Aluminium alloy tuag castings xa mus rau cov khoom siv txhuas lossis txhuas alloy thiab cov khoom siv tau los ntawm casting. Feem ntau, txhuas lossis txhuas alloy uas yog rhuab mus rau lub xeev ua kua yog nchuav rau hauv pwm kab noj hniav los ntawm cov xuab zeb pwm los yog hlau pwm. Aluminium qhov chaw lossis aluminium alloy qhov chaw ntawm ntau cov duab thiab ntau thiab tsawg tau txais, uas feem ntau hu ua aluminium alloy tuag castings. Aluminium castings nrog niaj hnub complex duab yog raws li nyob rau hauv electromagnetic twj tso kua mis low-pressure casting technology raws li cov tub ntxhais, aluminium smelting thiab molding compound purification technology thiab manufacturing raws li cov tub ntxhais, thiab yog niaj hnub technologies rau zus tau tej cov txhuas castings. Lub tshuab hluav taws xob electromagnetic low-pressure casting molten hlau xa system muaj qhov ruaj khov thiab yooj yim khiav tswj. Thaum lub sij hawm tus txheej txheem, cov kua alumina yog ib qho yooj yim rau backflush thiab yog ib qho yooj yim rau siv. Qhov zoo dua yog tias siv cov txheej txheem automation tsis tsuas yog txhim kho qhov zoo ntawm aluminium castings, tab sis kuj txhim kho qhov chaw ua haujlwm. Txo kev siv zog ua haujlwm thiab paub automation thiab niaj hnub casting ntau lawm.
Cov yam tseem ceeb thiab tsim mechanism ntawm oxidized slag nyob rau hauv tsis xws luag ntawm aluminium alloy tuag-casting qhov chaw. Los ntawm kev txheeb xyuas ntawm cov khoom pov tseg aluminium alloy tuag-casting qhov chaw, nws pom tau hais tias muaj peb yam tseem ceeb ntawm lub rooj vag slag: shrinkage kab noj hniav, roj stains thiab chilled nyuaj txheej. Ntawm lawv, cov roj-muaj slag tso nyiaj rau feem ntau, suav txog ntau dua 60% ntawm tag nrho cov ntsiab lus slag; Cov txheej txheem nyuaj suav txog kwv yees li 35% ntawm tag nrho cov ntsiab lus slag, thiab qhov shrinkage account rau 5% ntawm tag nrho cov ntsiab lus slag. Aluminium alloy tuag-casting tsis xws luag - oxidation slag inclusions yog tshwm sim los ntawm: cov khoom siv hluav taws xob tsis huv, siv cov khoom xa rov qab ntau dhau, tsim tsis zoo ntawm cov txheej txheem pouring, tsis tiav tu slag nyob rau hauv lub molten alloy, tsis tsim nyog pouring hauj lwm, tsis txaus lub sij hawm tom qab refining, thiab suav nrog hauv deterioration Scum. Los ntawm kev tsom xam ntawm aluminium alloy tuag-casting pov tseg cov khoom, muaj peb lub ntsiab ntawm cov rooj vag slag inclusions: shrinkage kab noj hniav, roj stains thiab chilled nyuaj txheej. Ntawm lawv, oily slag account rau feem ntau, accounting rau ntau tshaj 60% ntawm tag nrho cov slag; Cov txheej txheem nyuaj suav txog li 35% ntawm tag nrho cov slag; shrinkage qhov account rau 5% ntawm tag nrho cov slag.
Lub ntsiab zoo ntawm aluminium alloy tuag castings thiab lawv ua hauj lwm kub Lub ntsiab zoo ntawm txhuas tuag casting:
- Aluminium alloy tuag-casting qhov chaw muaj cov yam ntxwv zoo nkauj, lub teeb yuag, thiab kev thauj mus los yooj yim thaum ua haujlwm. Nws kuj yog ib qho txiaj ntsig loj thaum siv hauv tsheb.
- Qhov ntom ntawm aluminium alloy yog qhov qis dua li cov hlau cam khwb cia thiab cam khwb cia hlau, tab sis nws lub zog thiab kev tiv thaiv corrosion yog ntau dua. Yog li ntawd, nyob rau hauv tib lub load hnyav, txhuas tuag-casting tuaj yeem txo qhov hnyav ntawm cov qauv.
