Hlau ncej Castings

Peb txhawb kev tsim cov casting nrog peb yam khoom tseem ceeb, txhua tus haum rau qhov sib txawv ntawm daim ntawv thov scenarios thiab kev xav tau kev ua tau zoo, ua kom tus nqi zoo tshaj -kev ua tau zoo piv rau peb cov neeg siv khoom:

Cov pa roj carbon steel: Tus nqi- zoo, nrog rau kev ua haujlwm zoo thiab muaj zog txaus, haum rau tus qauv-load ncej, dav siv hauv kev lag luam tsheb chassis.

Alloy Steel: Lub zog tensile siab, cuam tshuam tsis kam, thiab qaug zog ua haujlwm, zoo tagnrho rau siab -load, hnyav ua haujlwm (xws li hnyav- tsheb thauj khoom, tsheb engineering), ua haujlwm tau zoo rau lub neej kev pabcuam.

Cov Hlau Hlau (Nodular Cam khwb cia hlau): Sib npaug lub zog thiab tawv, nrog kev poob siab zoo thiab hnav tsis kam, haum rau cov khoom uas xav tau kev ua haujlwm ruaj khov hauv kev ntxhov siab.

Peb cov thav duab castings npog tag nrho cov khoom hnyav - lub luag haujlwm tsheb chassis Cheebtsam, txhawb nqa ib qho - nres kev yuav khoom rau cov neeg siv khoom, suav nrog tab sis tsis txwv rau:

Thrust Rods: Ua kom lub tsheb ruaj khov ua haujlwm, tsis muaj lateral thiab longitudinal rog thaum tsav tsheb.

Nplooj Caij Nplooj Ntoos Hlav & Mounts: Dais lub tsheb hnyav, nqus txoj kev poob siab, thiab tswj kev tsav tsheb.

Fixing Brackets: Rau kev ruaj ntseg cav, kis tau tus mob, qag, thiab lwm yam khoom tseem ceeb, nrog rau qhov chaw siab.

Exhaust Pipes & Manifolds: High -kub tsis kam, corrosion kuj, ua kom cov pa tawm du thiab txo cov suab nrov.

Shock Absorber Brackets: Txuas kev poob siab absorbers rau lub thav duab, txhim khu kev vibration cais, thiab tiv thaiv chassis Cheebtsam.

Peb kuj lees txais customized casting ntau lawm raws li cov neeg siv khoom kos duab, cov qauv, thiab cov kev xav tau tshwj xeeb, suav nrog txhua hom ncej- ntsig txog castings rau cov tsheb loj.

Txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv ntawm cov khoom raws li ntau yam kev ua haujlwm, peb muab ntau yam kev pabcuam kev kho cua sov, suav nrog:

Annealing: Txo cov kev ntxhov siab sab hauv, txhim kho cov khoom toughness thiab machinability.

Quenching & Tempering: Txhim kho cov khoom siv zog, hardness, thiab hnav tsis kam, yoog rau siab -load Cheebtsam.

Normalizing: Kho cov qauv nplej, txhim kho cov khoom sib xws thiab cov khoom siv kho tshuab.

Peb cov txheej txheem kev kho cua sov yog tswj hwm nruj, ua raws li cov qauv thoob ntiaj teb, kom ntseeg tau tias kev ua tau zoo ntawm txhua qhov casting.

Txhawm rau txuas ntxiv kev pab cuam lub neej ntawm cov ncej castings nyob rau hauv ib puag ncig hnyav (xws li cov av noo, plua plav, thiab xeb), peb muab cov kev pabcuam nto tiv thaiv- xeb, suav nrog:

Kub-Dip Galvanizing: Zoo heev corrosion kuj, haum rau ntev - siv sab nraum zoov.

Electrophoretic Txheej: Uniform txheej, muaj zog adhesion, zoo tiv thaiv xeb thiab xeb.

Paint Spraying: Customizable xim, zoo nkauj zoo nkauj thiab tiv thaiv cov teebmeem, yoog raws cov neeg siv khoom sib txawv.

1.1 Khoom npe thiab daim ntawv thov

Cov khoom no yog ib qho kev sib xyaw ua ke cing (tom qab no hu ua "casting"), uas yog cov khoom tseem ceeb -cov kabmob tivthaiv rau ntau yam khoom siv tshuab (tsheb, siv tshuab, khoom siv tshwj xeeb, thiab lwm yam). feem ntau yog siv los txhawb lub powertrain, ncua kev kawm ntawv, thiab lub cev qauv. Los ntawm cov qauv tsim muaj xws li longitudinal thiab cross beams, nws ua tiav kev thauj mus los, kev ruaj khov, thiab kev tiv thaiv todeformation, ua haujlwm tseem ceeb hauv kev ua haujlwm kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv.

 

1.2 Cov yam ntxwv ntawm cov khoom

Txais cov qauv "Lu-zoo li" uas nyob rau hauv lub longim assemblies thiab cross beam assemblies (los yog raws li cov khoom tsim qauv piav qhia, xws li ib tug integrated tuag-casting qauv), txhim kho tag nrho cov qauv lub zog thiab torsional nruj thaum tsis txhob muaj kev ntxhov siab conion; Uniform phab ntsa thickness tsim, nrog rau cov cheeb tsam tseem ceeb txais yuav ib tug 3-8 hli gradient phab ntsa thickness (tshwj xeeb rau cov khoom kos duab), siv sloped transitions (txoj kab nqes tsawg dua los yog sib npaug rau 1: uce khoom tsub zuj zuj thiab txo cov kev pheej hmoo ntawm shrinkage kab noj hniav thiab porosity; Ribs teem raws cov kev taw qhia ntawm lub zog khiav, featuring variable variable dua los yog sib npaug zos rau 1. unloading grooves yog teem nyob rau hauv nruab nrab ntawm ntev tav los txhim kho tawg kuj thiab cov qauv yooj yooj yim;
