L profiles, U profiles, thiab square tube profiles tau dav siv vim lawv tuaj yeem txo qhov hnyav ntawm cov profiles thaum ua kom lawv lub zog. Tam sim no, cov cuab yeej siv thiab thev naus laus zis los tsim cov pa roj carbon steel thiab aluminium profiles yog cov paub tab. Ntawm lawv, ntau hom L thiab U profiles feem ntau suav nrog uncoiling, yob txoj kev, kev kho cua sov thiab txiav cov sawb coils ntawm yob dabtsi yog khoov cov cuab yeej, tom qab ntawd cov khoom sib thooj tau txais. Muaj ob hom kev tsim cov raj square, ib qho yog siv cov hlua khi hauv cov yob bending khoom rau de-coiling, yob txoj kev, vuam, ntxuav seams, kho cua sov, txiav, kom tau lub raj square; Lwm txoj hauv kev yog tsim cov raj puag ncig ncaj qha rau hauv lub raj square. Txawm li cas los xij, tsis muaj ib qho ntawm cov qauv tsim los saum toj no yuav tsum tau ua kom sov, thiab lawv yog cov txheej txheem ua haujlwm txias.
Nyob rau hauv xyoo tas los no, txhawm rau ua tiav lub hom phiaj ntawm kev txo qhov hnyav, lub cim tshiab ntawm huab cua, amphibious, unmanned thiab lwm lub teeb armored tsheb, xws li titanium thiab titanium alloy L-sections, U-sections thiab square tubes muaj qhov xav tau ceev. Txawm li cas los xij, titanium alloys nrog lub zog tawm los siab thiab ua haujlwm txias ua haujlwm yog qhov ua rau tawg thaum ua thiab molding. Yog tias cov cuab yeej tsim khoom uas twb muaj lawm los tsim cov pa roj carbon steel thiab aluminium profiles siv los tsim cov titanium alloy profiles, nws yuav ua rau tawg loj ntawm cov ces kaum ntawm cov profiles.
Tam sim no, txoj kev tsim cov titanium alloy nyias-walled L profiles thiab U profiles feem ntau yog lub phaj dabtsi yog khoov txoj kev, tshwj xeeb tshaj yog: lub phaj yog rhuab nyob rau hauv ib tug atmospheric rauv, thiab ces khoov thiab tsim nrog kev pab los ntawm ib tug pwm ntawm ib tug xovxwm. Cov teeb meem ntawm txoj kev no yog: 1) lub sijhawm cua sov yog qhov ntev, qhov chaw ntawm lub phaj yog oxidized tiag, uas ua rau muaj teeb meem rau kev kho deg; 2) kev sib cuag ntawm lub phaj rhuab nrog pwm txias thaum lub sij hawm molding txheej txheem yuav ua rau lub kub ntawm lub phaj poob sharply, uas yuav ua rau lub kub kub thaum lub sij hawm molding, thiab cov profiles yuav tawg; 3) qhov tseeb ntawm qhov profile (dav, qhov siab, thiab R-lub kaum sab xis), thiab qhov ncaj yog qhov tsis zoo. Kev tsim cov titanium alloy nyias-walled square tube txoj kev yog feem ntau phaj dabtsi yog khoov + vuam txoj kev, pwm kev kos duab, kub dov thiab lwm yam. Ntawm lawv, phaj dabtsi yog khoov + welding txoj kev tuaj yeem npaj titanium alloy square raj, tab sis vim muaj cov welded seams, kom lub neej ntawm lub raj txo qis heev. Txoj kev tuag tuag vim yog titanium alloy deformation tsis kam, nws yog ib qho nyuaj rau tsim los ntawm qhov loj deformation tus nqi ntawm daim duab, feem ntau xav tau ntau tshaj ib daim duab molding, ntau lawm lub voj voog ntev, thiab cov txheej txheem kos duab yuav tsum tau rhuab, uas yuav ua rau titanium. alloy thiab pwm yog ib qho yooj yim los tsim kev sib txuas ntawm lub raj rau hauv cov khoom siv tsawg. Suav patent CN105903766A qhia txog kev siv cov kub dov los ncaj qha npaj titanium alloy square raj, tab sis qhov tseeb qhov tseeb ntawm lub raj square yog pluag; Suav patent CN110369548A tau tshaj tawm kev siv cov titanium alloy yeeb nkab ua ib lub raj, lub raj puag ncig yog rhuab ua ntej lub raj puag ncig mus rau square raj molding, round raj rau square raj ua ntej cua sov ua rau cov titanium alloy sab hauv thiab sab nraud ntawm qhov loj oxidation. , thiab tom qab siv polishing kev kho mob, square polishing taub hau tsis tuaj yeem siv rau hauv lub raj square, lub square polishing taub hau tsis tuaj yeem siv rau hauv lub raj square. Lub taub hau square polishing tsis tuaj yeem tig rau hauv lub raj square, thiab lub taub hau polishing puag ncig tsis tuaj yeem tshem tawm cov tawv nqaij oxidized ntawm sab hauv ntawm lub raj square. Ntxiv mus, lub rhuab raj yuav ua rau thermal puas rau molding rollers.
