Casting Tolerances los ntawm txawv Casting txheej txheem

Dimensional kam rau ua yog ib qho tseem ceeb thaum peb xaiv cov txheej txheem casting rau qhov xav tau castings. Nyob rau hauv ISO 8062 (suav nrog Tuam Tshoj tus GB / T6414-1999) cov ntaub ntawv txheem, cov qib siab kam rau ua qhov loj me tau qhia meej meej. Feem ntau hais lus, kev nqis peev casting thiab tuag casting muaj qhov raug siab nyob rau hauv qhov ntev thiab yog vim li cas cov txheej txheem peev casting kuj hu uaprecision casting. Ntawm no hauv qab no koj yuav pom cov kev kam rau siab ntawm castings los ntawm cov txheej txheem casting sib txawv.

Casting Tolerances rauXuab zeb Castings

Cov kev kam rau ua tau muab faib ua Dimensional Casting Tolerances (DCT) thiab Geometrical Casting Tolerances (GCT). Peb lub tuam txhab xav tham nrog koj yog tias koj muaj kev thov tshwj xeeb ntawm qhov yuav tsum tau ua. Ntawm no nyob rau hauv cov nram qab no yog cov kev tolerances qib peb tuaj yeem ncav cuag los ntawm peb cov xuab zeb ntsuab, plhaub pwm casting thiab tsis muaj ci furan resin xuab zeb casting:

• ✔ DCT Qib los ntawm Green Sand Casting: CTG10 ~ CTG13
• ✔ DCT Qib los ntawm Plhaub Pwm Casting lossis Furan Resin Sand Casting: CTG8 ~ CTG12
• ✔ GCT Qib los ntawm Green Sand Casting: CTG6 ~ CTG8
• ✔ GCT Qib los ntawm Plhaub Pwm Casting lossis Furan Resin Sand Casting: CTG4 ~ CTG7

 

Casting Tolerances rauKev nqis peev Castings

Raws li cov ntaub ntawv sib txawv siv los ua lub plhaub, cov peev txheej tuaj yeem muab faib ua silica sol casting thiab dej iav casting. silica sol peev txheej txheej txheem casting muaj qhov zoo dua Dimensional Casting Tolerances (DCT) thiab Geometrical Casting Tolerances (GCT) dua li cov txheej txheem iav dej. Txawm li cas los xij, txawm tias los ntawm tib txheej txheem casting, Qib Siab Siab yuav txawv ntawm txhua qhov cam khwb cia hlau vim lawv ntau yam castability. Peb lub tuam txhab xav tham nrog koj yog tias koj muaj kev thov tshwj xeeb ntawm qhov yuav tsum tau ua. Ntawm no yog cov hauv qab no yog cov qib tolerances uas peb tuaj yeem ncav cuag ob qho tib si los ntawm silica sol casting thiab dej iav casting txheej txheem cais:

• ✔ DCT Qib los ntawm Silica Sol Lost Wax Casting: DCTG4 ~ DCTG6
• ✔ DCT Qib los ntawm Dej iav Poob Wax Casting: DCTG5 ~ DCTG9
• ✔ GCT Qib los ntawm Silica Solt Wax Casting: GCTG3 ~ GCTG5
• ✔ GCT Qib los ntawm Dej iav Poob Wax Casting: GCTG3 ~ GCTG5

 

Casting Tolerances rau Plhaub Pwm Castings

Raws li peb tau hais nyob rau hauv lub siab kam rau ua rau cov xuab zeb castings, lub plhaub pwm castings muaj ntau dua qhov tseeb thiab nruj dua kam rau ua dua xuab zeb casting. Ntawm no yog cov hauv qab no yog cov qib tolerances uas peb tuaj yeem ncav cuag los ntawm peb lub plhaub pwm casting thiab tsis muaj ci furan resin xuab zeb casting:

• ✔ DCT Qib los ntawm Plhaub Pwm Casting lossis Furan Resin Sand Casting: CTG8 ~ CTG12
• ✔ GCT Qib los ntawm Plhaub Pwm Casting lossis Furan Resin Sand Casting: CTG4 ~ CTG7

 

Casting Tolerances rau Poob Foam Castings

Feem ntau hais lus, qhov kev ua siab ntev ntawm kev poob ua npuas ncauj yog zoo dua li cov xuab zeb casting, tab sis phem dua li lub plhaub pwm casting thiab cov txheej txheem tsis muaj ci. Rau peb cov foundry, peb yeej tuaj yeem ua tiav cov qib casting nram qab no. Tab sis peb xav nrog koj tham txog qhov tshwj xeeb castings thiab tom qab ntawd txiav txim siab seb tus lej twg peb tuaj yeem muab rau koj.

• ✔ DCT Qib los ntawm Poob Foam Casting: CTG9 ~ CTG13
• ✔ GCT Qib los ntawm Poob Foam Casting: CTG5 ~ CTG8

Yog tias daim duab kos duab lossis cov txheej txheem casting kom meej meej yuav tsum tau kuaj xyuas tag nrho qhov ntev ntawm qhov casting, tag nrho cov qhov ntev ntawm qhov casting yuav tsum tau kuaj xyuas. Qhov xwm txheej no feem ntau yog thawj feem ntawm kev tsim cov castings los yog cov txheej txheem kev soj ntsuam random thaum lub sij hawm ntau lawm. Hauv kev tsim khoom me me, qee zaum yuav tsum tau kuaj xyuas txhua qhov loj ntawm qhov casting.

Raws li cov kev cai uas tau teev tseg hauv cov duab kos lossis cov ntaub ntawv txheej txheem, qhov ntev ntawm cov castings yuav tsum tau kuaj xyuas qhov tseem ceeb ntawm qhov loj me, qhov loj me nrog cov kev xav tau siab, thiab qhov ntev uas yooj yim deformed thiab tawm ntawm qhov ntev. Qhov teeb meem no feem ntau yog siv rau kev tswj xyuas qhov ntev ntawm cov khoom loj ntawm cov kab ntau lawm.
