Inkqubo epheleleyo ye-extrusion ye-PTFE:Icandelo lokutyisa okuqinileyo, icandelo lokunyibilika, icandelo lokuNyibilika, icandelo lokuhambisa iNyibilika kunye necandelo lokuPholisa.
1. Icandelo lokutyisa okuqinileyo
Kweli candelo, ukhetho lwezixhobo luyinto ebaluleke kakhulu.Ukuze kuqinisekiswe umgangatho we-extrusion, izinto ezisetyenzisiweyo kufuneka zihlangabezane nezi meko zilandelayo: ubuninzi obukhulu, ukuhamba kakuhle kwamahhala, amaqhekeza kufuneka abe nokuzinza okwaneleyo kunye nobunzima, kunye nezinto eziluhlaza Ukucoceka, njl. Ekubeni icandelo lokutya okuqinileyo lihlukaniswe libe iinkqubo ezimbini, ukudibanisa umgubo kunye nokuhamba kweplagi eqinile, inkqubo yemveliso yeli candelo kufuneka ichazwe kule miba mibini.
①Umgubo wokudibanisa.Kweli candelo, xa i-plunger irhoxa, izinto ezikhululekileyo ziya kuwela kwigumbi lokubhoboza ngokwalo phantsi kwesenzo somxhuzulane, kwaye xa i-plunger iqhubela phambili ngokuthe ngcembe kwaye iqala ukucinezela izinto, amasuntswana akhululekileyo aya kuthi emva koko adityaniswe abe xineneyo. iplagi eqinileyo.Le nkqubo ngokuyisiseko yinkqubo yokuvelisa uxinzelelo lwe-extrusion ye-plunger yomatshini.
②Ukuhamba kweplagi eqinileyo.Xa izinto ziqhubeka nokuqhubela phambili kunye ne-plunger, iplagi eqinile iya kutyhala izinto kwi-barrel yonke phambili phantsi kwesenzo sepunch.Kwaye kule nkqubo, iplagi eqinileyo iya kufumana amandla okutyhala ukusuka kwisiphelo esingasemva kunye nesiphelo sangaphambili kunye nokuchasana, ngaloo ndlela igcina isixa esikhulu samandla.Xa i-plunger ifikelela kweyona stroke ikude, iqalisa ukuhlehla ngokukhawuleza.Ngeli xesha, izinto eziphathekayo ziya kukhulula amandla agcinwe ngaphambili, ukwenzela ukuba izinto eziphathekayo ziqhube phambili.Ngenxa yokuba i-PTFE ngokwayo ineempawu ezinkulu ezirhubuluzayo, xa i-plunger iyicinezela phantsi, umlinganiselo othile wamandla uya kugcinwa ngenxa yoguquko.Le nxalenye yamandla iya kukhutshwa ngokuthe ngcembe njengoko i-plunger irhoxa, kwaye le nkqubo iya kujikeleza ngasemva naphambili.
2. Icandelo lokunyibilika
Xa iplagi eqinileyo iqhubela phambili, iyakwenza ingxabano kunye nodonga lombhobho kwaye yenze ubushushu.Ngokudibanisa ne-heater ngaphandle kombhobho, ukushisa kweplagi eqinile kuya kuqhubeka nokunyuka, ukuze izinto ziqale ukunyibilika kwaye zivelise ukunyibilika kwinkqubo.inwebu.Ukunyibilika kwezinto ngokuqhelekileyo kuqala ukusuka kwindawo esondeleyo kwindonga ye-cylinder, kwaye ngokuthe ngcembe iyancibilika ukusuka ngaphandle ukuya ngaphakathi.Njengoko izinto ziqhubeka ziqhubela phambili, ubukhulu bobumba botyalo-mali buya kuqhubeka nokunyuka, kwaye i-radius yeplagi eqinile iya kuba Gcina incinci kwaye incinci de i-melt igcwalise yonke icandelo lombhobho.
