Q500NH Wights Hlaumuaj asiab dua los deform thaum uaPiv rau cov hlau me me vim nws lub zog siab (500 mpa yield) thiab qis dua lub zog, tab sis deformation tuaj yeem tswj tau nrog cov tswv yim zoo. Ntawm no yog phau ntawv qhia ncaj qha:
Vim li cas nws tus dhau mus deformation?
High Leput Zog: Yuav tsum muaj zog ntau dua los khoov / txiav, nce ntxiv kev ntxhov siab.
Qis elongation(~ 18% vs . 23}}% hauv Q235 steel) txo qis dua deformation muaj peev xwm.
Yuav ua li cas rau kev tswj deformation?
1. Txiav & Machining
Siv cov cuab yeej nruj: Carbide hniav los yog laser / ntshav txiav kom tsawg dua thaum tshav kub kub.
Clamp khov kho: Tiv thaiv kev co-indassing warping.
2. Dabtsi yog khoov thiab sib sau
TXIAS KHW: Txwv rau radii ntau dua lossis sib npaug2 × tuab tuab(piv txwv li, 20mm rau 10mm Phaj).
Dabtsi yog khoov(600-800 DEGREE) rau cov hluav taws xob nruj, ua raws li los ntawm qeeb cua txias.
3. VUAM
Preheat rau 150-200 degreethiab siv cov hluav taws xob tsawg-hydrogen kom txo qis shrinkage kev ntxhov siab.
Hloov Weld Ua Ntejkom sib npaug cov lus sov sov.
4. Kev ua dua tshiab
Kev ntxhov siab nyem: Cua sov mus rau 250-300℃(yog tias precision yog qhov tseem ceeb).
Mechanical Wiresening: Siv hydraulic presses, tsis kub.
