Daim ntawv thov ntawm ultrasonic tsis nyob rau hauv kev txiav txim siab qhov tsis xws luag ntawm cov ncej loj

Nyob rau hauv lub ntsiab nco txog kev sim thev naus laus zis, ultrasonic qhov kev ntsuas ultrasonic tau siv vim yooj yim nqa cov cuab yeej siv, qhov chaw siab yog qhov tseeb thiab qhov tshwm sim ntawm kev tsis taus sab hauv. Daim ntawv no feem ntau yog qhia cov yam ntxwv ua kom muaj ntau hom kev tawm tsam sab hauv los ntawm cov laj thawj sab hauv

Raws li kev qhia tawm hom kev faib tawm, cov qauv khawb ultrasonic tuaj yeem faib ua txoj kev nkag mus thiab tshuaj nthwv dej thiab cov mem tes reflection txoj kev. Ntawm lawv, Mem Tes Reflectioned mus rau A, Q, qhov loj me, tab sis kuj tseem tuaj yeem siv cov kev xav tau, yog li nws tseem siv dav.

Tus qauv ntawm kev sim cov khoom siv hauv daim ntawv no yogYUSHI YUT -2800 Ultrasonic Plab Phwv Ntes Ntes, Thiab qhov loj ntawm kev tsis xws luag yog txiav txim los ntawm cov qauv sib npaug, thiab rhiab yog φ2 hauv qab.

1.gener ntawm cov pej xeem sab hauv

Kev zam txim sab hauv nyob rau hauv kev zam txim feem ntau tsis suav nrog, yog cov txheej txheem ua kua, thiab muaj xwm txheej phem, tuaj yeem ua rau txhawm rau txhawm rau txhawm rau ntawm kev ua kom pom tseeb. Qhov no yog vim tias muaj kev suav nrog tsis tsuas yog thaiv txuas ntxiv ntawm cov hlau ntawm cov kab nrib pleb, yooj yim los ua cov kev ntxhov siab thiab thaum kawg tsim cov microcacks. Lub xub ntiag ntawm suav muaj cov txiaj ntsig me me ntawm lub zog ntawm workpiece nws tus kheej, tab sis lwm yam khoom, thiab muaj qhov cuam tshuam loj tshaj plaws ntawm kev muaj txiaj ntsig ntawm kev muaj txiaj ntsig.

Muaj peb waveforms rau kev kuaj pom ntawm ntau hom kev suav nrog thaum muaj qee qhov kev cuam tshuam nrog kev tawm hws, raws li nws qhov siab los txiav txim qhov loj me ntawm qhov tsis xws luag. Txoj siv tawv tsis muaj peev xwm tshwm sim hauv txoj kev sib tsoo ntawm qhov kev sim ua kom pom tseeb thaum cov kev soj ntsuam kev zam txim rau qee yam kev lom zem, lub teeb pom kev nyab xeeb tsis ploj.

2.ngener ntawm cov kab nrib pleb sab hauv

Loj ncau sau cia hauv kev ua kom tau kev kho cua sov lossis kev ntxhov siab zaum kawg yuav tsim kev ntxhov siab me me, yog li cov kab nrib pleb, yog li cov kab nrib pleb Lub ncov ntawm hom nrib pleb tsis zoo yog "ntse thiab muaj kev cuam tshuam loj heev. Qhov no yog vim muaj cov kab nrib pleb, kab nrib pleb hauv lub tshuab nqus dej lossis cov plaub hau muaj zog kom dhau los ntawm cov plaub hau me me, yog li txiav lub zog ultrasonic kom ncav cuag hauv qab ntawm workpiece.

