Cov ncauj lus kom ntxaws piav qhia ntawm lub caij nplooj ntoo hlav temperiving sov
Kuv {.} txheej txheem qhia
Lub caij nplooj ntoo hlav ua kom sov yog tsim muaj kev sib cav sib txawv ntawm cov hlau hluav taws xob { yog ib txoj kev tseem ceeb nyob rau lub caij nplooj ntoo hlav ntau lawm .
II {{. lub hom phiaj thiab tseem ceeb ntawm tempering
After quenching, the spring's microstructure becomes martensitic, which has high hardness but also high brittleness, making it prone to cracking or deformation. Tempering serves the following purposes:
Txo cov kev ntxhov siab sab hauv thiab tiv thaiv kev tawg;
Stabilizes micriviture microstructure thiab txhim kho cov khoom siv tawv;
Txhim kho elasticity thiab qaug zog tsis kam;
Hloov kho hardness rau ib qho kev haum rau cov ntaub ntawv thov siv tswv yim .
III {. txheej txheem txaus
Cov txheej txheem ntws ntawm lub caij nplooj ntoo hlav tempering tsuas yog suav nrog cov kauj ruam hauv qab no:
Them: Tso lub spenched springs tusyees nyob rau hauv lub cub tawg kom tsis txhob muaj stationing thiab deformation .
Tso kev sov: Teeb ntsuas kub tsim nyog raws li lub caij nplooj ntoo hlau qib (xws li 60si2mn, 55crsi, thiab lwm yam}), feem ntau ntawm 350℃.
Siav: Tswj qhov ntsuas kub rau qee lub sijhawm (feem ntau yog 30 txog 120 feeb) kom ntseeg tau tias muaj kev sib tw tshav kub kub.
Cua txias: Tom qab soaking, txias lub springs maj mam (ntuj cua txias) lossis los ntawm kev yuam cua txias {}
Iv {. hom khoom siv
Caij nplooj ntoos hlav tempering rauv taws tuaj yeem faib raws li lawv cov qauv tsim raws li hauv qab no:
Box-Hom Tempering Rauv: Haum rau me me mus rau nruab nrab batches thiab ntau hom springs; muaj kev ua haujlwm tsis yooj yim .
Mesh Siv Tem Tempering Cub: Txhawb kev tsim khoom txuas ntxiv; Qhov zoo tagnrho rau huab hwm coj ntau lawm ntawm cov qauv me me springs .
PIT-hom TEM TEMIST RAUV: Tsim nyog rau ntev springs lossis loj workpieces; muab cov khoom siv thermal zoo .
COV ROLDER HAV TIM KOM ZEM: Tau tshaj cov kab ntau lawm; Txhim kho cov theem ntawm kev siv hluav taws xob .
V . tswj ntawm cov txheej txheem tseem ceeb
Txhawm rau kom muaj qhov zoo ntawm lub caij nplooj ntoo hlav tempering, cov kab hauv qab no yuav tsum tau nruj me ntsis tswj:
Kev sib dhos kub: Khaws cov cua sov ua kom sov rau kev sib cav sib haum xeeb tsis pub dhau ± 5 degree.
Cua kub tus nqi: Zam kev ua kom sov ntau heev uas tuaj yeem ntxias cov kev ntxhov siab thermal .
Soaking sijhawm: Kho raws li cov ntaub ntawv tuab thiab ua haujlwm loj me .
Kev tswj cov cua: Siv huab cua lossis cov huab cua tiv thaiv (xws li nitrogen) thaum lub sijhawm npau taws kom tiv thaiv oxidation .
VI . Kev Soj Ntsuam Zoo thiab Kev Txhim Kho Kev Txhim Kho
Tom qab tempering, lub springs yuav tsum yauv ua tau cov khoom siv hauv qab no:
Kev kuaj Hardness (e {{{0} g .}, Rockwell Hardness);
Elastic rov qab tus nqi thiab cov kev ntsuas deformation deformation;
Microstructure tsom kwm;
Qaug zog lub neej ntsuas .
Txhawm rau txhim kho cov txheej txheem tempering, cov kev ntsuas nyob hauv qab no tuaj yeem txiav txim siab:
Siv cov tshuab tswj qhov kub thiab txias tswj cov tshuab thiab ntse lub cajmeem;
Siv lub zog-txuag hluav taws xob tsim kho thiab kev ua tau zoo rwb thaiv tsev rwb thaiv tsev;
Sib xyaw nrog quenching rauv thiab ua cov cuab yeej los txhim kho cov qib kev siv tshuab;
Thov mes systems rau cov txheej txheem traceability thiab cov ntaub ntawv tsom .