- Rau saum npoo ntawm aluminium alloy, nws nto gloss yog zoo heev thiab nws cov kev ua tau zoo casting kuj zoo. Cov khoom siv kho tshuab thiab lub zog tensile ntawm aluminium alloy tuag-casting qhov chaw muaj kev ua haujlwm zoo thaum cov khoom tawg. Rau qee qhov, nws elongation yog ib qho kev ntsuas ntawm brittleness thiab plasticity ntawm cov khoom. Hardness yog qhov tsis kam ntawm cov khoom nto rau cov yas deformation los ntawm extrusion los yog kev sib txhuam los ntawm cov khoom tawv.
- Txheej txheem Aluminium tuag castings yog cov khoom tau los ntawm kev sau, solidifying, thiab txias aluminium alloys nrog kua hlau nyob rau hauv high-pressure casting tej yam kev mob. Vim qhov tsawg viscosity ntawm aluminium alloy yaj, zoo fluidity, siab alloying ntsiab ntsiab lus, yooj yim pwm qauv, thiab low-pressure casting siv low-pressure pouring systems, zus tau tej cov aluminium alloy tuag-casting qhov chaw muaj ntau yam ntxwv.

(2) Muab ntau yam khoom siv raw uas xav tau rau hauv cov thawv sib thooj rau kev npaj. (3) Qhov ntau ntawm cov ntaub ntawv raw yuav tsum tau sau thiab sau npe. (4) Txheeb xyuas cov khoom sib piv raws li qhov xav tau ntau lawm thiab suav qhov hnyav ntawm txhua pawg ntawm cov khoom.
- Blanking: Tshem tawm cov khoom siv raw ntawm cov pwm manually lossis mechanically thiab muab tso rau ntawm qhov chaw ua haujlwm rau kev txiav thiab blanking.
- Rough tig: Txo cov phab ntsa tuab ntawm cov khoom kom ntau li ntau tau thaum ua kom cov khoom tiav ntawm cov khoom, kom ntseeg tau tias cov khoom tuaj yeem ua haujlwm ib txwm ntawm lub tshuab cuab yeej yam tsis ua haujlwm.
- Finishing: Tiav thiab polishing yog ib qho ntawm cov txheej txheem tseem ceeb los txhim kho cov khoom zoo:
- Ua ntej, cov kua txiav tsim nyog yuav tsum raug xaiv los txo qhov roughness ntawm lub workpiece thiab txhim kho nws cov hnav tsis kam; Thib ob, kev saib xyuas yuav tsum tau them rau txoj kev clamping ntawm lub workpiece thiab siv cov cuab yeej los xyuas kom meej qhov ua tau zoo ntawm lub workpiece nto; qhov kawg uas yuav tsum tau them sai sai rau yog kev xa rov qab Cov kab ke feem ntau yog los ntawm sab hauv mus rau sab nraud kom txog rau thaum qhov yuav tsum tau muaj qhov loj thiab qhov tseeb.
- Kev kho cua sov: Txhawm rau tiv thaiv qhov chaw los ntawm deforming lossis tawg, kev kho annealing yuav tsum tau ua kom cov hardness ntawm cov khoom thiab txo lawv cov brittleness, yog li ua rau kev pab cuam lub neej ntawm cov khoom.
- Kev sib dhos: Ua tib zoo saib cov hauv qab no thaum sib dhos:
- ib. Ua ntej sib dhos, cov khoom yuav tsum tau kuaj xyuas seb puas muaj kev puas tsuaj. b. Thaum lub sij hawm installation, lub bolts yuav tsum tau tsau ua ntej thiab ces cov txiv ntseej. c. Thaum zawm cov screws, lub zog yuav tsum txawm thiab tsis dhau xoob. d. Lub positioning pin qhov yog perpendicular mus rau axis center kab thiab kev sib koom ua ke. Parallel e. Qhov kev ncua deb ntawm qhov chaw ntawm qhov chaw tus pin qhov mus rau qhov chaw axis yog 3 ~ 4 hli. f. Qhov kev ncua deb ntawm qhov chaw ntawm tus pin positioning mus rau lub ntsej muag kawg yog 2 ~ 3 hli. g. Cov xov txuas yuav tsum tau tsav los ntawm ib lub cylindrical knurled ntsia hlau khub. Iav kev twb kev txuas Lub trapezoidal ntsia hlau khub yuav tsum tau siv rau kis i. Thaum lub taub sab nraud ntawm lub pulley yog ntau dua 20mm, ob lub taub hau screws yuav tsum tau siv rau zawm.
