Imishini esemqoka yokukhiqiza yokubumba yi-Hydraulic Press.Iqhaza lomshini we-Hydraulic Cindezela kwinqubo ecindezelayo ukufaka ingcindezi epulasitiki ngokusebenzisa isikhunta, vula isikhunta bese ukhipha umkhiqizo.
Ukubumba kokucindezela kusetshenziselwa ikakhulukazi ukubumba kwamapulasitiki we-thermoset.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 kanye nosayizi oqondile abakwazi ukucindezelwa.Ngakho-ke, inkambiso ejwayelekile ibheke ekubumbeni okungaphezulu kwezomnotho.
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, i-action actage, usayizi weplanethi yokulungisa i-diste, kanye ne-ejection Piston, izifanekiso ezingenhla kanye nezitholile zezinhlelo zokusebenza zifakwe ngamadivayisi wokushisa nokupholisa .Izingxenye ezincane zingasebenzisa umshini wokucindezela obandayo (akukho ukufudumeza, amanzi apholile kuphela) wokubumba nokupholisa.Sebenzisa umshini wokushisa ngokushisa nge-thermal Plasticialization, 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 ngumshini wokucindezela unikwa amandla ukuhanjiswa kwe-hydraulic.Lapho ucindezela, ipulasitiki ifakwa okokuqala kwisibukiso esivulekile.Bese upha ukondla uwoyela wengcindezelo kwisilinda esisebenzayo.Kuqondiswa yikholamu, i-piston kanye nogongolo olushukumisayo luya phansi (noma phezulu) ukuvala isikhunta.Ekugcineni, amandla akhiqizwe yi-Hydraulic Press idluliselwa kubumbi futhi esebenza ngopulasitiki.
Ipulasitiki ngaphakathi isikhunta incibilika futhi ithambe ngaphansi kwesenzo sokushisa.Isikhunta sigcwele ingcindezi evela ku-hydraulic Press kanye nokusabela 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 nokuphendula kwamakhemikhali.Ngemuva kwenkathi ethile yesikhathi, kwakhiwa isimo esiqinile sokungapheli futhi esingenasisekelo, futhi ukubumba okuqinile kuqediwe.Isikhunta sivulwa ngokushesha, futhi umkhiqizo uthathwa kulokhu.Ngemuva kokuthi isikhunta sihlanzwe, 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:
Ingcindezi ecindezelayo kufanele yanele futhi iguqune, futhi iyadingeka futhi ukuze ifinyelele futhi ilondoloze ingcindezi enqunyelwe kusengaphambili esikhathini 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.Ukuhlangabezana nezidingo zezikhunta zokuphakama okuhlukile.
Ugongolo olushukumisayo lwe-Hydraulic Cindezela kufanele lube nesivinini esingenalutho esihlatshelweni esingenalutho ngaphambi kokuba isikhunta besilisa sithinte umjikelezo ocindezelayo, ukunciphisa umjikelezo ocindezelayo, sithuthukise ukukhiqizwa komshini futhi uqinise ukuncishiswa noma ukuqina kokusebenza kwepulasitiki.Lapho isikhunta sabesilisa sithinta ipulasitiki, ijubane lokuvala isikhunta kufanele sehliswe ihliswe.Ngaphandle kwalokho, isikhunta noma ukufaka kungenzeka konakaliswe noma i-powder ingagezwa kwabesifazane isikhunta.Ngasikhathi sinye, wehlisa ijubane ijubane lingasusa ngokuphelele umoya kusikhunta.
