Kev txheeb xyuas tag nrho ntawm txias thiab kub ua haujlwm tuag hlau nrog kev kho cua sov thiab cov roj quenching
Tso lus
I. Cov tub ntxhais sib txawv ntawm cov khaub thuas thiab kub ua haujlwm tua cov hlau
Cov khoom siv muaj pes tsawg leeg thiab cov khoom
Txias ua haujlwm tuag hlau: feem ntau muaj cov roj carbon (1.3%- 2.3%), muaj alloy), molybdenum (mo), thiab tungsten (w). Nws hais txog hardness siab (58-64 hrc) thiab hnav tsis kam, thiab yog haum rau chav-kub ua (xws li cov stamping thiab txias hau). Cov qauv steel yog suav nrog CR12, CRR12MOV, thiab DC53.
Kub ua hauj lwm hlau: muaj cov ntsiab lus roj carbon ntau (0.3%- 0.6%). Cov ntsiab lus xws li chromium (cr), w), thiab silicon (SI muaj peev xwm los txhawb nqa hardness (thermal conductivity. Nws yog siv nyob rau hauv qhov chaw kub-ib puag ncig (500 15 degree), xws li tuag casting thiab kub forging. Tus sawv cev steel qib muaj xws H13, PCR2W8V, thiab 5CRNIMO.
Tuag Hlau
Txias Ua Haujlwm Tuag Hlau
Cov Ntawv Thov
Txias chaw ua haujlwm Des: Blanking tuag, txias extusion dies, hlau kos duab tuag, thiab lwm yam haujlwm ntawm qhov kub tshaj hauv qab 200 degree.
Cov Khoom Siv Kub Dies: Kub Forging Tuag, Tuag {0} Casting Dies, thiab lwm yam.
Ii. Cov Txheej Txheem Cov yam ntxwv ntawm lub tshuab nqus tsev sov thiab cov roj quenching
1. Lub tshuab nqus roj quenching rau khaub ncaws txias steel
Cov kauj ruam kauj ruam:
Preheat kev kho mob: suav nrog annealing (kom tshem tawm sab hauv kev ntxhov siab), ib txwm muaj (los ua kom zoo dua tshiab), thiab temerving micruction micructure).
Kawg sov kev kho mob:
Nqus quenching: cua sov hauv lub tshuab nqus tsev kom tsis txhob muaj oxidation thiab decarburization roj) kom txo qis kev pheej hmoo ntawm deformation thiab tawg.
Tempering: Tsawg {{{- kub tempering (180 {}} 2500-500 degree) kom sib npaug nruj thiab hnav tsis kam.
Qhov Zoo:
Micro - deformation: Cov cua sov tsis sib xws ntawm cov roj quenching, txo qis kev ua yeeb yam mould deformation.
Cov Khoom Zoo Zoo: Zam cov kua oxide, txo qhov xav tau rau kev ua tiav tom ntej.
Txhim kho lub neej: piv txwv li, tom qab nqus roj quenching, cov coj tsis kam thiab nkees muaj zog ntawm crachmov hlau nce los ntawm 30% -50%.
2. Lub tshuab nqus roj quenching rau kub ua haujlwm tuag hlau
Cov kauj ruam kauj ruam:
Preheat kev kho mob: siab {- kub tempering (600-650 degree) kom ruaj khov kho microstructure.
Kawg sov kev kho mob:
Nqus quenching: cua sov rau 1000 - 1150 degree, thiab siab -650 degree) los txhim kho lub hardness thiab thermal rog tsis kam.
Qhov Zoo:
Thermal nkees ua kom tsis kam: Kev ntsuas lub zog ua kom tsis xws luag, thaum high {{qhov kub sim ua kom ruaj khov, txuas ntxiv mouldide faib khoom, txuas ntxiv Mouldide faib khoom nyob rau hauv thermal cycling.
Piv txwv li Liab hardness kev txhim kho: piv txwv li tus qauv H13 tuaj yeem tswj hwm lub hardness ntawm ntau dua los yog sib npaug rau 45℃tom qab nqus roj quenching. HRC 8.
III. Txheej txheem parameter sib piv thiab ceev faj
Txias ua haujlwm steel: Tsis txhob khaws kev ua kom dhau los ntawm Austenite tshwm sim los ntawm high - kub quenching. Cryogenic kev kho (hauv qab -70 degree) yuav tsum tau hloov Austenite thiab nce kev nyuaj.
Cov kub ua haujlwm steel: lub sijhawm tempering yuav tsum nruj me ntsis tswj (2-4 teev) kom tag nrho cov kev ntxhov siab thiab tiv thaiv kev tawg.
IV. Cov Ntaub Ntawv Thov Raug Zoo
Txias ua haujlwm Tuag Piv Txwv: Cr12mov Silicon daim ntawv Silicon Steel Stamping Dies tau ntau dua peb zaug tom qab lub nqus roj quenching ncav cuag ± 0.01mm.
Kub ua haujlwm tuag Piv Txwv: PCCR2V tuag {} Casting Diesting} kub tuag rau aluminium} tuag {}}}.
V. Cov Ntsiab Lus
Lub tshuab nqus roj quenching thev naus laus zis txhim kho cov kev ua tau zoo ntawm ob qho tib si txias thiab kub}} ecidizing cua sov thiab cua txias:
Mob khaub thuas ua haujlwm tuag hlau: tsom mus rau lub siab tawv thiab hnav tsis kam, lub nqus tsev ua deformation thiab yog tsim rau precision stamping.
Kub ua haujlwm tuag hlau: tsom rau kub hardness thiab thermal rog ua hauj lwm, thaum siab} kub ntxiab ua ke nrog kev txhim kho lub siab - kub khov.
Cov txheej txheem sib txawv ntawm ob hom lus nyob hauv quenching kub, tempering specifications, thiab alloy tsim. Cov kev daws teeb meem zoo tshaj plaws yuav tsum tau xaiv raws li cov haujlwm ua haujlwm tshwj xeeb.
