Ukugaya i-hydraulic extrusion

Ukugaya i-hydraulic extrusion ukwenza i-semi-solid abrasive ikhishwe kwezinye izingxenye (njenge-pressure chamber kanye ne-jet hole), ukuchithwa, ukupholishwa kanye ne-chamfering yendawo yesiteshi kanye nekhona, njengoba kuboniswe kuMfanekiso 1. Umshini ungalawula ingcindezi ye-extrusion, i-abrasive. ukugeleza kanye nesivinini. Izinhlobo ezahlukene zokugaya, usayizi wezinhlayiyana, ukuminyana kanye ne-viscosity yenkampani yenethiwekhi zingasetshenziswa ukukhiqiza imiphumela ehlukene yokugaya i-extrusion. Isithwali ngokuvamile siwuhlobo lwe-polymer eguquguqukayo semi-solid, engeza inani elithile lemiksi e-abrasive. Izithwali ze-viscosity eziseduze-eziqinile zisetshenziselwa ukugaya ngokulinganayo izindonga zangaphakathi kanye neziteshi ezinkulu zezingxenye. I-viscosity ephansi ivame ukusetshenziselwa ukugaya i-chamfering kanye nokugaya isiteshi esincane. Uma i-abrasive icindezeleka esiteshini esivinjelwe, i-viscosity ye-abrasive iyanda, ibambe ukukhuhla ngokuqinile endaweni. Kule viscosity, i-abrasive izogaya indlela. I-abrasive mass eqiniswe yi-extrusion ikhishwa ngesiteshi esivinjelwe, okungukuthi, i-viscosity evamile iyabuyiselwa, okuholela ekugayeni okuncane noma okungekho nhlobo. I-abrasive viscosity, ingcindezi ye-extrusion kanye nosayizi wesiteshi kunquma izinga lokugeleza kwe-abrasive, okuthinta inani lokugaya, ukufana kokugaya, usayizi we-chamfering ekhoneni. Izinga lokugeleza okunensayo lifanele ukugaya okufanayo, izinga lokugeleza okuphezulu lizokhiqiza ukujikeleza kwekhona elikhulu. Ibanga lokucindezela kwe-Extrusion lingu-0.7 ~ 22MPa, izinga lokugeleza kwe-abrasive lingaphezu kuka-3801/min. I-scrub esetshenziswa kakhulu i-silicon carbide, kodwa i-cubic boron nitride, i-alumina ne-emery nayo iyatholakala. Ubukhulu bezinhlayiya zesihlabathi busukela ku-0. 005 kuye ku-1.5mm. Isihlabathi esihle singafinyelela isiphetho esiphezulu. Ukujula kokusika okubangelwa isihlabathi ku-workpiece kuncike ekucindezelweni kwe-extrusion ekhethiwe, i-viscosity e-abrasive kanye nosayizi wesihlabathi.
