Aluminium Gas Meter Housing Stamping Tuag

I. Kev Xaiv Kev Tshawb Fawb Siab - Cov Khoom Siv Zoo Lub hauv paus tseem ceeb rau kev ruaj khov thiab kav ntev ntawm cov pwm nyob hauv cov khoom siv, nrog cov cim tseem ceeb yog hardness, hnav tsis kam, thiab toughness -tag nrho peb yog qhov tseem ceeb. Hauv kev tsim khoom tiag tiag, mainstream siab -zoo pwm steels xws li H13 thiab SKD61 ua tiav hardness ntawm HRC52-58, zoo heev tshav kub tsis kam, thiab muaj peev xwm tiv taus siab - zaus cuam tshuam ntawm 200-500 degree, nrog thermal qaug zog tsis kam tshaj 10,000 cycles ntev-ntev, ua rau lawv tsim nyog. Lub uniformity thiab purity ntawm cov khoom cov tshuaj muaj pes tsawg leeg ncaj qha cuam tshuam pwm stability. Kev siv lub tshuab nqus tsev smelting thiab electroslag remelting technologies tuaj yeem tswj cov ntsiab lus hauv impurity ntawm cov khoom kom qis dua 0.005%, txo qhov tsis xws luag xws li tawg thiab porosity, yog li ncua pwm lifespan ntau dua 30% los ntawm qhov chaw.

II. Kev Tshawb Fawb thiab Kev Tsim Nyog Tsim Kev Txhim Kho Pwm tsim ncaj qha txiav txim siab nws txoj kev ntxhov siab thiab kev sib faib ntawm cov cua sov, uas yog qhov tseem ceeb rau kev zam kom tsis txhob muaj pwm ua ntej. Siv CAD tsim ua ke nrog FEA finite element tsom xam tshuab, cov cheeb tsam kev ntxhov siab, deformation, thiab kub tis thaum lub sij hawm pwm tuaj yeem raug simulated. Qhov no tso cai rau kev zam thaum ntxov ntawm cov qauv ua tsis tau yooj yim xws li cov kaum ntse ntse thiab cov npoo nyias, txo cov pwm kev ntxhov siab ntau dua 40%. Kev ua kom zoo ntawm cov qauv pwm (xws li, ntxiv kev txhawb nqa cov tav thiab qhov chaw zoo ntawm qhov rooj) txhim kho tag nrho cov rigidity thiab lub zog ntawm cov pwm, txo cov kev qaug zog hauv zos, thiab ua rau pwm deformation nyob rau hauv 0.002mm, kom ruaj khov pwm kev ua tau zoo thaum lub sij hawm tsim khoom.

III. Kev siv cov txheej txheem kho cua sov siab tshaj plaws Kev kho cua sov yog txheej txheem tseem ceeb rau kev txhim kho pwm, ncaj qha txiav txim siab sab hauv microstructure ntawm pwm. Los ntawm cov txheej txheem quenching thiab tempering, lub hardness ntawm pwm hlau tuaj yeem nce mus rau tus qauv tsim thaum ua kom ntseeg tau tias lub toughness ua tau raws li qhov yuav tsum tau ua. Lub quenching kub yog tswj ntawm 850-1050 degree, tuav rau 2-4 teev, thiab roj los yog cua txias yog siv los tiv thaiv pwm deformation. Lub tempering kub yog 200-500 degree, thiab tempering yog ua nyob rau hauv 2-3 theem kom tshem tawm kev ntxhov siab nyob rau hauv, tsim ib tug ntom thiab uniform quenched martensitic qauv nyob rau hauv lub pwm. Qhov no nce hnav tsis kam los ntawm 50% thiab qhov cuam tshuam toughness mus txog 15-20 J / cm², tiv thaiv chipping thiab tawg thaum siv pwm.

IV. Kev them nyiaj yug los ntawm High-Efficiency Surface Treatment Technology Surface Treatment tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov pwm thiab txuas nws lub neej kev pab cuam. Nqus nitriding tuaj yeem ua rau lub ntsej muag tawv ntawm cov pwm kom siab dua HRC65, txhim kho hnav tsis kam los ntawm 60%, thiab tsim cov txheej tuab nitrided kom zoo tiv thaiv corrosion thiab oxidation. Chromium plating tuaj yeem txo qhov roughness ntawm cov pwm kom qis dua Ra0.1, txo cov kev sib txhuam ntawm cov khoom ua haujlwm thiab cov pwm, thiab txo qhov kev pheej hmoo ntawm pwm sticking. Laser quenching tau precisely ntxiv dag zog rau qhov yooj yim hnav ntawm cov pwm, nrog ib tug ntxiv dag zog txheej txheej ntawm qhov tob ntawm 0.5-2 hli, uas yuav ua rau kom lub neej kev pab cuam ntawm ib feem los ntawm ntau tshaj 2 lub sij hawm thiab ncua tag nrho cov kev pab cuam lub neej ntawm cov pwm.
