Ntau tus tuaj yeem hais txog qhov tseem ceeb ntawm kab nuv ntses rau tus neeg nuv ntses tiag tiag. Ib qho kab nuv ntses zoo yog tus yuam sij rau kev ua tiav nuv ntses. Nws feem ntau tshwm sim tias cov nyiam jig (lub npe cuav ntawm cov neeg) tau ploj mus rau hauv cov txheej txheem kev nuv ntses. Peb yuav qhia koj seb yuav ua li cas kom muaj ib qho kab nuv ntses zoo sib xws hauv tsev.
Nws yog qhov tsim nyog
- - jigs rau lub qauv casting;
- - cov thawv ntawv me me;

Cov Lus Qhia
Kauj ruam 1
Ua ib lub thawv me me tawm ntawm cardboard, koj tuaj yeem nqa ua tiav. Dilute lub gypsum mus rau lub sib xws ntawm tuab qaub cream. Ncuav cov tshuaj npaj rau hauv ib lub thawv, txhaws nws li ib nrab. Ntub lub jigs siv los ua qauv nrog tshuab roj.
Kauj ruam 2
Tso lawv rau hauv cov tshuaj npaj tau thiab nias maj mam. Hauv cov ces kaum ntawm lub thawv, ntxig rau plaub tshooj, taub hau los. Tam sim no koj yuav tsum tau tos 15 feeb rau kev daws teeb meem kom tawv. Tom qab ntawd lo rau tag nrho saum npoo ntawm hom pwm nrog rau tag nrho nws cov ntsiab lus nrog ib txheej nyias ntawm cov tshuab roj. Tom qab ntawd ncuav tus so ntawm gypsum rau hauv lub thawv. Kev daws yuav tsum tawv. Tom qab ntawd, siv rab riam, tev daim ntawv los ntawm daim duab los qhia thiab ua tib zoo cais nws mus rau hauv ob halves ntawm daim foos. Tom ntej no, nqa tawm cov qauv jigs.
Kauj ruam 3
Ntawm ib nrab hnub, siv rab riam ntse los ua kom ntws tawm sab hauv thiab cov cua tawm mus sab nraud kom tiv thaiv cov khoom ntws los ntawm lawv. Tshem tawm cov ntawv nplaum plaster ntawm cov pwm thiab ua kom cov hooks muaj nyob rau hauv cov chaw tsim nyog. Quav ob leeg ua ke ib nrab. Daim foos tau npaj lawm.
Kauj ruam 4
Sau cov pwm nrog cov xim hlau. Siv cov hlau lead ntawm cov hmoov txhuas thiab cov yajthem ua cov khoom siv casting, piv txwv li POS-18, qhov twg cov ntsiab lus tin yog 18%, lossis POS-30, nrog qhov muaj 30% tin. Muab cov hlau tso rau hauv qhov npaj tau tin thiab muab tso rau ntawm lub qhov cub. Nco ntsoov siv cov hlaws nrog qhov nqaim nqaim kom cov hlau tsis ntws dhau lub pwm. Sib sau daim ntawv thiab ruaj khov nws nrog xaim. Ncuav cov alloy rau hauv cov hlau ntws nrog ib txoj kab nyias nyias thiab cia nws ua kom zoo.
Kauj ruam 5
Hauv ob peb feeb, qhib daim ntawv - cov jigs tau npaj tiav. Siv daim ntawv lossis sab txiav tawm kom tshem tawm cov alloy, thiab siv rab koob siv hlau los ua qhov rau txoj leeg. Sand qhov tiav tiav kab nuv ntses nrog cov nplua-nplua sandpaper, tom qab ntawd npog nws nrog tshwj xeeb GOI polishing muab tshuaj txhuam. Siv qhov muab tshuaj txhuam nrog ib daim flannel. Kev ua haujlwm zoo li no yuav khaws nws lub ci thiab tiv thaiv koj qhov ua tiav ntawm jig los ntawm oxidation. Tam sim no koj tuaj yeem mus nuv ntses.