Hauv cov ntsiab lus, cov txheej txheem tam sim no rau kev npaj nyias-walled profiles ntawm titanium alloy muaj teeb meem ntawm kev molding tsis zoo, kev ua haujlwm nyuaj, thiab kev kho deg nyuaj.
Nyob rau hauv kev pom ntawm no, tam sim no invention muab ib txoj kev ntawm kev npaj ib tug titanium alloy molded ib feem thiab ib txoj kev ntawm kev npaj ib tug titanium alloy nyias-walled profile. Cov txheej txheem muab los ntawm qhov kev tsim kho tam sim no tuaj yeem txhim kho qhov tsim ntawm titanium alloy nyias-walled profile thaum npaj cov titanium alloy molded ib feem, thiab txo qhov nyuaj ntawm nws cov txheej txheem thiab kev kho deg.
Tam sim no invention muab ib txoj kev ntawm kev npaj ib tug titanium alloy tsim ib feem, muaj xws li cov nram qab no cov kauj ruam: ib tug titanium alloy billet yog yob-tsim nyob rau hauv ntau yam passes kom tau ib tug tsim ib feem, thiab cua sov yog ua thaum lub sij hawm hais ntau dhau ntawm yob-forming; hais tias dhau ntawm yob-forming yog los ntawm 7 mus rau 13; hais tias cua sov muaj xws li: thaum tus naj npawb ntawm molding pass yog ib tug txawm tus naj npawb ntawm passes N, ces pib los ntawm lub (N/2) th pass ntawm molding pass, thiab ua cua sov tom qab molding ntawm txhua pass; thaum tus naj npawb ntawm molding dhau yog ib qho khib ntawm qhov N, ces ua cua sov tom qab molding ntawm txhua qhov dhau; Thaum tus naj npawb ntawm molding dhau yog ib qho khib tus lej ntawm N, ces ua kom sov tom qab molding ntawm titanium alloy yog ua. cua sov; Thaum tus naj npawb ntawm molding racks yog tus lej M, ces pib ntawm (M+1) / 2nd khib ntawm molding racks, txhua khib yog rhuab tom qab molding. Qhov kev tsim kho tam sim no tuaj yeem txo qhov deformation ntawm titanium alloy billet thaum lub sij hawm molding txheej txheem los ntawm kev teeb tsa tus naj npawb tsim nyog ntawm molding racks, thiab tiv thaiv cov titanium alloy billet los ntawm kev tawg vim muaj kev kub ntxhov deformation. Tam sim no invention kuj heats lub titanium alloy billet tom qab txhua racking nyob rau hauv nruab nrab thiab rear seem ntawm cov khoom molding, thiab heats lub titanium alloy billet thaum lub sij hawm loj deformation nyob rau hauv nruab nrab thiab nram qab seem, uas txo cov kev nyuaj ntawm titanium alloy, ntxiv tiv thaiv cov titanium alloy billet los ntawm kev tawg thaum lub sij hawm molding txheej txheem, thiab txhim kho qhov ntev precision ntawm molded qhov chaw thiab cov yield tus nqi, thiab nyob rau tib lub sij hawm, vim hais tias cov cua sov ntaus ntawv yog teem nyob rau hauv nruab nrab thiab rear seem ntawm molding. txheej txheem, tsis tas yuav tsum tau ua kom sov lub billet ntawm qhov kub thiab txias ua ntej lub billet yog pub rau hauv cov khoom molding, thiab cov cua kub ntawm qhov khoob yog txo. Lub thermal puas ntawm qhov kub-kub dawb paug rau tag nrho cov conveyed qhov chaw nyob rau hauv lub molding khoom yog txo, uas yog conducive rau kev txhim kho lub neej ntawm cov khoom molding.
Tam sim no invention kuj muab ib txoj kev ntawm kev npaj ib tug titanium alloy nyias-walled profile, uas yuav siv tau los npaj ib tug nyias-walled profile nrog ib tug phab ntsa thickness tsawg dua los yog sib npaug zos rau 6 hli los ntawm tshav kub-kho, shaping, straightening thiab nto kho. ntawm cov molded qhov chaw nyob rau hauv cov kev daws teeb meem saum toj no.
