Kev faib tawm ntawm kev ua cov txheej txheem rau aluminium alloy log

Lub ntiajteb txawj nqus Casting
Casting yog cov txheej txheem tseem ceeb tshaj plaws hauv kev lag luam hlau. Raws li lub sijhawm ua ntej keeb kwm, tib neeg paub siv txoj hauv kev los ua riam phom thiab lwm yam khoom siv tooj liab. Cov txheej txheem no suav nrog cua sov cov hlau mus rau lub xeev molten thiab muab tso rau hauv pwm kom nws txias thiab khov. Qhov li -hu ua "lub ntiajteb txawj nqus casting" yog txheej txheem uas cov kua txhuas puv tag nrho cov pwm nyob rau hauv lub zog ntawm lub ntiajteb txawj nqus. Txawm hais tias txoj kev tsim khoom no yog pheej yig thiab yooj yim, nws yog qhov nyuaj los xyuas kom meej qhov sib xws ntawm lub log, nws yooj yim ua npuas, thiab muaj zog thiab tawm los. Niaj hnub no, cov cuab yeej no tau maj mam dhau mus.

Tsawg-siab casting
Tsawg-pressure casting yog ib txoj kev casting uas siv roj siab los quab yuam cov hlau ua kua rau hauv pwm thiab ua rau cov casting crystallize thiab solidify nyob rau hauv ib tug tej yam siab. Txoj kev no ua rau cov kua hlau ua kom cov pwm sai sai. Since the gas pressure is not too intense, it can increase the metal density without involving air. Piv nrog lub ntiajteb txawj nqus casting, cov qauv sab hauv ntawm lub log nyob rau hauv qis -siab casting yog ntau compact thiab muaj zog. Tsawg-siab casting muaj ntau dua efficiency, ib tug ntau dua cov khoom tsim nyog tus nqi, zoo mechanical zog ntawm lub casting, ib tug siab siv tus nqi ntawm cov molten aluminium, thiab yog haum rau loj -scale batch ntau lawm. Tam sim no, feem ntau nruab nrab - mus rau - qis- kawg cam khwb cia log log yog tsim los siv cov txheej txheem no.

Rotational casting
Rotational casting yog me ntsis zoo ib yam li cov txheej txheem shaping hauv ceramic manufacturing. Nws yog raws li lub ntiajteb txawj nqus casting los yog tsawg-siab casting, thiab los ntawm kev sib hloov ntawm txhuas nws tus kheej thiab extrusion thiab stretching ntawm lub rotating cutter, lub log rim yog maj elongated thiab thinned. Lub log rim undergoes kub rotational molding, thiab nws cov qauv muaj pom tseeb fiber ntau cov kab, ho txhim khu lub zuag qhia tag nrho lub zog thiab corrosion kuj ntawm lub log. Vim nws cov khoom muaj zog, lub teeb khoom hnyav, thiab cov khoom me me molecular khoob, nws yog ib qho kev qhuas heev hauv kev ua lag luam tam sim no.

Integrated forging
Forging yog ib txoj kev ua haujlwm uas siv cov tshuab forging los siv lub siab rau cov hlau billets, ua rau lawv mus rau cov yas deformation kom tau txais cov khoom forged nrog qee yam khoom siv, cov duab tshwj xeeb, thiab qhov ntev. Tom qab forging, aluminium billet muaj cov qauv hauv tsev ntau dua, thiab cov txheej txheem forging tuaj yeem ua tau zoo dua kev kho cua sov ntawm cov hlau, ua kom nws ua tau zoo dua thermal zog. Txij li cov txheej txheem forging tsuas tuaj yeem ua tiav tag nrho cov hlau hlau thiab tsis tuaj yeem tsim cov duab tshwj xeeb, tom qab forging, aluminium billet tseem yuav tsum tau ua cov txheej txheem txiav thiab polishing, thiab nws cov nqi kuj tseem ntau dua li cov txheej txheem casting.

Ntau- daim forging
Integrated forging yuav tsum txiav tawm qhov loj ntawm qhov ntev, uas ua rau lub sijhawm ua haujlwm siab thiab tus nqi. Txhawm rau kom ua tiav tib yam kev ua haujlwm zoo ib yam li kev sib koom ua ke forged log, thaum txo cov sijhawm ua haujlwm thiab cov nqi, qee lub tsheb log tsheb tau siv ntau - daim forging txheej txheem. Ntau -daim forged log tuaj nyob rau hauv ob hom: lub qub muaj spokes thiab rims, thaum lub tom kawg muaj xws li pem hauv ntej daim, rear daim, thiab spokes. Vim muaj teeb meem ntawm seams nyob rau hauv peb - thooj log, ntxiv sealing kev kho mob yuav tsum tau tom qab sib dhos los xyuas kom meej airtightness. Tam sim no, muaj ob txoj kev sib txuas tseem ceeb rau lub log rims ntawm ntau- daim forged log: ib qho yog ib qho kev sib txuas ntawm bolt / txiv ntseej; lwm qhov yog vuam. Txawm hais tias tus nqi ntawm ntau -daim forged log yog qis dua li ntawm cov log sib xyaw ua ke, nws poob luv luv ntawm qhov hnyav.

Compression casting
Cov txheej txheem forging yog yooj yim rau kev ua cov txheej txheem -zoo li tus. Cov txheej txheem forging ua rau cov khoom kom muaj cov khoom zoo dua qub. Thaum extrusion casting muab qhov zoo ntawm ob qho tib si. Cov txheej txheem no suav nrog kev nchuav cov hlau ua kua rau hauv lub thawv qhib, thiab tom qab ntawd lub siab - lub siab ram presses cov kua hlau rau hauv pwm los sau, tsim, thiab txias thiab crystallize. Txoj kev ua haujlwm no ua tau zoo kom muaj kev sib haum xeeb hauv lub log, nrog cov cuab yeej cuab tam nyob ze rau ntawm lub log monolithic forged. Nyob rau tib lub sijhawm, tsis muaj ntau cov khoom pov tseg uas yuav tsum tau txiav. Tam sim no, ntau lub log hauv Nyij Pooj tau siv txoj kev ua haujlwm no. Vim nws cov qib siab ntawm kev txawj ntse, ntau lub lag luam tau suav tias extrusion casting yog ib qho ntawm cov lus qhia ntau lawm rau tsheb log.
