Yuav kom ntseeg tau qhov zoo ntawmforgingskom ua tau raws li qhov yuav tsum tau ua ntawm kev tsim thiab siv cov ntsuas ntsuas, nws yog ib qho tsim nyog yuav tsum tau uaforgings(dawb, semi-tiav khoom thiab cov khoom tiav) kev soj ntsuam zoo.
Cov ntsiab lus ntawm forgings zoo tshuaj ntsuam xyuas muaj xws li: tshuaj lom neeg muaj pes tsawg leeg tshuaj xyuas, zoo li thiab loj soj ntsuam, macroscopic lub koom haum soj ntsuam, microscopic lub koom haum tshuaj xyuas, txhua yam khoom tshuaj xyuas, residual kev nyuaj siab soj ntsuam thiab ultrasonic flaw detection.

1. Tshuaj lom neeg muaj pes tsawg leeg tshuaj ntsuam xyuas dav dav forgings tsis ua cov tshuaj muaj pes tsawg leeg tshuaj xyuas, tshuaj muaj pes tsawg leeg yog raws li smelting furnace sampling tsom xam. Tab sis rau qhov tseem ceeb lossis tsis txaus ntseeg forgings, qee cov chips tuaj yeem raug txiav los ntawm forgings thiab tshuaj ntsuam xyuas los yog kev soj ntsuam spectral yog siv los kuaj cov tshuaj muaj pes tsawg leeg.
2. Kev tshuaj xyuas qhov loj me uas siv kev tshuaj xyuas qhov muag, qauv lossis kev kos duab, tshawb xyuas forgings defects defects, zoo li qhov yuam kev thiab qhov loj me, los txiav txim seb lub forgings puas tuaj yeem ua machined.
3. macro lub koom haum kev soj ntsuam kuj tseem hu ua lub sij hawm tsis tshua muaj kev soj ntsuam, yog siv qhov muag liab qab los yog tsis ntau tshaj 10 npaug ntawm cov iav magnifying, xyuas qhov forging nto los yog seem ntawm lub koom haum macro. Cov txheej txheem tseem ceeb yog: sulfur printing, kub acid leaching, txias acid leaching thiab puas.
4. Kev tshuaj xyuas microstructure, uas yog kev kuaj xyuas metallographic, yog los soj ntsuam, txheeb xyuas thiab txheeb xyuas lub xeev microstructure thiab kev faib tawm ntawm forgings nyob rau hauv lub teeb tsom iav, thiaj li pab kom nkag siab txog kev sib raug zoo ntawm microstructure thiab forgings kev ua tau zoo.
5. Cov khoom siv kho tshuab tshawb xyuas cov khoom siv dav dav ntawm forgings, suav nrog kev kuaj xyuas hardness, txiav txim siab qhov ntsuas lub zog thiab cov ntsuas plasticity, cov ntsuas toughness, thiab lwm yam. , kev kuaj creep thiab qaug zog yuav tsum tau ua.
6. Residual stress check Nyob rau hauv lub forging ntau lawm txheej txheem, vim uneven deformation, uneven kub, uneven theem hloov yuav ua rau muaj kev ntxhov siab nyob rau hauv, thiab thaum kawg nyob rau hauv lub forging internal stress yog residual stress. Thaum muaj kev ntxhov siab ntau dhau nyob rau hauv lub forging, lub workpiece yuav deformed vim qhov poob ntawm qhov seem ntawm kev ntxhov siab thaum lub sij hawm machining, uas yuav cuam tshuam rau kev sib dhos. Thiab nyob rau hauv tus txheej txheem ntawm kev siv, vim hais tias ntawm residual kev nyuaj siab thiab ua hauj lwm kev nyuaj siab superposition yuav ua rau xoom tsis ua hauj lwm, thiaj li hais tias tag nrho cov tshuab puas. Yog li ntawd, cov txheej txheem ntawm qee qhov tseem ceeb forgings, xws li lub tshuab hluav taws xob tiv thaiv nplhaib, qhia tias qhov kev ntxhov siab seem yuav tsum tsis pub tshaj 20% ntawm lub zog tawm los.
Nyob rau hauv cov khoom soj ntsuam zoo saum toj no, xws li forgings tsos, tsis muaj zog, tsis pom kev kuaj cov khoom tsis tsim nyog yuav raug muab pov tseg. Yog tias cov khoom siv kho tshuab kuaj xyuas cov khoom tsis tsim nyog, lawv tuaj yeem rov ua dua. Yog tias lawv tseem tsis tsim nyog, lawv yuav tsum tau kho thiab rov kho dua. Rau kev forgings, tsuas yog xaiv ib lossis ob peb lub forgings los ntawm ib pawg lossis tib lub qhov cub rau kev tshuaj xyuas. Thiab rau qhov tseem ceeb forgings, xws li cov khoom siv fais fab nroj tsuag forgings, crankshafts loj, cov hlab ntsha siab, thiab lwm yam, txhua tus yuav tsum tau kuaj xyuas. Raws li forgings tshuaj xyuas ntawm cov khoom, yuav tsum ua raws li cov kev cai.
