Yuav txheeb xyuas qhov zoo ntawm Forging li cas

Forging yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom siv los tsim cov khoom siv nrog lub zog siab, kev qaug zog zoo heev, thiab kev ntseeg tau ntawm cov qauv. Txawm li cas los xij, tsis yog tag nrho cov forged Cheebtsam yog tsim sib npaug. Kev txheeb xyuas qhovzoo forgingNws yog ib qho tseem ceeb los xyuas kom meej kev nyab xeeb, kev ua tau zoo, thiab ua raws li cov qauv thoob ntiaj teb - tshwj xeeb hauv kev lag luam xws li aerospace, tsheb, roj thiab roj, lub zog, thiab cov tshuab hnyav.

Hauv tsab xov xwm no, peb muab cov lus qhia ua tiav ntawm kev txheeb xyuas qhov zoo ntawm forgings. Los ntawm kev tshuaj xyuas qhov muag mus rau qhov kev sim siab tsis muaj kev puas tsuaj thiab kev lees paub kev lees paub, daim ntawv xov xwm SEO no qhia txog cov tswv yim zoo rau kev lees paub zoo. Txawm hais tias koj yog ib tus neeg yuav khoom, tus kws tshaj lij, lossis tus kws tshuaj ntsuam xyuas, kev nkag siab yuav ua li cas ntsuas cov khoom forged yuav pab koj txiav txim siab zoo dua.

Yog vim li cas Quality Matters hauv Forging

Forged Cheebtsam yog feem ntau siv nyob rau hauvload-bearing, siab, thiabkub kubib puag ncig. Forgings tsis zoo los yog substandard forgings tuaj yeem ua rau:

  • Cov khoom siv tsis ua haujlwm

  • Kev nyab xeeb

  • Ntau lawm downtime

  • Tus nqi rov qab

Xyuas kom forging zoo tiv thaiv koj lub lag luam thiab cov neeg siv kawg. Tias yog vim li cas cov neeg muab khoom lag luam nyiamsakysteel uasiv cov txheej txheem tswj xyuas kom zoo los ntawm kev xaiv cov khoom siv raw mus rau kev tshuaj xyuas zaum kawg.

1. Kev tshuaj xyuas qhov muag

Thawj kauj ruam hauv kev txheeb xyuas qhov zoo ntawm forging yog ua tib zoo saib xyuas. Ib tus kws tshuaj ntsuam xyuas tuaj yeem kuaj xyuas qhov tsis zoo ntawm qhov chaw uas yuav qhia tau tias muaj teeb meem loj dua.

Yuav nrhiav dab tsi:

  • Nto tawg los yog cov plaub hau

  • Laps(overlapping hlau ntws)

  • Scale pits los yog xeb

  • Qhov chaw tsis sib xws lossis cov cim tuag

  • Flash los yog burrs(tshwj xeeb tshaj yog nyob rau hauv kaw tuag forging)

Forgings nrog huv si, du nto thiab cov cim kom raug (cov xov tooj cua sov, batch tooj) muaj feem ntau yuav ua tau zoo.

sakysteel uaxyuas kom txhua qhov forged raug ntxuav thiab tshuaj xyuas qhov muag ua ntej kev sim ntxiv lossis xa khoom.

2. Dimensional thiab Shape Accuracy

Forged Cheebtsam yuav tsum ua raws li qhov ntev thiab kam rau ua. Siv cov cuab yeej ntsuas ntsuas xws li:

  • Vernier calipers

  • Micrometers

  • Coordinate ntsuas tshuab (CMM)

  • Cov duab profile

Tshawb xyuas:

  • Kho qhov ntevraws li kev kos duab

  • Flatness los yog roundness

  • Symmetry thiab uniformity

  • Consistency nyob rau hauv batch

Dimensional sib txawv yuav qhia tau tias tsis zoo tuag zoo los yog tsis tsim nyog forging kub tswj.

3. Mechanical Property Verification

Txhawm rau kom ntseeg tau tias forging tuaj yeem tiv taus qhov hnyav, cov khoom siv kho tshuab yuav tsum tau sim:

Cov kev kuaj pom muaj xws li:

  • Kev ntsuas tensile: Yield zog, tensile zog, elongation

  • Kev sim hardness: Brinell (HB), Rockwell (HRC), lossis Vickers (HV)

  • Kev sim cuam tshuam: Charpy V-notch, tshwj xeeb tshaj yog nyob rau hauv qis-zero kub

Sib piv cov txiaj ntsig nrog cov qauv tshwj xeeb xws li:

4. Ultrasonic Testing (UT) rau Internal Defects

Ultrasonic soj ntsuam yog ibkev kuaj tsis muaj kev puas tsuajsiv los txheeb xyuas qhov tsis zoo ntawm sab hauv xws li:

  • Shrinkage kab noj hniav

  • suav nrog

  • Kev tawg

  • Laminations

Cov qauv xws liASTM A388 Cov khoom lag luam or SIB 1921txhais cov qib kev lees paub UT. High-quality forgings yuav tsum muaj:

  • Tsis muaj kev cuam tshuam loj

  • Tsis muaj qhov tsis xws luag dhau qhov kev tso cai

  • Ntxuav UT cov ntaub ntawv nrog cov ntaub ntawv pov thawj

Tag nrho cov tseem ceeb forgings los ntawmsakysteel uaundergo 100% UT raws li cov neeg siv khoom thiab kev lag luam xav tau.

5. Macrostructure thiab Microstructure Analysis

Kev ntsuam xyuas cov qauv hauv cov nplej yuav pab ntsuas qhov ua tau zoo ntawm cov txheej txheem forging.

Kev ntsuam xyuas Macrostructure (piv txwv li, ASTM E381) kos rau:

  • Flow kab

  • Kev cais

  • Sab hauv tawg

  • Banding

Microstructure tests (xws li ASTM E112) kuaj:

  • Grain loj thiab orientation

  • Phase (martensite, ferrite, austenite)

  • Cov qib kev suav nrog (ASTM E45)

Forgings nrog nplua, cov qauv zoo li qub thiab cov kab sib txuas ua ke feem ntau muab kev qaug zog zoo dua thiab ua haujlwm ntev.
