S890QL quenched thiab tempered qauv hlau
Kub-Forming
Kub-forming saum 580 ° C yog ua tau. Tom qab quenching thiab tempering yuav tsum tau ua raws li cov kev cai ntawm kev xa khoom.
Milling
Drilling nrog cobalt-alloyed high-speed steels HSSCO. Txiav ceev yuav tsum yog kwv yees li 17 - 19 m / / min. Yog tias siv HSS xyaum, txiav ceev yuav tsum yog kwv yees li 3 - 5 m / / min.
Nplaim-txiav
Qhov kub ntawm cov khoom yuav tsum yog tsawg kawg yog RT rau nplaim taws. Tsis tas li ntawd, qhov ntsuas kub hauv qab no tau pom zoo rau qee cov phaj thicknesses: Rau phaj thicknesses tshaj 40mm, preheat rau 100 ° C thiab rau thicknesses tshaj 80mm, preheat rau 150 ° C.
Vuam
S890QL steel yog tsim rau txhua txoj kev vuam tam sim no. Qhov kub ntawm cov khoom yuav tsum yog tsawg kawg yog RT rau vuam. Tsis tas li ntawd, cov nram qab no preheating kub yog pom zoo rau tej phaj thicknesses:
20mm-40mm: 75 ° C
Tshaj 40mm: 100 ° C
60mm thiab tshaj: 150 ° C
Cov kev taw qhia no yog tus qauv tsim nyog nkaus xwb, hauv paus ntsiab lus, kev qhia ntawm SEW 088 yuav tsum tau ua raws li.
Lub t 8 / 5 zaug yuav tsum nyob nruab nrab ntawm 5 thiab 25 s, nyob ntawm seb cov txheej txheem vuam siv. Yuav tsum muaj kev ntxhov siab rau kev tshem tawm qhov tsim nyog rau kev tsim kho, qhov no yuav tsum tau ua nyob rau hauv qhov kub ntawm 530 ° C-580 ° C.