3. Icandelo lokuguqula
Ngokuqhelekileyo inxalenye yokuqala yokubumba kombhobho iya kuba ne-cone ye-shunt, umsebenzi wayo kukwenza ukunyibilika okuhamba kule nxalenye kufake ikhonkco elincinci, elinceda ukutshisa kunye neplastiki kunye nokwenza umbhobho onqunywe kwangaphambili.Xa izinto zihamba ngeli candelo, uxinzelelo luya kwakhiwa ekunyibilikeni phantsi koxhathiso lwe-frictional cone ye-splitter kunye nezinye izixhobo, eziluncedo ekubunjweni kweemveliso ezixineneyo, kunye nezinto ezinokuthi zithotyelwe kwi-shear eqinile. eli candelo.Ukuya kuthi ga kwinqanaba elithile, ukunyibilika kwezinto eziqinileyo ezishiyekileyo kuyakhawuleza, kwaye izixhobo zinokunyibilika ngokupheleleyo xa zingena kwinqanaba elilandelayo.
4. Icandelo lokuhambisa inyibilika
Xa imathiriyeli ingena kweli candelo, iye yaba yimeko enyibilikileyo ngokupheleleyo, kodwa uxinzelelo lunokuguquguquka okuthile, kwaye i-PTFE inyibilika isenomgangatho othile wokunwebeka.Oku kungenxa yokuba izinto zihlala zikwinkqubo yokugcina amandla ukukhupha amandla kwinkqubo yokuqhubela phambili.Ukuze kuqinisekiswe ukuba intshukumo ingaqhubeka;kunye nokuqhubela phambili okuqhubekayo kwezinto, ukuguquguquka koxinzelelo kuya kuba kuncinci kwaye kuncinci, kwaye intshukumo iya kuzinza ngokuthe ngcembe.Ekubeni i-plunger punching extruder ithatha uyilo olude lokufa, yandisa ngokufanelekileyo ixesha lokuba izinto zihlala kwifayi, ngaloo ndlela iphucula ngakumbi ukufana kunye nokubumbana kwemveliso.Ngenxa yeqondo eliphezulu lokunyibilika kwe-PTFE ngokwayo, kuyimfuneko ukufudumeza ukufa ngexesha lokukhupha, kwaye ubude becandelo lokufudumeza buya kuchaphazela uxinzelelo kunye nesantya ukuya kumlinganiselo othile, ngaloo ndlela kuchaphazela ukusebenza kakuhle kwe-extruder.Ngokweziphumo zovavanyo olufanelekileyo, ixesha elide icandelo lokufudumeza, ubukhulu boxinzelelo lwe-extrusion kunye nokuba ngcono iimpawu ezibonakalayo zemveliso.Nangona kunjalo, ukuba icandelo lokufudumala lide kakhulu, linokubangela ukuqhekeka kwimveliso.Ukuze kulungiswe le ngxaki, icandelo lokufudumala lombhobho lingahlulwa libe ngamacandelo amathathu, icandelo ngalinye linokulawula ngokuzimeleyo ubushushu, kwaye umkhono we-aluminium wongezwa phakathi kombhobho kunye nendandatho yokufudumeza kombane, ukwenzela ukuba ibhalansi yomhlaba. ubushushu bombhobho bunokuqinisekiswa .
5. Icandelo lokupholisa
Eli candelo likhuthaza ukupholisa kunye nokubunjwa kwezinto.Ngethuba le nkqubo, ubushushu bezinto eziphathekayo bunokuthotywa ngaphantsi kwe-250 ℃, kunye nemfuneko yokuba iqondo lobushushu lingaphezulu kwe-200 ℃ xa izinto zikhutshiwe kwi-tube enodonga olubhityileyo.Emva koko, umbhobho okhutshwe kumbhobho obhityileyo kufuneka upholiswe emoyeni ukulawula ixesha lokupholisa.Kufuneka kuqatshelwe ukuba ukuba icandelo lokupholisa lifutshane kakhulu, imveliso iya kungena kwinqanaba lokupholisa umoya kwangaphambili, okuya kubangela ukuba umkhiqizo ube mkhulu kakhulu, unciphise izinga lokunciphisa, kunye nokwandisa uxinzelelo lwangaphakathi.Ukuze kuphuculwe umgangatho wemveliso, intonga engundoqo kufuneka ibe nkulu ngokufanelekileyo kunobude bombhobho ukuze kuqinisekiswe ukuba intonga engundoqo inokudlala indima efanelekileyo yokuxhasa kwinqanaba lokupholisa umoya kwimveliso.
