Chakumwa chakumwa cha botolo chowumba nkhungu chopangidwa mwamabotolo momwe mungasamalire makulidwe a khoma?

Kumwa botolo kuwomba akamaumba nkhungu mwambo dzenje kuwomba akamaumba ndi extruder ku extruder, akadali mu kufewetsa boma la tubular otentha pulasitiki billet pulasitiki mu nkhungu akamaumba, ndiyeno kupyolera wothinikizidwa mpweya, ntchito mpweya kuthamanga kwa billet mapindikidwe. pamodzi nkhungu patsekeke, kuti kuwomba mu khosi yochepa dzenje mankhwala.

Chakumwa botolo kuwomba akamaumba nkhungu makonda

Hollow blowing kumagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zowonda zopanda zipolopolo, zotengera zamankhwala ndi tsiku ndi tsiku, komanso zoseweretsa za ana.

Hollow blow molding (yomwe imadziwikanso kuti blow molding) ndi njira yopangira zinthu zopanda pake powombera mazira osungunuka otsekedwa mu nkhungu mothandizidwa ndi mphamvu ya mpweya.Ndi njira yachitatu yodziwika bwino yopangira pulasitiki komanso njira yopangira pulasitiki yokhala ndi chitukuko chofulumira.

Zomwe zimapangidwa ndi makina opangira mphutsi zimafunikira makulidwe a khoma lofanana.Nthawi zambiri, ziwiya dzenje m'munsimu 0.2L sangathe okonzeka ndi akusoweka khoma makulidwe chipangizo kulamulira.Nthawi zina, chida chowongolera khoma chopanda kanthu chiyenera kuganiziridwa, makamaka pazinthu zomangira zopanda pake zomwe zimakhala ndi zigawo zovuta.

Pakalipano, kulamulira makulidwe a khoma nthawi zambiri kumatheka mwa kusintha chiwongoladzanja cha milomo pakati pa chivundikiro cha mutu ndi kufa.Malinga ndi mawonekedwe osiyanasiyana a chivundikiro chamutu ndi pachimake chakufa, njira yosinthira yochotsa milomo imakhalanso yosiyana.Kuyenda kumtunda ndi kumunsi kwa nkhungu nthawi zambiri kumayendetsedwa ndi silinda ya hydraulic.

Makina omangira mpweya wapakati akamayendetsa chidebe chopanda pulasitiki chokhala ndi mawonekedwe osavuta, amatha kuzindikirika posintha ma hydraulic system.The electro-hydraulic directional valve imangovomereza mphamvu kapena chizindikiro cha mphamvu, kotero kuti silinda ya hydraulic mmwamba kapena pansi, mtunda wa kayendedwe ka hydraulic cylinder (ndiko, kusintha kwa kutsegula kwa nkhungu pakamwa) ndi mtedza wapamwamba ndi wotsika. set, liwiro la hydraulic cylinder movement ndi flow valve throttling action set, chizindikiro chamagetsi cha electro-hydraulic directional valve by the time relay control.

Njira yowongolera iyi ndi yophweka komanso yotsika mtengo, koma lamulo la kusintha kwa makulidwe a khoma ndi losavuta, pali mitundu iwiri yokha ya kusintha kwa makulidwe a khoma, angagwiritsidwe ntchito pofinya ndi kuwomba chotengera chosavuta chopanda kanthu.
