Tsheb Tsau Torque Qws Dej iav Investment Casting

Khoom Taw Qhia

Lub torsion bar ntawm lub rear qag ntawm lub tsheb yog siv los txo cov yob ntawm lub tsheb thaum tig thiab txhim kho kev caij tsheb:
1. Lub torsion bar siv cov tshuaj tiv thaiv tsim los ntawm lub zog ntawm tus pas nrig kom sab laug thiab sab xis ntawm lub tsheb ntawm qhov siab zoo sib xws kom tsis txhob tilting. Feem ntau cov kev ncua ntawm lub tsheb me me mus rau cov tsheb thauj khoom hnyav yog nruab nrog cov tuav ruaj khov. Vim qhov xav tau kom tsis txhob muaj lwm cov khoom nyob ib puag ncig thaum tsim, stabilizer tuav tuaj nyob rau hauv ntau yam ntaub ntawv, tab sis lawv yeej nyob rau hauv cov duab ntawm ib tug torsion bar; 2. Cov kev tiv thaiv yob los ntawm lub torsion bar thiab springs ntxiv rau ib leeg, thiab kev tiv thaiv yob lawv tshwm sim ua khub, uas yog hais tias, kev tiv thaiv yob nyob rau pem hauv ntej ntawm lub tsheb yog nrog los ntawm kev tiv thaiv. -roll resistance nyob rau hauv qab. Txawm li cas los xij, vim qhov hnyav piv ntawm lub cev ntawm lub tsheb thiab cov teebmeem ntawm lwm cov quab yuam sab nraud, qhov kev tiv thaiv yob ntawm lub hauv ntej thiab nram qab yog tsis sib npaug, yog li thaum nws los txog, nws yuav cuam tshuam ncaj qha rau kev hloov ntawm lub cev qhov hnyav thiab qhov sib npaug ntawm tuav;
2. Lub hardness ntawm Automobile tsau torque pas nrig dej iav peev casting yog txiav txim los ntawm cov khoom, ncej, pas nrig txoj kab uas hla, ntev ntawm tus pas nrig caj npab thiab lub kaum sab xis nrog lub ncej. Qhov ntev ntawm tus ncej, qhov softer lub hardness, thiab conversely, qhov ntev ntawm caj npab, qhov nyuaj nws yuav.
 

Dej iav Casting txheej txheem
1. Txoj kev qhuav
(1) Sodium carbonate txoj kev: Raws li cov qauv kev xav tau ntawm cov khoom yuav tsum tau, sib tov dej qab zib tshauv (Na2CO3) thiab quartz xuab zeb (SiO2) nrog ib qho me me ntawm 0.180 ~ 0.250 mm ( 60 ~ 80 mesh) nyob rau hauv kev faib ua feem thiab tusyees xa mus rau lub horseshoe nplaim kiln, melted ntawm 1450 ~ 1500 degree, cov khoom kub-kub molten ntws tawm ntawm lub qhov hluav taws xob, thiab nias rau hauv blocks los ntawm chais rau ntawm pwm los yog quenched. nrog dej rau hauv cov khoom.
(2) Yuanming hmoov (tseem hu ua sodium sulfate, anhydrous Glauber's ntsev) txoj kev: Cov ntaub ntawv raw muaj xws li sodium sulfate (anhydrous Glauber's ntsev), carbon hmoov, thiab quartz xuab zeb. Cov txheej txheem ntau lawm yog tib yam li cov txheej txheem sodium carbonate, tshwj tsis yog tias qhov tsis zoo siab yog siv rau hauv qhov cub. Kev ua haujlwm, tso pa tawm tom qab lub qhov cub.
(3) Sodium chloride method: Siv sodium chloride (NaCl) thiab quartz xuab zeb ua raw cov ntaub ntawv, sib tov quartz xuab zeb thiab sodium chloride tusyees thiab yaj lawv, ntxiv chav, thiab hnov ​​mob kom tau sodium silicate thiab hydrochloric acid. Txoj kev no muaj cov tshuaj tiv thaiv qeeb qeeb thiab tsis nquag siv hauv cov chaw ua haujlwm.
2. Txoj kev ntub dej
Sib tov kua sodium hydroxide thiab quartz xuab zeb nyob rau hauv ib qho kev faib ua feem thiab ntxiv rau lub autoclave, tshav kub thiab do nrog chav kom react ncaj qha rau cov kua sodium silicate, uas yog lim thiab concentrated kom tau tiav dej iav. Txoj kev ntub dej tsuas tuaj yeem tsim cov khoom lag luam nrog cov qauv qis dua 2.5, nws yog qhov nyuaj rau kev tsim cov khoom siv nrog cov modulus siab, thiab cov tshuaj tiv thaiv ceev qeeb, uas txwv tsis pub siv cov qauv no. kuv lub teb chaws cov khoom ntub dej ntawm cov kua sodium silicate tsuas yog 5% ntawm tag nrho cov khoom tsim tawm hauv lub tebchaws.
