Yuav ua li cas nrum lub siab - zoo crankshaft? - Ua tiav cov ntawv qhia ua tiav
May 30, 2025| 1. Cov khoom xaiv: "DNA" ntawm koj crankshaft
Cov khoom txiav txim siab rau crankshaft'sLub zog, hnav tsis kam, thiab qaug zog lub neejCov. Cov kev xaiv sib xws muaj xws li:
Coo cov hlau (qt700-2, Qt800-2)- Nqis, zoo tagnrho rau cov qauv tsheb yam lag luam.
Forged Hlau (42CRMO4, 38MNVS6)- Lub zog siab dua, siv nyob rau hauv high -}} Cov cav.
Compacted Graphite Hlau (CGI)- Sib koom cov khoom cam thiab cov txiaj ntsig hlau, feem ntau hauv cov cav diesel.
Pib qhia:
Rau cov cav me me (maus taus, nyiaj txiag tsheb),QT700-2 Zas Hlauis cost-effective.
Rau kev sib tw lossis hloov kho cov cav,42Crmo4 Forged Hlaumuaj cov neeg qaug zog zoo dua.
2. Cov txheej txheem casting: Tsim cov crankshaft "ntawm pob txha"
Sandal Xoom Casting (zoo tshaj plaws rau cov hlau ductab)
Cov kauj ruam:
Tsim ib tsob ntoo lossis 3D -} cov qauv luam tawm.
Ua ib xuab zeb pwm (silica sand + binder).
Ncuav molten hlau (1350-1450 degree).
Txias, tshem tawm, thiab ntxuav cov ntxhib casting.
✅ Pros:Tus nqi qis, zoo rau huab hwm coj ntau lawm.
❌ Cons:Ntxhib saum npoo, yuav tsum tau machining.
Kev nqis peev Casting (txoj kev precision)
Siv ib lub tshuab ua yeeb yam me me coated hauv ceramic slurry, melted deb ua ntej hlau pouring.
✅ Pros:Siab precision, du tas.
❌ Cons:Kim, zoo dua rau me me batches.
Cov Lus Pom Zoo:
Pib nrogxuab zeb casting{{0 {}} Nws yooj yim dua thiab pheej yig dua.
Rau siab - precision cranks, outsource rau ib tug kws tshaj lij.
3. Kev kho cua sov: ntxiv dag zog rau crankshaft
Cov cuab yeej nyoos feem ntau muaj kev ntxhov siab sab hauv thiab cov qauv tsis ncaj. Kev Kho Cua Sov yogtseem ceebrau durability.
✔ Li caserizing (rau cov hlau ductab)
Ua kom sov rau 900 degree, tuav rau 2 teev, ces huab cua - txias.
🔹 Cov nyhuv:Refines cov qauv grain, txhim kho kev nruj.
Quenching & Tempering (rau forged steel)
Quench:Thaum tshav kub kub rau 850 degree, ces roj - txias rau lub hardness.
Temper:Rov ua dua kom rov ua kom 550 degree, huab cua - txias kom txo brittleness.
Pib qhia:
Tsis txhob mus hla kev kho cua sov!Tsis tau kho crankshafts tuaj yeem tawg raws kev ntxhov siab.
4. Machining: Precision Tiav
Cov cuab yeej siv ntxhib yuav tsum yogMachined rau cov specifications tshwj xeebua ntej siv.
Key Machine Machine:
Txoj siav- CNC tshuab dhos ua haujlwm los ua cov kev lom zem (kev sib tw tsis pub dhau 0.01 hli).
Kev sib tsoo- High {- Precision sib tsoo rau cov chaw du (ra tsawg dua lossis sib npaug rau 0.4μm).
Kev drilling- Cov nqe vaj lug yuav tsum tau ua kom muaj lubrication.
Kev ntsuas kev sib npaug- Cov lus tsis txaus yuav tsum yogTsawg dua los yog sib npaug rau 15 GIN CAPkom tiv thaiv kev sib tw.
Cov lus qhia pib:
Yog tias koj tsis muaj nuj nqis precision,Ntiav Ib Lub Tshuab Khw.
Kev ntsuas tsis yog qhov tsis - kev sib ceg{{0-} Tsis muaj cranks ua rau lub cev puas tsuaj!
5. Kev tshuaj xyuas zoo: ua kom muaj kev cia siab
✔ Sib Nqus Particetting (cov nrib pleb cov kab nrib pleb)
Kuaj cov kab tsuag me me siv cov sib nqus sib nqus.
✔ Kev Ntsuam Xyuas Ultrasonic (Sab Hauv Txhab Tsis Txaus)
Kev txheeb xyuas rau Voids / suav nrog rau kev sib xyaw hlau cranks.
✔ Kuaj Kev Ua Kom Zoo
Das Hlau:HRC 22-28| Forged Hlau:HRC 30-35.
Pib yuav tsum -} ua:
Tsawg kawg, uaSib Nqus Particle Soj Ntsuamkom tsis txhob tawg.
Cov ntsiab lus kawg: Tus Crankshaft casting txheej txheem
1. Xaiv cov khoom siv → 2. Khoom puab hlau → 3. Cua Sov Kho → 4. Lub tshuab → 5. Kuaj xyuas
