Txoj Kev Ncaj Ncees Seamless Titanium Tubes hauv Qib 2

Feem ntau siv txoj hauv kev ncaj rau titanium raj muaj xws li: nro straightening, sinusoidal straightening, thiab siab straightening.

Tension straightening yog ib txoj kev ua, tseem hu ua tensile straightening, uas siv ib tug ntsug nro mus rau lub workpiece uas tshaj qhov yield txwv ntawm cov khoom, uas ua rau plasticity prolongation thiab kho cov duab tsis xws luag. Thaum straightening, nro yog siv rau titanium rods, xov hlau thiab hlab nrog yoj zoo tsis xws luag ntawm lub nro straightening tshuab. Lub nro kev nyuaj siab accumulates nrog cov thawj residual kev nyuaj siab ntawm titanium rods. Nyob rau hauv qhov loj txuas ntxiv, ib feem ntawm tensile kev nyuaj siab tiv thaiv ib leeg, txo qhov tseeb deformation kev nyuaj siab, straightening plasticity extension yog me dua; nyob rau hauv thawj me me txuas ntxiv, vim lub tsub zuj zuj ntawm tensile kev nyuaj siab, lub deformation kev nyuaj siab yog tiag enlarged, straightening plasticity expansion. Yog li ntawd, nyob rau hauv nro, tag nrho cov seem ntawm lub workpiece straightened mus uniformly, tshem tawm cov shortcomings ntawm wavy zoo.

Sinusoidal straightening txoj kev yog dav siv nyob rau hauv zus tau tej cov yooj yim cross-section rods thiab nyob ntawm tej thiab hlab. Titanium raj thiab rods yog nqa tawm ntawm inclined roller straightening tshuab. Tus naj npawb ntawm cov yob ntawm lub tshuab ncaj yog ntau dua 4 (feem ntau 5 ~ 29 yob), thiab nws txoj haujlwm ua haujlwm yog khoov lub workpiece ntawm peb lub ntsiab lus sib law liag los ntawm txhua yob, maj mam txo qhov ntau ntawm cov kev hloov pauv ntawm qhov seem curvature ntawm workpiece. .

Sinusoidal straightening feem ntau yog siv ua ke nrog lub siab ncaj, uas yog cov workpieces nrog curvatures loj dua yog thawj zaug ncaj nraim los ntawm lub siab ncaj tshuab, thiab tom qab ntawd straightened los ntawm inclined yob. Cov nyhuv straightening feem ntau yog nyob ntawm lub siab straightener thiab yob inclination. Qhov loj ntawm lub siab nyob ntawm qhov tawm los lub zog thiab khoov qib ntawm cov khoom siv alloy. 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, me dua. Qhov luaj li cas ntawm yob inclination nyob ntawm txoj kab uas hla ntawm lub workpiece,, txoj kab uas hla ntawm lub workpiece yuav tsum loj tshaj qhov me me straightening inclination. 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.

Titanium tube rau cov menyuam straightening ntawm cov hauv paus ntsiab lus:

(1) qhov me me ntawm yob txoj kab uas hla, qhov ntau ntawm cov yob, qhov siab dua qhov tseeb; dov nrug yog me me, conducive rau lub workpiece tom thiab tsim ntawm cov txheej txheem straightening.

(2) titanium tube rau cov menyuam straightening lub luag haujlwm tseem ceeb ntawm thawj ob peb yob yog los txo qhov ntev ntawm lub workpiece raws li qhov seem curvature ntawm qhov sib txawv ntawm qhov tseem ceeb ntawm ob peb yob kawg yog txo cov seem curvature kom nws nyhav. ua ib yam.

(3) Qhov zoo ntawm kev ncaj nraim rau qhov tseem ceeb los txiav txim siab qhov zoo ntawm lub workpiece nyob rau hauv cov yob ntawm qhov kev tiv thaiv curvature. Thawj ob peb yob (qhov thib ob thiab thib peb yob) siv qhov loj los tiv thaiv curvature npaum li cas, cov rolls tom ntej ntawm kev tiv thaiv curvature yog raws li qhov seem curvature tuaj yeem ncaj nraim nyob ze ntawm lub hauv ntej yob los txiav txim.

(4) Qhov loj dua qhov hardening yam 7, qhov nyuaj dua nws yog kom ncaj cov khoom. Nyob rau ntawm lub sijhawm no, yuav tsum tau siv qhov kev khoov loj dua, cov yob ncaj dua thiab cov yob txoj kab uas hla me me yuav tsum tau siv.
