Cov yam ntxwv tseem ceeb thiab ua rau muaj qhov tsis zoo ntawm cov forgings yog dab tsi?

1. Cov cim qhia ntawm qhov chaw
Cov yam ntxwv tseem ceeb: Kev ua tsis zoo ntawm cov pwmcov khoom siv forgingyuav ua rau muaj qhov chaw ntxhib thiab cov cim nplai ntses. Cov cim nplai ntses ntxhib no yooj yim tsim thaum forging austenitic thiab martensitic stainless hlau.
Ua rau: Cov qog nqaij hauv zos tshwm sim los ntawm kev tsis sib npaug ntawm cov roj nplua nyeem lossis kev xaiv cov roj nplua nyeem tsis raug thiab cov roj nplua nyeem tsis zoo.
2. Yuam kev tsis zoo
Cov yam ntxwv tseem ceeb: Sab saud ntawm lub pwm forging yog misaligned piv rau sab qis raws qhov chaw parting.
Ua rau: Tsis muaj qhov xauv tsis sib npaug ntawm lub pwm forging, lossis lub pwm forging tsis tau teeb tsa kom raug, lossis qhov sib txawv ntawm lub taub hau rauj thiab txoj kev qhia loj dhau.
3. Tsis txaus pwm forging defects
Cov yam ntxwv tseem ceeb: Qhov loj ntawm lub pwm forging nce ntxiv rau hauv qhov kev taw qhia perpendicular rau qhov chaw parting. Thaum qhov loj tshaj qhov loj me teev tseg hauv daim duab, qhov pwm forging tsis txaus yuav tshwm sim.
Ua rau: Qhov loj loj, qhov kub qis forging, hnav ntau dhau ntawm lub qhov tuag, thiab lwm yam yuav ua rau lub siab tsis txaus lossis tsis kam ntau dhau ntawm lub choj flash, qhov khoom siv tonnage tsis txaus, thiab qhov ntim billet ntau dhau.
4. Tsis txaus cov khoom sau hauv zos
Cov yam ntxwv tseem ceeb: Nws feem ntau tshwm sim hauv cov tav, cov ces kaum tuag convex, thiab lwm yam ntawm cov tuag forgings, thiab sab saum toj ntawm qhov sau lossis cov ces kaum ntawm cov forgings tsis tau sau txaus, ua rau cov qauv ntawm cov forgings tsis meej.
Vim li cas: Tus qauv tsim ntawm lub qhov tuag ua ntej thiab lub qhov tuag dawb paug tsis tsim nyog, qhov khoom siv tonnage me me, lub qhov dawb paug tsis sov txaus, thiab cov hlau fluidity tsis zoo, uas yuav ua rau muaj qhov tsis zoo no.
5. Cov khoom seem ntawm cov qauv casting
Cov yam ntxwv tseem ceeb: Yog tias muaj cov qauv casting seem, qhov elongation thiab qaug zog ntawm cov forgings feem ntau tsis tsim nyog. Vim tias ntawm qhov kev sim qis-magnification, cov streamlines ntawm qhov thaiv ntawm cov seem casting tsis pom tseeb, thiab txawm tias cov khoom dendritic tuaj yeem pom, uas feem ntau tshwm sim hauv cov forgings siv cov hlau ingots ua blanks.
Vim li cas: Vim yog qhov sib piv ntawm kev sib tsoo tsis txaus lossis txoj kev sib tsoo tsis raug. Qhov tsis zoo no ua rau cov kev ua haujlwm ntawm cov kev sib tsoo txo ​​qis, tshwj xeeb tshaj yog qhov cuam tshuam thiab cov yam ntxwv qaug zog.
6. Cov noob tsis sib xws
Cov yam ntxwv tseem ceeb: Cov nplej hauv qee qhov ntawmcov khoom siv forgingcov hlau sib xyaw kub thiab cov hlau tiv taus cua sov feem ntau yog cov uas tsis sib xws, thaum cov noob nyob rau lwm qhov me dua, ua rau cov noob tsis sib xws. Cov hlau sib xyaw kub thiab cov hlau tiv taus cua sov yog cov uas rhiab heev rau cov noob tsis sib xws.
Ua rau: Qhov kub qis kawg ntawm kev sib tsoo ua rau cov hlau billet kub siab ua rau tawv tawv. Thaum lub sijhawm quenching thiab cua sov, qee cov nplej loj hlob hnyav lossis qhov kub pib forging siab dhau, thiab qhov deformation tsis txaus, ua rau qib deformation ntawm thaj chaw poob rau hauv qhov deformation tseem ceeb. Qhov tsis sib xws ntawm cov nplej tuaj yeem ua rau kev ua haujlwm qaug zog thiab kev ua haujlwm ntev dua.
7. Cov teeb meem ntawm kev quav
Cov yam ntxwv tseem ceeb: Cov kab nkhaus nkhaus ntawm cov quav ntawm cov qauv qis-magnification, thiab cov quav zoo ib yam li cov kab nrib pleb. Yog tias nws yog ib qho tawg, cov kab nkhaus yuav raug txiav ob zaug. Ntawm cov qauv siab-magnification, tsis zoo li hauv qab ntawm qhov tawg, ob sab yog oxidized hnyav thiab cov quav hauv qab yog blunt.
Ua rau: Nws feem ntau yog vim muaj kev pub tsawg dhau, kev txo qis ntau dhau lossis lub vojvoog anvil fillet me dhau thaum lub sijhawm kos duab ntawm cov pas nrig forgings thiab crankshaft forgings. Cov qhov tsis zoo uas quav tau ua rau cov hlau oxidized sib xyaw ua ke thaum lub sijhawm forging.
8. Kev faib tawm tsis zoo ntawm kev sib tsoo
Cov yam ntxwv tseem ceeb: Ua kom cov cua ntsawj ntshab xws li ua kom cov dej ntws rov qab, cov dej ntws tam sim no, kev sib txuas, thiab kev sib xyaw ua ke tshwm sim thaum lub forging tsis muaj zog.
Ua rau: Tsim cov pwm tsis raug, xaiv txoj kev forging tsis raug, cov duab tsis tsim nyog thiab qhov loj ntawm billet.
9. Cov qauv Banded
Cov yam ntxwv tseem ceeb: Ib qho qauv uas lwm cov qauv lossis ferrite theem hauv kev forgings tau faib ua pawg. Nws feem ntau muaj nyob rau hauv austenitic-ferritic stainless hlau, semi-martensitic hlau thiab eutectoid hlau.
Ua rau: Qhov no yog tshwm sim los ntawm kev sib tsoo deformation thaum ob pawg ntawm cov khoom sib koom ua ke. Nws txo qhov transverse plasticity index ntawm cov khoom siv thiab nws yooj yim tawg raws thaj tsam ferrite lossis ciam teb ntawm ob theem.
