I-Compression Molding Method kanye ne-Compression Molding Equipment

Imishini eyinhloko yokukhiqiza ukubumba i-hydraulic press.Indima yomshini wokucindezela we-hydraulic enqubweni yokucindezela ukufaka ingcindezi epulasitiki ngokusebenzisa isikhunta, uvule isikhunta futhi ukhiphe umkhiqizo.

Ukubunjwa kokucindezela kusetshenziswa ikakhulukazi ekubunjweni kwamapulasitiki e-thermosetting.Ku-thermoplastics, ngenxa yesidingo sokulungisa okungenalutho kusenesikhathi, idinga ukushiswa nokupholiswa ngokushintshana, ukuze umjikelezo wokukhiqiza mude, ukusebenza kahle kokukhiqiza kuphansi, futhi ukusetshenziswa kwamandla kukhulu.Ngaphezu kwalokho, imikhiqizo enezimo eziyinkimbinkimbi nosayizi abanembe kakhudlwana ayikwazi ukucindezelwa.Ngakho-ke umkhuba ojwayelekile wokubumba umjovo ukonga kakhulu.

Iumshini wokubumba wokucindezela(cindezela ngokufushane) okusetshenziselwa ukubumba umshini wokucindezela osebenzisa amanzi.Umthamo wayo wokucindezela uvezwa ngamathani okuzisholo, ngokuvamile, kukhona ama-40t ﹑ 630t ﹑ 100t ﹑ 160t ﹑ 200t ﹑ 250t ﹑ 400t ﹑ 500t uchungechunge lwemishini yokunyathelisa.Kunamathani angaphezu kwe-1,000 emishini yokunyathelisa enezingqimba eziningi.Okuqukethwe okuyinhloko kokucaciswa kwabezindaba kufaka phakathi i-tonnage yokusebenza, i-ejection tonnage, usayizi we-platen wokulungisa ukufa, kanye nemivimbo ye-piston yokusebenza kanye ne-ejection piston, njll. Ngokuvamile, izifanekiso ezingenhla neziphansi zomshini zihlonyiselwe ukushisisa nokupholisa. .Izingxenye ezincane zingasebenzisa umshini wokucindezela obandayo (akukho ukushisisa, amanzi okupholisa kuphela) ukubumba nokupholisa.Sebenzisa umshini wokushisa ukushisa ngokukhethekileyo ukwenza ipulasitiki eshisayo, engonga amandla.

Ngokwezinga le-automation, imishini yokunyathelisa ingahlukaniswa ngemishini yokunyathelisa yezandla, i-semi-automatic press, kanye ne-automatic.Ngokuya ngenani lezendlalelo zepuleti eliyisicaba, lingahlukaniswa ngokucindezela okuphindwe kabili kanye nezingqimba eziningi.

I-hydraulic press ingumshini wokucindezela onikwe amandla yi-hydraulic transmission.Lapho ucindezela, ipulasitiki ifakwa kuqala esikhunjeni esivulekile.Bese uphakela amafutha okucindezela kusilinda esisebenzayo.Ngokuqondiswa yikholomu, i-piston kanye ne-beam ehambayo iya phansi (noma phezulu) ukuvala isikhunta.Ekugcineni, amandla akhiqizwa umshini wokunyathelisa amanzi adluliselwa esikhunjeni futhi asebenze epulasitiki.

Ipulasitiki ngaphakathi kwesikhunta iyancibilika futhi ithambe ngaphansi kwesenzo sokushisa.Isikhunta sigcwele ingcindezi evela emshinini wokunyathelisa we-hydraulic futhi ukusabela kwamakhemikhali kwenzeka.Ukuze ukhiphe umswakama nezinye izinto eziguquguqukayo ezikhiqizwa ngesikhathi sokuphendula kwe-condensation yamapulasitiki futhi uqinisekise ikhwalithi yomkhiqizo, kuyadingeka ukwenza ukukhululeka kwengcindezi kanye nokukhipha umoya.Khulisa ngokushesha futhi ulondoloze.Ngalesi sikhathi, i-resin epulasitiki iyaqhubeka nokusabela kwamakhemikhali.Ngemva kwesikhathi esithile, kwakheka isimo esiqinile esiqinile esingancibiliki futhi esingenakunyakaziswa, futhi ukubunjwa kokuqinisa kuyaqedwa.Isikhunta sivulwa ngokushesha, futhi umkhiqizo ukhishwa esikhunjeni.Ngemva kokuba isikhunta sesihlanziwe, umjikelezo olandelayo wokukhiqiza ungaqhubeka.

Kuyabonakala kule nqubo engenhla ukuthi izinga lokushisa, ingcindezi, nesikhathi kuyizimo ezibalulekile zokubumba ukucindezela.Ukuze kuthuthukiswe ukukhiqizwa komshini kanye nokuphepha nokuthembeka kokusebenza, isivinini sokusebenza somshini nakho kuyisici esibalulekile esingenakunakwa.Ngakho-ke, umshini wokunyathelisa we-hydraulic wepulasitiki osetshenziselwa ukucindezela kufanele ukwazi ukuhlangabezana nezidingo eziyisisekelo ezilandelayo:

① Ingcindezi yokucindezela kufanele yanele futhi ilungiseke, futhi iyadingeka ukufinyelela nokugcina ingcindezi enqunywe kusengaphambili phakathi nesikhathi esithile.

② I-beam enyakazayo yokucindezela kwe-hydraulic ingama futhi ibuye nganoma yisiphi isikhathi sokushaywa.Lokhu kudingekile kakhulu uma ufaka isikhunta, ucindezela ngaphambili, ukushaja inqwaba, noma ukwehluleka.

③ I-beam enyakazayo yomshini wokunyathelisa we-hydraulic ingalawula isivinini futhi ifake ingcindezi yokusebenza nganoma yisiphi isikhathi sokushaywa.Ukuze kuhlangatshezwane nezidingo zesikhunta sobude obuhlukene.

I-beam ehambayo yomshini wokunyathelisa we-hydraulic kufanele ibe nesivinini esisheshayo ku-stroke engenalutho ngaphambi kokuba isikhunta sesilisa sithinte ipulasitiki, ukuze unciphise umjikelezo wokucindezela, uthuthukise ukukhiqiza komshini futhi ugweme ukunciphisa noma ukuqina kokusebenza kokugeleza kwepulasitiki.Lapho isikhunta sesilisa sithinta ipulasitiki, isivinini sokuvala isikhunta kufanele sehliswe.Uma kungenjalo, isikhunta noma ukufakwa kungase konakaliswe noma impushana ingase igezwe esikhunjeni sowesifazane.Ngesikhathi esifanayo, ukunciphisa isivinini kungabuye kususe ngokuphelele umoya ekubunjeni.
