Kev kho cua sov ntawm aluminium castings tiag tiag yog ib hom kev tshaj tawm - txheej txheem kev kho casting, ua tom qab casting thiab tu ntawm aluminium castings. Tsis tas li ntawd, nws tseem suav nrog kev tshaj tawm - cov kauj ruam kho xws li kev tsim kho, kev siv tshuab tsis zoo, thiab kev tiv thaiv xeb, thiab lawv daim ntawv thov tiag yog nyob ntawm cov kev xav tau tshwj xeeb.
Tom qab- kev kho casting yog txheej txheem kawg hauv kev tsim cov txhuas castings thiab muaj kev cuam tshuam loj rau qhov zoo ntawm cov castings. Txawm li cas los xij, kev tshaj tawm sib txawv - kev kho mob muaj qhov sib txawv. Piv txwv li, kev kho cua sov yog siv los txhim kho lossis hloov cov qauv qub ntawm aluminium casting. Lub hom phiaj yog txhawm rau tshem tawm cov kev ntxhov siab sab hauv hauv qhov casting, txhim kho kev ua tau zoo ntawm casting, thiab tiv thaiv casting deformation thiab kev puas tsuaj.
Aluminium casting cua sov kev kho mob feem ntau suav nrog quenching, annealing, normalizing, raws li - cam khwb cia tempering, kev laus laus, kev ntxhov siab, softening, thiab kho graphitization, lub hom phiaj ntawm kev ua hauj lwm sib txawv. Piv txwv li, yog hais tias lub casting yuav tsum muaj siab hnav tsis kam thiab txaus toughness, nws cov qauv sab hauv yuav tsum yog austenitic. Yog li ntawd, lub casting yuav tsum tau quenched. Lub casting yog rhuab mus rau lub austenitic cheeb tsam kom tag nrho austenitize nws, thiab ces sai quenched nyob rau hauv dej, tiv thaiv lub austenite los ntawm transforming thiab khaws cia.
Tom qab-kev kho ntawm aluminium castings yog muab faib ua peb yam: kho, kho, thiab nto tiav. Vim tias qee qhov castings yuav deform mus rau qhov sib txawv thaum lub sij hawm khov, txias, thiab kev kho cua sov, ua rau qee qhov ntev tsis kam rau siab, yuav tsum tau kho txoj kev kho. Kev kho tsuas yog siv lub zog siv tshuab ntawm chav tsev kub lossis sov. Thaum lub deformation loj dhau lawm, siab - kho qhov kub thiab txias kuj tuaj yeem ua rau hauv lub qhov cub cua sov uas siv lub casting qhov hnyav los yog ntxiv siab.
Sab nraud tsis xws luag ntawm aluminium castings yog tsuas yog kho siv txoj kev vuam; ntxhib thiab tsis sib xws ntawm cov castings feem ntau polished thiab tiav siv tshem tawm kev sib tsoo log thiab siab - ceev sib tsoo log. Rough machining yog ib qho kev tshaj tawm - cov txheej txheem kev kho mob siv rau qhov tshwj xeeb ntawm aluminium casting. Tom qab kev ua haujlwm ntxhib, qhov tsis xws luag tuaj yeem tshawb pom thiab kho raws sijhawm, txo qhov hnyav, thiab tso cai rau kev faib tawm kom zoo thiab rov ua dua ntawm cov khib nyiab thiab chips. Kev tiv thaiv xeb yog siv los tiv thaiv aluminium castings los ntawm xeb thaum lub sij hawm thauj los yog cia, siv primer txheej.
