1. Ua ntej pib lub tshuab, xyuas seb qhov ntsuas kub tswj tau yooj yim puas siv, seb lub ntsuas hluav taws xob tsis zoo, seb lub tshuab cua txias yog du, thiab lwm yam. Feem ntau cov ntsuas kub, dej txias thiab lwm txoj kev siv los kuaj xyuas.
2. Raws li cov txheej txheem kev ua haujlwm ntawm extruder, cov ntsia hlau, chim thiab tuag lub taub hau ntawm extruder yog rhuab, thiab tom qab qhov kub nce mus rau qhov kub thiab txias, nws yuav tsum tau khaws cia sov li 10 feeb ua ntej nws tuaj yeem pib, kom lub qhov kub ntawm txhua feem ntawm lub tshuab nyhav kom ruaj khov.
3. Ua ntej pib lub tshuab, nws yog ib qho tsim nyog yuav tsum tau ceev cov ntsia hlau txuas thiab bolts ntawm txhua qhov ntawm qhov tuag thaum nws kub. Ua ntej cov khoom siv extruded, tus neeg teb xov tooj yuav tsum tsis txhob sawv ncaj nraim rau pem hauv ntej ntawm qhov tuag los tiv thaiv bolts lossis screws los ntawm kev tawg thiab ua rau raug mob.
4. Thaum pib extrusion, cov ntsia hlau ceev yuav tsum tau qeeb, thiab maj mam nce ntxiv kom tsis txhob overload thiab puas rau cov khoom thaum pib.
5. Thaum pib lub tshuab, ntxiv ib qho me me ntawm cov khoom ua ntej, thiab khaws cov khoom noj kom zoo, ua tib zoo mloog rau ntau lub rooj qhov tseem ceeb xws li torque thaum pub mis, thiab tos kom cov khoom extruded los ntawm lub taub hau thiab qhov ncauj tuag thiab rub cov khoom siv traction, kom maj mam nce cov khoom kom txog thaum ib txwm extrusion.
6. Lub taub hau tuag, txwv tsis pub nws yuav ua rau lub taub hau tuag tawm qhov txawv txav thiab ua rau cov khoom tawg lossis pwm ntsaws), cov duab yog qhov nyuaj, cov kab noj hniav me me thiab lub hau npog ntawm cov pwm pwm yuav tsum tau qhib rau ntau qhov. kab noj hniav profiles; Tom qab paub meej tias cov yas ntawm cov khoom siv extruded yog qhov qub, cov khoom raug rub mus rau lub tsheb laij teb los ntawm cov hlua khi hlua. Txo qhov kev ncua deb ntawm lub rooj teeb thiab lub taub hau tuag, npog lub hau npog, pib lub tshuab nqus tsev twj, thiab thaum lub extrusion ceev thiab traction ceev yog qhov sib npaug, soj ntsuam qhov profile mus rau qhov qub extrusion thiab tom qab ntawd txo qhov kev ncua deb ntawm lub rooj teeb. thiab tuag taub hau mus rau qhov zoo tagnrho tus nqi.
7. Yog tias nws pom tias lub parison tsis tsim nyob rau hauv qhov kawg ntawm qhov shaping tuag los yog lub puab tsaig adheres rau lub puab kab noj hniav nto ntawm qhov profile, ib tug taw tes cuab tam yuav siv tau rau poke ob peb qhov me me nyob rau hauv lub unformed ib feem los yog sab hauv tav ib feem ntawm lub parison ntawm qhov nkag kawg ntawm thawj ntu ntawm shaping tuag, yog li ntawd cov kab noj hniav me me txuas nrog cov cua, thiab lub parison qhib thaum nws nkag mus rau shaping tuag, uas yog yooj yim rau kev tsim ntawm qhov tsis zoo. siab thiab txhawb nqa lub parison kom ze rau lub pwm phab ntsa ntawm shaping tuag.
8. Nyob rau hauv cov ntaub ntawv ntawm pwm plugging (tsis thaiv), lub rooj teeb yuav tsum tau tsiv rov qab los yog lub traction ceev yuav tsum tau nce tam sim ntawd, los yog cov saum toj no ob schemes yuav tsum tau siv nyob rau tib lub sij hawm, thiab ces cov khoom ib txwm yuav tsum tau resumed los ntawm. kev hloov kho. Yog tias qhov kev siv ntawm cov phiaj xwm saum toj no tau raug thaiv, lub rooj teeb tsa yuav tsum tau tsiv rov qab tam sim ntawd, thiab cov khoom yuav tsum tau shoveled raws cov pwm shaping, cov dej vapor ntawm cov shaping tuag yuav tsum raug kaw, traction ceev yuav tsum tau txo, thiab qhov profile yuav tsum tau maj mam rub tawm ntawm lub shaping pwm. Yog tias ib feem ntawm qhov profile tau tawg hauv qhov chaw tuag, nws yog qhov yuav tsum tau disassemble qhov chaw tuag thiab ntxuav tag nrho cov khoom seem.
9. Thaum lub tshuab nres, feem ntau yuav tsum tau ntxiv cov khoom siv nres kom nyem tawm cov khoom siv hauv lub tshuab, thiab tom qab ntawd nres lub tshuab thiab disassemble lub taub hau tuag thaum nws kub rau pwm tu.
