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. For thermoplastics, due to the need to prepare the blank in advance, it needs to be heated and cooled alternately, so the production cycle is long, the production efficiency is low, and the energy consumption is large. Ngaphezu kwalokho, imikhiqizo enezimo eziyinkimbinkimbi kanye nosayizi oqondile abakwazi ukucindezelwa. Ngakho-ke, inkambiso ejwayelekile ibheke ekubumbeni okungaphezulu kwezomnotho.
Le khasiUmshini wokubumba wokuxhuma(Cindezela amafuphi) okusetshenziselwa ukubumba yi-Hydraulic Press. Umthamo wayo ocindezelayo uvezwa ku-tonnage engokwesifiso, ngokuvamile, kukhona 40t ﹑ 630t ﹑ 100t ﹑ 16t ﹑ 200t ﹑ ama-400t uchungechunge lwemishini yokushicilela. Kunamathani angaphezu kwe-1 000 emishini ehlukahlukene ehlukahlukene. Okuqukethwe okuyinhloko kokucaciswa kwabezindaba kufaka phakathi i-tonnage, i-action towage, usayizi weplanethi yokulungisa i-diston esebenzayo ne-ejection ye-piston ne-ejection, izifanekiso ezingenhla zendaba zifakwe amadivayisi wokushisa nama-apholile. Izingxenye ezincane zingasebenzisa umshini wokucindezela obandayo (akukho ukufudumeza, amanzi apholile kuphela) wokubumba nokupholisa. Sebenzisa umshini wokushisa ngokushisa nge-thermal Plasticialization, engonga amandla.
Ngokuya ngezinga le-automation, ukucindezela kungahlukaniswa ngemishini yokucindezela ngesandla, ukucindezela okuzenzakalelayo okuzenzakalelayo, nokungcibisha ngokugcwele okuzenzakalelayo. Ngokuya ngenani lezendlalelo sepuleti elisicaba, lingahlukaniswa libe yisendlalelo esiphindwe kabili nemishini ehlukahlukene ehlukahlukene.
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 bakhiphe umswakama kanye nezinye izinguquko ezikhiqizwa ngesikhathi sokuvunyelwa kwamapulasitiki futhi uqinisekise ikhwalithi yomkhiqizo, kuyadingeka ukwenza impumpune yokucindezela nokuphelelwa amandla. Masinyane khuphula futhi ugcine. 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.
Kungabonakala kwinqubo engenhla yokuthi izinga lokushisa lezokushisa, ingcindezi, nesikhathi izimo ezibalulekile zokubumba kokucindezela. Ukuze uthuthukise umkhiqizo womshini kanye nokuphepha nokwethenjwa kokusebenza, ijubane lokusebenza lomshini libuye libe yinto ebalulekile engenakunakwa. Ngakho-ke, umshini wokucindezela we-hydraulic wepulasitiki osetshenziselwa ukucindezela kufanele ukwazi ukufeza izidingo eziyisisekelo ezilandelayo:
Ingcindezi ecindezelayo kufanele yanele futhi iguqune, futhi iyadingeka futhi ukuze ifinyelele futhi ilondoloze ingcindezi enqunyelwe kusengaphambili esikhathini esithile.
② Ugongolo olushukumisayo lwe-hydraulic Press lungama lubuyise noma yiliphi iphuzu ekuhlathini. Lokhu kuyadingeka kakhulu lapho ufaka isikhunta, ukucindezela kwangaphambili, ukushaja kwe-batch, noma ukwehluleka.
③ Ugongolo olushukumisayo lwe-Hydraulic Press lungalawula ijubane futhi lusebenzise ingcindezi yokusebenza nganoma yisiphi isikhathi ekuhlathini. 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.
