Iziphi izindlela zokubopha i-hollow blowing?

Isingeniso sendlela yokubumba i-hollow blowing:

Ngenxa yomehluko wezinto ezingavuthiwe, izidingo zokucubungula, okukhiphayo kanye nezindleko, izindlela ezihlukene zokubumba igalelo zinezinzuzo ezihlukene ekucubunguleni imikhiqizo ehlukene.

Ukubunjwa kokushaywa kwemikhiqizo engenalutho kuhlanganisa izindlela ezintathu eziyinhloko:

1, i-extrusion blow molding: isetshenziselwa ikakhulukazi ukucubungula i-billet engasekelwe;

2, ukubunjwa kokushaywa komjovo: ikakhulukazi esetshenziselwa ukucubungula i-billet esekelwe yinsimbi;

I-3, i-stretch blow molding: kufaka phakathi i-extrusion i-stretch blow molding, umjovo wokubumba i-stretch blowing izindlela ezimbili, ingacubungula imikhiqizo egxile ku-biaxial, yehlise kakhulu izindleko zokukhiqiza futhi ithuthukise ukusebenza komkhiqizo.

Ngaphezu kwalokho, kukhona multi-ungqimba igalelo ekubumbeni, ngokucindezela igalelo ukubumba, cwilisa enamathela vuthela ukubumba, ukubunjwa amagwebu, igalelo ezintathu-ntathu, njll Nokho, 75% imikhiqizo blow ukubumba kukhona extrusion igalelo ukubumba, 24% kukhona umjovo blow ukubumba kanye no-1% okunye ukubumba kokushaywa.Kuyo yonke imikhiqizo yokubumba i-blow, i-75% ingeyemikhiqizo yokwelula ephindwe kabili.Izinzuzo zokubunjwa kwe-extrusion blowulding ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi zemishini, ububanzi besikhunta kanye nokukhethwa kwemishini, okubi izinga eliphezulu le-scrap, ukugaywa kabusha kwemfucuza, ukusetshenziswa kabi, ukulawulwa kokuqina komkhiqizo, ukuhlakazeka kwezinto ezingavuthiwe kunqunyelwe, ngemuva kokubunjwa kufanele. kulungiswa ukusebenza konqenqemeni.Izinzuzo zokubunjwa kokushaywa komjovo ukuthi akukho imfucuza ngesikhathi sokucubungula, ukushuba kodonga lwemikhiqizo kanye nokuhlakazwa kwezinto ezibonakalayo kungalawulwa kahle, ukunemba kwemikhiqizo yentamo emincane kuphezulu, ingaphezulu lemikhiqizo libushelelezi, futhi ukukhiqizwa kwenqwaba encane kungenziwa ngokwezomnotho.Ububi yizindleko eziphezulu zemishini yokubumba, futhi ngezinga elithile kufanelekile kuphela emikhiqizweni emincane yokubumba.

Izimo zenqubo yokubunjwa kokushaywa okungenalutho zidinga ukuthi umoya ocindezelwe we-billet emaphakathi yesikhunta sokushaywa kufanele uhlanzeke.Umfutho womoya wokubumba umjovo ungu-0.55 ~ 1MPa;Ingcindezi yokubumba igalelo le-Extrusion ingu-0.2L ~ 0.62mpa, kuyilapho ingcindezi yokubumba i-tensile blow ngokuvamile idingeka iphakame njengo-4MPa.Ekuqinisweni kwepulasitiki, ingcindezi ephansi yenza ukucindezeleka kwangaphakathi kwemikhiqizo kube phansi, ukuhlakazeka kwengcindezi kufana kakhulu, futhi ukucindezeleka okuphansi kungathuthukisa ukushuba, umthelela, ukugoba nezinye izakhiwo zemikhiqizo.
