Dab tsi yog cov qauv coj ua rau SPCD yob?
A: Feem ntau ua raws li Japanese Industrial Standard JIS G3141, tab sis kuj tau sib xws nrog ntau tus qauv thoob ntiaj teb xws li AISI thiab ASTM, ua tau raws li qhov xav tau ntawm kev yuav khoom thiab kev tsim khoom ntawm ntau cheeb tsam.
Dab tsi yog cov khoom tseem ceeb ntawm SPCD yob?
A: Nws belongs rau qis- carbon txias- dov steel, nrog nruj me ntsis txwv cov ntsiab lus: carbon Tsawg dua lossis sib npaug li 0.10%, manganese Tsawg dua lossis sib npaug li 0.50%, phosphorus Tsawg dua lossis sib npaug rau 0.040%, sulfur Tsawg dua lossis sib npaug rau 0.035%. lossis 20%. Tsawg impurity cov ntsiab lus kom nws cov stamping kev ua tau zoo.
Dab tsi yog qhov txawv ntawm SPCD yob thiab SPCC yob?
A: Ob leeg yog txias -rolled steel rolls. SPCD yog tsim los rau stamping, nrog ib tug purer muaj pes tsawg leeg thiab zoo plasticity; SPCC yog dav dav -lub hom phiaj txias- dov steel nrog tsis muaj zog stamping kev ua tau zoo. Lub qub yog tsim rau nruab nrab -deformation stamping qhov chaw, thaum lub tom kawg yog feem ntau yog siv rau yooj yim dabtsi yog khoov, zoo tib yam plhaub, thiab lwm yam tsawg - daim ntawv thov.
Dab tsi yog cov qib nto ntawm SPCD yob?
A: Muab faib ua peb pawg: FB, FC, thiab FD. FB yog tsim rau kev stamping dav, FC yog haum rau complex stamped qhov chaw, thiab FD yog rau siab -precision sib sib zog nqus- kos qhov chaw. Cov qib sib txawv sib txawv raws li qhov yuav tsum tau ua kom raug.
Dab tsi yog qhov kev qhia tshwj xeeb ntawm SPCD yob?
Teb: Qhov dav feem ntau yog nyob nruab nrab ntawm 45-2200mm, lub thickness feem ntau yog 0.2-4mm (tus qauv thickness ntau yam rau txias dov yob), thiab qhov ntev tuaj yeem kho raws li cov neeg siv khoom xav tau los hloov kho raws li qhov yuav tsum tau ua ntawm cov khoom sib txawv.