3.Gener ntawm "dawb chaw"

Vim tias cov pob dawb txiav cov txuas ntxiv ntawm cov matrix, lawv tuaj yeem yooj yim ua rau cov txheej txheem kho cua sov tom qab, yog li cov pob dawb tsis tau tso cai hauv cov hlau. Raws li dawb nqaij tawg feem ntau jagged, cov ntse cov fab yuav tsis muaj zog, nyob rau hauv qhov kev pom tau muaj zog yuav muaj qee yam cuam tshuam rau hauv qab nthwv dej. Most of the view that the "white spot" is caused by high hydrogen content, hydrogen in the steel is usually divided into diffusible and non-diffusible hydrogen, and can cause the white point of hydrogen is generally diffusible hydrogen, the part of the hydrogen content reaches a certain level after the fracture strength of the steel will be significantly reduced, resulting in hydrogen embrittlement fracture occurs. CR5 steel dehydogenation (TDS) cov kev sim tau ua pov thawj tias nws tuaj yeem ua tau diffused. TDS (TDS) Cov kev sim tau ua pov thawj tias qhov tseem ceeb ntawm hydrogen ntawm chav tsev kub yog, ntau dua li cov ntsuas kub khov kho, cov pob zeb ruaj khov, cov pob zeb me me classlement tej yam yuav tsis cuam tshuam.

Cov dawb dawb yog ntse, ntau thiab kev ywj pheej ntawm txhua lwm yam, thiab muaj cov nyhuv tseem ceeb rau tus naj npawb ntawm cov hauv qab thiab cov vuag.

Cov pob dawb yog qhov tseem ceeb micro nrib pleb uas yuav tsum tau txhim kho me me, yog li lawv cov tshuaj pom kom zoo, thiab cov nplaim nyob hauv qab yog loj heev.

4.Peneration ntawm Nyom-puab WaveForm

Ultrasonic tsis nyob rau hauv cov txheej txheem tshaj tawm, thaum twg ntsib hauv lub acoustic impedance ntawm cov kev ua kom sib txawv, nws yuav ua rau "nyom duab. Qhov no Wervforming rau cov khoom siv 30cr1mo1v, Lis loj, feem ntau los ntawm kev kho mob rov kho dua tshiab tuaj yeem tshem tawm los ntawm kev txo qhov loj ntawm cov nplej.

 5.Paration ntawm kev xau dej caw

Kev xau xau suav nrog kev suav nrog lub qhov muag liab qab ntawm qhov chaw ua haujlwm tom qab kev tsis txaus siab, thiab xws li tsis xws luag tsis pub muaj cov qauv zoo.

Lub sijhawm uas muaj peev xwm sib cais tuaj yeem piav qhia txog kev txav ntawm qhov tsis xws luag ntawm qhov chaw ntawm kev hloov ntawm txoj haujlwm uas tshwm sim thaum lub sijhawm kev ntxhov siab hauv cov txheej txheem smelting. Thaum lub sij hawm forging, cov ntu ntawm thaj chaw thaj chaw muaj rau peb txoj kev sib cav sib ceg, uas ua rau cov neeg sib cav sib ceg me me, thaum nyob sab hauv ntawm kev Forging yog raug rau lub zog me me. Raws li lub hauv paus ntsiab lus tsawg kawg tsis kam, cov koom haum lis hmoov nplej hauv ob-txoj kev quab yuam yuav tsim cov kev nthuav dav loj nrog cov kev taw qhia loj; Tsis tas li ntawd, nyob rau sab nraud ntawm kev forging, vim yog qhov nthuav dav ntawm qhov chaw loj ntawm qhov chaw loj ntawm qhov deformation tshwm sim upward lossis qis dua khoov.

Noj chim ib yam li ib qho piv txwv, thaum lub Upper Upsetting disk yog ntau dua li qhov tsis xws luag mus rau hauv lub siab, thiab yog li ntawd qhov kev xau thaum lub tshuab ua kom qeeb. Txawm li cas los xij, thaum tsis xws luag yog nyob ze rau lub plawv, raws li qhov tsis kam ua rau lub tshuab tsis kam ua rau ntawm kev forging ntawm rotors thiab qaws feem ntau.

Cov kev txheeb xyuas saum toj no luv luv qhia txog kev siv ultrasonic kev sim ua kom pom cov teeb meem tshwj xeeb, tab sis nyob rau hauv cov teeb meem kev ua haujlwm tau pom muaj ntau yam teeb meem Yog tias koj muaj kev ntsuas nyuaj, txais tos xa koj cov workpiece. YUSKI YUAV UA RAU KOJ COV KEV PAB!
