Kugadziriswa kwerabha extruder screw
1. Iyo yakamonyoroka screw inofanirwa kutariswa maererano neiyo chaiyo yemukati dhayamita yedhiramu, uye kunze kwedhayamita kutsauka kweiyo screw itsva kunofanirwa kupihwa zvinoenderana neyakajairwa clearance nedhiramu.
2. Mushure mokunge tambo yepamusoro ine dhayamita yakaderedzwa ye screw yakasakara inorapwa, iyo inoputika-resistant alloy inonzi thermally sprayed, uye ipapo pasi kusvika pakukura. Iyi nzira inowanzogadziriswa uye kugadziriswa nefekitari yekupfapfaidza, uye mutengo wacho wakaderera.
3. Overlay welding wear-resistant alloy pane chikamu cheshinda che screw yakasakara. Zvinoenderana nedhigirii yekupfeka screw, welding yepamusoro ndeye 1 ~ 2mm gobvu, uye ipapo screw inovhuniwa uye inogadziriswa kusvika pakukura. Iyi alloy inodzivirira kupfeka inoumbwa nezvinhu zvakaita seC, Cr, Vi, Co, W uye B, izvo zvinowedzera kusapfeka uye kusagadzikana kwegora. Zvidyarwa zvehunyanzvi zvekutarisa zvine mutengo wakakura werudzi urwu rwekugadzirisa, uye hazviwanzo shandiswa kunze kwezvinodikanwa zvakakosha zvema screws.
4. Hard chrome plating inogonawo kushandiswa kugadzirisa screw. Chromium zvakare isimbi isingapfeke uye isingadziviriri simbi, asi iyo yakaoma chrome layer iri nyore kudonha.
Kugadziriswa kwerabha extruder barrel
Iko kuoma kwemukati kwebhomba kwakakwirira kudarika iyo screw, uye kukuvara kwayo kunonoka kupfuura iyo screw. Kupurwa kwebhari ndiko kuwedzera kwedhayamita yemukati nekuda kwekupfeka uye kubvaruka nekufamba kwenguva. Heino nzira yekugadzirisa:
1. Kana iyo dhayamita yebhodhoro ichiwedzera nekuda kwekupfeka, kana ichine imwe nitriding layer, gomba remukati remubhodhoro rinogona kubvongodzwa zvakananga, pasi kusvika kudhayamita itsva, uye ipapo screw itsva inogona kugadzirirwa maererano neizvi. dhayamita.
2. Iyo dhayamita yemukati yedhiramu inogadzirwa uye yakachekwa kuti iitezve alloy, ukobvu huri pakati pe1 ~ 2mm, uye wozopedzisa kusvika pakukura.
3. Mumamiriro ezvinhu akajairika, chikamu chehomogenization chebhodhoro chinopfeka nokukurumidza. Ichi chikamu (5 ~ 7D kureba) chinogona kuchekwa nekufinha, uyezve chakashongedzerwa nitrided alloy simbi bushing. Kuwanda kwegomba remukati zvinoreva dhayamita yescuru. Iyo yakajairika fit clearance inogadziriswa uye yakagadzirirwa.
Zvinosimbiswa pano kuti zvikamu zviviri zvakakosha zve screw uye mbiya, imwe itsvimbo yakatetepa, uye imwe igomba rine dhayamita diki uye refu. Maitiro avo ekugadzira uye kupisa kupisa kwakanyanya kuoma, uye zvakaoma kuve nechokwadi chechokwadi. . Naizvozvo, kana kugadzirisa kana kutsiva zvikamu zvitsva mushure mekupfeka kwezvikamu zviviri izvi zvinofanirwa kuongororwa zvakadzama kubva pakuona kwehupfumi. Kana mutengo wekugadzirisa wakaderera pane mutengo wekutsiva screw nyowani, inosarudzwa kuigadzirisa. Iyi haisiriyo zvayo sarudzo yakanaka. Kuenzanisa pakati pemutengo wekugadzirisa uye mutengo wekutsiva chinhu chimwe chete. Mukuwedzera, zvinoenderana nechiyero chekugadzirisa mari uye nguva yekushandisa screw mushure mekugadzirisa kune inotsiviwa mutengo uye nguva yekushandisa yakagadziridzwa screw. Izvo zvine hupfumi kutora chirongwa chine chiyero chidiki, inova sarudzo chaiyo.
4. Zvishandiso zvekugadzira screw uye barrel
Kugadzira screws nemadhiramu. Parizvino, zvinhu zvinowanzo shandiswa muChina 45, 40Cr uye 38CrMoAlA.
