Lub induction quenching yog txheej txheem quenching uas siv cov nyhuv thermal tsim los ntawm qhov induction tam sim no dhau los ntawm kev sib tsoo kom sov rau saum npoo thiab hauv zos ntawm qhov forging mus rau qhov kub thiab txias, ua raws li qhov txias txias. Thaum lub sij hawm quenching, lub forging yog muab tso rau hauv ib tug tooj liab txoj hauj lwm sensor thiab kev cob cog rua rau ib tug alternating tam sim no ntawm ib tug taag zaus los tsim electromagnetic induction, uas ua rau ib tug induced tam sim no nyob rau saum npoo ntawm forging uas yog opposite rau tam sim no nyob rau hauv lub induction kauj. Lub voj kaw tsim los ntawm qhov induced tam sim no nyob rau saum npoo ntawm forging yog hu ua eddy tam sim no. Nyob rau hauv qhov kev txiav txim ntawm qhov eddy tam sim no thiab qhov tsis kam ntawm forging nws tus kheej, lub zog hluav taws xob tau hloov mus rau hauv thermal zog ntawm qhov chaw ntawm forging, ua rau saum npoo kom sov sai li sai tau mus rau quenching overflow, tom qab uas lub forging yog tam sim ntawd thiab sai. txias kom ua tiav lub hom phiaj ntawm nto quenching.
Yog vim li cas eddy tam sim no tuaj yeem ua tiav cov cua sov saum npoo yog txiav txim siab los ntawm cov yam ntxwv ntawm kev sib hloov tam sim no hauv tus neeg xyuas pib. Cov yam ntxwv no muaj xws li:
- Cov nyhuv ntawm daim tawv nqaij:
Thaum cov hluav taws xob ncaj qha (DC) dhau los ntawm tus neeg xyuas pib, qhov ceev tam sim no yog sib xws nyob rau ntawm ntu ntu ntawm tus neeg xyuas pib. Txawm li cas los xij, thaum hloov pauv tam sim no (AC) dhau mus, qhov kev faib tawm tam sim no thoob plaws tus neeg xyuas pib hla ntu tsis sib xws. Tam sim no qhov ceev yog siab dua nyob rau saum npoo ntawm tus neeg xyuas pib thiab qis dua ntawm qhov chaw, nrog rau qhov tam sim no qhov ceev yuav txo qis exponentially los ntawm qhov chaw mus rau qhov chaw. Qhov tshwm sim no yog hu ua daim tawv nqaij nyhuv ntawm AC. Qhov siab dua qhov zaus ntawm AC, qhov ntau tshaj tawm cov nyhuv ntawm daim tawv nqaij. Induction cua sov quenching siv cov yam ntxwv no kom ua tiav cov txiaj ntsig xav tau.
- Cov nyhuv sib thooj:
Thaum ob lub conductors uas nyob ib sab dhau los ntawm qhov tam sim no, yog tias qhov kev taw qhia tam sim no zoo ib yam, qhov cuam tshuam rov qab muaj peev xwm nyob rau sab uas nyob ib sab ntawm ob tus neeg xyuas pib yog qhov loj tshaj plaws vim yog kev sib cuam tshuam ntawm cov chaw sib nqus sib nqus tsim los ntawm lawv, thiab tam sim no tau tsav mus rau. sab nraud ntawm tus neeg xyuas pib. Ntawm qhov tsis sib xws, thaum qhov kev taw qhia tam sim no yog qhov sib txawv, qhov tam sim no tau tsav mus rau sab uas nyob ib sab ntawm ob tus neeg xyuas pib, uas yog, lub hauv paus ntws, qhov tshwm sim no hu ua qhov sib thooj.
Thaum lub sij hawm induction cua sov, induced tam sim no ntawm lub forging yog ib txwm nyob rau hauv lub opposite kev taw qhia ntawm tam sim no nyob rau hauv lub nplhaib induction, yog li tam sim no nyob rau hauv lub nplhaib induction yog concentrated nyob rau hauv lub ntws, thiab tam sim no nyob rau hauv lub rhuab forging nyob rau hauv lub induction nplhaib. yog concentrated rau saum npoo, uas yog qhov tshwm sim ntawm qhov sib thooj nyhuv thiab cov nyhuv ntawm daim tawv nqaij superimposed.
