Piv nrog rau cov txheej txheem stamping ib txwm muaj, hydraulic forming tshuab muaj cov cuab yeej cuab tam thiab kev lag luam zoo hauv kev txo qhov hnyav, txo tus naj npawb ntawm cov khoom thiab pwm, txhim kho qhov nruj thiab lub zog, thiab txo cov nqi tsim khoom. Nws tau siv ntau dua hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam automotive.
Txo cov txheej txheem loj kom txuag tau lub zog thaum lub sijhawm ua haujlwm yog lub hom phiaj mus sij hawm ntev los ntawm cov neeg hauv kev lag luam tsheb, aviation, aerospace thiab lwm yam kev lag luam, thiab nws kuj yog ib qho ntawm cov qauv hauv kev tsim cov cuab yeej tsim khoom siab heev. Hydroforming yog ib qho kev tsim khoom siv thev naus laus zis txhawm rau ua tiav cov qauv teeb pom kev zoo.
Hydraulic forming, tseem hu ua "internal high-pressure forming", yog nyob rau hauv lub hauv paus ntsiab lus ntawm kev siv cov kav dej raws li billets, siv ultra-high pressure kua nyob rau hauv cov kav dej, thiab siv axial thrust rau ob kawg ntawm lub billets rau noj. Nyob rau hauv kev sib koom ua ke ntawm ob lub zog sab nraud, cov khoom siv billet undergoes yas deformation thiab thaum kawg adheres rau sab hauv phab ntsa ntawm pwm kab noj hniav, uas ua rau ib tug hollow ib feem uas ua tau raws li cov kev cai ntawm cov duab thiab raug.

Rau hollow variable cross-section structural Cheebtsam, cov tsoos manufacturing txheej txheem yuav tsum xub stamping ob halves thiab ces welding lawv mus rau hauv ib tug tag nrho, thaum hydraulic forming muaj peev xwm tsim hollow structural Cheebtsam nrog cov kev hloov nyob rau hauv lub cross-section nyob rau hauv ib tug mus. Piv nrog rau cov txheej txheem stamping thiab vuam, hydraulic txoj kev siv tshuab thiab cov txheej txheem muaj qhov zoo hauv qab no:
1. Txo qhov zoo thiab txuag cov ntaub ntawv. Rau cov khoom siv xws li tsheb cav thiab lub tshuab hluav taws xob, hydraulic tsim qhov txo qhov hnyav los ntawm 20% mus rau 40% piv rau cov khoom stamped; Rau qhov hollow stepped ncej, nws tuaj yeem txo qhov hnyav los ntawm 40% mus rau 50%.
2. Txo tus naj npawb ntawm cov khoom thiab pwm, thiab txo cov nqi pwm. Hydraulic tsim qhov feem ntau tsuas yog yuav tsum tau ib txheej pwm, thaum stamped qhov feem ntau xav tau ntau txheej pwm. Tus naj npawb ntawm hydraulic tsim cav bracket qhov chaw tau raug txo los ntawm 6 mus rau 1, thiab tus naj npawb ntawm radiator bracket qhov chaw tau raug txo los ntawm 17 mus rau 10.
3. Nws tuaj yeem txo qhov kev siv vuam uas yuav tsum tau ua rau kev ua haujlwm thiab kev sib dhos tom qab. Ua ib qho piv txwv ntawm lub radiator bracket, qhov kub dissipation cheeb tsam tau nce los ntawm 43%, tus naj npawb ntawm cov ntsiab lus vuam tau txo los ntawm 174 mus rau 20, cov txheej txheem txo los ntawm 13 mus rau 6, thiab cov khoom tsim tau nce 66%.
4. Txhim kho lub zog thiab nruj, tshwj xeeb tshaj yog lub zog qaug zog, xws li hydraulic tsim radiator brackets, nws qhov tawv tawv tuaj yeem nce 39% nyob rau hauv txoj kev ntsug thiab 50% nyob rau hauv txoj kab rov tav.
5. Txo cov nqi tsim khoom. Raws li kev txheeb cais ntawm hydraulic tsim qhov chaw uas tau thov, cov nqi tsim khoom ntawm hydraulic tsim cov khoom raug txo los ntawm qhov nruab nrab ntawm 15% mus rau 20% piv rau cov khoom stamped, thiab pwm tus nqi raug txo los ntawm 20% mus rau 30%.
