Dab tsi yog siv ntawm Q275?

Q275, ib nrab -- lub zog ua rau 275 MPa siab dua lossis muaj nuj nqis hauv lub zog, tus nqi qis, thiab cov khoom lag luam qis, thiab cov khoom lag luam qis. Hauv qab no yog nws cov ntawv thov tseem ceeb thiab cov xwm txheej tshwj xeeb:
1. Mechanical Raug
Cov Khoom Siv Hluav Taws Xob:
Haum rau kev tsim khoom lag luam uas yuav tsum tau tiv thaiv qee qhov kev tiv thaiv, xws li cov zog, cov nqaj hlau (cov pas nrig sib txuas, thiab pob zeb caj pas. Cov ntu no feem ntau siv los ua lub hauv paus cov khoom siv rau cov cuab yeej xws li cov cuab yeej siv lub tshuab, compressors, thiab twj.
Fasteners:
Nws tuaj yeem tsim cov fasteners xws li high - Lub zog, thiab cov tshuaj ntxuav kom haum rau lub zog (xws li kev nyab xeeb lub zog hauv cov khoom siv tshuab).
Stamping thiab sib sau seem:
Tom qab ua haujlwm txias (xws li txias dov thiab khoov), nws tuaj yeem tsim mus rau hauv cov rooj zaum uas yooj yim, thiab cov nkhaus, kom tau raws li kev txhawb nqa lossis kev ua haujlwm hauv cov neeg kho tshuab. Ii. Kev tsim kho thiab kev tsim kho vaj tse
Thauj - Cov kabmob:
Hauv kev tsim kho thiab engineering, cov khoom siv no tau siv los tsim cov me me thiab nruab nrab ntawm cov bearing nkhaus, kab teeb, txhawb nqa cov kab, thiab lwm yam. Lawv yog tsim nyog tshwj xeeb rau lub tsho hlau steel nrog cov qauv hluav taws xob nruab nrab (xws li pawg ua haujlwm nruab nrab thiab chaw khaws khoom lag luam khib nyiab khib).
Siv Machinery Accessories:
Cov txheej txheem sib xyaw ua ke siv hauv kev siv tshuab (xws li cranes thiab loaders), yuav tsum muaj ob qho tib si muaj zog thiab qee yam ntawm deformation tiv taus.
III. Tsheb thauj mus los thiab kev ua liaj ua teb
Lub tsheb tsheb:
Hauv qhov qis - ceev cov tsheb (xws li cov chaw ua liaj ua teb, thiab cov chaw sib sau ua ke, thiab cov chaw sib sau ua ke kom tau raws li kev tsav tsheb nruab nrab.
LAG LUAM MACHINERATION:
Haum rau load - Cov kabmob sib xyaw, xws li cov tsheb laij teb kev sib txuas, muaj peev xwm ntawm kev sib txuas lus thiab kev co ntawm cov hauj lwm.
IV. Lwm Cov Muaj Peev Xwm
Cuab Yeej thiab Pwm Accessories:
Yuav siv tau los tsim cov cuab yeej yooj yooj yim, pwm tsis tau load - Cov tub ntxhais siv lub zog los xyuas kom ntseeg tau cov qauv txheej txheem. Cov Khoom Hlau:
Siv rau hauv kev tsim cov khoom siab siab - Lub zog nthuav dav hlau, hlau guardrasts, thiab lwm yam kev siv, thiab lwm yam kev siv, thiab tsis kam ua.
Cov ntsiab lus ntawm kev thov cov yam ntxwv
Q275 feem ntau siv nyob rau hauv "nruab nrab {{1} ntim" Q235 (qis {{} lub zog), nws tuaj yeem tiv taus ntau dua cov rog. Txawm li cas los xij, piv rau Alloy qauv hlau (xws li 45 hlau thiab 20cr), nws tsis tshua muaj nqi thiab yooj yim dua tab sis muaj zog yuav tsum muaj cov kev xav tsis muaj tsawg. Txawm li cas los xij, vim nws cov pa roj carbon ntau (tsawg dua los yog sib npaug rau 0.29%), xws li preheating) yuav tsum ua tib zoo txiav txim siab kom tsis txhob tawg. Yog li ntawd, ua tib zoo tsim nyog rau nws siv hauv welded qauv.
