Dab tsi yog qhov txawv ntawm DC04 thiab SPCC?
DC04 thiab SPCC yog ob txoj kev siv dav dav ntawm txias - rolled steel ntawv, tab sis lawv txawv ntawm lawv cov khoom siv hlau, cov khoom siv txhua yam, thiab cov ntawv thov siv tau. Tus tub ntxhais sib txawv los ntawm lawv cov qauv sib txawv ua ntej: DC04 tsom rau kev muaj peev xwm nqus tau, thaum muaj spcc qhia txog kev ua haujlwm thoob ntiaj teb.
DC04: tob -} daim duab fility
Vim tias txhuas - tua, ua kom zoo dua li 80 hli (khob cij micriverently) Qhov no tso cai rau nws tiv thaiv:
Txoj kev sib sib zog nqus sib sib zog nqus (piv txwv li, lub qhov rooj vaj huam sib luag ntawm lub qhov rooj thiab lub tub luam hlav yees kab);
Thim rov qab kos duab thiab bulging (piv txwv li, tshwj xeeb {{2} zoo li cov ntoo hlau zoo li);
Ntau cov stamping deformations (tsis muaj kev pheej hmoo ntawm kev tawg). Spcc: General - lub hom phiaj muaj peev xwm
Coarse nplej (kwv yees li 20-30μm) thiab nruab nrab microstructure uniformity muab tsuas yog muaj formability (cupping Performance index ie ≈ 6.5mm). Cov khoom no tuaj yeem tiv thaiv:
Yooj yim stamping (piv txwv li, gaskets thiab nkhaus);
Ib Leeg -} theem dabtsi yog khoov thiab shearing (piv txwv li, hlau lub thawv);
Ua yam tsis muaj kev sib sib zog nqus daim duab (piv txwv li, ib yam dab neeg sib xws).
Nco tseg: Qhov siab dua IE, qhov ntau dua cov khoom sib sib zog nqus {{}}} kev muaj peev xwm. DC04's IE yog qhov siab dua SPCC's, ib qho tseem ceeb ntawm nws "tob {{}} kos duab" tsim.
