhawm rau txo qhov sib txawv ntawm qhov seem curvature ntawm lub workpiece raws qhov ntev kev taw qhia, thiab lub luag haujlwm tseem ceeb ntawm ob peb lub yob kawg yog los txo qhov seem curvature uas zoo ib yam.
(3) Qhov zoo ntawm straightening feem ntau yog nyob ntawm qhov tsim nyog txiav txim siab ntawm lub workpiece nyob rau hauv cov rolls ntawm anti-curvature tus nqi. Nyob rau hauv thawj ob peb yob (qhov thib ob thiab thib peb yob) ntawm qhov kev xaiv ntawm ib tug loj los tiv thaiv dabtsi yog khoov tus nqi, cov tom ntej rolls ntawm anti-curvature tus nqi tsuas yog kiag li ncaj nraim nyob rau hauv pem hauv ntej ntawm cov nyob sib ze yob ntawm lub siab tshaj plaws residual curvature los txiav txim.
(4) hardening coefficient ntawm 7 rau qhov loj ntawm cov khoom ncaj nraim yog qhov nyuaj dua, lub sij hawm no xaiv ib tug loj los tiv thaiv dabtsi yog khoov tus nqi thiab ntau straightening rolls thiab me me yob txoj kab uas hla.