Nyob rau hauv qhov kev txiav txim ntawm qhov sib thooj nyhuv, qhov kev faib tawm ntawm qhov induced tam sim no nyob rau saum npoo ntawm forging yog ib yam nkaus xwb thaum qhov sib txawv ntawm induction kauj thiab forging yog sib npaug. Yog li ntawd, lub forging yuav tsum tau tig tsis tu ncua thaum lub sij hawm induction cua sov txheej txheem kom tshem tawm los yog txo cov cua sov unevenness tshwm sim los ntawm qhov tsis sib xws, thiaj li yuav tau ib tug uniform cua sov txheej.
Tsis tas li ntawd, vim muaj qhov sib thooj, cov duab ntawm qhov chaw rhuab ntawm lub forging yog ib txwm zoo ib yam li cov duab ntawm induction coil. Yog li ntawd, thaum ua lub induction kauj, nws yog ib qho tsim nyog yuav tsum ua kom nws cov duab zoo ib yam li cov duab ntawm cov cua sov ntawm lub forging, thiaj li ua tau zoo dua cua sov.
- Circulation Effect:
Thaum alternating tam sim no dhau los ntawm lub nplhaib-zoo li tus neeg xyuas pib los yog helical conductor, vim qhov kev txiav txim ntawm alternating magnetic teb, qhov tam sim no ceev nyob rau sab nrauv ntawm tus neeg xyuas pib txo qis vim qhov nce ntawm tus kheej inductive rov qab electromotive quab yuam, thaum lub puab nto ntawm tus neeg xyuas pib. lub nplhaib tau txais qhov siab tshaj plaws tam sim no. Qhov tshwm sim no yog hu ua cov nyhuv ncig.
Cov nyhuv ncig tuaj yeem txhim kho cov cua sov kom zoo thiab ceev thaum cua sov rau sab nrauv ntawm ib daim forged. Txawm li cas los xij, nws yog qhov tsis zoo rau cua sov lub qhov hauv sab hauv, vim tias cov nyhuv ncig ua rau cov tam sim no hauv inductor txav mus deb ntawm qhov chaw ntawm cov khoom forged, ua rau txo qis cua sov kom zoo thiab qeeb cua sov ceev. Yog li ntawd, nws yog ib qho tsim nyog los nruab cov khoom sib nqus nrog cov permeability siab ntawm inductor los txhim kho cov cua sov kom zoo.
Qhov loj dua qhov sib piv ntawm qhov siab axial ntawm lub inductor mus rau txoj kab uas hla ntawm lub nplhaib, qhov ntau pronounced cov nyhuv ncig. Yog li ntawd, qhov cross-section ntawm inductor yog qhov zoo tshaj plaws ua cov duab plaub; ib lub duab plaub zoo dua li lub square, thiab lub voj voog yog qhov phem tshaj plaws thiab yuav tsum zam kom ntau li ntau tau
- Lub sharp Angle nyhuv:
Thaum lub protruding qhov chaw nrog ntse ces kaum, ntug npoo thiab me me curvature vojvoog yog rhuab nyob rau hauv lub sensor, txawm yog hais tias qhov sib txawv ntawm lub sensor thiab forging yog sib npaug zos, lub magnetic teb kab ceev los ntawm lub ntse ces kaum thiab protruding qhov chaw ntawm lub forging yog loj. , qhov induced tam sim no ceev yog loj, cua kub ceev ceev, thiab cov cua sov yog concentrated, uas yuav ua rau cov khoom no overheat thiab txawm hlawv. Qhov tshwm sim no yog hu ua lub ntsej muag ntse.
Txhawm rau kom tsis txhob cuam tshuam lub kaum ntse ntse, thaum tsim lub sensor, qhov sib txawv ntawm lub sensor thiab lub ntsej muag ntse los yog convex ib feem ntawm forging yuav tsum tau nce kom tsim nyog los txo cov concentration ntawm cov hlau nplaum sib nqus nyob rau ntawd, kom cov cua kub ceev thiab qhov kub ntawm forging nyob txhua qhov chaw yog sib xws li qhov ua tau. Lub kaum ntse ntse thiab qhov chaw ntawm qhov forging kuj tuaj yeem hloov mus rau ko taw fab lossis chamfers, kom cov nyhuv tib yam tuaj yeem tau txais.
